Hey does anybody have any suggestions on why my blade is not gaining in altitude it has a lot of flights on it! I thaught I might have wore out the moters so I replaced them with stock units. It has new outter and inner shafts and new blades. And I also bought a new Battery charged it up and still no altitude only gets off the ground about a foot! Could the 3 in 1 controller be bad now? Any suggestions would be great!

well sense thats the only thing left that control`s power to the motors that you havent changed, i`d say thats the ticket
sense that is the speed control

maddog,

I think BAD400 has a good idea there. But I would ask you to do this simple test, new inner and shafts or not. Often guys use the blue motor heat sink. That heat sink if not put on properly pushs against the main shaft colume which then pushes the motors out towards the nose. When this happens the motors are off center and can be crammed into the the lower gears. Now even if you DONT have the heat sink give your heli this test. Hold the lower blade. Then with your finger slowly turn the upper blades and shaft 360 degrees about 3 times. You are looking for any resistance or binding. Once that step is done then do the same with the lower blade. This will be a little more difficult because the upper blade is in your way. Again your looking for any binding or resistance. If this test shows you nothing then I would even check the new battery. Charge it again and get a volt meter and see what you have. That 7.4 volt battery comes up to about 8.3 volts on a good charge. If that proves again to be all in spec then you might as BAD 400 said have a bad 3-1 controller. I have never seen two motors wear out at once.

A question or two, did this just happen? Are you using the stock CX2 charger? Have you been flying fine then one day with NO WARNING it just wont come up? Please provide more information please. A new controller is like $60.00 as I recall so lets really look at this before you sink some bucks in there.

I am using the stock charger just put the new battery in a friends new CX3 and got ten minuts out of it !So we now know its not the Battery or charger. and Im not runnin a blue heat sink yet thats somthing on the list of mods. And yes the problem just kinda came up it had been runnin fine for Oh at least 60 flights with no problem thats why I thuaght it to be motor probs. I will look at the shafts agian and do what you said and check for any binding Thanks

Here is just a shot in the dark.

Trim the throttle trim up. When I was messing with my mCX I noticed that when the throttle trim was all the way down it would only get like two to three feet in the air. When it was higher it went higher.

Hope this works,
Kyle

Some have had similiar problems with the scale fuselages and found there linkages going from the servos to the swash were rubbing on the fuselage... I'am sure you checked, but thought I'd throw that out there just in case...

Did you take any components apart like the lower rotor head or anything when you installed the fuselage ? It might be something simple as a component not being installed correctly.

I think I just found the problem I started retracing my steps And remebered that I installed lights and around that time I started having problems. with altitude and duration . I just reassembled the chopper cause I tore it all down couldnt find any thing wrong so when I reassembled it I didnt hook the lights back up just flew it for a ten minut flight with all the altitude that I could want! Thanks everyone for your thaughts I think it was just those F*#@ing LIGHTS!![sm=48_48.gif]
