Martyn K Posted July 30, 2014 Share Posted July 30, 2014 Just remember - for it to be a true scale model, it needs unreliable engines. I wonder how many will replicate that 'feature'? Martyn Quote Link to comment Share on other sites More sharing options...

Dylan Reynolds LaserCraft Services Posted July 30, 2014 Author Share Posted July 30, 2014 OK a 2nd show of interest in a 1/4 scaler, right, when I have moved house (friday) and set up the workshop again I will sit down and produce some smaller and bigger versions of this one. The same thing is happening with the Mozzie, I started at 81" the same as Brian Taylors, and scaling one up to 106" 1/6th scale, now I have also had requests for a 120" and a 1/4 scale for that Quote Link to comment Share on other sites More sharing options...
A.A. Barry Posted July 30, 2014 Share Posted July 30, 2014 I look forward to the results Barry Quote Link to comment Share on other sites More sharing options...
David Pearce 4 Posted July 30, 2014 Share Posted July 30, 2014 I would love to see a smaller electric version. Big enough for retracts (including tail wheel) but not so big that it needs anything larger than a pair of 4S lipos. Such an iconic airplane deserves to be represented in the RC world!

Kelly Posted July 30, 2014 Share Posted July 30, 2014 For those of us without bottomless pockets or time for building a smaller foamy would be quite nice . I am tempted by this one as a long term build project ,very nice looking kit Quote Link to comment Share on other sites More sharing options...

David Pearce 4 Posted August 1, 2014 Share Posted August 1, 2014 Hi Dylan Looking at the Whirlwinds rather short nose, do see any problems in getting the C of G right, especially in any electric versions? The fuselage is rather narrow and I was wondering how far forward you can get the lipos. Cheers David Quote Link to comment Share on other sites More sharing options...

Jon H Posted August 1, 2014 Share Posted August 1, 2014 It looks fantastic, I might have to start clearing my build bench. Is she a perfect 5th scale? Quote Link to comment Share on other sites More sharing options...
Colin Leighfield Posted August 1, 2014 Share Posted August 1, 2014 David's comment about the cg is worth considering. My 70" Welkin is proportionally very similar to its' Whirlwind smaller brother and with the short nose it's proved difficult to get the cg right. The answer is to use two Lipos and put one in each nacelle, well forward. That's on my list of things to do. The smaller 58" version I built several years ago and passed on to Dave Chinnery turned out ok because of the heavy 600 can motors, but with lighter brushless motors it's an issue. I imagine that it will be less of a problem with i/c engines, particularly if a chunky four stroke is chosen. The key is to get weight into the front end of the nacelles, because the nose is too short and well behind the spinners. Quote Link to comment Share on other sites More sharing options...
A.A. Barry Posted August 2, 2014 Share Posted August 2, 2014 Percy, Vance's build has been continued on by other members of RCS, mainly by Warbird Colors owner Chuck and who also has taken over Vanguard plans and kits. Vance and I spoke a few times and I obtained an orig. plan of the W.W., but what was fesible then (3mts ) is now not, a great loss, was the passing of a master builder In regards to the C/G , if the rear is kept really, really light, with I.C installed, is not a problem,as with the 2 I have built and flown sucessfully.1 still sits quietly waiting.(as per avatar) My pilot was , on an engine quit, suprised that there was no noticable flight narsties, and landed as per normal I envisage the next one will be E.P, and the 2 lipo's crammed into the nose, well forward Barry Quote Link to comment Share on other sites More sharing options...

The answer is to use two Lipos and put one in each nacelle, well forward. That's on my list of things to do. Dylan/Colin I was just wondering, with the lipos in the nacelles as per Colin's suggestion, what kind of size would be the minimum before there wasn't any room to fit retracts?

Colin Leighfield Posted August 4, 2014 Share Posted August 4, 2014 David, I couldn't answer your question directly, but I think that because the nacelles are so wide in diameter and project well in front of the wing, that you should be able to fit in any likely Lipos without compromising the retracts. Dylan's CAD peojections should reveal all. A.A. Barry's observations about keeping the back end light can't be argued with, but with brushless motors the cg might still be an issue. There's only one way to find out. Quote Link to comment Share on other sites More sharing options...

Colin Leighfield Posted August 4, 2014 Share Posted August 4, 2014 Once Dylan's done the CAD work, scaling up and down should be straightforward David, you'll get there. Quote Link to comment Share on other sites More sharing options...

A.A. Barry Posted August 4, 2014 Share Posted August 4, 2014 Interesting where Dylan came by the wing rib profile, on the Whirly, as it's not original ????? Barry Quote Link to comment Share on other sites More sharing options...
Dylan Reynolds LaserCraft Services Posted August 5, 2014 Author Share Posted August 5, 2014 The wing rib profile is from my stock of known stable profiles and is being tested on the first build. A true profile can sometimes create construction difficulties but will be looked into once the existing design is proven. Quote Link to comment Share on other sites More sharing options...
A.A. Barry Posted September 2, 2014 Share Posted September 2, 2014 Dylan, any updates on the Whirly size and kit yet?? barry Quote Link to comment Share on other sites More sharing options...
Dylan Reynolds LaserCraft Services Posted September 2, 2014 Author Share Posted September 2, 2014 Things are in progress with the 96" one and shouldn't be too long before its proven or not, untill then I don't really want to do too much regards to the smaller design, although a start has been made Quote Link to comment Share on other sites More sharing options...
David Pearce 4 Posted September 2, 2014 Share Posted September 2, 2014 I'm still very interested in a smaller version, as discussed previously. But I am in no rush, plenty of others to build and fly! Quote Link to comment Share on other sites More sharing options...
