  1. On closer inspection after the tyre had been removed you could see a very small slash, no more than 5mm across but looks like it was caused by a flint. Hey ho, new tyre fitted and all is good apart from a lighter wallet.
  2. Video of the build
  3. Great stuff Richard, looking forward to getting my hands on one!
  4. Reduce the amount of elevator control and make sure CG is correct.
  5. My pilot, Hans Free, is about 1/8th scale and could be a tad larger as he really should fill the space a bit more. If you look at any photos or footage of pilots in the FW, there isn't a lot of room in the cockpit!

    Launch Dolly

    Following the build of the WR FW190 and the build of the launch dolly for it, I've been asked if I would make some of these for sale, so here it is. The following photos show the prototype for which I used C/F tubes but the production version has plastic (electric conduit) tubes instead. The frame measures approx 600mm x 600mm but the fittings can be positioned to suit the model it will be used for, in fact if you use screws to attach the fittings it can be adjustable to suit a range of models. There are 2 options for purchase, one with wheels and the other without as there are those who may have a stash of old wheels that could be used. If supplied with wheels the fronts are 6" dia and the rear 3". The foam support pads are included and the rear one is left ready for you to form a cut out to suit your model. The 3D printed parts are ASA so they should be OK for all weathers! Note that the following photo doesn't have the front nose support but that is in the kits plus it uses C/F tubes for the frame whereas the kits have white plastic tubes. The 3D printed parts Prices (inc UK P&P) as follows: Kit 1 - £45 Plastic tube 600mm x 2 Front wheels 6" x 2 Rear wheel 3" x 1 Front wheel bracket / wing supports with foam pads x 2 Rear wheel bracket / tail support with foam pad x 1 Front nose support with foam pad x 1 Fittings - nuts and bolts for wheel axles and wheel spacers. Kit 2 - £30 As above less wheels and fittings.
  7. For those who are still building or haven’t started yet I would strongly recommend strengthening the motor mount plate. I thought mine was split but it turned out that it just flexes a hell of a lot! I’ve now applied, with difficulty, some carbon tow to the back of it and into the fuse sides and the improvement is amazing. If I was building it again I would double the thickness of that plate.
  8. Chapter 1 - it has to start somewhere
  9. Well done Chris, look forward to seeing it in the flesh soon.
  10. Good man Peter, we’ll then have 4 at the field!
  11. As promised, the build or should I say restart of the build has taken place and videos will soon follow. I'm probably going to have fewer than my VLOG of the WR FW190 mainly because that one was primarily aimed at building newbies whereas this one is pure self indulgence! I stopped the build last year, can't remember why, but I had assembled a large part of the fuselage and had built the framework for the tail feathers so this VLOG will pick up from where I left off. Now those who have followed my YouTube channel will know that my intention is to power the Mystic with an old Laser 150 V twin which, to be honest, has seen very little running time and it will be mounted upright with the pots in the air. Why am I doing it this way? well it's because I want to have a bit of a Mad Max theme to it, so not only will the pots be upright I am planning to run the exhausts through 2 alloy tubes running down the length of the fuselage, a bit like some of the SE5a had, and maybe even terminating them with fish tail ends. The cockpit may well be open rather than the fully enclosed one provided in the kit and the wire U/C will be replaced by a Carbon Copy straight leg version. Now this is maybe the reason why I stopped the build last year because I couldn't decide on the U/C and in order to mount the CC one it will need a ply mounting plate but that can't go in until the fuel tank is in place the position of which is determined by the location of the engine! Fortunately the Laser's dislike to fuel tanks mounted too high won't be an issue here! So that is where I am at the moment, I've just ordered the U/C so hopefully Stuart can get that to me within the next week but in the meantime I'm busy sheeting the tail feathers, that work being the subject of the first vid. Watch this space.
  12. Back to square one, the guy who wanted it has backed out!
  13. That’ll be a 20x20 then I suppose?
  14. That’s a big one Eric 🤔
  15. I would suggest starting off with it at 80mm and then see how it feels.
  16. With the Overlander 3548 900Kv motor I'm swinging a 12x8 prop and that gives it nearly 2:1 power to weight ratio and provides it with unlimited vertical. Going bigger will increase the chances of prop breakage on landings.
  17. Glad you mentioned that, I’ve now removed 2/3rds of the weight which moves the CG back to 90 mm back from F2 but I think I can remove all of the weight which will move it back to approximately 100mm back.
