    New build project advice

    in All Things Model Flying

    Posted

    I have seen in build threads before, scale modelers dont cover thier models with film, instead they glass cloth them and use second skin and then paint.
    This is a new science to me could anyone advise and tell me how to fuel proof this as well, I thought the finishing resin would be enough fuel proofing.
     
     
    Craig have a read Poly-c (one day I must update that document )

    Craig it will probably be ok, but the plans do show the scarf join on the three side sheets in staggered positions (as it should be so the stress is not in one point)
     

     
    In his build article TN states
     
    Start by making up fuselage sides from sheets of 4.5mm (3/16” balsa You will have to splice sheets of 900mm (36” balsa to make these sides. Note the ‘cut’ outline is slightly larger than the fuselage profile. This takes into account the curvature of the fuselage and the trimming required to level the triangle flush with the tops of the fuselage formers.
     
    I'm sure a butt joint with a doubler should be ok

    Poly C and Foam

    in Foam models

    Posted

    "Apparantly poly C and ronseal diamond are exactly the same stuff."
     
    Sorry but NOPE
     
    Poly-C is manufactured by Ronseal for sealing and hardening wood used on Gyms & Shopping Mall wooden floors (tested with heavy fork lift trucks carry weights), it's trade name is Floorseal XL.
     
    Ronseal Diamond is NOT the same, Floorseal XL bonds and laminates at molecular level, Diamond does not, it just seals, and is sold to joe public as it contains none of the ingrediants (apart from the H2o portion) of Floorseal XL due to what can be sold in shops in the EEC.
     
    A simple way to cover foam (blue or white) is to use tissue (ask any shoe shop for freebies), and apply just like paint with a brush. The first coat will hold te tissue down and in place, the second coat will make it very tough, apply a 3rd coat and its a job done.

    Hi Guys.
     
    I second your words on the plastic mouldings Graham, and for the price
    charged a little quality control wouldn't have gone amiss.

    It really does annoy me, and fills me full of dread over ordering the Halifax mouldings

    Jim I feel your pain with the cowl, spats and canopy. The cowl and spats are by far the worse moldings I've ever come across, no markings, either scale or cutting.

    I've just cut my canopy, I built the cockpit sides, and then put the canopy over and then you can see where it needs to be cut, but cut 1/4" oversize, easier to cut more than have to put it back





     

    A MISSED OPPORTUNITY

    No matter how good the kit, (or plan) builders (US) are a very small minority in this day and age. No matter how good the kits are (Skyshark in the USA is an excellent example of great cad drawn plans, excellent laser cut parts, and top quality parts, with impressive written (and downloadable) manuals with pictures) that the number of people purchasing them is dwindling. Skyshark have stopped making kits, why ? the numbers were just not there, plus the cost of quality parts in the box (laser cut, manuals etc) made the price higher than a chinese ARFs.....

    Sad as it is, this is now the future

    Must admit the build article in the mag sucks, ok if you've done lots of building but for a new comer to building, Nope. You have to study, study, study then study the plans again and again, and then look to this thread (and others) to grasp the details. Not the worse though, have seen much worse!!!
     
    As for the lanc, good luck, if you need any scale info (articles,  mag reprints, books etc) on the lanc let me know. I did pm Supermario about the Halifax as again I have lots and lots of info (mostly in .pdf) and most are now out of print.
     
    But anyway back to the Topic.
     
    Moldings arrived today (URGH), looks like a lot of work ahead.
    Started inner panels today
