Now that I got someone's attention, it is not my Raptor that stinks, but my piss-poor set up.
All the pitch curves are pretty decent, but for some reason, I cant get it to rotate in roll or pitch axis fast enought. The roll rate is perfect for Class III or FAI rolls, but to slow for sideways flips. Same thing for fwd or backwards flips. About 2.7 seconds for a full 360 rotation.
CG with fuel is dead neutral (skids even w ground)
Head speed is 1900 to 2000 RPM. I am using K&S paddles with Mavrikk 600 carbon blades. (yes, and they are better than the stock TT carbon)
My hi rates are almost 20% higher than my low rates, yet it does not seem to make any difference in the rotation rate, but are very noticeable on hover where I dont need it.
The paddles are aligned well, and the heli is very smooth. I did sanded a bit the leading edge of the paddles to cut down the edginess in Fwd-flight. I am thinking about trying the MA paddles but I am not sure how much I will gain over the K&S.
HELP!!!!!!!!!!!!!! Please, I'm open to any suggestions.

Hi there,

What you describe is a little strange though...I'm running the stock paddles and get a better roll rate (maybe 2sec for 360 degrees?). Headspeed's not that high, (definitely below 2K). My guess is not enough aileron throw? How many degrees of cyclic are you getting?

I am using pretty much the stock setup per instructions. 10mm arms on the roll and 11mm on the elevator, I mean pitch. My ATV (Futaba) are at 100 on both cyclic. Ths DR are 80 low, and 96 on high.
This is new heli with just 2 gallons flown. No play anywere.
I guess I have to measure the throws on the cyclic to get a point of reference to go from. I am too tired right now since its 4AM here in OH, and dont think I can measure anything accurately right now. As soon as I measure it, I'll post the cyclic angles and you guys can tell me if they are close to being acceptable.
The KSJ paddles have 2 holes for the flybar. I am using the rear one. That is the correct one for quick reaction, right?
Something is definately wrong with this thang.

Your blade grips aren't by any chance forward facing (ie with the control arms facing the airflow)?

Models tend to become more stable with forward vs rearward facing grips

Blade grips are facing rear, just like the picture.

I use the Carbon extreme dampers and MA paddles on mine with the TT 600 carbon blades which are better than Maverik., and mine will flip and roll extremely fast . I am running about 1950 on head speed.
Something isn't right I am with buddy kitchen check the washout location for the oval links. I have seen this more than once with the links on the inner holes instead of the outer.

Is the head speed decaying while you try and roll and flip?

URETHRA! We have a winner. Buddykitchen, you nailed it. In fact the last 3 post are showing me the problem.
The flybar control hoops are mounted on the inside hole on the washout levers. ( by far not a dumb question)
I am also droping about from 100 to 150 RPM on the flips, and about 100 on the rolls. Is that too much. I've been working that issue slowly with the fear of overreving. After I move the hoops to the outside of the washout arms, I will put even more throttle into it because of the higher load is going to see.
I read the ongoing post on the new TT paddles, so for now, I'm gonna change 1 thing at a time; then try the MA, the Vpaddles, or the new TTs.
I feel like drilling the stock ones, and play with them until I get new ones.


Thanks a lot. Jason, Buddykitchen, and rcadd1ct.

PS and everyone else who helped on this thread.

Set up cyclic to throttle mixing.

This will help keep the head speed up when you flip and roll.

A governor , like stated previously, will eliminate the need for additional mixes.

Thanks guys. I know all these things that you mentioned like cyclic to throttle mixing and the use of the governor. For some reason, my brain does not want to remember anything
I use a throttle Jokey Pro on my XCell, and previously, was using cyclic to throttle mixing with good results.
I will definately do the mixing on the Raptor, now that you guys got my brain kick-started again. I am somewhat spoiled by the governor on the XCell, and like to get one for the R50 in the future.

Flew the R50 today a couple of tanks. Added the cyclic to throttle mixing and the flybar control hoops are mounted on the outside hole of the washout mixer. Still flying the KSJ paddles. A whole lot better cyclic performance, but still not as fast as it should be. Is got to be the blades.

I remember well when I changed blades on my XCell from H I Products FAI blades to the carbon SABs, it was night and day the change in cyclic responce.
I take it that the Mavrikks are'nt as fast as I hope. Good, but not good enough. Now, to decide what blades to get. Decisions, decisions..

Well this ia an old thread, but needs an ending.

A bad setup can make any heli fly like a POS. I has a friend try his own setup (a whole separate program)on my old R50 and it brought the rappy alive. The magic setup was nothing but the stock 3d setup from the manual with a faily aggresive V curve for iddle up (100-60-100).

DUH!

happy stick banging!
