Hi all,
For reasons too complicated to explain, I need information about Gipsy engines. I’m sure somebody here has the knowledge to give me the details.
What is the difference between the Gipsy Major Series 8 (like the one in the Chippie) and a Series 10. In which aircraft would I be most likely to find the Series 10?
Hope someone has the details,
Galdri.

DHFAN- The change of engine plate was purely to civilianise the engine. The Army operated machines at Middle Wallop also had electric start but they were still series 8’s.

I may be completely on the wrong track here, but all I can think of is a Gemini.
A quick “Google” brought up this:
1, 1A, 1B, 4… Two 100 hp Blackburn Cirrus Minor 2
1A Special….. Two 130 hp Lycoming O-290-3/1
2………………. Two 125 hp Continental C-125-2
3………………. Two 145 hp de Havilland Gipsy Major 1C
3A…………….. Two 145 hp de Havilland Gipsy Major 10 Mk.1
3B…………….. Two 145 hp de Havilland Gipsy Major 10 Mk.1-3
3C, 7…………. Two 145 hp de Havilland Gipsy Major 10 Mk.2
8………………. Two 155 hp Blackburn Cirrus Major 3
This seems to signify anything goes.
Isn’t the Gypsy Major in the military Chipmunk cartridge start?
I think I’ve read that they’re convertd to electric start for civilian use, hence the new designation.
On the other hand, this could be total hairy spheres.

No problem Galdri – The 10-3 now is probably quite rare as they mainly featured on some Canadian built Chipmunks .The 10-2 has a longer time between overhaul as well. I suggest if you need very specific information to contact Paul Sharman at Vintec (Little Gransden) . I think you will find he will agree with me that the way forward with her is the 10-2 because of the number of ex military examples that are around.

David,
You are really giving me some solid information here. I’ve been scraching my head going through all kinds of literature, trying to find out exactly the difference between the different engine. Apparently, all I need is a computer to find out!! Thanks again!
Hummm, so you knew about the toy!! It is a small world indeed! Hope your friend is happy with his.:D 😀

I know the toy very well ! My friend has just bought one as well!
His hangs a pair of Cirrus Minor’s tho! The Gipsy 10-1 is fairly easy to get in the U.K – I would however suggest you consider using the 10-2 instead as it’s a stronger engine from the point of view of the crankshaft and it should be perfectly compatible with what you have there.
As for the 10-3 from memory that is concerned with the accesories drives on the rear case i.e the 10-1 didn’t have an engine generator -the 10-3 would have provided this . There is also the issue of an engine driven vac pump which I think is another feature of a 10-3.

Thank you very much David,
You seem to know you engines very well. If I can pick your brains a little, what is a series 10-3 then?
Another question, what is the availability of the series 10-1 and or the 10-3? The reason I’m asking is that I just bought myself a new toy that will need one 10-1 and one 10-3! And it is not something I need tomorrow!! It will be needed in about 5 years time if all goes well.

Galdri- The series 8 is the military designation of a Gipsy Major 10-2. There is however the Gipsy 10-1 as well which powers the
Auster 6 and Terrier series. This mainly differs in having a tapered nose piece on the crankshaft whereas the 10-2 is a splined shaft.
There are also some differences in the rear accessories it carries.
I you want more specific answers ask away.

Hey,
That was a fast one!!! Thank you very much for the info. And JDK, I will for sure check out the Moth Club!
Again, thanks
Galdri:) 🙂

Hi,
I suggest you ask the de Havilland Moth Co: http://www.dhmothclub.co.uk/ All the Gypsy info one could want, and I’m sure they’ll help. If you have to join its 20 quid well spent, and you get to wander Woburn show for free (you have to pay to get in the park, but hey, it’s less than a fiver.)
Stuart MacKay is the main man.

the answer is the DH Chipmunk
while in military service the major engine installed in the chippy was designated the 8 but for some strange reason when civilianised the CAA redesignate it as the 10-2
