(Here is a thread from the Netherlands. Guy has a 1/5 Pica waco)
Sorry for the english, bud I fly an electric Pica Waco.
I have to be fair, it has done only one flight up to now.
I fly it with a ROXXY BL OUTRUNNER 5065/09 (45a continious, 50a max)
and with 6s2p LIO-Ion battery pack (22v, 4400mah, 50c max)
it further has Cyclon Pilot 100 controller (100a continious, 120a max)
it swings a Topflite TOPQ5220 - 18 x 8
The first flight was a nice, I had lift-off in les then 10 meters and a 45deg. climb without any problems. Landings was also fine.
By the way, it ways in at about 6,5kilogram.
