RE: (Something Fast?) Delta Build Thread

Got a few more flights in this weekend and getting the motor dialed in more. I'm up to 20,400RPM on 7.5X8 Q40 prop on 15% still. Motor finally sounds like it's connecting on the pipe but may be...

RE: (Something Fast?) Delta Build Thread

Why not just add some plywood skids to the bottom of the plane; one near the nose and two out by the tips. If you land on asphalt then you don't have to worry about rocks and grass damaging your...

RE: (Something Fast?) Delta Build Thread

Neu Motors makes the 1907/1Y. They are getting used a bit in ducted fans now. Try his motor calculator @ www.neumotors.com
or try here too: http://brantuas.com/ezcalc/dma1.asp

Video finally done. Enjoy!

ps: any of the well tuned ears out there... this run was fairly rich (about 1200RPM low) but it still doesn't seem to...

RE: (Something Fast?) Delta Build Thread

Well today I got some more good flights in!:D I also got some decent video of the Demon Tiger which should be uploaded by tomorrow night (sorry to tease). I am still working on getting the motor to...

RE: (Something Fast?) Delta Build Thread

Maiden Report!! I guess it was a good weekend for maidens on the Demons. :D Mine went quite well requiring only a few clicks of down and a couple on the ailerons. I flew about 1/2" forward on the...

RE: (Something Fast?) Delta Build Thread

I have been working steady on the Demon and finally finished covering. There are really only minor things to finish up before I get to fire it up and go for a maiden. I did another Tiger scheme to...

RE: (Something Fast?) Delta Build Thread

Thanks guys! I'm going to get it flying first minus the 'full cowl' but the front of the motor behind the spinner has a smooth transition right now. I am finishing up beefing up the mount rails and...

RE: (Something Fast?) Delta Build Thread

I have been having too much fun flying and taking the kid to the park/beach/zoo/circus so progress was slower than usual. I made up some time figuring out my servo mounts, linkage covers, and...

RE: (Something Fast?) Delta Build Thread

I plan to smooth out the area behind the spinner and blend it back into the airframe. I will likely cut a ply ring and then build off of that.

RE: (Something Fast?) Delta Build Thread

I was wondering if anyone would notice those tiny winglets. I was just day-dreaming with with one of the winglets off of my recently dusted Beach Bumm flying wing. I will be laying up some carbon...

RE: (Something Fast?) Delta Build Thread

I am gaining progress on my build. It's going fast now that the sheeting is started. Figuring out the tank compartment and future aerodynamic cowlings took some head scratching time. I will be...

RE: (Something Fast?) Delta Build Thread

Thanks, I did find one here on RCU a guy was selling. This will help my build immensely. Now to drill some holes in the ribs for spars and start collecting my wood together.

RE: (Something Fast?) Delta Build Thread

I am now in the head scratching mode with a potential issue. If you look at this pic you'll see the straight rear exhaust manifold and an 8oz tank behind the motor. This is everything lined up on...

RE: (Something Fast?) Delta Build Thread

Well Mike, I actually broke out my Demon plans and cut my ribs out tonight. I need to order a couple of spars but I believe I have most of the other wood in my pile-o-wood collection. I had fired...

RE: (Something Fast?) Delta Build Thread

Goose, I would be leary about using a 60 amp esc and a peak amp draw of 80 amps. The issue is that when running at partial throttle you actually heat the esc up more than when at full throttle. So...

Yep, Carlsbad. We don't have grass but we have a smooth dirt runway. We're near the beach, not the desert ;)

RE: (Something Fast?) Delta Build Thread

Mike, a fellow pilot at my local field picked one of your kits up and I'm excited to take a closer look. I need something noisy to go with the over powered Shrikes at my field... He's gonna use an...

RE: (Something Fast?) Delta Build Thread

The Axi is a great line of motors but maybe not the right piece of equipment for a 200+mph goal. I'd look at a Neu Motor if you're willing to spring for a big Axi.

RE: (Something Fast?) Delta Build Thread

I guess you won't know until you try but there is going to be a lot of potential 'P' factor with a 12-13" prop. It may want to torque a bunch on launch with short coupled verticals. I'd make...
