Yes, my heart was pounding the whole time! Next time should be less pressured, now that I know it doesn't have any obvious bad habits. I'm waiting for the field to dry out before flying it again. We have had heaps of rain, and everything is soaked.

Thanks for the helpful info!

@@RCJim Also, the AR636 doesn't use a 2nd channel to control the gains. When you set up the AS3X menu in your transmitter, it creates a mix that uses the transmitter's flight mode system to store the gain setting for each of the receiver's flight modes. When you put the receiver's flight mode channel on a 3-position switch, the default values are -100, 0, and +100 percent. The mix can offset these values up to 45% each way. So, flight mode 1 can be from +55% to +145%, flight mode 2 can be from -45% to +45%, and flight mode 3 can be from -145% to -55%. My DX9 and iX14 can use the left or right trim levers to adjust the gyro gain. A DX6e can use the scroll wheel, but you must put the transmitter in the AS3X menu before taking off. Otherwise, the scroll wheel can't adjust the gain. Several years ago, we used to enable only the roll gain on one position of the switch, enable only the pitch gain on the middle position, and enable only the yaw gain on the 3rd position. With the other gains set to zero, we could test each axis independently. We'd take off and set the roll gain, flip the switch and set the pitch gain, flip the switch again and adjust the yaw gain. That was a lot of trouble, so I just started setting the roll gain to 30%, the pitch gain to 40%, and the yaw gain to 50%. I'd set all of the priorities to 150% because with the dual rates set to 50% (the lowest I ever go), the gyro gain would decrease to zero just as the stick hits the stop. With the servo travel and dual rates set to 100%, the gyro gain would decrease to zero at one-half stick deflection. You don't want any gyro gain at full stick deflection and need it the most near neutral, so having the gain decrease to zero somewhere between 1/2 and full stick deflection is fine. And yes, take the prop off. AS3X doesn't activate until you open the throttle above 25%, so you must run the motor before checking the gyro direction. I used to use heading hold before I started setting up SAFE mode. You shouldn't use it on yaw with an airplane, but it works well on roll and pitch. It can eliminate the need to use RUD>AIL/ELE mixing to straighten your plane out in knife edge flight.

Thanks again for the detailed information!

That's consistent with the sort of issues that Tai is having with his. But, it doesn't want to get up into the air, and when he tries to force it up, it stalls. We have found that the angle of incidence of the wing on his plane is too low, and the wheels don't roll very freely. He is repowering it with an electric motor and will try to sort out the issues. I hope to avoid all of that from the beginning! I learned to fly in a Citabra, and would love to have a model to rekindle the memories!

The gasoline engine develops slightly less power as compared to a 2 stroke glow fuel engine with the same displacement, but more power than a 4 stroke glow fuel engine of the same size. An OS GGT 15 has a displacement of 0.912 cu. in. and is stated to develop 2.32 HP (2.54 HP per cu. in.). The OS Max 95AX (2 stroke) has 0.949 cu. in. displacement and is rated at 2.86 HP (3.01 HP per cu. in.). The OS FS-95V W/F (4 stroke) has 0.95 cu. in. displacement and develops 1.68 HP (1.77 HP per cu. in.).

@@RCJim thanks a lot Jim, this means that OS GGT 15 can be a good replacement option for OS 95 AX due to the high cost of nitro fuel as compared to gasoline, I am talking about the scenario in 🇮🇳 India.

Yes, nitro fuel is really expensive here as well. It makes sense that gasoline would deliver more power as much of the nitro fuel is lubricant. Keep in mind that if you are comparing with the 95AX, you will have 19% less power due to the 2 strokes developing more power than the four strokes. Depending on the plane, that might not be an issue for you.

