I love my lipo and i heartily recommend it over NIMH... I have done some duration testing showing that it takes 9h to discharge the lipos to 11.1 volt from a fully charged 2200mah pack... (and i got woken up at stupid o clock like 16 hours after starting the test by the LVA because i had forgotten to turn the battery off... Well longer then equivalent capacity NiMHs last according to test on the URC forum...)

Mods wise, you need to remove the battery tray, simple matter of removing some screws, snipping a few wires and soldering on your fave connector... I used deans myself... I got my battery on ebay for like 8 bucks... add anothter 20 cent in connectors (i use myself some knockoff deans which work well:P)

Only one thing to this "reset to factory defaults". It needn't work for everybody, because there is test for raw value 901 and for example my full right-steer has only value 865 (but I can change it to arbitrary value now by modifying firmware ).

HAX:P So how much of the FW have "we" decoded now?

Well, I know wellquin, didn't buy there, but guys I know did, haven't heard about problems. Good price, but that free shipping is I suppose the cheapest one w/o tracking, so maybe longer delivery. Could take a week, but also 20 or more days. Depends on much factors.

Yes, thank you for the amendment. But the tested raw value 901 isn't the same for all radios. My Eurgle GT3B has a wheel full-right raw value of 857 and the reset works. Maybe it depends on production series - using a slightly different pots, who knows.

Maybe I would be a little careful about using 3S LiPos. I have found some few notices about this, that some guys used the 3S and it fried the radio. The electronics of the radio uses 5V from a voltage stabiliser. Fully charged LiPo is somewhere close to 13V, so the 8V difference turns to excessive heat, which could damage the stabiliser. Better to look for a 2S LiPo and mod the firmware to the correct voltage warning value. As psx said to me, this warning voltage can be set from 7V.

Well if i fry it i'll be sure to let you guys know:P but so far it's all good And as i have said i have litterally run a pack through it from the full 12.6ish volts all the way down to 9 (because i was being dumb as a pole:P) and it all still seems to be working fine...

Now LiFePo might be a better idea granted, but my charger is massivly oldskool and cant handle those And besides i have always run my Tx's of non rechargable batteries specifically because they get higher voltages and lipo isnt much more "voltie" then those are...

That frying isn't often, but it happens time to time - I only wanted ya folks to know about it. The LiFe is a good option. Using 3S LiFe could be OK, using a 2S LiFe could I think need to replace the voltage stabiliser for a low-drop one.

Well as i said i expect stuff to be fine, if i roast the voltage regulator i probably just install a new (and overkill) one , and maybe slam a fan on the thing:P

That said, i did read several good reviews about the seller, so hopefully i ended up with nothing worse than maybe longer wait time i'd say

As to the battery, I was considering some cheap NiMH, i mean, they're cheaper than LiPo generally. But I just realized that HobbyKing carries some really cheap low capacity LiPos compared to some Sanyo ones I was considering. What's you guys' opinion? Cheap LiPo or Expensive NiMH? I saw that GT3B came with charging port so I can charge it with battery in it with my iCharger maybe? I'd guess to do the same with LiPo i'll need to do some more modifications to the unit?



Would you mind sharing the seller's name Braaap?

This voltage regulater on the left top in the photo that is used on the 2.4 modual runs to hot wonder if it would be a good idea to swap it out for a more beefy model.

might be an option, another one would be standing it up a bit more (assuming there's room for such an option) or somehow rigging up some kind of venting to see if there's a way of getting some airflow going...

Or just fitting a fan to it;P (brute force solution FOR THE LULZ!)

That's what I was talking about. There is an option to mod the receiver for a 2S LiPo tu cut down the excessive heat produced by the stabiliser.

I am on delay, should have received the kit yesterday, but Thursday is the final day now. So some toy to play over weekend
Hail to Highlands!
