That's good that you can do that with him.
The motor in my cub is electric. I have moved to electric because it is clean and all you do is change your LI-PO battery over.

Don't bin them as I will buy them off you if you are not going to use them.

How does it go Nick? Is that the ESM Spitfire MkIX?

John, I´m not going to bin them. At the first time I would like to modify them. The biggest problem of their size is in their depth. I can´t hide them under the cowl. But now I´m waiting for fibreglass cowl, so I must wait.

Hi Prekin,
That's right, I have reduced the BT wing to 73" to fit the ESM fuse. That will be good practice to build the 83" some day

Where are you getting the composite cowl from? Do they also do full composite fuse?

Thanks Prekin,
I was thinking maybe you found a source for BT Spit composite fuse in Europe

If you don´t need the composite fuse now, I´m going to make fibreglass fuse.

Nick, at the first time I wanted to buy ESM fuselage and build only the wing. But when I was thinking about it I reach the result that is easier to by all ESM kit and remake it or built this Spitfire on my own.
I remade ESM Dauntless and La-7 and found out, that the biggest problem was a scale cockpit and place for air tank. Other problem is the wing. I want to make wing from two halfs.
Here are some shots of my Dauntless and La-7 now La-5FN I saw that you did something similar with CMP Bf-109.

Jiri,
I've admired your craftsmanship on the SBD and La-7. I have done similar ARF make-overs on the CMP 109, the Kyosho Spit 90 and the ESM Bearcat (pics to follow). On the last 2 I rebuilt the wings and covered with Fliteskin.

I got the ESM 73" Spit wing second hand with a broken wing from a rough landing. I repaired it but didn't like at all its flying / stall performance. After some investigation I found excessive wing root incidence (2.5 degrees), little to no washout and a very strange airfoil (scale semi-symmetrical at root but thick symmetrical at the tip).
So I gave up on the stock ESM wing and decided to build a nice scale BT wing, cover with Fliteskin and match it to the fuse.

Kyo Spit, not scale geometry but very light so good platform for experimentation:
- Built proper wing fillet
- Stripped covering and glassed / fliteskin'd
- Sliding canopy and some cockpit features

Don't want to hijack this thread with my ramblings, I'll send you a PM

I see, you made nice wear out around the Spitfire´s wing root. How did you make it?
I will wait for PM.

And the wear out? I see, you made a scratch a paint on the root. Is that only some silver paint on the coat?

Oh right, you mean the wing walk weathering.

I spread sea salt over the primed wing, then paint the camouflage colours, then scratch the salt crystals off and you get the random paint peel effect

Yeach weathering is the right word. So you mixed salt and water and spread it on the wing. I must try it. I´ve just tried on the piece of desk but never on the airplane. I have to say, that the result looks pretty good.

I also wet sand some of the paint off the panel lines and rivets, and the light gray primer reveals the surface details:
