EarlyBird Posted February 18, 2022 Author Share Posted February 18, 2022 Bottom sheeted and top brace added, 1/8" ply. Centre ribs, wing bolt thing, gussets and TE shear webs. Spar shear webs and top sheeting cut out. A busy day for me. ? Steve 2 Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted February 19, 2022 Author Share Posted February 19, 2022 Centre section sheeted. Nearly. The front will be done when the grabber plate is glued in which needs the fuselage finished for alignment to take place. Next fuselage or tail feathers a choice needs to be made. ☹️ ?

Peter Miller Posted February 19, 2022 Share Posted February 19, 2022 I gather that you are building the one with the bolt on wing. Quote Link to comment Share on other sites More sharing options...
kc Posted February 19, 2022 Share Posted February 19, 2022 (edited) Steve, I see that you will soon be making the parts that are 'stick' construction ( sticks as the americans say for strip constuction) so I wonder if you have seen the tips on this on Andy Gates Magister thread? In particular the link to PatMacs gadget might be worthwhile. I found Andy's comments very worth reading.

EarlyBird Posted February 20, 2022 Author Share Posted February 20, 2022 On with the tailplane. There are 1/8" square and sheet to add and shape, which can be done off the building board which frees it up for the fuselage. ? Steve Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted February 20, 2022 Author Share Posted February 20, 2022 Decision time, which I have been putting off. To keep the prop in the designed position puts the motor mount 30 mm in front of F2. Thinking as F2 is only half a former leave it in the design position and cut it down for a battery tray, steerable nose wheel mount. Which means making a 'coffin' motor mount battery tray, which I will look into. The motor shaft needs reversing unless it fits beneath the battery tray. This all means I can build the sides ? I forgot I need to decide where the tailplane will be located as my thinking is to move it up. Steve Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted February 20, 2022 Share Posted February 20, 2022 Cut the shaft off. Wrap the motor tightly in a plastic bag with the shaft through a tiny hole and using a Dremel cutting disc cut the shaft off short 1 Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted February 20, 2022 Author Share Posted February 20, 2022 A bigger motor, 3536, with a reversed shaft. We will see. Time to start building. Steve Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted February 20, 2022 Share Posted February 20, 2022 Move the tailplane up, make a full depth rudder. Quote Link to comment Share on other sites More sharing options...
kc Posted February 20, 2022 Share Posted February 20, 2022 Why move the tailplane up? Moving it up means one needs an elevator joiner ( I hate them! ) while if it's left low just a chamfer off the rudder ( or fuselage) clears the elevator on this model. A central pushrod could then be used for elevator for really positive control. Simple is better? Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted February 20, 2022 Share Posted February 20, 2022 To me it looks better K.C, it's glued in and no faffing with bands/bolts and you get a full depth rudder, positives all round. Quote Link to comment Share on other sites More sharing options...
PatMc Posted February 20, 2022 Share Posted February 20, 2022 I'd stick with the tailplane mounted below - & use a peg or ply tongue at the front with single 3mm screw fixing near the TE. No reason the tailplane position makes any difference to the rudder length, though I don't see the point in increasing it, it's more than adequate as is.

Peter Miller Posted February 20, 2022 Share Posted February 20, 2022 Quite frankly and looking at the dihedral the rudder is almost big enough. I am simply taking my rudder to the top of the fin and leaving the bottom alone. 1 Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted February 21, 2022 Author Share Posted February 21, 2022 Thanks guys, I will probably go with a combination of the above suggestions. At present take the rudder to the top of the fin and glue the tailplane in are more or less decided which just leaves the location of the tailplane. ?

EarlyBird Posted February 21, 2022 Author Share Posted February 21, 2022 Progress Just started the diagonals, not as easy as the uprights. The first three bays are infilled as shown on the plan so I was going to glue the frame then infill with the 3/16" balsa sheet but I thought I could glue the uprights to the sheets first then glue them in place. I have just checked my Super 60 and it's tailplane is glued to the bottom with full one piece elevator and pushrod in the centre of the fuselage, as kc described.

EarlyBird Posted February 21, 2022 Author Share Posted February 21, 2022 Diagonals done. Glue it all together next and make a decision on tailplane location. Steve Quote Link to comment Share on other sites More sharing options...
kc Posted February 21, 2022 Share Posted February 21, 2022 If you decide on low tailplane then you might as well build in a slight chamfer to the lower fuselage to enable maximum elevator movement. Quote Link to comment Share on other sites More sharing options...

I am starting to think I should build the tailplane low as the plan, easier that way as I don't have to make a decision. Tail dragger and steerable tail wheel also but that decision can wait.

EarlyBird Posted February 22, 2022 Author Share Posted February 22, 2022 Decision time on tailplane location and steerable tailwheel. How to connect the tailwheel to the rudder to make it steer? Moving the tailplane up then how to fit the elevator with the tail post in the way? Steve Quote Link to comment Share on other sites More sharing options...
