  1. Thanks for the info Martian, have taken a few more photo's outdoors, as the ones in the shed dont really do it justice
  2. Thanks Martian, do you know the rough sizes that you made your spreader box?

  4. Martian, the build is almost complete with the exception of the dusting system. Am hoping for maiden flight on the Tues after Xmas (weather permitting). I also still need to get the decals sorted as I am doing it in the "westwick Distributors" scheme as this was a local company that was based at Ludham airfield andi have found some old photo's of their Pawnee's. will take some pics later today and post them on here. Peter thanks for that info. Will get the maiden sorted and then get the extraction system fitted.
  5. Am now sitting and wondering if i can modify the wing as the spreader needs to sit directly beneath the wing for it to look right. I have had to re-do the top of the cockpit as the plan shows it tapers sharply from front to back which is wrong and proved to be impossible to glaze the cockpit doors because of the differing angles. i have modded the U/carriage from how it is in the photo as it looks completely wrong.

  6. Yes I have now decided to go with the hopper/spreader system. I like the model you have built it looks really good Martian. That spreader you have come up with looks good, I am going to have to put the feed to the spreader further forward as i have left it to late in the build to run it through the wing. Do the slots at the front give a good flow of powder through the vanes? Andy, I have built mine from the Traplet plan by Herman Grobler to 72" span, but I must say that it not a very good plan, there are a number of errors and information on the plan is minimal to say the least !!!
  7. Thanks Gordon, Yes it seems the water idea is a non starter, my only concern with the smoke idea is to make sure I dont restrict the exhaust and stop the engine running properly. I have been thinking that as some of them used a spreader system from a hopper that it might be better to run the exhaust through that rather than nozzles along the wing?
  8. I am building a Piper Pawnee and have been trying to get a system working to spray water to replicate the real thing. I have tried quite a few ideas (not very successfully). The main problem with using water is getting a pump with a high enough pressure to spray out of nozzles for the whole span (73". Also with a 16oz fuel tank full of water it is emptied in less than 10 seconds. This set me wondering if a smoke system might be able to give the right effect through multiple nozzles???
  9. So far I haven't set anything on the transmitter, I am setting the arms forward so give a mechanical differential as they are on a Y lead, but one servo moves equally in each direction but the other moves more one way then the other, which wouldn't be so bad if it moved more in the opposite direction as I could take some movement out on the positioning on the servo arms, but I cant get more in.
