| Subject: | Re: Stalling the TR-1 |
Hi Jeff!
Unfortunately I never had the chance to stall or to fly a TR-1, but for me, if
it was properly built and if it is within the CG limits, it seems to be a docile
aircraft with that rectangular and mid to low aspect ratio wing. The airfoil
is also known for a predictable behavior.
If you are interested in expanding your envelope, begin with a good weight and
balance. The aircraft should be configured from mid to FWD CG for the first stalls.
As you expand the envelope, you can start thinking on AFT CG tests.
If you dont have experience stalling high performance aircrafts, consider getting
proper training or getting someone with more experience to test it for you.
Select an airspace suitable for testing and define your altitude limits to start
the maneuver and to recover. Consider getting a parachute.
Begin the stall testing trimming at 1.3 to 1.5 Vs with Idle Power. Slow it down
with elevator only at no more than 1 kt/s and recover at a safe speed. Pay attention
to the aircraft tendencies and check controls (3 axis) effectiveness at
each 5 kt steps. Keep the ball centered! If all is ok, continue reducing the
recover speed progressive up to full stall.
If you feel confident, explore stalls in turn and accelerated and aft CG too.
Good luck, keep safe and have fun!
Fabricio.
