Well awesome. So Align may have had this as an option all along? The description is horrible. As little detail as possible.

So this part along with the old style tail drive gear and we're back to 4.5. Hope there wasn't a real reason to change to mod .8 though on the auto gear?

So I bought some new 3G 600mm blades to replace my busted set.

I found the markings on the box very interesting.

2100 RPM max. Hmm. Houston we have a problem.

Those blades must not be "Pro".

Unreal.

We've seen align monitors this thread. Would really like someone from there to chime in on this potential gearing option. As it stands, it would solve the only gripe I have so far on an otherwise epic machine.

Good call Onthesnap, I put 105's on the tail, 700 rear landing gear, and governed my CC ESC to 2200 max, and the thing just performs beautifuly. My tail was rock solid today with everything I threw at it. Fast inverted backwards Hurricanes, tail down inverted funnels, rainbows, elev./ail. tic-tocs. Good catch. I loved it with the High recommended HS, but I feel alot safer with this setup, and the performance its great. Plus, I like the aggressive look of the kicked up tail

Nice! Did you try 95's at all?

My old 600e pro did a big backward inverted loop yesterday fast and something exploded on the tail we think the 105s touched the mains or one of the mains shredded airframe is a write off will see if I can post some pics later he was running 2300 rpm

I checked and there is no way the 105's can touch the 600 blades. Were the tail grips still attached to the spindle? Any sign of sheered bolts in the tail? The stock bolts are fairly soft metal. This is why I dropped in the KDE upgrade which includes hardened bolts. Now I'm running the QUK tail which is overkill. Also, if you over tighten the tail bolts they can give.

30 flights with 105's slapping the elevator full bore and no issues. Not even one tap of the tail blades to the mains.

What about with 623mm Edge blades and 105mm tails? I'm trying this tomorro and need to know if I'm an idiot or not...

Nooooo!!!! 623's don't fit even with 95mm tail. The Pro has a short boom for it's class.

[raptor50luvver]

All the bolts and balls were still in situ after the crash sorry just hasten to add he isn't blaming the airframe for one second we all know a million and one things can go wrong a link could have popped off etc.

All we know is there was a crack from the tail and a part of one main blade shredded off and the model piro'd down to the ground boomstriking and other bits coming off about 10 people were watching the flight as we were interested in the tail issue etc.

To add he is simply going to buy a new kit this week,shit happens sometimes in this hobby and yesterday was his turn it's all part of it really,he won't be the first person to write an airframe and deffo won't be the last.

Just posted it in case any more issues arise so it's been noted.

Edit just seen pics....105s tips are OK,wondering is main gear or auto hub blew out.
Was in throttle hold long before contact with ground,it was NOT a powered crash.

Yea I put them on and it was definitely a 'whoa this don't look right' moment. Just had to hear it from someone who knows what they're talkin about! Brand new 623mm FBL EDGE blades for sale! That's it, sorry to hijack the thread.. Carry on..

What the statement regarding the 2100RPM max. from Align?

Use at your own risk

How high off the ground was it when the failure occurred? I am surprised that the accident requires a re-kit; I have heard on and off of this forum that the new 600 frame is built like a little truck.

Sounds like a classic boom strike. Any broken links or balls backed out of the swash or grips?

I use red loctite on all swash balls and grips just for this reason. Never a good result when you loose a link.

Is anyone other than Raptor50luvver running 105's with the stock tail hardware?

We could do the math, but I would bet centrifugal forces at 2500 are higher than 2250 with 105's.

Anyway even if you run 95's I'd upgrade the bolts. There is just a long history of Align 550-700 throwing tail grips.

Im running this setup now. I posted a few posts back my setup. 105's, 700 rear landing gear, and 2200 HS governed on the CC ESC. Works perfectly, everything else is stock except for the CC Pro BEC. I ran the stock 95's and HS when I first got it, but after reading this topic, the lower HS sounded much safer to me.
I had to lower my gyro gain significantly to get rid of the fast rudder wag once I made the switch, but that was to be expected with the much bigger tail blades. Im very happy with this setup, I still have crazy fast climb outs and pitch pumps, nice hard fast stops, and heli still seems very fast thru anything I can throw at it. Still has nice nice loud blade farts too with this HS. I was concerned about the main and tail blades touching at first too, but no issues or boom strikes yesterday.

Wow! That was a hard crash. Sorry man.
