"Bouncing" during tic tocs
My evo 50 seems like it is bouncing when I do tail down tic tocs. I have no problem doing them when I do aileron tic tocs but elevator tic tocs are a hassal and is hard for me to keep them going. Im using a Revmax, 2000 head speed, no weights in the paddles. Does anyone know what is wrong. I can do them with the stratus on the sim but not on my evo. Can it be my collective managment?

dampners/engine tuning and collective management are all factors
my old evo did the same, on colder days it would be better

Cut down on the coffee before flying.

Or...

Try some EXPO on the fore/aft cyclic. I run 24%, however I run 620mm blades that weigh 165 grams. If your blades are lighter and more aggressive (i.e. Mavrikk, MAH, etc.) you may have to run a higher value in order to achieve the same results.

Hey Marc I hace the Infinavation dampeners in there. Should I take out a oring on each side to see if it gets better?Cliff

Mine does the same thing, with both the infination and the stock rubbers. I think it's the nature of the beast, and why you don't see many vids of Evo 50's doing TicTocs.

No, taking out an o-ring would make the dampening softer and make the problem worse.

guys,

soft/hard dampening, you'll see the same bouncing issues during tic-tocs....

It's always there a little, but it gets MUCH better with stiffer dampening. I don't notice it during tic-tocs. Mine bounces during 4 point flips, but it got much better with the Infinivation dampers.

Hey Marc what kind of paddles are you using, are you using the stock ones? Any weights in them, also are you using any expo?Cliff

I can do them with the stratus on the sim
Cliff,

The Sceadu is not going to tic-toc like the Stratus. The Stratus has a huge power to weight advantage. On top of that, a Stratus with a 91SZ can do +/- 13 degrees of pitch. With some collective management and getting everything you can get out of a 50 hyper, you can do +/- 11.5 on the Sceadu.

It'll help to get your Sceadu as light as you can get it. 7.5lbs shouldn't be too difficult. A 2 cell li-Ion pack with a Duralite reg. will weigh right around 4oz. which is about half the weight of a sub-C pack. Without the weight of a big battery up front, you'll have to lose the H-fin and switch to a CF V-fin.

I have the Infinivation dampers in a Sceadu and yes, it will bounce if I allow it to. You're gonna get the bounce with too quick or abrupt of an input on the fore-aft cyclic.

Keep at though... once you figure it out, tic-tocs are easy when you fly a bigger and more powerful heli.

Hope this helps,
andy-

Cliff, stock paddles with no brass weight. I leave the lead weight in otherwise it gets pitchy in FFF. I always run around 30% to 40% expo on cyclic on all my helis. I don't think more or less expo though would have any effect on the situation you're describing.

Guys,

Try negative delta, increase the flybar tilt range, reduce the flybar input, and tighten up the damper (infinivation, R50 red dampers etc).

Or... wait till CSM comin out with CycLock.... throw away those flybar contraption, mechanically reduce the main blades input from swash to 1/3.... you are ready to go....

A local 3D heli flier also commented on the "bouncing" during tic tocs on the Sceadu Evo. He tried everything including the full metal blue Hirobo head as well as carbon extreme dampners. Finally gave up trying to stop the bouncing or wobbling as he calls it. He said it's just the nature of the beast.

Why buy?? when you can borrow and no return

thanks for all the help guys. I fixed the problem.First I added about 15% expo, but it didnt help that much, then I added the gold weights in the paddles. When I was having the bouncing problems I had no weights in them. After I put them in a finished the rest of the flight that was a huge improvement. There was absolutly no bouncing and it felt like it was the sim. Now she is flying perfectly and I am happy!!!Cliff
