My Feedback: (3)
Depending on your total elevator travel but you can safely start with 3% down elevator. Also note that if you have reduced flap speed (this is what i did) dont forget to set the elevator mix speed at the same speed rate to avoid pitching when you switch to full flaps.
Take off Flap (1st notch) doesn't need compensation ( at least on mine...)
Hope this helps.

here you go, I found the cockpit image file (printed it it 13x18cm and cut by hand)

Also got k102 as I was planning for almost a year now.. much lighter, smaller...
Compared to my k80(same size as k100g2)
advancement in 7 years is amazing!
old is 26% longer 15% wider 40% heavier!!
and new one has 25% more thrust
test benched today ..... well not bench but ok

Hi there
I have read a lot of this nice plane and a friend and me decided to go for it
A few days ago I finished the build.
I must say that I like the quality of this kit very much. The wood parts are more or less ok, I only reinforced the thread positions by adding wood and made a new electronic tray out aircraft ply wood.
I'd like to credit Dr. Tom for his very nice cockpit and for providing the file to print it.
I designed a few parts to make my life easier...recessed MR30F holder for elevator servo and front wheel cover with integrated battery tray.
My setup is as follows
TX: Powerbox Core
RX: Powerbox Mercury
Lights: Unilight Kit for MB339 2m
Turbine: Xicoy X120
Thrust tube: Akatec (238gr), specialy made to move the X120 as far as possible to the front
Fuelbag: Norbert Trost 3L, usable capacity approx 2.2L
Dry weight: 8795gr (without drop tanks)
COG: 142mm
Looking forward fpr the maiden flight :-)
