2025 High speed Challenge

Can we submit another entry with the same plane? I hit 111mph a couple days after the run I sent, I need to try and cling to 2nd place

Yup! It’s perfectly legal by all means!

Yeah, I want to see you give it the works!.....I found the secret to my crashes on launch with the radjet..You have to give it just enough throttle to get it in the air but I was giving it too much to the torque roll would just whip it over before I could get up speed.

The really good fliers might just let it fly inverted, or continue the roll back to upright or change the launch to start inverted. Can't say, I ain't that good. Never had a torque roll issue either, come to think of it. Half power works. Or point it straight up, like a heli

In the speed game, you need a small value of exponential (5-10%) to correct for errors. Having a large value adds a couple of .10 th's to the reaction time to get the control surface to move the same distance.
Go get you radio and look at the curves say at 5% and say 40% to get the same deflection. I flew at 5% and my Jedi son always flew with no exponential.

That’s crazy 😆. But it also depends on how much control throws you have. The Radjet uses a ton of throws for the Elevator, and a lot of aileron is needed to counter torque roll.

That makes the difference on what height you can fly and how smooth you are. In essence, you are always playing catchup with large displacements making it unsafe. If your approach is yank and bank, it won't work. It's like NASCAR..
As far as your torque, you haven't reviewed the dynamic balance methods used by racers.

Looking at your plane, did you cover the gap between your control surfaces with something. That doesn't help stability and extra drag?

The best way to get a top speed(vert) is to use the Split S approach. If you have major deflections rather than small, that is additional drag and very high stress on the airframe.

@Houndpup Rc , I hit 162 with the Funjet today 😁. Video coming soon.

 

[Mr Man]

But the wingtip blew off my Radjet during a high speed dive, and it blew to pieces midair. Thankfully I was able to find the motor, battery, and what was left of the airframe, but I lost my GPS 😓 Now I realize that I pushed it a bit too hard. 😂

Yeah, that's why in my next video (That will be coming out tomorrow) I barely cleared the trees and came straight back towards me! 😂 (I am trying to use high rates for landing but it still needs a LOT of throws and speed to fly good! LOL)

Yup! You can use as many planes and runs as you want as long as you have a video! (BTW I passed you a couple days ago and you are in third now...@Patriot Rc is itching to pass you too!😂)

Talk about short lived glory! 😂 😂 😂

I am going to take the radjet out again tomorrow!!!!

You were pushing the legal limits! 😂 😂 😂

What’s up guys! I’m hosting a High Speed Challenge, and as you can guess by the title — it’s all about SPEEEED! Here’s what you need to enter: A fast airplane. Doesn’t matter if it’s a jet, warbird, pylon racer — as long as it’s fast, it counts. Some way to track your speed. You can use an RID...

Nice 👍
