cymaz Posted May 5 Author Share Posted May 5 (edited) The wing is off the board and trial fitting of the nacelles. Also I raided the piggy bank ( again! And show signs of severe malnutrition) and bought a Unilight controller for the navigation, landing and rear marker lights. I have so say...they are very bright indeed 😎 😎 Edited May 5 by cymaz Quote Link to comment Share on other sites More sharing options...
cymaz Posted May 12 Author Share Posted May 12 (edited) More work done with the lighting. I won’t bore you all with the story of who I reached this stage. It was a case of several failed versions and a lot of head scratching. First job was to get it all roughed out on card. And finally..... Here it is at work, the light will come on.....promise Edited May 12 by cymaz 4 Quote Link to comment Share on other sites More sharing options...
stu knowles Posted May 12 Share Posted May 12 I think that that's a great job although perhaps I would have used a 9 gramme servo rather than a standard. Quote Link to comment Share on other sites More sharing options...

I don’t think I’ve a good 9g servo. The next job is to make the two new brass arms using the ply as a template. I’ve ordered some Paxolin which will be the final piece of the puzzle Quote Link to comment Share on other sites More sharing options...
Chris Walby Posted May 13 Share Posted May 13 IMO don't forget you are effectively applying air brakes, ok if you deploy at landing approach speed but anything faster and certainly at high air speeds where will be quite a opposition force. PS if you are unfortunate and burn one servo out with it fully deployed and retract the other light things might get quite exciting. 1 Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted May 14 Share Posted May 14 If you arrange the o/p arm to be in line with the servo body there will be zero force on it when the lights are deployed. I always set up flaps like that, having learned by burning out four retract servos on the bomb doors on my version of the model. 1 1 Quote Link to comment Share on other sites More sharing options...
Paul De Tourtoulon Posted May 14 Share Posted May 14 Use the throttle / brake set up that we use on rc cars with double springs, here only showing one. Quote Link to comment Share on other sites More sharing options...
cymaz Posted May 17 Author Share Posted May 17 I might experiment with the springs, good idea The pivot is silver soldered now and I’m pleased. The arms are straight and parallel and they fit nicely together with the light heat sink. JB weld will keep it altogether, or m2 bolts …not decided yet Quote Link to comment Share on other sites More sharing options...
cymaz Posted May 17 Author Share Posted May 17 Nah… I decided to bolt a plate through to the aluminium plate. Much safer and more rigid. The fuel tube is to stop wire rub 2 Quote Link to comment Share on other sites More sharing options...

cymaz Posted June 7 Author Share Posted June 7 Ok, another version of the landing lights. Very pleased with this…smaller, lighter and easier to adjust 1 Quote Link to comment Share on other sites More sharing options...
cymaz Posted June 15 Author Share Posted June 15 (edited) Beginning of the wire runs. To help the pull throughs, I’ve used some 1 ltr drinks bottles, cutting the bottom and neck off. Rolling these up tight they slip into the rib holes. Once released the plastic springs tight into the holes. A dab of hole glue keeps everything in place. Different types of string will aid the installation Edited June 15 by cymaz 1 Quote Link to comment Share on other sites More sharing options...

cymaz Posted July 1 Author Share Posted July 1 All done. The idea is to put a couple of hatches in the top of the wing to aid installation and service 1 Quote Link to comment Share on other sites More sharing options...
cymaz Posted September 6 Author Share Posted September 6 Wings now fully sheeted. I’ve decided to use very fine nylon and Ploy-C from RC World. I’ve got a friend with a 3D printer and this is the result! The last pair is already with Brian.. 2 Quote Link to comment Share on other sites More sharing options...
cymaz Posted September 6 Author Share Posted September 6 The port wing is upside down. There’s the aileron to hinge, nav light to have its cover glued on the the retracting landing light to finalise 8 Quote Link to comment Share on other sites More sharing options...
cymaz Posted September 6 Author Share Posted September 6 Thanks for the 💙… I might not get around to covering until late September/ early October but I’ll try to be on it asap Quote Link to comment Share on other sites More sharing options...
cymaz Posted September 9 Author Share Posted September 9 Another job I forgot to mention was I’ve just put a Cortex gyro in my old Seagull Dual Ace. The DA was a test bed for the Lancaster engines. It’s now another job to do, to test the viability of the gyro on a multi-engine model. Quote Link to comment Share on other sites More sharing options...
cymaz Posted September 10 Author Share Posted September 10 All morning to install the landing lights and aileron servo…what is wrong with me 😝 IMG_0078.mov 1 Quote Link to comment Share on other sites More sharing options...
cymaz Posted September 10 Author Share Posted September 10 The gap at the front of the lights is to let it come over the pocket edge. I’ve spent a hour or so making a couple of jigs for the flat hinges. The angle is about 45’ which seems to allow plenty of movement on the mock up… 1 Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted September 10 Share Posted September 10 Not as yet quite sure what you are up to from those pics but I expect that it will become clear later. Do remember that TN models are not generally as light as they could be, especially the laser cut ones, so I would be careful with the details you are adding. Otherwise, your build looks very impressive. Mine took 5 years on and off it. Quote Link to comment Share on other sites More sharing options...
