Hey Glenn.  That glass cloth needs a bit of smoothing  ;D

Keep up the good work guys (except Michael who's already finished).  I can hear the ice melting as we speak... well... maybe not.  But soon!

Very cute.  A pocket Rocket!

Are you going to dress it up with a cowl?

That's a pretty nice Cessna, but flight times leave a little to be desired.

And that's a busy runway!!!  I'd be worried about hitting someone and damaging my plane!   :o

Wing measured and aligned, leading edge dowels drilled, wing hold down screw drilled and tapped, fin and elevator test fitted in place.

Next: motor and ailerons.... then covering.

Ed,

great to hear from you.

re: the "Only 500w/lb?" 

You know that was written by Andy who is a disciplined but conservative full-size Cessna 150 pilot. He usually expresses power in terms of "number of turns".   ;D

At @Frank v B's standard 500 watts/lb and a 1200 lb carriage, I'm betting on a 1600S battery pack at 100 amps! 8)

Congrats Frank!

Only 500w/lb?

  Very nice!
  I really like the decals as well.
  Here is my 415. a few pictures outside today. Everything is glassed except the top side of Ailerons and Flaps. I will continue when I get back from vacation. In the meantime. the epoxy can fully cure.

Installed the two aileron servos in the wing (HXT 500's) and the elevator servo in the fuse (Hitec HS 55).  Glued them in place with epoxy.  That's commitment!

The Kevlar is barely visible at the front and back end of the hatch (top of fuse).  Stabilizer and fin done and sanded.

- Sanding completed
- added a plywood triangle to spread the load for the wing bolt.  Note the grain is chord-wise.
- built the hatch.  Will add magnets later.
- second thought on the strength.  Added a strand of Kevlar at the firewall (360 degrees around the fuse) and the wing hold-down at the fuselage. Attached it with 20 minute epoxy* and wrapped it in wax paper so it will dry flat. Added two rubber bands to press it flat.  Note the colours for Andy's sake.  The original design had a fuselage doubler which I omitted.

* Bruce- ran out of 5 minute epoxy. ;)
