|Thread: The Atom Special|
At long last I have started my Atom. My normal approach for any model build is first produce it as a kit, and so far it's being produced from my scrap boxes, which I find very gratifying. ..
I have two sets of AJ blades one have been balanced and covered. The 2nd set I will increase their chord to 50mm and their thickness to 6mm then re-profiled LE as recommended by Rich (sharp LE) ..........The rotor head is own design and I'm trying out a mast made form 12mm aluminium aerofoil section tube,....... yes I know time will tell, but to have never tried one would never know...........This philosophy has served me well throughout my years of modelling.
Phil, Yes I had the same happen to me a few years back, but today my two old buddies and I have that frequency virtually to ourselves.......
Signal failure was one of the reason I kept to 35meg and can honestly state I have never ever lost contact with any of my electric fleet,. Even in the early days of electric with can motors and NiCads..Another reason over the years I have invested heavily in Futaba 35meg.. All the "Glitch" hype was branded about to sell 2.4
I do own a Spektum DX7 but only use it for flying small hellies in my garden .
If there is anyone interested I find this hand held blade tester very handy (no pun intended) to check out new blades. prior to fitting I on the model, and. If you have the patience you can achieve reasonable dynamic balancing .
You have a nice looking model there. It might be just the picture, but it looks as though your blade roots look a little too long, there should be about 14mm between blade root end and the blue triangular flex plate clamp
I bought a C30 head a few weeks ago. An old pal wished to make the Atom so I let him have my C30 as he had no means of going on line. It was only then I found all heads were out of stock ...so undeterred I decided to make another one. This is the second one made as the first worked out too heavy . The one pictured worked out 4g less that the C30.
Max glad to hear you said "temporarily unserviceable".
They look very nice pair of models, so does your flying site
A good bit of lateral thinking on your part. Did you make it from Depron?
There have been one or two posts about the lack of rudder control. When making my Atom I was thinking what Rich said about trying a central rudder aiding the others. I was toying with the idea of increasing the rudder area but not the rudder and fins overall size. My Idea is as this sketch By trimming the tail plane thus enabling to move the rudder hinge line 25mm forward.

Have you settled on using your 35meg? I have only ever used 35 on all my electrics and never had an issue, but on any small model I use a GWS receiver which has a short aerial, that will be my choice for Atom..
I like what you have done with the rudders a really good idea . You can not beat having good rudder authority especially with any model on take off.
Good on you Max, As for your posts, I like what I read as I finding it very informative..
NIce one Tomas. I use one very similar for fine finishing after planning...
My sanding bloke was made of two 1m lengths of 25mmx25mm aluminium angle riveted back to back but I only use 30cm strip of sand paper stuck on with double sided adhesive Sellotape . This allows for longer sanding strokes..
You want your blades just free enough to move in case of a bad arrival.
If you scroll back and look at the video Rich put on site you will see just how the blades react to unintended arrivals, This was in the early days of gyro flight. . Luckily for us Rich has past on his experiences and 'do's and dont's' which has enabled many a modeller to enjoy autogyros.
That looks champion Max, and you home brew rotor head looks the biz. Best of luck with the maiden ..
Well Rich 10 0ut 0f 10 for persistence mate, and I for one am glad you did. There's an old saying, if you have never made a mistake you have never made anything.....Good on you.
My thoughts on that sharp LE section are it creates uniformity to each blade, once you round the LE you create a certain amount of positive incidence, and you could end up with each blade having different incidences even through out the length of each blade LE.......Just supposition on my part...

Great stuff Mike, you are almost there. If this blessed weather continues I can see mine will soon be on the building board...
I too have increase my blade thickness by 1mm, I have cut strips of 1mmX10mm birch ply to be glued to the underside of the blade LE, but making sure it is proud of the LE by 1mm., this allows for re-profiling the LE to obtain that sharp leading edge. The rest of the blade will be made up with firm 1mm balsa sheet.. The TE once sanded I firm up with thin syno.

If in doubt PM Rich and ask him to send you his blade PDF, In your PM add your email address. You can print it off A4 size
