Thanks Rog, good advice there! I didnt realise that rubber gloves let through the nasties - lesson learned.

Lots done recently the T tail is on & I've started on the wing joiner slots in the fuzz. By a massive stroke of luck one wing with the fuzz is a nice fit across my modelling room & as I have a horse shoe type set of building boards around three sides of the room it was a doddle jigging up the wing & fuselage so I could mark the blade slot on the root. One issue this epoxy fuzz doesn't have the usual ply infill inside on the wing root? Do I need to cut one & epoxy it in? It seems quite sturdy as it is. Another thing that I'm very tempted to do is fit it out with 6s electric power, I already have the motor & lipo packs so am considering a 6s setup with 500 kv motor & a 16x10 folding prop with a 42mm spinner.
It would mean not flying at the peak but it's a little large for up there & I could then fly it with a dolly undercart from my Power flying field in Frome as well as aero towing on weekends away :)

Martin,
I would certainly recommend adding a ply former if there is nothing substantial there already as the wing root areas will take all the flying loads and also probably ensure that your wing joiner dihedral angle remains constant!

We discussed this at the aerotow if you remember Pete.
When I drilled through for the slots it was only epoxy glass that came out.
No plywood shavings at all. I remember all the old grp fuzzes had plywood reinforcement in the cuffs. A lot more work needs doing then it seems.

Anyone know why Bucks composites have nothing in stock? All they're resins are marked temporarily out of stock & have been for a couple of weeks.
They do have a water based resin in stock, anyone used it yet?
Looks to be OK & says for ding resistant covering to wings etc,
Hopefuly be alot less messy to.

Martin,
It might be worth giving them a call to see what is actually available.
I have found them very helpful & their phone times today are 1-3pm ish.

Not available at those times for phoning so I've taken a chance on it.
I'm sure it's very suitable & not being epoxy based probably a lot safer on health issues.
Still need to wear gloves etc & the process is a little more involved & for full
hardness is achieved only after four weeks. Luckily I'm in no great rush as this model won't be ready till next Season.
