On sunday, I took the opportunity to have many helpers on the slope to experiment a smoke system on my Pike Precision. The reason behind is that I'm preparing an Air show that is end of september, using EPP jet plane with propeller, and I wanted to try this model of smoke cartridge on a larger model first. To do so, I build removable cartridge mounts. They are made of a 32mm water tube support and 2 epoxy plate (1mm thick). The 2 plates pinches the wing tip of the wing, and are secured with strong duck tape. The cartridge is just inserted in the mount, and doesn't move.
http://www.bjornax.se. I bought 2 different cartridges. The AX-18 and the larger model, the AX-60 as I don't know which one is the most convenient for the application. This time on the Pike, I used the AX-60. It provide about 4 minutes of smoke which can be white or coloured.
The flight went well, but at the end of the flight, I discovered that the cartridge melted partially because of the heat dissipated, wow ... hopefully, my mount was putting the cartridge far enough from the wing tip to not damage it .
