...an interesting turn of events
From the first few flights it was apparent that, in my opinion, the little Fox was over-propped, especially running just an 1800mAh battery. Also, the R2Hobbies spinner setup is very dodgy - the inset pivots mean the props cannot fold flat as they foul the fuselage by a mile, and the prop mounts only fit a 6mm base, meaning the props have to be filed thinner to fit, weakening them considerably.
I discovered this first-hand when, landing the Fox with the prop still windmilling because of the unbraked ESC, a sudden snap indicated that one of the prop blades had given up. Consequently I've ordered a new 32mm carbon spinner and a 9.5x9 carbon folding prop to match, slightly smaller than the original prop to spin a little more freely.
I've also ordered a 25-50C 1800 nanotech battery to give the Fox a little more grunt than the pedestrian pack it's running on at the moment. However the biggest surprise came from the spare parts shelf.
Hunting around for a replacement prop, I came across some Walrus props, about 8.5 size, which I thought might do in the meantime, and filed these down to suit the Fox's mini-mounts. As well as being a bit smaller, the Walrus props are also cranked forwards which help the props to clear the body and fold better.
Not expecting too much, in fact virtually expecting the rework white plastic blades to disintegrate at the first hint of full throttle, I was amazed at how sweetly they worked, with the Fox humming happily through the cool morning air...
