Hello All,
Well the Econocoat projct is progressing quite nicely. Its time to lay out the electronics. Due to the fact that I put a Power up 480 sport in for a motor I need to put more weight in the behind the cg point. So I was thinking of putting the electronics there. My question is will the 40amp ESC get to hot if its inside the plane, instead of under the cowling?
Thanks

Linear or switched BEC?
How you going to prop it?
How many/kind of servos?
It all makes a difference.
That motor is massive overkill.
If you are 'coting' it everywhere that will tend to put relatively more weight back than front. Depends on the covering plan.
You may not be as far off as you think.

Hello flydiver,
I belive the ESC is linear not switched (its a HURD 40amp ESC).
I picked up a few props. I want to use a Master Screw 3 blade 10x7. That should give me about 50-55 oz of thrust at 33 amps. The servos are Corona's and I wil be using 2-6 of them depending on which wing I am using at the time. I am building this plane with the idea of being able to switch the wing out, depending on the flying I want to do. Right now I don't have much flying time in so on the first wing I just covered it with econocoat. No Ailerons or flaps. The second wing will have carbon fiber added, along with both Ailerons and flaps. The reason I went with this motor is I plan on putting floats on eventually. So I wanted enough power to get it in the air off the water.

If a linear BEC (probably 3A) you are fine up to likely 4 servos.
If you put more servos in place you best go to a aftermarket 3A Switched BEC.
An ESC with a 3A switched BEC could probably handle 6 servos.
I suspect Coronas are not particularly thrifty servos. No personal experience though, just a hunch based on reports.
