Club ED
ED engines have been under represented in discussions on this forum.
In the 50's and 60's, ED was one of the "big three" (ED, DC/Frog and Mills) in the UK.
Please feel free to comment on ED engines in this thread. Whether it is an ED Baby, Bee, Hornet, Fury, Penny-slot, Competition Special, Racer, Hunter or Miles, or one of the later "Super" range; this is the place.
To kick off, a 1957 ED Mk III Racer 246, magnesium case. It's noisy, it's oily, and it's well used; but it has character aplenty.

RE: Club ED
G'day
Back in the early 70s, a bloke turned up at KMFC at St Ives Showground in Sydney with a control line trainer and an ED 2.46 Super Racer in it. I got the job of showing him how to run it in and later I taught his older son to fly with it.
I remember it as being quite powerful and very easy to start and tune.
But ... I mostly remember it as the engine that tried to eat his younger son. The kid was about 5 years old and was running about all over the place with dad not taking much interest. I was teaching his other older son when the young one suddenly decided to run into the circle to be with his brother who was flying the plane close to the ground. The plane hit the kid on the arm and left several nice cuts there. They were not deep and he did not need stitches but he was lucky it hit his arm and not his head. He was also lucky it had a nylon Torpedo prop as they were not all that sharp. A modern APC would have really made a mess.
As a result, the ED Racer is one engine I am not likely to ever forget. I never did see any other ED engines though.

RE: Club ED
Well done Fiery ,
a Classic motor
,and well secured with Nylock nuts , I secure my Silver Swallows with 2.5mm Nylock nuts
That would go just great in a Toreador , and the 8x6 would sound good with a bit of missfire like Diesels do
I have a case for a 1.5 , might take a few years to find the rest

RE: Club ED
I flew a second model ED Racer on a Ron Prentice Big Fry in control line Old Time Stunt. The only several hundred flight airplane which I never crashed. Also, I built the tank in and got it right. I found an 8 x 6 to be the best prop. I few the airplane some with a Super Racer and did not think it did as well as my original Racer

ED Racers.............certainly Sir.............
...curses-pics won't upload for some reason-aah that's better. A selection of mine-not a complete set of course (in both senses of the word-not all of my Racers-and not all the different models that were produced-I'm still after a 'Super Racer' (known as a Mk6 by some)

Fiery-I've just taken these pics in the last 20 mins-and its possible I didn't shrink ALL of them before trying to upload (I certainly shrunk most of them)-there were 7 in total I was trying to upload. As taken they were ~1.5MB each-and the site has a 6MB upload limit-so if I missed shrinking one, it could have taken me over the limit-and I got a 'file size too big' message on the second attempt at uploading all 7, so I did it in stages-and encountered no problems.

RE: Club ED
Aah-yours is a March 1957 model from the serial number, mine is September 58. Racer serial numbers always start with 'R'-the second letter is the month of manufacture (A=Jan, B=Feb....M/N=Dec, 'I' is not used to prevent confusion with '1') and the last letter is the year of manufacture. This works from the late 40's into the early 60s-till about 1963 when ED went bust-the later 1968-thru 1970s EDs seem to use a different serial numbering system. Surprisingly the first one works extremely well-with very little ambiguity-about the only model where this could occur is the 2cc Comp special-which was in production from about 1948 through till the early sixties-thus a serial number ending in '9', or '0' could mean 1949 or 1959, 1950 or 1960, (ED adverts were still listing the Comp special as late as Sept 1960)-but there were usually sufficient minor detail differences to enable the production decade to be determined.

Aah yes-the gospel according to Gordon Cornell-no one else know anything about designing, building and marketing engines, running a company, the realities of a depressed UK economy etc etc.....................
let me see now-how many Dyedesyne Dynamics,Tutors, Dynamic 061s, and Dominator 3.5's did HE produce and sell...........?

RE: Club ED
As you can guess I quite like the odd ED.
I have most of the common ones, but I'm still looking for a Cadet, Pep, Reed Valve Racer and of course dream of Miles.
I've flown all the Hunters, also the Comp Specials (another ina plane up in the shed) and Penny Slot.
Just building a slightly enlarged Malmstrom Mimi for a second Baby - it has very light RC on rudder-elevator so may be a little interesting!
My plan is to fly them all eventually, but maybe that's a bit optomistic.
In the meatime it's great fun to run them all from time to time (I have a VERY oily corner of the shed).
Images won't upload , so maybe another day.

