Anyone got a 46 engine to hand?

Could you take a few measurements off it for me if you do?

I'm after the distance between the backplate and prop driver face. I'm also after the mounting hole pattern (width between the holes, and the distance fore and aft between them too).

Cheers
Andy

hmmmm what you up to??

Try here bud http://www.osengines.com/engines/dimension-std.html
or here for metric http://www.osengines.com/engines/dimension-metric.html

my AX46 has backplate(bolthead) to prop driver as 85.2mm, hole centres 17.5 x 44, 3.7 dia. I'll send a photocopy of the page to you, not sure how to do it here, can we have another lesson on sending attachments to the forum please?

Cheers Ian, much appreciated!

I'm just tweaking a design about slightly, to get rid of the nasty IC engine, and put an electron burner (as the actual God himself intended)in there instead. Need to get hold of a suitable motor to replace a 46 now, using 5s lipos....

and the plane is a ..............

It's not strictly a plane.....

TUT! just tell me


Ian,

we currently can only host pictures ( jpeg gif,tif etc), atachments like excel, PDF etc etc cannot be done

If pics your after try here https://rdmfc.forumotion.co.uk/general-discussion-f1/how-to-post-a-pic-t22.htm

If anyone's desperate to post a PDF file, providing file sizes are not enormous I could host the file on the club site and link to it from the forum as I've done with the trim chart and associated article sorry for drifting

Ok I've got photobucket and loaded the image, didn't find the size selector. Most photos on the forum seem to be attached to the text rather than as a link to say Photobucket, I'm missing something ( grey cells) or there is another (better?) route. I know I'm digressing but I think the original topic has been dealt with.
The link for my photocopy of an AX46 is https://s620.photobucket.com/albums/tt288/Ianto_bucket/?action=view&current=ax460003-1.jpg, I wilol be interested to see how it comes out!
Ian

and here it is

Hi Ian
Once you have opened the page in photo bucket where you can see your pictures
highlight the descriptor img (4th box down) it will turn blue when you put your cursor on it
tThen right click "copy" hen return to the forum where you are creating a new reply entry

Type in your text and when ready "paste" the picture in the text

All you see is a garbled text

Preview the post and you should see the picture
and the other one
point, right click, copy
and then paste

Andy
There still are big dimension discrepancies between makes, particularly the ones you describe.

OS, in particular, standardised just these dimensions :-
Prop driver to first hole, front to rear hole and width hole spacing got standardised. Nothing else was standardised.
All their 40 class 2 strokes starting with the OS SF 40 and 46 series kept to these settings
Exception
The FP range which became the current LA were much shorter and narrower.

SC and Magnum tended to be very similar to OS, well they are effectively copies.

Other manufacturers reluctantly went along with the idea but many didn't really bother to take it on board. In particular Super Tigre, MDS, Irvine, for quite a while and Enya are still "different"

Damn nuisance but

Cheers guys!

I only needed approximate dimensions, so all is good

Andy

Oh im a bit late tbh, and I have a OS .46 engine, but as you have all the specs I think you no longer need me to say anything.
P.S. that solder works a TREAT!
Much much better than that old thick lead free stuff I was useing before!!!
Thanks you VERY much
