Hi Guys
I Need help big time, this might take me a bit off time to explain but i will do my best to explain breifly.

I use a Futaba 3GR and i race boats all over the UK and Europe, the biggist problem i get it ESC.

The water cooled ESC's are very expensive, but the electric flight ones are a fraction of the price.

The best ones on the market are all for Electric flight, but they use 4 channel radio with a ratchet stick for the throttle.
This moves the full length of the servo throw, as all 3GR's have is sprung loaded throttle that sits at the center point.

Now this my question: how can i make the flight esc arm with the 3GR without having to use a
PiStix Adapter [link=http://www.offshoreelectrics.com/proddetail.php?prod=msw-pistix&cat=136]
in the boat

the 3GR has so many functions but i can't get any to arm with holding the throttle stick back.

So can anybody help ????

Cheers
Stephe

You need to use an ESC that's intended for RC car or boat use. Airplane speed controls are not designed to have their "off" position in the middle of the stick movement. That's why you have the difficulties you do. Short of using the adaptor, there isn't really a solution.
