Flying mine with Edge 623 blades (swapped out 606's as its 10 1/4 pounds and can use the extra disk).

I noticed the other day if I go straight up and aileron roll to the right to make a sideways loop if I increase the collective a bit too much the tail makes this whiny sound and blows out...

I have rail tail blades on it, does it mean I need 105mm tails and not the 96's, or does it mean the belt is loose? I tried to hold the tail and turn the rotor as much as is reasonable and I don't detect any sloppyness or loose belt jumping teech or whatnot.

Can you guys try this maneuver if you haven't seen it yet and tell me what happens if it holds or not? Again I can to it easy like I do my gasser, but when I get aggressive with the collective like you want to throw it hard to the right the tail is losing it.

Head speeds are 2000, 2150 and 2300 programmed.

Thanks,

You are running 2300 when the tail blows out?

I run Rail 106 tails on my E6 because I found the 96 tails lacking authority in certain situations. Or maybe it was just my lack of collective management.

Ah
I want to say I'm running 2150. I usually don't use the 2300 for long unless I'm barrling down the field at full fff speed.

I think I did try it at 2300 and still blew out, not 100% sure on that. I did try 95mm radix didn't help, I think rails are fatter anyways should be better. I have a set of 105mm tails, I could try that down the road and see what happens.

Thanks,

One important thing to remember is you must have a 4mm gap closest to the tail transmission.

Here: http://synergyrchelicopters.com/for...php?topic=218.0

If the gyro is stalling the blades with full throws the tail can blow out as you describe.

Thanks,
Chris

Raja,
What Chris describes is almost certainly whats happening. I have my right stop set at 6mm.

OH!
I maxed it out with helicommand after replacing the cgy750 out. Betcha thats my issue I hear the tail get noisy when I fly sideways to the left, waaaaaahh like that. I'll dial it down this evening and recharge the packs for tomorrow to try out.

Thanks guys!!

OK
Danny I just programmed the throw in HC3SX to be less, now its 60 to the right and 110 to the left. Used to be 110/110. Is this OK?

With 60 I get a 4mm gap between the pitch slider and the bearing end on the tail shaft. The other end, left rudder, practically goes to just about the end with 110 throw and looks to be about the same amount of pitch in the blades compared to right rudder.

Thanks guys,

Well
Limiting it to 4mm from the end didn't help the tail to not blow out.

Need larger tail blades or some other issue?

What servo, head speed and tail blades are you running when this happens?

Thanks,

How many degrees of pitch top and bottom? When does the tail blow out, what maneuver are you doing?

These question just help narrow things down.

Thanks,
Chris

I think about 13 to 14 degrees or so. I'm not at full collective when this happens, could be at about 10 or so.

I'm climbing out tail towards me and then I aileron right to make a sideways loop so to speak. As I attempt this the tail sounds like it whines and it does some sort of the beginnings of a piro flip.

Now if I'm not climbing out aggressive I can aileron over to the right and do sideways loops no problem. It just gets aggrevated when I try to do it while climbing, but not at full power. Call it 80-85% stick my best guess where hover would have been around 65%.

This is the only place I see the tail blow out. Otherwise I can fly no problem.

I would suggest bumping up the headspeed to 2300 when really pushing the tail, especially with 96mm blades. Otherwise, try out the 105mm blades.

Also, have you tried this move running the Rail 606's?

Yes
Did try it at the 2300 speed still happens. Did not try to downgrade the mains to rail 606's I have 623's on there now and didn't notice this problem before with the 606's though I may have not pushed it hard enough.

Anyone else try this to see what happens with theirs?

I'll try it this weekend but I'm running 106 tails at 2300 so I'd be shocked to see it blow out.

Oh yeah 106 rails will probably work
If you have 96 rails or 95 radix, try those if you want, I tried both and they both blow out. Are you running 700's on the head? Mine is only 623's its an E6 not an E7.

Oh OK.
You know I didn't notice the issue with the 606 rails, maybe the 623's caused more torque and they need more tail blades.

I could take the tail blades off my Spectra or 1005 at the field and try them on the synergy and see what happens, they are SAB 105's.

Is it possible you didn't have the issue with the CGY750 but now you do with the BeastX? I'm flying with mine with the V-bar, rail 606 main and Rail 96 tails and I never had this problem myself. BTW I run 2200 head speed.

Possibly
I never noticed it with the CGY750, I do have Helicommand HC3SX now.
