I am new at this game so hope I am posting in the right place.

I have a DP Ultimate with an OS120 four stroke on it and was wondering if anyone has but a Saito 150 on it? I have read some threads on this subject but have not come to a positive conclusion. Hoping to get some help from other DP ultimate 120 users.

if yes what was it and how did it perform?
prop size?
fuel tank size?
Thanks for any information.

Hello Listed.

I have a YS 140 with a 18x6 prop and a 24 ounce plastic soft drink bottle for the fuel. Love this combo it will hang and torque roll and knife edge for as far as I can see has great power to weight ratio.

In nut shell I am all smiles when it is in the air.

Running a Saito 1.8 on mine. Thinking about trying my YS 1.20FZ... I dont know if I would go with an OS 1.2?

Hello Otter........I have as YS120 on a 1/4 scale clipped wing Cub. Does really well with scale flying. You know with all that wing and drag. It looks real. With my experience YS engines give you lots of power quick. Winds up really fast. Also YS engines have the highest horse power in their size. They are a bit pricey but they have saved several planes with their immediate response to the throttle. They were designed for pattern flyer's. Constant power and pull if you know what I mean.

The plane that gets my heart throbbing is my Tiger 60 with a YS 140.

Thanks to everyone for the information about powering my dp ultimate 120. I believe I will be looking into get the YS 140. it is big bucks here but maybe worth it. I have the OS 120 on the plane now but I feel it could stand a little more power.
Again thanks

Look at the YS140FZ, which is also called the 140 sport. Significantly more power than the OS and is about $440 US at Central Hobbies. A little more than the OS120 pumped but not that much.
