G'day folks

Went out to our field today with my brand new 50V2 with high expectations. Firstly I couldn't start the motor and whilst doing so must have created a small hydraulic lock. This in turn must have loosened the crankshaft nut causing the fan unit to shift upwards a couple of millimetres.

I thought I had siezed the motor or broken something because the cluth was rubbing on the top of the clutch bell which prevented the motor from turning over.

Much relief when I stripped everything down when I got home. After another application of locktite to the nut perhaps I'll have better luck tomorrow.

Cheers

Ahh sorry 2 hear this m8 just keep at it the same thing happened to me. Just make sure the fan and night are nice and tight. A crankshaft locking tool is good for doing this or i use a set of rubber handled pliers in the engine intake.

Too right, I noticed today that the crank nut was quite a bit lower down the crank threads then when I first tightened it. Probably a case of not wanting to be too rough with the new motor.

Thanks for the encouragement.

Do you have any experienced heli guys around to make sure it is all set up right? Helis can be a lot more chalanging to fly than most think. a littel experienced help can make a world of difference.

Sipper,

When I started out with helis, it seemed I did more fixing than flying!! It takes a while to get the bugs worked out of a new machine. Once you get the machine dialed in, and little preventitave maintenance experience, you'll be able to concentrate more on the flying, and less on the mechanical. But for me, a lot of the mechanical troubles I had were a great learning experience, as I didn't have a lot of help when I started, I learned a lot by trial and error. (lots of trial - even more error)

Hang in there!!!

Weyhey, went out to the field today and had a look at the small airscrew settings on my TT50, and found it was 9,5 turns out...... Changed this to 4,5 and the motor fired up first time.

Put 4 tanks of fuel through it today between letting a local guru check it out for me, and me hopping it around the site.

The best part was finding that the only trim required was a couple of clicks of down. Makes the Raptor manual seem pretty good.

Hi Sipper,

I just got into helis about a month ago myself. I started with a Raptor 50v2. I have had good luck with it and I am now getting into forward flight. I think 99.99% of my success is because of http://www.raptortechnique.com/. I followed the instructions on this web site in detail and everything worked out well. I still refer to all the time when I need setup info etc.

Thanks

Hi Guys

My main reason for getting the Raptor 50 was because both sites I visit are 99% Raptor, and whilst I quite enjoyed learning on my Venture 30 I really wanted to move up to a 50 size heli, and it was easier to go with the flow.

At least now when I want to know anything all the heli blokes know what I mean, and I can sneak a look at their setups.

I've flown heli's for years, my last being a Shuttle ZXX. I used to fly it, clean it, take it home, charge & repeat for a couple of years with virtually no problems. I come back to heli's after a few years off and decide to go for an R50, pretty much for the same reasons. So far I'm lucky to get more than a couple of flights without something, not always my fault! The clutch retaining screws sheared on its second flight, then I found RunRyder and found I wasn't alone.

Don't get me wrong, I'm very happy with it most of the time, I even stuffed it inverted into a gorse bush and got away with a bent feathering spindle and a couple of links (plus the blades of course) and repairs are soooo cheap. Yesterday I was trying out my new CSM Revlock governor and just tweaked the main needle a couple of clicks on the carb. Hovered a while, all okay so off on a circuit. 40ft up and the engine dies, coughs then picks up - but no drive. One hard landing later (feathering spindle plus the obligatory blades again) I manage to kill the engine and figure the clutch bolts had failed again - they were fine. Took the blades off and ran it up - clutch working fine. After a think and a talk it looked like I had over leaned out the engine and when it coughed it had started backwards, the other suggestion was the auto clutch. After straightening it out I took it back out this afternoon, started it up and it had started up backwards again - is the OS 50 hyper prone to this?
