I'm using an OS .41 as mentioned earlier, but considering a bit bigger for the altitude at which I'm flying (9,000 feet).

bbbair - with the motor at 90 degrees and the carbs down, where's the muffler?

Missileman mentioned "holes for your fuel lines" (emphasis on plural). How many of those are there? I've also got a clever idea of where to put the glow extension....

mscic-RCU - do you have any info on the scale tailskid you made? That's the only mod I'm considering as a "must" and would be really interested to see how you did it and how you changed the rudder too. However, I have thought of a solution to the directional control problems. As soon as I saw the "tailskid" on the plans I knew it was going to difficult at best on the ground. So, I dreamed up a system to have differential brakes attached to the rudder servo. When I get 'er done, I'll put some pix up and let you know if the reality is as good as the dream. [8D]

Thanks!
