7.50cc ABC, Twin ballrace and a neat twin needle carb, front or rear main needle {1}.
Supplied with JENS3/37 quiet silencer, JENS3S/37 super quiet silencer available for only £5 extra.
Latest ASP .40 and .46 'S' series engines are very 'O.S. like' both in terms of their looks (and size) and now performance!!
Thanks to the re-designed (and timed) liner and carb., performance is now among the best of any of the 'sport' engines.
In our tests (
using standard 17% oil, 5% nitro fuel), the baffled (quiet) silencer,
O.S. no8 plug and APC props, the .46 following a brief 15 minute running in period recorded a really respectable 11,500 rpm on an
11x6 and an awesome 13,500 rpm on a
10x6!!
Beat that for 'power to pound' (power to dollar) ratio!!
What does the 'S' stand for?........ Super, Special, Stonking! - or you can you think of one? ;-)
{1} Main Needle can be fitted to the carb, or to a rear needle mounting bracket which is supplied as standard with the engine, giving the choice of front or rear mounted main needle valve.
"It runs perfectly and has never missed a beat. Pick up from slow idle is steady (typical 2-stroke) and always reliable (not typical 2-stroke!). Power is excellent" - Customer Comment. "
