Posts made past 02:30PM 12/30/24 won't be on the new site!

We are in the final stages of resolving the issues with the forums move to the new location. After talking with tech support, the only solution was to send him a copy of all the images. This will take time - but we know the fix SO it's only a matter of time now.

Thanks again for your patience,

    Yak ??

    Hate to show my ignorance, but what are the differences between Steadfast and Checkmate?? I believe one has a 2000, and the other a 2800.....what were the orginal engines?? What mods have been done to them? Thanks.......just trying to educate myself a little.

    I can't speak too much about Czech Mate, but Steadfast is a new Yak 3U built in Romania. Originally the prototype used an Ash-82 I believe. They built very few radial Yak 3's. Yes it has an R-2000.

      The Yak 3U was a development of the inline powered Yak 3.

      CzechMate is a Yak 11 which is a trainer. It had two seats and a 750 hp ASh-21. CMate has been very modified including R-2800, Skyraider prop, new cockpit layout complete with street signs, inner gear doors, taller tail, lengthened fuselage, and I think they replaced the wood pieces with aluminum.

        Czech Mate was getting a new leg last weekend but should make Reno.

          I've worked on 5 Yak-11's and derivitives and there is no wood in them. Fabric, yes, wood - no.

            man if the prototype of the new Yak-3U radials had the Ash-82 man that would make a fast racer, the Ash-82 in standard trim has about 1500hp, but if it was the Ash-82F they could be run at take off power (1700hp) all day that would be fast, ive seen the Lavochkin La-9 in action and that is a FAST airplane..... and they have an Ash-82Fn which is 1800hp at take off

              If you saw and LA-7 fly your a bit older than I am and I'm no spring chicken. From what I know not one LA-7 was flyable after 1947

                  La-9, not La-7.

                  Having seen it fly a few times in the UK during the few months it was based there, a VERY spectacular and rare machine with a unique sound.
