Tom Wright 2 Posted January 5, 2015 Author Share Posted January 5, 2015 The video shows a rog of frozen snow in virtually nil wind and it was my partners first attempt to use a small sports cam,hence the near domestic at the beginning and end . The blades used for this test were a very old set made from all balsa with a six inch length of mm piano wire let in mm back from the l/e and extending from the tip towards the root .The rear section is preformed balsa trailing edge section with a piece of 6 mm x 25 mm balsa added so the amount of profiling and sanding is reduced to a minimum . The flight was fraught with distraction as my partner was convinced the cam had shut down and she could not see the model on the screen anyway , but the object of the exercise can be clearly seen as the model takes off in a short distance into very near calm wind, and despite the fact this one is no light weight very slow high alpha passes were possible. Clearly if good blade stiffness can be achieved light blades correctly weighted do seem to spin up very readily. Martin over on the ATOM thread has come up with another interesting variation on a similar blade construction but has added 1/4 square spruce at a point were little or no sanding is needed well worth a look for those interested in experimenting with home made blades. Happy new year to all Tom. Quote Link to comment Share on other sites More sharing options...

Tom Wright 2 Posted January 11, 2015 Author Share Posted January 11, 2015 Got fed up waiting for the wind to drop so it was off to the field today with my rudder controlled wing assisted Gyro. XC was showing 20 gusting 41 mph so this would be quite a challenge for a light gyro with no roll control on the head.Although these conditions could not not be recommended for newbies I was very pleasantly surprised by the way the model penetrated and how easy it was to control in the vicious wind, even managed to keep it on its feet on touch down .

Tom Wright 2 Posted January 11, 2015 Author Share Posted January 11, 2015 For anyone who might be interested the old blade set used on the model above has a depron core sheeted top and bottom with 1/16 balsa , with a wire leading edge covered with self adhesive glass tape, The stiffness and strength in bending is very good but this may also be due to the unusually thick section that has the normal 30% chord bolt location but the section max thickness is at 50% . The fast spin up and plentiful lift also returns very good low speed performance in calm conditions. The model uses turned up tips on the wing and tail which results in a rock solid sit in roll and a nice flat turns , pitch is controlled by a simple pivot and single 9 gm mg servo . The model is often used as a test bed for various rotor sets and is very relaxing to fly as a winter hack ,despite the deviations from the norm. Tom.
