Not really dmr but I NEED HELP. Okay I have a vfc gearbox okay I just got a brand new motor the Matrix high torque long type. It pulls the spring all the way back. But as the TM eg1000 did it gets locked and stuck in the back. I can still pull the trigger but it will go back and go back to same stop and not move. Basicaly the gun won`t cycle need help please and fast.

Are there any bearings or anything on the spring guide or piston that may stop it from going any further?

 

[nelsonho396]

Spring guide has bearings. BUt it just freakin weird. I have a feeling I should shave part of the last teeth on the piston down a little. Okay piston head has bearings and spring guide has ball bearings too.

 

[akfortyseven]

Why don't you try to take one set of bearings out then try it?

 

[nelsonho396]

I will try anything else I should try?

 

[akfortyseven]

A higher voltage battery?

 

[nelsonho396]

Anyone have any idea ?

 

[nelsonho396]

Anyone other idea I have a lipo 11.1 already

Sounds to me that the teeth on sector gear and piston doesn't like eachother, A.K.A there is too many teeth on the sector gear compared to piston.
Try putting piston and gears in and then start turning the bevel gear, if the gears stuck in the end instead turning the teethless half, you got a problem there.

 

[nelsonho396]

What should I do then cut a teeth off or switch the sector to a cyma gear

 

[akfortyseven]

Try counting the teeth first, the piston and sector gear should have the same amount of teeth.

 

[nelsonho396]

Okay besides that anythign else

I think WorstInFinland probably diagnosed the cause.

The only other issue I can think of is bad shimming. However, I don't think this as very likely.

What size spring you put in it,and what ratio gears are in there?
