What questions doesn't it answer Don? I'll try harder! Ian.

Posted by Don Fry on 28/10/2018 20:03:20: So Reg, how do yo propose to install your bit of wire in the finished model.. either the wing tip, or the flap is in the way. And I am stilll waiting an explanation as to why the plan drawn geometry is not good. And the leeway in the hinge hypothesis does not hold much faith. Why does it strain the hinge. I might be talking out of my backside, but a reasoned explanation would educate. You'd build a tube in the tip and the end of the wire would have a small return on it that would be recessed into the tip outline. This could be found when the aileron needed to be removed. Robart pin hinges have a small hingepin so the naturally want to bend in that direction. Any bend not in that said direction will bend the plastic and not on the hingepin axis. Try it, rig up a simple surface with just two hinges and you'll feel a strain when the hinges are in any other orientation other than lined up. Ian.

Is that the 96" span Mannock? The weight for that would be nowhere near the weights I quoted for the 1/3 SE5a models. I would imagine the 33GT would more than power it on it's own. Ian.

Cymaz, have a butchers at the Martinsyde Elephant for inspiration. Ian.

That aileron hinge is simply a joke in engineering terms, as is the Topflite 'professionally designed geometry"! As stated, the hinge pins must be in line or the hinge is relying as much on the flexibility of the plastic as it is on the hinge pin. I would vote for using Kavan flat hinges but replace the little hinge pin with a length of piano wire that goes through all hinges. The beauty of this is that you can do all of the hinging and linkages etc, then remove the aileron by pulling the pin out so covering, painting and maintenance is easy, you'll also be able to put the aileron on and use it without straining any of the hinges. Ian.

Hi Cymaz, what is the SE5a, , which plan, kit etc. There are a couple of SE5 designs out there at this size and they vary massively in terms of accuracy, structure and therefore final weight. The lighter ones come in at about 17kg, the heavier ones at 25kg plus. The worst design (just my personal opinion obviously) is the newish offering from Vailly which is available from the States or Belair in the UK. This ends up being heavy and has a massive thick wing and looks and is very chunky in its design. The best design (again, just my humble....) is the old Dennis Bryant plan, available at 1/4 but blowuppable to 1/3 with no alterations whatsoever. Quite a fine design, no missing info and very accurate. These end up around the 19 / 20kg mark. The lightest are a blow up of the DB Sport and Scale 1/4 scaler. With these differences in weights and sections etc, some need greatly differing power to fly properly. Up to 20 kg and the geared Zenoah 38 Toni Clarke unit flies them well, using a 32" x 18" prop. The heavier ones obviously wouldn't fare as well on the same power set up, but presuming the 33GT kicks out a good chunk more grunt than a Zenoah 38 then a similar gearing with a tad more pitch would do well. You could be really posy and go for a four blade 32 x 18 if your mate is building the geared Wolesley SE5 version. Ian.

Blimey, just remembered and found this!! No updates as yet but I hope to restart it next. Been a busy couple of years with house moves, workshop builds, narrowboat restoration etc and other stuff going on so toy aeroplanes have been sadly neglected. I think I have all the materials to get it done so fingers crossed!! Ian.

Building, when does it become too expensive to fly

Posted by David Davis on 24/10/2018 11:58:28: Posted by Jon - Laser Engines on 24/10/2018 09:12:51: ... David, you wont need anything excessive on a model like that as its not exactly a rocketship. I would say that anything 6-9kg standard size would be plenty. Which servos from the Hitec range would you recommend Jon? Hi David, I've built a Reeves Camel at 1/3 and used Hitec 645 mg servos on all the flying surfaces. One on each elevator, one on the rudder and one for each pair of ailerons, left and right. The ailerons were controlled as per the Reeves plan, belcranks under the lower wing to servos in the fuselage. Elevator and rudder were close loop with the servos in the same place as the aileron ones, under the pilots seat. That might seem overkill on servos specs, but going over means the whole electrical system gets an easy ride and ends up very reliable. That said, the ailerons are large and a pair to each servo. The static loads can mount up, plus also factor in the loads of taxiing over roughish ground and the weight of the surfaces jiggling up and down. Hope this helps, Ian. -
As others have already said, what a grand day out! Many thanks for the great turn out and a massive variety of models which mostly coped well with the strong winds which prevailed most of the day. The depron airliner of Simons was amazing in the conditions, flew rock solid at proper scale airspeed. A tremendous days playing and Dave P's video of my Pup has made it more memorable, I think he did a great job considering the conditions and that it was also the first time we'd tried. I had the easier job, just to fly a boring biplane as smoothly as the conditions would allow. It was agreed that I would take no evasive action whatsoever, relying on Dave's quad flying skills to avoid the ole stringbag! Thanks again for a great day, Ian.

