The covering film is from Hobby King, which whilst selected on cost grounds I am very pleased with; pity their stocks are so low which limited colour choice.

jeff2wings Posted December 15, 2013 Share Posted December 15, 2013 Posted by Dave Miller on 15/12/2013 13:02:40: I’ve finally got around to assembling the beast and running the engine on load for the first time. With a JXF 17x10 propeller I got 7,150 rpm, I have no idea if that’s good or not but it did seem to be sucking quite well. Now all I need is a warmish dry day for the maiden flight. That's more or less the same rpm I get from my ST 2500 on a APC 17x10 ! looks realy great btw Quote Link to comment Share on other sites More sharing options...

Phil Winks Posted December 15, 2013 Share Posted December 15, 2013 That looks superb Dave wouldn't have thought the more modern colour scheme would suit her but it does very well, with xmas coming in at a gallop I should get time to start mine real soon, and after your success with that bright scheme I may be re-thinking mine, perhaps I should follow my theme from last years build in blue and yellow ??

Dave Miller Posted December 15, 2013 Share Posted December 15, 2013 Thank you. I'm sure yellow and blue will work very well Phil, the brighter the better. Quote Link to comment Share on other sites More sharing options...

Nigel Day Posted December 21, 2013 Share Posted December 21, 2013 Looks great Dave and thanks for all the info you've posted. I'm starting a 63" in the New year so it'll all be very useful. Quote Link to comment Share on other sites More sharing options...

I was wondering how much dihedral you have gone for? Hope you don't mind the questions? Quote Link to comment Share on other sites More sharing options...
Dave Miller Posted December 21, 2013 Share Posted December 21, 2013 One inch under the outboard rib of each wing with the centre section flat on my building board just to stop the droopy look that a flat wind would have given; and no, I don't mind your questions that's what forums like this are for.

kc Posted December 30, 2013 Share Posted December 30, 2013 I have not got the 63 plan yet, so can anyone tell me the chord of the 63 inch wing please?Reason I want to check this is because I already have a set of DB 'Richtofen' ribs which I suspect are identical to the Barnstormer. It would be interesting also to know the maximum depth of the Barnstormer ribs including sheeting.Thanks. Quote Link to comment Share on other sites More sharing options...
Nigel Day Posted December 30, 2013 Share Posted December 30, 2013 Hi KC. My ribs are 36mm deep(max) by 23.8cm long. According to the plan, the wing depth (chord?) is 25.5cm. I hope that helps. Quote Link to comment Share on other sites More sharing options...
kc Posted December 30, 2013 Share Posted December 30, 2013 Thanks Nigel, they are not quite the same then. The Richtofen is 248 mm chord which includes a 1/2 inch leading edge ( say 13 mm)so the actual ribs are 235mm which is close enough to your 238mm. The depth of Richtofen ribs is 31mm but that has no wing sheeting.so with 1.5mm sheeting top & bottom it would be 34mm -- a bit different but not significant on a parasol wing.If your plan does not quite match the actual ribs it may be because of a photocopy or blueprint stretching a bit in one dimension. I always run a ruler over any plan to ensure all the bits match. Often they vary a few millimetres, so it helps to know this before construction starts so any errors can be allowed for.I assume the Barnstormer has a huge chunk of balsa for the leading edge like the 1/2 inch by 3/4 inch shown for the Richtofen. I would always make the wing with a 'false' leading edge of 1/8 inch and cover this with the 1/16 inch sheeting overlapping the 1/8 by a fraction. After the glue has dried then sand the sheeting back flush to the false leading edge. Then a thicker LE is glued on front. To save too much shaping this can be several layers each a little narrower to get close to the eventual shape. Saves a lot of balsa and a lot of dust or shavings!I hope anyone can understand my description - if not I will draw a diagram. Quote Link to comment Share on other sites More sharing options...
Nigel Day Posted January 1, 2014 Share Posted January 1, 2014 The leading edge is 1" x 1/2" according to the plan. Almost enough to make another model from the shavings! Quote Link to comment Share on other sites More sharing options...
Dave Miller Posted January 1, 2014 Share Posted January 1, 2014 I made mine from two layers of 6mm, the first with the front sheeting over lapping after it was shaped and the front one added after the sheeting. Quote Link to comment Share on other sites More sharing options...

jolliffee Posted January 4, 2014 Share Posted January 4, 2014 I was just admiring the look and thought the colour scheme made it look very modern - I do like the spats they are the perfect extra. Quote Link to comment Share on other sites More sharing options...

Dave Bran Posted January 5, 2014 Share Posted January 5, 2014 Yes, Very Nice, Jeff. Spats look very good, but I'm not so sure about the red/orange trim, will it be used elsewhere, too? Stuck at home with a flu bug, and temporarily clear of Heli building, I have finally got back to mine and cut the other Aileron out, fixed hinge supports, servo mounts, and made a path through the wing for the wiring back to the cabane struts. I want the stud and nut fixed wing and the tail to be quick removal, so wiring has to be separable at the struts. Not sure yet how to best support and disguise it. I'm still working on the complete tail being nut and studding fitted too, so easily removable, not so much for transportation but for storage, a 72" Barnstormer has a LARGE space grabbing tailplane!!! I already have a wide wire undercart with nice large wheels, but may sheet it in and add spats (if I can find some large enough units, as no time or skills to make!). It will probably look better with cosmetic outboard struts, but will I have the time or interest?? Watch this space (or should I say void!). Probably will install magnets in wing before covering in case I want to add Another thing is that the Fus came to me with a fixed tailwheel........ It is REALLY well fitted, and altering it is not a simple task, but my thinking is a steerable would be better..........Thoughts?? Quote Link to comment Share on other sites More sharing options...
Dave Miller Posted January 5, 2014 Share Posted January 5, 2014 I add my complements Jeff, you have produced a very tidy model. Dave, I think that the ground handling will be awful without a steerable tail wheel; it's well worth making the alteration if you can. I'm now making a pair of floats for mine, just in case we have a wet summer. Quote Link to comment Share on other sites More sharing options...
