Im in need of changing my esc capacitor (2.1mf) but cant find anything of similar value. Closest I can find is 1.5mf. Im assuming the initial punch wont be as great. Anybody with any knowledge know if this will be OK? I dont want to risk it and pop my ESC.

2.2 is the closest normal value

Where can I find one with that value? Which manufacturer produces something like that?

Your esc manufacturer should sell replacement caps..

try and search this....2.1uf 16v...

Go to a Radioshack or online at Mouser.

Any Audio/Video store has a repair center and will have the cap you're looking for. It's also where I get all my shrink tubing, they have every size imaginable.

Just make sure you get a low ESR cap... Normal caps may end up damaging your ESC.