@@RCJim👏great, I would like to know if the OS GGT will be fine on a .60 size plane, or what size plane you recommend best for OS GGT 15

It would give you a fair bit of extra power. An OS Max 65AX develops 1.73 HP. Since the 95 four stroke (FS-95V) would have just a little less power than that, I expect it would be commonly used as a substitute, even though it is nearly 100g heavier. The GGT 15 is only 18g heavier than the 95 four stroke, but develops significantly more power than either the 65AX or FS-95V. So, you should do well with the GGT 15 on a 60 size plane.

Me lo aspetto anch'io. È strano che un altro aereo come questo abbia questi problemi.

I actually tried floats on this one way back when. Unfortunately they were not quite big enough. The plane would float fine with the engine not running, but with it even at idle it would dump over forwards! ...actually, I still have those floats as well - hanging in the garage!

Yes Bill, my initial motivation was related to the great memories. But, now that I have flown it, I'm drawn by the fantatic way it flys - even if it doesn't look like much!

Hi Brian, This is the first time I have used one. I flew it today, and it went great. Given the long range potential that they have, it's hard to imagine someone losing a plane that they are operating in line of sight. I'll do some further testing on this and will provide a video update.

Oops, sorry, I was thinking you were asking about the ELRS receiver that I just put in the Duraplane. With Lemon RX I have used them extensively and have had no issues at all.

L'ho pilotato oggi, ed è stato fantastico! Il rollio è bello e dritto, e fa bene tutte le acrobazie. E gli atterraggi possono essere fatti a una velocità ragionevolmente alta con un assetto a muso in su.

That makes sense. The biggest issue that I have with mine is where to store it. We need to come up with a design for one the folds!

@RCJim oh ya shoot, lol. Never thought of that. I was also thinking of pvc construction as well

Let us know what you come up with!

Glad to hear it was helpful.

Yes, channel 7 is used for that.

Glad it helped!

Thanks for the info!

No worries. Hope it was helpful. An observation from training a fellow today: In the turns you will need to pull back on the elevator - but not too early. This guy was pulling up into a climb while entering the turn, banking too steep, then losing heaps of altitude. Watch what is happening to the plane, and only add elevator as and when needed. Another thing this guy was doing was using "knee jerk" reactions on the controls. Apply the controls smoothly and only as much as needed.

Use the NX10 as the trainer and the DX5e as the student. Then you can use the normal wireless buddy box system. The DX5e only needs to transmit a normal signal. The receiver inside the NX10 will pick up that signal when it is bound to the student radio. Alternately you can use a wire link between the two.

Hi Frank, that's a bit strange. Normally you would have the full throttle range going from stick all the way down to it being all the way up. Does the prop actually go into reverse when pulling the stick back? If so, I'm quite sure it is an issue with the ESC programming. Check out czcams.com/video/d-S7eg86j68/video.html.

@@RCJim Yep - ESC. I was focused on the transmitter. Didn't realize that the throttle relates to the speed controller. I was using an ESC that was designed for boats only. Thanks for the help 🙂

Glad that you have it all sorted!

It has a good range. I haven’t tested the variometer, but if you are not in a rush, I’ll test it out over the next few weeks.

Analog switch setup would allow you to configure a rotary knob to a digital output, but most likely you would simply be assigning the knob to a channel. You would do that for continuous fine adjustment of flaps or airbrakes, etc.

Thanks 👍

Yes, it was great meeting you. I would recommend a FMS Ranger 1800. Most guys like the Spektrum transmitters, but they are expensive. Given that you are quite IT savvy, you might want a Radiomaster TX16S - 4 in 1. With that you get a 16 channel radio with all the 'whistles and buttons' at a cost lower than a Spektrum 6 channel radio. It's one of the preferred radios for FPV (drone) pilots. An ordinary Lemon RX 7 channel receiver will do a fine job in the plane. On second thought, you will probably want to work with an instructor at the club. Given that is the case, ask them about what transmitter to get, as it will need to be compatible with what they are using.

