martin collins 1 Posted November 4, 2018 Share Posted November 4, 2018 I wonder if anyone here can help me with the balance point on the the Bryant Magister, i have got it roughly set up at 1/3 of the wing depth where the raised join is between centre section and the outer panels of the full size. Many thanks for any help given............ Edited By martin collins 1 on 04/11/2018 20:04:56 Quote Link to comment Share on other sites More sharing options...
Paul Gregg Posted October 29, 2020 Share Posted October 29, 2020 Hi Martin I'm new here. I'm rebuilding a 67in Magister and I'm not sure whether it's as yours -Denis Bryant or Dave Platt design. I hope by now you've had a satisfactory reply to your Cof G conundrum and that all has been well with that. When I have confirmation of my Magisters Plan origins I will obtain a plan as I'm going to need one-that's for sure! It'd be good to learn how you've got on.

Andy Gates Posted January 6, 2022 Share Posted January 6, 2022 Hi Guys, How did you get on with your machines? I have just picked up a Dave Platt plan and have had it enlarged by 120% to get it to around 80" wingspan. I am changing the rib profile as the full size was built with Clark YH section rather than the almost symmetrical section shown on the plan. I also plan to halve the weight of the original which I have read was around 10lbs, aiming at 4.5lbs and electric powered. Quote Link to comment Share on other sites More sharing options...
John Stainforth Posted January 6, 2022 Share Posted January 6, 2022 Andy, 4.5 lbs for an 80" span model is an incredibly ambitious target. If you can achieve that it will be something of a record and you will have an amazing soarer! Quote Link to comment Share on other sites More sharing options...

Ivan Pettigrew designs very light large models, in the back pages of the current RCME there is pictures of Mike Roach's 120" Lincoln bomber built from his plans and it only weighs 7lb ready to fly.

Andy Gates Posted January 7, 2022 Share Posted January 7, 2022 (edited) I have a very wing weary Ivan Pettigrew Chipmunk which is now 17 years old. My wood selection was not as good as it could have been, and she weighs 5lbs at 75" wingspan. It flies on 3S lipos and I can get 10 mins of flight from a 2700mAH pack. It gets used for training as it is large so easy to see, light weight so it can fly very slowly and has no vicious handling traits. Please don't think this is necessarily a gentle flier, sure it lands slowly but it can take off in less than 5 yards in still air, perform loops from level flight but I am still happy to fly her in 20mph winds with gusts at 25mph. I belong to a group of flyers who fly IP models in the UK & Europe, BIMBO's (British Ivan Model Builders Organisation), as does Mike. We have been visited by Ivan in the past during one of our get togethers in the south of England. True John, 4.5lbs is still slightly optimistic but with care, hopefully achievable. I have my own website which shows some of the IP planes I have built, they are all still with me and flyable.

Eric Robson Posted January 8, 2022 Share Posted January 8, 2022 Very interesting web site Andy, I particularly liked the Fairey Gordon, I have always been an advocate of light build aeroplanes, although I do have some heavier models that fly better in the strong winds we get too many of up in the North East.

Eric Robson Posted January 8, 2022 Share Posted January 8, 2022 Getting back to topic, Martin as no one has mentioned the C of G, I have a Duncan Hutson plan of a 56" span Magister . I can measure it and scale up if that will help. Cheers Eric. Quote Link to comment Share on other sites More sharing options...
John Timmis Posted January 8, 2022 Share Posted January 8, 2022 Just looked at the Dennis Bryant plan. The CG is 3 1/4"" behind the root leading edge. Quote Link to comment Share on other sites More sharing options...
Andy Gates Posted January 8, 2022 Share Posted January 8, 2022 95mm or 3 3/4" on the David Platt plan at 120%. That is 80mm or 3 3/16" at 100% Quote Link to comment Share on other sites More sharing options...
Andy Gates Posted January 8, 2022 Share Posted January 8, 2022 EB Look under Commercial plans - Magister. I may do a thread on here a bit later. Eric Thanks, as you may have gathered the Gordon is very special to me. Certainly flies differently as befits the original. Quote Link to comment Share on other sites More sharing options...

Andy yes I have seen that you have started but the photos are too small for me to make anything out, a thread on here would be more informative I think so please do.

Andy Gates Posted January 8, 2022 Share Posted January 8, 2022 EB try them again. I have cleaned up a couple of the images and if you click them (all apart from the plan ones) you will now get images twice the size. Hope it helps you. 1 Quote Link to comment Share on other sites More sharing options...
