Thread: The Atom Special
15/06/2018 12:24:17

Hendi,

Glad to hear you are back on track with some modelling, it has been the same story with myself. Our daughter was born in 2016 so modelling has been put on the back burner, now she is on her own two feet I have managed to get out to the field once or twice. As for designing and building the urge is starting to come back but time is the limiting factor right now.

Regarding your blades, you have made a good job on their profile and your weights are very close, any chance you could take a photo of where your CG lies please? If it is a mile out there are a few tricks we can use to bring it into a more useable position.

Unfortunately AJ blades went out of business so the Atom blades are no longer available, that said, I am willing to make up sets at cost for anyone who requires a set but would need notice to get materials.

The Atom was designed quickly specifically for the Special and to fit within a few pages of the magazine, there was no full plan only the templates and the instructions. The whole concept of template/write up worked as there were well over 100 examples made around the time that I knew to.

I agree with the above, just don't think an 049 will have enough power. No reason at all why you couldn't convert the Atom to control line, though there is no need for a flapping head as per the RC version.

My Dad still gets his control line stuff our from time to time and we were working on a profile Kayba that could be switched from CL to RC, the CL version works well but the RC version never progressed past the design stage through one thing or another.

The head is fixed at around 7 degrees rearward tilt (I can get a more accurate measurement for you if you like?), the blades are profiled and are rigidly fixed to a blade holder with negative incidence machined in. The blades rotate in a clockwise direction and  will automatically try to make to machine roll left keeping the lines taught.

Motor fitted is an OS 40 with a throttle operated off a servo through an old 35 meg receiver, he has utilised 35 meg innards of Futaba challenger transmitter which he holds in his left hand. You will notice there is a rail sticking out of the fuselage, this is a guide to keep the control wires away from the and as per the fixed wing CL is located on the CG.

Hope this lights the wick and please let us know how it goes?

Nuno,

Yes, you can use the same type of head just remember to upsize your servos to suit.

Ken,

Why don't you finish it? if you can upload some pictures I will post it onto the FB group.

It is with great sadness I have to report fellow club mate, friend and scale modeller David Vaughan passed away after a short illness on the 28th February. He was ,without doubt the best scale modeller I have seen and one of the nicest people I have ever met who will be missed. RIP David.

Thread: Falcon 3 blade Pusher
19/02/2018 21:40:03

David,

I have built this kit and probably have the plan stashed away somewhere. But if I'm honest its not the best flying model and needs modifying to fly anything reasonable.

One of my old friends who is no longer with us designed a far better machine of which I'm sure the Falcon gyro was a copy of. The Minimum is a great flier and designed by someone who knew what they were doing, unfortunately the aerobalsa blades to which it flies on are no longer available. That said Atom or Cruiser blades should fit the bill perfectly and are easy to make.

Plans for the Minimum are HERE, if you need any assistance with the build just post away.

Thread: Cruiser, November 2015 Free Pull out plan
11/12/2017 17:28:41

Taking full advantage of the near perfect flying conditions over the weekend I decided to fit a set of skis to my enlarged Cruiser which has flown well all season on a 60" span two blade set up in pretty much all flying conditions.

Saturday saw an inch or so of the white stuff here in the West Midlands and managed to grab an hour in the afternoon to take her out and flatten a few Lipos. There was only me at the field but I enjoyed every minute. I took a few snaps and some video footage but it wasnt until I played the video back that I realised my daughter who can now pick up and play with pretty much anything shes not supposed to had obviously been playing with my phone as the camera lens had little finger prints all over it!. These caused a blur to the right hand side but I uploaded it any way. Unfortunately I couldn't get back to the field on Sunday due to more snow.

Good fun, enjoy

Thread: Panther Trainer Autogyro
19/11/2017 16:12:07

I received an email during the week from a gent called John over the pond in New Jersey,USA. John has just completed his Panther and has modified it by adding a stub wing to help him with orientation. Though not flown as yet I thought it was more than worthy of a post as he has made a cracking job.

Its great to see these models still being built, I will hopefully get a full flight report back in the coming months.

