Pulse jet day at Bennett airfield in Las Vegas

Post  Dane Martin on Sat Aug 20, 2016 2:31 pm

Today was a short day. Daviny wasn't in the mood to fly jets all day. I didn't bring her plane. I got a nice surprise that her mom dropped her off to me early. She is more of a muffled 1/2A flyer.

Any way, got a video of the second flight. Dane Martin flying,  Joey mathison and Tony Drago getting it started and launched properly. Definitely a learned technique to that business!

Man, when it lights off, it's outta there. Looks like you lean back against it pretty hard too. And when it's done it cuts off as fast as it lit. How much fuel did that flight use?

I've never seen one fly in real life. Dan Banjock brought his to Huntersville, but wasn't allowed to fly since it's a landfill, still actively venting. That's kind of ambiguous, we burn glow fuel, smoke cigarettes and charge Lipos in the open, but them's the rules.

Thanks for the video

Thanks guys. It's a blessing having a multiple time nats champ teaching me the art of speed flying. Which, BTW, I need lots more practice!

Rusty, that flight was 5 oz I believe. At 11 laps. Well 10.5 running laps. I'll double check the tank size though. That plane is 33.5 oz. The pull test is 42 G. So that's an 88 lb pull test.

The next days flights were better. I should have had someone record that last one on Sunday. I levelled it out better, and man did it feel faster!

That's the way it happens with me too. There is a video of Philly Flyer Dan Banjock flying a full pattern. I think it's said he used a quart of fuel. Talk about slinging a firebomb, Lol.

EDIT: Well I may be wrong about the pattern, but maybe not the quart. This is at Huntersville the year before I joined. I didn't think he'd ever been allowed to fly them there.

Rusty, Dan's plane won't make the pattern with a full tank. His flights were 18 oz's but he he increased the hopper and I believe he now has 21 oz's. This is also not a straight mix of gasoline. Propylene oxide is also added to the gasoline. The main problem is the CG shift. The tank is right on the nose of the plane and when it depletes the  plane becomes very tail heavy. Landing becomes difficult because you can smack the tail pipe on the ground.

That's really fun watching Dan fly. I'd like to fly with him one day.
I will build a jet stunter one day. But I got a fever..... and the only prescription is speed! Lol. Speed flying is very unique. Looks easy, but turns out its very technical and challenging. Just like other aspects of the hobby. I certainly don't want to take away from other disciplines.

Actually, I'm diving head first into F2d combat now. Probably because it's fast...... lol
