I'm using - RC-expert Brushless Motor 3200KV (20-40) [link=http://www.rc-expert.com/product-upgrade.php?pid=32]The long thin one[/link]
RC-Expert aren't exactly known for BL motors but it's the one that came with it. This must be the prob, it's the only thing left to try!!!

Gord-
it bogs down very easily.
That could be the problem -too slow head speed meaning the tail isn't spinning up enough to stop it rotating. You might need a motor with more balls. Do you have any more specs of the BL motor you are using?
