I'm in a time warp, it doesn't seem as though so much time has passed since I last posted on the topic. Not a lot has been going on, apart from wasted hours looking for bits that HK advertise until you go to buy them, then they are "backorder". However its not all doom and gloom, thank goodness for home based suppliers, it took me a couple of days spending an hour or so looking for bits and pieces, but at last I've had confirmation that everything I bought is now on its way. I made a mistake last year when I sold practically every flyable model, I should have kept at least one, and I sold all my engines too, apart from the OS FS .52 which is going to power the Kadet, and a couple of pristine MDS .17s which nobody wants. Today I've been tinkering with an OS FS .70 Surpass, bought on eBay as a known "non-runner". The photo of the engine showed it had a big dent in one pushrod tube, and the profile of the pushrod could be seen at the bottom of the dent. The seller suggested a price and asked for offers, I made one, and almost had my arm torn off by the enthusiastic response. There were two problems with the engine, the dented pushrod cover was a doddle to fix with a small hammer and a short length of silver steel, what took a bit of time was the seized exhaust rocker arm (not mentioned in the eBay description). This finally succumbed to a warm up from my butane torch and a good wiggling with a pair of pliers and a generous slurp of oil. The OS .70 now has the obligatory "suck-squeeze-bang!-blow" sequence, in fact the compression is so good its almost impossible to turn over without a prop fitted. I haven't been ignoring the Kadet, from time to time I've been sanding it with 400 paper ready for the first coat of sanding sealer. I don't know if Solarfilm/tex was invented when the Kadet first hit the market, perhaps I ought to do a bit of searching. I was considering a tissue/dope finish, with doped on contrasting tissue trims. I've a big piece of SIG Koverall, which is a bit fiddly to seal with dope, and I've an even bigger piece of "Polyspan" which looks like old fashioned rag tissue, but is a good deal stronger, might go for it as its easier to dope with a brush.
