Thread: Twin Otter - Electric Twin from Anton Eisele Plan
07/12/2017 23:02:07

My final posting today just shows the splitting of the ailerons from one of the wings. This is not a job I have been looking forward to as it is difficult to measure where the cuts go. The new trailing edge can be see (oversized before planing and sanding).

I have had some graphics arrive from Callie in the USA. I will be dressing the plane as a WinAir Twin Otter, mostly white, with stripes, blue tail and wing centre panels and red rudder. I decided against the yellow Canadian military strip as it has been done before. Similarly, I avoided the US para team. The former was available as a VMAR ARTF, the latter a Hangar 9 ARTF. For those impatient to haqve a new Twin Otter, I saw on Ebay that a German ARTF manufacturer is doing a Swiss survey liveried version (very nice it is too). It's rather expensive and with the power trains it will cost about £400 to get into the air plus battery and radio. Mine will cost about half that even after buying Oracover.

This time there is a photo of the tail mocked up. Others who have made this plane have said that although the tail seems to work OK it is rather prone to damage when the plane is handled. The main problem is weakness of the fin. I have doubled up some of the frame and used 1/64 veneer each side of it under where the stabiliser or tailplane is fitted. It is much stronger as a result. I am going to use two Savox 225mgs to operate the rudder and elevator, deleting the two heavy standard servos in the middle of the plane under the trailing edge of the wing.20171203_201451_resized.jpg

This is the stage where progress seems to slow. Work becomes more to do with details that creating structures.

I am trying to keep to the original plan as far as possible because it was the basis for a commercial kit many years ago so it was basically well sorted and also modifications usually mean more weight. However the photo below shows a depature from the plan which had a standard servo in the middle of the plane operating the front wheel and the rudder via long control rods.

I have used a sprung noseleg, I believe it is a Dubro part but i've had it so long I could be wrong. Also a small metal geared servo is used for steering with control wire bent in a elongated 's' shape (not visible in pictures). This should have some shock absorbing properties as a result. The servo is just under the cockpit of the plane.20171114_121603_resized.jpg20171129_214902_resized.jpg

Thread: BMFA Online Membership portal open for 2018 membership renewals
02/12/2017 10:17:17

I am responsible for the membership in our Club as well. The new system of on line renewals is a huge improvement together with the facility for on line payments. There is one further improvement that could take us up a further level. It would be useful to be able to print off a list of members from the the website to be able to check our work without having to wait for the list that comes with the certificates.

I did email the BMFA about this but didn't get a reply. (which I am afraid is quite typical).

Dreaming on........Having electronic certificates for one's smart phone would take us into the 2010's and save alot of messing about as well as postage. Maybe by 2025?!

I was in Als this morning and all they had were G Force modules (can't think why I would want one of those?) nothing else. Good news that we can get Spektrum stuff serviced but will level of service match HH UK centre before it closed I wonder? The 50% increase in prices is still an issue. Yes I know the exchange rate has moved against sterling but the dollar prices in the States seem to indicate a little mickey taking.

21/11/2017 19:20:25

One of the best features of the DX9 and other Spektrum transmitters is the 'talking' telemetry. After having a problem with Lemon telemetry, I thought I would use the original TM1000 module that came with my transmitter. I was interested in an altimeter. I find that when they were sold by a wide range of retailers they used to cost around £50. There are very few for sale now (Als Hobbies don't have any stock for instance) and even those retailers willing to sell them on the web want £76 for them, an increase of 50% (approximately in case BEB is watching!).

If I was willingly to run the gauntlet of buying on Ebay from a seller in the USA the price is $49 (about £35) plus postage, VAT, Royal Mail tax etc,

This price increase I believe is fairly typical of Spektrum products and with the closure of their UK service centre factored in it would seem they are sending a very clear message to UK Spektrum users. Sort of 'Goodbye!'

Thread: AXI Motor repair
03/11/2017 19:57:11

I have an AXI 2826/12 that has very noisy bearings and needs an overhaul. Apparently, there is a kit available from Electric Wingman. That's a good thing. The bad thing is that AXIs are reputed to be difficult to take to pieces.

