Just wondering what all you guys are running as far as maximum pitch and cyclic, and where you have your needle on the OS50.

Local pro said i had to much pitch cause it was boging the engine to much running 10 to 11 degrees pitch, and 7 degrees cyclic. Engine has been running good and is probably a tad to rich.

those numbers would well make a rich engine
bog.

You really dont need 7 on cyclic.

It's all about control and finesse, not slamming
full collective and cyclic.

Ask people like JK or TB and you'll find that
they dont run excessive headspeed or huge
pitch. They know how to manage power.

Yeah, one of the first things he said was he didn't have to move the sticks much to get it to do what he wanted. the second thing he mentioned was his Craptor 50 was for sale. and that was WITH the brass weights in the paddles.

he sugested lowering the cyclics to 5 and pitch to 9 or 10

I think you'll find that 5.5-6 cyclic and 10 is
more than enough. And remove the brass
paddle weight.

I think my Evo is mechanically set to +- 11 or 11.5
but I never use that and limit the ATVs to +-10

Yeah, i had removed the brass weights for him, and found out myself it was still stable, just quicker, it's still in the high stability mode, any reason to change that? We also tried some TT600's that worked much better then the mavrick blades.

I'm running about 10 and a 1/2 positive and negative pitch with about 6 degrees of cyclic. On the OS50 with a standard carb, I was running a bit rich on the low end from factory settings with the main needle a little more than 1 turn out on Magnum 30%. (Thanks to Todd Dudek and Alex Rodriguez for the help there.) Anything will bog if you are too aggressive with the cyclic and collective..........even a 90. As Z mentioned, the key is to keep those controls smooth and practice as much as you can. You'll find you don't have to be super aggressive to do many of the 3D moves out there.

As for the weights in the paddles and the head settings, that's all personal preference. Do yourself a favor and try them all over an extended period of time. You'll eventually find what you like for your particular flying style and then you can stick with that setting no matter what anyone else runs. One thing I will say is try to fly a good number of flights after each change just so you don't write off a particular setting too quickly.

all you do is look at where the pitch of the blade is at then hit full elevator or aileron, subtact what it was before and wala.

Actually, you can check cyclic pitch by just measuring the pitch on the blades when they are 90 degrees to the input. For example, if you want fore and aft cyclic pitch, put the blades 90 degrees to the tail boom and move your cyclic stick while your collective is at 0. If you want to check left and right cyclic, place the main blades parallel to the boom and then move your right left cyclic while keeping collective at zero degrees.

Another way tho check is to move the collective to 0 and check it that way. Either way works fine, Chuck

I run +/-10, +/- 6 on the cyclic, brass weight removed. 60L carb, SAB-5RS Hatori, WC30%LV. I primarily set the high needle by looking at its performance during long climb outs.

I run +-11 degrees, not sure about cyclic but close to max travel on swash, with brass only - the Evo flies like a rocket, and it very responsive. autos great too with TG 600's...
