I came across the following picture of the Maximilian Schmitt Monoplane on the web somewhere and even though the shelves are overflowing with unbuilt kits, I thought it would make a neat addition to my even more overflowing micro models.

A further web search came up with a few more pictures, but no real specs or plans or three views. And there does not app to be a thread on one here on RCG or other sites.
Maybe not surprising since the key words in this next image seem to be "strange ship" and " freak ship!

Right up my alley! You had me at strange....

Here's another artist's rendition which looks somewhat different from the other one.
Suits me! I'll pick and choose what I like (or rather - what I can do)

IH8VTEC got two kits for a 22" wingspan DLG glider sold here on RCG and I put one together in a couple of days.

22" span of blue foam. Seems super fragile even with the fiber tape support on the underside. I have a really hard time figuring out how to grab/ toss this thing. The AUW is right at 24g using a microVapor Rx and a 30mAh lipo.

I thought I'd "improve" on the stock setup of foam pod with the Rx stuck to the top and the 1mm CF pushrods running on top of the wing.

So.... I used 0.5mm CF pushrods running internal to the boom, a much cleaner setup although I'm having to address issues with the servos binding.

For the pod I used a 4g lightbulb packaging. It looked a lot like a bird's head to me and I couldn't resist. The Rx and lipo attach to a CF square stock CA'ed to the boom and are easily accommodated inside the clamshell pod.

If I ever get it to fly properly, it'll look really nice in the air.

Heres a 4 min video of a 14 minute maiden outing with a couple dozen tosses.
An exercise in frustration

So there are these 3 trees on the edge of the park where we fly…
http://youtu.be/VHFR22l9-fw
I was having fun weaving in and out of the spaces between the trees. They seemed a lot closer than they do in the video.
Funny thing, the flying got a lot worse when the video camera came out. Or maybe the wind came up.
Either way, I need to repair a broken lower wing. But this was just the sort of fun thing the cheap flyzone micro foam bipes are good for.
No regrets.

I am trying out the magnetic building board method on my current build.
The board and a few 1"x3/4" magnets were purchased from A2Z a long time ago and sat there eating dust while I tried out the "pin down" method.

In retrospect, the materials could have been had for much cheaper: use a cookie sheet for the board and buy the smaller 1"x1/4" magnets (and lots of them) from a hardware store.

The main advantage to this method for me was that the magnets being square and stackable would help in keeping my build pieces square.
And there is no pin holes in your wood. Although I'm finding the black dust (ceramic?) on the new magnets to be more annoying.

Also the magnets are really too strong for small bits of balsa in micro builds.

Lego bricks to the rescue! I read about this somewhere and decided to give it a try and like it a lot. Take a few lego brick of whatever size suits you and magnetize them by sticking neodymium magnets into the holes on the bottom.
Other plain blocks can be stacked on top if you need longer verticals.
Take care to stick all the magnets in with the polarities going the same direction on all the bricks.
Magnet sizes that work:
5mm round x 2mm thick for the thin lego bricks
5mm round x 4mm thick for the fatter bricks.
The magnets fit in very snugly and I have not needed to glue them in so far.
That's it! Super easy. I prefer the 3x rectangular bricks with two magnets inserted. The hold is good and strong.

Just press-fit the 5mm magnet discs


Here you see all the magnets and bricks I've tried. I find the 3x2 rectangular lego bricks and the 1/4"x1" regular magnets to suit my needs best


And colorful too

Someone told me I should try placing my postings in a blog rather than adding threads to the forums. I'm not sure what advantage this offers or how the postings will be found by anyone interested, but I thought I'd give it a try by adding my most recent project here.
=+=+=+=+=+=+=
The Rake Sperry monoplane.
I had planned for this to be my first build off of plans, but I ended up getting the short kit to save some time.



To my (non-expert) eyes the wood looks good and the laser cutting is excellent. I specially like that the part numbers are not etched onto the wood but can be read on the accompanied parts map. This makes for less sanding to remove the etching.
This will be my first short kit and I decided to give the magna-board building a try as well.
Also I decided to cover the plans with clear packaging tape instead of my usual wax paper this time and see how that goes.

=+=+=+=+=+=+=
The laser parts in this kit fit very well.
The magna-board is working out so far. But I need more magnets than the few that came with it


=+=+=+=+=+=+=+=

1/4" magnets from Lowes work even better since they are not as strong.

Wow, I can't believe it's been a year since I attempted this conversion!
Just the recap... The idea was to do a quick and dirty D8 using existing parts and pieces: FZ Dr1 fuselage and LG, reshaped rudder, struts and CF from a defunct 4site, and the wing (here's where I went wrong) from a um P51

I fashioned a new wing using 3mm depron tracing on a 3 view drawing plan and gave it some undercamber by rolling over a table edge.

It has more wing area that the p51 wing and worked better:

But maybe it could use some dihedral?

Here's a short video of the D8 maiden

Fokker D8 maiden (0 min 9 sec)


great snap roll to invertged flight right at take off a better pilot would have continued the take off inverted...

Seriously though, this was the fourth attempt.
Notice the left to right oscillation. What causes that?
I had the rudder throws reduced to very small movements with D/R setup.
On one occation when it did stay up for a few seconds (no video) that left to right severe bank continued.
My highly critical eye indicates that something may be wrong

Ideas welcome!

I had a chance to rework the D8 pull-pull system, but no remaiden yet.
The magnets holding the fuse halves together turned out to be a great idea
Just undid the spars holding the wing to the bottom half of the fuselage and opened the model up.
You can't really see the new lines in the attached video. Here's what's new:
  • Replaced thread with 4# fishing line.
  • Replaced heat shrink channels with Teflon tubes.
  • Replaced 90° rudder bellcrank with a bellcrank from um p51.
  • Moved elevator contrl line exit points forward to avoid sharp angles.
  • Added lots of physical down trim to elevator. - maybe too much, we'll see if I have to open her up again.
  • Control surfaces appear to be centering OK. The rudder centering is a little sluggish but sure is improved.
Magnets to the rescue...


New location and angle for the elevator control line

I guess this counts as a Dr1 mod?
FZ Fokker Dr1 to Fokker D8 conversion

This will be a longish post with some details.

The fuselage, elevator and landing gear are from the Fz Dr1.
Super Solvent was used to strip the red paint off of the foam and it worked very well.




I scalled plans for the D8 with the idea of cutting a wing out of 2mm depron.
