- The Aerofoam T-45 is my funnest plane to fly to date. In this video I'll show how I build/set mine up. I made a few substitutions to the stock electronics which are not required. Just my preference. I also talk about the importance of thoroughly inspecting all flight surfaces, joints, servos e.t.c during the build process. All in all this was a fairly smooth process and took me about 10hrs to complete, start to finish, including all my mods. Enjoy!

This is a great video! Thank you for taking the time to do this. I’m hovering over this one and can see things I’d like to change and will need to check during the build process! Love this
Excellent walk through Frank. Always a good idea to go through everything for all the reasons you found. Little things turn into big things. That attention to detail saves planes! Beautiful model and flier my friend.
Thanks David! I try to be thorough and most of the times it pays off!
Really good video, thanks for showing us these tips.
Assemble are interesting work and need special skill, good job my friend
Mine is on pre-order and due in May. I'll be installing a KT-85. Nice job on the assembly and good things to look out for.
Awesome video.. i plan on ordering my jet once it comes off back order.
Beauty!!
It's a good thing you took the time to go over the model. All thought little things could cause you issues in flight. And if something goes wrong you scratching your head trying to figure out what went wrong. You would think it's just "PNP" lol.
Go idea to pump both tanks more flight time. I do the same with mine, also we can't use smoke at the field anyway. I do 7 min and still have lots of fuel left.
Your first flight I would keep it do 7 min then check to see how much fuel you have left.
I also have a telemetry sensor setup to calculate how much fuel is being used and calls it out to me. And some of the info that is displayed on the GSU is show on my TX. No need to connect the GSU all the time.
I'll have to try one of those Smooth Lite on next build it pretty impressive what it can do.
Good luck with your maiden I know you'll be just fine.
I pickup a K45 going to try to convert one of my 90mm EDF to turbine.
very good indepth review you have identified qualitative control issues and some engineering problems with elevator carrier bearing.replacement of carrier bearing or redesign is a must, l do believe it could fail in flight.
I certainly appreciate all the details It will certainly help a lot in my build My 1st question what size 3MPM screw did you use for your redder? I saw other concerns about the elevator assembly about the elevator assembly I definitely will take will take a longer look at mine especially aftespecially after what you discovered.
I just used what I had lying around. I think it was from an M3 kit I bought on amazon
I agree. I have one on the way and this is good info. I know to check over everything. I was looking at the LG-13 unit that is a little cheaper, should do the trick.
Nice assembly my guy 🗣️💯💯 I bought the T45 Pnp version . I would like to know what batts to run . I saw you use a 2s 2200 for the landing gears . Then I see 4 other connection. Two for the LIFE batts that you said was 3s but what size ? Can you tell me what are all the batts you are using ?
I use 1x 3S 2200mah LiFe for the turbine. Then 2x 2s 2200mah Lipo for my AR SmoothFlite 16 box. The last is a 2s 2200mah Lipo for the landing gear and brakes. That connects to the Xicoy LG 15 gear and brakes controller
@@FlyWithFrank ok thanks so 4 batteries in total ..would I need the same batteries for the stock version ??
Excellent video Frank. Thank you very much for sharing. Where are you and your club located?
Thanks sir!! I am in Northern California. This club field is located in Crows Landing California.
I was just in the area a few weeks ago in Menlo Park CA. Will try to plan visit to check out the club field when I am back in that area.
What's your take on the differential braking? Mine is coming with it installed.
It works well especially in conjunction with the nose wheel steering. You just have to get the gains right
Frank, I have purchased a Xicoy LG-15 to use in the AF T-45 turbine. Could you kindly tell me what settings you found to work (volts & amps) for the nose gear, main gear and nose door servo? Also, you mention in your video that you are using a remote starter and you point to it but it is very hard to see. Can you tell me what starter this is please? Thanks so much!!
Hi Paul Yes. I will post the LG15 settings here. The remote starter is the AR Booma RC SmoothFlite remote key fob. It works with the SmoothFlite system.
@@FlyWithFrank Thank you Frank - I will watch for them!
Frank can you please share what you found the setting in the LG-15 needed to be? Thanks!
I bumped the Current on all landing gears to 2.0A. Nothing else on the Motors screen (18:02) changed
I don’t know if there is a forum dedicated to this rc model so I’d like to ask any of you that had the chance of flying this model. How does it handle compared to a jet that is built out of comp materials e.g fiberglass. I am interested in buying one of these and it will be my first jet, so I prefer something reasonably priced!
Have you had any servo issues running unregulated 2S LIPOs for the electronics?
The only one I had issues with was the nose gear door servo. I later found that it was under a lot of stress when the gear was up and doors were closed. I replaced it and adjusted accordingly. No more issues!
@FlyWithFrank How did you setup the flaps and slats with the AR Smooth Flite 16?
Frank - I am still trying to get everything working properly with my Xicoy LG-15. As the plane arrives from AF their landing gear controller gets is power from the receiver and is 6 volts. In your setup, you show a 2S battery connecting to the LG-15 controller so I would guess you are now running you landing gear motors at 7.4 volts. Can you please confirm that you are running the gear at 7.4 volts and have had no problems doing that? Thanks so much!
Hi Paul. Yes I am running the gear on a 2S lipo, which means it actually goes upto 8.4v. I have not had any issues so far and have had quite a few flights on it. Now, that said, my T45 was one of the earliest versions and I believe they changed out the landing gear motors for subsequent planes. Ralph Salgado would know more.
@@FlyWithFrank Thanks!
Mine is coming in soon. Have you confirmed all servos are hv (8.4v) capable? I see you say that in your video, but where did that info come from? Thanks for the help!!
The description on the global aerofoam jetclub say the servos are hv. But I tested them using an 8.4v power system. I had them plugged in for about 20 minutes. No overheating or anomalous servi behavior
@@FlyWithFrank Thanks!
