[NSRCA-discussion] Use Two ESC's?

[Ronald Van Putte]

I have an off-the-wall question that I don't have the answer to.   
Somebody please tell me the answer.

A young local modeler has an electric-powered airplane whose motor  
puts out 1200 watts.  He has 5S lipo batteries that will handle the  
load.  In a ground test, the maximum current was 71 amps,  He had  
tried a 45 amp and a 60 amp ESC and they failed.  Hence the reason  
for the ground test and confirmation that he needed an ESC with a  
higher amp capacity.

I went looking at BP Hobbies for one of their inexpensive BP ESCs  
with an 80 amp capacity and they no longer sell them.  Other high amp  
ESCs are $100+

Here's the question:  Can he put two 40 watt ESCs in parallel?  Both  
would go to the throttle channel via a Y-adapter and the motor  
connections would be similarly Yed together.

I was also thinking of having him use a 6S battery pack and limit the  
throttle to 60 amps, but I'm not sure he has the room for the battery  
pack.
