Having finished Wedgy I decided to have a go at another of my old planes in the loft. I think it was Mikes Premier Lion that got the blood flowing!.

I was going to build something completely new, after looking at the price of Balsa I decided on another Refurbishment.

Back in the 70's I use to get my RC magazines from the US and I was bitten by a cover picture of an Ohlsson pacemaker (see attached).

When originally built I put a PAW 19 RC in it, but it was always marginal on take off. Most of the time it had to be hand launched. Changing the engine would mean I would have to get a new spinner which I think I have now sourced from Traplet Publications, the Spinner Set for DH98 Mosquito.

I deliberated on the engine for ages and finally opted for the Enya 41-4C. Its more expensive than most but I always liked Enya's when I was flying a few years back.

The fuselage was looking pretty grim the Nylon and dope covering was looking pretty sorry for itself, the tail plane had some bad cracks in places. I bought some 1/4" carbon fibre strips and this really has strengthened the whole tail up.

The wing looks in remarkably good shape just some tip damage, but will need to be recovered the same as the fuselage. I was thinking of using Solartex but I'm not sure if you can add colour to this like litespan?

Any advice on modern coverings would be most welcome as I'm prolly out of touch these days.

Regards

Bob

Hi Bob
Solartex is a smashing covering to work with and gives a good finish especially to early scale models and vintage planes. The down side is the weight it adds, but that Enya should have plenty of power. It's fuel proof and can easily be painted.

Hello Bob . The Enya's are excellent engines .As you say a bit more expensive and heavier than some but last forever. used mainly ,I think by scale modellers similar to laser's . Only practical down side is that if they still have the glowplug at the front you will have to fit a remote glow lead as the prop spins dangerously close :shock:. Good underated engines.

Solartex can be easily painted .It doesn't take self adhesive trim as well as fiilm as it has a textured finish . Avoid dark colours as they can still slacken in hot sunshine.Some builders give the finished model a coat of dope as the y reckon it stops this but I dont think it does , it just ads weight and the dope discolours with age.

One thing to consider during refurbishing is the spar strenght in the wings . dont forget that free flight model will float with the air currents and have virtually no payload  but with radio assist or control you may wish to manouver the model and put a lot of strain on the wings . The added weight of battery and four stroke engine also add up quickly .Think about adding carbon tows to the spars or changing the spars to spruce .A lot stonger for very little added weight. Worth considering as wings have been known to fold:(

Thanks for that.

You know It completely passed me by the position of the glow plug :(

That explains why they included the plug extension lead with the engine.

I have been using carbon fibre on the tail to strengthen it up and I will be doing the same to the wing. Although I have always put ply wood dihedral braces in my planes and used epoxy to join them.

Well that's a result! After taking the nylon off the wing. I found I built it with 2 spars 1" x 1/4" and 3/4" x 1/4" spruce and 3/32" balsa wing ribs. I completely forgot about that, but after something like 25 years that's to be expected I suppose.
