I am looking for a starboard aileron as a strategic spare. My outboard hinge pin is beginning to click and sooner or later it will have to be replaced.

I got to wondering if we under value our Vintage Pipers in the UK.
Looking at Trade-A-Plane you will find PA-18’s offered at prices up to $170,000, and there are certainly plenty at over $100,000 yet few owners in UK would consider their aircraft to be worth £60,000.
The value of PA22s are even less, yet a Tri-Pacer will take two adults and two children into most places that you can take a Super Cub. Why are they less valued?
The guy who rebuilt my Super Pacer G-BSED told me he sold it for £51,000 which is not unrealistic for an aircraft which has been re-covered, has a good engine and avionics and a new interior, yet some owners will say that they would struggle to get £25,000 for their aircraft.
What do others think ?

Subject: DATA PLATE ON 1946 J3C-65
I would very much like any information on DATA PLATE for the CUB.
Any photos from members of plates in their cubs and what should be in the spaces on the plate would be appreciated.
Are they engraved or stamped in? What needs to be in the engine space even if the engine has being changed to a 0-200.
Any information will be appreciated.
As reported on the List last week many of the premium grades of mogas fuel are now compliant with British Standard EN228 and therefore are useable in cleared aircraft/engine combinations as detailed in the CAA document GC5 in CAP747 providing that the fuel doesn’t contain alcohol (ethanol). Not only that, unlike the regular grades of unleaded mogas, over much of the country the premium grades do not contain alcohol. However, it remains the user’s responsibility to test for the presence of alcohol before any mogas is used in aircraft and there are kits commercially available to do just this. Some of these kits consist of a test bottle that contains a small quantity of dye, the dye dissolving and colouring any fuel sample that does have alcohol present. The problem with this is that following any positive result the bottle cannot be re-used. I’ve often wondered, no doubt like many others have, what the dye is so that I could make my own test kit and I seem to have found an answer to this question. Just an case you think me some sort of a research chemist I can assure you that I’m not…I got the clue to this from across the Atlantic via the Internet!
Sooo, in a couple of words the answer is food dye….it’s a simple as that. The dye will dissolve and discolour fuel that contains alcohol, but it will stay separate if the fuel is free of alcohol as shown in the photos that I have just taken. The sample jar on the left contains fuel that is alcohol-free and that on the right does contain alcohol (it’s regular mogas destined for use in the lawn-mower). Therefore, my DIY alcohol testing kit is simply a jar that contains a small quantity (a few small drops) of bright food dye and before I commit to buying a tank-load of mogas I will add a small sample of the fuel to my jar. Should the sample stay clear with the dye remaining on the bottom as separate globules then the fuel is alcohol-free, but if the sample turns green then it does contain alcohol and cannot be used in an aircraft. The only question now remaining is how much does the food dye cost and I must admit that I don’t know the answer to this one, but one thing is for sure, it is definitely a whole lot cheaper than the cost of an official aviation fuel testing kit! (Well…I was born in Yorkshire) and it is much more practical than performing the “water in a tube” test. I hope that you find this useful.
P.S. Considering the hassle of using mogas/jerry cans etc compared with the ease of avgas straight from the airfield’s pump I did a few sums. For an aircraft that flies 100 hours a year burning 25 litres per hour the cost saving made by using premium mogas at £140.9/ ltr compared with a very “inexpensive” avgas at £1.81/ ltr is in the order £1000 per annum. Makes you think!
The L18C I’ve purchased now appears to have a very tired engine.
It’s has a C90 at the moment and I’ve been told the crank is difficult to source. I’ve been quoted a ridiculous amount to rebuild it.
The numbers are close to a new 0200 lightweight.
Does anyone have or know of a reasonably priced good engine, either a C90 or O200.
