Not wanting to start off another Saito vs YS debate here but I would like some suggestion as to the best motor for the 140 sized Giles 202 from CMPro (or Flair in the UK).

I am leaning toward the Saito just because it is larger and probably a bit more powerful then the 110, perhaps. I know both motors are good, I own a few Saito's and YS but neither of the two mentioned. A friend of mine swears by the 110's and has a few now and has never had a problem.

So is the Saito any better due to its increased size? Is there not much in it? Any thoughts or suggestions?

Thanks,
Andy

Andy: Go out and watch your friend,s Saito 110 and then lets us know what you think. Capt,n[:-]

Opps might of given the wrong impression there, I meant he has a few YS110's now in his models and rates them very highly. They are very powerful!

I'd stick an Evolution 26GT on it. To heck with wasting time scraping all of that glow goo off a beautiful model. <G>

Id say ys 140 or saito 180. In my opinion, this airframe is too small for the heavy gassers.

andyjayh

Hi Brian, so you think I might be under powering it with these two engines then?

Cheers,

Not sure where you get your info but the Evo25 weighs only 2 oz more than the Saito 180. Doesn't sound so heavy to me.

You should check out the other post on this plane. There is a person flying this with an OS 120 FOur stroke. I don't know your flying style. I personally like to fly my planes with a motor on the upper end of the recommended power range.

Most of the glow setups I have seen on this plane are around 10 lbs to 11 lbs. Most of the gassers I have seen are 12+. That is where my info comes from. I did look up the evo motor on horizon. It says it is 33.6 ounces. But, it says that is engine only. By the time you add all of the accessories needed for this motor, its hard to say where it will end up weight wise.

I also like to have ample power in a model so I can call on it when needed I have seen one of these fly on an ASP120fs but only just! This is why I was asking the question as to whether these two engines were right for the model. Both are more powerful then the 120 sized bangers but wasn't sure if the Saito had the enge on the YS due to the size increase.

I would like to go for the YS as I know they are nice motors but is a YS110 enough for this size model? Is it worth the hassle of another type of fuel to the flying field? Would the Saito 150 have the edge and be more conveniant at the same time? Or should I go for the YS140 or Saito 180 as suggested now????

When CMPro sys 140 it means the YS140!

andyjayh

Good answer

Right I'm getting the feeling that I have undershot on my engine choice then. Seems like I should be choosing between the YS140 and the Saito 180, that's if I don't go petrol [8D]

I have this plane and I understand you wanting the right engine. I have been doing some research on the new light gas engines that have come out. The weight is down and the power is up from what they used to be. Gas motors used to have a very poor power to weight ratio, but that is changing. I have a Brillelli 25GT gas engine in mine and it spins a APC 16x8 prop at 8400 RPM and she is not totally broken in yet. I am not a 3d flyer and my Brillelli flys this plane pretty well for my type of flying. If you want to do 3d flying I'd stay with the Saito 180 or YS 140 four stroke. But if you just like to do pattern type stunts I'd say try a new small gas engine that weighs in the 2lb 4 oz range like the SPE-26 from BCMA engines or the Brillelli 25GT w/ei. Both of these engines will fly this plane very nicely and save you some money you can spend on things you'll need to set this bird up. Here is a short video of my Giles-202 with a Brillelli 25gt w/ei. enjoy and good luck.

Jim is right ... I just got my 1st gasser today, its a mere G26, I do see how cheap they are to run and it will find its way into a scale plane for easy flying. Small gassers are powerful nowadays, my friend's G26 is giving the same performance as Jim's 25GT.

andyjayh

Thanks guys for this info. I have been chatting to some guys on another forum and they are saying the same thing, go gas

The engine I have started to look at is the MVVS 160 petrol, weighs around 950 grams and produces around 3hp. Not sure how that translates into thrust though. Do you guys know anything about this motor? How does it compare to the G26 or the Brillelli 25GT?

If I go down this route then it will be my first experience of petrol so I will be a complete novice with these engines. I assume they are far better these days so that shouldn't be a problem. I have to say that I am surprised to be thinking about petrol with this size of model, I always assumed I would need a larger model to go petrol

There is a guy from Slovenia that has The Giles-202 140 on a MVVS 160 gas and I know it has more power than a G26 or a 25GT. It also has a higher price tag, but if you where going for a YS 140 or a Saito 180 then that will not be a problem. Once you go with gas(Petrol) you will never go back.

Here is the link. He is post#59 and has a link to his site I think on post#63

Good Luck

Save the gas engine for a 80 inch plane and up.The Giles is designed to have a 2 pound glow motor.If you want to put on an airshow go with the YS 110 -140 or Saito.The Giles is light.The YS 110 will hover it.I run an OS 160 2 stroke, and the plane is unlimited.

andyjayh

Hi Jim, thanks for the info. I think I have seen some posts from this guy in the past but I can't find them again now, do you have the links?

Many thanks,
Andy

andyjayh

That's interesting to know that you get such good performance from the 160 2s. It has been an option but not one I have spent much time thinking about. What prop do you fly on? Is the model capable of hover with that motor? Not that I can do hovering yet but it is a good indication of grunt grom the motor

Cheers,
Andy

Sorry I did not post the link. I thought I had, but I messed up. Here is the link.

http://www.rcuniverse.com/forum/m_31...2CGiles/tm.htm

Post # 59 shows the plane running and post# 63 has a link to another site in his country where he introduces the plane. It is written in his language, but has a lot of pics on the build. He also uses a tuned pipe on his MVVS 26 gas engine and a 18x8 prop. A gas engine may not hover this plane and if that is what you are looking for say with the nitro burners. But if you just want to fly a very nice plane and do pattern type stunts the small gas engine will fly this plane very well and save you money on buying one and running one.

Just my opion.

I Love Gassers

You can expect this type of performance woth an APC 18x6W at sea level with an engine that is barelt broke in.

Nitro wing: That plane sure looks good in the air. That take-off shows it has plenty of power. Your style of flying is a lot like mine was. I love landings and touch & goes!!! Don,t let anything happen to that plane. It is a keeper. Also some very nice video ....thank who ever took it. Take Care Capt,n

It doesn't take much to get hooked on gas engines. I also have the Brillelli 25cc GT/EI but haven't flown it on a plane yet, just on a test stand. I have the Giles 202 140 that its going on bust just can't seem to find the time to finish it. Not only do the gassers look cool, they sound great also.

captinjohn

Well I just got my new glasses and the work bench is about done. I will be starting to put my Giles 202 together soon I hope. Capt,n

I shall be going the Saito 150 route.
I like to fly 'scale ' type sport manuvers so i'm sure this combo will be more than enough for me.
Kit and motor still NIB so no experience with it yet.
