mCPX - 130X - nCPX shakes? How to clean Blade linear servos
Have you ever experienced the famous "shakes" when you hover your micro helicopter, being that any chopper that uses linear servos (Blade mCPX, 130X, mSR, nano CPX, Walkera 120D02, ...)?
Well there are a few solutions to this problem, but the most common, and the one that helped me out almost always is...
Linear servos basically work with a wiper sliding on a metal strip. This friction causes some grit to deposit both on the wiper and the strip. When this happens the signal is not clear anymore and the 3 in 1 will struggle to center the servo, causing the shakes.
You might have heard someone saying: "just clean them!" and maybe you are a bit afraid of opening up such a tiny and expensive part of your heli. Well, fear no more, this article is for you!
|First thing to do is to remove the canopy and expose the electronics|
|Then go ahead and with a pin disconnect the three servo connectors|
|In my case I took the 3 in 1 off too, but there is no need for that, just carefully unscrew the servos from the frame|
