Chuck,

what a beautiful rendition of the little Brushfire! I'm sure Ken will be duly impressed (as am I!). I hope he's subscribed to this thread.

Your description of the plans in post #10 is correct. I produced the tiled version so that I could print and assemble at home. Attached is a (poor) snap of my tiled plan. You can see that it's half span is barely shy of 20" - this is due to the tiling and excess cutting and assembly process. If the wing came in at 38" span (actually 38.4"), I have the feeling it is due to your printer scaling down letter size printouts to 96%. This is pretty common and is done to ensure content is kept within margins - my HP laser printer (on which the plans shown were printed) does this by default. In order to print to scale I have to tell it to scale to none. Do you think this is what might have happened?

That aside, at 40", I think a 15 would be at the upper end of the desired power (perhaps a K&B 18 tops). I really custom tailored the plans to fit the Webra 12 with pipe as shown higher up in the thread. At 38" (closer to Rainedave's original scaling), we're really talking about a Brushfire 10.

With that said... you absolutely must finish that jewel! At 38.5", she'd be ideally suited for an OS 10 FSR, a ST X11 or similar. You could put a 2.5cc macs pipe off the side of any of these engines but it probably would be just fine an ounce or so lighter without the pipe and a muffler. Alternatively, you could venture into the wild and bolt an outrunner on to her, forget the landing gear and go have fun at your local high school!

If you're really set on building a 40-42" span version (42" would be better for a Mag 15), I'd absolutely love to finish her! She looks like a diamond in the rough to my eyes! I could see if the Webra 12 fits but I think at that scale, I'd really be inclined to putting the other Pico motor I picked up.

I could send her back to you with a 1/2 page "how to fly a 10 karat electric Brushfire" instruction sheet. But you probably wouldn't need it...

Man... nice job! Does the entire foam deck come off? Looks like the wing is permanently attached - make's sense. All access must be through the canopy. It also looks like you brought the fuse sides down to the bottom plan line and used tri stock for the joint. That's what I planned to do too. They're nice plans.

David.

P.S. I re-uploaded the plans in post #10 as files with PDF extensions. No need to rename extensions any more as PDF is now supported on our forum.
