Keep going. Good channel, I’m highly convinced if you had a proper futaba or Sanwa radio it would solve a lot of your issues. 100mph is not a challenge anymore for almost all r/cs it boils down to quality parts and experience. Keep it up! New sub.
Thanks for the kind words. Always cheers me up and helps with motivation.
I know there are better controllers out there but I alway have to keep in mind on whether those watching my content can afford things. Saying that whether I can afford them. 😂 But if i find one at a decent price then for sure I'll pick one up. Thank you so much for the information as sometimes I do forget that there are other brands out there. 😉👌 And thanks so much for the sub. Much appreciated! Have an awesome day! 😊😊😊👍🏼
Keep pushing. You will achieve the results desired. Great channel!
Yeah will keep pushing. Thanks to all of the great ideas I should have a much more successful next run. Plus the temps here are slowly increasing which means the track will be nice a sticky the next time. Thanks so much for watching and supporting our channel. Wishing you a fantastic day! 😊👌
Great run and no crash 👌 😂😂
Finally 😂😂👌
Hi John good run no crash To bad the tires didnt stick better .I like wl toys 124016 tires after the tread wears the better they grip . They will run 70 mph just did 69.5 mph with my snrc r3g belt drive today with 2s battery .Cant wait for my AK 917 RTR .D o you know when shipping will start thanks .
Yeah I honestly think the original tires will work. Just need to figure out the 120+ kph crash issue. Cars shipping very soon. Let me ask Rlaarlo again.
Great vid i would of been tempted to try foam tyres on road at side of drag strip, foams may work better👍
I don't know... I ordered a brand new carbon fiber ones just cause of carbon parts, the cool aero and the look of this car, but I don't want to regret for it.
For what I've seen in various video , it looks like it becomes pretty unstable over 100-120km swaying all the ways and loosing control.
Looks like something related to steering or the servo pulling some way at high speeds, but I am just guessing.
Even this kind of drone revs noise during accelerations is quite thrilling. However, the built looks solid and pretty good.
If I was you, I would try to run on normal asphalt. That one looks more slippery with that oily stream on top of it.
Mate. I will be honest with you. Like I am always as I know it's a lot of money. It is a great build quality car. Goes so fast. On high speed gearing and a subaru impreza shell i was power sliding on my small roof and it was so controllable. (should have been able too with high speed gearing.) And the 120+ kph i am convinced can be solved with either 2 tiny front wing flaps or removing the rear ones. I am testing soon. Twice i have crashed at 120+ kph and the only damage was the front wheel hub. Any other of my cars crash at that speed and I would need to brush it up with a dustpan and brush. Every time I work on I am smiling. Its great. And if I can find higher shock towers it will also rally. I am convinced of it. So if you believe me with only one thing this year then believe what I wrote. 300 for this car is bonkers cheap. Don't like it. Not conviced? Sell it for a profit. 😂😂🤣👌
@@JohnRobinsonRC That's really good to know mate. I really like this car and hope it's gonna get a great 1/10 scale platform for speedrunners. But well, yes.. sometimes it's easier to get attracted by a good looking sight, when it's the performance that matters. So, hope there is even substance in this nice rc model other than beauty.
Time for some upgraded electronics 😊
Didnt look/sound like the foams were gripping on the main track, motor sounds like its accelerating but the car isnt-maybe they arent suited to a rubberised surface. Maybe try a run on the clean concrete to the side of the main track??
John,why don't you just take two 2s batteries and run them in series to make 4s,that way you'll have more than one 4s battery. I know you may need to play about with the car,moving bits about so it fits and get the weight balance correct etc but just an idea mate.
Best of luck with the channel and I hope you,Colin and the rest of your family are well
Yes we are all well buddy. Hope you are keeping safe and well and the family?
Get this mate. Same day I recorded this. Got home. 3 x 4s batteries waiting for me... 😂 Typical.
Boy that still looked super-fast to me! My butt clinched up a couple of times when you got close to the wall lol. Hope you get to do another run with the 4 cell
What sh rating are your foams John? That thing absolutely roasts all four wheels at any serious throttle by the sounds of it! Looks like the surface out there was pretty slick somehow. Time for some softer compounds maybe?
No idea the sh rating i am afraid. No idea where the tires came from. I think the track was mega dusty and not warm enough to gain grip. However the weather has now turned and I think there is an awesome time in this car. Especially with the changes I will make. 😁😁
@@JohnRobinsonRC the track certainly didnt look sticky. A decent set of known brand soft foams probably wouldn't hurt either. Be fun to see what you do with it!
@@DanjaBis honestly mate. I think the original tires have it in them. It's just this crashing at 120+ kph that stops play... But got loads of solutions for the next run. 👌👌😁
I'm still waiting on someone to do a speed run where the car can actually reach the advertised speed.
Instead, there's so many vids showing the same thing. Unboxing and crashing
Yep for sure an issue. I had a few personal things to deal with but will try and test the car this weekend. 😊👍🏼
@@JohnRobinsonRC hope things get better for you! A few of your vids would have frustrated anyone when the car unfortunately ran into some issues
@@judybustamante9859 thanks mate. No worries about frustrating cars. I love trying to figure it out. Just new medication messed me up very badly. But getting better now. 😊👌
I know they were originally planning on shipping out this car on the 20th or people receiving it starting the 20th. But it looks like they still need to do some more work on it before release but I’d rather have everything all worked out before receiving mine whatever time they need to work on everything is fine with me even though I’ve been really awaiting this release from Rlaarlo.
