Hi all, have replaced the Eflite servos on my CX2 with Multiplex Nano servos (because they are red and look cool!? [8D])
When I first connected them all up, both servos were in reverse (forwards was backwards and left was right etc) so I fiddled with the reverse switches on my Tx until they were correct, now .............. my Q is, when you move your right stick up and down, how many servos move? On mine now both servos move, one pushes and the other pulls, am almost 100% this wasn't the case with the original servos?

Also .......... somewhere else I posted a photo of my heli with a very lightweight canopy from www.bladecx2.com, like this one:

I have completely trashed 2 of these in a week!!! They are excellent, and a lot lighter, but, unless you can fly and are NOT GOING TO CRASH, AT ALL, then stay away until you can, they break like egg shells!!!! The first one was no problem really, but I'd spent about 10 hours painting and applying a very intricate Union jack design to the second one [X(] and it broke like an egg within 2 minutes of me starting my heli, was outside, heli went up and came back down from about 2 feet, landed on it's skids but the canopy shattered, the first did much the same, but from about 60 feet up [8D]

Am going to try the Extreme clear canopy next, will report back.

Meanwhile, servo movement help required please!?

Many thanks!

Sorry to hear about the canopy problems....had similar issues with mine! Onto your servo question. On the stock CX2 these move independent of each other. Up and down or elevator will not or should not move when applying aileron. That's about all I know with regard to servo's. Have you got them plugged into the right ports on the 4in1?

Hi mate, thanks for that, yes definitely plugged into right places, did one at a time and made double sure it was right.

What I mean is that now if push the stick to go forward, both servos move to put the swash to forward or reverse, one arm goes up and other goes down, working with each other to increase the force moving the swash, only forwards and reverse though [&:]

My helli did that when it was new, but now it dosn't do it. So when you go forward the heli goes alittle sideways and not truely straight, like it did when it was new.

No, sorry you misunderstood, it flies great, just that instead of 1 servo pushing forward or pulling back, it now has both applying force, 1 pushing, 1 pulling, but side to side still 1 servo controls both movements, by pushing and pulling while the other stays still.

If I knew how to upload video..................

Yea thats what mine did new. Only forward or backwards.

Right, all sorted! [8D]

Had a good read through loads of similar posts, and I'd set mine up wrongly.

All I should have done in the first place was replace the servos, then once I'd seen they were reversed, all I needed to do was flip the switches on my Tx, No. 6 and 7, but instead I had flipped them all until it looked like it was working correctly, trying to save time not reading the manual ............. but those 5 minutes cost me my 10 hours of work on the canopy! []

Thanks for the help!

oooh - you flipped the throttle reversed too? - bet that was ugly! ouch!!

did it go the wrong way round, or did it zoom and shoot up as soon as the green light came on

if you are using the stock tx, i wouldn't be surprised what its doing - the stock radios are crap - the analog potentiometers 0 points wander, settings change depending on humidity, signal strength varies by whats rattling around loose inside the radio

we work so hard getting the heli right and half the time its the radio

one of the things that i was taught when learning rc airplanes way back when was the importance of single stick directions - a lot of the time we get unwanted heli motion cause we are not just adding one thing, say like rudder, and we goose the throttle too cause the radio isn't square to our thumbs or horizontally flat, or we get sideways as well as forward when we just wanted forward

just something to think about when you are wondering "why is it doing that?" - suspect the 'human interface device'
