Hi all,

I have a raptor 50 and i have a lot of play in the rear tail grips (where they bolt around the bearings) the grips are as tight as they can go but not sure what to do now to reduce the play......

anyone had this on their raptor??

Cheers

I didn't know if i should put it layer of thin tape on the inside of the grips to try and pad them out a bit?

You could sand each side down a bit on the inside of the blade grip so when you bolt it together it will be tighter on the bearings? You could also wrap a piece of tape around the bearing to make them fit tighter. It really doesn't matter if they are a bit loose because when they are spinning around the centrifugal force will straighten the blades out.

Take Care,
Cheers, Patrick

There is always movement in the grips. It's just a crap design.

i sandid mine down just like raptor teq. said and it works great no more slop i also sized the ball link and glued the screw to the coller whare the bearings run through on the piviot. drilled out just a little of the plastic guidesfor the tail lincage rod. made the 3 guides realy straight and have no play and no restince. works realy good. i was using a gy 240 with the gain down to 60 and it holds rock solid..

I used a small thin washer between the bearing and nut. Plays gone and I too was able to lower the gain.

All my v1 & v2 tails have suffered from this to different extents.

they get worse with any ground strike, Ive lost a couple of tails due to long grub screw failing after ground strike.
So if it has a ground strike, replace the long grub scew(same at rear canopy mount and paddle locking.

Fix is very easy.
Pull the two nylocs that hold all on the long grub screws, thread them on a 3 mm longish bolt backwards with bolt just short of proud.
Hold the nut against the grinder trying to maintain a square as possible end, allowing it to rotate while grinding may help keep all symmetrical.

This then allows the nuts to nip up against the bearings due to removal of mating face radius rather than the bearing mount and letting the bearings float a little.

I also run a hint of loctite bearing mount to compensate for the excess clearance on the bearing mount.

ok to date.

Regards Don

Yep i had the exact same problem,,, like some one else said crap design, what i did was i read on Ricks R/C Heli that he used the JR Vigor Tail on the R60, so knowing that the R60 tail is almost identical to the R50 i went and ordered it, and i have to say it is so smooth and beats the hell out of the Raptor Tail

Here is the like to the page were Ron Lund describes what he did and the part numbers for the Vigor tail.

Okay previous from my last post about the Jr Vigor Tail Grips, i did a little experiment and basical i took the Jr Vigor tail case along with all the other parts for the JR Vigor belt drive and adapted it to fit the R50. So basically i have a Jr Vigor Tail case and tail on the R50 V2. The only two modifications i had to do was with the raptor tail pulley on the Jr tail output shaft, but that mod is very simple and a slight modification to the end of the raptor tail boom, but that was just as easy.

Now i went and tested this out today and wow, this is sweat, very very smooth running and maximum tail throw in both directions. It has turned the R50 tail into and exceptionally precise tail, and i have to say she fly's superbly, much better than before. Of course this is just my humble opinion but i certainly think it was well worth the extra cost and the little time it took to modify and put together.

Pictures below have just been uploaded, so might not show just yet.

Regards