Yeah I would have to agree. Either that or send a big HUGE bag of spare parts. 🤣🤣👍🏼
@@JohnRobinsonRC 😂🤣👍🏻
Clutch is a no go for speed hunters
Might be deceiving on video but the track appears quite slippery ?
Use the road,next to the track
Foams don't work on drag strips. The rubber on the track is too smooth & slick for foams. You need to get a set of medium compound rubber racing slicks(not drag slicks).
Great stuff. Thanks for the info. Was answering comments from the previous video where people were stating I should use foams. Sometimes I do things to show the results on my channel. I don't always know the answer myself until I test and usually half comments say one thing and the other half another. 😉 Have a lovely evening.
Meanwhile, it's almost MAY and no sign of pre-orders being shipped from Rlaarlo... how are we suppose to build and test for the speedrun competition next month?
I had confirmation & tracking number from Rlaarlo that my preordered Metal roller was sent on the 18th April, I ordered mine on the first day of the presale 15th March. I also ordered the carbon roller as well on 6th April but no confirmation yet on the one being sent yet.
All pre-ordered rollers that were among the first 500 had there's ships by April 20, as promised...and, because of some last-minutes changes, all pre-ordered RTRs that were among the first 500 had a slight delay, but they shipped by April 28. Anyone who ordered during March, but were not among the first 500, should have theirs shipped around May 3, and anyone who ordered during April should have their shipped around May 10. Those last two dates are according to the email I received from Rlaarlo 4 days ago.
Hello, with the motor that comes from the factory you can use 4s? I ask because there are many kv for 4s, it exceeds the 50,000 revolutions that these motors can withstand, thanks and good video
I'm running contact foams and I love em. They really stick to concrete. Just wish they made a larger diameter than 65mm
Yeah they are great. Was looking for them to run on the F1 car.... Nope. As you say 65mm. 🙄
they do. 1/8 foams from contact are available
Really. Wonder how I didn't find them? I'll search again. Thanks for the tip! 😊👌
@@JohnRobinsonRC yore welcome. They have 100 mm in diameter and a 1/8 bore,.i think 12mm
delightful vid maybe try on a harder surface
Yes but I don't have another area to do these speeds on my island... I think as the track warms up which it will now, that the grip will come to it. 😊👌
Loving these 917 vids John.. it's fascinating. The sound it makes when you kick in full throttle is brilliant!. Sucks about the slipping issues on this run, but it's still interesting. I notice that right alongside the drag strip there's a nice looking regular road.. have u tried running it on that to see what the traction's like?
What size contact foams are you guys using? They're expensive, and confusing to look at in store. Any info would be handy
John that track seems too shiny and slippery for foam tires from the video. Maybe you should use the sideway which seems like a better road for foams
Yeah problem is that that side had very bad holes. As the temp increases then the track will get much more slippery. I will go back to original tires and I think I solved the crashing issue. 😁👍🏼
Did they do any prep to the track before you ran??
Damm that thing Screams loud on full Throttle 😂
what foams are these;
If I were you I would try driving on the pavement right to the side of the track I guarantee you will have better traction on that then you wouldn't with all that rubber down on that track especially with foam tires
Would saucing the wheels help with traction or slow it down?
Actually the track is glued when an event is on. I was thinking of trying to try the track the Monday after. Either the car will grip or blow up into bits as they say the glue is strong! 😂😂😂
@@JohnRobinsonRC I'll look forward to the results of that vid, this is dedication to the community "I did this so you don't have to" 😂😂
I would think that saucing the foams is an excellent idea
hopefully you can get 100% traction and im sure you will get above and beyond 130km/h
Yeah for sure. Several solutions suggested to help plus the track is heating up meaning more grip so next time should be much better. 😉👌
Anyone ever try using a Gyro on the Steering?
Sounds like it was spinning up
Must be hard running on ice. Your videos are stressful.
You need some Pimp juice from AMain
hard to see but could you get permission to run on other side of the track "where those caravans were"?
looked more clean..i think rlaarlo should send you a new car with all the problems fixed umm version 1.0 customers version.. LOL
The WLTOYS 124019 SEEMED MUCH EASIER TO DRIVE, EVERYONE AND THEIR MOTHER GOT IT TO 100MPH, THIS THING IS GETTING DESTROYED BY EVERY RC CZcamsR AND IM YET TO SEE IT PASS 85MPH
Hard to argue with your assessment to be honest. For sure there is something happening at 75 MPH causing crashes.... 😞
@John Robinson RC RLAARLO to be honest with you, is the same with everyone else’s, something is happening as this is proving to be an unstable platform, please watch other people's video and if possible I would like to hear your input as im sure this is not caused by a lack of skill. Thanks again
@@jah-jah87 no for sure it's after 75 MPH that the front end looses grip. That's what has caused my crashes. I have seen two other videos with the front lifting up. I assumed too much downforce at the rear forcing the front too loft. So I have a solution and need to test it. 😊👌
@John Robinson RC RLAARLO You ever heard about the X0-1 ? Long story short its a forgotten platform that suffered the same syndrome as it wont track straight no matter what you do. It got ditched by the RC COMUNITY, loved only by fanboys and kept as shelfqueen as its not good for nothing else.
@@JohnRobinsonRC Hi m8, what foam tyres you recommend for this car?
Thanks
wltoys 201417 could run 190 to 250 kph on less than 4s. Must be the weight with all those lights and metal parts RLAARLO did.
15 grams in lights isn't going to slow it down
Topp.Brasil.
I’m thinking you have been infected with the speed.. lol.
Sounds like the diffs are slipping
I thought that think it has a slipper clutch though so could be that
@@Nathan-qt2zi tighten it down and try again
