|Thread: Civilian Coupe (1932)|
Nice subject Tim And glad to see you have the crayons out again.
I will be following this with interest, always good to see how you tackle design challenges.
|Thread: Destiny, My new design.|
And almost certainly Shenstone got the concept of the elliptical wing from his time working in Germany in the 1930's. The advantages of elliptical loading were first recognised by Ludwig Prandtl and his colleagues at Gottingen at the turn of the last century.
|Thread: LIPO charging bags - are they any use ?|
Really sorry to hear about your house Chris, hope no one was hurt and that your insurance covered this.
I take the view that low risk but high consequence merits taking certain precautions. I have no garage and charge my batteries in the house, but always keep an eye on them. I place the chargers and batteries in a large ex German army shell case, if I had a hint of a problem the lid would go on and I would take the lot outside.
It is not just the fire that it an issue, but the toxic fumes generated by LiPo fires are horrible and would take a long time to ventilate.
|Thread: Electric Power Train|
The Gibbs guides are very good introductions to this area
|Thread: Rcm&e and traditional building|
I too have cancelled my subscription, but I will buy the odd issue after reviewing in WH Smiths if there is a good plan or article that interests me.
I empathise with the summary made by Peter Miller. For me personally there are too many reviews of ARTFs and relatively little aero modelling content. I spend more time reading aeromodeller despite the fact that it does not have a lot of RC content.
|Thread: Transfering fromplan to balsa|
As above and I also use this stuff a lot for tracing parts and drawing up plans:
I have a roll which looks set to last many years

|Thread: Mixing brushless motors, ESCs with water!|
Just an update on the progress of this project.
The project is proceeding very nicely and there is a website and Facebook page for any one interested.
I have done aero design work on a bespoke propeller as well as assessing the likely performance of off the shelf props like the APC series. We have done tests on a scale model and just started tests on a full size prototype boat and the initial results look encouraging. The detailed measurements of boat drag vs speed and propeller performance on the full size boat will start in a few weeks, but the initial trial/shakedown shows the boat speeds vs pedalling cadence and perceived level of effort are in the right ball park. The boat cruises in the 4 to 6 mph region and has hit 9.5 mph. I am sure the performance will. Be improved with the development work planned.

|Thread: Stunning Spity pics|
Wow! Amazing pictures, I really like the photo of PoD in the RR spitfire, what a close up.
|Thread: Flying air board|
Amazing! I loved the elephant video also.
|Thread: I'm the real thing, you're just playing at it, he's a danger to us.|
I think the great thing about the hobby is the broad spectrum of disciplines involved, from aerodynamics, designing, building, assembling ARFT's flying, repairing etc. It is up to the individual how many or few of these they care to indulge in and enjoy and I do not judge people for their choices.
I have to say that I believe aeromodelling is the discipline of designing / building model aeroplanes and flying them is a distinct activity. That is my personal view and I do not think less of people who only fly ARTF's as many of them are far better fliers than I will ever be.
|Thread: Classifieds (Misty Levesque snr)|
I have just received a similar email from this person.
I judged it to be a scam based on the illiterate wording and unlikely name.
|Thread: Scratch building, or is it?|
I don't agree that my definition precludes scale models at all.
My definitions for what they are worth:
Drawing up and building from your own plan: scratch build.
Starting from a plan: plan build.
Starting from a kit: kit build
Assembling an ARTF: assembly.
I am sure there are other shades and that this is subjective, but the words ought to describe what is involved in the process of making a model aeroplane.

|Thread: Poor Ron|
I thought he was trying to commit suicide by slashing both wrists simultaneously at the start of the video
|Thread: Caption time again!|
You're gonna need a bigger elevator!
|Thread: Craig's first build Ballerina|
Every plan I have shows balsa formers with the grain across the fuselage width. Perhaps someone should tell the RCME draughtsman, to be fair I think most plans I have seen are the same.
Given the number of models that Peter has designed and built, I would follow his advice on these matters. I suspect that once the fuselage sides are in place it will have adequate strength in either direction.
Not according to the plan on Craig's wall, see a few posts up.
I think you want the grain in the other direction on your formers, that makes it stronger laterally and less likely to break like that one did.
|Thread: Rules of thumb for electric flight|
Power is proportional to N^3 and D^5 not D^4
Thrust is proportional to N^2 and D^4
where N is rotation speed and D is the diameter.
