ASP-specs
The latest 'Series ' engines (all 2 strokes are traditional ABC (4 strokes and 1.20/1.80 2 stroke are ringed) and all engines are twin ball raced) include many enhancements over previous versions;
* new crankcase design (with O.S. exhaust port sizes ensuring many silencer options are available)
* double bushed CNC conrods
* improved metallurgy
* new design (internal idle needle) twin needle carbs
(Rear Safety Needle optional at no extra cost on many engines)
* baffled (quiet) silencers (available for most engines)
meaning improved starting, reliability, power and long life; all at great value prices.
The massive range; 2 strokes from .12 - 1.80 and 4 strokes from .30 - 1.60 + 64cc radial.
All engines are provided with a 1year warranty (against manufacturing defect), Comprehensive English instructions (including running in and carb. setting) and Galtech Models Ltd full support.