You don't need the stabilization as the 1800 Ranger comes with a stabilization module. Stabilization helps to automatically correct for wind gusts, etc.: studio.czcams.com/users/videocbNM9GDuD9M/edit. You will need a 4S 3300 mAh LiPo battery (or two) with XT60 connectors as well as a charger. You should be able to Google all of the above to find the lowest cost online. To get the latest Lemon RX receiver with the ability to program it from your radio, you should get it directly from them: www.lemon-rx.com. As you get into it and have questions, please ask.

I see there is now a firmware update for the NX6 that brings it up to 14 channels along with some other enhancements. That narrows the difference between it and the Radiomaster .

Hi Jesus, Sounds like you have a great power/plane configuration! The sky is the limit! By the way, I also think you have a great name - the same as my very best friend. Jim

What I can say is that it works with the -100 +100 range. Typically I have mine set in the negative territory. I think what gain does is to increase or decrease the amount of stabilization roughly by the percentage of the dial setting. I'm guessing that setting yours for a range of 0 to 100 should give you a range of 'standard' stabilization to roughly double that. Is that what you are experiencing? In the meantime I'll check with the factory guys so we can get it right from the horses mouth!

​@@RCJimStill waiting on mine to be delivered so I'm not sure. Just getting prepared for it.😁 I can say that on another brand when using -100 to +100, that it doesn't seem to have any effect until you get to the right side of center on the pot. Suppose it wont hurt to hear it from the horse's mouth just to be sure. Thanks! Norm

@@TheGoodLife62 -100 to +100 is correct. Here's what Frederick from Lemon RX has to say: For some radio likes Spektrum, it uses -100% to +100% as scale with the mid-point being 0%. It's correct that -100% means stabilization very close to off (actually the Spektrum radio minimum is -150%, but -100% is almost off) and 100% will have about double of the gain. It is not recommended to have an offset for channel 8 because this will limit the scaling for one side, thus, gain tuning is not fully utilized.

@@RCJim Thanks Jim!🍻

@@TheGoodLife62 No worries! Glad to help.

Glad to hear that! Thanks.

I did think about that very fact. What I am going to do is see if I can find the mounting point for the bar that is supposed to be there, and make really certain that it stays put!

A further thought about velcro on the RX. In this case, I have to pull out the RX in order to adjust the pots for stabilization. The velcro allows me to do that. Perhaps after I have finalized the settings, then I could replace the velcro with double sided tape. Alternately, perhaps attach it to a panel that slides in and out of guide rails.

That makes sense. I was quite surprised to see in the manual that they recommend using the high rates for takeoffs and landings. I think that is because the controls are a bit sluggish without a prop blowing air across the control surfaces. But I'm still using the low rates.

Hi Mike, My understanding is that this is a brand new development - first available a few weeks ago. Jim

@@RCJim OK - thanks JIm

Hi Fred, I don't have a DX9, but I cannot imagine that it couldn't do what could be done with a DX6e. Have you updated your firmware?

Faster with lights

So where's the spectrum finishing ?

So basically he didn't do the spectrum

@@charlesrestivo870 correct- I only go through the menu on the Radomaster because it should be the same with a Spektrum.

Hi Brett, you need to update the firmware in your transmitter. Have a look at czcams.com/video/PkQQPBWEr48/video.html. It's a bit on the complicated side. One day I'll produce my own video on how to do that as simple as possible, but for now you can do your best to follow the instructions from others. The Edge TX site has basic instructions, and CZcams videos give some further help.

Fortunately the vibration on the stick from my nerves didn't mess it up!

Yes, and it was a good day. I thought about saying something about the snow skier visiting the club that day, but figured that the viewers would figure out what that was about! :-)

Thanks for sharing.

The only one I have for Hobbyking Skywalker is this one that you have watched.

Thanks for your reply I’ve sent a message to Hobbywing asking for a video on how to connect the skywalker v2 esc to the LED program Box, I also noticed that the new V2 esc has trust reverse wire so I wonder if that wire needs to be plugged into the program box as well. Theses a heap of videos on how to use the program box with the car esc but not the v2 aircraft esc and I can’t get it working

I found this video that helps czcams.com/video/ooPkDbvPxgA/video.htmlsi=Cmp1O1ua6tSblcmr

Excellent, glad to hear that!

