RE: Radio Control Scale Aircraft Quarterly - who owns the rights to this magazine now?
It is clearly a JU87D1 according to the tiny plan in the magazine -RCSQ Oct Nov 1990 so I expect it's just an error on MyHobbyStores computer ( not uncommon! )

RE: Phillip Kent 1/4 scale Aeronca C-3
I found the article for the 1/6 scale C1 in MAN June 96 ( it was also published in Radio Modeller in England some years earlier I think ) The construction might be similar on the 1/4 scale, that is F1 , F2 & F3 are built as a sub assembly with the engine bearers then attached to the partly assembled fuselage which is still attached to the building board. Use epoxy to attach sub assembly and use masking tape to hold in place. Hope this helps. If only I had seen this before Saturday I could have asked Phillip when I had a chat with him about his Comper Swift!

You can also obtain Philip Kent's plans from the man himself see http://www.brighousemac.co.uk/Scale_Plans.htm There is an e-mail address for him there if needed He was at the Old Warden scale day on Saturday flying his 54 inch Comper Swift - another really nice scale electric model in a handy size. He does a 1/3 scale 96 inch Comper Swift plan too.

RE: David Boddington 1932 - 2010
Actually David Boddington sold DB Sport & Scale back in the 1980's when he became editor of Radio Modeller. Then he was editor of RCME then Aviation Modeller Int then RCModel Flyer Scale Aircraft Quarterly, Flying Scale Models. Some of his plans are in the plan service of each of these magazines. RCME, Radio Modeller, Scale Aircraft, X List Plans etc are now MYHobbyStores.co.uk AMI, Model Flyer, Flying Scale Models, Aeromodeller are now ( this months news ) all one publisher (ADH Publishing ) so all the plans will come from them. Big news from ADH this week is that they are bringing back Aeromodeller and a new RC Electric Flight magazine later in the year. DB Sport & Scale still sell their own range of kits & plans this is a link to their page about 'Boddo' http://www.dbsportandscale.com/40_years_on.htm RCM plans have 2 of his designs - Mighty Barnstormer and Ghost Rider RCMplans.com So if you want to know where any particular plan is ask and maybe we can tell you who sells it. I reckon all of the great 'Boddo' s plans are still available somewhere in the above sources.

RE: Enlarging plans
The safe and easy way is to look at a similar size and type of model and use similar construction methods and material sizes. It's much easier to restyle an existing design of the right size and just make it look like your desired shape. Probably fly better too. But in this instance it's a huge change of size and probably not have ailerons & rudder if it's control line so better avoided. You will spend so much time and money building a large model it's better to do it properly. When you can download a free plan for a Howard Pete ( OK its low wing! ) at the right size why not build that? In any case study the construction methods and see if its applicable to a Mulligan. Look at the David P Andersen page [link]http://www.mnbigbirds.com/Andersen%20Plans.htm[/link] for this free download from a top designer.

RE: Advice on Reducing 1/8 X 1/2 Spruce to 1/8 X 3/8?
Even a razor plane would eventually do the job on such a tiny bit of spruce if you don't own a jack plane. The point about using a jack plane etc is that the downward pressure on the plane causes the spruce to seat into the bottom of the groove and makes an accurate size cut. A belt sander would be the same but dustier. Using a circular saw might tend to pull the spruce from the groove ( as the least line of resistance ) and risk inaccuracy ( causing thinness & weakness in the spar ). If you must use a saw then sandwich the spruce completely in the 'jig' ( glued in on the waste edge only ) and saw through the jig as well. I cannot understand why anyone would buy a table saw and belt sander if they didnt even have a jack or a smoothing plane! Note that the wordworkers of old ( and clued up modern craftsmen ) didn't rate planes and woodturners gouges etc as the proper tools to use for the job, rather than abrasives, just on a whim. It's because they wanted to avoid filling the workshop with dust from sanding! Dust from power tools is now recognised as a toxic hazard. We should minimise the use of power tools and only use them when essential. Saves electricity too.

