David Cooke 1 Posted November 12, 2013 Share Posted November 12, 2013 I built this 60" odd trainer as a kid in 1991. I put a Micromould sticker on the tailplane. Can anyone tell me the name of the model please? Just curious to look it up again. Quote Link to comment Share on other sites More sharing options...

Bearair Posted November 12, 2013 Share Posted November 12, 2013 Looks like a Tyro Major to me, but that would be 54inch however lots of DB designs were produced in all different sizes! Roger Quote Link to comment Share on other sites More sharing options...
David Cooke 1 Posted November 12, 2013 Author Share Posted November 12, 2013 Tyro Major. I think you may be right! If it is then that is a really spooky coincidence as I'm about to build the Mini Tyro......!!! Quote Link to comment Share on other sites More sharing options...
John Privett Posted November 12, 2013 Share Posted November 12, 2013 Tyro Major was my first thought too. I had one as my first r/c models getting on for 40 years ago. Quote Link to comment Share on other sites More sharing options...
Colin Leighfield Posted November 12, 2013 Share Posted November 12, 2013 David. I'm sure that is a Frog Jackdaw. It dates back to the 60s, was designed by (Cyril/Stewart) Uwins and I've still got mine. Very good and worth having. Luck you. Quote Link to comment Share on other sites More sharing options...
Colin Leighfield Posted November 12, 2013 Share Posted November 12, 2013 Looking again, the wing tips look more squared off than my Jackdaw, but it looks uncannily similar, particularly the shape of the fin/rudder and position of the tailplane. Where did you get the kit from originally? Was it new , if so it's not a Jackdaw but it's certainly interesting. Quote Link to comment Share on other sites More sharing options...
Bearair Posted November 12, 2013 Share Posted November 12, 2013 Look at the top of the fus from wing root to fin, either its curved or the angle of the photo makes it so. if it is curved it aint a Jackdaw like ive ever seen. Quote Link to comment Share on other sites More sharing options...
kevin b Posted November 12, 2013 Share Posted November 12, 2013 I have a Tyro Major plan and it is 45ins span. I also thought it should have been 54ins. Unless the plan is printed wrong, but it does say 45ins above the title. I also have a Tyro plan, which looks like the same airplane, but the plan layout is different. Regarding the photo. I would say by the fin shape and wing airfoil that it is a Tyro. kevinb. Edited By kevin b on 12/11/2013 23:11:24 Quote Link to comment Share on other sites More sharing options...
Colin Leighfield Posted November 12, 2013 Share Posted November 12, 2013 Maybe so Bearair, but if it's 60" it's the same size. Also looking around the nose area the top of the fus sides up to the engine bay are rounded off on mine, but at first glance it had the overall sit and air of the Jackdaw. Bob mentioned the Mascot but I don't recall what the span of that was. Quote Link to comment Share on other sites More sharing options...

John Privett Posted November 13, 2013 Share Posted November 13, 2013 Even if it was 30 years ago I'm certain my Tyro Major was a 54" span model. The Tyro was 45", the Mini Tyro is presumably a bit smaller again. This page lists the Tyro and Tyro Major and backs-up my figures. Quote Link to comment Share on other sites More sharing options...
Colin Leighfield Posted November 13, 2013 Share Posted November 13, 2013 I'm sure John's right. If this is 60" it's something else. Just for peace of mind I'll dig the Jackdaw out of the garage loft and have a gander at it, I keep on saying I'll do something with it anyway. I've got the plans for it as well.

PatMc Posted November 13, 2013 Share Posted November 13, 2013 Another vote for the Tyro Major. If you look carefuly at the pic the first rib in from the tip is easy to make out & it's possible to estimate where the rest are - I make it 9 per wing - which tallies with the TM whereas the Jackdaw has 12 pw. Colin, I've just been looking at the Jackdaw plans in Outerzone, never had the opportunity previously, it looks an interesting alternative to the KK Super 60 & I like the fact that it was designed with ailerons. I have a Frog 3.49 RC diesel & a single channel multi escapement plus a 3 posn throttle esc which would be bang on authentic for the period - but if I did get around to building one it would be electric powered with modern radio gear.

Colin Leighfield Posted November 14, 2013 Share Posted November 14, 2013 Hi PatMc and all other mates. The Jackdaw was brought out I think to compete with the Super 60 and in rudder/ motor/ elevator form had similar flying characteristics. However being designed by the guy who I think designed The Uproar etc. ( he was a Uwins anyway), in the aileron form I think it was more all round capable than the (excellent) Super 60 as well as being tough. The first test report I saw was I think in Model Aircraft, although it might have been Aeromodeller. They fitted it with a Frog 349 "Vibramatic", a reed radio set and I think they converted it to a trike undercarriage. I know that they had problems with engine vibration causing the reeda to play up and cause spurious commands, such as the engine going back to idle when set on full throttle. I bought mine secondhand in about 1972, so it was probably already about 10 years old and well flown but in perfect condition. I bought my first propo gear (Swan) and fitted that along with an OS 30. Mine had been built as rudder/elevator/ motor but flew great anyway until about 1979 up at the Walsall site (Greenacres), using 27mhz when someone whose name I forgot switched on to my frequency and brought me down. (Apologies were appreciated but not much compensation). Damage wasn't great so I put it away for another day and still haven't got around to it. Clearly I must, it would be great to see a few of these around again. However, the subject of this thread obviously isn't a Jackdaw after all, but it's been nice to talk about it.

PatMc Posted November 14, 2013 Share Posted November 14, 2013 Tyro Too was just a tarted up 45" Tyro, IIRC it had a swept fin & might have had optional ailerons. Quote Link to comment Share on other sites More sharing options...