Thread: My Spektrum DX9 transmitter has stopped working.
06/11/2017 21:29:05

Gents, Unfortantely after a couple of years trouble free use my DX6 (black edition) has developed a fault in that after maybe 2-3 minutes I loose signal. I have now lost 4 different models which 'freeze' on the inputs being used at the time until terra firma gets in the way. The transmitter (up until now) has been really good, so much so that I have got quite a number of spectrum receivers that I don't really want to get rid of. As its just a simple transmitter I am unsure whether the cost is worth sending it over to Germany as it may be  just as cheap to buy new. That said Percy mentions a Mr Riley a few posts up, is he able to repair Spektrum stuff or is there anywhere else within the UK that could help?

Thread: 'Bitty' multi purpose micro glider
06/11/2017 21:18:16

Paul,

Sorry for the delay in replying, my internet/ aeromodelling time is limited at the moment due to the pitter patter of tiny feet.

Thanks for taking the time to make a video of your 'Srappy' in action and glad the boys at your club are having a blast, just goes to show you can have just as much fun with minimal outlay models which is what Bitty is all about.

Your release cradle is pretty impressive too, I am curious as to what radio you installed in your Scrappy?

Hi Celab and welcome to the forum smile

Before you go spending good money on blades that may not be suitable please link us to what you are looking at?

The blades and their aerofoil are key to making the Panther successful in the air, any deviations could be expensive.

Try to steer clear of helicopter blades as these will just not work.

Despite what you may think about making blades they really aren't hard to put together. we can guide you through the process step by step if it helps?

Thread: Cruiser flight problem
19/07/2017 22:42:19

Denis,

Cruiser was a free pull out plan a few years ago, here is a photo of my enlarged version which I have been using as a test bed for a two blade set up with suprisingly good results over the last month or two.

Paul,

Welcome to the forum, what you are explaining could be a number of things. But, if you have stuck to the plan and all angles and dangles are correct it has to be the blades as this is really the only thing that could differ. My thoughts are the same as Steve's, try adding a small amount of shim to the blades. It sounds like you are getting too much lift and when you get to a certain power level the down thrust is over coming the drag/ lift from the blades.

 The extra shim will kill a bit of lift from the blades which will bring the nose back in tow. I would had slithers of tape and test inbetween until you hit the sweet spot. If you have experience on the Atom then the Crusier will cause you no problems once set up, its my favourite flying autogyro to date.

 

Let us know how it goes?

 

Rich

Leif,

Very well finished Panthers, I have always liked Ian's yellow and blue scheme so a good choice there thumbs up

Don,

I have managed to upload a few photos via my phone, I have added these elsewhere so I hope you don't mind me posting them? Kind of gives the feel of our annual meet, great helpful bunch they are!

You may have more left and up trim probably due to the weight but it flies, and flies extremely well smile

Don,

It was a pleasure meeting you and your wife and great to see your Panther take to the skies. I did take a number of photos but am struggling to upload photos onto this site of late.

I have managed one

Thread: The Atom Special
06/06/2017 17:32:54

Rob,

If you have never built a model before you need to give yourself a pat on the back, your build block is excellent too.

Not wanting to put a dampener on things it reads to me ( and please correct me if I'm wrong?) that you have never flown any kind of RC flying machine? If this is correct I would strongly advise to pop to your local flying club and get advice on learning how to fly before even contemplating on going out alone. If you have no flight experience it will end in tears.

You are of course always welcome to bring your creation along to one of our autogyro Fly-Ins through the year to which we would happily get it in the air and trimmed for you and at least guide you on the directions you can take. There is a separate thread listed in the autogyro section with dates, we are about 3-4 weeks away from our main get together, the info should be printed in the next issue of RCM&E if you are interested in popping along?

Michael,

If you get chance have a look at my thread HERE on this very forum, it is a primitive but perfectly functional method that has given many hours of service for next to nothing. There is also a video I made of it working and releasing.

It's videos like that which make all the effort that goes into these published desgns worthwhile, personally it keeps my drive maintained to keep putting pencil to paper, thanks for taking the time to make a video thumbs up its very much appreciated.

Thread: Aeromodellers or model flyers?
03/05/2017 12:40:11

Does it really matter how we are categorised? In my eyes we are all into minature flying machines in some form or another, as long as we enjoy what ever we do then that is what counts surely?
