Yes get better servo's. Heli's put a lot of stress on servo's and the 3001 are fine for a trainer aircraft but thats about it.

I went to Futabas' website and got their reason why you should not use the s3003 in helicopters, here's their quote;;;

Why are S3003/S3004 servos not to be used in helis?

Both the S3003 and S3004 use a direct drive potentiometer. What that means is the output gear is connected directly to the potentiometer. Since the output gear is connected directly to the pot it is very possible that vibration will damage the pot. This is why we do not recommend these servos to be used in helis. Helis generate a very high frequency vibration due to the high rpm of the engine and the close proximity of the engine to the servos. >>end quote

Use Futabas' s-148 servo, they cost about $15.00. I've sold over 12 Gas N' Go Nexus Helis', not a single servo failure with the s-148.

I have used s-148s on my nexus for 4 years now and havnt had a single problem until the other day when the tail rotor servo went bad--I flew the heck out of the nexus--the servos or the whole heli for that matter doesnt owe me a thing..joe
