nice one chris

fv432 might have to pick your brains again at some stage just started a new topic in other builds

chris

will have a look and ask away chris

i was thinking of getting a rx-18 unit but after reading some reviews about it they seem to overheat but the rx-14 board seems to be better what do you think

chris

for 25$ and a 7$ cooling fan, you can probably do no harm w/rx18. I have four. The three that came to me in good working order are still going strong. One even tows a ~15lb tank (proper gearing required)

thanks xrad i have my eye on a rx-18 with wireing going cheap hope i can get it

chris

RX18 uses theoretically better drive FETs than RX14, the problem is cooling. Definitely take the lid off the RX18, make some holes in it and fit a fan, and assuming standard motors i'd also fit a 3Afuse in line with each motor - fuses work out a lot cheaper than boards.

thanks tankie for your info i will do as you say

chris

i have a stug 3 which i havent started yet it has a new metal gearbox and rx-18 was thinking of putting them in the KT as funds are a bit short at the moment and i could replace them later in the stug so will the gearbox fit the KT

chris

Stug has shorter shaft length as far as I know. It is not easy to add length to the shaft. Look for HL tiger or JP gearbox...might be closer fit.
