Default KO Pro Pro EX10 Helios

I just bought the EX10 Helios from a friend and I am tired of buying AA's. Anyone have a solution for a Lipo Pack? What kind of plug does it take?

There are several that fit in the case. You may have to reverse the pins in the plug and put the black one in the center and the red one one the outside. You will have to make an adapter for charging after you do this.

Stormer Hobbies has a Reedy branded lipo that is made for the Helios/Eurus radios. You have to make up a fairly simple wiring harness to charge it.

Ballistic Batteries has a nice lipo with its own specific charger...Fairly expensive; but nice.

do you guys know what kind of plug it takes? is it Futaba, JR, what kind of a connection? I can always take a mini airsoft battery and make one, I just don't know what kind of plug it takes. Also what happens if I plug it in with reversed Polarity?

Reverse polarity will fry the power switch...Thant is if you are lucky enough it stops there!!!

yup ProTek Pack for mine. the 2300mah lasts around a month or so on a single charge racing 2-3 times a week.

It came with instructions on witch way to put the pins in the connecter and witch way to plug it in..

i went a step further and broke out the exacto blade and marked witch side the positive wire should be on.. (my helios the pos wire is on the pin closest to the back of the radio)

Looks like proteks pack is a 2800 now

Makes sense it will last a bit longer.

Default VR adjustment

A friend of mine turned on the VR setting on my Helios / JR Z1 radio and the car felt "better". Couldnt explain what it was exactly, but the car seemed mire tame. I read the manual to see what exactly the VR adjustment is, but I'm even more confused. Can anybody explain this in laymens terms?

It adjusts the steering and throttle potetiometers in relation to the CPU to compensate for their wear over time. Do it twice a month and your radio will always feel the same from run to run.

They're on the heavy side, but Eneloop AA's are incredible rechargeable NiMH cells. They have very little self-discharge. Don't charge them through the radio, though.

Related question to the LiPo pack. I have a checkpoint LiPo balancer. What type of connector/adapter would I need in order to charge the 3s transmitter pack?

The charge lead polarity simply needs to be reversed. All I do is switch the leads going into the charger. Most chargers have a reverse polarity alarm (check to make sure your's does) so if you forget to switch it back when you charge your next pack you won't do any damage.

Regarding the balancer, if you're talking about this balancer (http://www.amainhobbies.com/product_...-Poly-Balancer) I can't help you.
