My R50V2 is not able to roll very well. I have increased my throws on the cyclic....... but it's not any better. I put my KSJ paddles in the back hole and it's still a dog!!!!!

What hole do you guys have the ball screwed to on the washout arms. The inside hole closest to the mains shaft or the outside hole???

The outside hole is used to increase the roll rate, but the problem is the helicopter has a more twitchy feel to it. The best way to increase the roll rate is to run a higher rotor speed (Not to exceed 2000 rpm) or to run different flybar paddles.---from http://www.raptortechnique.com

Also, make sure that you have enough swashplate throw (tilt).

Adjust the fore/aft and left/right cyclic servos to achieve 16 degrees of swashplate tilt at full servo throw in each direction. An easy way to accomplish this is to measure 10mm of travel each way from one outer (static) swashplate ball, from center to center. Keep in mind that if you move the stick to one corner (i.e. full forward and full right) you will have MORE than 16 degrees of swashplate tilt, which can lead to linkage binding and possibly a crash. To eliminate this possibility, I use a cyclic limiter ring. This device restricts cyclic stick movement to allow the same degree of swashplate tilt, in any stick direction. Set the main blade pitch to range from -4 degrees at low stick, to +10 degrees at high stick for hovering modes, and -10 to +10 degrees of pitch in 3D modes. Also, I replace the stock wooden blades with Funkey or Airborne Models 600mm fiberglass blades and swap out the stock flybar paddles for KSJ paddles, mounted in the rearward hole.

timely post! I was looking into improving the roll on the 50v2 too.

I will move the ball out to the outside hole on the washout arms and see how "twitchy" it becomes. I'll be running the stock paddles too. My cyclic servo arms have the balls located about 10.5mm out (6 star futaba horn, middle hole location). I run about 1600 rpm in normal and 1800 or so in idle1.

I will post my experiences after trying it out this Saturday. Anyone who has actually done this (ball on outer hole) want to comment on their experiences?

Funny?

I have the raptor 50 v2 in stock form with links on the inner washout hole and it rolls pretty quickly. Haven't tried the outer hole yet. You got enough throw on your swash? P.S I'm using the raptor carbon fibre blades.

All of my Raptors are set up this way. If you want quicker cyclic response for 3D, this is one of the things that you need to do.

moved to outer hole leaving everything as before (stock paddles, woodies, same servo horn ball position, same atv and expo etc).

The roll rate was improved. More responsive. I would guess ~40% improvement if you had to put a number to it.

I did not notice a glaring difference in forward flight, turns, figure 8's, or hovering. I was still on -15% expo on the cyclic. I would not classify the heli as being extra "twitchy".

The major difference I noticed was that my stationary rolls to the left (tail in hover) were a lot harder/uglier than rolling to the right. Could be my lack of experience (I roll more to right than left normally) coupled with the increased response (outer hole). I just know left rolls weren't that ugly before the change. They often ended up more like corkscrew rolls. Must be putting in un-intentional fore/aft cyclic while pushing the control stick left cyclic.

Plan to keep this setup for the time being to get used to the flying characteristics. May look into increasing the servo throws (moving ball out on the ailer servo) for increased response in the future.

Any helicopter with a clockwise rotating main rotor will roll quicker to the right due to torque. Rolls to the left are against torque and therefore take more control input to achieve the same roll rate.

Timing is a big issue. If your timing is off you won't roll any faster no matter what configuration you use.

I have been running the outer hole since I built my two years ago. I run the 20g white MA paddles, long flybar and 1900 head speed. Mine is real snappy. I'm actually in the process of toning it down a bit and slowing down my flight speed so I can fly smoother and closer in. Less banging and more caressing.

Use the caliber 30 flybar (it`s 3/4 of an inch longer)and caliber paddles with no weights , you`ll love it. I do.
