RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes
Hi All
Quick update on my progress with the Conta Drive De Ja Vu. I now have 29 flights and as of today's changes finally getting that solid locked in feeling. My C/G is 27.5 MAC with .2 positive wing. I have now removed all the Rudder flare and both stab SFG's. I have reduced my "Normal" rudder throw to a very low 35% with a 45% Expo. Stall turn rudder is only 60% with 80% expo. I am using the 22x18 prop with the 10.15 gears @ 82 amps and on windy days I am using the 22x20 prop on the same gear set@ 88 amps. all at sea level basically. I have three mixes two conditions and one switchable dual rate:
Mixes
1. Throttle to down elevetor for vertical down lines
2. Rudder to Aileron for provose roll in both directions
3. Right rudder to up elevator in right knife edge only
Conditions
1. Snap
2. Taxi
Dual rate
1. Rudder for stall turn
I may end up with a "spin" condition as I am not satisfied with with the second 21/2 turn spin as it is "winding up" with not a lot of nose deflection any suggestions on this would be welcome. All the above is for P-13 and I am pretty sure I will need a F13 specific set up once I get further into flying that sequence.
Regards
Dick
