just got this electric 500 almost dialed in the air and feels a bit squirrely, "maybe Im just used to bigger models that are more stable. rates are down to around 45 cyclic but still feels touchy. anyone here using a flybar weights on smaller models?

+1 on adding expo. It will soften up the controls alot.

Ha, have that on my other birds and didn't even think about it so weights on smaller models dont have much affect or what??

Also try lowering your head speed a bit to slow down cyclic response.

I fly a 450, so not sure on a 500. However flying with no weights makes it feel squirrely and in breezy conditions has a lot of affect. With flybar weights calms it down and resists wind a little. I don't put fly bar weights out or middle but all the wayagainst flybar cage. I fly with no expo also as a prpreference.

fwiw..

WC has it right...Exop and lowering cyclic throw should calm it down...You could use dual rates, cut the cyclic to 70% and test hover....It is a feel thing, tune to suit...

Good luck!

+1 to Expo and dual rates.

Weights will definitely help with hovering stability.

Also check for tight links and bearings in the head and make sure the flybar sways freely.

The issue with a feeling of squirreliness compared to a larger heli may be reduced by lowering headspeed a bit. Many like to crank up the headspeed on 500 class helis to make it skit around like a large 450. This will lead to an overly quick or squirrely 500 helicopter.

Also if you can get hold of some of the original plastic paddles instead of the carbon ones (if thats what you have?), will make it a bit more stable.

It may not be your prefered solution but upgrading to FBL makes a big difference on a small heli, much more than on a larger heli. My 450 became a much "bigger", more stable, more powerful and better heli once converted to FBL.

Flybars

and the weights dont do much

The speed of response of the flybar to commands can be adjusted as follows:

**Increasing the weight of the paddles slows it down
Increasing the area of the paddles speeds it up
Increasing the rotor RPM speeds it up
Increasing the aspect ratio (span/chord) of the paddles speeds it up.
Increasing the length of the flybar speeds it up.

**This is the same as using weights and the "mechanical" equivalence of using "electronic" exponential. Furthermore its adjustable by sliding in or out on the bar without having to change paddles.

For those with FBL units, now you can imagine the "electronic" equivalences of your settings...sort of speaking.

This is 100% correct

Ah I miss good simply flybar tweaking! Paddle Sim?! Please, give me a break!
