cymaz Posted January 26, 2019 Author Share Posted January 26, 2019 As it is a wet Saturday in January, I thought I would get on and have something meaningful done by the end of the day. After finishing the epoxy and fibreglass cloth in the engine bay Friday night it was left to completely go off. Today’s job was get the choke and throttle runs in, servo tray built for that and run the cables....all done. Off shopping now so pictures to follow when we/ I get back, wet from Aldi Quote Link to comment Share on other sites More sharing options...
Bruce Collinson Posted January 26, 2019 Share Posted January 26, 2019 Peter, Mines 3.655 kg all in, dry, with a Laser 100. Does that sound about right? BTC Quote Link to comment Share on other sites More sharing options...
cymaz Posted January 26, 2019 Author Share Posted January 26, 2019 I will try and do a rough weigh-in Sunday, Moday Finished roughing in the control linkages, servo tray, plumbed in new pipework and tank fitted. The servo tray and new rear bracing, ( the original rear one was cut out to get the tank in) will stop the tank moving back and forth Edited By cymaz on 26/01/2019 18:40:56 Quote Link to comment Share on other sites More sharing options...

cymaz Posted January 27, 2019 Author Share Posted January 27, 2019 I will have to ditch the idea of the choke servo. The indent on the shaft is quite strong, too much for the servo. Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted January 27, 2019 Share Posted January 27, 2019 On one of my gassers I used a bellcrank so that the choke operating wire came out through the fuse. Just a thought. Quote Link to comment Share on other sites More sharing options...
cymaz Posted January 27, 2019 Author Share Posted January 27, 2019 You read my mind.....the principal of KISS should apply here. New servo tray to be made Quote Link to comment Share on other sites More sharing options...

Peter Jenkins Posted January 27, 2019 Share Posted January 27, 2019 Good solution. I've never liked choke rods coming out of the front of the cowl - don't know why though! Quote Link to comment Share on other sites More sharing options...
cymaz Posted January 27, 2019 Author Share Posted January 27, 2019 Well I thought it couldn’t get worse with the build quality . Unpacked the legs today to figure out the prop clearance. It’s a brand new model....check The legs well packed in foam...check Someone in quality control needs a good kicking... Put the legs on. They only fit on one way. As a result both legs are twisted and I hope show up on the photos. It’s not easy but you hopefully get the idea.... Score, -1/5 Anyhow, we soldier on. Fuel proofed the engine bay and landing mounting plate. Also fixed some wooden blocks to screw the other cowl half into Quote Link to comment Share on other sites More sharing options...
Peter Jenkins Posted January 27, 2019 Share Posted January 27, 2019 Would have been better if they had left then undrilled. Mind you, drilling the holes in the right place ain't a piece of cake either. Quote Link to comment Share on other sites More sharing options...
Bruce Collinson Posted January 27, 2019 Share Posted January 27, 2019 My legs needed one hole enlarging. I can readily foresee the current (I strongly suspect generic) two piece legs being swapped for a one piece composite u/c. There are already cracks in the paint on both faces. Had same issue with the Seagull Yak, and I didn’t even land it! I begin to wonder whether there might be a market for these ARTFs without any hardware, with a proportionate cost reduction, so the builder could specify and fit it to his own specification.

cymaz Posted January 28, 2019 Author Share Posted January 28, 2019 I think that is a good idea. Put the DLE 20ra on the test stand today. Will check the timing tonight and, hopefully, get it going tomorrow Quote Link to comment Share on other sites More sharing options...
Bruce Collinson Posted January 28, 2019 Share Posted January 28, 2019 Ooh err .... timing? You’re clearly writing from past experience but that wasn’t an issue with mine, once the jets were reset from fully closed. Might save time. Checking to see if Jeremy Harmer’s flew today, second attempt. Would have been fitting filter and rx had the present Mrs. C. not blocked the washing machine drain filter...again..............................😫 Quote Link to comment Share on other sites More sharing options...
cymaz Posted January 28, 2019 Author Share Posted January 28, 2019 Could you tell me his carb settings please. Is it ,H 1 1/2, L 1 1/4?. Quote Link to comment Share on other sites More sharing options...
Bruce Collinson Posted January 28, 2019 Share Posted January 28, 2019 His is glow. My DLE if I recall started out at 2 turns each then closed in progressively. The Chinese copy Walbros don’t seem to be very consistent, but the out of the box settings were a mile out. Sorry. Washer unblocked. Quote Link to comment Share on other sites More sharing options...
cymaz Posted January 29, 2019 Author Share Posted January 29, 2019 Finally......Finally....on this build something that works straight out of the box HERE Edited By cymaz on 29/01/2019 18:08:00 Quote Link to comment Share on other sites More sharing options...
Bruce Collinson Posted January 29, 2019 Share Posted January 29, 2019 That must be a relief and satisfying in equal measure; well done. Your identity is out of the bag now. How were the jets? B Quote Link to comment Share on other sites More sharing options...
cymaz Posted January 29, 2019 Author Share Posted January 29, 2019 I screwed the both all the way in and then turned them out. There is a bit of a write up on the video, Quote Link to comment Share on other sites More sharing options...
cymaz Posted February 2, 2019 Author Share Posted February 2, 2019 Spent as long as I could in an unheated garage. Did the final fix of the engine, ignition, pipework and tank. I’ve been advised that using closed loop for the elevators is not going to get the best of aerobatics. So I’ve bit the bullet and bought 2 of these, one for each half. They will be driven using the Futaba 9c Ailevator mix. I will use M3 linkage.. Quote Link to comment Share on other sites More sharing options...
Peter Jenkins Posted February 2, 2019 Share Posted February 2, 2019 Cymaz, I would have to disagree with the advice about closed loop elevator not being good for aerobatics. The Capiche 140 was a highly successful 3D and precision aerobatic machine and had closed loop elevators. Never fear, 2 mini servos are just as good and a lot easier to set up not having to cope with 6 closed loop wires. Quote Link to comment Share on other sites More sharing options...
cymaz Posted February 2, 2019 Author Share Posted February 2, 2019 I did the ailevator set up on the Dragon Lady ReFurb. It’s a doddle to do and works well. It will offer some redundancy on a vital surface. I can still use the elevator crank somewhere else. Quote Link to comment Share on other sites More sharing options...

cymaz Posted February 4, 2019 Author Share Posted February 4, 2019 Sunday morning, Mrs Cymaz hard at work, cats asleep, all the housework done. I set about doing the cowl. As in previous posts the engine bay continues to be an utter pita. I had to make a special length Allen key to tighten the exhaust bolts. Added litho plate to one side of the bay to protect the timing wires from exhaust heat. Various cardboard templates used to get the general shape of the baffling...more work to do but we are getting there. The baffles in the picture are of thin beer can to get the curve, this will be beefed up a bit as it’s paper thin and might bend. Out of the way of the incoming air flow. Engine bay.. Cowl.. Inner cowl Cowl front... Also servos and Rx coming today from Steve Webb Models Edited By cymaz on 04/02/2019 06:40:53 Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted February 4, 2019 Share Posted February 4, 2019 You will of course be dressing back that cutout in the f/g cowl leaving nicely radiused corners won't you? It's looking neat now but yes, what a royal PITA to get there! Shoulda gone electric Quote Link to comment Share on other sites More sharing options...
