Ah well guess I'm pants at carving foam. I may try a balsa one at a later date.

johnfireball,
     Excellent job on the build, hope it flies half as well as it looks. Wish you the best for the test flight. Freedom Flyer

Hi all,
       I finally got to test fly my model, just 2 short flights until I broke the undercarriage and I have now beefed it up a bit to handle John landings. It flew very well but needs slight right rudder trim to track straight  . The bigger motor is just the job (thanks Keith, maybe a bit overpowered), it gets airborne on half throttle in two feet, I am using an 850mah 2s lipo as it balanced just right with this fitted. I also added some scale features (the wing mounted oil tank), finished the rigging and dirtied it up a bit. Cant wait to fly it again. Sorry no flying vid (too busy trying to fly). My freewheeling engine works a treat.

Happy Days:
Well done John! :clap:  :clap:
 So where did you fly it? Do you live in a big house? 8)  You’ll have to get one of your kids to film it flying, it would be good to se it in the air. :D

If you’ll allow me, I’d just mention a quick word about “beefing up” parts of a plane.
“Beefing up” is normally a metaphor for unintentionally “adding weight.”
Adding weight to a plane increases its wing loading. :arrow:
Increasing wing loading increases the stall speed :arrow:
Increased stall speed equals higher landing speed :arrow:
Higher landing speed often results in damaged airframe,… and so on, and so on.

A wise old man once told me that, “Building an aeroplane, is a question of compromise.” :!:
