Allo everyone !

I just started to build a mini Simple Cub with the electronics of UMX Radian .

I use yellow Adams ready board ( not the water proof ) and since it's yellow on one side only , I glue the yellow paper on the white side .
When it's done drying under weight so it doesn't warp , I put packing tape over it . I glue that paper with Elmers stick and all the foam is glued with Foam-tac ( I love that stuff ).
Other than the UMX Radian's electronics, I bought two 1.25" mini Lite Wheels and Sport Cub Props and sinners .
Feel free to leave a comment ...
Will be posting as the work progress .
Thank you !

That's awesome! What happened to the radian? The umx radian is one of my favorite planes!
I crashed it too many times LOL! That was the first plane I flew and I had no simulator practice ... It's the tail that was the problem and I couldn't repair it anymore ( after 5 times ). It was very fun to fly ,but it's a bit fast ... The ground comes fast LOL !
Thanks dude !

Landing gear is done. It's 1mm piano wire tied and ca glued. The problem is that it weights 105 grams and the UMX Radian flying weight was 55 grams ( they say 43 gr ) . I wonder if that is not too much for that motor and prop . The prop is a 5x2.75 ( 130x70 ) .

Please tell me what you think. Is it too heavy ?

It looks fantastic! The only way to find out weather its to heavy is to fly it!

ALL DONE !!! Need to program the transmitter and try it . The rudder struts are made of a carbon rod ( in the UMX Radian's wing ) and the wing struts are made of rubber bands barely under tension so it's streight . Fake motor is balsa . Total weight is 135 grams ( the xk800 flying weing is 110 grams ).
The CG is spot on . I will give feedbacks after the maiden :)
