Very impressive aircraft and flying skills to match. Operates well in confined spaces.

It is flying there now

24" and under planes are working great with 17 turn brushless cd rom motors, hitec 55 or blue bird servos (we've tried lighter servos but have not found any that can take the abuse)
A 2 or 3 cell 340 to 800mah lipoly
2 cells work well with the GWS 8040 (8x4) direct drive prop (aka Hyper Drive prop)
3 cells work well with the GWS 7035 (7x3.5) direct drive prop (aka HD prop)

Hi Sloper Steve,

A few questions:

1. Could it be made out of fanfold foam?

2. Where does the carbon spar with the elevator support go?

3. Landing gear?

4. The club I belong to, MARCEE, is doing a group build of GoBrushless motors this month. There should be about 30 of us building 50 motors over 2 sessions. We have been discussing what to put all those motors into and one of our members, Steve Pauley, is designing a balsa airplane. However, some of us think that foam is useful for more than just cooling beverages. Would you be flattered or annoyed if we bought a bundle of fanfold, cut our own kits, and did a group build? This would not be a commercial venture, we would just use your plans to cut kits at cost for club members.

Thanks,

Steve

I like it!

But first, let me commend you on the music! It's nice, IMO, to hear something other than the ubiquitous rock music in most everybody else's videos. But then, I'm a trumpet player & old jazz nut. Was that Miles & Trane? What was the name of that song?

Thank you for your replies.

muntquist, it would be great to see your club making planes from the plans and hopefully posting opinions and upgrades so we all benefit.

On part 8 at the mini3d site it shows the control surfaces on a strip of epp.
The .125 carbon tube is 1.75" back from the elevator leading edge.
The length of the tube is the width of your Tee section + at least 1/8" on each side of the Tee + enough length to go at least 3/4 way to the elevator edge. In other words make tube long enough to go into rudders, across Tee, and leave enough room for the elevator not to rub.

The plans at
http://www.slofly.com/mini3d/
are public plans for anyones use.

If you would like to sell the planes or plans a small modification to the shape or dimension would be nice to see or at least post some nice looking ones and videos here!

Making it without the Tee down the middle and using a carbon rod instead gives you aileron a little closer to the fuse which helps in hovering roll control.
I have carbon tubes and T connectors that fit on a .125" rod.
It makes having a full rotating stab with a tube pretty easy to make.
Hopefully there is an easier way that does not require the plastic Tee.

Thanks. Not to remain off topic, but any idea what album/CD it's from? Also sounds like Coltrane. My favorite guys!

Thanks again,

Aha the song is Frandance.

I'm thinking I like Jazz too because I fly to relieve the stresses of a lifetime of programming.

17 sure seems like the magic number! Guess That's what I'll go for on the new one I'm ready to commence with... Hope I can fit 17t/24g on the 20mm I'm playing with. If not, guess it'll have to be the 22.7 that's waiting

Got my kit today. Should get started by the weekend. One slipped in front of it

Alright Gene!

Motor stats:
GB v1.1 kit
26g wire
22.7 stator
17 turns
Wye
2 cell with 8043 draws 4.4 to 4.8 amps (enough to pull out of hover)
3 cell with 7035 draws around 5.8 amps (10 to 12oz thrust)
I have custom prop adapters for the CD motors under brushless parts.
They are also prop savers. Using surgical tubing slices crossways to make a rubber band is cheap and great. Or maybe someone knows a better source of prop saver rubber bands?

Ahhh... 26g... THAT'S EASY!

Forgot to check on some of the other accessories when I ordered, darn.

I've been using a 1/8" wheel collar, drilled and tapped through, with 2x 4-40x3/8 bolts. Don't remember who first suggested it, but sure is better than the servo arms I was trying originally. I'll have to try the surgical tubing. I've been using 2 #10 rubber bands. A #12 or 13 O-ring works well too.
