Not in the pic is a Turbotronics UBEC I got off E-Bay. It's mounted where the double sided tape is and Rx lead is running right behind tranny then parallel to ESC lead into Rx box.
It's a stock 3905 with the single motor plate on it and power is a Ammo 36-56-2600 inrunner, MM esc, Turbotronics UBEC.
I 1st had it setup with the Mamba bec working and it worked great up to about 100ft and started to glitch. I twisted motor leads and that did nothing. Then I added the UBEC and had same result. I've swithed in two different crystal sets and tried a RC18 Rx that seemd a little better but not much. I should clarify this is all happening on a single 6-cell battery because I'm waiting on my Deans plugs to wire in the 14 cells.
I'm buying a used Losi DSM for $40 shipped and hope it cures it but i'll wait to see.
