Steven Butler Posted June 15, 2011 Share Posted June 15, 2011 HiI have just ventured into the world of biplanes with a nice flair pup. Obviously it needs a 4 stroke and the flair website recommends a 50 - 60 size. I do however have a lovely laser 70 sitting on the bench. Do you guys think this would be a suitable choice or a little too much for the airframe. Advice gratefully receivedSteve Quote Link to comment Share on other sites More sharing options...
ken anderson. Posted June 15, 2011 Share Posted June 15, 2011 the L70 will be ok...fit a large prop and use the throttle...... ken anderson ne...1. Quote Link to comment Share on other sites More sharing options...
fly boy3 Posted June 15, 2011 Share Posted June 15, 2011 Hi Steve. It must be a four stroke LoL., They fly well on a SC52 f/s, but a 70 Laser would be a great combination. Just take Ken's advice and you will have a beautiful flier. Cheers Quote Link to comment Share on other sites More sharing options...
oldSmithy Posted June 15, 2011 Share Posted June 15, 2011 Hi Steve I would definitely use the lazer and probably go for as large a prop as pos with not a huge amount of pitch. I see the lazer weighs in roughly 100 grm over an sc52 but I'm sure that could be dealt with in the placing of the radio. CheersStew Quote Link to comment Share on other sites More sharing options...
Steven Butler Posted June 15, 2011 Author Share Posted June 15, 2011 Thanks for the replies. Looks like the laser has a home. It is such a great engine I was really hoping it would go into the pup ok. All the bestSteve Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted June 15, 2011 Share Posted June 15, 2011 Yes, use the Laser - I had a 70 some many years back, and even now, in my leccy days, still wish I hadn't sold it - not the most powerful of the Lasers, by any means, but a lovely bit of metal nonetheless.

Cheers Stew The extra weight will actually be helpful - most Pups are flying round with half a church roof under the cowl BEB Quote Link to comment Share on other sites More sharing options...
Bob..... Posted June 15, 2011 Share Posted June 15, 2011 i had a asp65fs in mine and needed very little lead in the nose. Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted June 15, 2011 Share Posted June 15, 2011 ASP 52fs in the front of mine. No lead. But a big 6v RX pack right at the front end. Quote Link to comment Share on other sites More sharing options...

oldSmithy Posted June 16, 2011 Share Posted June 16, 2011 Ahaa, so it could even take a 91fs perhaps.?? and dispense with the lead all together. Hmm sounds like a plan! and get the prop more scale like. Might not fit into the cowl? Stew Quote Link to comment Share on other sites More sharing options...

stu knowles Posted October 2, 2011 Share Posted October 2, 2011 OS 50 two stroke, Flair in cowl silencer, large prop. 2.1 ./ 6v batt in the tank bay. Quiet, no cowl extension, no lead One of my fave aeroplanes, try also with the Flair vintage floats .stu k Quote Link to comment Share on other sites More sharing options...
G-JIMG Posted September 6, 2017 Share Posted September 6, 2017 6 years on I've got the same question. Flair recommend a 40-60 4 Stroke, would the RCV60-SP fit in the cowling and be man enough? What size prop would be correct for scale? Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted September 6, 2017 Share Posted September 6, 2017 If the Puppeteer were a scale Pup, then the prop would be about 1/3 of the wingspan - Pup 8.08 span with a 2.55M prop which is 1/3.16 of the span. So you are looking at 18-20" props. I can't help with the Flair cowl size and fit, but it might help if you posted the dimensions of your engine.

Jon H Posted September 6, 2017 Share Posted September 6, 2017 it will be more than man enough power wise but the firewall will need to move back significantly. Not that it is difficult to do. You will also need to baffle the lower cowl to stop the engine overheating. Nice model though, i was taught to fly on a flair pup Quote Link to comment Share on other sites More sharing options...
G-JIMG Posted September 6, 2017 Share Posted September 6, 2017 Bob, Thanks for the response. According to RCV the 60-SP will turn a 16x12 prop, not quite scale but close enough. Jim. Quote Link to comment Share on other sites More sharing options...
G-JIMG Posted September 6, 2017 Share Posted September 6, 2017 Thanks Jon. You're right about the cooling, I have a 120-SP in a Corsair that I made a bespoke baffle for. I also modified the cowl to increase the outflow (and make it look more scale). Sounds like I need to buy the kit Jim. Quote Link to comment Share on other sites More sharing options...

Lindsay Todd Posted September 6, 2017 Share Posted September 6, 2017 I think we have all called the Puppeteer a Pup, and of course you are quite correct its a bit of a cartoon scale in truth. I actually always thought it was much closer in proportion to the Sopwith Strutter and could be easily adapted with the additional centre strut, moving the cockpit forward and adding the rear gunner as well. Would make a great little project actually if I ever come across a kit. Great flying model on anything from 52 to 70 4stroke. Personally I would go for the 70 size for the bonus useable added weight in the right place. Linds Quote Link to comment Share on other sites More sharing options...
Giuseppe Saroli Posted September 6, 2017 Share Posted September 6, 2017 L T there is a kit going on the bmfa classified for for £100 plus £10 post I got mine from flair 6 weeks ago for £170 and i am going to put in a sc 56 Nightmare to connect the trotle linkage do Quote Link to comment Share on other sites More sharing options...
John Bisset Posted September 6, 2017 Share Posted September 6, 2017 What size motor, ESC, and battery would folk recommend for an electric conversion of the Puppeteer? Quote Link to comment Share on other sites More sharing options...
Andrew Hogg Posted September 6, 2017 Share Posted September 6, 2017 I Have a Saito 65 in mine, had to modify cowl a little and make an exit for hot air, but plenty of power and no lead needed. The Mag has a saito 56 and is about 15 years old. Quote Link to comment Share on other sites More sharing options...
