  1. Hi Stephen, I made the bottom fuselage half to begin sizing bits and pieces for the EDF conversion. The fan fits nicely between F8b and F9b and gives an exhaust cone that fits the technical requirements almost spot on. It looks like it will fit on the motor line you used for the prop version. The wing ducts will be too small so I decided I would need "cheater holes" to allow more air in the fuselage. I decided that I may as well use scale holes so I'm adding retractable landing gear and not closing off the wheel wells so the air can get in. That should open up plenty of extra air and I will make plastic scoops in the wing ducts so that that air is smooth coming in. The scale location looks to be between F5b and F6b. because of the extra weight I need extra performance so I'm using a 4S battery. I originally wanted to load it through the nose cone but the nose wheel foils that so I'm going with two 2S wired in series and located low down on each side of the fuselage. This will leave the centre for the Rx and ESC. The extra performance should be around 29 oz. of static thrust. So I think I will get away with it. I won't make the EDF a permanent fixture until I have it all working correctly. Will post some pictures when I do a bit more carpentry.
  2. Hi Steve, what a quirky and neat model. Looking at the plan it shows the booms skinned in Ply but the legend says balsa. Which do you recommend? I have a great planes Synchro that has a 56mm EDF that may just work. The exhaust will be 50mm so not so scale but I can do retracts and the servos will also fit. So good bye Synchro, hello SIPA S.200. I plan to use the wing ducts plus a cheater hole in the fuselage for air. Jack Higgins Toronto.
  3. Anyone know where you could buy scale spinners for the Short Solent Mk. lV? Papa, Toronto.
  4. Thank you BEB. I went back and took another run at it and found it. Dec 2010 and Jan 2011. Thank you now back to our 6" of snow and -26C tonight. Imagine that in a shed no wonder we all have basements. Jack.
  5. Hi can anyone tell me the dates of the magazines that carried the articles by Tony Nyhuis on his FG technique? I'm doing my nut here and not finding them. Thank you. Jack Higgins, Toronto.
  6. Thank you both, I will try Southampton and also check Profili for something akin to those numbers. They would not have used an RAF airfoil would they? Jack.
  7. Hi, does anyone know what airfoil was used on the A-1 jet fighter flying boat? Thank you, Jack Higgins. Toronto.
  8. @import url(/CuteEditor_Files/public_forums.css); It was a year before I realized the 'E' stood for Electronics. I thought it was Electrics.

  9. Good morning Tim. The satellite had just failed for no apparent reason. When tested it was just dead. Never been crashed etc. Everything worked fine when a new satellite was installed and rebound. That is until it all failed.  Jack HigginsToronto.
  10. We just had an AR7000 go off at the field. A new Hanger 9 Mustang on a maiden. Complete write off. As the pilot sensed a loss of signal the retracts started to deploy The model just went straight in from about a hundred feet. Transmitter and Rx have been returned to Horizon at their request. If we get an answer I will post it here. The satellite had been replaced with a new one a week before. Two good lights on start up so the Rx seemed OK. Jack Higgins Toronto.  
  11. It's got to be 14. My last address in Dublin.
  12. Good evening Steve, check out this video and you will see the speed of the electric retracts. Not quiet prototype but not Bang Bang either. Jack Higgins http://www.youtube.com/watch?v=N_s0vFIvfjo&feature=player_embedded   
  13. I hope you will consider using electric retracts rather than the an air system. They are the future to my way of thinking.. Jack.
  14. Great plan of an intriguing prototype. Congratulations Glenn. The original had the winglets at 23 degrees and yours are a lot less. Was there design reason for that? Jack Higgins
  15. Since the wheels go into the wing root could you open the top of the wing so the wheels protrude into the fuselage? This would keep the wing thickness at scale but it might be tricky to keep the strength. Jack Higgins.
