It is currently in bits on a shelf, after a nasty tipstall incident. According to his website, the Tony Nijhuis 72in Mosquito weighs 14lbs and has a wing loading of 40oz/squ ft. Tapered wings and a high wing loading is not a combination made in heaven. ☠️ Quote Link to comment Share on other sites More sharing options...

It would be better about 60" with a single battery. I tend to fly the 110 more as it is one piece, twice as many flights with the same batteries and I can hand launch it myself. Now I have the dolly I will see how the Mosquito goes from that. 5 Quote Link to comment Share on other sites More sharing options...

The lower wing sheet is Hobbycraft foamboard and the top sheet is Maker foam board as it is easier to form. 1 Quote Link to comment Share on other sites More sharing options...

I think the 60-odd inch size that Eric is talking about would be the sweet spot for me, for a Mossie. So much so that I managed to resist a 73" span CMPro one that went to auction on eBay at the weekend and went for a song. Didn't look half as nice as Eric's one there though - the CMPro one has quite a portly fuselage and there is something about the nacelles too. 1 Quote Link to comment Share on other sites More sharing options...

Just looked up the CMPro Mosquito on YouTube and it looks too short making the fuselage look porky, the nacelles look oversize probably to accommodate the motors fuel tank and retracts. Mine are wrong too the front lower cowls are Spitfire. Quote Link to comment Share on other sites More sharing options...

Eric Robson Posted April 24 Share Posted April 24 There is a 96"span Dc3 balsa build on the forum. Robin Fowler design, the specification is just over 9 lb two 3s 4000 batteries , inexpensive small motors. And it's fitted with retracts. It can be done.

GrumpyGnome Posted April 24 Share Posted April 24 I suspect it's not very....... robust Quote Link to comment Share on other sites More sharing options...
Andy Gates Posted April 24 Share Posted April 24 (edited) GG If you build light, then you do not need to fly so fast so the energy taken into any mishap is very much reduced allowing for a less beefy construction. KE = 1/2 m v2 (2 is squared - I could not find the superscript function) My Mossie which is now 17 years old and still flies regularly. 74" wingspan and weighed around 5lbs including batteries, (2 x 3S 2800mAH). As Richard would say, more "cartoon scale" but great fun and shows no sign of tip stalling.

GrumpyGnome Posted April 24 Share Posted April 24 I understand that but the DC3 in question is significantly bigger, and the thread mentions fatigue in the fuselage area - from general use I believe. I expect my models be flyable 12 months a year, and not have to leave them at home if the ground is too hard, too soft, or has too many worm casts. So I like a little robustness 🙂 1 Quote Link to comment Share on other sites More sharing options...
Eric Robson Posted April 24 Share Posted April 24 (edited) Hi, GG, The stress cracks mentioned were regarding a Percival Prentis by the same designer caused by a heavy landing. The method of separating the fuselage is not the way I would be happy with as it is at a point where a 3 point heavy landing would create a lot of stress but Robin Fowler favours it and it seems to work for him. Early Fw Condors were prone to go at that point. Edited April 24 by Eric Robson Added text Quote Link to comment Share on other sites More sharing options...

So I got to fly some of his models including the Mossie and his very light Chipmunk . The designs are by Ivan Pettigrew and are a bit like the old kiel Kraft stringers and tissue style of construction . Probably a bit too semi scale as Andy says , but amazingly easy to fly when you compare it with the more typical 14lb 72" Mossie . You certainly felt comfortable flying it with every confidence of bringing it home in pristine condition . Going a little more scale will be the answer . But it shows what can be done . The landing speeds were trainer like , so quite modest retracts would suffice . Have a look at his plan as his method of undercarriage was unusual but clever . Thanks Andy . 2 Quote Link to comment Share on other sites More sharing options...

andrew exton Posted May 1 Share Posted May 1 well just radio gear to sort ,sorry no pilot yer not found one & haven't got the luxury of a 3d printer , looking forward to flying her & hope she flies as well as every one else's andy 11 Quote Link to comment Share on other sites More sharing options...
RICHARD WILLS Posted May 1 Author Share Posted May 1 Very Nice Andy . The Mediterranean colours show of its clean lines . I thought that about the captured 109 "black 6" when I first saw it . That colour is really easy to see in all weathers too . great job 😁 Quote Link to comment Share on other sites More sharing options...
John Timmis Posted May 2 Share Posted May 2 Hi, here is another one ready to go. I wanted to try Richard’s monochrome finish, I think it has worked well. It has a Quantum 40 motor, about 700 watts on a 12 x 6 prop & 4s 4000 lipo. The cg is at 85 mm. Is that OK? Can you remind me of what the control deflections should be please? I have really enjoyed this build & following the numerous threads, can’t wait to start on the Tempest. John. 3 Quote Link to comment Share on other sites More sharing options...
RICHARD WILLS Posted May 2 Author Share Posted May 2 Blimey John , that is so like mine I could take it home by mistake! Have you considered counterfeit notes ? The only way I'd know which one to take home is that mine is the right way up 😁 Joking aside , I think this proves beyond doubt that if you follow a simple process in bite size chunks, you will end up with an outstanding result , easily able to challenge the best ARTFs plus have the satisfaction of saying that you properly built that (as apposed to an assembly ) . John , if you are wondering what your plane looks like the other way up , it a lot like this . Thanks for your comments , makes it all worthwhile . 2 2 Quote Link to comment Share on other sites More sharing options...

You must have the CG spot on as it’s so stable inverted! 1 Quote Link to comment Share on other sites More sharing options...
