Very difficult to find that.

IMHO, there is another way to increase torque on tail.

If you can't find this gadget, try to increase weight on tail blades, running bigger tail baldes for example.

It was used on the Falcon 800 series helis. Unfortunately neither the manual nor exploded view have an actual part number, just an assembly number. I have one (sorry, not for sale) and it has no markings on it at all.

Ok... This is a matter for "trail and error".

You need to check that bigger tail blades don't be hit by main blades.

You know that your heli needs more power on tail.

Power is momentum times rpm.

P = I x RPM

You are looking for a solution to increase rpm... Ok?

But, If you can't find the gadget to do so, then try to Increase the momentum...

How?

If you have 85mm tail blades, try with 95 mm and more, taking into consideration that main blades don't hit the tail blades.

Paint it... Put some sort of tape on each blade to gain weight.

How much?
Well, if you need to increase RPM by 10% for example, that is the same amount you need to increase total weight on tail blades, that is 5% on each blade of course.

You will see the differences.
