3D Micro size. Videos added.

I had to give something like this a try.
I scaled down some plans and began scouring the internet for what to outfit a tiny plane like this with. I found that to be harder than figuring out what I need in my 40% Giant scale plane..

I found http://www.airmidimicros.com and begand talking with Mike there.
SUPER helpful and he set me straight on what I needed for a plane like this.

I got some plans and had Craig Koerner scale them down to a 16" wingspan.
I made this first one out of 3mm depron but have some 2mm depron I will try on the next one.
It may not work out because the 2mm seems a lot more flimsy without much of a weight savings over the 3mm

Stuff started showing up in the mail this week and I was blown away at how small the compenents are.
The next task was to solder connectors onto the servos.. My eyes were going nuts looking at this stuff without a magnifying glass of some sort.

I got it all framed up and installed everything.
Final weight with the battery is 1oz (29 grams)

I put 6 flights on it tonight and its REALLY cool! Its a little tailheavy and that showed up in some things when it was flying. Not bad at all though.
The next one will have a longer nose moment.

Hovering, Upright and Inverted Harriers, Knife Edge, inside and outside Loops, Rolls, Rolling Circles were all no problem with it.

Heres whats in it.

Gasperin Potensky Wasp Motor
Micro Invent MBC3 ESC
Micro Invent 5x3 CF prop.
Minor Flat 5 CH RX
3- Toki servos
Micro Invent 1S 150 Lipo

Pics of it sitting on the cowl of my 40% Extra..

Nice!

A lot of folks have been asking around for something like this for a while. That's almost 'Aero Ace' sized. How are your flight times? A guess that really depends on how hard you push it, eh? How do you find the muscle wire servos? It's my understanding that they use power all the time out of the neutral position. How does that effect flight time?

I flew for about 5 minutes each time and landed before I felt any real drop in power.
The servos seemed fine. They slow down if you are working them hard for an extended period of time but once you give them a chance to go back to center and pause, they are back at full speed.
Its not something I noticed inflight.. I saw it on the ground.

Nice work mate.

Ive just about finished my little 3d. It looks the same as yours, uses 3 Toki servos also but weighs only 15g AUW with a 10" WS. I should have it ready by the weekend.
Everything is installed, just got some pesky soldering to do now...

I hope it will fly! Fingers crossed

Ive got some photos on my phone but can't get them off for some reason Nokia PC suite is playing up on me but i'll work on that little problem soon also

Well done!

PS: Need we ask for a flight video?

Very cool.
I'd love to see some pics when you can get it worked out.

Wayne,

Look at you. Does BBW now = Built by Wayne?

That pic of the foamy on your Godfrey cowl is cool!

What colors/scheme are you gonna do?

Around 370 for electronics.
Not cheap right now but, I am sure prices will go down as time goes by.

That's frigging awesome dude! Well done.

Well it looks as if those Tokis are doing their job.

Do you think you could use a slightly larger prop? It should give you more lift out of the inverted hover... but then again what do i know, you'll probably ruin it

Once again, well done
