Isn't that a Practical scale ?

Ahh! Peter so we will soon have two in that scheme. I am going in for G-ADNV for exactly the same reasons, no ant spin strakes 😃

The weather has not been conducive to flying over the past few days, neither has it been conducive to working in the workshop either. I have started to paint the fuselage, cowls and undercarriage, but with the freezing temperatures that has stopped temporarily. I have started covering the wings, having transferred the components into the kitchen and put the table to some proper use. Luckily I bought a full 10m roll of natural Solartex a few weeks ago. The paint I am using is Solarlac, I did this as I was originally going to buy red, black and silver Solartex and then I would need matching colours. In the end I bought natural Solartex, but did not think to then change to a non solvent based paint. However, at least Solarlac still sets in low temperatures.

I’m allowed to work in the kitchen but it has to reach below single figure temperature

You could also blame the cat.

Hi Peter, weather here in the Uk has not been ideal for making paint cure properly has it?. I have been reading your posts regarding your ailerons and I think what you have done not only looks great but works too. The central hub that you have used is geared and i understand you were going down a belt driven route, but your fixed wires are much better. However, what is that central hub from, ie where can i source a pair here in the UK.

One other question, epoxy board, where can i get some from, my local model shop drew a blank.

Many thank

Richard,

Missed your post having been away a few days. The hubs I used for the ailerons were originally grooved pulleys for small drive belts, but when I decided to go with the wires rather than belts I put the pulleys in my lathe and machined them smooth. I also did this because once I got the system working, the pulleys were a little too large diameter and I did not get enough throw on the ailerons, so by machining them down I got more rotation for the same linear movement in the control wires. A couple of photos show the pulleys before being machined.

I do not have any of the after machining and I have just covered the wings so no joy getting one now. However, if you go to Manish's build log on RC India, I made up the same set for him and he has a nice photo in post No 293, see link (Manish's Moth Build) or possibly the photo itself (Manish's aileron drive)

I am UK based and I tend to use ebay for all my odds and ends, the pulleys used for the aileron drive were the same model as these, (Belt drive pulley). Epoxy board is often called G10 board, here is one ebay item but there are many to be found (Epoxy glass board).

 

Peter.

There has been some progress on the build, most of my time has been spent putting on the rib stitching and pinked tapes over the rib stitching along with perimeter tapes etc. This appears to take an inordinate amount of time, this follows the same method as for the tail planes described earlier on page 16. I have also been busy with the fuselage, the undercarriage has been painted and reassembled, wheel covers have had the logo painted. I have added the lettering to the fuselage, the smaller lettering has all been cut from vinyl, as I have noted previously, my wife has a small CNC cutter for her crafting hobby, which has now been annexed. For the registration lettering, which would not look good in vinyl, I have cut paint masks on her cutter and used these.

Your painting and lettering is looking very smart

Things are coming together nicely on the fuselage. There has been more painting of the cabane structure and fuel tank along with various details such as the tops of the doors etc. I have rebuilt the fuselage back to where it was before covering and painting, except this time all the nuts and bolts have thread lock on them. There are still many many details to add such as the venturis, magneto switches, luggage door clasps, leather patches over the control wire exit holes, some decals still need adding, etc. I have to admit to one slight error, the inspection rings and patches on the tail plane and elevator should have been on the underside.

This is a club members Tiger Moth at last Thursdays’ club meeting . Flair kit, it was built about 20 years ago but never completed or covered by the previous owner. Powered by , as yet unrun , TorquePro 70 fs petrol.

PeterF, how was your Solarlac applied ?

Cymaz, I have brushed it on using some high quality wide brushes after thinning it down a little. The finish has come out well but not perfect. I do not have spray facilities. I believe I have got away with this because of the low ambient temperatures, hence the solvent has not flashed off too quickly whilst applying it.In retrospect, I should have used a non solvent type paint as I did not need to match coloured Solartex.

That is a nice looking Tiger Moth and it is always good to get a model completed. As you said it was 20 years old I was initially wondering about needing to check the soundness of the glued joints, but as it had not been covered, then that was easy to do. The one odd sight to me having built the Falcon Models kit, is seeing self supporting wings without the inter plane struts or wires, the Falcon Models kit will not do this as the wing attachments are engineered as per the full scale and the struts and wires are completely functional and absolutely necessary.

Well, the wings stripped down very quickly prior to covering, getting them ready to put back together is another story entirely. I have painted the wings and that went quite quickly, but I have had to clean up all the metal fittings as they had started to go rusty and paint them, paint the interplane struts, paint the covers for the slat mechanisms, cut some holes into the slats that I had missed, do some decals for the fuselage, cut discs for the aileron actuation mechanism and dummy aileron gearbox covers. It seems as though progress has stalled in terms of reassembly. However, in a few days time I am sure it will suddenly come together. I now have 2 weeks prior to my clubs show night and I want it ready. It will not be complete as a lot of scale detail will be missing, but the kit ex Falcon Models will be complete I hope.
