Martin McIntosh Posted March 11, 2017 Share Posted March 11, 2017 I really do not need any more models but wanted something to keep me busy over the winter which this certainly did. Still in mourning over my lost TN 132" Lanc. I just had to make another, but this time electric and of a more manageable size. I could have done the TN 72" one but wanted something a little larger which I could call my own, so I started with just the 3 views. The chosen size was very easy to scale up, just measure to within 1/64 inch and multiply by 3.2. Even to five decimal places the dimensions came out to nice round numbers in inches. I have added as much detail as I am capable of but drew the line at putting 1:15 little men in it, sorry. Still some gun barrels to add but I need to fly it first. I took it to the field today to take the pics. and do some taxiing trials. There was very nearly air under the wheels on a fast run over as yet unmown grass. As you will see the wiring was a nightmare, especially since I had to move a battery rearwards to get the cg somewhere near. I have tried a new way of opening the bomb doors using a couple of small retract units. Maiden will take place as soon as the patch has been sorted out.

Piers Bowlan Posted March 11, 2017 Share Posted March 11, 2017 Amazing project Martin, really very impressive. How long did it take? And how did you come to lose the TN 132in Lanc. or is that still too painful to talk about? Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted March 12, 2017 Author Share Posted March 12, 2017 Thanks guys. I started drawing this at the beginning of November. I was rather ill at the time and needed something to keep me busy but not requiring too much physical effort. The big one? I wanted to win the local club scale comp. and took off in a crosswind. It weather cocked towards two large trees so I stupidly applied aileron instead of rudder to correct. It opposite yawed making matters worse, stalled and turned 180 degrees downwind. End of model. If I had kept the acetate and glass mouldings I may have built another. Despite much goading by club members I was not about to make the same mistake again. Just taxiing around showed up a couple of things which required a little attention such as a screw needed in the rear wing tube which pulled out slightly on full power and the need for thread lock on the u/c grub screws.

John Laverick Posted March 12, 2017 Share Posted March 12, 2017 That's super Martin, an excellent model. Had to chuckle at your birds nests!! Do you ever revisit a model, especially a fully functional multi motor, look at the wiring and think "someone else must have done that, cos I can't remember being that capable" ?

Denis Watkins Posted March 12, 2017 Share Posted March 12, 2017 Martin, to me this is the extreme end of our hobby, demonstrating beauty, single mindedness, and the absolute skill of success. Broken down into small tasks there is nothing that we allcannot do But the assembly is a Huge Beautiful Lanc, Many thanks for sharing Quote Link to comment Share on other sites More sharing options...
Robert Parker Posted March 12, 2017 Share Posted March 12, 2017 Hi Martin, What a fantastic job you have made of your Lancaster. You must be feeling very proud and quite rightly so. good luck with the maiden Regards Robert Quote Link to comment Share on other sites More sharing options...

Martin McIntosh Posted March 12, 2017 Author Share Posted March 12, 2017 Thanks again. By far the hardest job was pulling the canopy and turrets. I have done a little of this before with some hit and miss success but despite building a better vacuum box the creasing got me nearly tearing my hair out. Got through an 8x4 sheet of PETG! The wiring originally looked a little less scary than it does now but having to move the main batteries back a lot put paid to my bespoke looms. I was not about to start that lot again. Quite a lot is crammed in there, six wing servos, two retract units, four motors with very heavy duty wiring, four ESC`s, rudder and elevator servos, two extra retract units, three nav. lights, home spun strobe unit plus switcher, four battery packs and a Failover switch. Oh, and there is a Rx and two satellites buried amongst that lot somewhere. Martin Quote Link to comment Share on other sites More sharing options...

Martin McIntosh Posted March 12, 2017 Author Share Posted March 12, 2017 I know Tom, but there is no space whatsoever to fit tanks and throttle servos. Even on the 132" one I had to settle for 6 and 8oz fuel tanks. Four OS 26`s would stick out all over the place and there is nothing smaller. Add 4x glow drivers and their batteries and switches for safety and -------! Could always fit a sound module or two but I need to get it flown before thinking of such things.

Martin McIntosh Posted March 12, 2017 Author Share Posted March 12, 2017 And I thought that you were a petrol head like me! I tolerate electrics and it makes much more sense for multi engined models, having tried both. Looking at my hangarful now, electric ones seem to be taking over. They just sound `orrible or not at all. Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted April 6, 2017 Author Share Posted April 6, 2017 Today I am afraid I ran out of excuses, the wind being near perfect, so full power and fingers crossed. I need not have worried. After 60m it sailed off no problem, just four clicks of up and it was flying straight and level. I just need to add more aileron/rudder coupling. Power is adequate but not excessive. Maybe 35/30 motors instead of 28/30`s would have been better. I made two circuits and decided to land so that everything can be checked over and the battery usage measured. Landing needed a fair amount of power to be left on. I did not need to try the flaps as yet. And no, nothing fell out Cymaz. A few club members suddenly appeared just before take off, as they do, one videoing it with his mobile. Yeeha, couple of sherbets to celebrate.

Denis Watkins Posted April 6, 2017 Share Posted April 6, 2017 You are a brave man Martin, and gave good observations for all of us, namely not to power off and attempt any sort of glide in. This had to be a " fly to the ground " ; wheels touching the deck, before power off, model, if you get my drift Have no hesitation in 50% rudder to aileron mix with such a model as yours, giving you time to observe the graceful Lanc How spectacular are your efforts, thankyou Quote Link to comment Share on other sites More sharing options...
