Simon Chaddock Posted March 15 Share Posted March 15 shepeiro Looking good. Still find it hard to believe it will come out to sub 60g. I would not worry about the extra resistance due to extending the battery to Rx wire. It is not as if it will be carrying a huge current. It is normally poor contact in connectors than generate electrical resistance. Quote Link to comment Share on other sites More sharing options...
shepeiro Posted March 15 Author Share Posted March 15 I have same worries tbh but so far weights have come out close to calculated. current weight of fuselage and wheel is 8.5g. tail feathers was 2, wings were around 2 each if I remember so we’re at around the 15g mark electronics we’re about 23g covering say 2g so we’re at the 40g mark. But we have at least 5g of stuff still to come So don’t think it will come out at calculated weight of 45g but think I should fairly easily hit 50g which will still be 10g under donor weight. the 2mm strips of ply are surprisingly light which most of the frame is down to thickening to 3mm around joints to help the slots hold rigidly enough to give it enough accuracy. again think glue is the biggest unknown. Think I could have lightened the fuselage by using thinned wood glue instead of CA esp as I’ve run out of good tips so was a little on the heavy side in places. Now the frame is rigid though rest will be white glue. 1 Quote Link to comment Share on other sites More sharing options...
shepeiro Posted March 16 Author Share Posted March 16 Some progress lots of little jobs (everything’s little on this) wings and tail feathers are all sanded and ready for putting together. Need to decide on colours befor I can progress with that though!!! Quote Link to comment Share on other sites More sharing options...
shepeiro Posted March 16 Author Share Posted March 16 Currently sitting at just under 14g Quote Link to comment Share on other sites More sharing options...
shepeiro Posted March 16 Author Share Posted March 16 Mixed news tonight though. Build coming on, paused putting stuff together to do a dry run of the electronics positioning. Going to have to do some alterations to the internals but nothing too bad. Worse was when I plugged in servo to see which direction it needed to be in to make sure it’s not inverted (won’t be able to flip with tx) the servo arm just kept spinning! Will need to rectify this before I can go much further unfortunately. Anyone have any idea! Never had this happen before Quote Link to comment Share on other sites More sharing options...
shepeiro Posted March 16 Author Share Posted March 16 Otherwise starting to look ship shape Quote Link to comment Share on other sites More sharing options...
shepeiro Posted March 16 Author Share Posted March 16 Took servo apart all the gearing is fine including the pentonemeter whotsit seems to be connected in properly. What I did notice was that it occasionally worked as it should when the connecting wire was in certain positions so think there is some connection issue though I couldnt see anything further. slightly worried that it may be a signal issue from the rx but this is only system I have that uses the five wires servos so can’t test that theory. have bought new servo off Ali express so will find out in 9-16 days 😞 Quote Link to comment Share on other sites More sharing options...
shepeiro Posted March 18 Author Share Posted March 18 Wings are on, nacelles frames on wing all looking fairly true so far. 1 Quote Link to comment Share on other sites More sharing options...
shepeiro Posted Tuesday at 23:00 Author Share Posted Tuesday at 23:00 Dry run with electronics. servo started working. No idea why not sure if I trust it. all the wires stretch just about but think I want to raise the rx up off the floor a little so it’s bang on the cg 1 Quote Link to comment Share on other sites More sharing options...
shepeiro Posted Tuesday at 23:20 Author Share Posted Tuesday at 23:20 @Simon Chaddock it’s currently at 40g! 0.5g of props a carbon rod and a few bits of wire for the elevator control might be another g rest of the stringers another 0.5g perhaps and covering 2g. Might get in just under 45g. Quote Link to comment Share on other sites More sharing options...
shepeiro Posted Tuesday at 23:31 Author Share Posted Tuesday at 23:31 Might even add the led light bars at 1g extra. Not quite sure where I would put them though Quote Link to comment Share on other sites More sharing options...
shepeiro Posted 9 hours ago Author Share Posted 9 hours ago Motor nacelles “planked” Quote Link to comment Share on other sites More sharing options...
Simon Chaddock Posted 8 hours ago Share Posted 8 hours ago Well done! Those nacelles are very neat. I like the temporary(?) struts to hold the planking in place. Quote Link to comment Share on other sites More sharing options...
shepeiro Posted 6 hours ago Author Share Posted 6 hours ago Cheated as I unfolded the form in 3d and laser cut the result. meant I could wrap the center section around the formers and then just tack the ends with Ca so was quite quick. May try this technique on larger models. temporary struts are my wife’s dress pins (need to get my own) Quote Link to comment Share on other sites More sharing options...
shepeiro Posted 6 hours ago Author Share Posted 6 hours ago Filleted, sanded and shaped might need a small amount of filler Quote Link to comment Share on other sites More sharing options...
