I'm leaning that way Woody. Ordered a 1/7th full body pilot from Century Jets for it.

Two panels left and the top of the fuse will be skinned. I think I will do the front bottom and then the FG nose cone while I'm making a canopy mold. I'm removing much of the interior crutch as I go.
I think the top is the hardest skinning part.

Subbed !

That thing is really large.................are you sure you will still be able to hand launch it safely?

I would bet he's planning on bungee launch...

Hey J, I seem to remember a hand launch of a certain B-26 down at SEFF a coupla' years back

Woody

It has to be hand launched its one of Hans requirements

Wow... Interesting. I'm sure it can be done, and if anyone can build it right for the job it is JM, but from someone who's been caught by a prop during a hand launch I don't think I'd want to be throwing this one with power on.

Power off OK, but I'd want to hit the gym and polish the "guns" a bit before giving that a shot

OK, here's the deal. Thrust to weight. Not sure which system I'll use yet but leaning to the Scorpion 3026. Have to check specs on it again but it hauls my 8 lb birds with authority.
As to hand launch, my 141% F-16 hand launches just fine ( by the pilot no less!)with about 500-600 watts. Can't remember what it weighs but I'm guessing around 5 lbs. This size is 200%.
MIT KID said his big EF weighed up to 17 lbs in testing and they hand launched it. But there is a difference. His is a twin TRACTOR power system. With the pusher you have no prop blast over the controls and it needs some speed for good control on the launch.
I'm hoping to keep this around 8 lbs, hopefully less, we'll see.
Right now the fuse weighs 22 oz. The wings are 5 oz each. Stabs are 1.3 oz each. So I think we are on track so far.
But as I said, we'll see.
Did I mention I have a gold medal in the Olympics for javelin throwing?

Sorry didn't mean to de-rail your thread,was thinking about the prop at the back.

Amos

LOL and here I was going to say "don't forget to stretch first" but didn't want to start something
I'm a Noob to this stuff but I don't see hand lunching a plane like this as a problem. It would be like throwing one of them blow up alligators around with wings on it.... O man now I may have started something..... flying alligators everywhere

A nice indented hand hold might make things a bit better for you to hand launch.

Anyway I'm going to sit here with my popcorn and learn me some
Looking Grate J

On the EF I put a hand hold about a foot aft of the CG, made it easier to handle and put some oomph behind the launch. http://static.rcgroups.net/forums/at...3-IMG_0506.jpg

But as J said, it'll be a bit trickier with a pusher. If you can come in sub 10 lbs this thing will be beyond awesome. Looking sweet already.

Thanks guys

It all depends on the AUW. Bungee is NOT out of the equation but hopefully it will be hand launch. Could have left this a simple profile and it would have hand launched easily. But as usual, OC took over and I'm going full blown scale on it.
It might be Hans' flier when he's here but I have to look at it all the time.

Adam,
I will be placing a hand grip on the bottom. The 141% F-16 has sandpaper patches on the bottom, my hand just barely fits for hand launch. This bottom is too wide for that.

Have the top done skinning. I'm glad! Working on a batt box that will be in the nose for a 4s-5000 if I go the Scorpion route.
Last of the build pics until Monday, have some family business this weekend.

Forgot to post this pic of the 141% F-16 and the big one. The big one gets an add'l 11" nose cone too!!!!

Hans had better have muscles in his spit to be able to launch that monster. Hell! I have a problem with my Bixler!
