Model Forum / Radio Controlled / Helicopters / November 20086EXH setup on Heli-max axe cp
Does anyone know what setings I should use for the 6EXH? I have : Axe cp with heli-max hm4000 gyro, EF C12 ESC and still useing the 3n1 board for the main motor. Still using helimax reciver. If I unplug the orange wire one chan 5 and plug the remote gain from the gyro the 3n1 pulses the main motor. but it works fine if I leave the orange wire pluged in. I can Live with that but I would love to use the remote gain without having to buy a new esc for the main motor. Any help would be greatly apreshated. > Does anyone know what setings I should use for the 6EXH? > [quoted text clipped - 9 lines] > > Any help would be greatly apreshated. OK I got it flying....

Give us an idea of what's going on and I'm sure you'll get some responses. Good luck & Fly Safe, Steve R. > What problems to you think you're having?

What should my th be at 0 pitch ? What should it be when hovering? I can hover at about 2feet but if I want to go up to 5 feet it goes up but will not holed there it ether keeps climbing or goes back down. I am flying in my living room. Thanks > > What problems to you think you're having? Give us an idea of what's >> going on and I'm sure you'll get some responses. [quoted text clipped - 12 lines] > > Thanks The rule of thumnb that I used when setting up my leccy heli (Piccolo cp) was this: If you want to hover at mid stick then set the pitch to about +5degrees and usually you will need about 75% throttle at that point Starting points for pitch (when learning): Bottom stick approx -3degrees Mid stick +5degrees Top stick +13degrees That is linear 16degrees of movement so the heli should move predictably when you move the pitch stick. Throttle should be ramped up quickly on an leccy heli, this is because leccy motors are most efficient between 70% and 80% of max rpm: Bottom stick 0% Mid stick 75% (set with the 'hover throttle' menu on the 6EXH) Top stick 100% With the 6EXH it doesn't have proper pitch and throttle curves (you can only set the end points). The best way to setup the heli is this: 1/ First set the heli up mechanically (set all radio adjustments to default: ATV, EPA, hover throttle knob to mid point etc.) 2/ Set the pitch/throttle to mid stick and adjust the pitch servo so that its output arm is sat at 90degrees to the output linkage. Move the arm one tooth on the output spline if you have to, or swap it to the other side and use a new arm cut to fit but get it right. 3/ Adjust the swashplate linkages to get them nicely lined up before touching the rotor head linkages to set your mid stick pitch e.g. +5degrees 4/ Now you can play about with the ATV settings on each channel to set the top and bottom points for pitch and throttle After you can hover easily and safely then play with those settings to enable 'idle up' and 'throttle hold' modes on the radio. For the moment set these modes to INH ie. turn them off. I can't remember where I got this how to setup a heli info from; so kudos to whoever put it down first (it might be Beav, but my memory and the original post is long gone).  SignatureChris Thanks Chris, I'm going to try this right now and will let you know ..... Hello Everyone. Well I tryed it and it works better than what I had. It still will not hold at a serten hight. It will hover at 2 feet now but if I want to bring it up some lets say 4 feet it goes up but it keeps going up. Is this normal ? Well I'm geting board of just hovering. I can hover nose out, nose left, and nose right. I think I'm going to practice nose out today. > Hello Everyone. > Well I tryed it and it works better than what I had.

Yes this is normal, the pitch/throttle does not control the height of the Heli merely the vertical thrust. You push up a bit to get it to climb and then bring the stick back down to settle into the hover again. If the Heli really is continuing on up even after you have brought the stick back a bit then land and check your head linkages, it sounds as if one is sticking and stopping the blades from returning to a lower pitch setting. Check this but first unplug or un-mesh the motor so that you can work safely on the head... check for smooth operation of the pitch servo and the rotor head connected and by hand with NO binding what so ever! > Well I'm geting board of just hovering.

Seems my stock brushed motor turned it self to a brush less, oh well at list I got about 30 or so flights out of it. I just ordered the HDX300 3800kv and a 30 amp ESC. 13t and 14t pinions. New main shaft bearings Cant wait till they get here. If anyone needs a 3n1 board for the axe cp let me know if you want to trade. > > What problems to you think you're having?
