No. Tam's recommedations are very conservative. I suppose there may be situations where it might make a difference but I've seen these pumps put in all sorts of locations and it doesn't seem to make much difference. Take a look at one of his pumps in my KingCat....close to lots of stuff and wires running everywhere with no problems.

Just make sure you do a good range test while switching the pump on/off.

FYI, I might suggest a seperate battery. It only takes a size AAA 6 cell/720 mah for a days worth of flying. Keeps the smoke system completely separate from the other electrics.
