S4Simon Posted April 15, 2019 Share Posted April 15, 2019 Last year at a model competition I bought an old (very old) Tamiya Lancaster Bomber kit (1975), with the hope of building it into a diorama. I've been searching for years for a person who would have some sort of computer kit that would initiate the engine sequence in a realistic way. Anyway this year I found a source that supplies the computer and other hardware, I just had to source a soundtrack + extras to make it look cool. So what started out as a simple build has turned into a monster task, which I'm happy to say I'm still just on top of. The build is still in progress, but the progress has been positive thus far. Anyway here's some pics of the build to date. Currently the wings are in the paintshop. Enjoy the pics and vids.

dogsbody Posted April 15, 2019 Share Posted April 15, 2019 You should check on the usual engine starting sequence on Lancasters and your engines are rotating the wrong direction. Otherwise, a bold and ambitious plan that's looking good. Chris Quote Link to post Share on other sites
S4Simon Posted April 18, 2019 Author Share Posted April 18, 2019 Thanks for your interest Chris. I've investigated the start up sequence on a few Lanc videos, and it does depend on who's flying the plane, safety on the day. The most common is (if looking at the front of the plane with number one on the left) 2,1,3,4. For me I'm not that fussed about sequence, it's all about putting on a show for the model show audience. At the moment sequence will be 3,2,4,1. This is also due to the fact that I have to add different weights to each propeller so as to get the smooth shutdown right. Nothings ever easy. Presently just blue tac stuck to the props and they're not balanced that well. Also the problem with my prop rotation, the motors i'm using are pulse width modulated and I don't believe I can reverse the polarity whilst running load resistors on the negative side. I could be wrong. Each negative wire is wired separately onto the cct bd and the positives are joined to a common voltage rail. Might do a bit of reading to see if there is an easy solution, otherwise they'll be left as negative thrust engines 😉 Wings are now out of the paintshop. Fair bit of touching up to do before they're good to go. On a break for a couple of weeeks. Then we'll get stuck into the wing wiring integration into the fuselage and start on the fuselage painting.

dogsbody Posted April 18, 2019 Share Posted April 18, 2019 To be honest, I didn't check on the start-up sequence of a Lanc. I just remembered that I have a Pilot's Notes booklet. As for the wiring set up, I only vaguely understood what you said. Other than very basic wiring knowledge, that may as well been printed in another language. It's looking good, though.

S4Simon Posted April 28, 2019 Author Share Posted April 28, 2019 Wing update - They're pretty much finished. Using a masking kit so as not to have to use the supplied 40 year old decals. Next weekend I'll start on the fuselage. Quote Link to post Share on other sites
S4Simon Posted May 5, 2019 Author Share Posted May 5, 2019 Fuselage works have commenced. Become very fiddly now. Wing Wiring has been fed into the fuselage, and now its just a mumble jumble rats nest of wiring. Next weekend is making it all pretty - the wiring that is. And I'll feed it all through a new hole behind the tail wheel. 4 Months of work completed, only 2 months to go before completion. Quote Link to post Share on other sites
phantom Posted May 6, 2019 Share Posted May 6, 2019 Very nice, your brave doing the decals before the paint is done. I would be afraid the decals would peel off when I removed the mask. Quote Link to post Share on other sites
barkin mad Posted May 8, 2019 Share Posted May 8, 2019 It's coming together. Should be good when finished. If you were not already aware, that part under the canopy should be in the local camouflage colour, probably dark green. ------------------- Quote Link to post Share on other sites
S4Simon Posted May 8, 2019 Author Share Posted May 8, 2019 Interesting. I didn’t pick that up. I’ll investigate. I also have a problem with the props rotating in the wrong direction, but that’s a little harder to fix as the motors are pulse width modulated, so it’s not as simple as reversing the polarity.

S4Simon Posted May 11, 2019 Author Share Posted May 11, 2019 A lot of testing this weekend. Making sure not to sever any wires as I sealed up the fuselage. Good news is that it all still works. Fuselage painting complete. Oh - and I went with green under the canopy 🙂 Next weekend I can start on fitting the gun turrets, tail plane and bomb bay. Quote Link to post Share on other sites
dnl42 Posted May 11, 2019 Share Posted May 11, 2019 Nice work! And the decals survived! Quote Link to post Share on other sites

S4Simon Posted May 15, 2019 Author Share Posted May 15, 2019 Mid week progress. Weights added to props and test run okay. Lighting testing okay. Might do a small adjustment to one of the props and then I can put them all on properly. Then starts the weathering and work on the diorama base. Added a few pics and a short vid at the bottom. 🙂 https://youtu.be/lP_gm1ELFNc Quote Link to post Share on other sites
S4Simon Posted May 17, 2019 Author Share Posted May 17, 2019 Laying the turf tonight. Tomorrow I'll try and dull it down a bit due to it being a little heavy on the GREEN side. PS - Advice on using 40 year old decals. Don't. They just turn to dust when you touch them. Quote Link to post Share on other sites
S4Simon Posted May 18, 2019 Author Share Posted May 18, 2019 OK we're all done. 200 hours to complete the diorama. Grass has been dulled down and all the wiring is now hidden, and still works. Vids to follow. Thanks for all your kind comments along the way. 🙂 Quote Link to post Share on other sites

cag_200 Posted June 9, 2019 Share Posted June 9, 2019 (edited) Wow.. That is really nice! Why the parts on the backside of the rotorblades? Is it weight? Yes...ok..just read it is but for what purpose? Edited June 9, 2019 by cag_200 Quote Link to post Share on other sites
S4Simon Posted June 10, 2019 Author Share Posted June 10, 2019 The computer shuts down the motors in the same sequence as startup. The weights cause the motors to stop in a different sequence and better aligns with the soundtrack. Quote Link to post Share on other sites
