Walkera v120d01 tail gear upgrade...?

Hi, new to the forum, first post... hope I'm doing it right.

I have a Walkera v120d01. It flies pretty well... but it keeps stripping the tail gear in very minor crashes and even during landings in grass that's long enough to stop the tail rotor...

Is there an upgraded tail gear set anyone knows of for the v120d01? (note: the tail gear is DIFFERENT from the v120d02).

I would love to spend more time flying this bird and less time fixing it...

Thanks!

I also like the V120D01 a lot. I fly it almost everyday.

The tail gear is the same of the V120D02, 4#6, 4G6, 4#6S and 4G6S, but different of the V120D02S.

Someone built and sold an slipper clutch, but I donīt know if it can be bought today. I donīt have it.

I see - thank you for the correction! You are right - I got a bunch of gear sets and they turned out to be the wrong shape/size. I remembered the "D02" part but missed the "S" - I just checked and indeed, my parts are for the D02S, that's why they didn't fit. The store I bought them from incorrectly advertised them as the right part for the D01 - so I ended up getting a refund.

But the good news then is that I can buy the D02 gears and they'll fit - thank you for pointing that out! I see plenty of places that sell D02 parts.

I upgraded some parts on my V120D01, e.g. new "autorotating" main gear (not that a fixed pitch heli can autorotate, but it's smoother - I'm happy with it) and installed metal landing skids on it because I kept breaking the flimsy plastic ones...

Hi,

send email to Bob in USA he makes slipper clutches. Ask him if the one he makes fits your heli. I think it might fit. You will never strip another gear after you install slipper clutch.

here is the address : slipperclutch@mi.rr.com

I still make the slipperclutch for the older ones. Just make darn sure when ordering that you make a BIG point that it's for the older one.
slipperclutch@mi.rr.com

They cost $15.00USD plus S&H of $5.55 in the USA and $8.55 outside.

I also have some of the older gear sets on hand that I stocked up on before making the slipperclutch.
