Paul T,
I read parts of your build thread yesterday, and I know one thing for sure: You had a lot of fun building (and talking about) the BFs. A very entertaining thread with lots of useful information! I'm really looking forward to building mine. I will build in a few extra degrees of down thrust - thank you for the tip. And I have more or less decided to buy a .15 engine. They are so inexpensive that I could probably get a .10 later if I want to.

BW,
electric would - no doubt - be the easiest and most convenient way to do it. I can't remember seeing other glow powered gliders than the BF and the POC (not counting Gentle Ladies with Cox pods). The 100'' plane with a tiny glow engine will probably raise a few eyebrows at the field, and there is something about IC engines that attract me - although I can't say exactly what. I don't want to say that electrics are a bad choice, or that people flying electrics made the wrong choice, but to me there is something magic about the smoke, sound and smell of an IC engine.

Right now, when I close my eyes and look at my BF when it is finished, it will have a 15LA, 4 oz tank and a huge lump of lead up front. Blue fuselage and yellow wings with blue wingtips. I'll keep dreaming until it arrives in June, but this is how I picture it today.
The problem with an IC engine that I ran into was the long idle periods. The engine would dead stick every other fli8ght because you just could not open it up for an extended period of time. The 15 will probably do better but I just couldn't see adding weight.-BW
