When I bought the CC from Tower last year, it was on sale for 175 bucks. It came with the rs-540 sh td022613 motors installed with the higher reduction gear set installed. The boat ran slooow ! I installed the other unmarked motors the CC came with along with the lower reduction ratio gears. Much faster, but on the second run one of the motors caught fire ! Trash them junk motors ! I installed some stock e-Maxx titans [23t] at @ 20 bucks ea. and opened up the windshield and ducted the incoming airstream to the motors [ I'll post pix on rc/flix].
At that time I got the Storm and haven't ran the CC much since.
After reading your post I re-examined the CC motor to shaft clearance and you're right, not enough clearance for the available ready-made cooling coils; I'm not sure that the silicone jackets would fit any better, but now I've decided not to go to 2x7 cells until I can come up with better cooling, as the current setup runs fairly hot as it is. I beleive that a single direct drive 700sc with a jeti and 2x7 cells is the way to go. More work initially, but probably far less de-bugging later. Hand-fabbing the motor mount will be a chore, but after that hurdle the rest should be easy, such as shortening and supporting the shaft and finding the correct prop.

I ran the Storm this morning and it is hauling butt ! I run 2x7 cell 3300 mah sc sport paks from OE, 27.99 ea. !

If you need documentation on the CC, I think Megatech's website has an Adobe pdf. If unavailable I can scan & e-mail my documentation that came with the CC. If you want to focus on the Storm, I'll send the modding details that make mine handle & fly.
