Hi,
I concidering using gas engine on my Zen-120, the question is whether there is Gas engine with similar moment curve as OS RX-140 ?

Thanks

The SAP 180 should fit that application

selnekav

yes, i thought about the SAP-180 or DLE-30

i guesss the SAP with the standard muffler ( including the tons to reduce noise ) will have enough overall power for that model

with the muffler tons i guess 16x10 or 17x8 apc will be ok.

17x12 std blade, 18.1x10 std blade, 17x10 std blade, 15.75x11 3 bld, 19.1x11 std blade, 18 X 6, 18 X 8

The DLE 30 is more of a torque engine but it would have comparable power to the 1.40 also if propped correctly

selnekav

for my application i afraid that the DLE-30 will be overpower. (The Zen is 180x180 so it's not full 2 meter )
what about engine vibrations do you see diffrence between the two ?

Maybe the DLE-20 would be more for your needs?

17 X 6
16 X 8
15 X 10
14 X 12

i think the DLE-20 will be underpower, pepole are using RX-140 on their Zen

The Syssa will give you a much better torque curve for pattern than the DLE will give.
Both are good engines but from what I have seen, the SAP 180 is a better choice of the 2 for pattern applications. It doesn't have the same top end RPM's or flat out horsepower as the DLE but it is a very sweet engine in the mid range.
