I am about to upgrade my Raptor 90 tail rotor to metal.

1. Would you recommend the K or Q brand?

2. I see that QUK lists two part numbers, RT-11 and R6T-11. I always thought that the 50 and 90 had the same tail rotor. What’s the difference between the two? The US stored only the RT-11 part number.

I have Both, and my Q's developed both Lateral and AXIAL play quite quickly.

My K's are absolutely slop free, and look much nicer

Same as Colsy, The Q's were sloppy after only a few weekends flying, although I was told that they "take up" the slop when loaded.
The K's on the other hand have been fitted since they were released and are still absolutely slop free.

Thanks for the input – I almost ordered the wrong one.

What’s happened to QUK lately? They are suddenly behind the power curve with technology and quality. They use to be NO 1 but it looks like those days are definitely over.

The reason there are two part numbers is the 50 sized was the first out and originally didnt come with thrust bearings. The 60-90 came out with thrust bearings and consequently so did the 50 because they are the same. It is just a date time issue.

If the K's do not have any lateral slop they are the only ones in existence, all other heli brands develop mild play while at rest on the thrust bearings.. The bearings get "loaded" during rotation. All others I have felt are the same way.

To each their own as they say. Good luck and have a fine day.

Rick, i agree but that is the way they are 'Honest'.

Also the the inherent play that exists in the pitch control arm's and bush assembly on the stock tail, is evident on the QUK Assy, whereas the bushes' supplied with the 'K' unit are sized to suit and exhibit no play between the pitch slider and grips, 'whatsoever'

I am a great fan in QUK upgrades and service, no doubt.

But on this occasion the Kasama assembly is better engineered.
