Matt Posted May 16, 2009 Share Posted May 16, 2009 Hi All Due to the limited sizes and price of backward props, I was wandering if it was possible to run our little two strokes backward? Some of mine do fire backward when starting up but run as rough as a badgers backside. Just an idea. Matt Quote Link to comment Share on other sites More sharing options...
Myron Beaumont Posted May 16, 2009 Share Posted May 16, 2009 No Except engines like the old Mills with rear induction etc (Gets complicated to explain ) but its to do with timing of the ports married with the timing of the induction point ie when the crancase low pressure sucks fuel in to put it crudely .On engines as I said like the Mills this point is independant of the position of the crankshaft angle at which a front induction process happens in ONLY one direction . Hope this highly hopeless inadequate explanation helps a bit Myron Pheww ! Quote Link to comment Share on other sites More sharing options...

Matt Posted May 17, 2009 Author Share Posted May 17, 2009 Thanks Eric I'll have to have a look through my engine collection when I get home and see what's possible. As for electric...wash your mouth out...go and sit in the corner and stop being so silly . Quote Link to comment Share on other sites More sharing options...
Myron Beaumont Posted May 17, 2009 Share Posted May 17, 2009 Well said Matthew -Don't listen to the dark siders -especially traitors Of course you can turn things round as long as it is physically possible but hardly an efficient solution for useable performance .I didn't go into detail as a designer works things out (timing /ports etc )to work properly .not so a bodger can reassemble it differently to just "make it run" When I'm in power soon & i have drawn up possible candidates tor my cabinet / shed . Their names will of course be Me as boss GRUMPY & others under the titles'of the other dwarves in that well known fairy tale (appropriate Eh?) I'll let my supporters decide who is who .Have to keep hijacking threads to drum up support .Latest name to be considered for my party is "The Spinners " Your trustworthy future leader - Keep up your invaluable support Both of you Quote Link to comment Share on other sites More sharing options...
Phil Claridge Posted May 17, 2009 Share Posted May 17, 2009 we'll have to watch that myron when he gets the top job and see how many saito's balsa wood and gallons of glow fuel appear on his EXPENSES oh! and cider Quote Link to comment Share on other sites More sharing options...
Myron Beaumont Posted May 17, 2009 Share Posted May 17, 2009 PHIL (Future shed / cabinet member) No good you being in my party if you don't trust me ! You can be assured there'll be no claims for lipos for sure -honestly ! Only electronic equipment necessary to control flying (namely Tx's Rx's & said powering accessories & servos -cos they do what they're told ) will be claimable in the field of electiontricity (election trikkery) -never really knew what it meant 'til now ! Regarding the items you mentioned they will of course be claimable by ic fliers ! Don't forget I make the rules once I'm in power . Hope our new "temporary "moderator Polycreep doesn't upset my campaign plans ? Am busy making out my manifesto & I can tell you now that one of the top priorities will be increasing and improving male order ( with maybe the exception of Gemma if she votes for me ) I don't want to be accused of bias . Dont' forget comrade ic fliers only ARTFAG .Keep up your support for the "spinners " party . At the last count I have almost four supporters -Keep up the campagn .Just a few more needed to pay for my deposit . Truthfully Would have been flying today had it not been for the poor in fact non-delivery of two receivers and that 'er indoors volunteered me to assemble the lady's next door flat pack bedside table (3 hours ) Isn't that the kind of leader you need ? No perks there of course Quote Link to comment Share on other sites More sharing options...
Matt Posted May 17, 2009 Author Share Posted May 17, 2009 Haven't you lot heard...there won't be a 'next election' to rig...I'll be leading a revolution against the capitalist pigs who tax my fuel and spend it on their husbands porno. Maybe if she wasn't so busy ripping us off her husband wouldn't need the 'blue movie' Talking of fuel...I've just watched a 'flaring off' on an oil rig for the first time...now that's impressive! What a heat...I think it was about ten years worth fuel for my car, planes, helicopter, house, shed you name it! Do you think they'll let me take some home?

Richard Duvall Posted May 17, 2009 Share Posted May 17, 2009 I would have thought that even if you could get the engine to run OK backwards, the profile of the prop would be wrong? Quote Link to comment Share on other sites More sharing options...
Frank Skilbeck Posted May 17, 2009 Share Posted May 17, 2009 Not if you turn the prop over, do this on electric pushers where all you have to do is switch a couple of wires around. Quote Link to comment Share on other sites More sharing options...
Matt Posted May 17, 2009 Author Share Posted May 17, 2009 "do this on electric pushers where all you have to do is switch a couple of wires around." But where is the fun in that, or the achievement, if I can get one of my motors to run backwards and make enough power to fly that makes my model even more unique. Yes your right, it would be much simpler, but I don't have the spare cash to to buy my way out of modelling challenges. And I LIKE playing with oily engines.

Myron Beaumont Posted May 17, 2009 Share Posted May 17, 2009 Matthew. I have decided you can have the lastest position in my cabinet/shed . From now on you will be known as "Happy" 'cos I say so .Still not quite sure about Doc-Sneezy-Bashful-Dopey -Sleepy . Working on it but Phil Claridge will definately be "Dodgy" Your honest modest non power seeking leader "Grumpy " Don't forget "ARTFAG" Pleased to report we now have four members so far. Trying to think who could be the "Snow White" of our new party ? Are you there Gemma ? All you have to do is be the centre of lift for my party and not gravitate to the front or back upsetting the balance Your leader in a week or two G-UMPY Quote Link to comment Share on other sites More sharing options...
Matt Posted May 17, 2009 Author Share Posted May 17, 2009 Your too kind G-UMPY Can I be minister in charge of guillotine? BTW Frank thanks for the reminder about turning the prop over...knowing me I'd have forgotten. It'll probably take a while to remember to flick the motor the right way as well!
