David Davis Posted January 4, 2022 Share Posted January 4, 2022 Once upon a time OS produced the OS52 fourstroke. Now they produce the OS FS 56 Alpha. Did they ever produce a fourstroke engine with a cubic capacity between these two or is my memory slipping? Quote Link to comment Share on other sites More sharing options...

Martin Harris - Moderator Posted January 4, 2022 Share Posted January 4, 2022 Perhaps you’re thinking of the Thunder Tiger 54 FS? Quote Link to comment Share on other sites More sharing options...

That's what I used in La Coupe Des Barons last year. The reason I asked the question is that for the 2021 Coupe Des Barons the maximum size fourstroke engine permissible was a 56, the smallest new OS fourstroke then produced. This year they seem to have gone back to a 52 which makes my Thunder Tiger ineligible. No matter I have at least two OS FS 52s, a Magnum 52 and two OS 48 Surpasses. Perhaps I should build a Lancaster! ? Edited January 4, 2022 by David Davis Quote Link to comment Share on other sites More sharing options...
Nigel R Posted January 4, 2022 Share Posted January 4, 2022 The 56-a has a lot of go for its size. Perhaps it was deemed 'unfair advantage'? Quote Link to comment Share on other sites More sharing options...
Paul De Tourtoulon Posted January 4, 2022 Share Posted January 4, 2022 An Os .40 is more than enough, don't forget that is was built for an OS .25 2 stroke unless yours is armed with steel and concrete,,, Quote Link to comment Share on other sites More sharing options...
Nigel R Posted January 4, 2022 Share Posted January 4, 2022 A .25 two stroke powered baron ain't going to win DD the pylon race round, methinks. Quote Link to comment Share on other sites More sharing options...

It has all of the above, plus racing and apparently, freestyle random crashing! Anyway, I'm enjoying you and DD talking up here. I may start a side-hustle taking bets! ?

I actually won the fourstroke class last year with a Thunder Tiger 54. 52 minutes ago, Paul De Tourtoulon said: Pylon racing ? So not like the original coupe de Barons, spot landing, limbo, bursting balloons and breaking sticks, . The flying rounds are as follows: caisse baguettes, breaking one-metre high balsawood sticks stuck into the ground; a pylon race; chasse renard in which a trainer slowly pulls a crepe paper streamer around and you have to cut it with your propeller and the dreaded limbo. The 2017 video is the best in my opinion: https://www.youtube.com/watch?v=IwWg0Ad5cKs&t=839s I believe that Paul has an HP VT fourstroke in his model. You won't win the event with any fourstroke. The engine of choice is the OS 35 AX but many of the electric powered Barons are very fast too. PS. I am not going to compete with a twostroke or an electric motor because I have established a reputation as a fourstroke devoté besides since 2019 I have given a prize to the leading fourstroke pilot, a big box of balsawood!

Paul De Tourtoulon Posted January 4, 2022 Share Posted January 4, 2022 Our last 'coupe de Barons" the baguettes were polystyrene and I won that and the limbo with my 21 VT na na na na na,,,,, Quote Link to comment Share on other sites More sharing options...
David Davis Posted January 4, 2022 Author Share Posted January 4, 2022 I expect it was just a club event. Not the real Coupe Des Barons. 1 Quote Link to comment Share on other sites More sharing options...

Don Fry Posted January 31, 2022 Share Posted January 31, 2022 I was trained by a Frenchman with a star, after my mum got me a Saturday job in his restaurant. She was a fine cook. And he had a first plate, (starter), chicken sausage with marmalade d’orange amére. That’s chicken sausage grilled with Saville orange marmalade, and then braised, with a fancy salad, nuts and bits.
