Here is my first attempt at the ULTRON 300, this is a 55% scale, I made some modifications on the wings to have a more wing like shape.

What a beauty!!
I'm going to build this. BUT I want it bigger since I have build many plains in that size. How big do you think I should make it to fit a 390W motor on 4s in it? It is 90 gram

Had some very good flights with my Ultron Sat-Tuesday! Weather was perfect and she flew like a dream.
Was pushing the limit a bit and took a bit of a hard landing Squashed the bottom fuse where the battery starts and both sides of the fuselage just infront of F2. Bit of reinforcement and epoxy later and she's back! Went out to fly and one of the aileron servo's seized! Gah!! Luckily had a spare so she should be ready to go soon.

Mitja, she really is a great flyer! Thanks for the plans

Do anybody have a motor recommendation for a 250-300 gr plane? I have one, but it's not powerful enough for my plane...

Has anyone used a gyro on their ultron? I have a tarot zyx-s that I am thinking about using on it. I saw one video on you tube. The plane looked really stable while prop hanging.

My maiden when well till a piece a tape on the front of one ail came loose .It banked to one side in 8 mph winds and went down a bit so i hit the rudder to level her out and landed it in one piece . Iam going to have to use glue when i stick the tape on next so this wont happen again. It flys where you point it and rolls were fast and crisp but i did not get a chance to ring it out anymore after the tape came loose. joe
