  1. Thanks to all concerned for organising this weekend's Skeggy venue : In no particular order , The Fox bros' , Skeggy Model Club , Martyn , Stevie D , Mr Motorhome Man ( who provided very welcome hot drinks ) et al' Particular mention - must go to the Landowner and His extremely pleasant Wife & Family whom my Wife & I were very pleased to meet , not only allowing us the use of Their property, but mowing a fresh flying strip and parking area as well. I feel sure that we all conducted ourselves accordingly , causing no offence to anyone , which appears to run hand in hand with F3A Flyers / Events in general , albeit Classic or Modern. Nice to see quite a few familiar faces , and a few new ones too , some travelling considerable distances despite the rather damp conditions. It would be very nice to return there , and sincerely hope this may become a regular venue. ? Cheers.
  2. Posted by Andy Green on 23/04/2015 10:00:11: I too vote for an informal schedule. Would appreciate a caller but no judges. A " Advisor - Mentor -Observer " are possibly more genteel way of putting it Andy , there is a wealth of experience within the UKCAA to provide just that . Nobody is on trial , but you are testing yourself , and it may help to try and adopt the mindset , pre - flight, that you are actually only competing with yourself , since you can have no influence on the other pilots at that time. nor they - you. so why sweat , you will always want to do better .for your own sake. Friendly Critics . since a few check - sums and scoring protocols have to be in place if only as a guideline to anyone's progress. Though the best Flyers are not always the best communicators , there are plenty here who are pretty good at both .( I do not include myself) Maybe an intended base - schedule could be published ? I only have personal experience of " trying" to fly the turnaround manoeuvres, which I vastly prefer , and it saves time and fuel .Not that I have any competitive experience in pre - turnaround. AS always , when the flag drop's the Bu......t stops , and it is entirely natural to have a few wobbles stood in the Pilot's Box. talk is cheap. May I mention that , as purely an observer , the recent Skelbrooke event whereby Minty chose to expend some wonderfully aromatic fossil - fuel, surrounded by a veritable plethora of bunny huggers , the whole event was a very friendly , low key and laid - back affair , which although they ( the Pilots) are most certainly being " judged " must have helped. The key point being there are Members , Flyers , and...... "Judges" who know how to talk to people , and have the relevant bona - fides , given the chance. * Sam has put first - foot forward , and like S.D says , you need only ask . It's the subterranean loops with half - roll that confuse me. Absolutely agree to having an aim in your flying ( which is far from a boring routine) gives most flyers a new impetus , and generally stops the " what shall I do next " lethargy. Each to their own. Cheers.
  3. Very Impressive British Engineering Sam - Owdlad , and a lasting legacy ............ Proper metal geared servo ? Hope yer tightened t'prop nut .
  4. **LINK** Try this Prop Martyn . listen to the crowd , they luv it .................. Might slow yer down a bit ? F3A Thai - Style . Bet Owdlad made one er these as n'apprentice.
  5. Q. for like between the same size electric & & ic prop you will find the current draw will be significantly higher for the ic varient of prop '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' Eyup Owdlad. An I.C Prop has to withstand the " knock it on the Head " bash of combustion ( double hard with a 4T) along with the violent acceleration / deceleration of the piston and other reciprocating masses , plus the variable torque / rpm loads , hence its Mass / weight . A sparky thing , apart from the ( possibly) odd violent stop / start has much more of a " constant " since its torque is a consistent at all rpm. , which in turn affords a much lighter , more efficient prop . . which may explain why a leccy ' will fly smoother at slower speeds than an I.C , even if its overall model mass / weight is the same . The torque load is largely irrelevant, it's how the load is delivered what counts. e.g . A V -Twin Motorcycle will devour it's drive chain ( because of the irregular and violent power pulses ) than a relatively smooth - running in - line 4. * Increasing the rpm on an I.C magnifies this effect , but to the human ear it will sound smoother .
