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.

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 remember reading something in the manual that said an analog servo could/would be ruined by running in SSR mode.

Analog servos can even be ruined in SHR mode I believe. If @Ofna2005 is using analog servos though, I'd be very surprised. The response is so slow that there is almost no point in using anything other than an entry level radio!

I've just went through a race day with one set of Eneloops Pro (1000 mAh), and they still indicate like 60% capacity. Since I also have a spare set, I'm happy, because this means that I don't need the lipo. The chance that I would run out of power is zero.

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.

Just got this today, it should be a better option than AAA's at this stage

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

Any feed back on how long it lasts?

I'm hoping that Amain will come out with bigger capacity 1s soon...

My jcon wheel from my MT4 fits my MT44 (same wheel fits the M12) so it will fit but the offset was slightly different on the new radio. Only slightly further out so not an issue.

5 min. I'll try another set of batteries and see how long they last. The one I used at first may have old

And yeah, on Amain's web site the MY44 does say "supports 1s lipo"
