LOL what are you guys smoking the DLE doesnt make more power.
You guys post your Honest number on the DLE 20 with props and i will post mine.
Bone stock OS 120AX with no baffle in the muffler with out extension will turn an APC 16x8 uncut prop at 8,600
The 16x8 is tha max load for the OS though.
where guys think the DLE make more power is that it is better suited to turn large props that make more thrust with less speed. the OS will turn a 18x6 ZOAR also but i dont have a number for you. I will mount the engine on the test stand if have to.
If you really want a more power then just get the DLE 30 for that plane. you will not notice that much more ''power'' with the DLE 20
Also the OS 120 will also spin the 16x8 APC at 9,600 with the Jett muffler.
So to save the most money just buy a Jett muffler for 80 dollars and throw on that 18x6 i think it should spin it around 9,000 or more.
