700 Stripped gear with CNC Bearing block

[chemicalbro]

Its the poor attention to quality into the build materials or in the 700 more likely the lack of the third bearing block that will give the competition that ability to get back some market share.

I think that is a BIG part of the problem... they are only interested in taking over the heli market and pushing the maximum number of units.
at the end of the day if it continues people will jump ship to the something else and align will end up on their arses. or when they bring out their next heli nobody will buy it thinking "I'll wait until it is a proven design" with nobody willing to take the 1st leap of faith they won't sell many units.

if a company (any company) gets a rep for bad quality control it doesn't take long for people to stop buying their product.


i don't know if this was a one off but on sunday one of my mates stripped the main gear on his 600 in flight..... and he wasn't kicking the arse out of it.
maybe align source their gear material from the same dutch cheese factory as their bolts

Just out of interest was this a new 600NSP without the 3rd bearing block? I hear the newer kits are now shipped without the lower bearing block.

[chemicalbro]

it was a new NSP (about 3 months old) don't know about the bearing block tho.... but i assume you're right

[barney]

Does the NSP not always been shipped with 3 main bearing blocks?.. It would be 2 x metal and 1 x plastic?

Don't blow a gasket,I I said you could, not would, I have no doubt your the best gear mesher in the UK but not everyone else is! My point was that a moulded gear will never,ever,ever,ever be as truly circular as a machine cut one. Therefore it IS possible for a lesser mortal to set the mesh at one point and it be slightly out somewhere else.

don't confuse blowing a gasket with giving my own views and findings after many months with 2 rex 700's and a lot of head scratching. if someone is not capable of meshing a gear then i suggest knitting or something.

cheers

If it is one without the 3rd block then I think we have the answer Mr. Holmes!!!

I'll find out at the weekend.

the mod 1 gears are being cut this week apparently barney, look forward to info on that front.

in mean time i'll need to stick with my own mods and see how i fair. matt has a serious amount of gallons through his 3 and i think he's hitting double figures with broken gears. it was 7 last time i asked him which was 2 months ago.

i do think the clutch block is a worthwhile upgrade as it's also a failure point. i'd say it's not the most common failure point but it is one. already been proven that it does contribute to this. i'll be 99% happy with a 3rd block and meshing and completely happy with mod 1 and mesh.

cheers

Thing is Align dont sit on there backsides! (Yes, Its open to debate whether they have cured it)

They actually addressed the problem by supplying a new modded main gear. They also did the same with the links. (I'm still using the originial links too).

Whether they re-call old stock I dont know, or how they deal with the importers with such things, but the part no with -1 at the end is a modified part. The new Main gear has an increased dia for a tighter mesh.

[raptorheli2]

align do fix problems thats true. coming from a synergy user to align has had issues but the synergy issues took months upon months to be resolved so i'm happy align is listening somewhat. it is a pity they can't sell an upgrade to fix this (bolt in 3rd block) as it involves some drilling of the frames. they could ofcourse make a mod 1 gear but i get the feeling they won't or they would have done so by now.

i also think we will need to live with moulded gears as CNC ones will be 4/5x the price and that doesn't seem to fit in with aligns business plans to me. with that said there is little point of them making CNC gears when the microheli one will strip anyway.

if i can be bothered i'll fit the 3rd blocks this week and report back my own findings once flown.

cheers

Lee the up down play is quite normal..but can be eliminated (not that I have done this either..LOL)

I'll nip over to the Freak and see where the thread is

Here you go.

MrMel...Check if your maingear can move up/down about 1mm (obs not tail gear),
If it can, Loctite residue from the factory has wedged between the upper bearing (inside the one-way unit) and the unit itself, so the upper bearing is not seated fully in.

Solution: Take it apart, clean, reapply new loctite & put together.

Any idea when the -1 maingear will be available Barney? I've been keeping an eye out for this to hit the UK but havnt seen one yet. Align apparantly called this the 'cold weather' gear!! I've read some US reports of the mesh being incredibly tight when first fitted but soon beds in and seems to last.

[barney]

Sorry no idea Pete, like you just following whats being said about it Stateside

[Stuart]

Time will tell I suspect if the larger gear is a fix - I have my suspicions that it will last longer but not the cure. Though 9mths later is better to have something than nothing provided Align are supplying FOC to customers.

my 700 with the 3rd bearing block has now had 4 gallons of fuel through it with no problems
due to the poor quality of the main gear not being round i did set the mesh tight, i set it at the slack point and made sure it wasn't to tight at the tight point
it did have a little gear wear to start with but it now has a constant mesh all away around the gear
and my std clutch bearing block had worn with the bearings moving around the housing if this helps with a bit more info for those of you not yet to have a gear go


and a club mate of mine stripped a micro heli gear with the ali clutch bearing mod but with out having an adjustable mesh and no 3rd bearing block and he's only flying circuits and eights runnig a ys motor

i don't beleave as sugested that its the more powerful newer 90 engines as mines got a gold head os91 c spec and still stripped gears

and i have not seen or herd of a 600 strip gears around my neck of the woods and i have just replaced my 600's main bearings and they were all totaly shot including the plastic housings, i've now got the align upper metal blocks and the quick uk lower block in it and no sign of gear damage
