  1. Forming/Curving Depron etc - The Easy Way! The need for making a former is mandatory! The materials I use, Thin Plywood and Soft Thin Aluminium Sheet        1/2" Pine or Deal, Make the airfoil sections you nail the Ply or Aluminium Formers too! So making the outline profile used in the moulding of the wing section ? The Good bit is you can make many Depron Profiles of that wing! using this same pattern My larger wings have a 3mm Depron skin on the botTom with Depron Ribs and Carbon Fibre spars (PoundLand Fishing rods!)   The above is the hard work bit! The standard way to Curve Depron is to Slit/Notch/Groove it etc to make it easier to curve or shape ! Depron users know about its 'Grain' How it Curves easier and 90deg round its not easier. Now Shaping Depron is so easy,You do not need to Groove it etc. Along with the heat guns  glazed effect that makes it much thinner! Due to the heat increasing by going to close A Rapid test! Switch on The Electric Kettle, Get a piece of scrap Depron, pour the boiling water into a bowel, Put the "long" scrap of depron into the bowel and see how easy it is to bend or straighten, then bend it again, Pour in cold water to cool it down, Straighten it; now?          I use a rectangular plastic box, obtainable in most kitchenware shops, A baby bath would do, depends on your model wing size? The made up "wing section" requires a stand that allows it to sit  Level inside the box. The Stand must all be "Underneath" the wing section!!! I use a rectangular piece of linen with 3/8" brass rods attached to the front and rear of it, (The material should long enough to stop the weights sitting on the Depron)  For pulling the Depron down on to the wing section, So shaping it, "When the boiling water has been applied!" The Depron must placed accurately on top of the wing section, With a Plastic headed pins pushed in at an angle at each end to locate firmly! I only make parallel chord wings now, Largest a home brew Super 60" All my small Planes use the 6mm Depron, with the trailing edge profiled (Hot wire) With Struts or Solid 2mm Carbon Fibre spars When PoundLand opened up, I purchased quite a lot of SuperGlue by MaxiFix 10g Last week on check testing it on Depron, My lucks in !!! Any help Just Shout Hope this will help Deproners, Phil Woods
  2. Giant cod,   The site is down and will be for about two days !  I have been trying to get in to no avail and then I read about site failure from Rob Carpentar himself !  Phil W    
  3.  Ok on all remarks Rob, Here is a lift off from a site:  "The SP18A ESC is as mentioned else where"- a little rough on start up,-- but is fine once the prop has gone past a very slow tickover.......First bad comment read about the  SP18a ESC. Fine on the HiModel 'FLY' 12A, The 7 grams is nice but the 12 amp is on the motor limit and I tend to go 50% more to make up for my forgetfulness ! The Fus is finished,The wings are now jigged  and tomorrow the glueing ceremony takes place !               A Sopwith Pup and a SE5A  are in my attic, all flyable but not by me as I don't have a Transit van now .        The grandweans will be noisy though when the tripe wings !  Thanks, Phil           
  4. Ok Rob, The inertial effect crossed my mind as well, tried minus prop - no joy ! The Keda ESC on 3cells now starts smoothly,  but I can't afford the weight and don't want to use a smaller prop. A 7" prop is needed for the RCME Sopwith Triplane, with 2cell lipo to ease the CoG problem . At 80 Its tempus fugus, In my working life problem solving was a norm ! Now its time for me to get aquainted with the Triplane. Regards, Phil 
  5. Thanks for the response! When I connected the  EMAX CF2805 motor to my SP 18A ESC I was taken aback at the noise ... The motor heat wasn't great, BUT for the length of time it was on it  surprised me. I only use brushless outrunner motors  and as stated, My "Keda 25amp ESC" and "SP 18A ESC",drive many other brushless outrunner motors I have, very smoothly indeed ! Using Keda 25amp ESC, The motor gives a little grunt then speeds up smoothly ?  Both of my CF2805's react in the same way ! A  timing or phasing problem would affect my my motors, Surely ! The top combo is a lethal for motor and ESC for sure and I would like to know the answer ? Regards, Phil  A retired electrical tech
  6. My EMAX CF2805 motor is not working with a SP 18A ESC, Turns About 2 turns a second vibrating like hell (It won't speed up at all ?) Using a Keda 25amp ESC I have, The motor gives a grunt then speeds up smoothly ? My other CF2805 does the same ! So Its usable with the Keda 25amp ESC and will power the Sopwith Triplane nae bother ! Any Resolvement/Answer on hand on this problem ? Both motors are new and unused in a model ! My Keda 25amp ESC and SP 18A ESC,drive other motors I have very smoothly. Phil A retired electrical tech
  7. The Pilot not  sitting in the rear seat rather spoils the picture for me ! It is a scale  model aircraft and scale means realism to me !
