The model manufacture type most of you suggest have been already tried, .....and failed! The American company Skyshark Hobbies tried the idea of stocking wood and parts for their line of models and then produce them as they were ordered or in short runs for keeping small stocks. Most of their models were actually not their own design but an adaptation from an old USA company, updating profiles, accessories, building process and, of course, adapting manufacture to laser cut. Cost, from my point of view, was quite expensive for the time (8-10 years ago and the average price was around $300 each kit), although certainly they included high quality fiberglass cowls and aluminium spinners. At the end they even tried new own designs like a large size Hawker Tempest and a twin Me 109Z but, sadly, they didn't survive and gave up kits production going into a normal model shop, which incidentally didn't last long too. From my point of view this type of production may be took as a spare time or for just covering own hobby costs, but do not see it profitable for a living, at least in advanced west countries. Furthermore I am afraid it will not take too long till we will make the same kits price complaints but regarding every other item we use in our hobby! Many Chinese companies, always trying to fight for low prices, when the R/C hobby shrunk simply were unable to keep their prices and when tried to update them to the new conditions discovered that buyers were not willing to accept them and had to give up production.

Richard I still own a very used -and repaired- OS 40FSR and with it I keep some spare parts from a friend one which was destroyed in a crash. If I remember correctly, from the destroyed engine I keep the entire "lower" parts (crankcase, crankshaft, propeller drive, collet, nut and washer). When I get back at home this evening I might for sure confirm availability.

I remember an 80´s RCM&E issue which described how to produce an own made wire bending tool with a pair of hard wood sheet and a steel hinge. I did one myself then and it worked a treat! Unfortunately I have been unable to find the magazine issue and also bought a similar jig recently for bending a 5mm piano wire landing gear. I have fixed it with screws to my working table.

Great info Martin. Unfortunately text does not give details on the persons.

It is at least strange that being nearly a myth in UK, only one Jim Davis´ Lancaster photo has been added to this thread after 8 years and 4 pages! I would much like to contribute with a photo from Martin Hedges 1979 book "Model Aircraft", which description reads: "Jim Davis´s Lancaster model, an all-wood construction with two free-wheeling propellers and powered by two Rowena chain saw engines" Hope this makes some light to the model history.

In search of a LARGE canopy
Jesus Cardin replied to stu knowles's topic in Building from Traditional Kits and Plans
A pity you finally didn´t get the clear canopy from the German firm. And, of course, congrats on the finished BD8. This together with BD10 are my preferred planes from the Jim Bede pencil. -
Nils, if you are an experienced modeller of course they are worth building! And they even may be considered for electric power conversion. Anyway I say if you are an experienced modeller as Marutaka kits have a lot of work and they tend to be quite heavy, so an experienced eye may decide what to modify or build lighter for a better performance. In the contrary, if you are not interested in and rather prefer selling them, in this forum you may find great experts which may help with pricing but I think, perhaps, you might find more specialised support from the USA forum RC Universe, as there you will find 2 specialised thread devoted just to Marutaka brand, known there and other countries as Royal. https://www.rcuniverse.com/forum/rc-scale-aircraft-169/9401552-royal-marutaka-mk-kits-complete-listing.html https://www.rcuniverse.com/forum/rc-scale-aircraft-169/6667128-royal-kits.html Best luck with those beautiful models!

10CG is no longer supported by Futaba. Some Service Centers may still stock some spare parts and offer repair but Japan directions are the equipment is out of date and shouldn't be supported or repaired now. Anyway that problem described by Geoff is very strange as if receivers become unbound or, at least, bind led is red instead of green this should indicate in genuine Futaba receivers the transmitter is no longer sending signal and thus should be impossible to bind again transmitter with any receiver. I do not know details about compatible but not original receivers and if they may lose bind with transmitter.

