Steve W-O Posted January 2, 2012 Author Share Posted January 2, 2012 Posted by Biggles' Elder Brother - Moderator on 01/01/2012 13:20:45:25% is quite a weight saving - and probably for no significant strength compromise either! Must get/make myself a set of hole cutters. Where did you get yours from Steve? BEB PS Nice build work BTW! From Avicraft, but I have a problem with one, waiting to phone them. If you have access to a basic lathe, they are very easy to make, I used to make them for paper as mentioned. Quote Link to comment Share on other sites More sharing options...
Steve W-O Posted January 2, 2012 Author Share Posted January 2, 2012 Started on the tail, problem is, I don't know how I am going to make it I was going to have fully moving surfaces, but decided against it. The elevator is OK, but the rudder is going to be a bit on the small side. Fortunately it sits on a pedastal that fixes to the fuselage, so I can build it all on the pedastal first. The small fuselage next to it is the beginning of the Beguine. It is bigger on the ground than I thought Quote Link to comment Share on other sites More sharing options...
Steve W-O Posted January 3, 2012 Author Share Posted January 3, 2012 Didn't get much time yesterday, and tomorrow is back to work, but finished most of the tail section, more importantly worked out the mechanics of the linkages. Quote Link to comment Share on other sites More sharing options...
Biggles' Elder Brother - Moderator Posted January 3, 2012 Share Posted January 3, 2012 You're right the rudder is very small compared to the elevators isn't it. Mind you the tailplane is enormous! BEB Quote Link to comment Share on other sites More sharing options...
Steve W-O Posted January 3, 2012 Author Share Posted January 3, 2012 Yes, I should have said tail fin, as it was a fee flight model it only had a small trim tab for a rudder. I will give the rudder plenty of throw, if it is not enough, I can extend it up and back later. The tail plane is very big, but I wanted to keep the same overall proportions, so I left it as was. I have reduced the thickness a little, and given it less top camber, which means I may have to have some down trim in to hold the tail up, hard to try ans strike a balance between what was a free flight with to speed settings, engine full or engine off, with the variables of RC. After all, it will be more RC assisted then RC, if I am going to keep the proportions, like the tail size and the dihedral. It only really needs enough control to guide it in the right direction Quote Link to comment Share on other sites More sharing options...

I want an air intake in the top deck as well as under the motor, the basic shape is quite square, and I don't want to loose that look. I hope to have everything finished by the Easter holidays, the Linnet, the Beguine, Rainbow and the Cessna. No harm in dreaming Quote Link to comment Share on other sites More sharing options...
Steve W-O Posted January 22, 2012 Author Share Posted January 22, 2012 Nice big hatch done, access won't be a problem, and I won't have to turn it upside down or take the wings off to change battery, a pet hate. Quote Link to comment Share on other sites More sharing options...
Big Bandit Posted January 22, 2012 Share Posted January 22, 2012 Very neat Steve, I really like the fuselage shape and the way you've thought it through. Cheers, Chris. Quote Link to comment Share on other sites More sharing options...
Steve W-O Posted January 22, 2012 Author Share Posted January 22, 2012 Thanks Chris, I have done more thinking than building in the last couple of weeks (all that proves is that I must be a slow thinker ) I built the tail section knowing I did not want external control horns, and slowly added bits as the setup developed, but it was only on Friday I made the final decision on how to attach the rudder to the pushrod!The same with the fuselage, I knew what I wanted, but it has been a case of building and "designing" as I go I think I have kept most of the shape, the original of course was not enclosed on top at the front. My front windscreen pillars are different, to make it stronger when removing it. The basic outline is the same still though. Quote Link to comment Share on other sites More sharing options...
Steve W-O Posted February 25, 2012 Author Share Posted February 25, 2012 Well, at last it is beginning to near completion. Eventually decided to go ahead with the "hidden" controls on the fin and tail plane, ie no horns showing. Worked out better than I had thought at one time. I only have the radiator grill and a small panel in front of the fin (the whole tail assembly is separate to the fuselage), tighten the motor and secure the motor wires. Then there is the covering. I wish someone would invent spray on plastic film Quote Link to comment Share on other sites More sharing options...
Big Bandit Posted February 25, 2012 Share Posted February 25, 2012 That looks brilliant Steve, a very neat job and looking forward to the finished result. Cheers, Chris. Quote Link to comment Share on other sites More sharing options...
Steve W-O Posted April 21, 2012 Author Share Posted April 21, 2012 Well, after quite a few weeks of little motivation, I have got it almost finished. All that is left if to tidy up the covering on the tail assembly (it is still not fitted to the fuselage), the windows, pilot and instrument panel, and the radiator grill that goes just above the prop, That just want painting black, I want the front to look a bit more dated. The total weight including battery is 39 1/2 oz, so I am quite happy, it will have a duration of 15-25 minutes on a 2200mAh battery. I will prop it for more thrust when testing, then for duration after testing is complete. It will have thut to weight ratio of about .8 with the 2836 motor. This years build has gone much better, I am much happier with the results. and for comparison of what I was wanting it to look like Quote Link to comment Share on other sites More sharing options...
Alex Gibbs Posted April 21, 2012 Share Posted April 21, 2012 Hi Steve, just wondering... how did you cut the holes in the wood? they look so perfect haha Quote Link to comment Share on other sites More sharing options...

I will be rebuilding the tail section, not happy with the overall finish. It has no hinges as such, and all the controls are inside the fuselage, but although it works well, not possible to cover well and look good. I also have an idea I may need more rudder, so I am going to fly first, then rebuild and modify if needed. Quote Link to comment Share on other sites More sharing options...

Steve W-O Posted May 6, 2012 Author Share Posted May 6, 2012 Thanks. The engine sound is a bit corny, and badly done, but when faced with a choice of corny engine sounds and "they're coming to take me away ha ha" or the dambusters theme, I thought the poorly done engine sounds won When I first taxied it, I got to the shrubs, and it wouldn't turn! Picked it up, disconnected the battery and checked all the connections, rudder still wouldn't work. Couldn't think why the system would fail on one channel only. It does of course help to move the correct stick, only being three channel, I put the rudder where the ailerons would normally be. Moving the right hand stick seems to have fixed the problem!
