I have 3 kits I am slowly collecting parts for and...

The shore line looks very unforgiving. One mistake and certain destruction.

RE: Adding caps to esc???

That makes the most sense of anything i've heard yet.

Cool ,
That para board is the bomb, just a little expensive because I would also need 5 or 6 of the 'T plug to JST' adaper cables too. So all in all about $30 + shipping.
