Default Icepoint 77.5" WS Pattern Plane

Just got my hands on this airframe and would like to know which 4 stroke you guys recommend. I also got my hands on a Dream 110 with a YS 110 (I believe). The Icepoint has everything but engine and fuel tank so I need advise on the engine size and tank size. I will prefer a Magnum, OS or Saito as I do not want to deal with another YS. So Im thinking maybe a Saito 150 or any 120 if it provides enough power for it. TIA

Best regards
Ed

Hi Ed,

Really depends on what type of flying you intend to do. For pattern, depending on what class you fly, it may struggle with any of these engines. Even the Saito 180 only turns a 16 x 8 prop. You may even find it will fly too slow for that design? The plane was designed for a YS 140/160, which run a 16.5 x 12 prop at around the same revs as the others.

I'm interested to know how it goes with whatever engine you decide on.

Well I pulled the trigger on a YS 140FZ. Thanks for the advise. Now I have to shop for a motor mount and tank, so if you have any suggestions, its appreciated.

The FZ is more user friendly than the DZ's and should be a good match I reckon.

I use Tettra tanks and haven't had any problems with them., but K&S or MK would be good too if you can find one.

As for engine mounts, what type is the plane set up for? With or without a nose ring? Firewall or beam mount?

Looks like it's set up for the YS Super Mount.

They are an excellent mount.

The MK floating mount may work as well if you had one. A bit hard to come by now though.

I absolutely love my DZ 140 but Drac is correct that the FZ will be easier to set up and close to the same power as the DZ. that being said my DZ is mounted on an airplane that honestly is a bit of a hangar queen and does not see that much flight time. I brought it out on Friday for the first time in 6 months and she fired right up and needed no adjustments. Between Friday and yesterday I logged 6 flights without as much as a missed beat. I run a 16x10 three blade CF prop and 30/20 all synthetic fuel.

I reckon you'll find a 16 x 10 3 blade will be too much prop for the FZ.

My first YS was a FZ140 around 17 years ago and from memory I used a APC 15.5 x 13N on 30/20 fuel mix - YS's love nitro.

You want to aim for around 8200 - 8500 rpm on the ground.

APC pattern props are much more efficient than other brands, as they are designed specifically for pattern. You may have to experiment with a couple of props to find the one that best suits the plane and your flying style, but that prop should be pretty close.

Will look into APC. I want to start with a "mild" prop (something that wont make the plane too fast to land) until I get used to it. This will be the my first time flying a 2M pattern plane (although I have flown a couple of 40-60 size pattern planes). Thanks for the advise, as usual its appreciated.

The 15.5 x 13N is a narrow blade so shouldn't be too bad.

If you can, have someone there that has flown 2m ships. And until you get used to the landing speed, leave yourself plenty of fuel to give yourself room for a few go arounds.

Good luck.
