DAVE BOXX Posted December 1, 2024 Share Posted December 1, 2024 Hi. I recently bought a Protech Alpha 2 in a job lot. I now need to purchase an Electronic speed controller for it. The one recommended on the box doesn't appear to be around now. (Not surprising) it states a Pro 35 to be used. Am I right in assuming a Pro 35 would have been a 35 Amp ESC? If, or if not, can anyone recommend a suitable ESC for this model. The battery is a 7.2v 1700mAh. Many thanks Dave Quote Link to comment Share on other sites More sharing options...
John Lee Posted December 2, 2024 Share Posted December 2, 2024 (edited) That's an old, probably about 2005-2010 model and I strongly suspect that it will still have in it the brushed motor that was originally used. There were many similar models produced at the time - there was a glut of them based around a common plastic fuselage and rebranded for different markets. The original was a 35amp brushed ESC which I have found online in mainland Europe Link but any similar brushed ESC would be suitable. A model boat or car retailer may be your best bet for brushed ESC's as brushed motors are still in common use in those vehicles. A brushless conversion is the other option, a quick search should find you suitable suggestions. Just spotted these which should be suitable & a few spares!

DAVE BOXX Posted December 2, 2024 Author Share Posted December 2, 2024 Thank you John. That's set me on the right path. I know what I'm looking for now. Regards Dave Quote Link to comment Share on other sites More sharing options...
Frank Skilbeck Posted December 3, 2024 Share Posted December 3, 2024 Be a bit careful with the car/boat ones, off is usually centre stick and moving the stick up for forward and down for reverse, could be useful for short landings, but maybe not! 😉 Quote Link to comment Share on other sites More sharing options...
