As long as the batteries are all healthy and the harness is well made, I just don't see the problem you've described ever happening. If I do run into a battery that starts showing a state of over or under charge, I'll likely just toss it; these 1s batteries are not very expensive.

Well thats the other good thing about the in series charge,at the end or during the charge you can see the volts of every cell ,no need to play with multi meters all the time,just quick and convenient.

I hate to complain but I am definitely needing some help.
I have the 2801 BnF...
it spins counter clockwise constantly in both 3 and 6a modes...

VERY twitchy for my taste,

and the throttle runs... in TH and in norm I cant stop it without maintaining pressure on the stick.
Quite a chore to do all of that and still unplug these little batt connectors to try and kill it.

I am on my way out until this afternoon and then I will re check my settings per Toms settings, but that is what I did initially, I will also read the fixes again... and any additional advice offered, thanx.

First does the tail motor run?? Is the rotor on the shaft tight??

Hi, I've just read every page of this thread, and I'm convinced. Was going for a mcpx but, this heli does seem to have the advantage. Now the problem I'm having is deciding which tx to go for, being a newbie and coming from only ever flying an old blade cx2 and more recently a solo pro 2, I don't have much experiance. I was just wondering, what advantages would a devo 8 give me over a devo 6? The genius cp being a 6 channel heli.. also I was thinking of future proofing by going for the devo 8? (+ the devo 8 does look proper sexy!) Thanks guys..

Tom, are you sure about this? I just turned that pot across its entire range while watching the servo horns and swash. The servos definitely have more range of travel when that pot is turned fully clockwise.

In flight, with it fully CCW, it behaves exactly as if I'd enabled my D/R settings. With that pot fully CW, the Genius is like an angry little hornet. I gave it full reverse ELE on the stick and the heli was perpendicular to the ground and flying straight back at my face before the girly scream had fully escaped my mouth.

It is possible that the Devo 8 may have a longer range (bigger aerial). This will be useful if you get a larger Walkera heli or use a Walkera receiver in a larger heli or plane.

I wonder whether the same applies to both your 2801 and Devo versions?

I don't want to mess with mine yet,,but it sounds like you are correct from it's actions..

I would go with the 8 if you have the money.. But Then I'm only going by what I have read..

I just tried mine. Turning the pot doesn't do anything.
Which RX version are you checking this one? The 2801 or Devo?

I'm in the process of transferring everything over to the new frame. I'll check it later this afternoon when I get it back together.

It's the Devo; the 2801 is currently disassembled.

Odd that you don't see any change. I don't see much change from 0 - 50% on mine but, with the cyclic stick locked fully to one corner, I can see the servos change position when I go from 50% to 100% on that pot.

Edit: Actually, the change in travel seems pretty linear across the range of the pot. It's just not as large of a change as what I see when I adjust the extent pots on my other receivers. It very definitely affects flight, tho!

Please note the correct position of the pots. The image on the Helipal website is wrong. Apparently Walkera made a mistake as well.

OK I turned on the ADJ pot on the RX and turned off my D/R & EXP.
The pot does adjust servo travel.
It must be a servo extent pot. I don't know if turning a delay pot would
also move the servos. I will check now on my Walkera 4G6V 3 axis.

Crank that thing fully CW and try some 3d, Tom. I've set mine back down to the mid point. With it fully CW, I was damn near doing unintentional 3d and scaring the hell out of everyone in the room.
