Stability problem
 

My ego 60when leaving the ground seems to be very unstable almost uncontrolable. I have checked all the linkages, everthing seems to be right. is there anyway to colm it down it seems that the control inputs are super sensative. the only thing not acording to the set up in the manual is instead of 100+& - travel adjustment on the elevator,aileron & pitch I had to set them at 125 in order to get 10+ pitch, also someone told me that it seemed like the head speed was to fast (rpm) he said that this coud cause the over sensative control inputs, does anyone know if this is true.

Touchy heli
 

Try some exponential on elevator and aileron cyclic if your radio has it.Make sure it is + 25 to 30 %.This will make it less sensitive around neutral. High head speed will definately make it touchy.Hard to tell unless you have a tach.Should be around 1500 to 1600 rpm in hover. Tim.

Do make sure which radio you're using, before setting exponential.
For JRs, the above info is correct. For Futaba, you want - 25-30% expo.
(Not fun to find out you've got it the wrong way... trust me.)
Not sure about other makes of radios... but you want whichever way makes
the cyclic have less movement around center stick, and more at extreme stick positions.

Not a heli expert at all... just wanted to make sure you got the expo right, if you use it ;)

FOR ANYONE WHO'ABLE TO HELP ME IS THE NEXUS A GOOD PURCHASE HELI?

Valentin,

My Nexus has been good to me - reasonably! (It's my first chopper.) If I had it to do again, though, I'd probably look at a good 60, (the Raptor seems to be held in high regard).

One of my buddies at the field also flies a Nexus, and constantly has to recheck his tracking. (I've found at least one web site that lists this as an inherent problem with the Nexus.)

My Nexus developed some slop in the head, (after 1 1/2 gallons of fuel), that I managed to track down: the pitch lever pivot pin had worn the outer edges of the chassis hole it passes through. This allowed, at hover, abrupt changes in collective - which were a fun learning experience!

If you're new at helis, let me suggest that - whichever bird you decide on - the second-best training aid you can get is the CoPilot, IMHO. Correctly set, and calibrated, it won't interfere with your cyclic control while learning - but it could save you considerable expense!

Thanks for the help I have found the problem, it was a bad gyro, it was switching back and forth from normal to reverse so I sent it back for a replacement

Graeme, thanks !!!

what kind of tachometer are you using
