David,

A 22 mm 950 KV motor would need at least a 10" prop on 3 cells (<20 amps) to get moving
A 22 mm 2450 would probably do well with a 5x5 prop (<25 amps on 3 cells).

If the boat gets sticky on the snow, spray PAM vegetable spray on the bottom... or go to 16 cells (not!). 

Neat project. 3D projects are always colourful.

Basic construction is done. Painting and decorations are in progress.

Here it is with its big brother.

I didn't think it would work but I tried my 2212 980iv on 4S with a 4.75 x 4.75 2 blade prop... and nope... wouldn't budge on icy snow.

Will have to wait for the 2212 2450kv and 3-blade 5x4 prop to be delivered.

The aero boat calls for a 2212 2200kv motor so I wasn't too surprised.

The adapter rings were perfect.

Two of the attachments points were perfect, the other two were no so perfect. That's because someone glued them in backwards.

Anyway, two small drill holes solved that.

I just love it when they're working in the right direction.  How did the EDF Adapter Ring work out... and the little EDF Attachment points, etc.?

Fans and speed controls are all wired up, and working in the right direction.

Interesting.

I have a kit for a this Airboat.  Maybe I'll get to it in the summer.

Some may notice that, side by side, some parts of the fuselage are different shades.  I didn't notice this until I started putting parts together... and it's a bummer.  It doesn't bother Michael because he's going to paint.  But it drives me crazy.  Really excellent prints, but different colours.  I kept thinking about this until I realized I'd run into this before with a DC-6 I printed and built (but haven't flown 'cause I'm too afraid... but this summer for sure... honest).  In the image below you'll see striping.  This drove me bonkers and I could not find a solution to it.  Out of the 4 nacelles on the plane, it only happened this badly on one.  The colour difference is because of the direction the nozzle lays down filament.  Left to right is a different reflective shade than right to left.  In this nacelle the print head kept changing direction.  On the Learjet the direction stayed the same for the whole piece, but because of the way the parts  had to be placed on the bed for printing, the head would travel in one direction for one part, and the opposite direction for another part.  Put the parts together and the light reflects a different colour.  I didn't even think to look for this while printing.  It's not so noticeable (or at all) on the white Learjet, so I never knew to check... not that there's anything I could about it.

I'd like to see this issue as an option in the slicer.  Print clockwise or counter-clockwise to ensure colour consistency.  Sometimes you can orient a part on the bed so that it does affect direction, but many times a part is already established in a specific position for best printing.  All in all... rats.

I'll report back if I can see the colour difference 50 feet away while flying... I imagine not.

Lots of snow outside.

Flaps installed but not set up to function. Getting these to work would require a more significant amount of modification, so Dave and I have decided to try to fly these planes without flaps. The flaps have been screwed in place so as not to move. If landings end up being too fast, this issue may be revisited.

Basic wing, tail and fuselage assembly/construction is done.

David,

You can now join us when the water gets soft at Toogood pond.
