Here's some preliminary plans... no C.G. or equiptment placement.

Ooops, the file is too big! Zipping it still only got it down to 275K. Oh well.


Willin,
the rouned edges on the fuselage are sanded and the rounded edges on the stabs are burnisned with a rod or tube. The wing leading edge is folded.

Missing Servo Screws


HOLY COW! OMG! I could have been KILLED while filming. Run for COVER!!!



Bill,

Great job on the copy. I hope you have a motor that will spin that prop at 26K plus. I still can't believe how FAST the Insulator is. I may have to build one, TOO!

servo screws


Bill- Good eye, the screws are missing. I've been doing that for the last two years! Haven't had one pop off yet, saves a little weight(I think) I'm really not that concerned about it in a plane that costs me about $1. I guess I should be concerned about the $25 lipos in the nose when it comes crashing down, though. I'll worry about that when it happens, which is inevitable.

Build one


Gary- I have a video camera when you get yours in the air, WooHoo! Insulator combat! P.S. you should be worried for your life everytime I fly, I'm never REALLY in control! Wooah ha ha ha ha.

Cool!


Looks pretty mean, Is that motor a pretty hot one? Good luck with the maiden, any video? Even pics would be cool. Is that skid carbon fiber over foam?

It's pushing nearly 10 oz's thrust on a 6 oz flying weight.

motor


Bill- Is that motor pushing 10oz on 2 cells or 3? How did you configure that thing? Delta/wye, turns, wire? Sounds like a mach 2 flyer.

I'm using a 3 cell 700ma pack and a 5x4.3 prop. The motor is delta. At full throttle it pulls about 5.2 amps. The ESC (CC10) gets hot for some reason.

Last night, I was sitting on the floor and ran the motor up.....it made the ceiling fan blades begin to turn.

Well it flew farther than a "Lawn Dart" but the results were the same

. I gluded it back together, moved the battery foward 3/4", reduced the throws and it flew like a champ or should I say a Bat Out Of H*LL!

At full throttle it blew the hatch. I brought it down and re-taped it. Gave it a toss and it sank out of site in a drainage ditch so I gunned it and gave it some up and it shot up back into site...wheew it's fast for a foamy. I was most comfortable at half throttle which was still reasonably fast.

It's ugly now but at least it flys and is quite stable.
