Peter Rake 67" Bristol F2b build

G'day all,

with the Pfalz done and dusted it is time to get started on my favourite WWI bird, the Biff. with Maltone having successfully built and flown the beautiful prototype last year i figured i would have a crack myself. my first 2 builds were pretty basic, so the plan is to add a lot more detail to this build such as a cockpit, rib stitching, lacing ect. i will sort of be cheating i know, but i will be following Pat's build process pretty much word for word, apart from being in my own jumbled order . Imitation is the sincerest form of flattery as they say, so i would be mad not too!
the kit arrived a few days back from Manzano's, and bloody nice it is too, fast service, great packaging, beautiful wood, and cutting, oh and there is lots of it!
i decided to warm up by making the tail plane and fin, gave me a chance to have another go at laminating which i quite enjoy. made up some forms for both, stripped down a pile of balsa and got started, they both came out quite well, i framed them up but have not separated the individual components yet as i still have to surface sand them down to the 1/4'' profile, and add the slight airfoil to each.
figured i would then have a bit of a go at the fuselage, i opened up the slots a bit so as the formers would fit, laminated the forward and tail sections ensuring they were left and right handed. i framed up the first one over the plan, and then flipped it and built the second straight over the top of the first. that is about it for this week, time to go back to work and ponder the finer details of the build, oh and a power system, if i recall Vintage 1 designed a scale prop for Pat's build, i like the sound of that, just have to sort out a motor /battery combo to make it feasible. also want to sort out a theme aircraft, am thinking of either Kingsford-Smith's, or Hudson- Fyshe, both of which were in an Aussie F2b squadron in Palestine.....mmm!
as usual any tips, and balls ups you see don't be shy in pointing them out

Cheers
Craig

Good to see another one on the board Craig I'll keep an eye and learn when you do something better! It is an intimidating build (sort of) but take it slowly and all will be well. Only advice from mine is to keep the tail weight minimal. When I get back to my second, simpler version, I'm tempted to use Litespan on the rear end parts - I hated adding lots of weight up front.

Cheers Pat, i am tempted to go with litespan everywhere, or do you think she is a bit to big for that, and maybe it's not robust enough considering the wings are designed to be disassembled for transport?

I am reassured that Hammered has used Litespan (or equiv) for his bigger models - sure it is a bit fragile but as long as it sitting on top of rose-bush prunings in the car, it should be OK

Too true, from memory he has used tissue for the current Albi, and that's no peanut scale

Cheers mate

Craig,
The stuff Hammerd is using on the DVa is actually a form of Litespan type material - Airspan if you buy it by trade name. It's the same basic stuff, but has to be sealed to make it airtight. IIRC, it's some form of polyester tissue.

Looking forward to your build.

Pete

Cheers all, I won't be a quick build but it will be completed, I am sort of lucky in that I work away week on week off, so like Pat I am sort of retired but only every 2nd week

Cheers

I like Airspan and Litespan. If I am painting I like Airspan and I have a ton of the white stuff.

FWIW, if you cover using Pete's method, ie, applying the Balsaloc to the material, then the Balsaloc does a good job of sealing it.

Not sure I would use it on a plane that large, but, no reason it won't work. Doped tissue was used for a long time on big stuff.

Joe - to the best of my knowledge, Airspan is the same stuff as Litespan but without the coating - ie. it is unsealed and needs dope or similar.

I think I will be using Polyspan when I do one of these beasties. Sure adds a lot of rigidity to an airframe.

Pat is right, Airspan and Litespan are the same material with Litespan being sealed from the factory. Airspan can be easily sealed with a coal of Krylon clear.

I think I will wait until I am back at home so I can download some nice hi-res images of the shuttleworth Biff. That way I can see what will give me the best match texture wise.

Cheers
