I am salivating already . that is one sexy looking bird !!!! I'll keep an eye on this ! I was promising myself not to get MORE platforms but this one is definitely a wallet tickler !!!!

When they start selling, will somebody with more money than me please mod one with a turbine and post a video of it flying.

we'll call it a furbine (foamie turbine)

Man that was fast. Iran to China in a hart beat.

Keep dreaming.
Highly swept, high aspect, foam wings, are not suitable for super go fast RC turbine planes.
Too much flex, twist, and flutter. Maybe a tiny little turbine just to push it around
but not much point in it.

You mean post a video of it melting

What the heck!! BEVRC is selling to Iran and not us first

I know your worst fears Ian . It would be good to see the bottom of this beast. It would be pointless to design the plane that can carry 2Ah or more and being unable to launch it.

That problem can be overcome. Search for the various Multiplex Funjet and Twinjet vids.

No, it's not the same.
That is, by comparison a very low aspect swept wing (like some full scale jets). I was very
specific about the wording of the problem. High aspect (long and thin), highly swept wings,
have a problem going very fast. People have been trying to overcome it for decades with slope
gliders yet they still twist and flutter. It's due to the effects of spanwise flow,
which usually requires building some washout into the airfoil (lower
angle of attack at the tips than root). Washout causes the
wing to twist when you go very fast, and any wing that wants to
twist, will usually flutter at some speed. Also, it's much harder to reinforce the
whole wing, when you can't run spars from tip to tip through the
center, due to the sweep.

If we were talking a composite construction, then could probably pull it off, but this is EPO.

Ya, you got it (although you probably meant 20Ah). It looks like from the latest vid, that
he was able to hold and launch it from near the CG, but also looked sort of like he was
doing it by his finger tips so I'd very much like to see what there is to hold onto down there.

The X8 is not that big, I mean the wings look thick. for its size, also you can always put some extra rods, on which point I am getting nostalgic for EPP/GOOP magic combo, uh.
Anyway I am fine flying electric.

Lots of solar cells would fit on that!!!!!!

I may have just quit cutting foam........
