2075 problem

[Metalhead Matt]

Here's one for ya Traxxas guys. I bought 2 2075 servos. One for my E maxx, one for my T Maxx. The 2075 won't work in the T Maxx. No power getting to it(doesn't do anything). Both trucks have the same stock receiver. Both servos work in the E maxx. Any other servo I plug into the T Maxx works(2055, 2018, futaba s9304). What gives? Same radio, same receiver, but the servo only works in one of them. The E Maxx is the original,(8-9 years old) and the T Maxx is the 2.5(4-5 years old). I'm stumped.

I'm note sure about the voltage that old T-Maxx has but it could be just too small.
did you check the connections in your T-Maxx?
is it just one servo that doesn't work in T-Maxx or both? and also did the old servos work in your T-Maxx?

These questions are all answered in the first post.

yeah I must miss read it a bit.

First thing I would do is compare the output voltage on the the 2 receivers in their respective rigs.

Will do, robmob. Be right back. The E is at 6.54 with a trx 1100 pack. The t is at 6.43 with a 1400 rx pack. They measure the same at the rx's as they do directly at the batteries(haven't been charged for a while).

Got me stumped.

If other servos work and clearly there is enough juice to power the servo, it should work. It doesn't take any more voltage to power a 2075 than a 2055.

Odd.

Electric gremlins seem to haunt me. This is weird. Looks like the 9304 is going in. Though it's weaker, the 2055 sounds like it's full of sand, but it's not. I couldn't see a clear problem with it, but it probably has a broken bushing or something. It cogs in one direction, too. The 9304 will have to work for now. Glad I picked up some light tires/wheels off of ebay for it.
