Default Bec question

Does anyone know if it possible to use a airplane external BEC in a rc buggy. I know BECs(external) power the reciever from the esc batteries, but does it matter if its a plane, heli or quad external bec, if someone has done this, what brand did you use? Thanks for your input and comments.

1. Might be You get little higher current peaks in a RC car because of the steering servo could be working rather hard.
BEC in an ESC has max continues and max peak current specification so You have to loook at that.
But if the BEC can deliver 5-7 amp continues it should probably be OK in most cases (the servo has to be able to be used at the voltage the BEC will output or has been set to output).

2. Usually ESC for cars has proportinal brake and that is unusual for airplane ESCs, although many ESCs for airplanes has brakes (but not proportional brake).

3. Also, many car ESC has fan for better cooling on them, airplane ESC do not have that usually (but it can be a heat sink for better cooling).

4. Many car ESC is also waterproof.

5. ESC for car has usually reverse.

Do You have the ESC already? If yes what brand and model for the ESC is it?
What car/buggy is the ESC intended to be in (brand and model), how many LiPo cells are You going to use, what motor and what servo (brand and model) for stearing do You plan to use?
Personally I would use an ESC made for cars in a buggy so You get most of the features I mentioned above.

The only reason I can think of to use a separate BEC, on a buggy, is if you are planning on using a high voltage servo? Castle Creations CCBEC
