Dan Workman Posted February 8, 2018 Share Posted February 8, 2018 Hi all i'm Dan, first post on here. Thought i'd share a project i have going at the moment. I drew it up on cad last year but have only got round to starting it a couple of weeks ago. I'm hoping to get it ready for the start of the season in April, so far i have the fuz pretty much built and i've started on the wings. Bit about the model, it has a deep fuselage with canalizer on top, anhedral tail and i'll be using a twin motor contra rotating motor. It's 2m long. The only thing i havent decided on is a colour scheme. Heres a few pics.... Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted February 8, 2018 Share Posted February 8, 2018 That's one intricate design Dan. Can I ask how long it took you to produce the detailed design work to the point of generating cutting files? It doesn't look to be a weekend project!

Dan Workman Posted February 8, 2018 Author Share Posted February 8, 2018 A couple of months i would say just in my spare time. However im no cad expert, i only work in 2d which has its limitations.Its very useful though, especially trying to get an f3a model as straight as possible, its a huge advantage.

Martyn K Posted February 8, 2018 Share Posted February 8, 2018 Hi DanWelcome to the forum. That looks great. Are you going to plank the fuselage?Martyn Quote Link to comment Share on other sites More sharing options...
Dan Workman Posted February 8, 2018 Author Share Posted February 8, 2018 Hi Martyn, yes the whole nose was planked, prob took about 3 evenings. The sides and rear turtle deck were straight forward but the nose was a pain! Quote Link to comment Share on other sites More sharing options...
Andy Meade Posted February 9, 2018 Share Posted February 9, 2018 Very neat work. That's a lovely shape you're creating there too Quote Link to comment Share on other sites More sharing options...
Dan Workman Posted February 9, 2018 Author Share Posted February 9, 2018 Thanks Andy. Its just a pain that lovely shapes are usually harder to make!! Quote Link to comment Share on other sites More sharing options...
Andy Meade Posted February 9, 2018 Share Posted February 9, 2018 Dan, are you related to Andy Workman? I used to work with him, and had a nephew (I think) that was into the aerobatic side of things. Quote Link to comment Share on other sites More sharing options...
Ultymate Posted February 9, 2018 Share Posted February 9, 2018 Hey up Dan, how you doing? having a bash at F3A are you ? Quote Link to comment Share on other sites More sharing options...
Martyn K Posted February 9, 2018 Share Posted February 9, 2018 It does look absolutely great. Also nice to see a bit of UK home grown creativity in the world of F3A. I assume that this will be electric powered. Martyn Quote Link to comment Share on other sites More sharing options...
Dan Workman Posted February 9, 2018 Author Share Posted February 9, 2018 Andy, i do have an uncle Andrew, he lives in Bromsgrove?Hi Brian how are you? Yeah doing a bit of f3a, this will be my second full year. I used another own design last year, it flew well but not as well as a Krill Spark i had so it never got used!Hi Martyn, thanks! Yes i'll be running a twin motor contra rotating set-up. Chap in poland makes them. I'll put some pics up laterDan Quote Link to comment Share on other sites More sharing options...

Dan I'm fine thanks Dan too old for all the travelling that goes with competing but still enjoying my flying. I'm sure given your experience in aerobatics you'll do OK Quote Link to comment Share on other sites More sharing options...
Geoff S Posted February 9, 2018 Share Posted February 9, 2018 One of our F3a members designs and builds his own models but his are moulded. He's Polish but won the Nationals in his class about 5 years ago. Dual contra rotating props seem to be the current 'Thing' in F3a and Les's are driven by 2 motors with (presumably) a hollow motor shaft in the front one and, obviously, 2 speed controllers. Dan's design looks stunning with those delicate fuselage formers. It looks to be very lightly constructed so I guess, like most these days, it's destined to be electrically powered? Look forward to see it gradually coming to fruition. Geoff Quote Link to comment Share on other sites More sharing options...
Dan Workman Posted February 9, 2018 Author Share Posted February 9, 2018 Hi Geoff yes i know Les, it was seeing his latest design flying that convinced me to get the same twin motor set-up as he's got. Adam Debowski who manufactures them is a very talented engineer, i think hes made about 8 units in total. Les is also a great builder, especially his moulded work. So yes being electric allows for a very light airframe without the need to reinforce for the vibration of a thudding YS. Although, i do like a YS, the latest being the YS200. It purrs but still vibrates a lot compared to electric. Quote Link to comment Share on other sites More sharing options...
Dan Workman Posted February 10, 2018 Author Share Posted February 10, 2018 Bit more of the sheeting process and the fin assembly. Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted February 10, 2018 Share Posted February 10, 2018 Looks amazing. Is that big engine with the blue head going in it. Steve Edited By Stephen Jones on 10/02/2018 16:57:24 Quote Link to comment Share on other sites More sharing options...

Gary Manuel Posted February 10, 2018 Share Posted February 10, 2018 Lovely build Dan. Watching with interest. Just one question. Do you need to take any measures to make sure the fuselage doesn't warp whilst the planking / sheeting is drying? Just asking because I've never done anything like that but I would expect there to be some movement going on as the planking dries. Quote Link to comment Share on other sites More sharing options...
Dan Workman Posted February 10, 2018 Author Share Posted February 10, 2018 Thanks guysSteve no thats a .21 buggy engine, not even sure it would turn a prop!Gary, the fuz is built without the bottom decking so can be pinned to the board. Once all the sheeting is on and dried it can be taken off and can put the bottom decking on. Quote Link to comment Share on other sites More sharing options...
Luther Oswalt Posted February 10, 2018 Share Posted February 10, 2018 Great job, absolutely top drawer! I will be watching this one for sure! Leo Quote Link to comment Share on other sites More sharing options...
Dan Workman Posted February 12, 2018 Author Share Posted February 12, 2018 Few more pics Getting towards the end of sheeting the fuz, which means the cutting the canopy out. I built the canopy base into the fuz so was just a case of finding the join and slicing through the skin. Then trimming back the front and rear to add new formers and face the canopy. I'll be honest, it was a bit of a pain! Oh and then do the latch. Most of the lower sheeting had been done, just got to cut the rudder out.

Ultymate Posted February 12, 2018 Share Posted February 12, 2018 Coming along great Dan ! A buggy 21 will turn a prop if you can cobble up a prop driver, I did it with an OPS when I was racing buggies Quote Link to comment Share on other sites More sharing options...
