Hello Glen, I'm back.
I have a friend who wanted me to build something using his busted PZ Vapor for parts. I immediately thought of a UM UFO. The prototype I started with is a 12" diameter with 6mm FFF for the body and 3mm readiboard for the KFm step.
The prototype seems to be very stable so it went from being a prototype to finished model in one flight.
6mm FFF circle @ 12" diameter
3mm $Tree semi-circle @ 12" diameter
Champ/Vapor ESC/Rx brick
Champ/Vapor CF control rods
Flyzone Playmate landing gear
450mah 3.7v lipo
I also added some pictures of the 12" UFO on my blog page at
for anyone wanting to build something similar.
Here's the video
