RE: Viper Jet 2M Pointers/ tips.
Haha, maybe its better not to weight the model indeed.
Can remember when I was building my UL, I did everything to make it light (due to my indoor flying history).
When finished, the UL was simply to light, yes that can happen to! ;-)
Anyway, the Viper gained 400 gram (14oz) more after painting. Not to bad I think.
