Video of seawind electric maiden flight takeoff... 9 sec clip of an electric seawind conversion on it's maiden flight . The URL is http://www.youtube.com/watch?v=VWn3JVCmI1g .This is powered by an axi 4130/16 ,3 blade master airscrew 12x8 , 2 packs of 4s1p evo 3700 mah wired in series (8s1p),castle creations phoenix 85hv esc , No extensive testing but some quick approx. numbers using extrema charger wattmeter and great planes tach 8000+rpm,1.3 h.p. , 42amp full throttle.Weight is approx9 lbs 3 ounces,approx 110 wattpounds(I'll be weighing it on some digitals soon and will post accurate numbers later)Test flight conditions -18 C,wind 30+kph(-30 with windchill-try that with gas).With half flaps on it took about 10 meters to get airborne and despite the wind it flew extremely well with plenty of power and speed .It cruised easily on just over 1/3 throttle.After 2 mins of flight The batteries used just under 300 mah each.It would be easy to fly in high wind conditions if it was warmer ,as this was it's maiden flight I kept it short.When the wind dies down I'll post some better video as well as pics.I'll be posting some pics of the setup including shots of tach and wattmeter soon.It feels like it has the power to haul a set of retracts around easily as well,I'm sure once I test a few different props I'll be able to get even better performance ,not that it's lacking.
It should take off on water on 3/4 throttle,like it does on snow,when the temps go above 0 again I'll try it out,frozen water rudders are no fun.

.I'll pull the cowl off and get a few shots of the motor (AXI) and mount (hyperion) as well as the "hidden"canopy latch system,nothing is visible and you can take the 
)through the adjacent pulley and goes through the firewall to the next pulley mounted on the former under the access hatch.(you'll note the line guard blocking the view of the cable ,it's made from a piece of steel edging found in a wooden ruler and formed to go around the pulley and attaches to the motor mount)From here it heads down through the pylon and is looped through another pulley at the base of the same former.The pulleys come from Home Depot ,they are replacement pulleys that keep sliding screen doors in their tracks .I used fly line because thats what I had handy,it's very strong ,made for use in water,light,and it floats.I will be using rc boating control rod exit covers for all wiring and canopy release cable through the firewall.The boot that the release cable runs through will be packed with white grease or something similar to keep water out,the motor wires silicone.
