Yup... might want to move the square piece away from the elevator first. Â How much kerf does the laser make Ron? Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted September 19, 2023 Share Posted September 19, 2023 TBH with a cut that is <0.1mm I don’t bother with kerf, especially on 6mm Depron! Quote Link to comment Share on other sites More sharing options...

Ron Gray Posted September 19, 2023 Share Posted September 19, 2023 The build was finished last night   I don't know how well it will fly (it's based on the power train from the Hanky Planky) so I haven't bothered to cover it with lam film or brown paper but it has to have some paint on it so on with the mist base coat  Quote Link to comment Share on other sites More sharing options...
Daren Cogdon Posted September 19, 2023 Author Share Posted September 19, 2023 Looking good, though!   My French is extremely rusty/non-existent, but I take it that you glue the wing permanently to the fuselage and have a hatch on top of the fuselage?  Quote Link to comment Share on other sites More sharing options...
dave parnham Posted September 19, 2023 Share Posted September 19, 2023 (edited) do you cover these Ron? or paint the foam? Ok just re-read it and painted with a mist coat first Edited September 19, 2023 by dave parnham Quote Link to comment Share on other sites More sharing options...

Graham Davies 3 Posted September 19, 2023 Share Posted September 19, 2023 So, to contribute...  This is a 'one week from cause to effect' project  I dumb-thumbed the little Yak I bought from a clubmate. It flew brilliantly and encouraged me to practice the things I'm not so good at, and it ended badly when I lost which way up it was. It ended up tent-pegged, and these lightweight ARTFs are certainly not built to repair. So, BUILD A NEW ONE!  Crash was wednesday. Thursday was spent in a moving, private mourning ceremony. It was emotional.. Started on Friday, 1 1/2 hours. 1 hour on saturday and then a good day at it one Sunday. One hour this evening and this is where we're at. Not much more to do; maybe an hour before painting and finishing.  It's made from the black 6mm laminate flooring underlay from B&Q, with a bit of 3mm white (Diall) stuff for the curved parts of the fuselage. A few bits of lightply, 1/32" ply and a couply of carbon strips from a recently retired foam 3D indoor thingy, and coffee stirrers to stiffen the ailerons etc. Cowl is a lump of polystyrene, glued to a lightply disc, and spun until it was roughly the right shape. The top hatch is a lump of polystyrene onto a lightply base sanded to shape. I've been able to salvage a little bit of the canopy, so it's not far off.  I'm not going to cover it. I'll mist coat it in white emulsion, and then spray an emulsion colour scheme before a thin coat or two of water based varnish to give it some gloss.  Not weighed it yet, but the original is very light, and this is lighter!  The elevators, rudder and ailerons are not fitted in the pics as the stiffeners are still drying. The poor broken body of the original is there out of respect...  Graham   4 Quote Link to comment Share on other sites More sharing options...
Colin Carpenter Posted September 19, 2023 Share Posted September 19, 2023 I had one of those Yaks. Liked it ! Until one winter’s morning the fog crept up behind and to the side of me. I hadn’t noticed until I flew into it , and that was that 🔥🔥. It looked worse than yours !😂😂😂😩😩😩Colin Quote Link to comment Share on other sites More sharing options...
SIMON CRAGG Posted September 20, 2023 Share Posted September 20, 2023 Several Winter projects:  1. Sell "Big Fun" model which has been our club model this year. 2.Buy suitable Edge / Yak / Extra (hopefully second hand), that I can fettle ready for next years comps. 3. Collect just purchased Radio Queen (£30), and sort it out as a club trainer.  Always something to do!. Quote Link to comment Share on other sites More sharing options...
GrumpyGnome Posted September 20, 2023 Share Posted September 20, 2023 Always something to do...... my list this winter is: Â Fix the Ruckus that lost an argument with a tree Finish refurbing the Spitfire donated by a club mate Finish re-covering my little leccy SE5 (seems to be a recurring winter fix, this plane) Recommission my Yak54 Fix the warped wing and manky rudder hinge on my Rocky Finish my Sig Miniplane Sell some of the engines that I'm never going to use..... maybe. Â Doubt I'll manage all that as it gets cold in my Pigeon Coop (workshop)! Â Quote Link to comment Share on other sites More sharing options...
leccyflyer Posted September 20, 2023 Share Posted September 20, 2023 Hadn't realised this was a thread for listing winter projects, thought it was just Daren's forthcoming depron creations.  I've got two immediate smallish projects that I've commited to on RCG's MAGMAN build up, which is based on building from Aeromodeller or RCM&E plans from >50 years ago before the end of the year.  First one that I made a start on proper yesterday is Les Rudd's Go-Jet, as I was so impressed with Mark Dean's example at the Pontefract single channel day in July. Had started cutting out wingribs a while back, but in a rare example of workshop discipline I'd said I wouldn't start until my diesel powered Outlaw was finished, which it almost is. Most of the Go-Jet bits are now cut out and I've started the assembly, fitting the implausibly thick fuselage formers.   Second project is a build of an April 1973 Aeromodeller plan Jay-Pee, which I intend to have another try at control line, since I built one in the 70's, with rather limited success due to my signature control line manouver of a spirited wingover into the ground. That'll wait until after the Go-Jet is done.  Other projects waiting in the wings are the Wagtail, originally designed for Galloping Ghost, my Keil Kraft Mini Super and I also really need to pick one of my WR warbird kits and get on with that.   1 Quote Link to comment Share on other sites More sharing options...

I have a long list of thise I could drop a few into such a format, which I found a fantastic motivation that winter. Quote Link to comment Share on other sites More sharing options...
leccyflyer Posted September 20, 2023 Share Posted September 20, 2023 Belay my last pipe - I see that the original 2021 Dark Night's Fix Up thread has been retitledas the Annual Dark Night's Fix Up thread, so if fit for purpose as it stands. I'll have to update the subsequent progress on my Beufighter, which had stopped once I launched into my current vintage obsession. 🙂 1 Quote Link to comment Share on other sites More sharing options...
