    That is SO okay Walts,  the more the merrier, as you say.

    So, is It that the luck may change for me as well

    Well, it has to be some more of these around? Feel free to show your Typhoon here. Another pic of mine:

    Isn´t Unitracts retracts adjustable? The Spitfire units would otherwise do the job.

    That´s a nice one Walts! I like that you added the inner doors, I kind of wish that I would have added those on mine. What was the setup of yours?

    Thanks for the kudos Walts, it is very nice to get some compliments. Sorry to hear about you maiden-flight, I hope you get more success after the rebuild. On to the questions; The panel lines is actually made with a dull lead pencil (kind of engraving), if done right it makes a nice shallow line that is more defined during the weathering. The nose is as per the original and I had to make an inset box to clear the carb and intake. I measured the C of G at the root next to the fuse with the wheels retracted, wich actually makes quite a difference, the C of G with the wheels extended is 105 mm, a weight-transfer of 5 mm! With the C of G at 110 mm it is not overly sensitive on the elevator and gets a nice sit in the landing configuration. Regarding the weight, I made the fin hollowed and the rudder built up from 1,5 mm balsa, all in the name of lightness. And I still ended up 600 g heavier than Tony´s. That man builds LIGHT! Oh, and by the way, the only thing remaining is to put on the exhausts.

    I have made the maiden on my Nijhuis Tiffie now, and what an airplane! I was a little concerned about the weight. The total weight ended at 4150 grammes! A "bit" more than stated in the article. After I mailed Tony I was told that his prototype actually weighed 3550 g balanced. The wing loading on my is 100g/dm2 wich I consider quite normal on this type of model. I have a Saito 80 with a 14x8 prop on it, wich gives it the necessary urge, to say the least. I placed the C of G at 110 mm with the wheels retracted and that is a very good starting point. It is a very pleasing model to fly and I didn´t have to make any trim changes at all! By the way, I covered it with SIlver-film and painted it with Prymol-primer and waterbased Vallejo Airbrush-colours and used 2-pack matt clearcoat to protect it. All markings are painted. I will use it in our national class "sportscale" here in Sweden on the 28-29 of June and see how it fares there. Here is a few pics of it: It would be nice to see all the other ready built Typhoons here as well.

    No the retract angle is a bit more like 95 degree. I found it out the hard way

    Would be nice to own one of those.....

    I have built the Typhoon, and I can´t get it nowhere near the weight described in the article. I have used the lightest balsawood that I could practically use and the CNC pack from SLEC. I covered it in the same way as in the article, with the exception that I used Warbird colours instead of Flair Spectrum. Considering that I don´t fancy electric setups for scale, I installed a Saito 82 wich is a lightweight four-stroke engine. When I balanced it with the wheels retracted and aimed at a C of G of 100 mm I had to use almost 800 grammes of lead! (possibly only 600 if I make a really heavy spinner adapter). An empty weight of 3400 g + 800 g of lead = 4200 g, almost a kilo more! The (standard size) elevator and throttle servos are mounted just behind the firewall, and the rudder servo behind the 280cc fuel-tank. Have I made something very wrong or what? I haven´t added any sort of heavy scale details over what was described in the article and photos therein. Would be very happy if Tony responded and let me know how he think it will fly? and how this could be? I have been building scale-models for the last 15 years, so I am not a beginner at this game. I also would like to say that this is no criticism against Tony´s design per-se, but more of a wondering. Because if you, as John said earlier, spends a lot of time and money on this model, and is lead to believe that it could be a grass-friendly machine with little weight, ends up with a One-engine-heavy, it leads you to wonder why you didn´t spend the time and money on a design that does what you´re told it will do! If the Hurricane ends up as heavy as this one i much rather build a Vaillancourt one! Then I know what i have to expect.

    I´m in again....
  19. Michael Graff
    Well i´m definitely in this one.

    I´m in !

    Here is my list; #1 Douglas Dauntless, 180 cm span for glow or petrol. Everybody needs one.... #2 Bolton-Paul Defiant, 170-180 cm span for glow or brushless. Extremely rare bird. #3 Northrop Gamma, big one, maybe 2,2 meter span for glow or petrol (or very expensive ´leccy setup). As a welcome step away from the usual stuff. And please no more small airplanes under 160 cm span. Haven´t we seen to many already? And please design them for both glow and electric setups. I, for one don´t want the complicated `leccy stuff. And no twins and whatnot´s, how many do you think will actually build ém? I am almost finished with the Typhoon by the way, with a four stroke of course.

    Try some Alkylate petrol (I don´t know if you have it in Britain) It doesn´t smell half as bad as regular car-stuff.
  24. Michael Graff
    An old Dauntless kit with fibreglass fuselage (230cm span) and a lovely Skyshark Avenger.
  25. Michael Graff
    The wheels are to be replaced with some Robart 90mm´s, they are on backorder unfortunately.
