Yeah, mine is 3mm for that piece. Had to slice inside each flute associated with the radius, like the main fuselage, to get it to work. No probs, smooth curves, still strong.

Does anyone have a picture of the underside front fuselage please?
I would like to see how you all mount/attach the Rx and battery and keep it in place.

Here's my insides. Just a piece of scrap 5mm balsa I had. On the top side there are a couple of little gussets at each former but nothing full on. I just used velcro to hold everything in place, plus an elastic loop for the battery.
Sean, that Ag Wagon is a mean piece of kit, love the camo. I've got an E-star Ag Tractor kit sitting under my desk waiting it's turn. Always loved crop dusters. The performance coupled with looks only a mother could love make them the greatest underdogs.

Great stuff JMSR!!
Your contruction is spot on!
How do you find the CA glueing on the corro?......I tried it a few times with little success!......maybe it's just the type corro we have here?!

Thanx for the words on the AgWagon. Took a year to scratch from a .40 size plan.

Hi Sean I hope JMSR does not mind me answering, but I beleive he uses Loctite 406 CA with 770 primer. The trick is the 770 as it prepares the plastic chemically with special magic . Here's some info:

LOCTITE 770 100ml
LOCTITE 770 is used to make polyolefin and other low energy surfaces suitable for bonding with Loctite cyanoacrylate adhesives. On such treated surfaces the cured performance of Loctite cyanoacrylate adhesives is generally similar to that
described in the TDS for the relevant adhesive. It is only recommended for difficult to bond substrates which include polyethylene, polypropylene, polytetrafluoroethylene (PTFE) and thermoplastic rubber materials.

By the way my MIG building has ground to a halt for the simple reason I can't get away for even an hour during a weekday to get more material Bruddy frustrating it is!
Cheers.

Ok!
Thanks for the info argo-2!
I will ask around and see whether the 770 is available locally and give it another try!

The Loctite is the go all right. I've made a couple of correx planes before this one using just 406 and it works well enough on its own but no where near as good as with the 770. It also cuts down the bloom effect. You do have to be accurate though because the correx will rip before the glue that's for sure!

Start with as per the drawing, shown on the fuzz. I have moved it back about 8mm to be able to throw the plane around nicely. But the position of the wing is important. But again, go heavy in the nose then lose some as you go.

Saw your comment about a manual during the build, sorry, but not gona have time for that,. ..........unless someone comes along just to scribe and not build!

Thanks Sean, I stupidly left it off the fuselage

Has anyone measured it from the LE of the inside of the wing nearest the Fuselage?

Just about to weigh her up in a bit (battery inc)....

I move my battery around for different results but If I remember rightly it's about the same as what Sean is saying. CG at the rear edge of the main spar for acrobatics and dog fighting. CG at the front edge of the main spar joiner for low passes and smooth cruising.
Measurements from the inside face of the LE fuselage slot are 76mm to 86mm. From the tip of the LE where it meets the fuselage it's 81mm to 91mm.
