A very Happy New Year folks from a very chilly Charente in S.W.France.
Advice please regarding the expected launch RPM of my 'older ' engines.
I have several older engines , which are usually run on a fuel mix of 25% lube' , usually 18% castor , 7% synthetic with 5% nitro. I am using MAS 10X6 props' and uniflow R/C plastic tanks. I am also using tongue mufflers.
My 'best/reliable' launch RPM's are as follows :
ENYA 35 [ 5224 ] : Around 9,000.
OS 35S : Around 8,800.
Fox 35 [ 40th and 50th Anniv'y ] : Around 8,600. [ With all castor 27% ]
Do these appear about right guys or should I be expecting someting better please ?
Much obliged for any contributions ,
Robin [ ex-pat Brit in the Charente full of ex-pat Brits ]