RE: Advice on Reducing 1/8 X 1/2 Spruce to 1/8 X 3/8?
Thanks for the compliment David! You probably know that an Englishman's shed is his castle.... Actually the method is something that's in the traditional woodworking books, such as the ones by Robert Wearing etc. Sometimes called a sticking board. I wouldn't risk my fingers trying to cut a tiny bit of wood on a bandsaw, and it's diificult to make straight cuts with a small / cheap bandsaw anyway. Hand tools are under rated and things like wooden jack planes can often be acquired very cheaply secondhand. If you see a metal plane of a good brand (Stanley, Record, Footprint etc ) at a cheap price snap it up. They are better than the new cheap brands. In my opinion hand tools are more satisfying to use and certainly safer than power tools.

RE: Advice on Reducing 1/8 X 1/2 Spruce to 1/8 X 3/8?
Cut a 1/8 th groove 3/8 deep in a piece of scrap wood and then put the spruce in the groove and use a jack plane to plane away the excess. The jig need only be just over 18 inches long if the spruce is reversed end to end. Screw a stop on the end with a nail projecting to stop end movement and rising up out of the groove. The jig could be formed from 2 pieces of pine with an 1/8 ply insert in the middle to form the groove. Make the jig nicely and varnish it to signify it's a proper tool for future use. ( very annoying to find you need it again but used the material for something else!) By staggering the screws used to fit the ply insert you could vary the height of the ply and make the jig work for , say 1/4 and 5/16 material also. Maybe use undersize rather than 1/8 ply for the insert so the jig can be clamped onto the spruce tightly

RE: Need Advice on Cutting Consistent Wing Ribs
Clearly the tools you like most and use most are the tools you become most skilled with. So use whatever tool you prefer. However I can see no real need for a bandsaw and the real risk of serious injury to fingers whilst cutting delicate parts. A scroll saw is much safer but even that is not needed for balsa ribs. If you start with a rectangular set of blanks a razor plane quickly reduces them to shape and then a sanding block is used. And when sanding or planing the blanks are held in the vice as shown in my photo and the bolts and nuts projecting are not a problem as they would be trying to put the pack flat on saw table. Tim's emery board tip is a good one although an engineers file with a 'safe edge' is useful instead. The rib templates can easily be made with 1/32 ply which can be cut with a Stanley knife for most parts and a fretsaw used for the really tricky shapes. Spar slots are not needed until ribs have been shaped. Make the template a little over length at the TE as it's easy to make the ribs too short otherwise. Beware of making sloppy holes in the balsa as this can lead to variations in shape.

RE: Need Advice on Cutting Consistent Wing Ribs
In my opinion there is only 1 way to make ribs, and that is to cut them out roughly oversized ( with a scalpel ) and bolt them together between ply templates. The centre picture shows the roughly shaped blanks ( they could be rectangles ) bolted together. Also shows the brass tube hole punch for balsa which makes holes exactly to fit the bolts with no slop. Other pics show the Permagrit sander which is all you need not a disc sander. Also cutting the rib slots with razor saw.

RE: Cutting Stringer slots in formers.
If you really want to buy a special tool for the job buy a Permagrit slotter made in 3 sizes 1/8, 1/4 and 3/8 These have 2 'safe' edges and just abrasive on the one side. But they are not really needed unless you do lots of this work. You dont need much effort to cut a slot in balsa, just a couple of strokes with the multiple hacksaw blades if they are sharp. So a machine would not be worthwhile. On plywood just a normal scrollsaw blade cut to each side of the slot and a stroke with the hacksaw blades will remove the waste. However many plans now say just cut the top stringer slot in both end pieces and leave all the intermediate formers just plain (a bit short ) so the stringers just go on top of the former not in a slot. Modern glue is so good that the slots are mostly not needed. Here is the photo of the gadget. A piece of wood could also be bolted alongside the blades so forming a depth stop to prevent cutting too deep. ( i.e. the wood is not as deep as the blades by the amount of the slot depth ) In the background is a foam 'pincushion' which is much better than having pins loose in a tin. It wood be even better glued onto a heavy chunk of wood to stay put on the bench.

