Yeah, I thought you had built other stuff. It's all just one long learning process.

Whew, I am glad to see that you didn't give up. I remember all those posts, and your planes, I just didn't put it all together when I saw this most recent post. I panicked and quickly replied that you should hang in there before I did any research. Its all good...

here's a video of my UM Monocoupe. It ended up needing a little noseweight. AUW ended up being 1.7oz (48g).

In the works now is a Dehavilland DHC-2 Beaver...hopefully done in the next couple of weeks.

Beautiful, and it flies outside! Wow, at only 1.7 oz, very impressive. How much wind do you think you could put up with?

I think it was blowing somewhere around 4-7mph. as long as you can make headway, I guess it really doesn't matter. As long as you can get it down reasonably close to the ground, because it's so light, you can just plop it down into the grass and not worry about damage.

Is that the same Monocoupe from page 134?

Flying so nice in the 4-7 MPH wind is very encouraging, I was afraid you had to have zero wind or fly indoors, two things that are rare for me. So maybe I can take my E-Flight extra 300 out, as it has lots of power, and could fly in a similar wind.
The new 3 axis stabilization that E-Flight is offering would make that even better!

Vid of a micro Fw190 I've been working on with the intention of turning it into a kit - you may have already seen the build thread as I posted it up only this week, but thought I'd stick it on the ar6400 thread too as it uses an ar6400!

And I have had very few problems using the little Rx brick. Super reliable - the odd twitchy servo but all good generally. I'm also running a 1.7g rotary servo for aileron control and just experimenting with a brushless setup too.

Build thread is here:

Thanks, Bill.

Yes, your description of the Storch scooting around on the ground made me think of that video. It was definitely up to flying speed a couple of times there, but not flying. It looks like I had the battery most of the way back on the tail too, so it was just the thrust angle problem that was causing it, I think.

You can see in the first video that the motor was mounted a couple of inches above the nose, so that gives it quite a lot of down thrust if it's pointed level.

It was a crude attempt at something I'd seen done in a thread about a kite - vectored thrust with just two servos moving the motor and no moving control surfaces. He'd done it with proper gimbals though, whereas I'd just mounted one servo directly onto the horn of the other one, and strapped a motor mount to the second one.

Really, the motor needs to be mounted so it doesn't pull against a servo (which it did - the elevator servo had to struggle to keep it level as I increased the throttle). I think the thrust line needed to go through both pivot axes, and it probably needed a pull-pull arrangement on both servos moving a gimballed motor mount.

Deadbird,
I saw your build thread a couple if days ago and thought that it was one of the best looking profile build I've seen. That shading does wonders!

DeadBird,

What a beautiful plane! The detail is stunning, but the speed was a big surprise...
