LRP Speedbird Corsair (HK Funfighter) thrust angle

My nee unflown LRP Speedbird Corsair (appears to be a repainted HK Funfighter) has no downthrust. Thrust angle seems to to be up/right?
Can this be correct?

Possibly. Since its a low wing plane, it might need a little up thrust to counteract the strong down pitch from the higher mounted motor. How much up thrust? A degree or 2? There should be 4-5 degrees of right built in.

Cannot measure it. It's way more to the right as it is up.
So, if the angle to the right is 4 to 5 degrees, the up angle will be no more than 1 1/2 degrees.
I'll give it a shot the next calm Saturday/Sunday morning.
If she is well balanced she is going to fly anyway.

Fatal crash at first flight.

She didn't fly. Almost no control authority on elevator. She climbed a bit and went straight into the ground and disintegrated.
