I have those too, but they can slide forward and damage the canopy because they're thinner than stock. I wrapped a few turns of 1/2 inch electrical tape around the wire end of the lipo and covered the tape with large shrink tubing. That solved the problem.

I guess it does make more sense to change the connector on the heli instead of the batteries. Is the XT60 connector the defacto standard nowadays? Is there any advantage to the banana connectors?

Most batteries under 3000mah seem to have the XT60. And yes, it is easier to change the ESC connector once than change all your batteries.

take two zip ties and lay then in the battery cage just like the battery lays and then wrap them around and zip them as tight as you can. this leaves a portion of the tie strap bowed in the cage and when you pop a battery in there it provides a nice spring like action and they fit nice and snug. no tape needed.

My problem is one of my lipos is the stock one so I was forced to mod the batteries instead of the cage.

But if you're only using the one type of lipo this makes sense.

Couple of questions if anyone can give me a hand. My CP has seemed to have lost its power or motor spools down quickly. Starts good, runs for 1-2 minutes then slowly dies. Land it, throttle off, wait 1 minute, starts up and repeats. With other battery it lacks top end power or bogs out with any big pitch increase. I think its the motor crapping out. I am putting out 12.50V from ESC.
Its been so long since I have had a brushed motor, I forgot if this is how they act when they are getting bad.
Second question, with my ball links disconnected and testing gyro recovery or servo recovery, they do not move smooth, they kind of twitch back to center.
If I move the sticks then let go of the sticks, the servos slowly tick back to center. They don't move smoothly or very fast back to center. Of course I'm comparing this to my 450 so it could be perfectly normal and I just don't know it.
As a side note, my Ball links were so tight they were causing major binding. I don't know if they are all like this but if they are that has to be a big factor in the servo stripping issues.
Thanks for your help.

The behaviour of your motor is normal for brushed motors when they get older.
Buy a new one or better: Convert to brushless

What is wrong with my Master CP???

I don't understand. This thing is like flying a sack of stones. It barely gets off the ground, and when it does, the response is so slow and sluggish that there is no way anyone could ever do even the mildest 3D. Not that I would, because I can't - but it would be nice to just fly it without spending the next few days repairing it or waiting for parts. I don't know how to explain it. I'm used to the fast responses of the smaller helicopters, but I also fly the big helicopters in Phoenix (SIM) snd know how they should behave. My Master CP literally flies like it has rocks tied to the skids. Does anyone have any idea what this could be? Any help would be appreciated.

Hello!
Sounds like a servo is stripped. MasterCP servos are known to be ... bad (I'd use another word, but that'd be rude)...

Take the servos apart and check that the gears are good. Search this forum, there are a number of replacement recommendations (Hitec, futaba to name two).

Got any setup details, videos, pics?
Mine certainly lifts off at a rate of knots, I've seen other people doing mild 3d just fine. Seems like a setup issue.

What's the pitch? If it's too low, it won't get much lift.
What expo/dr's in tx? If you have too much travel reduction (on pitch) or too much expo in the d/r setup, it'll be REAL slow.

Sounds like not enough pitch tho.

Cool, I appreciate that. Let me look at this stuff. I'm using someone else's setup file for a Master CP. I run Deviation on my Devo 8s and it's an .ini file. Although I messed around with it because I didn't like the negative pitch on the first page setting. I probably messed it up, because I don't understand it enough yet to...well....understand it. But I'm trying! I really am. Thank you.
