Capt Kremen Posted April 26, 2021 Share Posted April 26, 2021 How long is your piece of string? Seriously, there are endless possibilities and probably as many recommendations from those that have completed their 'B'. Availability - Probably something like Mr Foss's 'WOT4' or 'UNO Wot' 4 Ch version. These are well known, fly well and straightforward to build or acquire in ARTF format. Additionally, these models are so well known that at least one 'ex-spurt' in your club will have flown them and knows their capabilities, not to mention limitations. Would suggest a straightforward simple model that can easily be repaired should you get a manoeuvre slightly wrong involving terra firma! Remember BMFA have online videos demonstrating the 'B' and there are numerous articles, books etc. that describe the 'how to ...' as well. Good luck!

Don Fry Posted April 26, 2021 Share Posted April 26, 2021 Wot 4, perfect with your Irvine 53, get a kit, take patterns of the parts, then when you wreck it, and you will, it can be rebuilt, so it ends up as Tiggers broom, only the rudder is original. Tool for a job, no love. Point easily forgotten, The B is not perfection. If you look up, for instance, a stall turn in aerobatic schedules, vertical climb, stall, aircraft swaps ends on its own axis. Difficult to do consistantly. The B allows for the rudder to perform the turn, so it drops out in what looks like a U turn. Much easier. Quote Link to comment Share on other sites More sharing options...
kc Posted April 26, 2021 Share Posted April 26, 2021 One of our forum members has written a book on aerobatics - Model Aircraft Precision Aerobatics by Peter Jenkins available on Amazon now. Should be helpful in gaining a B so worth reading. I think he also does training sessions for aerobatics too ( North Essex based I think ) Quote Link to comment Share on other sites More sharing options...
Dickw Posted April 26, 2021 Share Posted April 26, 2021 Have a good look at the BMFA's B test video here https://achievements.bmfa.uk/videos It shows the sort of standard you should be aiming for and also illustrates that the flying is not the only part of the test.

Ron Gray Posted April 26, 2021 Share Posted April 26, 2021 I'm sure you will find it helpful, it really is a good book for all types of flying ability not just for those who want to do F3A. Quote Link to comment Share on other sites More sharing options...
Andy Stephenson Posted April 26, 2021 Share Posted April 26, 2021 Some years ago I took my B test with an Acrowot it didn't recover from spins consistently because I had the CG a long way back so it was just luck it came out OK on the day. There are better models, when I first flew my Sebart Angel and went through the B test manoeuvres it almost seemed like cheating it was so easy.

Ron Gray Posted April 26, 2021 Share Posted April 26, 2021 Peter Miller’s Peggy Sue 2, spot on for the B plus a real all weather, ‘go to’, ‘plane. An easy build and rugged as old boots! Quote Link to comment Share on other sites More sharing options...
andy paterson Posted April 26, 2021 Author Share Posted April 26, 2021 One I'm looking at the moment is 48" Miss Sizzles from RCM&E July 2020 ,it's an aerobatic model electric power. Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted April 26, 2021 Share Posted April 26, 2021 I suspect that the reluctance to spin often encountered with certain models may be to do with the limited movement of the rudder advised in typical instruction books. I normally ignore any advice to set, for example, 15mm movement and set the maximum deflection to align with the angle of the edge of the elevator "V". With a reasonable C of G, it's rare to find a model which will genuinely refuse to spin. Assuming a model is strong/powerful enough to perform an outside loop, there are very few models incapable of flying the B test - it's more important to be thoroughly familiar with performing the manoeuvres with whatever you're flying. I haven't witnessed it but I'm fairly sure that successful tests have been flown with 3 channel models. Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted April 26, 2021 Share Posted April 26, 2021 I don't understand why someone who feels they are capable of passing a B test, asking what models best to do it with. I am assuming candidates can do the required elements, if so then it's answered itself. The one you do them with. Quote Link to comment Share on other sites More sharing options...
andy paterson Posted April 26, 2021 Author Share Posted April 26, 2021 Fair play John Stone but not knowing how accurate the flying has to be and I can only find one BMFA B cert video online maybe you could point in the right direction please .

Frank Skilbeck Posted April 26, 2021 Share Posted April 26, 2021 I did mine with a Wots Wot biplane, but just about any sports hack, e.g. Wot 4, Acrowot, Riot would fit the bill, a modern aerobatic model would be like cheating ? Quote Link to comment Share on other sites More sharing options...
Chris Walby Posted April 26, 2021 Share Posted April 26, 2021 IMHO as long as the model will preform the routine then it will be acceptable, one point made when I did mine was the examiners would consider the capabilities of the model. If you turn up with a very capable 3D/pattern ship model that rolls upon its axis then expect a tougher time than something else as they expect you to demonstrate corrective inputs (as per the guidance notes). I had a choice of a BH Speed Air or a E-flite Carbon Yak and used the Speed Air, because I could demonstrate to the examiners my level of skill and control, not which one looks the best or is the easiest to fly.

Peter Jenkins Posted April 26, 2021 Share Posted April 26, 2021 Chris, I have to disagree that if you turn up with a pattern ship the Examiner should expect you to fly to a higher standard. That is a common misconception even by some Examiners. Nowhere in the documentation does it state that. It's like requiring rolls to be carried out with the model being rolled away from the pilot - that is not called for in the Guidance Notes. The one thing that is specified is that the stall turn must be away from the crowd line or display line. The Achievement Scheme Guidance Notes are the bible. Sadly, a lot of Examiners are unaware of the existence of this resource. If you don't believe me, ask Andy Symons or your Area Achievement Scheme Coordinator. You are being tested, not your model. 1 Quote Link to comment Share on other sites More sharing options...
