Give it a tiny bit pitch up trim, just in case the CG is a bit forward. If you have dual rates, set it up for around 60% for the launch, then turn it off once flying. A couple of times it porpoised a lot after launch - really twitchy.

I launch mine underhanded, grasping it between the "canopy" and CG, and tossing it slightly nose high, though you may want to see how Tomas launched his in his video above.

I have really high, 3D-like throw rates, with high expo set on channels 1 and 2, so I can fly it smoothly when I'm not doing tail slide loops, cobras, and tail stands - it is very responsive. You're going to love this airplane.

That is the most difficult part of flying this plane for me!

I also usually launch mine with a click of up trim.

I think the cool thing about the thrust vectoring is that you instantly have control of plane. Normal parkjets with the motor on the back have to attain a little speed before the controls start working.

Successful maiden - - F22 now has 5 flights on her.

Not as fast as I had expected - using a APC 6x4 - - tried a 7x4 - amps were too high (22) and it did not seem that much quicker.

She sure does float nice when landing.

It should fly at least once

If you want more speed you need to go to a smaller prop not bigger. bigger will give you more vertical not speed. Try a 5 X 5

Smaller prop revs quicker therefore more airspeed, bigger prop pushes more air but at slower speed, so the bigger prop is better for 3D and vertical pull/hover.

EDF's runn very high revs and small props to get good airspeed

I use a 7x6 prop with a 1500kv motor.

It's quite good between torque and speed.

Ok - OK I am a dufas...!!!

This was my first time using a pusher setup.

Guess what - - I had the propeller facing the wrong way.

Now that all is correct - this girl boogies - - Love it.

"Numbers face forwards", works for all applications both tractor and pusher.

Glad you got it sorted. And yes, these planes do boogy.
