cymaz Posted June 5, 2022 Share Posted June 5, 2022 (edited) After starting the Stampe blog 10 years ago (!), and being a team member of the DB Giant Mannock build, I thought it would be a great time to start another topic. Since I lost my much loved 4 engine scratch built I was at a loss. Then I saw that TN Design had a Lancaster suitable for 4 x .40 size engines, not too large at 134” span....Great! Having spoken to my build mate Brian, he’s up for it! The Savox servos, new Futaba Rx and full kit will be purchased over the next few days/ weeks. I’ll post as often as I can.

Cliff Bastow Posted June 5, 2022 Share Posted June 5, 2022 Watching this with great interest. I have his smaller Avro York and found it well designed and goes together well. Quite a lot of sanding to shape though! It flies really nicely. Cliff Bastow. Quote Link to comment Share on other sites More sharing options...

cymaz Posted June 8, 2022 Author Share Posted June 8, 2022 (edited) First of the goodies have turned up.....the tick end of £350 !! The four mini servos will drive each throttle. The rest are for flying surfaces. I’ve managed to bind the Rx to my Futaba 18mz. Set up was easier...and getting more so with practice. With the Tx, it decides which channel is allocated. So far it’s been good, all four throttles work together. Edited June 8, 2022 by cymaz Quote Link to comment Share on other sites More sharing options...

cymaz Posted June 8, 2022 Author Share Posted June 8, 2022 In some way correct the extra channels you can rename and move but I left it to it...page 65 I think Quote Link to comment Share on other sites More sharing options...
cymaz Posted June 9, 2022 Author Share Posted June 9, 2022 (edited) Spent a productive hour getting all the channels to work including the landing lights. The R7014sb is easy to program. I’ve changed the DG2 port from Sbus to ordinary switching channel. On the Tx I’ve managed to use the gear switch for DG1. This means that the landing light switch woks with the gear. If anyone wants me to go into it a bit deeper, I will. For now I need a sit down ! As of now the channel count is... 4 throttle 2 rudder 2 elevator 2 aileron 1 gear 1 port for power 1 DG port for lights 1 DG spare switching port.

cymaz Posted June 9, 2022 Author Share Posted June 9, 2022 (edited) DG1 port is now working, it’s on the same switch as the gear. When the gear goes down the landing lights are on. DG2 port is now navigational lights. It’s on the throttle kill switch, the lights are always on but turn off when the throttle kill is activated. This might change in the future.....I hope not. I’ve had an email from TN saying the kit should be arriving around the 20 June Edited June 9, 2022 by cymaz Quote Link to comment Share on other sites More sharing options...
cymaz Posted June 11, 2022 Author Share Posted June 11, 2022 I can confirm from Futaba USA and my own experience that you can plug the Rx power supply into either DG ports. I did change them from s-bus to normal mode before hand.....not that makes any difference, I don’t know Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted June 11, 2022 Share Posted June 11, 2022 When you say 4x40 motors, are they the two strokes from your o/d? From my experience the model needs 12x6 props. I have found my fg cowl mould but it is pretty ropy, probably from when I had compatibility problems with the resin and thickening agent types.

cymaz Posted June 11, 2022 Author Share Posted June 11, 2022 Yes, there’s 4 x OS 40la motors from the old airframe. They were utterly reliable. Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted June 11, 2022 Share Posted June 11, 2022 I used 2x OS52FS inboard and 2x OS26FS outboard because on paper that should have been enough compared with the original 4x 600 brushed motors. It was but left nothing in reserve. Also, with all the intelligent on board glow drivers and associated sub c batteries there was only room for 6oz tanks on the outers and 8oz on the inners but not a problem with the motors used. The 52s were on 12x6 and the 26s on 12x5 after an extra shim in each head and 20% nitro gave respectable RPM. Whilst constructing mine I watched one being flown on 4x 40 two strokes and it went like a bat out of hell, even low inverted. Quote Link to comment Share on other sites More sharing options...
cymaz Posted June 11, 2022 Author Share Posted June 11, 2022 Many thanks for the feedback. We’ve studied the plans and reckon that Dubro 12oz tanks will fit. It might take some head scratching but there’s no rush. Brian ( the main man as builder) is a clever chap and we’ll work something out.

cymaz Posted June 17, 2022 Author Share Posted June 17, 2022 (edited) Not much going on...waiting for the kit to arrive. It should be here around the 20th June, give or take a few days. When I’ve finished the painting on the Giant Mannock I will then start on doing the mock up of the port wing landing lights. I’ve also managed to find a second Haynes book on the Lancaster. This might be a good reference for insignia, lights, windows etc. Edited June 17, 2022 by cymaz 1 Quote Link to comment Share on other sites More sharing options...
cymaz Posted June 19, 2022 Author Share Posted June 19, 2022 Quick proof of concept and roughed up something this morning. I’m still not sure about the door hinges. I took out the separate screws and used a single rod. This made it easier to line everything up. 1 Quote Link to comment Share on other sites More sharing options...
cymaz Posted July 7, 2022 Author Share Posted July 7, 2022 (edited) According to the helpful staff at Hendon, the landing lights were angled inside the wing with a Perspex shield.. I am thinking also of the variant to build. I’m leaning toward Coastal Command colours. My late dad was in CC and stationed at St. Eval Anyone know of a good pictorial source?? “Thank you for your email. The underwing lights were fixed in place, but they were angled slightly forwards behind the glazing. The first squadron to be equipped with the Lancaster ASR3, for air sea rescue duties, was 179 at St Eval. After that a number of St Eval based squadrons flew either the ASR3, or GR3, variant of the Lancaster. “ Edited July 7, 2022 by cymaz Quote Link to comment Share on other sites More sharing options...
cymaz Posted July 31, 2022 Author Share Posted July 31, 2022 I’ve been industrious. I have bought 4xSC46s. Now call me reckless but I reckon it could work out better. There is one of the local clubs that is a bit tight for take-off space. All the engines have been stripped, cleaned and new parts ordered....bearings, head shims and carb O rings. I’ll stick them all on the engine run bench and set the carb arms using my trusted wire and protractor method. If anyone is interested I will post the pictures and do a quick explanation. The kit has now “landed” at Builder Brian. So hopefully, we can get started in a week or two. 3 Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted July 31, 2022 Share Posted July 31, 2022 Quote I thought that you already had 4x 2st motors from your defunct weirdo. Should be rather more than enough power though. Saw one fly on 4x 40`s. I shall be interested in knowing what the wing ribs are made of having presumably come from SLEC. Quote Link to comment Share on other sites More sharing options...
cymaz Posted July 31, 2022 Author Share Posted July 31, 2022 Martin, you are correct. I know it’s a bit of a departure but I get the same Slec engine mounts it should be just a case of swapping out the engine plus mount. This should give me a relatively pain/ stress free method of doing an engine swap....we shall see. Quote Link to comment Share on other sites More sharing options...
cymaz Posted August 13, 2022 Author Share Posted August 13, 2022 Ive now completed the 4 engine test runs. These are lovely engines. Still pondering over prop sizes but this will wait until it’s built and we can do some proper ground testing. I might make a 4 engine test ring using the intended Rx and servos if anyone wants to see it! 2 Quote Link to comment Share on other sites More sharing options...
