Out yesterday to test my repairs of my Slow Stick. After the last tree crash, I figured I had pulled too much dihedral out of the wing with that carbon fiber reinforcing rod. Since I had epoxied that rod in, it was NOT coming back out. So I just cut it. That put flex back in the wing.
Soooo - out to try. BUT.... same symptom. It flew just fine until, all of the sudden out of nowhere, once again it lost all lift on the LEFT wing and rolls nose first in to the ground. Just like before. But no tree to cushion the impact this time.
I'm stumped as to the cause. Now I'm wondering if it wasn't something like a cracked wing mount or something - that would do fine until just the right stress - when it would start to give. But after this crash it's almost impossible to tell now. Both wing mounts destroyed. Motor mount destroyed. When testing on the bench I found the ONLY thing that survived were the servos and the receiver. The speed controller was shot - first time I've lost one of those in a crash. The motor was shot. It took the brunt of the hit - in fact was buried in the mud. The battery was crushed to where I didn't trust it anymore. So I discharged it last night for the trash. (Yes, Lipos are safe to throw in the trash - once discharged. Not toxic.) And, of course, the airframe pretty much completely destroyed. Even the fiberglass "stick" fuselage was split lengthwise. I ?may? be able to salvage the tail feathers - although even back there the fuselage is split slightly (rudder/elevator epoxied on.) But little stress back there so I think I could repair it.
Now, for the kicker. GWS has DISCONTINUED these kits. They used to go from $25-$30 for the basic air frame. The last kit I saw sell was on ebay. Some guy auctioned it off. An opened kit, even, so no guarantees of what it included. I bid $60 max. The kit ended up selling for $115!!!! So they are as rare as hen's teeth now. I can find nothing out there.
So.... I have *ONE* kit in stock remaining. I could build what is, in effect, a whole new Slow Stick. Or I can go for a third party type kit. Hobbyking has one - with ailerons for about $90 I think. And StevensAero has designed a wooden wing that will go on a Slow Stick. It, too, has ailerons. Orrrrr - I could just build my last GWS kit.
I haven't decided yet. But "Phoenix" is a gonner. I'm afraid it's now in Slow Stick heaven with my other old one, "TIMEX".... Sigh.....
It was an expensive crash, too, as I normally run pretty top quality, high cost, components. I figure why risk an airplane to save a few bucks on cheap stuff. Soooo - the ESC: about $50. Motor: $60. Battery: $20. Airframe: Not replaceable anymore. Ugh..... Add everything all up - including the small stuff, and probably around a $150 crash. Sigh.... That's bad enough, but when I crash and never know WHY..... well THAT bugs me... Se la vi.
