So the ailerons are now working as they should with the added bonus of being able to add differential if needed, just need to apply insignia, finish the N struts then onto fitting out.

I would use the lost foam method, abit more effort maybe but a much more robust

So there I was happily covering the wing.... .......enjoying my new detail iron........ thinking that it's all going rather well and started attaching the top covering, when I had a thought 🤔 it's been three years since I've installed the aileron system, maybe I should check it out?. Well it turned out to be a bit on the slow side and not centering due to friction and the old(but new) linear servo ,so need to chuck in a couple of servos that were made this century 😄 rather than mess about sticking them out in the wing where the bellcranks are I put the HK servos here,if I need access to them I can open up the top

Wing now fully repaired and sanded down ready for covering when my new iron arrives so back to the fuselage tailplane finally glued on ! Removed the wire tail skid whose main purpose was to punch holes in anything nearby and fit a tail wheel ,at least I will be able to taxi it too where I want it to go rather than where it thinks it should be 😆 also made this storage/travel fixture need to add tailplane strut/bracing wire then onto servo/pushrod install

Thanks Steve, I may get to finish it this time without further extended 'rest' periods! 😂 definitely a better arrangement than the original kit way of doing it, now I can cover the wing and start final assembly, radio and engine installation

Well another one one of threads rises from the dead 💀😄 ! Can't remember exactly why I put it to one side but maybe that I was never that happy with the centre section struts, always thought it poorly engineered.So I revised it too a more stable arrangement.

I have a couple of low time sc 25's if interested, or I may have a ss 25 somewhere in my collection 🤔

Thanks ED ,it's funny you should mention that,I did buy a kit from Chronos with the blue dye with which I tried to do the crankcase/ front, but with a less than satisfactory results,most of the dye being washed out in the sealing process, so it was into the bead blaster which looks o.k. I obviously need to experiment with it and find out where I'm going wrong 🤔 but at least it runs! Nice work Tim you are half way to making a complete engine! Maybe you should have a go?

And just to show it's not just a paperweight

Latest engine build freelance 10cc ,HP 61 crankshaft and Webra liner I am getting nearer to fulfilling my ambition of flying a o/d model with an engine i have made

So I've been doing a quick refurbishment (🤣🤣 nothing I do is quick!) On a genuine KK super sixty that is covered in doped nylon or polyester 'silk ' and for some reason decided it would be a good idea to remove the old fuel proofer/paint/dope with thinners, a decidely messy job.Now this turned out o.k, none of the covering came away and remained tight. it needed doing, no,really it did ! not the best picture but you can see the difference with the doculam and uncovered section Again not the best picture, completed underside.So instead of sticking the tissue/nylon/silk over the doculam try it the other way round for a instant fuel proof finish,with a saving on dope as you only need apply a couple of coats of 50/50 to tighten and no fuel proofer. When I have finished all the covering I'll post some more pictures

Interesting Tim,although I don't think the cdi will do much for the engines power to weight ratio ?🤔 probably better than the motorcycle coil though 😆! My O&R 23 (repo) had damaged points, as in one of the contacts had broken off, probably why it had glowplug in it when purchased, btw don't use methanol in original plastic tank as it will damage it moving contact point with the new tungsten pad silver soldered on Minimag coil/condenser luckily got two off fee-bay worth looking out for

Well it runs but the compression is a bit soft will have to check head volume and squish clearance 20230327_160009_001.mp4

Just about finished with the machining on the Hallem, apart from making the points that will have to wait until I can find some 1/16 brass sheet that's in the workshop somewhere 😏 it's just a case of stripping and thoroughly cleaning and final assembly. I have replaced the original exhaust with this duct I made should help keeping the exhaust muck away from the model (if it runs lol!)

Enya SS50 done just need to find its silencer and give it a run. After a couple of hours working on my super 60 resto ,took some time to make the ignition timer for the Hallem, I had been pondering over its design, the photos I had found didn't really help, however it turned out the answer was right under my nose in the form of a blueprint for the engine (remember most of these were made from kits) on the late Ron Chernich's website Model Engine News

Wow! That went right first time, found some ptfe rod and used the old piston, had to reduce the length of the pin by 40thou You can see that as it travels across the port the pad is in constant contact with the cylinder, so we are good to continue reassembly 👍

I had thought of pads in Teflon or brass but can't help but think that the Enya bros used clips for a good reason ? 🤔 If I make a fixture for machining a radius the same as that of the cylinder on the pads it should work OK, only one way to find out! Will have a go later,meanwhile I've re-machined the fuel tank on the Hallem reducing the thickness from 2.5mm too 1.3 , It's somewhat lighter now! Then made a recess in the backplate missing prop driver next will have to do something about the thread it's well wonky, it's a 1/4 bsf maybe take it down to 1 ba ?

Piston made from 6082T6 just need to do the circlip grooves but it's proving to be a bit tricky setting it up accurately in the chuck! while I'm giving it some thought I have another little project for restoration ..... .

And as if more proof was needed, this lot arrived this week, might have to extend the shelf 🤔

Because you never when you will need one for a new project,and oh! Look,I have just the engine I need too hand best get on with it then. But of course you are right DD ,guilty as charged probably have more than twice that,although 15 or so are projects, 100+ plans,8 kits+500-600 magazines and books, do I need all of this? Heck no,but as our American chums would say 'he who dies with the most toys,wins! '

Very nice Jim 👍looks like a posh junior 60 ,the transparent profilm suits it ,I have used profilm and found it gives excellent torsional stability, if only it was a bit (a lot) cheaper!

Well got to making a start with the covering using my dwindling stock of Hobbyking film, not enough orange left so will be mostly blue.

Kadet plans are on outerzone if that's what you need.

Finally got around to doing the faring on the wing on this project, after a lot of sanding down it blends in quite well. This now means I need to decide whether to go for a all paint finish, all film finish, or a combination of both 🤔 not too mention a suitable colour scheme!!

We must be of a similar vintage leccyflyer ! If I remember rightly the jay-pee had a diamond shaped aerofoil with sexy looking endplates on the wing tips and a profile fuselage.My first real attempt was with a Mercury Marvin a Dave Platt design and a DC spitfire, and with not dissimilar results although in my case it stopped half way through and nose dived straight for me,requiring me to vacant the centre spot rapidly!
