Information on Large ESC's:

Plettenberg page on ESC's and Price List linked from Predator 37 page. This is the one it mentions for Predator 'future 40.160H; Spin 200' but it does not say what model of Predator.

This from a posting;

"I belive special versions of Plettenberg Predator can handle 15kw of power, combine this with 15s Lipo and new Jeti SPIN 200A, one motor-prop-ESC, best efficiency in both cost and performance

This from a posting;

Even better would be to use the new Predator with Jeti SPIN300 and 15s Lipo EVO cells to get maximum performance.http://www.hacker-motoren.de/images/...7-Web38u39.pdf

Multiple Motors:

Question: If you want to fly a plane with 2 electric motors ... do you then also need 2 speed controls or can you hook up one esc to both the motors ? (and anything you should keep in mind when doing this ? like maybe make one motor turn clockwise and the other one counter clockwise or something ?)

Answer: 2 motors (brushless) will require 2 speed controllers. There are a few that have been (claim) successful in using one speed controller for two motors, but there are ramifications and side effects that can rear up. Both props can spin in the same direction and there isnt anything special to keep in mind. The two speed controllers controller leads will be hooked up to a Y harness and then plugged into the RX. One battery can be used, but the voltage will need to be higher to run both and the amp rating (on the battery) should be high enough to handle the current.

Ideas:

Consider making the controller's aluminum heat sink an integral part of the rear leg. ={2 functions from 1 part)