NiMh Rx pack check report! ( And a warning?)
Jesus Cardin replied to Keith Miles 2's topic in Batteries and Chargers
My personal experience matches closely to that of "Nigel R". I have several 4 and 5 cells normal white Eneloop packs, some more than 5 years old and I always consistently get 1900-2050mah capacity in each charge. When I got my first Eneloop packs I went a special route for charging and maintenance and it is I fully discharge at 0.5C (1A) to 1,0V per cell and then charge the packs at 0.25C (0.5A) and at the end of every process I always get near nominal capacity values, knowing all cells are OK and the pack fit for flight. I have personally checked the AA withe normal Eneloop cells against similar AA gold Sony cells and I must confess Eneloop wins by far. After a few cycles to confirm nominal capacity for both brands packs, discharging at 1A makes an impressive difference: while Eneloop pack maintains just around 5.0V for more than an hour, Sony one fell to 4.8V -and even a bit lover- just in 12-15 minutes! -
Posted by Martin Harris on 05/08/2020 16:16:57: it's unreasonable to hamstring a global supplier by having to make completely different equipment for each market. That is just what top brands like Futaba, Spektrum, Multiplex and Graupner do and, sure, one more reason for their upper prices. What makes Chinese manufacturers shouldn't also do it? that they produce cheaper radios as an advantage for us? That´s total unfair competence in the global market.....

Along the years I have used all popular battery connectors: started with normal Tamiya plugs, then upgraded to gold Tamiya ones, later I switched to 4mm bullet connectors -both open and shrouded- to finally start using Deans when I got my first Li-Pos, but I also have experience with XT60 as I also operate model planes from my uncle and as his models are very large he adopted the XT60 as standard. I have never have any problem with any of them and never suffered heat or distortion due to bad contact and this even reaching currents of just over 60 Amps iin the ole good times with Ni-Cd batteries and gold Tamiya connectors!. Anyway I opted to stay with Deans due to small size and being appropriate enough for the actual currents on my models. Also, against what I have read a lot of times in this forum, soldering Deans connectors has not proved any problem for me, even using just a 15W solder and not being, really, a soldering genius. For adaptors, many years ago I made them using a short cable between connectors but learned from expert that that produced loses so my only adapter todays is made soldering direct a female XT60 connector to a male T-Deans one and I use it with my last charger (ISDT Q6 Pro) when charging Deans Li-Po and when using those for flying my uncle large models....with total success for now!

I can only speak for me, but regarding your questions: - Do folk have many adaptors?...I just own one, this is for using XT60 connector batteries with T-Deans ESCs (T-Deans is my standard). -is it a soldering job quite often?...Well I intend buying only batteries with T-Deans connectors but, of course, i keep some females T-Deans connectors for if I get a battery with a different connector. I find soldering T-Deans connectors not too difficult. -Do the same batteries come with different connectors?....Not those I normally use. My preferred brand have been always offered with T-Deans. Anyway I know other brands that switched battery connector when they upgraded batteries C´s; I think they though that their new, more powerful, batteries would be used on more demanding models and they changed from T-Deans to XT60.

Well, it does not only happens with overseas alien firms! I suffered similar from an old good UK bookshop selling through Amazon just last week. I wanted to get 5 books of ASP vintage collection "Radio Control Handbooks" and as I wanted to keep within a limited cost, decided to order 2 tittles from one GB second hand bookshop and 3 other tittles from a second one. Order for the 2 first titles went great: very good prices (I have to wait to check books condition when they arrive to Spain!) and a competitive combined portage cost but, I am afraid, things went not so pretty with the other 3 books. After finishing the order and checking-in it, I found that shipping cost simply tripled for a single book and was near twice the books cost so I contacted the shop so as they revised their shipping combination configuration, only to be explained that they wrote cheap prices for their books (2 were really cheap, the third one not) as they compensated them with shipping prices, as many sellers do in Ebay since many years ago. I was simply shocked as I could not imagine this kind of selling practices from a Bookshop and even less so with one selling through Amazon. I though of buying these 3 books from other sellers but as one was only available from them and sourcing the others from other bookshops also produced high posting charges, finally decided buying the 3 books from them but that does not change my mind and surprise of finding a professional business trading in such way! From more of 35 years buying from UK magazines, model shops, bookshops and particulars I had never before found such situation..... Edited By Jesus Cardin on 28/07/2020 12:49:19

Do you think it is just a coincidence that HobbyKing suffers from low stock and bad service to customers just since it all started in 2018? Probably it will be the end of HobbyKing as "Test Pilot" suggests but in no way it will be the start of a new era to old models shops and distributors. I am sure that just in a few days a new firm -HobbyQueen, perhaps?- will surface with, oh!, those same products and prices offered now but just rebranded.....

