The tiled plan is on page 1. The attached untiled plan was prepared with iText and ScaleAndTile3.

You're very welcome, Tony. I know that untiling a tiled PDF is not that easy to do. With iText, OTOH, it's not as hard as unscrambling an egg. ;-)

Nope, don't have a wattmeter (although I just made a shunt for my multimeter from the instructions in another thread here, and it seems to work fine). I can't use that now with these motors to check on them, because they're both dead!

I used Webocalc to check on the amps I would be drawing before I flew them...with the 1500KV version, I was using an 8x4 prop on a 2S 1700mah pack. Should have been around 10amps. Each one flew the plane fine, but the first one died after 3 flights, and the second died after two.

But as many people have said, the quality of these motors is inconsistent, and I'm willing to consider that I just got two very bad ones.

Well, I did a dumb thing, I think: The leading edges of my tail feathers were getting a bit ruffled so I decided to trim them down a little - thinking that I'd reduce drag and fly alittle faster too... I made the stabs and control surfaces all about an inch shorter, plus trimmed a little of the depth off give me clean new edges. Now it feels like I just don't make very nice turns anymore. Either I need to beef up the motor for more speed, or make new tail feathers to give me back the low-speed control.

IMHO... you need to go back to the original size tailfeathers. Thinning them down wouldn't have any impact, but cutting down the surface area is a bigee. More power wouldn't help you much either since BB's don't need it. Bob

It's not nice to mess with Mother Nature.

Seriously Warhead, the BB has pretty big tailfeathers for extreme stability (it IS a trainer, right?). Cutting down an inch on the stabs shouldn't make a huge difference, but it will make a difference. Your problem is probably in the fin/rudder. It has to counter considerable side area forward of the CG and a small difference could have a larger effect on it's turning quality. Pretty simple to fix though.

Blu-Baby Bash Bonanza or BBBB?

Just wanted to float an idea that I PM'd Tony about. Here is a JPEG output from TurboCad of a 3D model of a Blu-Baby inspired Bonanza. Is it worth the effort?

Does that stubby little cub sitting on top of the TV fly?

If so.. Does it do it well?

If so.. Is it a plan or a kit?