I see your lights come on when you power up the Smoothflight. How did you set this up? The light module is always on with the battery plugged in. I opened up the light controller box and all it is, is a power distribution bix for the LEDs. All of the ports are the same.
Hi HornetFlyer... yes the light controller just runs off if a servo channel on the SmoothFlite16. I am running 2x2s lipo on the SmoothFlite16 since all the servos can handle 8.4v ok. The SmoothFlite16 has a key fob to turn on the unit and since my lights draw power from that, turning on the unit turns on power to leds and vice versa, when off. For the landing light, I had to get a receiver controlled switch and then plugged the pwm lead into the SmoothFlite16 and the power lead into the led controller than comes with the plane. This way I was able to mix my gear switch to that landing light to turn it on or off depending on gear up or down
@@FlyWithFrank great stuff Frank. Thanks for the explanation. I, too, am planning to use the Smooth Flight 16 on mine. I have Xicoy LGC13 for mine. I like the fact that the AR unit will give gyro compensated nose steering. Dan.
@@HornetFlyer perfect. I am using a xicoy lg controller as well. Enjoy the build!
@@FlyWithFrank I lost my nose gear door servo yesterday Frank. Bad luck or the servo can't handle a 2s lipo.
@@HornetFlyer oh man so sorry to hear. Mine is still kicking so far. Will update if it fails too
Frank - I purchased a Turnigy Receiver Controlled switch like you mention in your video to control the light on the landing gear. I have wired with a single battery per the diagram. With both jumpers in place, my led does work from my gear switch but in the wrong direction. The light is on when the gear is up and off when the gear is down. Can't fix that because the servo and switch are set to work the gear properly. So I need the light to work in the reverse direction. If I remove the jumper for "on" the light comes on or if I remove the jumper for "off" the light is off. But in these two cases the transmitter switch has no impact at all on the state of the light. If I remove both jumpers I get nothing. What am I missing? Should not one of the jumper positions allow me to reverse the light coming on in the opposite switch position so the light comes on when the gear comes down and goes off when the gear goes up? Thanks for any help!
Are you able to assign a separate channel to the light switch, reverse it as needed and then slave that to the gear channel? I had 16 channels to play with so this is what I did
@@FlyWithFrank Maybe will need to check. I thought the jumpers would allow the high/low position within the switch to be reversed depending upon the jumpers used? Do you understand the jumper diagram on the switch and instruction sheet and what they actually do?
@@FlyWithFrank Can do that. Then no need for a switch at all. Light gets power through the receiver if you use up another channel just to reverse the signal
@@FlyWithFrank I have gear assigned to channel 5 and the turnigy switch assigned to channel 7. Both work using the transmitter switches assigned. I then used a program mix with gear as master and turnigy switch as slave. Works just fine. Until - I turn the transmitter and receiver off then back on again. The switches work but the program mix does not. I have to reset the program mix every time I turn the system on and off. Something about the Turnigy switch is a problem. Don' t know how it works for you.
I have tried several combinations of separate channels then mixed. Same channel on a y harness. No harness and no mix just trying to get the switch to work on a toggle. I can get all of these to work. But, when I power off the receiver and power it on again the switch does not work at all. If I unplug the switch from the receiver and plug it back in again while the receiver has power then all combinations work just fine again. Nothing works if I power off the receiver. Any thoughts?
Thanks for the great video , do you know what voltage the servos can take
Bananahobby recommends max 7.4v. I am running mine on 2s lipo voltage so max 8.4v and they seem ok so far. The only one I have had an issue with is the nose door servo. It got hot because it was binding on the foam when gear door was closed. So check that it I not obstructed when gear door closes fully. Fixed that and no issues so far.
@@FlyWithFrank
Thanks frank I have got the t45 aero foam turbine version from austars
I too am Going with lg 15 gear controller are you able to send me your settings for that controller thanks 😊
@@FlyWithFrank hi buddy I’m having problems with my xicoy lgc 15 controller, with the brakes I have one side that just fades away and when it does connect it’s very erratic are you able to tell me what your settings are on your lgc 15 I pretty much have the same set up as you do , thanks in advance
@@robvonk8634 Oh man you are just a little late :(. I sold my T45 so I no longer have access to the settings. But I will be getting another and setting it up. Will let you know then
Quick Question, You mentioned the landing gear battery and the 2 twin battery packs are 2S, BUT you did not mention if they are LIPO or LIFE. Can you please let us know. I am setting up mine now and don't want to burn up any modules. LOL. Thanks a million!
I use a 2S lipo. Banana hobby recommends
@@FlyWithFrank Thanks and also thanks for the heads up on the front servo. Did you change out the main gear motors with the ones Ralph sent out or fly it with the original motors?
@@LOSCABOSLIFE I still have the original ones. Haven't had issues but it's on my plate to move to the new ones they sent
Hi Frank. You say that the CG point is 178 mm. But in the manual they say 168mm. Is there a reason why you set the CG point at 178 mm
Just started at 178 for maiden and move back as needed
@@FlyWithFrank Thank you Frank. I couldn't understand that the plane was so heavy in the nose, since I have the same set-up as you. and Thanks for some great videos.
20:12 is that a Freewing F18 in the background?
No sir. That is a giant Skymaster twin 110mm edf F-18. Videos of it on the channel here
How do you think it would do on a grass field?
I think short manicured grass will not be a problem at all.
one other comment it is not good to run your turbine for extended time on ground it can lead to over heating and damaged your bearings.
Hi everyone, anyone here using kingtech K102 G4 for this jet?
Frank are you part mexican by any chance?? You sound like a mexican american when you speak. As a matter of fact you sound like Oscar de la Hoya when you talk!😄👍
