Newbie's quest: How to keep rotor moves freely?

[rkhoo]

Hi all, I got my BR from RadioShack in Canada yesteraday. It is alomst sold-out in every RS in my neigbourhood :)

My stock BR is a Version 2 with tailk-wires within the tail-boom. It hoovers nicely but tends to spin to the right while the trim on the TX is set to far-left. Any ideas?

Someone suggested to adjust the pitch of blades.

I do the free-bouncing test on the rotor assembly. The lowest pair of blades is not 'floating' freely, i.e. I bounced only once -- whereas other 3 pairs bounced about 3 times.

I have read a few threads about keeping your rotor moves freely is essential to the stability to this BR. However, I did not find any instructions on how to do it. Any pointers?

May I use some Olive-oil to free up the rotor assembly?

Or should I take it back to the store and try to see if another one is better?

Regards.

These things are soo sensitive and definately not for kids, only big kids. Needs much tuning to get it right and perhaps they should revise the model for less need of this. Cheers.

rkhoo,
The "free floating" hub is for hover stability. If hover is ok, then there is no need to mess with it.

For correcting yaw, which can't be fixed with trim, you have to change the loading of one of your rotor. By loading, I mean how much work it is doing. Higher loading simply means higher pitch. Make sure you change the pitch in all 4 blades and only a little at a time. Just twist the blade, hold for a second and release it.

The heli body moves opposite the way the rotor spins. For example, the top rotor spins CC or left. Your heli is spinning to the right. So unloading the top rotor will keep to body from going right. In other words, lower the pitch on the top rotor.
