That's cool. What was the motivation?

that's pretty interesting. I was only able to find one site on a web search for carbon fiber foam core. a sheet big enough too a geobat would be way out of my price range - almost $400 for a 24x48 sheet of 6mm.
maybe I was looking at the wrong stuff?

This airframe was built by Middle Georgia college aviation department.
They have a 1st class composite school there.
AeroBat Aviation contracted this plane to be built....
Soon it will get a Autopilot.

I guess the motivation for it was to build a plane strong enough for rough handling by people that don't understand the frailty of RC planes.

That's about all I can say about this.
Big things are happening

any suggestion is If can turn this to a geobat or the other way around
looks plausible and should fix the CG problem most of us encounter , not to mention the SciFi factor looks



NTE stands for Not The Enterprise
so as to stay true to the Idea
should you build this use the Registry NTG as in Not The Geobat

I'm hooked I'm building one!, I have printed it out taped all together cut out and cut out a set of templets cues I know my RC buddies will want one next!! I have a question does setting up the control surfaces in delta (elevons) have much of a difference in performance ? I could save on time and hardware going that route but if its not advisable I will stick with the build log method.

Regards Bill

An after thought what does KFM front end mean ? Is that something different than the original plans?

My first one had elevons and I loved it. One less servo. Also my next one will have elevons! The SpiderBat

They actually work better for high alpha and hovering because when you use seperate aileron/ elevator set up, the ailerons are outside the prop wash so you loose aileron authority

We would love to see progress of your build. Feel free to ask questions.

Thanks for that fast reply I did edit my post to include another question about the KFM front end, now wadding through the thread I see that some have added plates on the front on the out side of the fuselages and maybe another center plate on the bottom and plates there too! Is that over kill or for better aerodynamics ?

Some people build with what they have on hand..... many are very different....
The good thing is... if you abide by the CG they all seem to fly good.
This is not a 3D plane or even very aerobatic... but its a great cruiser. Handles wind well... can carry a alot of weight, good camera platform and it's way cool!

The consensus is to do the KF on the bottom for best results. It also stiffens the wing. I found it moves the CG forward as well. maybe 3/4 of an inch.

The canopy Helps keep your brain in check for orientation.... and they are cheap too.

Mark again thanks for the fast reply!
I did go back and find that point where you talked about this add on to the nose. May be a good idea for me as I tend to have dumb thumbs at times and could use extra strength, no 3d crap for me I like Sunday afternoon tooling around and the camera set up sounds like fun! I have already ordered the canopies and some carbon rods and flat stock glue ect. I will post some pictures as I go if that's ok?

Regards Bill

This is my first time using foam as a matter of fact my first foamy period. So I am going to do some self indulgence and post my progress as it happens that way if someone sees something that I'm doing wrong you will lend a helping hand and help me along.
Oh by the way simple is my middle name.

Finally found a use for a life time of Model Airplane News.
Question do you guys peel off the membrane on the pink foam for glueing or just glue to it and not bother it all?

I leave it on, the foam is much stronger with it on. Sometimes I will poke lil holes in the membrane to let glue get down in there. (only at the glue joints)
