I don’t believe your deduction as to the cause of the high speed piro is correct.

Charles i've been flying for 4 years and have many tail failures of one sort or another, mainly carbon servo rods dropping off! I know when my tail has let go and the fact that the heli piro'd to the left is even more conclusive don't you think.
Personally if i were you i would keep your comments to yourself, i thought we were all beginning to get along here but i was wrong.

Also now that it has been said on another thread and mentioned here that Todd Bennett has said that the manual IS incorrect and will be changed it leads me to think that maybe i should have gone to a solicitor instead of here.

You guys have personal contact with JK and TB and suggest what you discuss at the field you keep there to save their embarrassment in the commercial area, this kit has not been a good experience for me and I'm beginning to wish i had never seen the damn thing, yes it flies nice but thanks to hours of my own input, the kit in itself is inferior and now substandard, when it is back together the airframe is up for sale and i'll plough my money back to thunder tiger after all i can go to my LHS and pick parts off the shelf.

SYNERGY R/C if you are watching, my torque tube slipped, my heli crashed because of it and i am seething this is the last straw as far as i'm concerned. I've tried contacting you via mail but keep getting returns, it seems i am spam blacklisted since my posts here, after you sent my serial no.

i dont think it matters much if they are flipped or not just need to make sure they are tight...ive seen charles beat on his synergy and his are not flipped and all is fine

if they are not tight you will lose tail simple as that...

Im agreeing with Droid.

After all the hype I was looking forward to this model. After all the issues it gets to the point where i dont even want to fly it.

so lets list all the issues we have found

1) collets are wrong ID
2) threaded holes are either stripped or tapped to wrong dia.
3) Plastic parts are close to useless. I had a fan with 3 fins malformed. Fan shroud which was warped
4)tail pins shear and fall out
5)Clutch doesnt engage unless fan hub modified.
6)Swash guide is too flimsy and the swash pops out of it.
7) swash guide can foul the mixing arms at times
8) ball links are wrong size.
9) the link lengths in the manual are completely wrong.
10) possible sprag outer slipping.
11) Torque tube ends fail or spin in the tube.
12) tail grips are variable size at best.
13) my fan hub i could run my car engine off it wasnt even round.
14) start shaft isnt hardened so you cant remove it form the model when you need to redial the fan (which is almost every second day)
15) i got screws in bags that werent even the right screws....examin the exhaust side muffler bolts..one good one, one bad one.

With all due respect to JK and todd, what the heck is next?

How many models have been downed due to these failures?

I think we were all humped royally.

Synergys lack of any response, even on their forum to these issues has been disappointing.

No, for a clock wise rotating rotor head the heli will always prio left if the tail rotor stops for what ever reason. That was not my point. Yes the set screws were tight in the collars and you can see that in the pics you first posted, so why are you saying the TT coupler failed?

I'm sorry you crashed Droid but until I see more evidence of the TT coupler failure I'm sticking with my current position.

I thought RR was here for everyone to post their comments, helpful to the RC Helicopter community?

I'll say it again. A more solid joint is needed for a TT application. The easiest way to do this is to drill and pin/bolt.

Friction joint bad, solid joint good.

Is that clear now??

And before any wise guy says that could have happenend when it crashed it went in nose first vertical at idle and we all know there is no way the drive is engaged when the motor is below half revs , right!!

Synergy RC has acknowledged and is working on some of your items. For the other manufacture related items they want you to contact them directly so they can send you replacement parts.

Synergy RC has responded here and on their site but cannot be expected to respond to every post. I even have problems with the forum format where I have posted building suggestions but after a few days it’s off the main page. It’s not very efficient to answer the same question over and over.

If the main blades were spinning the autorotation gear will be driving the tail rotor. That is how we are able to do pirouetting autos.

SHOW ME EVIDENCE AND A PICTURE

Feel the love!!! .I have been doing wild piro's and I took the tail apart after reading all this and I have found the tail to be ok.I have only ten flights but all seems ok so far,

Charles are you lacking something upstairs?? Yes, the pinion driving the torque tube was driving, the hex insert into the torque tube was driving, but because it had spun inside the torque tube it was unable to transmit the torque because it was LOOSE AND SLIPPING!!!
Is that plain and simple enough for you to comprehend???

T/r drive

There is a picture that clearly shows the t/r drive end piece to have it's splines worn down. I don't see any reason to doubt that it spun in the drive tube. Whether the set screws were adequately tightened would be impossible to determine over the internet. What is possible to know is that there are several individuals who have commented in this thread that they have had similar problems with helis that are less than a month old. One can only presume that the builders had some experience, if they were buying a top end heli like the Synergy, and thought they were adequately tightening the screws. If it were my heli, I'd drill a hole through the whole works and cross pin it with a 2mm screw similar to the Raptor 90 SS drive tube. steve.

umm steve

who else has experienced the tt slipping on the splined/collared end. you refer to others, but to my knowledge this is the only one which has apparently had this particular problem. there was some other mention about not lining up the flats properly, which is purely builder error.

as far as building experience goes, one never knows and cannot assume. after all, there were some people who bought the kit and then started screaming for bungs and ant tubes and loops for the ant tube to go through--the kind that come with every raptor and trex--not particularly top end.
