This looks very Nice hooks. Enough and good choice of color too.
Is the tail reinforcement a Clip-On type? I think , now I don't have to add the CF rod I was planning to place inside vertical stabilizer. This reinforcement should do the trick.

YES please when and how much $, i have been waiting for this before i build mine

Oh my God, it so nice Chris !
Thanks Hooks ! But they appear to be like we wear hat on the head and sosks in the feets !
For rest of the body there is nothing, am I missing something ?

Hooks, is it possible to develop two complete halves which covers all the foam body at almost all places, to provide additional strength ?

Remember, there's a large carbon fiber rod going down the middle of the fuselage to the tail. I think it's pretty solid as it is.

Two complete halves will defeat the purpose of foam body. Instead you might buy a FG fuselage it self if some one makes it.

Wow! And my Skywalker just arrived at the post office. ;)

Looking forward to this nice add-on.

Hi all
@ Chris I'm glad you like it.

I'm not sure factory will ever make the reinforcement for the Skywalker. :-( and if they will produce it, it would be in same material as the PVC canopy. Not just what I expected.

Making this reinforcement in FG or Kevlar takes some work and afford. So if I'm not going to make it in numbers it would probably cost around 60-80 UDS. (NO one would pay 60 USD for a little painted FG or Kevlar).

I sold a few to costumers for 35 $. (but I can't produce these covers and at the same time have a little profit) sorry.

@Rena Yes I made a complete Mold from the EPS foam (first version) but I'm not going to make any full FG copy ;-)

You can make it your self feel free to ask any Questions.

Hooks these are beautiful upgrades, but price is the issue for me, I will add carbon spar in rudder post and wrap with nylon fabric then coat with WSPU,

Mark I think it's a great way to modify the bird.

I'm looking on the possibilities to make the belly pan from Vacuum moulding in 2mm ABS. This should cut the price.

Hi Hooks !
EPS is certainly not very good foam and that is for such a big airframe Skywalker.
How much it will cost in Elpar ?

EPS:
This foam is easy to cut, fairly easy to sand, fairly rigid, fairly brittle (cracks easily) and not very durable. If you press your fingernail into it, it will leave a permanent crease. If you hold a very small piece over a match, it will just collapse and dissappear. Regular CA glue will melt this foam, as will some types of spray adhesives and spray paints.


EPP (Elpar):
EPP is flexible foam that is used as a packing material for delicate electronic parts. It is also used in the bumpers of some automobiles. It is a rubbery material that is light in weight, yet very durable.

EPP is available in 1.3# and 1.9# densities. EPP is used in the modeling world for combat gliders that need a high degree of durability. Since EPP is not a rigid foam, most all EPP gliders use fiberglass, carbon fiber, or spruce spars for stiffness.
