Guys,I have a Schluter Champion 60 size inside of a two piece Twin Star fuse. can I up grade the head to something else incase of a crash? I really don't fly this one because of parts are hard to find.

measure the main shaft diameter and then find another make of head with the same dia it will work

i have a morley bell 47 with a shuttle head , but it does run a modified shuttle main shaft to fit into the morley main gear

The main shaft is 10mm so the options for alternate heads seem endless BUT, the collective control system on most of the Champions is based on a system using a pitch control wire running up a slot in the shaft. If your Champ is equipped with the "System 88" control system (swashplate slides up-and-down with collective inputs), you're all set. If it's the System 80 control using that sliding wire, your options are very limited.

The metal Champion head is pretty tough. Bearings are standard except for those in the mixing arms, feathering spindle is 8mm and could be replaced with one from a current heli, same with the flybar and its parts. It would take a really bad crash to completely trash the head. Be careful, make sure the machine is completely reliable and don't go cheap on the electronics. Have fun.

The swashplate only tilts, the shaft is slotted for the short rod that control the blade pitch.

OK, that's better...

With this control system you need a head with the same collective mixer bar as the original head. I sure can't think of anything that will work without some custom machining. Anyone else?

Kalt used the pitch wire running up a slot in the mainshaft. 10mm dia mainshaft. What about ECCPM with a Predator head.

making a modern head assembly

If I wanted to make the head modern, I don't know where to begin. all of the heads I have seen,the swashplate slides up and down the main shaft.my swash pivots on the main shaft.

just look at where you can fit any bell cranks to operate a sliding swash plate
or re-postion the servos to around the cetre of the mast to have direct eccpm mixing

Now here's a problem of sorts - making lots of changes in the Champion leaves you with "less" Champion. Unless it's your only heli and the point is to modify it so flying is the most important thing, it's best to shelve the Schluter and fly something still in production.

The real reason to fly the Champion is because it IS a Champion, not just another heli.

Like I mentioned earlier, there was a later version using the System 88 controls. This used a different servo tray with the two cyclic servos on rockers moved by the collective servo. The swash was driven via four bellcranks situated around the base of the mainshaft. With this control system almost any modern head will work. I don't own the System 88 Champion so I can't provide part numbers or pictures but someone out there should be able to help.

Bob (Heli-Star), are you reading this? You've had bunches of pre-Robbe Schluters, can you advise on the System 88 version of the Champion?

I have all of the heads that Schluter released all the way up to the Scout.

Unfortunately, I agree with HHC, why not just get the entire mechanics from a different (new) heli? (Century 50 size scale mechanics are under $300)

To upgrade to something current, you will have to replace everything from the swashplate up (to allow it to move). This will require a series of bell cranks to get the controls back to the servos. By the time you do all of that, you probably are not saving much.

But, if you really want to do this, I will post some pictures for suggestions...

I have three scales including this one and three pod & booms that are current. but I like this big schluter, it has a wire that turns the tail rotor and the helicopter is heavy and stable. but if there is a way to upgrade the head with out spending a lot of money I would like to do it. the heli is in excellent shape and I would like to fly it more without worrying about trying to locate rare parts replacement or I may just get rid of it and get another current scale.

Head

Everyones comments here are great tools, you guys covered it all. I don't fly scale, I think the Champ. would do great either way. Vince C. from the old Heli-Pad here in S.Jersey flew a Champ with the old Mech. in a jet ranger, and it flew great. Parts are still out there in case of a crash. When I fly Schluter, I like to fly org. as best I can. Just my 1.5 cents here.