Has anyone done this? How did you get on and what tools did you use?

Hopefully, someone can help, please?

It is surprising that there is very little on the web about this, there appears to be no UK repair centre and the AXI website makes no mention of service. One might think 'not good enough' considering the cost of the motors.

Thread: Twin Otter - Electric Twin from Anton Eisele Plan
20/10/2017 22:27:35

I've started on the wings now. I have decided to build the wings entirely as normal and then cut the ailerons out. Similarly the engine 'gap' will be cut out later. The ribs have holes in them for the wiring. I never seem to be able to make a good trailing edge by camfering the top sheet and sticking it down along the edge to the bottom sheet. Instead i have planed the edge of the wing and glued on a 3/16 by 3/16 strip. This is then planed and sanded to an edge about 3/32 thick.This is a similar idea to when trailing edges are put on foam cored wings.

There are two relatively inexpensive tools I use all the time. One is a plastic ruler with notches to gauge balsa sheet thicknesses. The second is a Great Planes sanding bar about 2ft long. Both seen in the picture below.

The fuselage has had some stringers added and part of the nose. So far it is entirely as per plan. I'm not quite happy with nose in the original design, it looks too 'beaky'. This is probably because the designer wanted to make construction simple avoiding compond curves. I'm not about to make it more complicated. I just think by shortening it a couple of cms it will look better even though it will be less to scale.

Sooner or later I am going to have start on the wings. There are in set ailerons and I am showing the catch-all cross section here. The wing is easy enough, looks like Clark Y but I have some fear about building the ailerons. I really prefer to build them as part of the wing and cut the out but it doesn't look like that is possible here. The idea of getting an accurate chamfer on the 1/4 sheet aileron leading edge of the aileron looks very challenging as well as building using fiddly little triangles. I going to have to think of a another way.

I will be using separate aileron servos and no bellcranks.Servos are one of the few things that are cheaper than in 2004!twotter wing sect.jpg

09/10/2017 21:29:45

The front and rear components of the fuselage are now joined. Tomorrow I'll start on the stringers.

Pictures from my phone often post here upside down.

20171008_211403.jpg20171007_174137.jpgHere's some pictures of the early stages of the build.

The fuselage is in two main sections. The main section at the front has parallel sides. I cut a sheet of 1/4 balsa accross the grain the exact width between the frames and then slice it for the sticks in between the sides. I set it up using 4 set squares.

The rear section is just a straight taper built out of two frames and again 1/4 square sticks in between. I ruled a line on a fresh sheet of plasterboard and marked the centre of the front cross beam and pinned the tail triangle down to line. It seems to work. Underneath both sections there will be notched formers to take stringers.

There is an article on the web giving the designers notes on the build found here:


I will try not to duplicate this too much and only give some comments that add to that article. The plane dates back to about 2004 and since then digital photographs have vastly improved on the old grainy images. Hopefully my pictures will make it easier to visualise how the plane is built.

I am leaving the frames to dry thoroughly before fettling the joining surfaces so that when glued I get a straight fuselage.(Hopefully!) I don't use cyano because the Modellers White Glue gives more time to adjust components and sands better.

I seem to remember Peter Rake has used this system of two module fuselages in his WW1 biplanes. The result is a rather boxy fuselage but there is no stress during construction and it is comparatively easy to get it straight.

Regarding the Hangar 9 version, I think it's quite a bit bigger than this one - it weighs about 10/11lbs whereas I'm hoping for 5/6lbs for this. H9 TO has its batteries behind the engines which saves wiring length and a little weight but against this there is the possibility of battery voltage imbalance and the fixed position prevents the batteries being used to balance of the plane. Not a criticism, the designs are just different. H9 version is a lovely plane, a triumph of production, lets hope I can get somewhere near it!

Apart from a Twinstar, I have built a Eurotwin and a Short Scion. In all of these having a single battery worked out fine. I didn't experience any motor problems having fairly long power supply wires to the ESCs mounted behind the motors. Perhaps with bigger motors it can be a problem.

