four star 120
Ok...ive made up my mind and im not looking anymore, picking a four star 120 for my second plane. Now i need an engine for it, i did a search and saw that some put saito 120's up front. I'm used to 40-60 sized engines, and i know what ones are good there...but i want to know what would be a good choice for a 120 sized four star. I dont care if its 2 stroke, 4 stroke, or a small gas engine...just something that is low cost and of good quality...if i HAD to pick i would go with an O.S....and a 2 stroke becuase they are cheaper.
any help will be much appreciated
and thanks in advance

RE: four star 120
I built a 4*120 and made it a twin. Lots of work and re-engineering, but it flew great.
If I were to build one today, I would go with a Zenoah G-26. It is a superb little gasser and can be had for less than $300 new and has a muffler and mount included. And......is way cheaper than glow to run.

Dusty,
I agree with rcdude on this one. The Zenoah G26 will be a great engine for the plane or even the new evolution 26T allthough the zenoah will be cheaper since it comes with everything you'll need. A big glow will be a fuel hog where as gas will allow LONG flight times and you cannot argue the falt the 3.00 buck per gallon for than outweighs the 15 -25 bucks per gallon for glow
I have the RCIGNitions G26 which is a stock G26 converted to electronic ignition turning a Mejzlik 18X6 prop in a GP Super Stearman weighing 15.5lbs and it flies it very very well

If you're considering gas, why not look into a converted weedeater engine? Scott Ellingson is apparently doing a good Toro 25 cc conversion for $ 155.
I've got my eyes on the SR Batteries Eindecker and that will probably be the engine I go with when I pull the trigger on it.
It looks like a good economical choice for a sport flying plane.
Here's a link to his web site: http://www.scottellingson.com
Hope this helps,

WOW!...thanks for that info...thats pretty cheap for a gas engine...and its lighter than a zenoah gasser...I am definately looking into this one.
Thanks again!

RE: four star 120
The zenoah is more expensive than any of the other weedie type engines in the 25cc class. It is also a good bit more powerful too. The boost port in the G-26 cylinder is what gives it such a advantage over the G-23 and other engines with tranfer ports only. I think it out run the toro by 1000 rpm give or take a little. I tached my box stock G-26 yesterday and got 8700 with a 17X8 prop.
The toro is a fine engine as long as you don't require power of the G-26

No question about the greater power of the Zenoah. What has me looking at the Toro conversion is the fact that for a sport flyer that doesn't need more than run of the mill power, the savings is worth it.
If I were looking at a competition plane, or an aggressive acrobat, I would be looking at top of the line engines.
For a more basic kind of flying I think a good conversion is appropriate technology.

RE: four star 120
What prop were you running on the G26. APC or somthing else. The only numbers I have to go by on the G26 are Horizons number of 8900 on an APC 16x8. I have had a new Toro at 8550 on that prop. It would be interesting to see what it does on the prop you used. I never like the numbers given by the mfg. I like to get real world numbers. Also have you tried an APC 16x8. If it is at 8700 with a 17x8 it may even go better than 8900. It is just nice to compare.

RE: four star 120
Yes, a APC prop. I have not tried a 16X8 but I'll bet it would do better than 8900. My engine was put into service this past spring and has had 5-6 gal run through it since. It has picked up about 200 rpm since new. The 17X8 has worked very well on my ultrastick, so I have not tried anything else.
I have a 3W-24 that I have not yet run but I expect it will be slightly stronger than the zenoah. It's not an inexpensine engine though by any means.
