Looking to buy a second hand 550 helicopter. I have seen a Logo 550SE for sale that looks interesting but I want to make sure that it is still supported for spares. By which I mean properly supported, still being made and distributed, rather than hunting around for shelf stock before it sells out.

Cheers,

Nigel

Thanks, have have been doing my own research and have discovered a potential problem.

For the newer 550SE versions they changed the head design so that there is more commonality with the 550SX. For example the main shaft for the newer versions is 199mm whereas the older ones are 205mm. The head and swash components are different too.

Mikada have deleted the old main shaft, maybe some of the head and swash components. So it is extremely difficult to get a replacement main shaft should you bend yours. MikadoUSA don't have it.

I don't whether it is possible to upgrade the head or what would be involved - does anyone here know?

Cheers,

Nigel

What head block do you have? Is it the one piece (SX) or 2 piece (old SE). Also are you positive that you have a 205mm shaft, and not a 211mm one. The SX version shaft (199mm) is designed to work with the one piece head, and is longer below the lower jesus bolt hole to accommodate the counter bearing for the motor shaft and pinion. The longer shaft is just taller.

Mikado makes a complete retrofit/upgrade kit that has the counter bearing, one piece head, main shaft, and all dampers/bolts/washers/shims. There is no change in the grips for either head block.

I have upgraded to the SX version on several of my buddy's versions. Keep in mind that the frames are common from the 550 to the 690. So it is easy (physically, but you will have a cost associated with the upgrade) to upgrade. I personally haven't gone any further back than the original 600 (no SX/SE designator), but all the parts are supported.

I don't have one at the moment, just looking at one for sale. Pretty sure it is an older SE.

My research has only come across 205mm and 199mm main shafts, not a 211mm.

Cheers,

Nigel

If you look at the manuals, you are correct it does show a 205mm shaft. I couldn't find one anywhere on their website, but they do show the 211, and the 199 ones.

As far as I can tell, the 211mm shaft is for the 600SE.

Still seeing the old SE versions use a 205mm which has been deleted.

Cheers,
