    Hello Basil On a Sonata E I built a couple of years ago I used a method very similar to Ron's however instead of using rubber bands to hold the spoilers in the closed position I used small magnets. One advantage is a positive closure that will not degrade over time. Another is that once the magnets have opened they no longer exert any force so the servo doesn't have to work so hard as it is air pressure only. I used a small servo with a standard arm but at right angles to the spoiler (not inclined) and pushing against a small piece of epoxy sheet to provide a bearing surface. Ron can achieve identical opening of the spoilers by adjusting the end point on the servos. Mine are mounted on small racks that allow a small amount of mechanical adjustment to achieve the same. Both have have the advantage that there is no direct link between the servo and the spoiler so there is no chance of stalling or buzzing the servo in the closed position. A small gap in the closed position allows the magnets / rubber bands to do their work. I didn't take photos during the build but I could do if you would like. Levanter

    I see that the 4 Max disposal advice was published in 2010 so is even older than the BMFA advice. Perhaps they would like to update it? I don't have any of their equipment and I am not based in the UK. Perhaps a regular customer would be taken notice of. Levanter

    Hello Rosso I have an old kit I am dying to build but I don't have the ribs or any details of the ribs. Joining the queue for when you are up and running. Levanter

Cheers & keep the faith Chris Hi Chris (The one from Belgium) You forget that since 1st January 2021 we can make our inches as big as we like Levanter

    Sophisticated Lady Pretty much the standard kit except I added a tow release. Turned up from brass it also acted as a nose weight and as luck would have it, CG position available by adjustment of battery position. Hence the the slightly blunt nose. I have no idea whether it will be of any use as a tow plane would have to be able to fly quite slowly not to pull the wings off. It also has the hook for a bungee launch. Levanter

    I will confess to everyone that I have not yet learned how to fly so to answer Chris's point truthfully, I have no idea what I want to do with it. Someone else hopefully will maiden it and if they produce nasty characteristics they won't get used. My flying opportunities are limited (I live in Mallorca) but I love building and try to do something different on each build. So far I have not built anything with retracts, ducted fan or sea-plane and all are on my list. A good point though Chris and again thanks to all. Levanter

    Thanks for the advice everyone. Being a Peter Miller design I think he uses a fairly low wing loading so lift should not be too much of a problem as he says he designs to "fly on the wing" I suppose instead of brute power. I think I am heading towards a full flap for its merits on lift. The power comes from a Saito 40a swinging a decent sized prop that should give some braking along with the fixed undercarriage. In a way I also think it will look better in use. Levanter

    Latest project is to complete all the old "latest projects" and Oodalally is back on track. For a bit of fun and an experiment I decide to fit flaps and at the moment these are simple flat plates. I have two options: One is to have a simple split flap with the plywood plate flap hinging down under the fixed trailing edge. The other would be to have a loose section of the trailing edge glued to the top of the flap so that the camber of the wing would be increased, albeit having sharp exposed edges on the top surface of the wing with the flaps down. It would be easy to build either way but I wonder which option might work the best? Seasonal Greetings to all. Levanter

    What a fabulous location! Where is it? For me, the fact that the image stays upright due to the stabilisation make all the difference. Are there other cameras that can do this? Especially ones that maybe don't have the 360 facility so that more aerodynamic installation is possible. Have you got floats for your Beaver - you should have! Levanter

    I have a 2m Sonata converted to electric (again half finished) that has spoilers so it will be interesting to compare the two. One day that is! Levanter.

    Thanks Peter and MattyB I'll just go with the advised travel on the plan. Just one more question. How do you get inverted? Off the top of a loop or bottom of a bunt? I image it will be seriously unstable. Levanter

    I have had a part built Sophisticated Lady on the shelf for some time and this week I decided to finish it off. Not having tried film hinges before I thought I would have a go using this method for the elevator. Many many years ago I built a Caprice and that has a de-thermaliser tailplane to put it into a descending mush when the fuse burns through. Following this theme I wondered whether the elevator alone would have enough authority on its own to put the Sophisticated Lady into a mush. The reason for asking is that with the film hinge I will have limited travel in one direction and say up to 90 degrees travel in the other. Should I therefore arrange to have as much up-elevator as possible and more limited down? Or maybe it's not going to work anyway so it doesn't matter. Levanter

    And me Mine got stuck forming the second flap and when I found that I had made the nacelles so that I needed custom tanks or accept a very low capacity. Mine will run on 2 OS26 FS engines so probably I don't need much. Because I live right next to a harbour and miles away from an airfield I have taken to building some boats. Also a flying boat to keep my hand in. Very nice work Simon Levanter Edited By Levanter on 04/07/2020 18:12:40

    David This came as quite a shock. Maurice was my godfather and somehow, and I don't know how, my family lost contact. The photos are quite unmistakably of him although my memories are from a long time back. I remember him as a quiet reserved man but with a warn smile and clearly something very special going on inside. He must also have had considerable patience with the demands I surely would have made of him as a small and boisterous child. It is extraordinary that I did not know about his wartime experiences and plight but this seems to be a resounding feature of these brave people who simply saw it as their duty. Youngsters themselves drawn into the most horrific of circumstances in all ranks in all forces. I am sad but hope that he enjoyed his long life. As it happens, my other godfather was a pilot too but after the war. He died about 10 years ago but as a test pilot mainly involved on the English Electric Lightning that required a certain type of courage also. I am humbled by these people and will reflect while I putting together my next model aircraft. Bye Bye Maurice from Tim.

    I was once described as having posted one of the most bizarre comments on this forum. I no longer claim this accolade as it surely goes to Nitro Flyer and I wish you luck with that one, you will need it. Levanter

    I built a Toot Sweet a couple of years ago. Here it is with an OS 48 FS Surpass along with its little sister Yuppy Love. Fits in beautifully. Another view. Has not been flown yet Levanter

    I have joined myself to my models many a time. Worst episode was when the top came off and a big splash glued my shorts to the chair and me to my shorts. It wasn't the stickiness that was the problem it was the heat generated causing burning. The parquet floor was not improved either. Most irritating feature is when my smart phone does not recognize my fingerprints. Levanter

    Jason Do you have any idea how much it would cost to mount a legal challenge against the government and how little chance it would have with such a small lobby such as ourselves. I for one would like to distance myself from your views as aired on this forum and it would be a great disservice to other aero modelers if your attitude means an early prosecution is connected with a model aircraft and not a so-called drone. Are there no boats in your part of the sea? Levanter

    Hi Martin Is it possible, given the moronic treatment of the motor, that it is the wrong needle, the taper altered or has been shortened perhaps? Happened to me with a Supertigre 29 that looked fine in the photos but actually had been ruined be disc sanding and wire brushing. Went in the bin after salvaging the con-rod for a sculpture.
