Dick,
Thanks for clearing up the question on the servo's. The manal says 9 servo's total. That is why I thought it needed 2 servo's for the rudder. 4 servo's ailerons, 2 servo's elevator 1 servo rudder, and 1 servo throttle that makes for a total of 8 servo's. I went to the seagull wed page and they call the Bling 50 a Harrier 50 and it says only 8 servo's on their web page. So 8 servo's it will be.
You are right about the carb on the Brillelli. I will have to do some cutting on the cowl and I am a little worried about that part. The cowl looks to be very narrow. I am getting a Pitts style muffler fot the Brillelli, that will help some.
