I recently received a box of goodies containing items to finalise the Fox glider; a 32mm carbon spinner, a pair of carbon 9.5x5 folding props and a new battery. The reason for changing from the standard setup was that the R2hobbies spinner has an inboard pivot which prevents the prop from folding, and additionally I thought the standard 10x6 props too large.
On the weekend I had a chance to get the Fox out for a trial run with its new hardware, and got something of a surprise; the setup, powered by a 25-5-C 1800 Nanotech, developed that much thrust that it put the Fox into a turn at full throttle, and caused a vibration past about 80% throttle.
Consequently I've decided to try out a set of Walrus props I've got in the spares drawer. These are about 8x5 and I think should be a little more suitable. Anyhow, I've got the Fox set up and will give it another test flight soon...
