Henry Posted January 19, 2015 Share Posted January 19, 2015 Hi guys I thought I would post the progress on my tyro major I've been building for a few months. It's my first build so any constructive comments are welcome! I acquired a print out of tatty looking original db tyro 54" plans and thought it would make a good little project. It has been a bit of a learning curve And I've enjoyed building it a lot . Here's some piccys Quote Link to comment Share on other sites More sharing options...
bert baker Posted January 19, 2015 Share Posted January 19, 2015 Nice model to build. Tissue and dope it in different colors, its good fun and dope is fuel proof Andrew Boddington vid on YouTube is worth a look at Just remembered you are doing the Major Edited By bert baker on 19/01/2015 23:18:56 Edited By bert baker on 19/01/2015 23:20:13 Quote Link to comment Share on other sites More sharing options...
jrman Posted January 19, 2015 Share Posted January 19, 2015 None of the dope (butyrate or nitrate) that I have ever used has been glow fuelproof. Quote Link to comment Share on other sites More sharing options...
bert baker Posted January 19, 2015 Share Posted January 19, 2015 Sorry I was thinking of the Min Tyro with a diesel engine. Quote Link to comment Share on other sites More sharing options...
John Privett Posted January 20, 2015 Share Posted January 20, 2015 The Tyro Major was my first R/C model, a little over 40 years ago now... That was built from the plan too - I'd done a fair bit of control-line flying before that. Nylon-covered and powered by an Enya 19, it survived my best attempts to kill it whilst I learnt to fly, and was passed on to another beginner. Looking forward to seeing Henry's pics!

Jimbo565 Posted January 20, 2015 Share Posted January 20, 2015 Like John,the first model I ever built, covered in Solarfilm and os20 up front, so long ago I cant remember. Quote Link to comment Share on other sites More sharing options...
Chris Bott - Moderator Posted January 20, 2015 Share Posted January 20, 2015 Looking forward to this, always had a soft spot for the Tyro. Quote Link to comment Share on other sites More sharing options...
kc Posted January 20, 2015 Share Posted January 20, 2015 You can buy a set of wing ribs for the Tyro Major for 7.50 pounds from DB Sport & Scale. They are beautifully laser cut. Got to be worth buying. A plan is available for 10 pounds from DB for those who need it. Check out DB's other Plan Packs for other models at reasonable prices.

Keith Evans 3 Posted January 20, 2015 Share Posted January 20, 2015 When I came back to the hobby about 10 yrs. ago this is what I built .however I could not cope with a tail dragger then , as I was teaching myself. Too much elevator with dire results .My fault and inexperience , nothing wrong with the design so I opted for the trike version .I was so naïve that I controlled the rudder with the rudder stick on the tx. not the aileron stick.I eventually found that as a primary control I should allocate the rudder to the aileron stick for a three channel plane .It did me no harm and on an occasion when I lost aileron control on another model I was fully at ease bringing it home using the rudder . Don't try fast multiple loops with it though ,the wing can't take it ,don't ask how I know! ! In total I built three of them . It was powered by a thunder tiger 25 .and covered in Solarfilm . Best of luck you'll enjoy it . Quote Link to comment Share on other sites More sharing options...

Henry Posted January 20, 2015 Author Share Posted January 20, 2015 wings are angled properly and balanced, i have got 1 more piece to cover and then i will look at tuning the engine and setting up radio gear kc. i bought those they were brilliant, the man from db was very help full! saved me lots of time! keith cheers for the heads up! i have got 2 different engines i could stick in here 1 is an os max 35 fp? and the other i will have to dig out at the weekend and look at the name, what do people make of the os max 35? i have heard mixed reviews?!?

Chris Bott - Moderator Posted January 20, 2015 Share Posted January 20, 2015 Henry I hope you don't mind me experimenting with your photobucket link. I'll delete this post if it doesn't turn out how I expect. OK it seems we can click on the arrows on the sides of the picture, OR click a picture and see just that one.

Henry Posted January 20, 2015 Author Share Posted January 20, 2015 Wow how did you do that i was trying to figure it out for ages! Quote Link to comment Share on other sites More sharing options...
Chris Bott - Moderator Posted January 20, 2015 Share Posted January 20, 2015 Well it's the first time I've tried it with Photobucket. But following your link I went to the Photobucket album. On that page there's a section at the right headed "Share Links", I clicked on the "Story Embed" one, whereupon it said "copied" Next I came here, clicked on the button obove the posting box next to the youtube one (it's called Embed Media when you hover over it). In the box that appeared I pasted what had been copied from photobucket. (To paste, "Right click" in the box and then click "Paste". Quote Link to comment Share on other sites More sharing options...

David Davis Posted January 21, 2015 Share Posted January 21, 2015 OS Max 35 FP? Fine engine! Not a ball of fire but well-made and reliable,smooth and very quiet, ideal for a trainer like this. I have the 40 -sized version. Quote Link to comment Share on other sites More sharing options...
Dai Fledermaus Posted January 21, 2015 Share Posted January 21, 2015 Hello Henry, I don't want to appear a smarty pants, and I hate it when people do this to me after the event, but I thought I'd say that the build instructions are still available from DB Sport and Scale which recommends that the fuselage sides are built as in the photo below. The Major is a tough as old boots though, so I'm sure yours will be fine Quote Link to comment Share on other sites More sharing options...
kc Posted January 21, 2015 Share Posted January 21, 2015 It is normal to build the square reinforcements onto the side sheets as the photo shows.and this applies to all other models with similar sheet sided construction. It's much easier and probably a bit stronger as every component is glued firmly to the sheet sides and only bent into the tail when complete and glue is dry. The OS 40 FP is not a powerful high revving motor but it will turn a large prop. If you look at engine tests when it was first made the results on an 11 x7 were almost the same revs as a 10 x6. So an 11 x 7 is the right prop to use ( dont believe the 'experts' who say you must use a 10 x6 ) Probably similar with the OS35FP so maybe an 11 x 6 would be a good prop.

Henry Posted January 21, 2015 Author Share Posted January 21, 2015 Hi dai and kc. I found that picky on the net after I started building it, next time I will do it like that, it all seems to be in line and all so hopefully it will be ok, if it's anything like the other planes I've had it probably won't last long and I will have to rebuild it Cheers kc the prop was 1 of the things I was going 2 ask about! The other thing I was going to ask is on the plans the engine mounting plate is cut so the engine is mounted at a angle, I purchased a part from db for this, it's cut out of some synthetic wood stuff but the part where the engine goes isn't cut out,do you know the reason for this angle ? Cheers guys! Quote Link to comment Share on other sites More sharing options...
Keith Evans 3 Posted January 21, 2015 Share Posted January 21, 2015 It's so the engine will point one to two degrees to the right to counteract the spiralling wash from the propeller hitting the fin and therefore trying to push the plane to the left .
