Don Fry Posted March 28, 2016 Share Posted March 28, 2016 i have just acquired a tyro pilot. He has a perfectly good Ben Buckle 3 channel Ben Buckle super 60, a loft find. Have just spent the afternoon sorting with him, but I have no centre of gravity information. It balances at about 20 percent at the moment, bit forward methinks. Any one know where the CG should be. Weather window on Wednesday, and want to make a 10am maiden. Quote Link to comment Share on other sites More sharing options...
Peter Christy Posted March 28, 2016 Share Posted March 28, 2016 From what I recall of mine some years ago, it should balance on the lower main spar. -- Pete Quote Link to comment Share on other sites More sharing options...
David Davis Posted March 28, 2016 Share Posted March 28, 2016 According to "The Outerzone" the c of g on the Super 60 should be just behind the front lower spar. Quote Link to comment Share on other sites More sharing options...
gangster Posted March 28, 2016 Share Posted March 28, 2016 Ben Buckle plan shows it 3" from leading edge which agrees with both above To be pedantic about half an inch behind the centre of the spar Quote Link to comment Share on other sites More sharing options...
Don Fry Posted March 28, 2016 Author Share Posted March 28, 2016 Thank you very much. Also on reflection I have been a bit cavalier about control throws. I have set them at, elevator, 6mm reach way, and rudder, 25 mm each way. Looks sensible, anyone know? Quote Link to comment Share on other sites More sharing options...
David Davis Posted March 28, 2016 Share Posted March 28, 2016 She'll be right! What's the engine? Quote Link to comment Share on other sites More sharing options...
flying pastor Posted March 28, 2016 Share Posted March 28, 2016 Sitting at home feeling sorry for myself suffering from sciatica I have both s60 plans in front of me, ben buckle 60 shows control movements as 20 degrees both ways or 14mm each way on elevator and 25mm each way on rudder. Just contemplating a new build either bb60 or kk60 (they do differ in places) or even the lead sled that is called the New Super 60. Hope the control movements help... Chris.

Don Fry Posted March 28, 2016 Author Share Posted March 28, 2016 Pastor, thank you. Do not sit. Get down on the floor, and do single leg lifts. It will sort the back problems. I will return the elevator to how he had set it, and pretend I had further cogitation on the subject. Many thanks, poor bloke had worn himself out trying to get this information. Engine is, I believe an ancient VECO 40, air bleed carbi. Runs ok Quote Link to comment Share on other sites More sharing options...

Peter Christy Posted March 28, 2016 Share Posted March 28, 2016 The Super 60 is very tolerant of both C of G and control throws. It doesn't need much "up" elevator, but does need quite a bit of "down"! Remember, it was originally designed as R/c OR Free-Flight!! Mine was flying back in the 60s on a Merco 35 and six-channel "reeds" (non proportional, 2 channels per function!). Even so, I fitted a bigger rudder to get the desired control response! On modern gear, they are very docile, almost too much so. -- Pete Quote Link to comment Share on other sites More sharing options...
David Davis Posted March 28, 2016 Share Posted March 28, 2016 I had one fly away when a wire failed in the 35 meg transmitter. They free-flight quite well! It was rescued by the RAF. Quote Link to comment Share on other sites More sharing options...
Peter Christy Posted March 28, 2016 Share Posted March 28, 2016 Yes, mine free-flighted when a receiver DEAC failed! It was out for a fortnight, but I got it back totally undamaged! It had made an almost perfect landing in a field of corn. The farmer just spotted it in time, before it vanished into his combine harvester...!!! -- Pete Quote Link to comment Share on other sites More sharing options...

Don Fry Posted March 28, 2016 Author Share Posted March 28, 2016 My tyro has a trike version. Very nice front leg. Rubbish rivets. He is a retired joiner by trade, so one simply issues instructions and it gets done. Quote Link to comment Share on other sites More sharing options...

