Glitching is itching...

[Hickoryhead]

Ok I got all the stuff I need from Mike for the rest of my E-Revo project. I put most of it together tonight. I have to still put the UBEC in but everything else is in place. I put a receiver pack in place of the UBEC for now just to test. The throttle works fine in forward and reverse. There are no brakes. I am running a 1950\7 turn with a MM on 2 2s2p 6000 mah run in serious. The receiver and radio is a spektrum. The problem is there are no brakes and if I turn the wheels the throttle goes wild. It can be sitting still and turn the wheels and all heck breaks loose. Glitching and reaving up. I need to install the UBEC still but is there a problem I am missing? I mounted the MM directly on the G2R frame where the 2nd steering servo usually sits. I bolted it straight to the frame. I mounted the receiver to the empty side of the Emaxx transmission motor mount opposite the 1950. It’s strange for the steering to cause the glitching. It won’t glitch just sitting. I have not run it farther than across my living room but what’s up? Will the UBEC fix all? I know the receiver and radio are fine. I pulled them off another RC. No glitching there. Any ideas?

Does it glitch if you move it further away from the truck? Move 10ft away and see if it works. Have you tried re binding?

Glitching shouldn't b an issue with 2.4ghz, but here's something you might want to strongly consider: swap the positions of the MM and receiver. Generally you don't want the receiver close to the motor like that, and if it's mounted to the same plate as the motor, then that could be the problem.

OK I found the problem. It’s the servo. Before I start moving everything around I pulled the servo BEC out of the receiver. I replaced it with an extra servo I had laying around. No problem what so ever. Everything works. The servo I pulled out was a Blue Bird BMS-630MG Super Torque. Any issues with these in the past? This is the first time using it so I might have received it bad from the guy I bought it through. Any thoughts???

Sounds like a simple solution to me.... Pitch the POS $18 servo and replace it with a real one and your in business. Bluebird sucks IMO. Never had any luck with them.

I put the UBEC in and no problems yet. I will change out the servo though. Thanks

The only trouble with the BlueBird servos is that you CANT stall them or they'll burn up. You must set the EPA so they don't try to extend beyond any mechanical steering locks.
