john stones 1 - Moderator Posted January 2, 2015 Share Posted January 2, 2015 It's looking very good Dylan should be quite impressive at this size. Have you considered adding a ply laminate where the rear fuzz longerons join the balsa cabin ? Been a few breakages at this point (pilot induced...me) at this size the added weight would be no big deal ? John Quote Link to comment Share on other sites More sharing options...
Dylan Reynolds LaserCraft Services Posted January 2, 2015 Author Share Posted January 2, 2015 Thank you John, but it's not finished yet I have looked at that idea, and still mulling it over, there are actually a couple of areas that need extra strength to the original one when you get to this size, actually considering rebuilding the fuz again but with those top longerons running full length to the front of the fuz, maybe, maybe not, might carry on, test fly this one and rethink if things fall off Quote Link to comment Share on other sites More sharing options...
Phil Winks Posted January 2, 2015 Share Posted January 2, 2015 John is spot on on that weak spot mine hasn't even flown yet and a minor drop oo to the tail skid from 45 degrees(wheels on the floor) caused that balsa triangle to start to split the idea of running the longerons right through to the front of the main wing looks a way to go Edited By Phil Winks on 02/01/2015 19:25:36 Quote Link to comment Share on other sites More sharing options...

Lindsay Todd Posted January 3, 2015 Share Posted January 3, 2015 Impressive Dylan, I would take the opportunity to beef up a few points at this size, some extra triangulation or rigging on the tail might be a good idea, can't wait to see it finished.

Dylan Reynolds LaserCraft Services Posted January 3, 2015 Author Share Posted January 3, 2015 Yes the tail end has given me a bit of concern and I will probably scrap the first one and rebuild with a stronger design. I will be going for full rigging on the wings and the tail, I am also look at doing a pull/pull for the elevators as well as the the rudder. 1.5mm sheeting on the outer fuz will also be applied to strengthen up the weak point, and the rest I'll make up as I go Quote Link to comment Share on other sites More sharing options...

reg shaw Posted January 3, 2015 Share Posted January 3, 2015 What span are we talking here!!?? Just be careful of too much beefuppery or you'll end up with a model that has to fly too darned quick for its style. I'd use the original tailplane but fit cable bracing and it will still look like a Dawn Flyer. Obviously the above is just my opinion, there may be others!! Ian.

Dylan Reynolds LaserCraft Services Posted January 3, 2015 Author Share Posted January 3, 2015 96" Ian and I'm inclined to agree, I don't really want to over engineer and redesign the thing, otherwise it won't be a Dawn Flyer, but there are some areas that need attention at this size, but who knows big toys better than most around here? (I know it ain't me). Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted January 3, 2015 Share Posted January 3, 2015 Now I feel guilty I had no intention of knocking Lyndsay's design nor Dylans ability to build it, just a minor mod suggested. John P.S don't forget you'll need a bigger scarf Quote Link to comment Share on other sites More sharing options...

Dylan Reynolds LaserCraft Services Posted January 3, 2015 Author Share Posted January 3, 2015 Re reading my post, I don't think I quite worded it how I intended, I am just a tad frustrated at the mo, because I have spent 8 hours sorting a retract linkage on a so called artf, my own fault for putting down the DF and thinking I could get the chinese wonder done in a day ah well. No, indeed there is no need to feel guilty at all, all suggestions are welcome, I was leaning toward Ians idea anyway really at the back of my mind after spending umpteen amounts of hours messing with WW1 stuff and knowing how they throw together, Ian has sort of reassured my thoughts, and as I say, he knows his big toy stuff I am still thinking of a few strengtheners in the tailplane, but nothing over major as I want to keep it light. The scarf is on order John Quote Link to comment Share on other sites More sharing options...

Lindsay Todd Posted January 3, 2015 Share Posted January 3, 2015 John, no guilt required all good stuff on here. All contributions welcome I'm sure and have no doubt Dylan will make a cracking job in the end. Might have to do a bigger one though at some time, I have a Zenoah G62 lying around.

Chris Barlow Posted January 3, 2015 Share Posted January 3, 2015 Nice work there Dylan. Looking at the photos last night (or rather early this morning) made me want to get my DF out again. Unfortunately our field is like a bog at the moment and I wouldn't like to have to clean all the mud out of the rear framework! I would think that even with a little strengthening it's still going to be a nice slow floater. Quote Link to comment Share on other sites More sharing options...
Dylan Reynolds LaserCraft Services Posted May 1, 2015 Author Share Posted May 1, 2015 WOW! has it really been that long since I did anything to her? well here's a quite update to where we are with it (amazing what you can get done in a week off lol) I didn't like the 2" ali tape I used on the front end to simulate an ali cowl so I stripped it and built a "proper" one, this is my first attempt at ali litho plate work (I'm just gonna post the pics and not go into too much detail unless anyone has specific questions) First some templates Then cut the litho plate Then add a little detail in the way of rivets Then a bit of bending and gluing sees it fall into place Quote Link to comment Share on other sites More sharing options...
Dylan Reynolds LaserCraft Services Posted May 1, 2015 Author Share Posted May 1, 2015 Then I got the tail feathers covered and fitted (actually I did this before I did the cowl, but don't tell anyone ) I decided to beef up the bottom section and also ply laminate the sides for extra strength Then a bit of staining and bobs your mothers brother Quote Link to comment Share on other sites More sharing options...