Forecast isn't bad for Sunday, gate code is 109 for visitors and due to the two lock set up, club members can use the normal lock. Please ensure to lock up as you find it. That said, the gate will be manned till about 10.30. Absolutely any scaleish model welcome. A Pup, Flea, HP42 and a foamy Spitfire for me. What's everyone else bringing? Ian.

The full size Archeopteryx is being restored to fly by the Granger family. It is due to be test flown by Rob Millinship at Old Warden where is destined to be based. We went over to have a look at progress a good few months ago and the blokes workshop was fantastic, free flighters hanging on anything hangonable and a Stanley Steam Car in the corner, fully useable and a regular driver. Who's was the model Geoff? Please tell me he and it is coming to the scale day? Ian.

Hi folks, as promised we've scoured the available weather sites trying to find one we like but to no avail, so the decision has been made to postpone until the Sunday after, which is the 21st. Thanks for your understanding!! No doubt it's going to be lovely on Sunday now and nice all week, turning nasty again for a couple of days on the 20th!! Ian.

If you want to stay with the basic design, you could get some tube that slides neatly over the wires, then sew the tube to the formers and build as normal. The U/C wires would be separate sides which slide into the tubes after covering and painting. Or, altering the design a bit, fit ply plates across the fuselage and screw the U/C externally to that. If the fuselage is very narrow, the half width might not be strong enough to hold the U/C well enough, but you could double up the tubes and then each wire could be full width. Just a thunk. Ian.

Hi technical peeps, is there a way of printing a whole build thread as a document? I'm sure I saw one printed out that just contained the thread and none of the adverting and banners. Is it possible? I want a paper copy of my Bertie Bassett Flying Flea build as it contains some details and pictures that I don't have any more. Many thanks, Ian.

I reckon it is a repaired Premier Tiger. The fuselage has the same 'hump' to it in that the cabane stuttery is mounted far too high. The top longeron on the Tiger is straight with the struts mounted to it. The Premier Moths struts are mounted well above the longeron and gives a hump back appearance to the side view. Nice project for a refurb!! Ian.

Some great subjects in there Roo! Ian.

Never noticed this topic, let alone its clone!! Here's a few pics of my den, wriggly tin, railway workshop style.

Hi onetenor, somewhere in there is a silver Spitfire in Dutch markings, but the wings stood on end in American markings are from the P47 Thunderbolt on the bench. Silver bundles on the left, which picture? I'm well chuffed how the 'in the roof' storage can be utilised, the trusses are superb at absorbing airframes!! Long term storage at the top as they are hardest to get at, though in reality anything can be got at quite easily. Airframes in here at the moment are 1/2 scale Flea and Stits Skybaby - 2/5 scale Sukhoi Su26 - 1/3 scale Pup, Albatros C.III, J3 Cub, Fournier RF4, Tipsy Nipper - 1/4 scale Wellington, Yak3, P47 Thunderbolt, 2 x BP Defiants, Zero, Zlin 326 Trener, Republic Seabee, Albatros DVa - 1/5 scale Hurricane - 1/7 scale Junkers 52 - 1/8 scale Handley Page HP42, plus a few rubber and indoor scale stuff hanging about. Ian.

One of the most inspiration scale modellers ever. Memories of his models and the published plans will live on forever. Many thanks David. RIP to a truly great man and modeller. Ian.

Here's a few pics to show that no matter what shed you have, it always gets filled to capacity and then some! After ages of not being used for its designed purpose, it now is back to being a toy aeroplane shed, a hopefully busy one at that! Gone (for now at least) are the various narrowboat restoration and window frame making bits of gubbins that has taken up precious space and time for the last few months and for the first time in what must be four years I have a useable shed and more importantly the enthusiasm to use it! On a sadder note though, we lost one of my modelling heros recently, RIP David Vaughan, a truly great bloke and modeller. The memories of his modelas and plans will live with me forever, many thanks David. An inspirational man and modeller. Ian.
