Hi,

I want to increase my head speed from 1800 to 2000-2100 but i am still using my stock plast blade grips on my Raptor 50.

Some guys at the field say they are strong enough and even just as strong as metal while others say no way.

What is the real truth? DO i really have to dish out $100 on metal blade grips?

ive been running plastic blade grips for 3 years. no problems and im sure everyone else will agree. the only part you dont wanna run at high head speeds are wood blades and plastic heads. go for it!!!

I ran 2150 HS with plastic grips with no damage that wasn't self inflicted.

Grips will be fine.

Make sure the radial bearings fit snugly, if you get any slop between the bearing and the grip replace the grips or you will get woof and poof.

From time to time, perform a complete disassemble for the whole tail slider and check everything....

For high speed, Plastic grips not a problem but... original tail bearings could be!!!

New axial bearing you need... the ones with black a red sides...

The OP was asking about Main rotor Grips. It's up to you but I would upgrade the tail hub to the PV0499 SUS hub. and use heat shrink tube to retain the pulley pin.

I agree! Upgrade to the SUS tail hub, it's not pretty when that thing flies apart... It happened to me when I first got my Titan after about 10 flights.

Thank us later.

Use a Trex 700 tail rotor hub & grips - $22 complete for the V2 version - and make sure you get the V2.
The Trex TR hub & grips have thrust bearings vs. the Raptor which uses 2 radial bearings and no thrust bearings.

The Raptor 50 uses the same diameter TR drive shaft as the bigger Trexs (and the same size as the TT R-60 & R-90).
The geometry of the Trex hub & grips is close enough that it is plug & play.

The only difference is the Trex has one grub screw to hold it to the drive shaft where the Raptor has 2.

I use this on my R-90 instead of the original TT R-90 TR hub / grips.

Oops... sorry...

Well, my opinion with metal main grips...

Look pretty nice but on heavy crashes you need to replace the whole thing...

Plastic grips are better... when you crashed , you only need to replace the bolt and ball...
