I know this is abit broad topic.......
Since the inception of this engine and other Gasoline engines that were made in attempt
to satisfy a Gasoline pattern engine, I kept thinking that there needs to be some
radical change with engines in order to be light and powerfullenough to
work in the highest pattern contests.....but something occured to me....
Just change the rules!!
If F3A, is to Formula 1, as to 1/8th scale onroad r/c cars....Why don't they just change the rules
to accomidate the gas engines?? They did it with the 4-strokes?
It is for there reasons why IMAC has gone way above and beyond the entree's and the technology??
Not much going on in pattern...
Where the Governing Pattern body wants to take themselves, not sure, but either they change with the
times (perhaps add a class of planes, or let the planes be bigger, and heavier) or they will
be soon called the Jr SPA...
Has anyone had a chance to compare notes with this SAP180 to the DL30?
As I discussed initially at the start of this thread, I purchased a Mintor 37 cc and sent it back...couldn't accommodate the funny angle of the carburetor on the side of the crankcase. The side exhaust was thought through and Mintor does have a return to center header and a very nice aluminum pipe that would probably work well with the 30-40 cc engines.
I've taken a very quick look at the DLE and decided not to purchase one. I don't care for the side mounted carb and side exhaust. Besides that, performance wise, it may be pretty good also. What it's table manners are and how it behaves long term, has to be seen....I know the table manners of the Syssa are excellent, on par with glow 2 strokes (on rather limited runs, I need to add so this may change over time), but don't have a clue on longevity.
Todd Syssa discussed with Ed and I his design philosophy as to why he chose certain materials (a steel rod, for example, rather than aluminum...or needle bearings on both ends of the rod....or, quadruple sealed bearings up front, etc etc), and I must say that sold me. After flying the engine in an overweight and oversized Pattern model, performence sold me again. To me, there is no need to change any rules to accommodate anything.
A side note, the bores and strokes of the DLE and SAP engines are the same.
