The firewall is a fiberglass reinforced plywood that the motor mounts onto. It must be extremely stiff or else vibrations from the motor can cause it to flex which will cause the vibrations to grow until either something breaks or the throttle is reduced. Additionally the firewall must be att...
If the Bushwacker does not survive the flight attempts, I recommend building a simple disposable/sacrificial plane that is easily repaired or replaced. And if it protects the motor/prop when crashed, that's an added bonus. There are several I have experience with, I'll be happy to show you...
For this plane, I used 2 motors that would provide roughly 860g of thrust with a 10x4.7 propeller (1720g total) and draw about 12Amps each.(Info/ Recommended propeller found on motor manufacturers website). Using this equation,(Flight Time(min)=Battery Capacity(Ah)/Motor Amp Draw(Amperes...
Easiest way to calculate gear ratio and motor size. Very accurate with easy to understand info from your rc heli and it’s drive train. Spac3Ghost , 2024/08/21 Please update the cell voltage For the headspeed calculator, the voltage should be adjustable or made to 3.7v or 3.8 as op...
At the end of the 2 hour training program, you'll have the skills to build and/or convert a glider to electric power, estimate its performance with a motor calculator, program the Electronic Speed Controller with the proper settings with your PC, program your radio properly, and be able ...

We can now add these known figures into Thrust Calculator. By the fact that you can verify thrust it becomes possible, to estimate the general power of the airplane in advance. This will give you more knowledge about your plane and the power characteristics to make your first flight less ...
In SC performances ** all results are for WOT ** (Static) thrust is for plane-speed = 0 Next version, I will label "Static thrust" instead of "Thrust" ** Pitch speed is a "theoretical" speed in flight (zero thrust roughly) When I make tests, it is on a bench Regards Louis Jul...
Second, wing loading has a lot to do with the "floatiness" of a plane, so perhaps you just need relatively smaller wings, or more weight on board, for any given plane. The expense will be an inherently faster flying plane. I'm not sure that's what you want in an enclosed area tho...
If you look some posts above, you will find another flying wing I´ve built and you will see, that it is no problem to balance CG. Now I plan to mount the motor behind the fuselage, to reduce noise and get less cross section / resistance. Tom ...
