JR NEA300 Speed Control - Blown Capacitor

I am finally getting around to trying to repair my stock speed
control that came with my Voyager E Heli . I have switched to a brushless setup
but thought I might use the stock motor/speed control on a plank or
something (what's the stock motor equivalent to - Speed 580 ??).
Anyway, I had a capacitor to blow on the speed controller and I want
to replace the cap. Problem is that I'm not sure of the value since
to old part is toast. If someone can look inside the NEA-300H
controller it would be a big help. Looking at the controller with
the power board facing down (board with battery and motor wires) and
the power wires to the right there are four small cube capacitors
across the fron edge of the power board. Three large tothe right and
one small on the left. I need the value of the center large
capacitor which is C3 (second cap from the right. It might say
something like 157 10V or 156 35V . It may take a magnifying glass
and some light to see due to the CPU board blocking the view.
Thanks for any help you can offer.
