Hi Mike,

I've used heat shrink tubing (available from Radioshack) for motor sleeves
on A6 and other long motor classes. I've never had plastic straws work like
Gary. They always seem to cut the motor. I'll bring some heat shrink to
the flying session this Friday in Catonsville. We can also talk about other
possible areas for improvement on your A6.
