Edgeflyer Posted September 6, 2024 Share Posted September 6, 2024 I came across this nice little trainer and I have the wing plan and a rib template from a late modeller. I'd like to build one with an OS10 up front. Does anyone have a plan for the fuselage? Quote Link to comment Share on other sites More sharing options...
Robin Colbourne Posted September 6, 2024 Share Posted September 6, 2024 Ben Buckle do. Sid King Novice Plan. Quote Link to comment Share on other sites More sharing options...
Edgeflyer Posted September 7, 2024 Author Share Posted September 7, 2024 Thanks for the link. Yes I've seen that one and their rather indistinct picture looks like it's been changed to all sheet tail etc. Has anyone built this model?

John Wagg Posted September 7, 2024 Share Posted September 7, 2024 Not built this but you could draw up your own plan. Use the rib length to work out the comparative fuselage dimensions. Or, with the BB plan, you can always make a built up tail. I did my own similar many years ago (1990) and still going strong. Originally with a clapped out Enya.15, although now with a clapped out OS.20. From 40 seconds. Quote Link to comment Share on other sites More sharing options...
Edgeflyer Posted September 7, 2024 Author Share Posted September 7, 2024 Ok that's interesting. What is the relationship between rib length and fuselage length? Quote Link to comment Share on other sites More sharing options...
kc Posted September 7, 2024 Share Posted September 7, 2024 you could measure from the photo or in this case off the photo on the computer screen and it seems to be 1.9 times the wing chord to the fin/ rudder joint or 1.4 times chord to the tailplane LE at fuselage. I excluded the wing tip protrusion or winglet from my calculation . Quote Link to comment Share on other sites More sharing options...
kc Posted September 7, 2024 Share Posted September 7, 2024 Frankly it's not really worth drawing up your own plan as the plan only seem to be about £6. plus postage. If your home drawn plan is not quite right and you waste a couple of sheets of balsa it's dearer! Much quicker to build from a ready made plan than work out the unknown details.

kc Posted September 7, 2024 Share Posted September 7, 2024 Looking again at the Ben Buckle small plan which is 50 inch span for glow, it may be a quite different model to the one in your photo which seems to be the Sarik electric plan version with only 40 inch span with a somewhat shorter fuselage proportion. Ben Buckle plan seems 2.3 times chord to rudder line ( not 1.9 times ) so the rib template might be for one plan but not the same as the other version.

Edgeflyer Posted September 7, 2024 Author Share Posted September 7, 2024 Oh thanks. The photo was just one I found at random. Pretty sure my plan is the 50 inch for OS 10 glow. I'll check Quote Link to comment Share on other sites More sharing options...
