I always liked the idea of CL Speed, but I really like to fly models and speed flyers don't generally log much airtime.

Toad, it had a canopy. Look at the first shot. There are some remains of a flat plastic canopy that was in a slot where a rudder usually lives. On this model I put the rudder on the bottom and the canopy on the top.

Graham, I used a bladder made of KT20 tubing and had it stowed in an aluminum cigar tube.

I just wiped off the dust and weighed the airframe and it is 5 ounces. For a really quick first lap, I think 5 ounces ought to include the engine. But at that weight the takeoff could be exciting dealing with the torque.