RE: Cutting Stringer slots in formers.
2, 3 or 4 hacksaw blades bolted or taped together and a bit of wood taped on for a handle make a slot cutter. Each blade usually cuts 1/32 so 2 cut 1/16 and 3 cut 3/32. Check first because the 'set' of the blades varies from new to used.

RE: Model Airplane News Astro Hog Plans
It's not that much effort to enlarge a plan by hand as all you need to draw is the basic outline. not the full construction details. If its basically straight lines then just fus side and just a few parallel lines for the wings. Measurements taken from a suitable datum line which probably exists as the thrustline etc are multiplied in a an ordinary calculator using the 'Constant' facility. Then measured onto the new paper. If enlarging from a small plan its easier to measure in millimetres and incorporate the mm to inch ( 25.4 ) conversion into the constant if you want to work in inches. If you photocopy the few curved parts ( ribs, formers & wing tips ) using a normal home printer /copier/ scanner and print at the required size you then have a copy to stick onto your wood. If you have a printer / scanner which has a removeable 'lid' you can reach into the middle of a large plan easily without mutilating it. As you will need to change the wood sizes for an enlarged version this way is just as good as an enlarged print, probably more accurate. Note that the original Astro Hog is different to the Sig version, especially in the tailplane position. One is very high while the other much lower.

RE: Making a 3-View from a photo
Deperdussin. It should be possible to obtain all the information you need as the plane is at Old Warden Shuttleworth Collection. This is a venue for model flying too and many aeromodellers visit the model fly in when they are held in May and September. If the plane is displayed at ground level and not hung from the roof it should be possible to get any detail photos you need to make an accurate scale model. The Shuttleworth magazine 'Prop Swing' in the Spring 2011 issue said the Deperdussin was having the wings recovered at that time. It is almost certain they would have made detailed drawings of the whole plane before they started. Note that the pilot of the Deperdussin in some photos is Andy Sefton who is a well known aeromodeller as well as full size pilot.

RE: Can you fly both ways?
Its more like swapping the brake and throttle pedals on your car! Or changing the steering wheel to go left when you turn it right! Try that first to save messing up your nice scale models ! The answer is to have a buddy box lead & Tx on 'your' mode and flying the other chaps model through his TX on his mode. I think its switchable in the software so each Tx is on the mode for that person. ( check first I may have misunderstood the manual!) Actually the problem with cars is on manual cars where you are coordinating your left hand ( gear change )with your left foot ( clutch ) when you are used to coordinating your right hand with left foot Therefore lefthanded Americans will probably have less problems in England or Japan than right handed Americans would. So hiring an automatic when you go abroad is much better. ( for those who have never ventured abroad I must tell you the pedals are the same on left hand drive & right hand drive!)

RE: PLAN # 1216 From RCM Plans
You are somewhat mistaken about MyHobbyStores! They are not a local hobby shop but the publisher and plans department of RCME and it's USA version RC Model Aeroplane. All the old Nexus/Argus/MAP/Magicalia/Highbury magazines including Aeromodeller, Radio Modeller & RC Scale aircraft etc have their plans here. As they publish a special version of RCME in USA called RC Model Aeroplane they have a USA telephone number 1- 877 230 2998. As the exchange rate is now about 1.59 US dollars to pound you need to multiply the pound price by that. Each model has subtle differences in many details so Street Cat is not merely an enlarged version although they look similar. The Street Cat is rounded somewhat like your version of the Sly Cat so looks nice. In some cases the wing section is quite different. There is yet another Gilkes plan called Cat's Paw which is 32 inch for a .10 to .15 and is low wing. A free plan in Radio Modeller Oct 93 (again a copy is avail secondhand with plan for 2 pounds ( about 3.20 dollars )from the source I know of )

It should still be an excellent flier though as the designer published several similar plans such as Cat25 ( Radio Modeller May 94 ) with slightly more span 44.5 inch & 8.25 chord. There is also a smaller version called Alley Cat at 35 inch span but it is mid wing ( Radio Modeller July 92 )
