Raven Racing Series

[philf]

If you're thinking of the whole airframe a metre should be more than enough....not sure how much weight it adds?

Hokey Doke. It adds weight but also stiffens it up, Maybe I'll just cover the leading edge. That is meant to be the best option.. If that is ok in the rules?

I though that was the rule Andy, leading edge only if you do laminate. Maybe we should check with Brucey Whiting.

[Brucey]

You called! Actually was thinking more Brucey Ecclestone, but it would be wrong to fancy your own daughter!
Lamination is optional, full, leading edge or non at all.

It's looking like it might be OK next weekend, fancy the inaugural Newport Pagnell Grand Prix?

[Brucey]

I still need too get a raven, and I'll be in the peak district next weekend. Hopefully have the vent finished so I can take it with me

Appear that wing may have laminar flow to around 75 mm at 20 m.s-1 and transition to fully turbulent flow at 150 mm..  I'm thinking laminate the first 75 mm, and the lip'll act as a turbulator..

hmm.. OTOH I'm startin to take it all too seriously  :laugh:

Anyway laminate the first 75 mm sounds good to me. xtra weight is all forward and good for stiffness...

I was just going to stick some fibre tape over the leading edge... that's my hi-tech approach

HeHe .. my Flyingwings Falcon has  tape.. It just looks so cak. Mind you I'll prob succeed in making this racer look cak too. Think I'll try putting a film of POR under the Lam to help it stick. That foam is funny stuff and dont seem to like stuff sticking to it virgin. I used Evostick impact on the Falcon... whicjh looks like bogeys :)

Unfortunately Raven Racer will have to carry the extra weight of my OSD.. else what's the point of making the darn thing  :laugh:

Raven Racer ordered !

Nice one Andy. The lam will stick fine to virgin foam, I used to use a spray adhesive first, but not bothered with the vent I'm currently building and its fine.
Just make sure you put the lam adhesive side down, otherwise it makes a mess of your iron...

Well when I was out with Neil his lam was bubbling up. What was going on there then?

Wow.. Thanks indeed for that profound tip  mate. ;D 
What? not allowed to borrow the iron any more now then?  ...Same here (solarfilm in my case!) :laugh: :laugh:

I think it was the temperature of my iron Andy, Caroline won't let me use her posh iron anymore so I bought a Turnigy laminating iron and was too conservative with the temperature, I've gone over it again with a hotter setting and it seems fine.

I had to use a layer of por to stick tape to my Falcon... making me think I need to lam the leading edges now.  Ok, laminating virgin here, what sort do I need, and do I need that 3m spray adhesive... which stuff ?

[philf]

Rob from Flyingwings will sell you some....it will stick perfectly well without any spray adhesive.

I've got 200m of the stuff Wayne, PM me your address and I'll send you a few metres.
