cymaz Posted August 27, 2023 Author Share Posted August 27, 2023 (edited) Brian and I inch ever closer to the conclusion of the first phase of the nacelles build....I’ve seen a couple of builds now that have had to make the same mods that we’ve done. Simply because we haven’t used the retracts that were designed for the airframe in the first place. Extra bearers along the sides and mounting plates Edited August 27, 2023 by cymaz Quote Link to comment Share on other sites More sharing options...
cymaz Posted August 31, 2023 Author Share Posted August 31, 2023 (edited) Whilst Brian is busy on the nacelles, I’ve been working on electrical connections. I’d thought about buying ready made multiservo connectors for wings and the detachable tail section. I bought the items form Component Shop, made the mistake of ordering too many servo extensions...Hey they’ll be used at some point. And they’re all upside down! My ratchet crimping tool just accepts the pins. The pins fit nicely into the housings and I did test the first pair with servos and a servo tester. No issues. Once that was done the wires were encased in hot glue to offer some strain relief Edited August 31, 2023 by cymaz 1 Quote Link to comment Share on other sites More sharing options...
cymaz Posted December 9, 2023 Author Share Posted December 9, 2023 Sorry it’s been so long. we can’t get on with the build, we’ll do wings first but are waiting on Slec to have 1” phelonic tube in stock. 1 Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted December 9, 2023 Share Posted December 9, 2023 Worth waiting for because it sounds a better and simpler option to the method shown on the plan. Quote Link to comment Share on other sites More sharing options...
cymaz Posted December 9, 2023 Author Share Posted December 9, 2023 Thanks Martin, all will be revealed over the next few months. We've also, ( Brian’s idea), decided to add flaps! Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted December 10, 2023 Share Posted December 10, 2023 You probably will not need to use them but I added flaps to my 81" leccy one. The inner flaps are fixed to the rear of the nacelles which retract inside the front part, as per the full size. Quote Link to comment Share on other sites More sharing options...
chris collis Posted December 10, 2023 Share Posted December 10, 2023 I would suggest adding flaps in the build as they do make a difference,After restoring my two 136in Lancs,I retro fitted them and they did enhance their flight characteristics.Both were Pss models and flaps really helped with flight and landings. 1 Quote Link to comment Share on other sites More sharing options...
cymaz Posted March 31 Author Share Posted March 31 Ok, Brian is now 100% better, with no foot infection. He’s laid out the wing ribs and the wing tubes are dry fitted. Flaps will not now be added. He’s been out of action for a year now with his foot and other issues but there’s now light at the end of the tunnel and he’s champing at the bit to get going. 1 Quote Link to comment Share on other sites More sharing options...
cymaz Posted April 1 Author Share Posted April 1 Well, Brian’s not been asleep! The nacelles were all built first, the wing ribs can be adjusted to suit, and we know the retracts all work ok. It appears that the build tabs on the wing ribs are missing from the cutting sheets so a packing piece is put in to compensate... I’ve been through all my engines for the project and run them up again. Two need new bearings as they weren’t changed when I bought them. I’ve 7 SC46s for the build. They’ll be run up again and the best 4 will go in the plane. 6A8DBC9E-AC1E-4E5D-BFB9-C0416B1DCF72.MOV 1 Quote Link to comment Share on other sites More sharing options...
cymaz Posted April 2 Author Share Posted April 2 These next set of photos show the wing rib tabs that Brian made that were not cut on the balsa sheets but are shown on the plans. He is also modifying the LE sheeting to make it more robust. The rear and front formers of B4 are also shown as a dry fit. He has mentioned that, though big, it’s not a complicated build....” there’s just a an enormous amount of wood” 1 Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted April 3 Share Posted April 3 What do you intend to sheet the wing with? I seem to remember that the plan states 1/16th (original electric version) but it needs 3/32nd otherwise your fingers will keep going through. I once met a guy who did his in 1/16th then regretted it. Quote Link to comment Share on other sites More sharing options...

cymaz Posted April 6 Author Share Posted April 6 (edited) It is going to be sheeted with 1/8 thick balsa. I’m looking if anyone could laser cut 24 off 50mmx50mm with a 36mm hole in the centre, 1/16 lite ply. This will support the large wing tube.

Martin McIntosh Posted April 6 Share Posted April 6 I fear that yours is going to gain a lot of weight if you mean to sheet the whole wing in 1/8th, double the weight of the skin shown on the plan and there will be an awful lot of it. That massive front tube will certainly not need ply either side of the ribs. One piece at the centre and outer followed by 1/8th balsa on one side only for the rest since the loading will be quite low. The inner ribs against the fus. take most of it.

cymaz Posted April 6 Author Share Posted April 6 Thanks for the input. Brian is following plan, ( with exception of the tubes). So I don’t think he will sheet the entire wing, I’ll ask to double check. 👌 Quote Link to comment Share on other sites More sharing options...
cymaz Posted April 6 Author Share Posted April 6 I’m going to put all the Lancaster engines in my Dual Ace twin. That way I can run up the engines in the air and see how they all perform in an airframe before they go in, better that way I think. Don’t know why I didn’t think of this before.....!
