My maxi joker 2 cameraship as we all know some some what of a less robust tail. i want to make it hold better, but am not ready go put a separate motor for the tail. Does anyone know of any tail blades to increase my tail stability? Links please.

Also Should i be looking for longer to wider blades?

Also I am running 2 6 cells on the joker with the big blue motor and the proper pinion.

Thanks.

130mm SAB (I'm assuimg yours are SAB) tail blades spinning at 5800 rpm should be able to handle an 18-20lb ship swinging 800's at 1000 rpm. If you don't have enough tail authority with 130's you need to spin them faster. You can't go larger than 130mm unless you make your own.

4mm? I'd guess that would make a difference. try 'em out and see. Certainly won't hurt.

Cool, but whatever you do, dont put on to long tailblades, otherwise youll risk a collision with the mains in a rough landing, but that also depends on how long your mains are

BTW, in what way did it helped the tail? reduced gain on the gyro for heading hold?
