Tim Hooper Posted March 8, 2014 Author Share Posted March 8, 2014 Thanks guys! Although I made up the support structure for the all-flying tail some time ago, I've had a re-think and made some modifications. Firstly, the standard 3mm clevises have been ousted in favour of some more of those super heavy-duty items from SLEC. Not cheap at just over £3 each (and there are 6 of them), but a substantial improvement structurally . I've also cross-braced the lower support frame to prevent it from flexing. You'll also notice the glassfibre elevator horns are epoxied in place. The elevators are wiggled via modified snakes; there's a full length Bowden cable running through the inner snake, with soldered connectors at both ends. This is prevent trim changes caused by variations in the weather causing the snake to expand and contract.. Moving forwards, I've been sorting out the power supply for the radio. It's very similar to the set-up I use on the BUSA Nieuport, in that I'm having two power sources; The 10S flight pack runs 42v through to a UBEC which turns it into 6v. A back-up 3S pack which runs 12.6v to another UBEC. Both UBECs supply a backer unit which feeds from both UBECs normally. However if one supply fails then the other takes on the full load. This means that I shouldn't lose radio power - even if one of the cell packs bites the dust whilst in flight. The new refinement is this Turnigy unit, which separates the receiver from the servos, so that the power used by the servos does not travel through the receiver. Does it work? Dunno yet.......

Ton van Munsteren Posted March 8, 2014 Share Posted March 8, 2014 Tim, Don't know much to say, but just to let you know iam following this masterpiece build , great job and great pics as always. O just a small question how do you know both Ubec's are working , how do you check that before each flight. Ton Quote Link to comment Share on other sites More sharing options...
Tim Hooper Posted March 9, 2014 Author Share Posted March 9, 2014 Hi Ton! The UBECs and the Turnigy backer unit all feature LEDs to show they're functioning correctly. I'm mounting the whole lot in the rear cockpit, where it will be visible for inspection. tim Quote Link to comment Share on other sites More sharing options...

Tim Hooper Posted March 10, 2014 Author Share Posted March 10, 2014 Chris, I was aware that you were able to supply goodies to the inner circle of the Dawn Patrol, but I didn't realise that you'd be happy to deal with us lesser mortals too! I'll keep it noted........ tim Quote Link to comment Share on other sites More sharing options...
Tim Hooper Posted March 13, 2014 Author Share Posted March 13, 2014 I'm at the stage of doing all the minor, but incredibly time-consuming, little jobs that need to be done before I can even think about covering the fuselage. Anyway attention has turned to the motor box. Using a 7/8" bit, I've cross-drilled the battery box to let some air flow around the cell-packs. All well and good, but there's no obvious way for the air to get out of the cowl, except through the lower quadrant (below the battery box). So, I've contrived to make an airway through thelower cowl and into the fuselage itself (where the air can escape through the cockpit openings). Beneath the nose I've added a fairing from 1/32 ply, which features holes to allow the front rigging for the u/c to pass through. You can also see the ends of the brass/steel rigging plate that will hook up with drag wires from the wing tips - essential to stop the wings from folding backwards in flight! Not only that, but I've sheeted the belly with 1/8 sheet. Quote Link to comment Share on other sites More sharing options...

Biggles' Elder Brother - Moderator Posted March 13, 2014 Share Posted March 13, 2014 Yeap - lovely work. Just the sight of that "bank of ailerons" puts the frighteners on me! BEB Quote Link to comment Share on other sites More sharing options...
Tim Hooper Posted March 13, 2014 Author Share Posted March 13, 2014 Posted by Biggles' Elder Brother - Moderator on 13/03/2014 23:01:33: . Just the sight of that "bank of ailerons" puts the frighteners on me! BEB Thanks Gents! All your comments are truly appreciated! BEB, it all looks a bit intimidating, doesn't it? Just to ease myself into the correct mindset, last weekend I took my little 45" (Peter Rake) Tripehound to the field and had several flights. Just to prove to myself that these over-winged monsters actually fly! And fly it does! Yes, it's a tad sensitive to ailerons - that's what expo is for, yes? More un-nerving is its tendency to almost come to a dead halt in the air when full aileron is suddenly applied. Must be all that drag/adverse yaw..... Anyway, three flights and three noseovers. tim Quote Link to comment Share on other sites More sharing options...

Tim Hooper Posted March 15, 2014 Author Share Posted March 15, 2014 Thanks Martin! More work on the fuselage. Filling, sanding, two coats of sanding sealer, and then on with a layer of tissue'n'dope on the front part. This is to form a smooth base for the Aluclad that follows. It don't half stink in there though........... Quote Link to comment Share on other sites More sharing options...

Tim Hooper Posted March 17, 2014 Author Share Posted March 17, 2014 There's never a wrong time to eat curry! Gentle progress on the top decking, using Flair Aluclad to emulate the aluminium of the original. Now then, if I were a real aeromodeller, then I'd be using lithoplate. But I'm not, so I'm not.

Tim Hooper Posted March 21, 2014 Author Share Posted March 21, 2014 With the curry dish all washed up and put back in the cupboard, I've pressed on with the rest of the Aluclad, and then started on the Solaretex. Quote Link to comment Share on other sites More sharing options...
