HELP ! MMP + Spektrum RX = cutting out ?

[kingdomracer]

I guess I should've been more specific. I was thinking instead of using the 7950TH to switch to my 7955TG which isn't HV. In that case would I still need an external BEC on 2s? And is it ok to put say 3 x 4600uf 10v caps in series to be closer (well actually way over) to BrianG recommended 10,000uf 10v? Thanks BrianG for a reply.

i actually had problems with a similiar servo.Not the hitec 7955tg,but the hobbico ct170,or cs170,anyway basically the same servo per the specs.So i would say no. BEC should solve your problems.Buy the cc bec pro so we can get some feedback on it.I've been concidering one.

You buy Hobbico servos and use the word cheesy in your other post
And please post help according to a person's application. I'm using a 2s setup why would I want a CC BEC PRO that doesn't even make sense. Like I said I'll wait for an answer from BrianG, thank you!

It's safe to run the 7955TG on 2S unregulated lipo. It's the same servo as the 7954SH but with titanium gears instead of steel gears.

No thats a 7950TG.... A 7955TG is a 6V servo...

Indeed. That's what's on the box. But the 7955TG can have 2S unregulated lipo without problems. Ask all the nitro guys. They run all run 2S lipo's with 7955TG servo's without any problems.

I mailed Hitec about it and it's true. The 7954SH is a 7955TG under the HV serie, but with steel gears and cheaper. And you don't lose your warranty if you run the 7955TG unregulated ;-) HITEC FTW :D

Just give that baby a lipo 2S lipo and it will be faster than ever :D If you don't feel safe about it, use the search in the nitro section of RC tech. (sry rc monster, but they have very big nitro section. NP to remove the last sentence if this isn't allowed).

We have tested the HS-7955 with 7.4V lipo packs and have not had any adverse problems. Many of our team drivers/pilots have been doing this for some time now. The spec sheets will probably not change, as they were written in 2007, way before we did actual testing with the higher voltages.

At 7.4V, the torque is 387oz/in and the speed is .13sec.
