Whatever, gotime. In general, the new flyer needs more than many seconds in the air, and that implies a LMR power system. Electric is fine, but carries with a considerable weight overhead, and light is always better. For a very few ounces the Norvel 061 can carry the plane to a respectable altitude, albeit a bit noisy and slimy.

It is a Hobby-Lobby Elegant, That's it in my avatar. Good review of it over on that other RC Forum that specializes in electrics.
AUW 74oz, 110" or 107" depending on what you read, i didn't measure
750 sq/in wing area, 14oz/sq ft wing loading
Mega 30/3 direct drive
Jeti gold ESC
UBec
Graupner Cam 10x6 folding prop, pulls 37A measured
10x2400
4 HS81 in the wings
2 HS60 in the tail
Motocalc predicts 960 ft/min climb at 28 degrees. I think I am climbing out at around 40, 30 second run gets me way up there. I get 4-6 runs per pack.
I just flew the maiden on it this past weekend and the weather has not been thermal weather and I am still getting 6 minute flights per run, total flight length 30 min.
It sure seems to be a floater even at that wing loading.
