How does one mount a water-jacketed motor in an Aquacraft Rio EP?
:confused2:
I neglected the 10-minute cool-down advice from Aquacraft @ http://www.aquacraftmodels.com/techsupport/aqub1800tech.html , and fried my stock ESC (fatal failure during run).
I am going to upgrade my Rio (http://www.hobzob.com/vehicles/view/p/rc/v/3574/i/rio ) to a low Kv brushless motor on a 60A ESC, just enough to drive that surface-piercing prop to put the Rio up on plane quickly, and get some long run times without any timeouts except to swap batteries. I plan to put a second water pickup to cool the ESC independently from the motor...but more about that in other postings, this thread is about how do you mount a brushless motor with a water jacket on in the Rio EP?
The stock Rio EP motor mount is a clamp about an inch/2.5cm wide: see attached photo from http://www.aquacraftmodels.com/boats/aqub1800-rio-ep/aqub1800ai01l-lg.jpg, which excludes any water-jacket for the width of the clamp. Water-jackets generally cover most the the length of the brushless motor, which doe not leave much to clamp (target motor is the GForce BL3650 Water-Cooled Brushless Boat Motor 2300KV (540L) from Value Hobby, but that motor only has 1.5cm of 'freeboard' outside of its integrated water jacket). The after-market mounts I see online appear to be for fiberglass boats.
:huh:
Photos of your water-cooled brushless motor installations would be much appreciated.
