I never built anything as Basic as your Control line Plane there. It would be a little boring wouldn't it?  Grass a bit long in places. Nev

Yes, you've enjoyed telling me that a couple of times now. It's a 1/2a speed model. 049. KISS baby, KISS.

I don't Know if I've ENJOYED saying what I have , I've never seen an engine of that size used in control line .  We considered the control lines  would have too much drag. I'm interested. Don't take it as a "snob" thing as it wasn't intended as such.. Nev

049 is the classic beginners engine. But for all the reasons you imagine, they really aren't great for beginners. The reason they were so popular is price. Personally, I think a .10 is a useful minimum size for CL. My first CL model as a kid was a .15. which I still have. You aren't wrong though, since this plane (which I built over 20 years ago) isn't aerobatic it's not exactly exciting 😄. I didn't even have any other propellers to tune it. I have some now.

If you think this plane is simple, wait until you see my current project 😄

 

We are doing a club 1/2a combat class. Made from one 3d printed mount, that I've reverse engineered (ie, stole the design) and one piece of core flute with a 3mm carbon fibre rod inserted. Took me about 1 hour to draw up and cut out 😀. Again 049. I believe the design isn't particularly aerobatic, but I've identified a few things I can improve. It has to be really simple, to get hands on handles. I just have to adjust the mount now because I didn't allow for shrinkage. Probably go about 2% larger. I'll post a pic when it's all done 🙂

This is actually the last model I built, about three years ago. I didn't go hard core with proper FAI rubber, just the rubber in the kit so it didn't fly far or long. Just as well, I was just using a football field. I would have lost it 😄

I have much better photos somewhere, but here's a screenshot shot from FB 🙂

OMG! This post brings back so many distant memeories, From running many miles to get a flyaway aircraft and cremating crashes of the day.

I still wear a bit of a scar where I got hit on the cheek bone just missing my eye with an aluminium spinner I did'nt see coming on a free flight model that was coming into land.

Yep, racing, landing, catching, refuelling, restarting and rejoining, then over taking or being overtaken, what fun, laughs and confusion, getting giddy; down at a local park.  Then the combat sorties.

I've been looking up a lot of the MODEL engines that were made.  VERY INTERESTING.  recommended. I still have a Bit of what I Had but collectors persuaded me to Part with quite a Few. You need to Look after them carefully. Not good tor Run Old ones as the metal can age Harden. I know a few KEEN collectors.. One sometimes comes to the Men's shed. His FATHER built Beaufort's at GAF. Drove a car till he was 100. His Father and I used to Have LONG discussions about aircraft design and Build quality. Nev

As promised, the beginner class 1/2a combat model made from core flute. The only part that is glued is the lead out guide. Engine mount is 3D printed and attached with three screws. 

 

I couldn't easily find a glow clip to suit Cox. On Lucky Lil 7 I just used alligator clips because that version is beam mounted so was easy to just clip onto an engine mount bolt. So I decided to channel the olden days and made one from a clothes peg 😊. Didn't have any handy sized wire kicking around so will finish it off during the week.

ALL the Little Motors I used were Diesels. I never had any Cox's.  Anything over  1.5 cc  was Glow Plug Usually 5 cc FROG 500. K&B.29 OS 29. ETA 19. McCOY 19.Testor corp( Piece of crap).  I've probably forgotten a few;  The OS 29 I still have with a lot of use It's STILL Good. Nev