I looked at the Ivan's TO as well. It was too big for me and looked rather fragile. Unless laser cut parts are available it looked a challenging build and I would be too frightened to fly it having spent that amount of time and effort.

Parachutists eh! Sounds great. I think I will use mine for carrying a camera.

I am currently building from this plan that I bought from in the USA. The plan arrived quite quickly, about 10 days and post cost was $14. There was no Duty or VAT. The plan is on 2 large sheets and is nicely printed and I rate it at good value at $19.95.

It wasn't easy to find a suitable plan. The ones I found on the web are too big or too lightly constructed for my purposes. This one is semi scale which doesn't bother me as I want the plane for everyday flying. At 65 inch span it is about the same size as a traditional trainer.There is a huge range of liveries available to disguise its appearance!

Hangar 9 did an artf slightly bigger than this a few years ago and currently there is another quite costly artf availble from Europe. I believe they are all good fliers - the Twin Otter makes a good prototype to turn into a flying model. The good ole Twinstar is a great flying plane and I believe the Hobbyking twins go well too. But it is nice to have a balsa model that's been build the trad way.

There is a youtube video of the plane I am building at **LINK**

I have spent some time time studying the plan and there are only a couple of minor errors found so far. The AirAge web site has links to some building instructions. Originally the plan was for geared 480 brushed motors and Nicads. Standard sized servos were used with long rods to the tail and bell cranks to the ailerons.

I am not going to change the plane extensively apart from up dating the servos and motors/batteries.The large fin looks rather fragile so a few strips of carbon will be used. I think adding flaps will only increase weight and complication without any real benefit. The plane evidently takes off in a few metres and has plenty of drag to slow it down.

I hope this will be of interest. Given the advantages of electric for twins it is rather surprising that they are still quite a rarity. Some photos of the build will follow in later posts.

Thread: model shop service

Agreed BEB. I'm going to get down to posting a few pics of a Twin Otter I'm building from a plan.

06/10/2017 22:43:22

Seems strange that the recondite 'Arcana' poses no difficulty for Flight 1 but webbies and webbs are a problem! There are so few good model shops left most of the forum members know them (and their diminutives) off by heart surely?

Thread: Werewolf
09/09/2017 23:24:16


Many thanks for your reply. Nice to have the original designer on board.

Looking at the dimensions of my Saito it is about 2cm longer than the engine on the original plan. It looks like I will have to move the firewall back a bit to make room even if the plan is enlarged 10%. This shouldn't be a problem as long as I do some alterations on paper before I start.

The first plane I built wasn't the Midget Mustang but the Lil Mustang. I went to compare the plans and discovered I had mis-remembered.

I loved the look of the Seagull Yak 3 in the recent RCME (July). No chance of you doing a Russian Werewolf version of that is there by any chance?

Thanks, Ian.

08/09/2017 17:05:56

Reviving an old thread here. Would like to build one of these. Had a Peter Miller Midget Mustang (the original one from about 2007) and it flew very well using an Enya 30SS. Sadly the plane and the engine came to an early end when it ran out of fuel turning into finals. Werewolf looks like an interesting development of this type.I have a Saito 56 but this might be a bit much for this plane unless it is enlarged say 10%. Any thoughts from those with experience of this plane would be gratefully heard. Sorry for the slab of text for some reason the new line key doesn't seem to work.

Thread: Glider Wing Warp - Top Model CZ Bliss
17/08/2017 21:23:40

I'll let the rather excessive glue dry overnight and see if it holds the new twist in the wing. Posting here has stopped me just whingeing about the problem and encouraged me to do something about it!

Removing the bottom covering had no effect on the warp. You might expect some change if the tension of the covering was causing the problem. The wing is quite short only about 700mm so the structure wins against the covering. I am sure John's method would work on longer wings but not here. I can't heat the top of the wing because its covered in vinyl decoration. Having been encouraged to remove the covering I am going to see if adding diagonals while holding the wing in a twist will work. I'll post another picture separately as they seem to get pushed into strange places in my text,
