    Hi Ken,

    Thats very kind. Thank you. . I was just really looking for something to do as the weather has not really been any good for sloping for weeks now.

    Can anybody confirm the actual issue that the article was in? I can then at least get it all set up on a test bed.

    Rod.

    Thanks guys,

    As a retired GP i have seen the spectacular damage an engine can do!!!

    Thought the OS H-MAX might raise some enthusiasm. Will read the article again and then make a decision as to..

    "Give it a whirl or go to Phil's Models in North Shields but its 50 miles away, but so is the nearest major hospital come to that!

    Nothing like living in the sticks.

    Many thanks for your prompt help and advice

    I read an article in my collection of RCMEs showing you how to how to set up and start and run an IC engine but can't find it . I usually fly electric but was given an OS MAX-H 40 and a half built old trainer that was in someones garage which I thought I might have a bash at. Ive got the fuel ,tubing, starter kit and a chicken stick. Can anyone tell me which issue it was in? Must be last 2 years I think. Have searched index to no avail.

    recommend an easily progammable transmitter

    in Gliders and Gliding - General Discussion

    could anyone recoomend an easily programmable 2.4 transmitter for using on a 4 servo wing. I have a FutabaT6EX which will allow flaps and elevator mixing but I'd like to move up to a 4servo wing with progressive crow breaking controlled on the throttle stick.There are so many transmitters out there! I currently fly a middle phase,moth and easy glider but aspire to a 4 servo glass machine.

    Thanks guys. I sorted the problem by using an old micro servo and soldered a couple of bits of copper strip into the circuit , one on the servo arm and the other onto the top of the servo casing making a very satisfactory on/off switch!! works well!! I am using a seperate battery for the lights . I like the Turnigy switch Gonzo suggested. Many Thanks, Roderic.

    switchable landing lights

    May2011issue describes a circuit forto operate retracts . I thought I would use this same circuit to operate my landing lights ie substitute the landing lights instead of the retract servo. I have done that but find that the lights won't switch off. When I use the main on/off switches ,I can switch the lights on and off whilest still maintaing power to the main servos. I have tried using both the gear and flaps chanels on my Futaba6EX transmitter to no avail.I have removed the positive as shown and have both circuits swithed ON but still no joy. Any ideas Rod Craig

    Middle Phase - torque rods OR wing servos?

    in Gliders and Gliding - General Discussion

    Posted

    I have read Andy Ellisons article but must confesss to still having difficulty undertanding how the torque rods fit to the single servo and how easy it will be in the field to attach wings and linkages.I am holding the wings with rubber bands. I fitted wing servos and ailerons to my Easy Star  glider which worked very well. If I was going to abandon the torque rod way could someone advise on a suitable servo size please.Would you need a special servo mount chamber too? Has anyone got a diagram of torque rod connections .... always think one diagram is worth a thousand words!!

    Is this power train OK?

    in General Electric Flight Chat

    I've just built a Multiplex Gemini with Multiplex C3516-1130 Tuning Motor  with10by5 prop. which pulls30A,max current 48A and 350W. I have a Phoenix 45ampESC. I intended to use a 2200 3S Evolite but got seduced by their Eon X30 advertsinRCME but now I'm anxious as they say it pulls 66amp continuous at 30C. I took it out for its maiden flight today and went really well but never on more than half throttle. Should I have a bigger ESC? I,m relatively new to electric flight.Could you advise and prehaps point me in the direction of any articles that may help my understanding of power train set up etc. I think a wattmeter may be a good idea to see what's really happening ! Best Wishes, Roderic.

    Dear Bert,
    Thanks for your comments.We seem to be talking at cross purposes here! You agree that Cof G forward , into dive, release elevator and dive gets worse so you have to up elevator to maintain level flight path,which is just what the guy in BMFA was saying.
    But look at page52 of RCME, middle column "with forward CofG, will begin to pull out of dive....as if up elevator had been applied" but surely that contradicts what you have just said. Any rate what is the point of Andy's article? My Easy GliderPRO has the Cof G where mulptiplex say it should be and flight is level.Is the idea that when slope soaring in strong rising air current that by adjusting the Cof G for those conditions that you can keep better control? Id love to hear from you further, Roderic.

    I dont follow Andy Ellison's explanation.Surely if the Cof G is forward the plane will continue to dive and if its aft of the correct position it wil pull up! Or  do the Laws of Physics not apply to gliders in a 45 degree dive? If you add weight to the nose it must go down and towards the rear it should pull up! Is Andy Ellison wrong or am I missing some other factor. Certainly the BMFA  article to which he refers seems  the correct one to me!! I await an explanation from some aerodynamacist   Roderic.

    Elapor primer

    in All Things Model Flying

    Posted

    Iwas rather surprised to find in the instuctions with the primer that it can soften and distort  the elapor . Anybody got experince of using primer? Would you paint all the surfaces before assembly. Will the primed and painted surface still glue satisfactorily with Zacki? Love to hear from someone whoose done this, Rod Craig
