To asnwer you question about prop pitch/speed/flutter...
This plane really isn't a speed plane and should be flown as such... Not saying it can't but it is a light plane and you'll feel it in the air... it feels like a funfly not a 1/4 scale CAP 232...
In saying that, it CAN be flown alot like a pattern plane too... clean flying and responsive.
You might also liken it to a 3D trainer... I've started to learn rolling circles with it... It's slow and easy and quickly recovers from a stall or inadvertant exit...
The plane has a channel built in the bottom of the fuse for a tuned pipe... an inverted Pitts might be tight... I had a YS 91 in it and if flew real well with lots of power, but I had some issues with YS engines and replaced it with a Saito 100.. all I can say it AWESOME.... beautiful combination...

Ok, now I'm starting to get interested in this one. I have a few more questions for you guys on this engine install and the airplane in general.
1. Did any YS 91 owners use an inverted pitts muffler, will it fit?
2. Can you use a prop greater than the 6 pitch that is recommended and get away with it, anyone had problems with flutter?
3. Here are the specs on the Futaba 3004 servos from the tower web site. This still makes me wonder if it will be OK to use the standard 3004's, they are close at: 44 oz, they say at least 50+ oz.
SPECS: Speed: 0.23 sec/60 degrees at 4.8V
0.19 sec/60 degrees at 6.0V
Torque: 44.3 ounces-inches (3.2kg-cm) at 4.8V
56.8 ounces-inches (4.1kg-cm) at 6.0V
Specs on 3001's that came with my 9CAP are the same, I thought they were stronger servos...........
4. Any modifications needed other than what is in the instructions?
5. Any complaints on this airplane from anyone?
Thanks,
WOOD
