Mr Ficky

Thanks Martin for your reply. I was wondering about using silver solder, so I'm glad you mentioned it!

I've been using Hitec radios for the last 15 or so years, and I've been quite satisfied with them. However, I'm thinking of changing radios as Hitec no longer manufactures them. So, what radio would you recommend? No doubt I'll get a variety of answers, but I'm happy to look at all viewpoints. Generally, I don't think I'll ever need more than 6 channels, and I do like to keep things simple. Thanks in advance!

Has anyone got this particular mitre sander they don't want anymore?

Oh dear! Its unfortunate as I've placed my order for the Radio Modeller Jan 1984 issue. The last paragraph in the Dec 1983 issue states: "Thus plan feature is unusual in that it has been split over two issues, due to the fact that Ben has supplied a great deal of information on building the scale interior in addition to colour schemes. This information and the full flying notes will be published next month". This Jan 1984 issue should be delivered within the next week. It will be a shame if what you say is actually the case. Thanks for the heads up!

Thanks Robin. I've contacted the seller!

Does anyone have the Jan 1984 issue of Radio Modeller squirelled away! I need it to complement the Dec 1983 issue (that I have) where the Super cub is featured.

Doh! Ficky by name, ficky by nature!

As you can see on the Ben Buckle plan of my Super Cub, it says the elevator is All MATL. 1/4". Does anyone know what MATL means?

I'm still constructing the wings and I am having a D box. I haven't as yet put the lower and upper sheeting on as yet, but I have put the webbing in and the wing is quite stiff; I've also put 1mm carbon strips down the length of each spar contributing to the stiffness. So I'm thinking too, of using the struts to create washout, as it's a little too late to build it in the wing - I could give it a go when gluing on the sheeting. I'll only put in a max of 2%. Martin - is it possible to post a photo of your redesigned struts? (I was thinking of using spruce and shaping it).

Many good comments - thank you! From your comments I'm thinking of putting in a small amount of wash out using functional wing struts. So, with that in mind, how do I create this? Martin Harris - would you be so kind enough as to explain how the struts are made and attached on your Premier / Aerotech cub? Is it possible to make the struts so they can be adjusted to get the right amount of wash out?

Oh right! Do you get any tip stall?

Can any of you Super Cub Flyers / Builders tell me if you have experienced wing tip stall at slow speed? As the Cub is a parallel chord wing, I'm assuming that it doesn't need any wash out; but I've read that the cub is prone to tip stall. What's your experience?

I'm building a Ben Buckle design of a Piper Supercub; I believe it goes back to 1983. May I ask you Super Cub builders whether the wing tips should be as picture A, B or C?

In Dec 2022 RCM&E, page 84 it mentions the 'Eric Coates method' of building a tail and wing tips. Can anyone shed more light on this? Is it describing the same method that Peter Miller describes in his book 'Designing Model Aircraft' on page 53?

I used the following sealing pen that I think I got from the RCHut in South Wales. From memory it'll do about 3 planes and cost around £15.

Hi Lucas. The wing struts could easily be removed, but with this size aeroplane I tend to keep it built up as it fits in my van without any dismantling.

Here's a picture of the aluminium strut. Sorry for the delay.

Yes, profiled aluminium.

Thanks for your suggestions and comments. I did think of the DB S & S, but I think it's a bit too big for me. I'll check out the Flair Cub. 😃

Your build looks great! I finished mine earlier this year. Enjoyed it so much I'm tempted to build another!

I'd like to build a cub for my next project. I'm not vastly experienced at modelling but I'd like a challenge, and something not too big. I'll also be flying electric. I'm tempted to get the plan from Sarik for the clipped wing Piper J3 Cub, (56") designed by Phil Kent. Has anyone got any experience with this plan? What power set up did you use? Any difficulties building it? How does this plan compare to the other cub plans? Any advice greatly appreciated.

Thanks everyone for such good suggestions! PatMc - wings are very balanced, I just checked; but I also built them balanced, even weighing the balsa. Piers - thanks for your comments! And also explaining what happens when approaching a stall turn! Makes sense! % Thrust: In looking closely I notice (with my protractor) that i built the firewall with 2% of down thrust - doh! I have therefore put a couple of washers on to bring it back to 0% down thrust. But I have put in 2% right thrust - sorry Peter! As a result I have re-trimed the rudder to 0 - but I have shown a picture of the rudder before I changed the thrust line. Is this too much just to enable vertical flight? Peter - nothing is obvious to me as it's my first build! I've took some pictures, perhaps you could advise (if the pictures are good enough) on whether you think the angles are ok? The next picture is showing the angle of the elevator to enable straight and level flight - is this acceptable? Battery: As you can see, I have a 3300mah 3 cell lipo, and you can see where it is to obtain C of G. I believe this battery is larger than then recommended. I went for this as originally I built a Rans S9 Chaos (yes, this is my 2nd attempt!), and it really was EXTREMELY tail heavy, so bad that I was afraid to maiden it, and I put it in the bin! When buying the second kit, I thought 'try and build light and get a heavier battery!' The plane weighs 1910 grams. C of G is 8cm from the leading edge, (closest to the fuselage). I'll have to check with the article that this is ok! As I've said before, comments and suggestions are really appreciated, and I mean it! Please keep them coming.

Thanks Peter and Graham for your comments! Much appreciated! A couple of guys at my club have said to check out the thrust line, but isn't it true Peter that you always have 0% thrust on your models? I am probably going to put some thrust % in, but I'd appreciate your comments on this first Peter, if you would be so kind. The equipment including prop, is all the recommended from 4max. Peter - should the elevator be at the same incidence as the wings? Mine isn't. Flying it today, it was going vertical for a stall turn with no veering to the left, but there is a LARGE amount of rudder trim on. I only had 2 flights, as I nearly crashed it due to me trying to rectify how it flies. Any suggestions on what to do is much appreciated.

After completing my first build, and having flown over 20 flights, can anyone help me answer why my Rans S9 Chaos is behaving like it is? 1. When climbing for a stall turn the plane veers off to the left very strongly. In general flight, it flies straight and true. 2. When doing a loop, as it gets to the 12.00 o'clock position, it wishes to close the circle instead and fly off at an angle, instead of keeping to the line of the circle. 3. In order to maintain straight and level flight, a lot of up elevator is required - is this normal? It is balanced well. It flies inverted quite well, and maintains an inverted 45° line quite well with no significant drop. It would be sad to retire this plane to the hangar because of it's annoying aerobatic characteristics - perhaps I need to modify something? Any help would be much appreciated!

Thanks Shaun! I'll get a charging cable suitable. It threw me as I would have thought that the different charging cables would have been included in the purchase of the charger.
