Dudders Posted November 26, 2023 Share Posted November 26, 2023 Several decades late to the party but I've always liked the lines of this bird and have bought the kit. Any advice on 4 stroke power please? Tried and tested preferably and for me it needn't have much vertical potential. Thanks for any input 👍🏻 Quote Link to comment Share on other sites More sharing options...
Andy Stephenson Posted November 26, 2023 Share Posted November 26, 2023 The power you need will depend on whether it's the traditional foam wing, slab-sided kit or the new Lite version. Quote Link to comment Share on other sites More sharing options...
Kim Taylor Posted November 26, 2023 Share Posted November 26, 2023 (edited) IF it's the 'Lite' version with the built up wing - I built one of these (still have it but converted to electric power) and fitted an ASP61 4/. It flew it very nicely indeed, easily enough for me, although I'm no aero whizz. If it's the original kit with foam wing, then maybe a .70 or more, but the weight will be creeping up if you go much bigger. Kim eta forgot to say, I used 12x6 or 12x8 prop on the .61, sorry, cant remember which. Edited November 26, 2023 by Kim Taylor Quote Link to comment Share on other sites More sharing options...
Dudders Posted November 26, 2023 Author Share Posted November 26, 2023 (edited) It is the 'classic' sheet and veneered foam 🤤 not the laser cut 'lite'. Edited November 26, 2023 by Dudders Quote Link to comment Share on other sites More sharing options...
Masher Posted November 26, 2023 Share Posted November 26, 2023 My 'classic' flies perfectly on a 55AX, one of my favourites Quote Link to comment Share on other sites More sharing options...
Alan Hilton Posted November 26, 2023 Share Posted November 26, 2023 The original gangster 63 was great on an os 61 rf pumper its vertical performance was off the scale .If I did one today I would go for an os 91 surpass. I did modify the model to a tail dragger to accommodate the tuned pipe for the rf pumper 1 1 Quote Link to comment Share on other sites More sharing options...
Nigel R Posted November 26, 2023 Share Posted November 26, 2023 Would be 80 or 90 four stroke for me. Quote Link to comment Share on other sites More sharing options...
Dudders Posted November 27, 2023 Author Share Posted November 27, 2023 (edited) Interestingly my 65AX with muffler weighs 625g whereas 81alpha is 610g I'll go with the four stroke just for the pleasure🤤 Edited November 27, 2023 by Dudders Quote Link to comment Share on other sites More sharing options...
Nigel R Posted November 27, 2023 Share Posted November 27, 2023 81a is a lovely bit of kit. Very economical and reliable runner - (touch wood) I've never had mine cut on me in flight. Just a thought, the Gangster U/C might be quite short for a big four stroke prop, might need a three blade? Quote Link to comment Share on other sites More sharing options...

extra slim Posted November 27, 2023 Share Posted November 27, 2023 A lot I saw fly back in the day, were Webra and HP 61 powered and were very good. No doubt modern 4 strokes are Luverly, but if you want to go all authentic, one of those types of power plants would be good. 3 Quote Link to comment Share on other sites More sharing options...

Dudders Posted December 1, 2023 Author Share Posted December 1, 2023 I think if you were buying then the FA-82 would be the ultimate power to weight four stroke. Quote Link to comment Share on other sites More sharing options...
Flyboy3 Posted December 16, 2023 Share Posted December 16, 2023 Is the gangster lite for electric power only ? Cheers Quote Link to comment Share on other sites More sharing options...

Masher Posted December 17, 2023 Share Posted December 17, 2023 Irvine 53 in mine, excellent match. Unfortunately sold it to the club crash King who promptly smashed it 😪 Quote Link to comment Share on other sites More sharing options...

I can confirm that the Gangster is still impressive 😃 I have a tradditional "heavy" G 63 with OS 55AX and it is one of my favourite models and it does everything nicely!
