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?

Beam mount, nose ring

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.

Thank you, will look into those.

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.

What a beauty
 

Nice! What brand of prop? Thanks

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.

Thanks Drac1

I have a Odesseyes II with a YS 140 sport. I'm using 13% nitro 20% oil. The oil is made up of 85% synthetic 15% castor Morgan's oil. Turns a APC 17x10N @ 8200 rpm. Flys Sportsman awesome.

Undecided
 

I have never flown e power and have no idea on how to go about it. Although I got the YS FZ140, most everyone I fly with suggested e power.
What would be a reliable motor and esc? What kind of lipos would I need? And last but not least, how much would a set up for the Icepoint run me? Thanks

It's a great flying airplane. I run a DZ 170 on mine, it pulls like a tractor.

Since you already have the YS I would stick with that. Once tuned they hold their tune really well. Initial costs of an E setup is fairly high but a good plug and play setup would be the Himax 6330-210 pro motor with a Castle Creations HV 80 amp speed control. You would want at least 3 sets of batteries. Most guys run dual 5 sell batteries of 4200 to 5200 mah. For a glow conversion I have found you really need the weight of the larger batteries. Here is my latest glow to E power conversion. An old Chip Hyde Hydeaway. Power is an AXI 5330 F3A motor with an OS HC1100 controller and Falcon 19x13.5 prop.

a side note on prop selection with your YS powered Icepoint, the 140 what tuned well will idle down quite nicely. You shouldn't really have an issue with slowing the airplane down. To a certain degree CG can influence landing speed just as much as idle speed.

Any pics?
 

Would you mind sharing a couple of pics of your engine mounted? Would like to get an idea of how its all set up. Thanks

So far I have run YS 53, 63 91 and just starting on a 120NC. The first three have been run extensively with very minor adjustments to any of the mixture settings. My 63 is approaching 4 gallons of fuel with zero maintenance and only adjusted the high speed mix when I flew it on January 1st (25ish degrees) this year and last, then back when it warmed back up I NEED to check the valve adjustment. It is starting to start a little hard and the idle mixture/speed is starting to vary a bit so it has to warm up a bit longer to run correctly. I suspect it needs a new diaphram which I have on hand.

I guess what I'm saying is use the 140. The YS's are a little different but once set up they rarely change and if they do change they usually give you a warning that some maintenance is needed. As far as fuel is concerned I burn Sig 2C 15% nitro. This is a 50:50 mix of castor and synthetic oil. Yes you will have a little more carbon to deal with but I'm happy. IMO any "GOOD" fuel is suitable as long as you have at least 18% oil. 20% is better if full synthetic.

PS, I think I just started a fuel war thread. LOL You will get many opinions on what fuel to use. If in doubt, follow the YS manual.
