Hi Jon,
Thanks for the update. Bummer about your painted cowl. I painted the cowl on my Joker only to have all the paint peel off (I was using Lusterkote, but it was a 1/2 used can about 4 years old); so I monokoted the cowl and sealed it with some clear epoxy on the seams/edges. Worked fine, but it was a bit tedious. I've painted a lot of airplanes over the past 35 years and while I love a nice painted finish, Monokote can be applied with excellent results. There are pros and cons to both, but I like being able to cover inside (I paint in my garage) anytime I want for as long as I want and no smell.
The 12x11 on your Webra has to be a bit 'underpropped'. I've run lots of Hanno SPecials and prefer the 12.5x11 or 13x10 APC props for best performance. The 12x12 works well and is very quiet, but not the best choice when the weather gets hot unless you increase the nitro content of your fuel. Is the Webra .80 ABC or ringed or some or variation. I've run several Bully engines (Webras with different head/pump/modified carb) 1.20s and 1.45s. They are all ringed. Out of the box, the low end was too rich on all of them. Break in was slow, but after about a gallon of fuel I could fly a complete FAI sequence with confidence, after that I continued to lean in the high speed needle for another few gallons. I run my engines pretty rich. Once the Webra is broken in you probably won't adjust it much for 1,000 flights or so!!!
Happy flying,
Will
