Belt drive tail woes. Help please!

[warboysastro]

Me again, :)

Having some issues with the Blinktrading belt drive tail conversion on my Zoom 400

With the boom just held into position in the supplied blue riser, with the belt running through the boom, the bearings seem too short to reach the belt and provide any support/guidance. Also, the position the belt enters the boom seems a little high; being about 3mm above centre.

The belt drive toothed gear is fitted as low down as possible, and nestles right down onto the one-way bearing. Also, the one-way bearing sits flush with the white main gear. I also positioned the belt at the lower end of the gear so the belt is as low as it will go.

A 'secondary' problem is that when applying maxim travel of 'up' elevator, the elevator rocker assembly will rub on the belt. However, this might only be a problem when I progress to full-on 3D!!

I'm trying to think of solutions... I could raise the blue tail clamp riser block on shims... This would help the bearings to align, and for the belt to enter the boom tube more towards the middle, but would cause the elevator rocker assembly to be more likely foul the belt when applying 'up' elevator.

How about stacking 2 sets of bearings on top of eachother, or even a thin shim plus the extra bearing?

Any thoughts from anyone who has successfully kitted a belt drive kit before would be most welcome :D

Regards,
Rob.

I've had a fresh look at it... the limiting factor in all this is the height of the one way bearing. Everything is currently sat as low as it'll go.

Looks like it's sadly back to a shaft/gear driven tail.

So the Blinktrading belt didn't work on this occasion :mad:

have you emailed blink to see what they say?

edit:
The belt also looks high in the boom, as if as you say, the boom it too low and needs to be higher

But as soon as I raise the boom, this lets the belt relax a bit and it rubs the fore/aft cyclic seesaw.

Argh! Nothing is simple!

Yes I emailed Dave at Blink. He's probably fed up of all my emails by now ;)

I'll have another play and a think tomorrow.

Don't want to speak too soon, but I may have cracked it...

A shot of the thing in the hover will be next :)

Give me a couple of weeks. Parts on order!
