RAN IT FOR THE FIRST TIME TODAY, AND WOW! IT IS EVERYTHING I HEARD IT WOULD BE AND MORE. TURNED APC 18X6WIDE 9400 RPM WITH THE RICH 2 TURNS OUT FOR BREAK IN. NORMAL WOULD BE 1 - 1 1/2 TURNS. SO THERE IS MUCH MORE RPM TO COME. IT TURNED 8500 AT HALF THROTTLE. I WILL KEEP IT BETWEEN 8000 - 9000. WILL TRY A 19X6WIDE. I WILL USE IT IN A 3D APPLICATION. I USED MAGNUM #1 FUEL.

I DID NOT HAVE TO USE A STARTER, JUST FLIP IT A FEW TIMES WITH THE THROOTLE WIDE OPEN, BACK TO IDLE AND BACK FLIP AGAINST COMPRESSION. SATARTED AS EASY AS MY SAITO 100 DID. I USE A PAINT ROLLER COVER FOR MY CHICKEN STICK. THE VIBRATION IS VERY LOW. BREAT ENGINE!

I am going to use a wide blade 19/6 also on my dz the 18/6 turns at 10,000 static which is a little high glad to hear you like the magnum fuel i told you so HA HA you might give buzz a email or call and tell him the results he wants to know and will talk at length about his fuel and the DZ . Very knowledgable gentleman who makes some dyamite fuel for any 4 stroke by the way Earl i answered your private message on the turns out on high end About 1 and 1/2 max .

I CHECHED THE APC SITE AND THEY HAVE A 19X8WIDE - WHO HAS AN EFFICIENT 19X6 WIDE. THE APC IS HARD TO BEAT FOR PULLING POWER.

Earl sounds like you happy with your motor.I just recieved my 140DZ just wondering on your nitro content .I see alot of people using the APC prop I thought that a lighter prop was preferable for 3D so I thought wood ,what's your take.The APC is a great prop but I thought it's on the heavy side.Soon as I get my prop and fuel I'll be bench runing also.Thanks Andre

IT HANDLED IT LIKE IT WAS A TOOTH PICK. INSTANT ACCELERATION FROM IDLE. APC18X6WIDE. NONE OF THE WOOD PROPS I HAVE SEEN CAN MATCH THE DYNAMICS OF APC.

The heavier the prop is for a 4 bangar the more they like it they idle better on a heavier prop the apc wide blades are awesome on the YS140 DZ glad you like it Earl i am looking for a 19/6 wide to but apc doesnt list it on the site only the 18/6 .
