Thank you.

Can somebody please explain what Open TX and Edge TX mean and what the difference is between the two?

I'm with Stuart. I dislike installing the radio but I also dislike hinging the control surfaces. I have a DB Sport & Scale Auster which was given to me at least ten years ago, it only needs the canopy glazing to be fitted and the radio installing and it's ready for its maiden flight. I also have a Galaxy Models Mystic in the same condition which I bought as a quick build project four years ago! A club colleague has made an excellent job of spraying the Auster's cowling and Carbon Copy are sending me a white fibre glass undercarriage for the Mysic. When it arrives I'll have no excuses!

I asked the same question on "Glow Nation," on a well-known social media site. My post has been moved "lower in the feed" because it appears to incite violence! I promise you that I am not making this up! Big Brother is indeed watching you. "We moved one of your posts lower in Feed.

Good Morning EGB! Just Engines offer a range of silencers, either standard or "quiet," which will suit your engine. In order to be sure, just measure the distance between centres of the mounting holes, dimesion "c" on the drawing. They claim that their silencers with 35mm between the bolt holes will fit an OS engine which has 35.5 mm spacing. https://www.justengines.co.uk/product-category/exhaust-systems/two-stroke-exhausts/standard-mufflers/?v=11aedd0e4327 A range of special exhausts is available to order from Weston UK. I had one made for an SC 32 and it is very impressive though they are more expensive than a standard silencer. https://www.westonuk.co.uk/Genesis-Pipes/

A friend had one of the RCV CDs in a Puppeteer. It was quite reliable and flew the Puppeteer well enough but I've heard that these engines are not very powerful compared with poppet valve four-strokes and I can't remember what size it was. A Puppeteer would fly very well on an OS 48. I own three HP VT four-strokes which I really ought to sell. These use a disc valve for the intake and exhaust function. They certainly lack power compared with a poppet valve four-stroke.

I concur with all of the advice proffered so far. Nearly all of my models are fitted with four stroke engines and you won't go wrong with an OS or Saito engine but I've also had good service from engines produced by Thunder Tiger ASP, SC and Magnum. These manufacturers no longer make engines though I've had no problem finding spares for them. Then there's Laser of course...

I take it that the knurled knob controls the low speed fuel supply while the hockey stick needle with brass locknut is the main jet. Am I right?

Welcome to the forum Tony. Are you any relation to Ben Buckle?

Isn't AGC closing its doors too?

Traditionally the advice was that a four stroke should be 30%-50% larger than the recommended two stroke, so your Saito 49 should power adequately any model for which a 25-35 two stroke is recommended. Assuming that you do not want another trainer your Saito would certainly power a Barnstormer 63 maybe even the Barnstormer 72 from the DB Sport & Scale Plan Pack range or if you'd prefer a complete kit and something more sporty, the Galaxy Models Magician would be ideal. All of that said, I have seen a 40 four stroke power a Radio Queen, but then you'll already have a vintage model once you've built the Super 60!

The Ben Buckle Super 60 is a fine trainer and will suit the PAW. I've built two and bought another ready made. They are available as both three and four channel models., i.e, both with and without ailerons. They are fine trainers capable of handling a bit of a breeze. https://www.benbucklevintage.com/index.php?main_page=index&cPath=1_4 They are easy to build but if you've never built a stick and tissue style model before you'd be better off having the help of an experienced aeromodeller alongside you at least in the initial stages. On my latest build I have used De Luxe Materials Super Phatic glue for the first time and I can recommend it unreservedly. Pictures of my old Super 60s below.

Both the OS 40 Surpass and the little 25 are good quality engines so you should get a reasonable price for them. The other engine, if it is an FP, will command a lower price. My advice would be to take the model over to the nearest club where an experienced aeromodeller could remove the cowling and identify the engine.