It's brand new - wasn't available until very recently.

It's brand new - wasn't available until very recently.

@@RCJimdo I need to upgrade something to get it?

I don't know if a simple firmware update will give the Gen 2 features, but I'll ask the guys at the factory.

@@RCJim thanks!

A common issue with many of us. That's why I have been searching for products such as the Lemon RX receivers to bring the costs down without sacrificing quality and capability.

That's great unless your toy plane crashes because it wasn't configured properly. None-the-less, at times I do get carried away with trying to understand every little thing about our hobby. For me there's a lot of interest in working out the details of how things work, and how we can make them better.

Thanks! I actually watched it again myself yesterday - just to make sure that it's still all good.

Glad it was helpful!

Thanks. If you are interested in the Lemon RX receivers, check out our recent video on programming their new Gen 2 receivers with your transmitter: czcams.com/video/cbNM9GDuD9M/video.html

Perhaps someone else has registered it, and has not released it. Did you get it second hand?

@@RCJim Yes I did, It was working on a Corsair S (HBZ8200)

I think the previous owner would have to notify Spektrum through their website to indicate that they no longer own it.

No worries. The Centre of Gravity is the balance point for the entire aircraft. It's important because if it is too far forward or aft, you will not be able to control the plane. Too far forward and it will just dive towards the ground as the airspeed lowers. Too far backward, and it doesn't want to fly straight. As the weight of the plane needs to be supported by the wing, the point where the lift on the wing is centred needs to be close to where the weight of the whole plane is centred. When you balance a plane on your fingers, you are basically doing the same sort of thing - as long as your fingers are on the fore-aft location of where the lift is centred. I'll give this some more thought and see if I can do another video to explain it clearly.

If you added a tail onto a flying wing, the weight of the tail would move the CG towards the back. The location of lift on the wing would not change. So, you would need to add weight to the front to get it to balance near the centre of lift.

@@RCJim Thanks for your response/clarification.

Glad to help!

No worries.

Yes, I have used it with my Radiomaster TX16s with Edge TX. I use DSM X2F for the protocol. The radio complains that the signal strength is low, but it seems that this is due to Spektrum having a different system for reporting signal strength than Radiomaster. I have not experienced any actual control problems. But it is a bit un-nerving!

@@RCJim I am having trouble setting up the safe mode. I have a 3 position switch set as my flight mode switch on my radiomaster tx16s and that appears to kind of work as in FM1 I can use that switch to turn off the gyro and in FM2 and FM3 I get AS3X. However I want FM3 to activate SAFE But I can't t get it to do that. The AR636A rx has safe built in and I believe SAFE has been activated within the rx as on start up the control surfaces do the double dance confirming that it is in SAFE mode but when I flick the FM 3 position switch the plane doesn't try and correct its self from inverted to the right way up. Pls help if you're able to.

@@786free1 Sorry, right offhand I’m not sure of what to do with that. I don’t use SAFE at all. I can say that the plane will do its start up dance when only AS3X is being used.

@@RCJim I managed to get it working. Thanks any way and keep making the very helpful videos.

Glad to hear that!

Glad to hear it!

Very welcome!

Yes, it is a bit of a challenge getting it up off the grass, but our paved runway is only about 100 feet long. However, I didn't use the flaps on takeoff. I'll use partial flaps the next time. And this is now our wet time of year. In the summer the ground will be harder and the grass less 'grabby.' So, what could go wrong? :-)

@@RCJim I like to use 15° of flaps for all takeoffs and 30 to 40 degrees for landing (depending on the plane) if the wind is calm.

Yes, I like the plane and the hanger on pulleys. Pulling the rope to get up and down, however, can be a bit of a challenge in that I have things on the wall that get in the way...
