Well, flew with a buddy yesterday, trying out the new twin boom (only pic I have. Wings were red cote, booms, elevator and mount were black:
got a grand total of 2 flights
Holy cow that sucker was fast. The .061 wasp turned 3 sec laps on 35 foot lines, bout 50 mph (6X2 APC props ROCK!). Well, I only 1/4 filled the tank and forgot and the engine cut out in a loop, kinda came down hard, but everything looked okay, so I filled her up a full 1 oz, cranked her up and let her rip on a light 2 stroke break.
Turned 2 laps to build up venturi speed, did a slow climb, into a dive for a tight loop (love 'em). Soon as I gave it up a stiff up elevator, it stood on its tail, engine cut off and it nosed over, CRUNCH, ripped the motor mount off, splintered the main interior fuse, turned 5 ribs to toothpicks and tore off several square inches of mono.
I was like what the H? Never had one do that to me before. I mean no sputter, no slow down, just screaming banshee to silence at the twitch of my wrist. So I tore down the engine, could'nt find anything wrong there, then checked the fuel lines, all good. Well the plane was toast so why not rip out the clunk tank?
Soon as I did, I saw it. Clunk line had come off the brass tube inside the tank. This caused the tube to be able to pick up fuel in level flight or light climbs , but as soon as I stood it on its tail, it was sucking air
.
I've now fixed all my tanks with the clear nylon hoses on the gas line instead of the brass tube. They allow you to put the tube further into the take up hose to prevent slips.
That was a killer plane too. I could probably fix it, but in the time it would take to strip it down, cut all the parts out again, rebuild, recover and repaint, I could do a whole nother plane. Going to try a larger built up wing version of this:
Thinking about 30" span round 200 square, round a 12" fuse and a hidden wing tank.
Looks like the wall of shame has another trophy.
