If you want to glass it with say .75 oz cloth and wbpu or if you want to paint it then EPS. If you like the factory colors and want it a bit tougher then the EPO is the way to go. I glassed mine and painted it so I used the EPS version. Sanded off all the original paint and filled the panel lines to 95% before glassing. Callie graphics for the vinyl decals.

When it all came together , I ended up using a bit of everything , different parts of the airframe got a different glue . Gorilla glue and epoxy are good for the fuse halves but I use medium ca to tack them in place as they cure , stab blocks got 5 min epoxy along with the fin and tanks . Wing got 5 min epoxy , I even tried hot glue , not so good as the heat causes the EPO to puff up

I saw one that had the wing put together with epoxy separate in the air during a high G pull up. While the joint could have used more epoxy it was found that the epoxy did not stick that well to the EPO. I think that the Gorilla glue works good on just about everything but you have to be careful not to get too much on. CA should work well.

Here is some info from RCU:

I have started to see EPO in other products. I have a glider called the Hawk that is made of it. However the retailers seem to be confused as they are listing it as EPP." EPO is definitely not EPP. It looks similar to Elapor but it has a greasy feel to it.

What kinds of glue work on EPO?
"Regular CA?" Yes but needs kicker.
"Epoxy?" No
"Gorilla Glue?" Yes
"White and yellow glues?" No
"Others?" GWS Glue or Polyurethane glues

"Can we use fillers with EPO to get smoother finishes? What kind?" Fillers are not needed and possibly would not stick well.

"What kind of sanding considerations? Will it sand?" Yes it sands well, but the kits need very little sanding. The surface finish is almost as good as that on the latest GWS EPS kits.

"Any special considerations for paint? Water based?" Solvent based? You can use any type of paint that will stick. Both water and solvent based will work but some paints require a primer.

"Can I apply Monokote or similar coverings to it?" I have not tried to and see no reason to.

"A common repair method with Elapor is to heat it with hot water to expand it after a hard bump. Will EPO work the same way?" I have not needed to repair yet.

One thing I do when I epoxy two foam halves together is take a phillps head screwdriver and make 'rivit holes' on BOTH mating surfaces before gluing. Makes sure they get a little bit of shmoxy in the holes when spreading the goop and it will be almost impossible to separate.

jjr2001...great list of tips, covers the brunt of questions...

Good luck with the 4s set up , I tried to make it work and the motor gave up on the second flight , I had run it in a boat at 70amps but the heat build up in the stock fan was a killer.

6S 4900mah 25C Rhino. I fly for 3 or 4 minutes and still have 50% capacity upon landing. Battery is about in the center of the battery area. I still have about 1.5 inches in the front and about 1.5" inch in the back as far as I remember when I made up my positioning blocks.

HET 9305 fan and 600-37-2 motor for a whopping 54 amps at about 1250 watts nominal. Files nice but not supersonic. LOL

Thrust not measured but it flies good and lands good so I am happy with that.
No need for super speed on this one.

It's an 8s setup on a Neumotor 1415/1.5y and should be around 80 amps and 2,800 watts.
