I've just started building my first R50, and am confused as to how the starter works. I seem to be able to spin the starter shaft either direction, I can hold the clutch bell and still spin it. How on earth does it turn over the engine? I've read that the bearing on the bell is a one-way, although the bell/bearing was preinstalled when I got my kit. All I had to do was to screw down the pinion, and install it.

Does it just work by friction?, if I put no pressure on the clutch, then it will turn slightly when turning the shaft, but I just cant see how it's gonna turn an engine over.

Could someone please enlighten my probably ignorance as it's annoying me. I dont like not knowing how something works when I'm building.

Cheers

Andy

OK

The starter shaft will rotate in either direction when there is no engine and clutch in the heli.

The starter rod that protrudes into the bell goes into the clutch which is attatched to the engine. The clutch ( black thing that fits on engine shaft) has a one way bearing in it, not the bell. If you install the engine and clutch you will only be able to turn the starter shaft in one direction easily. The other direction should turn the engine over.

There is no one way bearing on the bell. Hope this helps.

It may be worth you looking at this if you want to understand how the bearing works. The bearing in the clutch works on exactly the same principal as the auto bearing described.

You may want to take a forray to http://www.raptortechnique.com and study his build manual for the Rappy. Its an awesome supplement to the TT manual.

I've already downloaded and printed that out. Thanks for the info though. The manual certainly is, how should we say, CRAP. I really couldn't believe how bad it is. I would really have struggled to do it so far without the raptor technique manual.

I actually find the Raptor assembly manual very adequate.
The exploded drawings are very good. Just take your time. All the information is right there.
The RaptorTechnique site is also good reading when it comes time to do the setup.

Exploded views are fine if you've built a couple. I don't know how many times I would have had to take stuff apart and start again if it wasn't for Raptor Technique. Little things that the manual fails to mention, the order to put things together etc.

I built my first heli - a raptor 30V1- from the kit (not ARF) straight from the exploded views in the V1 manual. No problem at all, I think they are great. In the V2 manual I find it sometimes hard to distinguish parts on top of each other but otherwise I like the compact exploded views.

hey
the TT manual i definitly think is adequate.....
http://www.raptortechnique.com just helps to clarify and states things crucial like locktite, starter coupling mod, and stuff like that......that just make the build more enjoyable and you know your doing it right


Thanks
