cymaz Posted January 11, 2015 Share Posted January 11, 2015 Can I suggest a small ply/plastic washer around the wing incidence pegs to stop the holes becoming oval? Quote Link to comment Share on other sites More sharing options...

Tim Hooper Posted January 11, 2015 Author Share Posted January 11, 2015 Turning to the fuselage top deck I've added subformers, a floor for the front hatch and a 1/16 x 3/16 spine. The deck is covered in 1/32 sheet. I made card patterns to determine the shapre before committing any precious balsa! Here's the front piece glued to the spine along it's centreline prior to bending the sides down. The rear piece has to cope with quite a tight curve at the rear end, so I dampened it with water first. No problems. The compound curve in the 'cockpit' area is fashioned from hollowed block, and the front cowl from a mixture of sheet and block. Lots of filler needed here! Here's the hatch removed. It has to be this long to allow access to the aileron servo leads, and the retaining clip for the wings. Magnets hold the hatch in place. ........and that's it for this weekend!

Peter Miller Posted January 12, 2015 Share Posted January 12, 2015 Hi TIm. Very interesting and impressive. I bet that would go well with a Cox TD .020, or even an .010!! It would also weigh even less. Quote Link to comment Share on other sites More sharing options...

Tim Hooper Posted January 16, 2015 Author Share Posted January 16, 2015 Peter, I thought about the little Cox, but it would scare the wildlife for miles around! More progress, in that I pinned the airframe together to check on the general proportions. Not too bad, although the wing does look a little over-sized. A quick check on the CG showed that the fuselage servos need to go in the rear fuselage, so I've cut mounts to suit. Anyway, I rooted in the Gubbins Drawer and fished out some scraps of Solite. The colours suggested a retro feel.... Quote Link to comment Share on other sites More sharing options...

Peter Miller Posted January 17, 2015 Share Posted January 17, 2015 I see thatb you are like me, \Tim. If you see a clamp you buy, beg, borrow or aquire it. Haven't see two of those that you are using. Quote Link to comment Share on other sites More sharing options...
Tim Hooper Posted January 18, 2015 Author Share Posted January 18, 2015 Peter, I'm a regular gannet when it comes to clamps! Anyway, it's finished! AUW is 180 grammes (6.3oz) - a little more that I hoped, but probably due to that hefty (45g) battery. That gives a loading of 10.1 oz/ft, so it's going to need a fair airspeed to keep it aloft. I've run the motor up on the Watt meter, and on a 4x4 prop it's drawing 46 watts. The pins in the tip plates are the easiest way to bablance the model. The aileron linkage. Just a piece of bent wire with a short length of servo wire insulation as keepers. The motor from beneath. The big battery means that the fuselage servos have to live in the tail. You can just see the 'keepers' that allow quick disconnection when the tail surfaces are removed. The hatch removes to give easy access to the 3S 450 pack - held in with a touch of velcro. Okay, now it's a matter of waiting for suitable weather to see if it flies. Only then will I think about making a box for it! Thing is, we're going to be very busy over the next few weeks. We're moving house, so there's a lot of work to be done. tim Quote Link to comment Share on other sites More sharing options...
Nev Posted January 18, 2015 Share Posted January 18, 2015 Look great Tim I will have to make one just for fun. If you make the box now you can keep it in the boot of the car just in case and get on with the house move. Anybody would think you had almost planned it that way Quote Link to comment Share on other sites More sharing options...
Tim Hooper Posted February 15, 2015 Author Share Posted February 15, 2015 We're back! House move done and dusted, and first time to the field since Christmas - wahaaaaay! So the Boxing Clever had it's maiden flight in the dull, but calm, conditions this afternoon. No probs. No drama. The model is pretty rapid - much quicker that I thought it would be. MInd you, the 4x4 prop might be a little deep for it, so I'll experiment with something a little shallower in pitch. So it loops, rolls, stall turns, does inverted, etc. I didn't push it too far, but it asll looks very promising. tim Quote Link to comment Share on other sites More sharing options...

cymaz Posted February 16, 2015 Share Posted February 16, 2015 Are the bends in the push rods there to allow some shortening/ lengthening ? Quote Link to comment Share on other sites More sharing options...
trebor Posted February 16, 2015 Share Posted February 16, 2015 I've seen a lot of indoor / park fly planes with wire bends for adjustments. Quote Link to comment Share on other sites More sharing options...
Tim Hooper Posted March 2, 2015 Author Share Posted March 2, 2015 cymaz, Sorry for the tardy reply, but yes, the bends allow for easy adjustment of the control surfaces. I thought it was about time that I did something about the 'Boxing' part of the model's name, so I made a ply box measuring 500 x 150 x 100 mm, then fitted it out with foam cradles. Here's the parts of the airframe as they fit within the box. The foam cradles CA'd in place. The model trying out its new home. I've fitted a hinged lid to finish the job off!

onetenor Posted April 17, 2015 Share Posted April 17, 2015 A length of largish cardboard tube would hold it Try carpet shops for the tubing. End caps for the tube are available on line. An I.C. conversion would be good with a cox 010 or 020 in front or a DC Bambi Following with interest John Quote Link to comment Share on other sites More sharing options...
