I am new to helis and got a Raptor 50v2... I've assembled it and setting up the radio!!

I have some problems though!!
When I rotate the blades manually I hear some noise between the main drive gear and the drive gear that is on top of the clutch!! Is this normal??

Also some of the servos when I don't move the sticks keep making a noise...

TR Belt Twist

DjBac

You Said:

One thing you might want to look at is the tail rotor drive belt. Read the instructions carefully. It is supposed to have only a 1/4 twist in the belt. It is "very easy" to get more that the required 1/4 twist in the belt. When it is installed correctly as the main rotor turns to the right looking at it from the top the tail rotor blade should rotate towards the rear of the helicopter.

To check remove the tail tube and look down the inside of the tail tube and make sure there are no twists in the belt and then rotate the belt 1/4 turn making sure that when the belt is rotated the main rotor head moves to the right and the tail rotor moves to the back.

The clicking noise made by the belt touching in the center of the boom (due to having excess twists in the belt) is transferred to the area of the gears making you think you have a gear problem.


Servo noise:

Remove the control link on the servo(s) that is making the noise and see if the noise stops. If it does you may be overdriving the servo, or may have links that are excessively tight and the ball links may need to be resized slightly. If the servo is over driving you will need to adjust you ATVs or adjust the position of the ball on the servo wheel.

Just some things you might want to check. Hope this is some help.

Well the noise from the gears appears even with the bolt off...
So it is not the belt!!!

About the servos, it should be a tight link beacuse when I take it off there is no noise, but in order to get NO noise I may have to twist the link more than 2 turns and this will turn out with more lenght!!

1. Remove the flat washer that came with the engine.
2. Your servos are chattering - due to poor quality servos, binding or not properly linked.

Do you have an OS motor?

Pay close attention to the flat washer that's on the end of the crankshaft. As Raffy said, you must remove this washer or the clutch bell will drag, making a grinding noise.

This happened to me, and the reason was I didn't realize the extra washer was there. You have to look closely. The fan should mount directly to the end of the crankshaft with no intrervening parts.

Servo jittering can be caused by binding linkages.
My suggestion is to make sure each and every linkage operates smootly, without binding, or slop. Take whatever time it needs to do this as perfectly as you can.

Also it's helpful to see/talk to other flyers, and the Rappy 50 is pretty popular, so almost any flying field these days has at least one of them.

I have a couple of Raptors, a 50 and a 30 so if there are more questions PM or email me.

You should also check out Raptortechnique.com

Regards,

Henry

Thanx eveyone for your answers... I don't remember if I have removed the washer (although I've read about this proble ).... But whatever I do I do it based on raptortechniques.com

I may meet Sotiris (SPB) this weekend to check my heli!!!

My servos are new... S9252, 9253(throttle), 9254(tail)...
So I suppose it is just the linkages...
But, for example the linkage for pitch...
If I shorten or lenghten it there is no difference because it moves smooth....

Digital servo's make a lot of racket even when they aren't doing anything in particular. Its normal.

Washer on start shaft

DjBac

I understand that there is a washer on the bottom of the start shaft between the "E Clip" and the bearing in the clutch hub on V2 machines. If this is left out the "E Clip" can drag on the bearing and cause some noise. Some people have left the washer out during assembly.

Just something you might want to look at.
