Sorry Rich missed your post. I was with 493 Kings Heath & Moseley Sqn -
Tiger Moth DH82 by Value Planes
Ady Hayward replied to Geoff Daunt's topic in Scale and Semi-Scale kits
Hi Geoff. Sorry I missed your post. I'm guessing you sorted the tube bending but for the record I 3d printed a series of "Pulley wheels" of suitable diameters and carefully helped the tube around until it fitted the drawings. Small adjustments were made using firm finger pressure only to avoid kinking. A little perseverance paid dividends. I did find they often broke free so a little fine thread wrapped around will hold them firmly in place.. -
Tiger Moth DH82 by Value Planes

Hi Geoff. I am a very experienced builder of model aircraft and found building one of these was a bigger task than first expected. The kit in itself has many of the metal fittings and fixtures on two laser cut plates and the mix of woods in the build is comprehensive and has most parts laser cut from lite ply. I decided to build it as close to scale as possible as the side and plan profiles are pretty accurate. I intend to use it for stand off scale and went into the detail maybe a tad too far. I soon found that apart from the outline there were a lot of extra jobs to do. It is intended as a sport scale and is closer to a DH60M "Metal Moth" of which the DH82 is a direct descendant. In this respect the aircraft lacks the wing sweep on the top surfaces and the corresponding forward placement of the top centre section. I found this out when at the rigging stage and found the official measurements didn't correspond to the aircraft and thankfully a slight re adjustment of the centre section metalwork had everything lining up as it should. When built the bare airframe looks a bit like the incredible Toni Clarke super detail model but that is as far as the similarities go. With respect to the cockpit I ended up making a new control box from an actual control box scaled down and still managed to get the rudder and elevator servos under it to operate the controls in a scale manner. I also ended up getting as many full size drawing files to scale down the instrument panels, seats and internal controls and other fittings which were then 3D printed. Not a task I would want to repeat too soon. The undercarriage is a very simplified affair and far from scale which is my next project to attend to. To be honest I would recommend it as a large semi- scale model unless you are willing and able to create the scale fixtures and fittings. -

Hi Richard. Just found this. Yes this one represents the first Chippy that I flew whilst in the ATC. 8AEF had by far the most colourful and pleasing scheme of them all. A little bit of bending the rules regarding the markings and dayglow strips -
Old Warden Scale meet - who's going?

I'm intending to go. Family, weather, pain and pestilence permitting. -
Warbird Replicas Ju88 Night Fighter build

Nice flying Eric. I found with mine that dropping a just a couple of degrees of flap made the plane feel a lot better when flying scale like. The 88 is a lovely plane to fly -

Hi Folks. Just chipping in. I found mine to be the sweetest twin I've ever flown and on the electric motors recommended has no shortage of power and flies well on one engine as I found out and the rudder is amply powerful to hold things straight. A video was posted of it in flight which you may have seen before: -
Hi Folks. I thought the thread had closed and was surprised to see it was stirring interest. The Javahawk is still airworthy, and on its 3rd fan unit. A 55mm unit is the smallest I would suggest to allow the motor to be throttled back a little in flight.

I have a Laser 120 in mine and she's nicely powered. The engine is quite compact and has plenty of headroom (Foot room?) inside the cowling.

Building board - recommendations please!
Ady Hayward replied to Ian Whittaker's topic in All Things Model Flying
Hi. I use end grain balsa insulation boards. Easy Composites is but one UK supplier. It can be supplied in various thicknesses and has a cloth type backing which enables it to be glued in place. I fixed mine to a 12 mm MDF board 2 m long by 0.75 m wide, 25 mm thick and fixed it down with spray photo addhesive. I sanded mine perfectly level (as far as can be done) and it has been in use for a couple of years, with many more to come. -

Yay! I got the maiden and a couple of follow up flights in yesterday. She flew as sweet as all the others that have been posted here. The laser 120 is maybe a tad low on power for the vertical manoevres but looks a nice scale like combination none- the-less and needs a gentle dive to do a round loop. The wash in on the port wing has crept back in a little so she will stall to the left in an accelerated stall but she's predictable. Spins either way are good, and to the right enters a 1 turn spiral before the spin develops and stops within 1/2 turn when recovery is initiated. Maybe the Spin strakes are having some effect. I practiced the scale schedule plus a few extra attempts at spins and loops and found I still had 2/3 of a tankful left. Very frugal compared to the Gemini 160. The only issue in the three flights was on the 2nd flight when a flap clevis (M2 metal) that pulled off the threaded rod but even then on the approach when full flap was applied I saw the flaps come down together initially then an un-commanded roll which was easily overcome by the ailerons followed by another as I raised the flaps but made a safe landing anyways with the port flap flapping in the breeze. Now I have to find some threaded rod that will take solder as most of the rods I have are of Oriental origin and are non magnetic and don't take to solder.

Hi Cliff, Nice one. I'm really glad to hear things worked out well for you. I hope the York gets finished, its a nice subject.

Hi Folks, I finally have my Chippy ready for her maiden. Has a new Laser 120 fitted instead of the Laser 155 so there is a little more space in the cowling for the baffles to surround the engine. All up weight is 5.3kg (11lb 13oz) so nearly 1 lb heavier than I wanted even with built up balsa tail feathers so I am somewhat bewildered how Seagull recommend a typical 4.8kg (10Lb 9.5 oz) auw on the box cover. No ballast is fitted and she balances out between forward and rear limits with an empty tank. With the original tail feathers she would have ended up closer to 5.75kg-6kg due to the extra nose-weight that would have been required. Still she is what she is and should fly OK at her weight. Engine runs were uneventful with no apparent overheating issues and sounds lovely with the stock exhaust and scale like exhaust. The last item to be done is to source a light weight pilot for the front seat. Ady Edited By Ady Hayward on 21/11/2020 20:12:11
