Humour / Mary
« on: December 05, 2012, 00:22:54 AM »
Mary had a little lamb,
She also had a bear,
And everywhere that Mary went,
You'd see her bear behind.

Aah! my kids love it

Control Line / control line laystraight wire
« on: May 21, 2012, 00:30:18 AM »
Hi all,
       Reliving my youth with my brothers, yes  we are building control line combat wings Dominators to be precise with PAW diesel engines to fly combat together as we did in the early seventies. Question is, can the wire be obtained anywhere in Ireland?

Scale / Slingsby Tutor T7
« on: May 05, 2012, 17:15:26 PM »
Hi all,
       I've been busy these past rainy weeks with my 25 inch span aerographics kit. I covered it with lightspan (more difficult to apply than tissue and dope,but much stronger for similar weight). It's 2 channel 2.4ghz micro radio gear and all up flying weight with ballast came in at 38 grammes. Just need to add a pilot now and wait for the right flying conditions.

Slope Soaring / Battery flight time
« on: March 08, 2012, 00:22:41 AM »
Hi all,
      I got this to teach me how to fly (fed up wrecking planes). I am using a 350mah lipo to power the 2 servos ubec and receiver, servos draw 200-240 ma. Am I correct in assuming approx 1/2 hour flight time?
Thanks

Slope Soaring / Glider info
« on: January 16, 2012, 00:14:02 AM »
Hi all,
       Anyone got any info on this glider? I can't find anything on the net. Might fancy as next project for a lightweight sloper. The wing construction looks quite unusual but would have to make the tailplane correct to scale. I like that shape with the faired in wings.yea I'm a scalie at heart.

Scale / Airco DH2
« on: January 04, 2012, 00:03:57 AM »
Hi all,
      I have began my next project, it's a first world war DH2 of the type my grandfather flew, bought in kit form (aerographics), 28" span and my plan is to convert it to 3 channel rc with electric power.
Some work done on dummy engine
 
And the lewis gun,  wicker seat and inst panel


More to follow,

Slope Soaring / Foam Quark
« on: December 20, 2011, 21:18:03 PM »


Hi all,
     Having never worked with foam before I have decided to have a go at making a foam 1.6m Quark as per Freds plan. Two unsuccessful attempts with an assistant at wing cutting in one go I decided to try it in two stages.I started by cutting blocks of foam 5mm all round bigger than wing size  I soldered wires to the templates(in the pic the wire is broken off the back of the root template, I caught it in my jumper). I double sided taped the templates to the block ends (checking allignment) and with an assistant managed to cut 2 opposite and useable wings in two passes per wing of the hot wire.  They needed a little sanding to remove lines caused by slow wire speed at the wingtips. Cutting wings this way requires a little sanding of the leading edge ( you can see the waste that needs removing on the leading edge in pic.) and cutting a sliver of foam from trailing edge using a knife and steel rule.
             The small wing below the foam is a test piece which has the same profile as the quark wing. After it was cut I rolled it with a coat of PVA glue, allowed it to set off somewhat I then glued out craft paper using the same glue and roller and covered the wing top and immediately after covered the bottom and then weighted it down to dry. The result is a good stiff wing which hardly requires a spar although I will fit one.
            Paper finish is difficult to paint so I will most likely be taping also.

Slope Soaring / Blast from the past
« on: December 14, 2011, 22:29:57 PM »
Hi all,
       Rooted this out of the back of a wardrobe in the brothers place. He used to fly it in the early 90's. The covering was ruined so I stripped it off and recovered in craft paper, just needs paint now. It has big control surfaces so I am hoping it will perform.

For Sale / Retracts set swop
« on: December 04, 2011, 00:12:55 AM »
Hi all,
       Have a set of unused mechanical retracts with fittings and tailwheel from my 1200mm spitfire. Will swop for 2 servos 12- 14mm thick for my middle phase wing. Anyone interested?

PSS / Spitfire maidened
« on: November 24, 2011, 00:12:09 AM »


Hi All,
      Flew my spitfire at Killakee slope yesterday I was most surprised at how well it went considering it was not very windy, under force 3 . It doesn,t penetrate very well (guess due to thick wing section and big wing area) but soars really well. It needed loads of aileron throw to get it turning properly its also quite light at 1kg all up. Looks great zooming around and put a smile on a few onlookers faces. Delighted with it and managed 3 flights without any damage. Have to make a pilot.

Slope Soaring / Ploof
« on: November 22, 2011, 00:53:07 AM »
Hi Fred,
          I saw your ploof with full elevator movement, how does it fly (flips?). I really like this glider and am considering building one with a fully symmetrical wing, & full moving tailplane as yours. It wont fly inverted very well as standard  Have you still got yours, if so would buy from you (remake wings and have fun). I really like this glider fast & demanding.

Slope Soaring / Tip stalling
« on: November 03, 2011, 23:49:57 PM »
Hi all,
      Having problems flying my DG1000. I keep tipstalling it on final downwind turn to land. My Dad suggests that my turn is too flat and to put in loads of bank. He says the full size ASK6 was notorious for this and many were crashed on finals. Do models behave the same? Hopefully will try again on Saturday. Had some great flying last weekend at killakee with my phase, strongest winds I've yet flown in 30 knots +gusty, was great to learn to fly backwards and so easy to land. Course I broke it eventually but got a good hours flying.

Slope Soaring / google warnings
« on: October 27, 2011, 23:07:23 PM »
Hi all,
       Spent a great afternoon flying at killakee slope this afternoon. Maidened my hobbyking canary. It flies really well very responsive for rudder and elevator only and handles the gusts well. On the first launch I crashed to the right while applying full left rudder, you guessed control reversed. How could I not have noticed after hours of messing about with it on the bench. Anyway no damage and easily sorted.
Why is google chrome warning me not to visit this site displaying the message that it may harm my computer, is there a problem?

Slope Soaring / Yet another
« on: October 03, 2011, 00:22:53 AM »


Hi all,
       Another china glider, a simple 2 channel control 1200mm span, weight with ballast 340grms. It came without instructions so wondering where to setup CG. At present I have added noseweight to put it 1/4" forward of wingspar at root. Hoping it will be a nice relaxing model for those nice balmy days.
John.
