David perry 1 Posted February 26 Share Posted February 26 (edited) I bought a kit some time back, The Answer from Cambrian models. Has anyone built a Cambrian Models The Answer? Looks pretty enough, possibly a contender for my PAW1.49. David Edited February 26 by David perry 1 Quote Link to comment Share on other sites More sharing options...
David P Williams Posted February 26 Share Posted February 26 Tried to build one, fuselage and tail OK, wing not so good. You’re supposed to glue the wing outline components together then soak and pin down over the supplied camber jigs. Unfortunately the “balsa” that the supplied wing frame components were cut from was more like oak, and the glue I used was not waterproof enough, so I gave up in frustration and eventually lost interest and sold it.

David perry 1 Posted February 26 Author Share Posted February 26 Thanks for that. Yes I read those notes and at first I wondered if it was a Jedelsky wing but it seems not, it’s something else. Any versions I’ve seen on the yoochoob videos all show conventional built up wings, so maybe everyone gets fed up. Maybe life’s too short to mess around fixing Cambrian’s oddities and I ought to find another pretty vintage build. Maybe an Elf Bipe Aanyway thanks Quote Link to comment Share on other sites More sharing options...
Jonathan Posted February 26 Share Posted February 26 (edited) I purchased one last summer, haven't started the build yet. Does look a lovely plane. Edited February 26 by Jonathan Quote Link to comment Share on other sites More sharing options...
Engine Doctor Posted February 26 Share Posted February 26 (edited) I built one a few years back . Covered it in Fibre Span ( Horrible stuff ) Light span would be much better. Power was an OS 10 or 15 and was a bit OTT and heavy . It flew fine but fast due to the heavy engine. Your 1.49 will fly it ok but like mine may be a bit too heavy for a slower gentle flight. Wing is a simple build but with a fair bit of under camber and the hardest part was fixing the covering to the under cambered part. The Elf Bipe is a pretty model, mine is a Ben Buckle 60 inch version with OS 40 FS power with wings built from the Outer Zone plan as I had what I thought was akit but wing parts except ribs and plan were missing. Dont know if there is a original sized 36" kit around . Edited February 26 by Engine Doctor 1 1 Quote Link to comment Share on other sites More sharing options...
Nigel Dell Posted February 26 Share Posted February 26 I think you will find that the Cambrian the Answer kit is true to the 1940’s design for the wings I have the original plan somewhere. 2 Quote Link to comment Share on other sites More sharing options...
Tim Hooper Posted February 26 Share Posted February 26 (edited) Don't listen to the nay-sayers. I built my Cambrian Answer from the kit around a decade ago, and it still remains one of my favourite models, and is a regular flier for calm conditions! Your PAW 1.49 will probably be too much at full power for such a light airframe - although the noseweight might be useful. (Mine is electric, and uses a little outrunner on a 2S 1300 lipo, turning a 9x6 slo-fly prop). Yes, the Ritz wing design is unusual in its construction, but perfectly feasible to build and works well in flight. Mine is covered in tissue-over-Doculam. The bright yellow and red schem has faded considerably over the years, and is now a subtle lemon/pink combination. Tim Soaking the wing panels Joining the wing Planning the motor and battery as far forwards as possible. The naked airframe Red and yellow tissue over Doculam An old cylinder head has fooled quite a few! It's a lovely flier - honest!

Tim Hooper Posted February 26 Share Posted February 26 (edited) Whilst I'm on the subject....... I was so impressed with the Cambrian Answer that when I stumbled on a 50" variant on the OuterZone plans site, it was a no=brainer to build another! 50" Answer plan Very similar to the smaller 44" original, but this one sports an Indian Mills 1.3 diesel - just perfect for relaxed pottering. Because there are no hardwood strips in the wing panels, they've pulled into a pleasing elliptical dihedral as the covering tightened.

David perry 1 Posted February 26 Author Share Posted February 26 I’m not sure how to print a tiled plan from outer one as I use a Mac laptop. Do I still use adobe or something else? Quote Link to comment Share on other sites More sharing options...

Tim This reminds me of a vintage model I’m sure I read about years ago where the wing build called for it to me made, or part made maybe, then supported by the tips between two chairs and left with a 1 or 2lb weight tied to the centre. It gave it a beautiful curve over a few days. I’ve always fancied trying it but never have. Quote Link to comment Share on other sites More sharing options...

David perry 1 Posted March 4 Author Share Posted March 4 Two panels done. Amazingly with the same curve ha ha. It works. 3 1 Quote Link to comment Share on other sites More sharing options...
David perry 1 Posted March 8 Author Share Posted March 8 Wings joined and shaped. Next to cover them. Options are doculam then tissue or nylon. Silk would be perfect but I don’t have it whereas I do have nylon. Shrinking dope to try to get the alleged curving effect. I must say it’s a beautiful wing when it’s made. 1 Quote Link to comment Share on other sites More sharing options...
David perry 1 Posted March 11 Author Share Posted March 11 Basic fuselage sides built. I hadn’t appreciated the shape of the thing. Quite wonderful. 1 Quote Link to comment Share on other sites More sharing options...

Tim Hooper Posted March 14 Share Posted March 14 Looking good! To save weight at the rear end I binned the supplied snakes, and went for a lighter weight pull-pull set up for the rudder and a skinny carbon fibre pushrod for the elevator. I think the Answer was the forerunner to the Scorpion and Super Scorpion - although they both had a 'conventional' aerofoil section and structure.

David perry 1 Posted March 14 Author Share Posted March 14 Thanks Tim ive ordered snakes and some smaller-than-standard servos. It’s a bit tight in there for my fingers. Quote Link to comment Share on other sites More sharing options...
David perry 1 Posted Saturday at 09:28 Author Share Posted Saturday at 09:28 (edited) Radio fitted (etronix 17g) cowl blocks added pre carving and PAW149 fitted to check spaces. It’s coming along now I have no idea where to fit the fuel tank yet. Edited Saturday at 09:29 by David perry 1 2 Quote Link to comment Share on other sites More sharing options...
David perry 1 Posted 13 hours ago Author Share Posted 13 hours ago Here we go. pretty much ready to cover. Still perplexed about the tank ha ha. I need a 1 oz or a metal home made one. Anyway the airframe is done. The PAW looks ok in fact. Just need fuel! 1 Quote Link to comment Share on other sites More sharing options...
