More BLUEPANTS pics to keep you interested.

I built mine to the plan 4 or 5 years ago now with a little right rudder on it to keep it tight on the lines, the plan shows zero rudder and no out thrust, but to me it felt very light on the lines, so I added right thrust on the engine and it's much better.
After out last session with them a month ago a friend who has the yellow one with an ED Racer had a fly of it and suggested it felt rather nervous and that the C of G needed to be further forward, so last week I pulled the motor out and glued 30g of lead in the front under where the engine goes.
I'm not a very good CL pilot, but do enjoy flying them now and then, so with a little luck that should fix it. The C of G is now about 25 to 30cm behind the leading edge as a guide for you.
