jeff2wings Posted December 28, 2022 Share Posted December 28, 2022 (edited) So this was started a few years ago for one of the mass builds but was put aside as a result of 'barnstormer fatigue' after building the 63 & 72 inch versions,this being the original 52" single channel one (when DB was button man) Edited December 28, 2022 by jeff2wings More pictures Quote Link to comment Share on other sites More sharing options...
GrumpyGnome Posted December 28, 2022 Share Posted December 28, 2022 I've long hankered after a Barnstormer, but other things keep getting in the way. Watching with interest. Quote Link to comment Share on other sites More sharing options...
jeff2wings Posted December 28, 2022 Author Share Posted December 28, 2022 Well they come in various sizes from 32" to 90" and would be a easy conversion to EP ,when I made fuselage for the 63" one it was without the extra 'padding ' that DB added on the following versions. I have made a few changes to the way the wing is made and of course to the tailplane but that's all. Quote Link to comment Share on other sites More sharing options...
kc Posted December 29, 2022 Share Posted December 29, 2022 (edited) It is worth saying that Boddington updated the Barnstormer 63 and called it Mark One - the plan is on Outerzone together with the 52 inch, the 39 inch Baby, the 29 inch Micro and 89 inch Mighty Barnstormer. Boddo didn't do a 58 inch Barnstormer but if you scale up a 52 inch plan to 110 percent then a set of Tyro Major wing ribs just suit. DB Sport & Scale sell the wing rib sets for Tyro Major and also the 63, 72 and 88 inch Barnstormer plan & ribs etc. Edited December 29, 2022 by kc Quote Link to comment Share on other sites More sharing options...
jeff2wings Posted December 30, 2022 Author Share Posted December 30, 2022 Well apart from joining the wing panels and a good sanding down the construction is done just need to dig out a few suitable engines and then decide on what type of covering to use? changes to wing panel construction was to leave out the rear spar,add extra vertical webbing Tailplane now a standard flat plate like the later versions but without spars top and bottom ,l never really liked that No problem going EP with this if you want, I will be using the engine mounting plate as designed so it will be easy to swap different engines to try out carving that top decking was fun if a bit messy lol !

Christopher Wolfe Posted December 30, 2022 Share Posted December 30, 2022 The Barnstormer is a lovely classic design but why do aeromodellers insist on shaping a solid slab of balsa for the moving control surfaces (typically rudder/elevator/ailerons) when even in the 1930's and 40's high performance metal skinned aircraft utilised fabric covered control surfaces? Not an aeronautical engineer but pretty sure that the exerts did their sums back then. To my thinking, this is just adding weight where it is not needed 🙃 Quote Link to comment Share on other sites More sharing options...
jeff2wings Posted December 30, 2022 Author Share Posted December 30, 2022 Because that's how DB designed it ? 1 Quote Link to comment Share on other sites More sharing options...
kc Posted December 30, 2022 Share Posted December 30, 2022 So the tailplane is no longer an airfoil section " as DB designed it"? In fact solid balsa tailplanes can often be much the same weight as a built up one - if one can choose a nice bit of light balsa. Quote Link to comment Share on other sites More sharing options...
jeff2wings Posted December 30, 2022 Author Share Posted December 30, 2022 One of the advantages of building from plans, as I'm sure you're aware kc,you can make changes to suit your own preferences what ever they may be,in this instance I left out the rear spar as it seems unnecessary and the 'aerofoil ' of the tailplane (that's more of a diamond profile) again because I see no advantage over a flat plate for this type and size of model.

kc Posted December 30, 2022 Share Posted December 30, 2022 As originally designed the Barnstormer 52 did not have an elevator, so changing the construction when adding an elevator seems worthwhile. Its interesting that the 52 tailplane is quite wide - spans 21 inches I think - while the 63 is 24 inches which is not quite scaled up in proportion. Wide tailplanes make the model unwieldy in transportation and storage! I recently acquired a nicely built electric Barnstormer 63 ( ex everybody at my club! ) and I wonder whether you have any comments on where the CG should be for that size ( with lifting section to tailplane ) As I don't have the plan for that size I don't know what Boddo specified, so I will try 25 percent to start with and maybe work back a little after a test flight. So any comments on what you found worked well would be welcome. Quote Link to comment Share on other sites More sharing options...
jeff2wings Posted December 30, 2022 Author Share Posted December 30, 2022 Just found the (tatty!) plan and it shows cg on the main spar ,if you have excessive climb under power add spacers to the rear struts to lower the AoA on the wing Quote Link to comment Share on other sites More sharing options...
jeff2wings Posted January 1, 2023 Author Share Posted January 1, 2023 So a bit more progress with the barnstormer............... ply wing bracing going in Os max 15 lll fitted with 1/8 " tufnol ? plate that will make changing engines a simple affair alternative engines are Enya 15,os 19,Enya 19 ,HP 20 etc Quote Link to comment Share on other sites More sharing options...

jeff2wings Posted January 9, 2023 Author Share Posted January 9, 2023 So the barnstormer is finished 👍apart from final fitting out,I won't bother documenting it, all standard stuff. Onto the next unfinished project! 4 Quote Link to comment Share on other sites More sharing options...
