http://sceptreflight.com/Model%20Engine%20Tests/ST%20X.29.htmlSays 5 mm wrist pin , 6 mm crank pin . Which is pretty much ' V ' 60 ( stunt ) sizes .
Do you have a knackered rod , for the length ?
Ive just measured a G45 conrod , 5 mm & 6 mm . AND the ' COMO ' , which is the same .
As the Como is a development of the G40 series , as is the X 40 ( & 45 & 29 ! ) it looks like
ANY late G 40/45/51 ( & 49 ) rod'd go in .
This is where it started ,
and this is the ' schneurle ' .
21 series theres long & short rods . ( dual and single ring piston ) you got that with the 1960s G 40 / 45 / 51 too . So theres ones that go in , and theres ones the right length , that go in .
HooKay ; gotta Como 40 rod ( G 40 ) which is 34 mm center to center , as is the OS SF 46 rod , which is a 25305002 OS rod , for a " 46 AX , 40 - 46 FX . FXI .SF . VF Connecting Rod "
------------------------------------------------------------------------
Theyre6 mm along the crank pin - Como ( Super Tigre )- 5.95 . and the wrist pin ( both ). Whereas the OS rods 8 mm along the wrist pin . Gotta File .
as the OS rods a high output one , there ya go .
S Tigre's like OS . a rod of many colours , Er , FITS . Likely ANY ST Rod from the original G series and Late schneurle G-40 to 51 will be interchangeable . Some rear intake rods ARNT ' round ' at the disc interface ,
on the 21 series - 21/40 RV frinstance .
I accidently put the S T rod in the SF last night . CLANG . the outer big ends a gnats dik broader . SO the OS rod'll clear nosweat . But maybe youd avta narrow the little end as the lands in the piston might be less than 8 mm apart .
Other'n that theyre identical bores and length between centers . A VF .46 rod , in fact . see Part No. above .
