Scaling the Mini Tensor to twice it's size, produces a big badass 44" Tensor, made from FFF or 6mm depron. Yes, that's an ordinary coke can, for size comparison. I'm definitely going to build one of these! Empty weigt is about 12 Oz / 340 gram. AUW is 19-23 Oz (540-650 gram). Power it with a 100-200 Watt low kV brushless. This monster likes big props.
Today we made a flying model of the battle bus from fortnite! It ended up being more of a blimp rather than a hot air balloon but propane regulators at that size would be hard to find, nevermind...
