I purchased this Raptor 50 with an aftermarket head and tail. The Head looks like a Kasama hub and miscellaneous upgrades added? The tail box does not match anything but the blade grips look like Kasama. I am having trouble with the tail and need to check the assembly but without any schematics? Any help would be appreciated.

not 100% sure but the head looks like a G-Force tuner head and the tailbox is almost certainly a Quick UK one.

Just noticed the spindle shaft has what looks like HT on is in a floral wreath which would make it a Hobby Taiwan head.

Would you know where I may be able to get a schematic for the tail!

not sure such a thing exists but you could always try emailing Quick UK - what exactly is your issue with it? The reason I say its a Quick UK one is it doesnt have a tensioner pulley as they dont need one the way its made.

Thank you. You hit the nail on the head Oz Phantom. The Heli has an odd minor shake and the tail hunts. The Tail belt rides against one side of the pulley and it seems to be unstable. It was sold to me as having a Kassama head and tail and after looking at the Kassama schematics I knew It was not. I just want to get the bird flying stable like my sons.
Thank you again for the Help!

Might want to double check you don't have an extra twist in the belt and that it has enough but not too much tension in it. Also make sure the linkage is running smooth with no binding without the servo connected. Just some other things to double check if you haven't already. Good luck

beating the air into submission...........cool!

Thank You dcbusdriver

The belt is o.k. and I will double check the tension. After disassembling the tail I found the bearings to be a little rough. I will replace them. Also after disassembling the head I found the blade grip bearings out of order. The Thrust bearing was the last bearing(towards the outside, blade) instead of inside. I do not know what kind of effect this would have on the head but I would think it could setup the head shake and instability I am experiencing. As the thrust bearing has no side force control of a radial bearing the blade grip would deflect on any side force, (ie. a change in pitch or cyclic). I will check the bearings in the AM and reassemble them in the proper order.
Any Thoughts!
Thank you all

The head block is Kasama
All other metal had parts are Mavrikk

Have it almost sorted out.

Have sorted out most of the issues with this bird. The bearings in the tail shaft where bad. Replaced bearings in the head as the original owner had the thrust bearing on the outside of the blade grip. I thought the main shaft was bent and replaced but after checking the original with my dial indicator it is spot on. Now I have a spare. I reassembled and test flew the bird. Now it is smooth and the tracking is great but the tail hunts. Took it over to Rob at Cherokee Choppers (cherokeercchoppers.com) and he adjusted the tail servo. It is better but still hunts. We are getting there. It is amazing how much things have changed from the 80's!
I want to Thank everyone for the help!

Doug, to replace bearing from the tail case...
What did you do?... reheat?... just pull them apart?

My raptor have one of this tail case and I was wondering about decolorate because of reheating...

Replacing bearing in the QuickUK tail Case

To replace the bearing in the tail case mine where not tight. I was able to remove them with a firm press of the thumb. However, I have come across similar situations where heating was necessary. To remove a bearing in an anodized aluminum casing, heat it in an oven (or toaster oven) at about 250 degrees. This should expand the aluminum casing and allow the bearing to nearly fall out and should not discolor the aluminum. This also works with removing the bearing in any casing, such as a crank case. Just a word of caution, DO NOT USE THIS PROCEDURE WHEN THE WIFE IS AROUND. Side affect are never mild and can include, head aches, blurred vision (from a blunt object striking the back of the head), chills (from sleeping on the couch) and has in some instances caused death.
Hope this helps
