Mini CP spins out of the box

[Jake P]

Just picked up a mini CP from Wow and they flew it in front of me and it flies fine. Now that i'm home on my own Devo 8S it spins like crazy making it impossible to fly. I'm a newb. Can anyone help? I'm guessing there's some settings i've got to change, but I called Wow and they told me to send an email and they'd get back to me in 2 days. I wanna fly it now!

Did they use the same transmitter? If the rudder gyro is turned down all the way, it will spin... Check that setting. On my 2801, it's under GYRHLD ---> GYROSENS. I'm sure it's different on the devo, but it may be named something similar.

On the -8: (same for -8S)
1). Touch the rounded-square heli model on the right side.
2). Touch 'Gyro Sensor'
3). Make sure that 'Normal Mode' is set > 50%, more like 75% is good.
4). Although I haven't noticed a difference, the manual talks about putting the 'MIX' switch in position '1' with '0' being all the way up, '2' all the way down and '1' in the middle, in addition to setting the gyro to less than 50% for adjustment mode so just to be sure that isn't part of the problem, make sure the 'MIX' switch which is above the right stick, is all the way up in position '0'.

Do you have the Mini-CP manual? If so, it would be good to go through the TX settings to make sure they are at least what it says in the manual to start with.

A quick question, the tail rotor is spinning, right? If you hold it in your hand while you spool up the throttle and if you give it left or right rudder, do you feel it trying to turn in those directions?

You should also be able to (while it's spooled up in your hand) turn the heli counter-clockwise and feel the tail try to work against you. You'll also hear the tail rotor buzzing like an angry bee.

Seems overly simple to mention, but are all the switches on the tx in the correct position? This happened to me once last week. Bound up with new battery, then tried to throttle up, but it just spun on the ground. Turned out my Mix switch was not in the normal "0" position but instead on position "1". Once I flipped that back to 0 it flew just fine. It is very difficult to notice the difference just to look at it, but I now check those switches before every flight. On a side note, I also have to make sure the battery door on the tx is closed. It doesn't latch very tightly, so can swing open and drop the battery pack out -- not related to your problem, but annoying nonetheless.

Thanks guys! I think I got it, but the right side servo seems to be locked up now. I wonder if it's a setting or if it's from one one my 10 crashes. This heli is super fun!

Make sure your tail boom isn't pushed in too far.

but the right side servo seems to be locked up now.

I had that happen twice.

Here's what I did:
1). Disconnect the servo from the RX
2). Remove the servo from the frame
3). Remove the two screws from the bottom of the servo
4). Pop the top off the servo, the part that the drive gear pokes through
5). Jiggle the gears a bit but don't remove any. You can check for stripped teeth but you won't find any.
6). Put the cover back on the servo
7). Reinstall the screws holding the servo back, middle and top cover sections together.
8). Plug servo cable back into RX.
9). Disconnect main and tail motors.
10). Attach battery to RX and test operation of servos.

From there, after reassembling everything you had to take apart to get the servo out, go fly. :)

After you make sure it is flight worthy, but not pushing it too hard, it would be a good idea to modify the servo horns using the 'Servo Saver' mod but you don't have to, if you like disassembling that servo 'cause it's just going to happen again. ;)

[jonbailie]

Be careful with that last method, and use a 'precise' grip if you can. Those gears are small and sometimes hard to get back into place if they fall out. I usually try not to let any fall out while I mess with them. It's also a good idea just to stock up on a few servos if you crash frequently. They are only small plastic gears, so they tend to break off teeth after certain crashes. Set up and get used to throttle hold on your transmitter. That may save a few servos in the future.

Do the servo saver mod! I wish I had done it in the first place. It cost me 50$ for 3 servos. I crashed alot. Also be careful when you open the servo case. Sometimes the rod that holds the gears in place will fall out and will never be seen again! And itsmillertime had said to make sure the tail boom isnt pushed into the frame too far. He should have told you why. Its because it will jam into the servo . It happened to him.

[Heli-opolis]

Its because it will jam into the servo .

What will jam into the servo? The tail boom is inside the frame and the servo is outside, where is there interference?

I'm looking at mine and can't see where or how one would affect the other. Can you explain?

[mescalinedream]

You will have to ask itsmillertime to explain. It happened to him.

[jonbailie]

I've never had that happen. The boom should not go through the frame, as it has a little stop inside it.

[mescalinedream]

I posted that about the tail boom jamming into the servo without even looking. Itsmillertime had posted thats what had happened to him. Now that I am looking at it, there is no way the boom can mess with the servo arm. I have no idea why he posted that. it doesnt make sense. Maybe the tail wires were in the way of the servo arm because he pushed the boom in too far? Maybe itsmillertime just got confused or something.

[itsmillertime0]

Just saw these posts. The tail boom did not contact the servo arm it just pushed in on the center of the servo which made it seize up.
