To clarify the situation, I have always been impatient, whether I was doing anything, going anywhere or just waiting for something to happen, doing a job i would keep going till it was finished .

Chris Walby Posted December 26, 2023 Share Posted December 26, 2023 Thanks for the quick and complete build there Eric. So in summary what's the things to look out for? Canopy fillet Additional balsa support Beef up the motor mount Rough the plastic parts before painting Set the elevator neutral and watch out as its a bit sensitive? Anything else rom memory? I won't be completing mine that fast for sure! I have a Tigercat to sort out... 1 Quote Link to comment Share on other sites More sharing options...
Eric Robson Posted December 26, 2023 Author Share Posted December 26, 2023 Pretty straightforward Chris, don't sand the elevators too thin as the joiner goes back quite away and I broke through when drilling mine, not enough to be a problem. Don't forget the doubler for F2, it can be retro fitted but it is easier put on before the cowl wrapper. Hopefully most people will study the template sheet, it is marked F2 bottom doubler but not shown on the plan. 2 Quote Link to comment Share on other sites More sharing options...

Gordon McConnell Posted December 26, 2023 Share Posted December 26, 2023 Eric, thanks for your feedback to all of us. Getting started on mine again and making progress on the fuselage. It’s really intuitive to put together, thanks to Richard. Only thought I have had is on the provision for the battery installation. The battery access panel fits perfectly between F1 and F2 with its spring loaded catch. Did you put any structure inside the cowl to support the battery? Gordon (not so speedy) 😀 Quote Link to comment Share on other sites More sharing options...
Eric Robson Posted December 26, 2023 Author Share Posted December 26, 2023 (edited) Gordon, I am using a 4s 3600 battery which fits diagonally from behind F1 to F2, it is a tight fit once the hatch is fitted and can't move. A smaller battery may need some restraint to stop the c of g movement. I have started adding some detail.

Eric Robson Posted December 27, 2023 Author Share Posted December 27, 2023 Another point worth noting is the dowel for the front of the wing. I drilled the hole after the wings were glued together with epoxy, this made it difficult to keep the drill in line. It may be better to either file a half groove in the wings before joining ad keep the epoxy away from the area then epoxy the dowel in after joining the wings . Meanwhile some more detail work. 4 1 Quote Link to comment Share on other sites More sharing options...

Yes Ron but someone building for the first time will want to use what's supplied and as the central hole is already in the former,may as well use it. Gone are the days when we could pop into the local model shop for bits and pieces. Side one completed now to do it all again. 1 Quote Link to comment Share on other sites More sharing options...

Bucksboy Posted December 27, 2023 Share Posted December 27, 2023 (edited) Eric, Could you please show a bit ore detail around the battery hatch please? I’m nearly at the same stage as Gordon, I’ve glued the two sides together but haven’t glued the big, circular formers F1 and F2 yet, they are dry fitted. I have the battery hatch cover with the pre drilled holes, it fits well. I’m just struggling to understand how the latch is fitted and which bits come off? As always, a picture speaks a thousand words so here is where I’m at. thanks! Edited December 27, 2023 by Bucksboy Forgot to add thanks.

Eric Robson Posted December 27, 2023 Author Share Posted December 27, 2023 Hi Bucksboy, I hope this helps, the catch is screwed to the underside of the plate with the screws provided. The plastic cover is trimmed to fit, you will find the most is trimmed from the front. I laid the vac formed cover for the guns in position after trimming it to fit, line the two pieces up with the notches in F2. I used Uhu glue to stick the vac forming to the hatch. 2 Quote Link to comment Share on other sites More sharing options...
mightypeesh Posted December 27, 2023 Share Posted December 27, 2023 Nice work with the oil pastels on the wings and tail feathers Eric, looks really great! thanks for posting details of build too. Cheers, Simon 1 Quote Link to comment Share on other sites More sharing options...

Thanks for your photos. They have answered almost all my unanswered questions after reading the first big thread. Definitely won’t need written instructions after all the information on these forums! 1 Quote Link to comment Share on other sites More sharing options...
Bucksboy Posted December 27, 2023 Share Posted December 27, 2023 Eric, Thank you for the explanation and photos, that clears it up nicely. My wings are glued together and I’ll leave them overnight, I’ll sand the LE tomorrow and then use the glass bandage to finish them off. Thanks again, very helpful. 1 Quote Link to comment Share on other sites More sharing options...

The best way that I have found over the years is to join the wings and apply bandage, When dry cut out the area where the dowel goes. get 1/2" balsa and drill hole for dowel and glue. insert into former, align wing and cut balsa length to fit cutout of wing and glue in to wing cutout. One big advantage to this method is that you get perfect alignment of wing in all axises. Plus you are creating a weak point that is easily repairable.

Gordon McConnell Posted December 28, 2023 Share Posted December 28, 2023 Graham R, thanks for sharing. I am going to try that method. I slightly re-inforced F2 with 1/8 inch ply, forward of the dowel hole as it seemed to be a possible weak point in a heavy landing. Probably unnecessary but then my landings can be very heavy!

Silver Wolf Posted December 28, 2023 Share Posted December 28, 2023 Eric thanks for getting the builds underway, nice to have a guide for the build and the hatch photos most welcome. 👍 1 Quote Link to comment Share on other sites More sharing options...
Eric Robson Posted December 30, 2023 Author Share Posted December 30, 2023 Just a point about the hatch it is a snug fit and has to be inserted into the slot at a slight angle, to get good fit I didn't glue the vac forming on and trimmed the cowl wrapper till it was a neat fit. I then used uhu glue on the sides of the hatch placing the vac cover on I slid it into position and left it to let the glue set. Be careful not to get the glue on the outside or the hatch will be very awkward to remove. Quote Link to comment Share on other sites More sharing options...

Another way is to cut away the foam at the l/e where you need the dowel and let in a lump of softish balsa, which is easy to drill and glue in the dowel. IIRC that was the method Precedent used to join the foam wings of the FunFly I built to pass my 'A' 25 years ago. Precedent also slotted the wings to accept a 3mm ply dihedral brace - a method I used to join the wings on my Mew Gull. 1 Quote Link to comment Share on other sites More sharing options...

leccyflyer Posted January 3 Share Posted January 3 That's excellent Eric - tracked nice and straight, good acceleration and the dolly departed the runway, ending up safely out of the way of other flyers. Nice one. 1 Quote Link to comment Share on other sites More sharing options...
