700 CNC Clutch Block

IMHO I think I'd wait and just fit the Mod 1 gear kit when it arrives. Think the gears stripping are a lot more to do with the gears being to fine for the power than the blocks moving under load. I'm sure they do give more than the new Ally ones but the gear is the wrong pitch for such a high power heli

not that i have seen on any forum.

cheers

Arnt people therefore jumping the gun a bit here? Maybe this actually is enough to sort the problem. When the mod gear becomes available i will fit this regardless but i just dont see what the fuss is if nobodys actually stripped one with the new block fitted.

lee, my reasoning is simple. i know people that have moved the mesh and still stripped gears so your right, it may well be THE fix, time will tell.

in the mean time there is no way on earth a 90 shouldn't be mod 1 so i'm changing regardless for my own peace of mind. yet another stupid decision by align/jk.

cheers

update, lee i had a look and some info. someone has stripped the microheli gear using the metal block. so i stand corrected.



i have said this many times and i say it again, imo the problem is the lack of a 3rd bearing block. the mod 1 gears should hide that is my thinking. it will still flex, we can't stop that, but the teeth being larger should be able to cope. i have asked miro to make a 3rd block conversion kit, i'm waiting on an update. the problem is it won't be a simple bolt on job. we will have to drill the frames.

cheers

Heres a question for you - I watched some footage of Lucas Rivas' victory flight at the 3DM. The boy absolutely punished that 700 and probably does day in day out. How come the likes of Lucas and co dont seem to have this problem when a complete noddy like me can strip the gears doing lame tic tocs??!! Are the 'factory' pilots getting factory parts/prototype designs or what?

More than likely is the simple answer. They will always get the modded stuff first

Yeh im with ya with the 3rd bearing block... what a job thats gonna be getting the holes in just the right place.

aye lee, i'm not looking forward to it tbh but i'm going to do it. it will align (no pun) itself anyway so even if need to file the holes a little it'll be worth it. i'm going to order the parts and convert mine to have 3rd blocks, sod it. should be a simple mod in theory, lol.

cheers

It would be a cracking upgrade regardless like, go for it... might do mine now lol... you got me thinking. Document it mate if ya do it so we can all see
It kinda pees ya off when ya think it should have been like that from the start really.

Duncan Osbourn lost out at 3D Championship 2008 due to his main gear stripping!

Very unfortunate!
Just thought I'd mention it

Having read through this thread whilst contemplating whether to go for a 700 or not, it seems IMHO that someone might be able to produce a simple jig for drilling the frames for the 3rd bearing mounting holes and slots for the alignment lugs. Perhaps using a spare main shaft to centre the jig and the side frames to hold the jig.

Anyone contemplating drilling or machining the CF frames should bear in mind that CF dust is seriously hazardous to your health and take the necessary precautions.

no chance on my 700 lining up with the jig for drilling out some holes for a third bearing block
the original holes for the mainshaft bearing blocks are out of alignment
i hope any jig will be able to sort it out

in reply to the post about filing the clutch bearing block
only file a small amount off the lug off at the mainshaft side of the clutch bearing block so the mesh can be tightened up if needed

Sounds like that needs to be returned to the LHS?
