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

Heres some more information from the tower web site, they want to sell you a t6xas with standard 3004 servos, and two 3003 servos, so they must have tested it with these and work ok.