  6. What's the rpm on that prop Martyn . ?????????
  7. Sam , Please do so . your build blogs / skills are enjoyed by many captive - nuts ...........
  8. Hi Martyn. No actual user experience on this motor, my observations stem from common interest., not a critic either. Used a tuned pipe many years ago ( correctly called an expansion chamber) as you know. Wealth of experience amongst F3A flyers , not always on here though. try to add a couple of links just as a general guide , not teaching egg sucking. **LINK** **LINK** It may be fair to say that unless you are able to alter all port timings - width - height - shape to suit a particular application , you are left chasing the effect rather than the cause .. Bit off topic - but related. Eons it seems , ago. we sent most of our( motorcycle) barrels away to be ported which often involved new pistons , apart from taking a file and die - grinder to a few Bantams , Lambretta;s etc. remember crankcase stuffers ? Manufacturers regularly try to re - invent the wheel in order to gain market share , an example of this is when we ( Joe Public) were allowed to walk around the pits at race meets . circa @1976 I I was lucky enough to examine Mr Sheene's new RG500 square 4 with it's fairing removed . , the motor looked like 2 x stepped twins joined together in a square-ish layout , and looked vaguely familiar . Fast forward 40 - odd years , and the net' - via Wikipedia & Motorcycle News revealed it was effectively 4 x MZ 125cc's joined together in a stepped 4 config.now produced by Suzuki. In a very minor way , I was able to help out some of the penniless club racers ( we all were) by cutting apart their expansion chambers periodically , in order to remove the accumulated baked on clag & oil , then rewelding by hand. Sometimes the lads wanted the design modifying to their own design( at their risk ) where they obtained the designs from was a closely guarded secret , exept that everyone journeyed to Louth on a regular basis , and produced improvement on occasion , accompanied by 100% terror for fear of seizure , on all occasions. bore and length of the stinger .having a marked effect , a few mm. the wrong way and you ( they ) were kissing tarmac. We were the complete inverse of restriction , and despite this planet's bunny - hugging fraternity I don't think we have seen the last of the 2T strokers quite yet , I hope. You are not alone Martin, in relishing the mournful wail of an on - song stroker and I hope you can make this motor work effectively . at a more moderate rpm. As a long time customer of MCN, I was a bit alarmed to read last weeks 60th Anniversary edition , and staggered that I had been a punter for 42 of those years , Time & Tide innit . I watch , ask and learn with great interest about making a fundamentally wrong tool for the job - operate . some of your fellowes employ un - standard piston / liner combinations in their own motors , which is encouraging. Be interesting how the disc valve induction works with a pipe . Never mind, you can always put a 2CV engine in , and listen to Mantovani records between flights ? that should please the bunny - huggers , who's numbers will be reducing due to toxic waste from used batteries ? Thin Lizzy does it fer me. Vive Le Revolution . Cheers.
  9. **LINK** Interesting Concept , This link may help Martyn ? not an expert myself. The usual U.S.A pedal to the metal style of flying appears to predominate ( mega -Rpm ) was ( sadly) curbed over here many years ago. the rest you know. Many fond memories of watching the F3A Guys extract every last rev out of their motors ............ I notice in the UKCAA photo - thread ( which is excellent reading ) that a few individuals make reference to employing an " O.S V " motor , in happier days past. Your " Timing Disc " has some happy and , sometimes painful memories from my own motorcycle days . The O.S " badge " engineering appears to be very confusing over different world markets . I had to read a few threads to try and understand , and still not sure , of the subtle differences twixt an O.S >V, VF, and VFR motor ? As a very wise Flyer has previously mentioned , who has considerable mechanical expertise over many years of competition flying, although his dress - sense is questionable Hi - Sam. T'Owdlad Workable r.p.m range may be very narrow ? for most * reasonable purposes anyway. Maybe put the power setup on a test rig using larger / higher pitch props ? before you start chopping further lumps out of the header ? I wonder if anyone reading this Forum has actual - user experience of using this particular engine themselves ? Be great if you could get it workable on @~ 10K r.p.m , unless you have access to a suitable flying site. Good Luck.

  11. Wow ! Mr W. great models that have certainly found a worthy owner / flyer . ( not a none - modelling profiteer) Bravo.
  12. Hello Nigel , and thank you for the information , it's nice to hear it from the Horses - Mouth . so to speak. Yes, I was wondering if it was " pukka " F3A ( for its time) , No matter to me , I just like the Retro - Style , and it possibly being un - common on this side of the pond. Neither do I have any experience of flying the older Retro;s , or indeed competition flying ( apart from A.H's inaugral Npod at Gainsbro' some years hence , which was fun) , a few DSM's . Joker etc. was about Spring Chicken I ain't , Competition Standard - defo not, hoping to improve ? possibly . have fun trying ? Certainly. Slowing down without a tip stall rather than ballistic landings will do fer me mister ! A very wise owdlad has recently reminded me that it's the Pilot that makes the difference . As if I needed any reminding ! * It is actually a " King - Kobra " it's me that is unable to post pics properly . I did come across a " Kobra " picture, which appears to be a 40 - size ? with a fully built - up wing , not foam . and was , as you say , Identical in appearance to the Larger " King"  I always defer to those with actual experience , and welcome their input . Regards. Android       Edited By Peter Android on 10/01/2015 19:58:45
  13. King Kobra . Anyone Built or Flown one of these ? Were they 1960's - 70's ? Cheers. Edited By Peter Android on 09/01/2015 22:53:17
  14. Cheers Martyn & all the Crew . thanks for your efforts . * I hear some Yorkshire members are asking for a discount ? I can send bank transfer details immediately
