|ASP 0.52 S|
| Introducing the latest ASP 'Series 3' - the .52 's' long(er) stroke engine.|
1.75HP @ 17,000
Weight inc. carb and 'Super Quiet' silencer (pictured) 500g
Thanks to the totally new bore and stroke, re-designed (and timed) liner and carb, performance is seriously impressive for less than £100.
To prove our point (and to get independent results) we asked local engine expert Mike Thompson (BMFA Area Examiner) to test the .52 'back to back' against the most popular .53 (in 2002) - the Irvine .53. His brief was simple; take these 2 new engines, run them in and test them using the same fuel, plug and APC prop(s) on the same day!! Can't get fairer than that!!
In the tests (using standard 17% oil, 5% nitro fuel), O.S. no8 plug and APC props, after 15minutes of 'running in' (on both engines) the following performance was recorded
and that's a lot of power for an engine in the same size casing as an O.S. 46FX !!
