RE: New F18 70mm size
Yes it will hand launch if you remove the gear and the missles, etc.
I would HIGHLY recommend that you make the first flight off of tarmac, so you get the trims right and you get used to flying the plane.
Also run the engine for a while before you start trying hand launches to wring it out.
For your first hand launch have someone else throw the plane for you.
Bring it up to full power and have them take a running step or two forward and toss the plane at a 10-20 degree angle. like throwing a javelin at a shallower angle.
It doesn't need a lot to get airborn but it is safer to start it out with a bit of extra speed.
I'm considering adding a bungee launch hook to mine...
