  1. Test flew on Saturday last week with recommended set up and movements.   She would not clime and control was almost impossible and she crashed, braking her neck and tail. Solution move motor thrust line through C of G   Added another sheet on top, curved to give a wing profile and increased the ailerons by 75mm.   Result she flies …….   Now to paint
  2. Hi Pirune I found a local supply of an alternative to Blue foam, Jewson stock cavity insulation board called …..Recticel cavity batts. It is an extruded polystyrene with foil both faces. The Foil is easy to removed. The foam is very light weight. When sanded there are a few open cells but they can be filled with one fill polyfiller.   I then glass clothed is with 0.6oz cloth and Ezee coat by Delux Materials.
  3. Hi Guys I started my own building blog and should have checks to see if one already existing. I have built two of these beasties and my mate test flu the first one while I have been on holiday.   As there was no guidance on the drawings I set the initial trust angle 0 degrees, with the motor parallel with the wing. She went for ground on power and broke her neck.  Second flight at around 15 degrees, motor pointing at the tail she wouldn't climb under power.  Glenn, Clark and Simon all report similar problems did you solve them….help…
  4. You may have noticed I have actually built two of these beasties. My mate test flu the first one while I have been on holiday.  Initial reports are the thrust angle is wrong and the C of G needs to be 10mm back from the recommended position.  On the maiden with power on the thing headed for the ground, initial trust angle 0 degrees, with the motor parallel with the wing.  Second flight at around 15 degrees, motor pointing at the tail she wouldn't climb under power and ailerons non responsive.  The drawings have no recommended thrust angel so time to seek advice can anyone help?
  5. Well I test flew before paining and the thrust angle and C of G were all wrong   On power and she headed for the ground and broke her neck.   Will glue the head back on looking up thus setting the motor pointing to the tail rather than parallel with the body.   Will up date again soon.Edited By Stephen Stokes on 22/08/2010 08:38:37

  7. No rods in the wings, there is a 3mm rod in the head and the tail.I have used 0.6oz glass cloth wrapped around the leading edge and around the tail. This has made them very stiff, and light.  The shiney strip on the wing is 25mm glass tape, dont think it need it.   
  8. A littel ProgressTail on Glassed LE and tailControll surfaces added and servos installed    
  9. Painted the head with deluxe materials Flexikote Glued it to the body To get the motor thrust angle I pushed a 1m long 8mm tube into the motor mount tube in the back of its head. With this I could check alignment.    
  10. Well a bit of progress. Found a local supply of an alternative to Blue foam, Jewson stock cavity insulation board called …..Recticel cavity batts. It is an extruded polystyrene with foil both faces. The Foil is easy to removed. The foam is very light weight. When sanded there are a few open cells but they can be filled with one fill polyfiller.    Also made some claws, Used garden wire and a pot of chemical metal from Halfords.     Didn’t like the Cyril Carr version for a head so drew one myself, my 12 years old son also had a go and as his version was better than mine that’s what I built.     Motor mount to the back of the head with a 10mm aluminium tube glued in to hold the bell motor. Just push the motor into the tube.   As you can tell my model shop supplier so far is Jewsons and Halfords…nice and cheep.
  11. No worries Did a bit or research and played around with the depron an dent it to shape. will post some buld pic as I go.