RE: Club ED
I have a Bee Mk1 in a Macchi free flight model that runs well upright, but is a worry head down... Ask me how I know.
Comp. Special in a Frankenstein, that goes REALLY well.
Nah, sorry guys, I can't get pics on either.........But yáll know what Bee's and Comp. Specials look like.

I have two Hunter 3.46cc engines # 4M61 | 51 and # 4D 955.
The earlier engine is taller and I and I assume the later model has a higher bore to stroke ratio. I was wondering if this design change been described by anyone writing about the history of 'Electronic Developments' and if it altered the performance noticably?

RE: Club ED
I have three Hunters, I'm pretty sure they are all the same bore and stroke, but the first model is taller due to a longer conrod and cylinder.
SeriesI has a finned head and tall cam turned cylinder (has a bulged section for the transfer, long prop driver.
Series II has a silid head, short cylindrical cylinder, long prop driver.
Series III has a green solid head, short clinder and short green propdriver, green spinner (green parts were shared with teh Taplin Twin).
All run really well, but I can't pick much performcne difference, certainly on the fairly large props I run.
One has an ED throttle, I've found it works best on the greenhead which has the least sub-piston induction.

ORIGINAL: fiery
To kick off, a 1957 ED Mk III Racer 246, magnesium case. It's noisy, it's oily, and it's well used; but it has character aplenty.

An old modelling friend of mine has been slowly getting rid of his extensive collection of engines on the bay, and decided that I needed a couple of diesels so sent me home with a suitably lightened wallet and a couple of engines that 'every modeller should have'. A Mills .75 and two Racers.
One of the Racers (RA1094 would that be Jan 1954?) has done very little running and is in pretty good condition. It also has a loose piston pin and one of the bridges between the exhaust and transfer ports broken out of the liner. I presume one led to the other.
The other one (RD86 Apr 56?) has been well used with faded anodising, bodged up tommy bar, prop driver, and spinner, missing the prop washer, and with the exhaust completely filed off. I guess it's done some time in a team racer. The piston has a reasonable score in it and the compression isn't great but the engine runs OK I think. Well starts OK most of the time (other times it's quite bitey, I'm just a beginner at this diesel stuff) and turns a 9X6 Master at about 8800.
So transfer the old piston and liner into the good engine and I hopefully have a reasonable engine for a vintage radio assist model. I'm thinking either a KK Junior 60 or KK Super Scorpion. I'll only fly the Racer on the odd special occasion though (that noise thing aqain), the rest of the time the model will fly with a DDD OS 20 FP. I suppose I could use the newish piston (with the loose pin) in the old (but not broken) liner, but I have no idea if it's possible to tighten up the gudgeon pin or if you can swap pistons and liners.
Thanks for the video Fiery, what size prop and RPM are you getting?
Also what fuel do you use?
I'm using 20% Klotz castor, 30% ether, and 1% ignition improver. I'm thinking 10X5 or 10X4 prop might work on the vintage model (one of the club crusty old bug aaah, veteran modellers seems to think they might have used 8X8's team racing)
Oh you're right about the character too.

RE: Club ED
Fiery,
Some more questions;
Where did you get that needle?
I noticed on your other Youtube videos that you also have a 40 FP with what looks like a MECOA head. I have a 40 FSR that I am keen to dieselise. The MECOA site reckons that head will fit on a 40 FSR but Davis reckons his 40 FP head doesn't. I'm not sure whether to just buy the Davis head and hope or buy the MECOA head. How do you like your MECOA head?
Thanks Fiery, great thread

RE: Club ED
A longer conrod reduces the side forces of the piston against the cylinder wall.
I suspect they went for a shorter rod as they found that wear was nnot a problem and could geta more compact engine which was no doubt justa little cheaper to produce as well.
The move to a plain head was probabaly to save cost also as they found the fins were not really necessary.
Photo's finally loaded this time, see my earlier post.

RE: Club ED
Winston-yours is definitely the early model-but the ED Hunter first appeared in 1949-so yours is more than two years into the production-Dec 1951 from the serial number. Not a highly thought of engine in its heyday-mainly used in C/L and for lugging around large slow RC models in the early 50's-ironically it took the Americans to discover it was a 'sleeping giant' for Class A vintage events in recent times-now its the bees knees-even to the extent of CS making a .19 size version for the US market.

I thought this was thread for people suffering from ED. I was amazed that you were all so OK with it that you were ready to talk about it publicly.
I guess I misunderstood.