Effect of thicker wing tips.
Jesus Cardin replied to David Hall 9's topic in All Things Model Flying
Thicker wing tips hs has the same effect than wash-out: it makes the wing tips to stall after the centre wing section. Anyway if you are going to go with a tapered wing, you should do some drawings so a to keep with a difference of 2-5% between central wing section and tip one. Above those figures you may even find problems to turn as there is the risk of an adverse yaw effect due to wing tips large drag. -
I also like aviation art and own both comics plus 2 paints. Hugault probably is the best aviation comic artist today but I discovered this type of histories when a teen and from my preference for Sci-Fi comics. Then discovered and got hooked on "Ace of Spades" from late Argentinian artist Juan Gimenez, who produced mainly Sci-Fi Tech comics. If you do not know this title, I greatly recommend you lool and buy it. You will not regret! Regarding paints, first one was produced in the early 70´s by demand from Spanish model airplane firm Modelhob and was on the direction office wall till 1994, when the firm closed. It depicts a HA-200 Saeta formation training flight. It is now in the wall of my main bedroom. Second one was painted by a workmate and very good friend in 2001 for me and depicts my favorite plane, the Messerchmitt Bf 109 (on the paint, the late G-10 version). Since he presented it to me is the main pain at my home living room. Wish you like them! Edited By Jesus Cardin on 19/07/2020 21:01:35

In search of a LARGE canopy
Jesus Cardin replied to stu knowles's topic in Building from Traditional Kits and Plans
If you do not find the canopy in UK, perhaps this German company may supply one from their 1/3 scale Bede BD8: http://www.modellbaumuder.de/bedebd8e.htm Edited By Jesus Cardin on 30/06/2020 12:57:57 -
"Murat" I think you have mixed comments! It was me who wrote about an issue of RCM&E and a review, but it was for HMM Focke Wulf ta-152H, not the Moonraker. Then "Cuban8" explained ha has a video with Mr Metcalfe talking about his models at a R/C hobby show. If you are interested in the HMM Moonraker review you have to look for RCM&E May 1989 issue. Unfortunately I am of no help here as I do not own that issue, but sure you may found it at Ebay.co.uk or at Magazine Exchange.

Maurice, first points to check: - Reversed throttle? - ATV/End Points to 100%? - Motor trim at middle or at lowest position?

Posted by Cuban8 on 23/06/2020 13:11:54: I have an extensive collection of modelling and full size aviation videos, all now on DVD, going back almost 40 years and I'm sure I've got a video of one of the Sandown Shows around the early 90s that has Howard Metcalf talking about his models including 'Moonraker'. I'll dig it out and try to put it on YouTube when I get a moment. Edited By Cuban8 on 23/06/2020 13:12:58 "Cuban8" sure many will greatly appreciatte that! I bought my HMM Ta-152H after reading the RCM&E review. A magazine I still keep!

"Gsky" if it is your first balsa built, please, be careful with the building instructions related to glueing formers to fuselage sides. If I remember correctly photos show all formers glued to one fuselage side and then glueing second side and going for the rear fuselage taper. That´s totally wrong! You will have to glue only same width fuselage formers (from bulkhead to just rear of the wing) first and then glue together fuselage side ends and go inserting rear bulkheads while keeping fuselage taper symmetrical. If you go as described in the manual you will end with a beautiful banana shape fuselage! Aside from this I do not know of any other important error and if you build it carefully you will be regarded with a very fine flying model. Best luck with the building.
