I just received the tiller today, (perfect timing with this snow storm!) and decided to update to a DX6 from the stock TX. I'm running the tiller from a BEC, and noticed that now when driving the Blizzard with a ST 2x12, that it cuts out...a lot! I have to accelerate very slowly, or it will cut off all power to the motors. Very annoying problem, I didn't have this problem at all with the stock tx. I'm running heavy duty 7.4 5000 MAH lipos, Titan motors, no idea what's causing it now because this setup worked great with the stock TX. And the tiller doesn't have to be on and powered in order for it to happen either, which is odd. Any ideas?

Probably need to get all RX and servos running off the BEC, the sabertooth only has a 1amp BEC. BEC to the RX and then remove the red pins from both sabertooth RX connectors.

Hmm, just made a new lead out of 14 gauge wire directly from the battery to the ST, no switch, BEC or lights connected. It's not cutting out on the bench anymore at least, hopefully this translates to actual running. So now the only way to turn it on and off is by plugging and unplugging, which is annoying- I guess the wimpy thin gauge wire on the stock switch harness was overwhelmed. So do most of you guys with BECs, lights and tillers run these from a spliced tap off the main leads?

I run all electronics off the BEC especially because of the 10kg servo for the snowblower it is very power hungry, I also run the tiller motor off of the BEC because I found the stock setup wasn't power full enough.
