Help! Controls are over sensitive!

[cainenglish]

Hiya. Newbie to the rc heli thing and seem to spend more time fixing the thing than even hovering it. My issue is that I go from neutral position on the servo's to maximum or minimum on the aeleron and elevator range of movement within 4-5mm of stick movement on the transmitter. I don't seem to have the same problem with the rudder. This seems SO difficult to learn on. I am using JR ES 375 servo's on the aeleron and elevator, and a Hitec HS 568H on the rudder. Here's the clincher( I think)...I cannabalised my old walkera 60 for the transmitter(WK0701) and receiver(WK701 7 Ch). Does anyone know how to decrease this sensitivity or am I flogging a dead horse and should buy a new transmitter/receiver etc due to compatability issues. I have a very helpful local hobby shop but am beginning to feel like a tool going back for spare parts every few days(no tto mention I bough the thing for a bit of stress relief lol). Cheers, Cain

umm, a walkera radio? is there expos to dial in? end point adjustment? dual rates/low rates? need some more info about the tx.

I would ditch the walkera tx/rx and get a decent computer radio. If you think you will want to stay in the hobby, you could drop the coin for a DX7. If you just want to fly and get going cheap, you could go on ebay and get a used 72 mhz radio cheap. I bought a Futaba EX6HP for less than a hundred bucks off ebay and it came with a couple of rx's and a bunch of servos. You need something you can dial in some expo with, a computer tx is the best way. You could look at your setup on the helicopter as well. Look at how you have your swash links installed on the servo horns. The farther out on the horn from the screw that holds the horn on, the faster the helicopter will respond. If you install the links closer in, it will tame the twitchiness, but at the expense of travel. In the end, a decent tx/rx will save you a bunch of heartburn.

It is typical rtf stuff, the only adjustment is a knob to change where the pitch comes on in the throttle curve and another knob for how much total pitch can be achieved.

Thanks Jason, I might swallow my pride and go have achat with the hobbyshop re transmitters etc. Cheers, Cain

Cainenglish,
before you run off to buy new gear may I suggest a few things?
1. Get a simulator first
2. See if there is someone local to you that can help you.

These two things are instrumental imho.

Its a sad fact that cheap helis - like cheap musical instruments - are the most difficult to setup and learn on. Even experienced pilots can find it impossible to satisfactorily control the RTF small helis. Having a decent radio certainly helps enormously as it gives you far more control over the radio input and changing pitch and throttle curves can make an uncontrollable beast into a flyable fun machine. So I say for anything over and above the co-axial rotor fun helis - get a decent radio if you think there;s half a chance of staying woth the hobby

I don't know anything about the Tx but maybe you can desensitize the thing by adjusting the link ratio. Look at the servo arm and see if you have any holes closer to the center and move the link there if so. The same servo movement will then give less swashplate movement.
