Re: speed controller for fisher price

The victor is the only thing that comes to mind that would handle both motors unless you build your own. If you want it to be forward only and controlled by a servo actuated pot, then it is actually fairly easy to build your own. It probably isn't too much harder to build your own with reverse and pwm input. How many cells do you plan to run? A Novak Super Rooster would probably do it but it is just as much as a victor. Actually, my recommendation would be to get a used (but with guarantee) Novak EVX off of eBay and run two stick pack for 14.4 volts. That's your best option since that ESC is made for two batteries and two motors and you'll get awesome performance. Should be able to get it for about $60-$90

What problems were you having with the nitro engine? Was it an ofna engine? They are notorious for air leaks. I've had alot of troubles with mine as well (TRX Pro .15). I was almost ready to sell the thing. But then I finally figured it out and now it starts every time and runs great.

Nitro engines can be quite reliable with the proper tuning and starting procedures. Let me know fi you need any help if you want to stay with nitro.

PS. I'm going to be starting on a weedwhacker powered RC simply for purposes of reliability.
