Peter Miller Posted June 14, 2012 Share Posted June 14, 2012 I started up my new model and while I was still in front of it my assistant began adjusting the needle valve which was set very rich. The OS FS 40 Surpass threw the prop which hit me on the arm and chest. Luckily I was wearing three layers including a thick fleece but I ended up with a nasty bruise on the arm and a lesser on on the chest. That is a two P piece. I was lucky, it could have been a hospital job. My big flight box has the starter built in and I am always behind the model but I use the small box most of the time as it is a long way from the pits to the car. At least the bruise on the chest got a laugh because it reminded me of the old song "Oh what a pity, she's only one titty to feed the baby on. Poor little bugger's only one udder to chomp his teeth upon" Quote Link to comment Share on other sites More sharing options...
Turbycat Posted June 14, 2012 Share Posted June 14, 2012 Not had one of mine come off completely before. Had my ASP 91 FS prop come loose when applying the starter, but it didn't fire up luckily. I have had to duck a couple of times when others have lost theirs in the pits. Andy Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted June 14, 2012 Author Share Posted June 14, 2012 Years ago a member's Saito 30 threw the prop. It hit his hand. Four stitches to close the vein and five to close the cut. I normally use the lock nuts but the Surpass shaft is not long enough when using a spinner.

John Olsen 1 Posted June 14, 2012 Share Posted June 14, 2012 Would it be worth trying some locktite in this situation when you can't use the proper lock nuts? John Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted June 14, 2012 Author Share Posted June 14, 2012 Loctite makes prop removal difficult.. Maybe it just was not tight enough. The main thing is STAY BEHIND THE PROP. Quote Link to comment Share on other sites More sharing options...
Cookson Posted June 14, 2012 Share Posted June 14, 2012 Ouch ! I had an incident tuesday night, a fella plugged in his foam-e and buzzed the engine up, he had it on a high table about chest height, facing me & about 6' to my right, I heard it turned to see what it was & promptly moved out of the way, as I didn't fancy having it in my chest or face. What was even more worrying was about 2 mins after he got it in the air the motor came loose & became detached then came out the front !!!!!!!

MikeS Posted June 14, 2012 Share Posted June 14, 2012 Very lucky escape there. In the last couple of months my 46fx has thrown the prop twice. First time was my own fault as I had not tightened up the securing bolt on the back of the exhaust and when vibration slowly work its magic the engine threw the back end of the exhaust off and the engine must have run backwards as the prop got thrown some 15 meters, I was at the back of the model at the time. Second time when I was starting the engine. the prop just jumped off on to the floor. Well at least you only got some bruises on your arm and chest. Got away with it.

Alan Cantwell Posted June 14, 2012 Share Posted June 14, 2012 I get fussy git looks when i insist on watchers getting behind the prop at the field, but having seen a lot worse accident than Peters, i will continue looking after their welfare, i can also remember a young hot shot being told, by a friend, that the 62cc motor he was running,had 6 bolts in the prop driver, and he was using only three, and they where stainless steel, looks of disparity went his direction, just 10 minutes later, the bolts sheared, and the prop flew about 80foot, now this would have HURT!! it was a 22x10 menz, always get behind the thing, as Peter shows, it makes sense,, no matter what size, my worse prop bite to date came from a cox black widow 049cc!!!! but that was my fault, not the motor Quote Link to comment Share on other sites More sharing options...
Lee Smalley Posted June 14, 2012 Share Posted June 14, 2012 allways go behind the engine as soon as she starts, ran my TT130 im my pitts last month, was my own fault but left the plug driver on and just as she reached full power she dackfired and threw the prop, it went off like a rocket towards the stream, everyone was saying the same things....ooo that was lucky!!! errr no just good habits !!!

Turbycat Posted June 14, 2012 Share Posted June 14, 2012 Crickey Alan that is seriously dangerous. I'd have told him in no uncertain terms what was wrong. Then if he insisted on carrying on I'd have asked him to wait until I was over a mile away! Andy Quote Link to comment Share on other sites More sharing options...
Alan Cantwell Posted June 14, 2012 Share Posted June 14, 2012 Didnt hurt, thats cos the pilot had moved all behind the prop, and rev ved it up when he too was behind it, at least the everyone behind the big saw thing had been adhered too Quote Link to comment Share on other sites More sharing options...
