Help! FT Tiny trainer fuselage not fitting freely into the RC motor version nose.

[Karthik1130]

I have cut the plans from 5mm depron sheet. when I try to fit the fuselage inside the RC motor version nose, it doesn't go freely, rather it's very tight and doesn't go inside.

What could be the reason? This happened in two of my builds. please help!

It might be because 5mm is a little thicker than Dollar Tree foam board. I think that’s 3/16”, which is about 4.78mm. That might be enough to make it tight.

Thanks a lot for your help! Is there any way to solve this issue? and , more over I took it for maiden flight under calm weather with zero wind, with 2S 850mAh lipo battery, A2212 2200kV motor, 30A ESC and 6 inch triblade propeller.
It was a complete success. I built this in order to learn landing.
But everytime, I overshoot the runway by coming in high speed and couldn't get the correct view angle to land the airplane. Thus I drop the thrust to zero suddenly and crash landed the airplane.

Try sanding the power pod to make it narrower. If that doesn't work, you will need to rebuild the power pod slightly narrower.

For future builds, you could try scaling the printed plans by 104.6%. Everything should fit well then.

For landings, the most common mistake is to start your approach too high and too close to the runway. If you do that, then you need to descend quickly which increases your speed. Instead, start descending while you’re turning to make your approach so that you’re already low when you reach the beginning of the runway.

Good luck!

and don't drop your speed too much until after the final turn, or gravity will consume you.
field size can sometimes make landings more difficult.

thanks a lot, definitely I will carry out.

yeah sure, field size plays a critical role.

How you arrived at 104.6%? could you share me

5/4.78, so the width of your foam divided by the width of the Dollar Tree foam board. You might want to sanity check that though.
