I just received the ys80 conversion, new plates, modified engine mount and pinion gear. Included was a couple of rectangular parts with holes, and a new o-ring. I assume the o-ring is a replacement not in addition? for the one between clutch and bell? So what about the squares? jigs or renforcements or ??? anyone know for sure?

Also on the extended mainshaft kit, the diagram looks as if the new bearing carrier is with the opening facing down, with nothing below it, which means the only thing holding the bearing in is the adhesive/press fit, is this correct? Thanks......

bad picture shows the parts:

sleep helped, but still unsure about other questions (mainshaft and o-ring). I don't have the original plates, but I think these 2 pieces are reenforcements for the clutch plate where the frame is cut out.
So which way does the squarish one go.....holes towards top or bottom, looks like it should work either way. I think they were glued on original ones, do u have original to look at.....what do u think?

more bad pictures (boy do i need a new camera-this one was free though):

YS 80 Conversion

av8er,

The two small plates go in between the cluth bell and the new clutch plates. These should already be on your helicopter but may have been adhered to the original clutch plates when you got your kit. The rectangular plate goes down low next to the 0182 bearing bearing block, the square plate goes up top next to the start shaft bearing block to holes should be on top. The o-ring is a replacement for the one already between your clutch and clutch bell. You are right the third bearing block does mount "upside down" however the bearing is glued in and pressed in as well. I am a Miniature Aircraft pilot and have been flying the extended main shaft for some time now with no problems.

Hope this helps,

Darrell

to those interested.......miniature said don't bother gluing.

appears the new o-ring is a little smaller btw, making the clutch seat inside the bell fully.

If you decide to glue to keep things in one piece, get the alignment right the first time. CA bonds the G10 VERY well. I goofed the first try and ended up having to soak the pieces in acetone to break up the bond.

That lower most bearing will have little desire to come out, both because of the loctite and press fit and because the only loads being applied to it are radial (nothing to help press it out the bottom).

Thx, yes i did use a drop of CA on each to hold them in place and instant bond like u said...luckily I had put them on screws to align....almost done.....grabbing a bite... .muffler and throttle linkage left...then to test flight, running 700's with standard boom and ys80.
