Got a question about the new receivers can a receiver be faulty ? I mean I know it could be faulty if it doesn't bind or power up . But can a receiver burn out a servo ? Pulling at straws but I had to ask . Race tomorrow and still haven't found anything wrong with the car or end points .
The other possibility is that you've bound the receiver in SSR mode, which some servos could potentially think is a far far left signal, and burn out because they're not able to turn that far. I'd hope that servos are protected from doing that sort of thing, but I guess it's possible.

I think it would be tough for the receiver to burn out a servo as long as you're not applying High Voltage (i.e. either not through a BEC, or with a BEC set to 7.4v) to a standard voltage servo. The receiver can only pass on the voltage that it gets itself, it doesn't have any circuitry to change the voltage.

In terms of race time, this means 36 minutes, plus testing, which was about the same.

So I ended up buying this transmitter on Thursday. For the most part it's really nice and priced perfectly for my pocket. The only drawback I will say is the required AAA batteries.
I only used it Thursday evening of putting in 6 models in the memory and going through the screens to get familiar with. I raced with it first time yesterday (4-11pm with 4-heats and 2-mains and maybe 4 practice sessions) and the battery warning just beeped.
If it's going to take a few months to get a Lipo, I may have to try the Eneloops

So I think everyone (including me) is missing a trick here... The MT-44 does require lower voltage, so a 4-cell NiMH pack wouldn't work... but what about a 3 x AA pack?
I just took the battery cover off mine, to take a look at the space where the Sanwa LiPo that I ordered (from Japan) will go, and I noticed that there is some foam padding around the AAA holder in the base. If you remove this, there is, I think, enough space for a 3 x AA pack like this: http://www.frys.com/product/2965525. I might pick one up and see if I can make it work, because this will give a pretty long run time I'd have thought, and I have plenty of AA Eneloops. I'm interested to see how much it impacts weight as well.
I've ordered the Sanwa LiPo already, so I'll probably end up using that, but I thought this was an interesting idea anyway.

Does anyone know if the small wheel from the M12 will the MT44?