David Davis Posted March 29, 2016 Share Posted March 29, 2016 A better trainer, with that flat-bottomed Clarke Y aerofoil section certainly, and able to fly in a breeze, but I prefer floaty free-flight characteristics of the Junior 60 myself. Best of luck with the maiden. We wait with impatience the story of the maiden flight. Quote Link to comment Share on other sites More sharing options...
Don Fry Posted March 29, 2016 Author Share Posted March 29, 2016 Maiden put back to Friday, Saturday, as weather window for Wednesday has disappeared. Not too worried as its a very decent airframe, and my tyro has very decent craft skills so his restoration is good. Thank you David for the photo. This example has some glass reinforcement in the avionics bay, and I now realise that it was once a tail dragger. So we will be able to use the airframe in both modes. I assume the aileron wings for this aircraft is the same wing without the dihedral, so I will get him to make a aileron wing and get all the variants done.

Fun Flyer Posted March 29, 2016 Share Posted March 29, 2016 For me, flying the Super 60 is just what its all about! I always have one to hand. The plan for the aileron wing is here; **LINK** Quote Link to comment Share on other sites More sharing options...

flying pastor Posted March 29, 2016 Share Posted March 29, 2016 I've enjoyed reading this whilst rather under the weather. Here is some more info. If you read the booklet, Radio Control Big Four, which is a free download it shows the wing section as a modified Gottingen 549 and also that a standard Super 60 can be modified to a tricycle U/C. My last '60 with an ailerons wing had approx 1"of dihedral under each tip, just enough so that it didn't look "droopy". Reminiscing, as one does here is a list of the '60's that I have owned over the years. 1. junior 60 free flight with ed racer power...1963,ish 2. Junior 60 RC am35 power and s/c carrier wave valve RC 3. Kk mini super ed racer and home built galloping ghost eqpt. 4. As 3 but with enya 19. 5. As 4 but with rcme digital proportional radio and fox 35 motor! 6. Super 60 with enya 29 and later fitted with os 40. Various radio. 7. Super 60 electric with speedgear 700 and 14 sub c nicads. This weighed about 7.5 lbs but still flew well! I later fitted it with an axi motor and 10 cell nicads. Finally...8. a 75% super 60 with mfa belt drive 540 motor and 7 cell NiCad. Guess what, without exception they all flew well. Perhaps its time that I built another '60 I've still got the tail wheel assembly from the last one! Enjoy your 60's. All the best... Chris N.

Don Fry Posted March 29, 2016 Author Share Posted March 29, 2016 Thank you pastor, much good information. Re buying things, my tyro is a craftsman. He sees no reason to spend one penny on ARTF, when he can make it. Give him some time, and if he progresses, I will sort an aileron plan, or draw one. I also had a Junior 60 in the mid sixties, ED Racer powered, Elmic escapement, and an OS PIXIE radio. Quote Link to comment Share on other sites More sharing options...
David Davis Posted March 29, 2016 Share Posted March 29, 2016 Posted by gangster on 29/03/2016 15:48:46: You can also get the aileron conversion kit from Ben Buckle It's such a shame that Penn Models, which used to produce a four-channel Super Sixty with inset ailerons to order, no longer make them or even supply the plan. They were nearly all finished in Cub Yellow and red Solartex. This was mine, KIA when I flew across the disc of the sun, I got disorientated and put in the wrong controls.

Fun Flyer Posted March 30, 2016 Share Posted March 30, 2016 I've been flying the same Super 60 for almost thirty years now. I've just replaced the fuz and wing a few times but the undercarriage and tail wheel are the same. I'm actually considering building a new wing for the current one with inset ailerons and flaps. Has anyone tried that? Quote Link to comment Share on other sites More sharing options...
Dai Fledermaus Posted March 30, 2016 Share Posted March 30, 2016 Your Super 60 reminds me of Trigger's broom Fun Flyer. He claimed he'd had the same one for 20 years during which time it had 17 new heads and 14 new handles. Quote Link to comment Share on other sites More sharing options...
flying pastor Posted March 30, 2016 Share Posted March 30, 2016 Fun Flyer, I think that is a brilliant idea. Inboard flaps and outboard ailerons. Give it plenty of power with a large diameter and fine pitch prop and you could end up with a Super 60 Fun Cub. On windy days we used to hover our 60's into the wind and have great fun. They handle the wind surprisingly well. All the best.... Chris N. Quote Link to comment Share on other sites More sharing options...
