Hello,
I am sorta new to the micro heli thing. I bought a Skylark about a year ago, and after numerous mods and fixes.. I still couldn't get the darn thing to fly like some of my bigger gas machines did. I could fly it around the room and flly short distances but NEVER could get it to fly in forward flight for any distance. I would enter forward flight only to have it pitch up and come back like a boomerang!! has anyone solved this problem? or have a suggestion. I am working on a "cure" but I am curious if I am headed in the right direction.[8D] I know that just about anything can be fixed... IF you throw enough money and time at it, but in this case I am about outta time..and one other thing, This site has been the BEST help!

You are describing a common problem with low head speed helicopters.
Two common fixes to this are head stiffeners and higher head speed.
The advantage of Head Stiffeners, which reduce coning, is often argued. I have used this myself, and I think that it did help some.
Higher head speed is clearly effective in reducing the pitch up/forward flight problem. I have experimented with this and it makes a big difference.
So, consider cutting down your blades and putting on a bigger pinion.

Vince,
thanks for the post!. I believe that a higher rotor speed is indeed the way to go. I think I took it one step further with a shorter custom made set of blades. WOW! what a HUGE difference! this might actually be getting FUN again!
