  1. Hi Ben,

    I've built an 1/8th Spitfire from an old Aerotech Int kit and i must say the kit itself was rubbish. I won it at a club do around 15 years ago, i now understand why the model shop donated it......

    The build process was very similar to the link above with lots of foam parts. You would think that would make life easier but not one of the foam bits fit properly, and i had to get a new set of foam wings made because all the cores were different sizes so couldn't be joined without an 1/8" jump between the sections.... Also some of the pre-cut parts were wrong and had to be remade.

    That said, the model itself flys lovely and with everything sheeted / veneered foam its a nice base to glass and paint.

    I truly hope your kit is better than mine, maybe mine was a friday afternoon job. But with some time and effort it should build into a nice flying plane.

  2. Well a few months has gone by but heres my refurbed Alienator.

    I used a hardwood spar in place of the balsa one and extended it into the fuselage, so in effect it became a full span spruce spar, and lined all the straight edges with balsa to square up. Also changed the hatch so the front section is removable and rear section is fixed with a tongue and magnet.

    Its covered in lightweight glass cloth and poly c, then sprayed with b and q emulsion before a final few coats of sprayed poly c for fuel proofing.

    I maidened it last weekend and it surprised me the roll rate you can get. Fast doesn't describe it. That said it need a fair chuck to hand launch because of the weight i added in glassing etc, but its a great addition to the hanger.

  3. Hi Steve,

    In my spit i used a 15 way mini D connector. I just used one pin per wire, as i had 5 connections to make. Works a treat and never had any problems with it.

    I can't see a problem with having common +ve or -ve, but for the sake of a couple of extra pins i prefered the extra redundancy. I would rather lose one servo rather than all if one soldered joint gave way. Although as Bob said you could always make the pins into a common rail for extra redundancy.

  4. For anyone interested in the windbag, theres a guy on Ebay thats started making kits / selling built models. £85 for kit or £115 built, or £150 with engine and servos. Seems a bit steep to me but i guess the kite isn't cheap.

    Usual disclaimer, i have nothing to do with this guy except contemplating whether to give him some money wink

    With their staggeringly poor time keeping record, Fly,Maybe!

    I was waiting for this one, they are my employer.........

    A couple of other nicknames i have heard:

    Air Lingus - Air Fungus

    Jet 2 - Tech 2

    Ryanair - Conair

    Easyjet - Squeezy jet

  6. Never heard of that so just done a search and only came up with a couple of threads and no pictures but, it seems that the Square one had foam wings and maybe a grp fuselage. This one is fully built up from balsa and looks like spruce longerons on the fuselage.

    Edit: Looks like the Square One was around 52", so a bit smaller that the one i have.

    On a different note, does anyone know the way to tell an engine size on an engine with no markings?  In the trainer there is an engine with Irvine on the exhaust, but no size or any other markings on the engine itself.  Well as far as i can see on either side above the mounting lugs.

  7. I've been given a couple of planes and was wondering if anyone knows what they may be......

    First is a 3 channel trainer of some sort. Fully built up, it has a removable tail held on with leccy bands and wingspan of 78", trike undercarriage without a steerable nose.

    Second we have a fokker DR1. smiley

    73" span, so 1/4 scale. This needs a bit of work to get it airworthy again so i could do with finding out what kit it was built from so i can gather some info on it. There are a few 1/4 scale kits about of the DR1, so hopefully someone will have some knowledge about the differences. Its definately built for strength, and also has a removable tailplane although i guess this could have been added by whoever built it.  Also the top 2 wings are permanently joined, but again i'm not sure if that was by design or done by the builder. 

    DR1 1

    DR1 2

    DR1 3

    DR1 4

    DR1 5

    Any help gratefully accepted.

  8. No probs Stuey. I did experiment with thinning the poly c with just water, and although it seemed to thin ok i wasn't too sure on the coverage so decided to use it neat so i knew how good the coat was.

    I used ready mixed screenwash to thin the emulsion i used with excellent results, although i didn't try water for it. I can't see why the screenwash couldn't be used on other water based products with equal success.

  9. Well i'm sure you build faster than me. Took about 10 months to get the Spit finished. But its all worth it in the end, i enjoy the building almost as much as the flying.

    Thanks, its always the little touches that make it different but also take the time, the cannons, radiators, tailwheel, etc.
