I would think OS will give you marginal power. You may need a little bigger engine if you need 3D power. 1Oz difference is very acceptable.

Reza: Does anyone have tried a gas engine in this plane, like evolution 26 o 3W 28, I want to buy my first gasser and think in the 86" yak, but the size is to big to carry in my car, so I think this would be a nice plane to own. I'm pretty sure that with a glow engine this is a fantastic plane, but I'm worried about the price of the glow fuel. Thank for your response.

A friend of mine has a Saito 180 in a FuntanaX 100, and it has an awesome performance. The glow fuel consumption is not as 120 AX (much less) and the vertical performance is amazing. I think this engine would be excellent for this plane. I'm thinking about getting this combination.

I haven't tryed gas engines but I don't know if they are more problematic.

Regards

Jorge Medina

This plane can't take a gas engine. Vibration will kill the plane Sorry.

Thanks Rezagh, so in this case, which would be the best 4 stroke glow engine for this plane, my flying site is 980 meters above sea level. Thanks for your response again.

Status: offline 		Hi Jose,

Yes a two or four stroke either one would do the job. If you are only flying the plane for 3D, I would recommend a 4 stroke otherwise, an OS1.20AX is also very 3D capable engine and once it's broken in, it will give you a great torque and punch.

At your altitude, you should be fine with either OS 1.20 (rwo stroke) or Saito 1.25 or YS 1.10.

Thank you,
Reza

Status: offline 		O.K. Reza, thanks for your response. Do you have any idea when the plane would be available?, I check QQ website and it only say late june. Also, what type of servos will be the best for this size of plane in particular, I fly with futaba and prefer this brand and finally, for the saito 1.25 wich would be the most adequate propeller. Thanks again.

José Antonio Rivera.

Status: offline 		Hey Reza, I may have plans for my YS110, would it be too heavy if I put a YS 140 or one of the new 170s on there? It would only end up being 3 ounces heavier than the 120 AX. Would this extra weight kill the performance of this aircraft?

Status: offline 		seeing how this thing performs with a heavier engine than mine it should kick some serious @$$, Ill be using 5955s in the tail and 5925s on the ailerons considering that the rons don't need as much holding power, if they do I will get two more 5955s. That YS is a real stump puller on 30% so it should be fine.

Saito 125 is a an awesome engine for this plane

JR3D,
5955 is way over kill, 5945 should be the perfect match I guess you will be fine with 5925, as a matter of fact, no guessing you will be fine with 5925

Thank you,
Reza

Status: offline 		THis plane is about the same price as the 73" but you can get by with a much cheaper power supply. Wonder how the flight performances will differ between the two?

I had a Funtana 100X and did not like the way the tail feathers where built, or lack there of.... I am intersted in how this plane flies....
ANyone flown this yet? Is there any pulling or are the rolls very axial?

I had a 120Ax in the Funtana100X and thought it had lacked pulling power, especially out of hovers..... Others said the the 125 saito was not very good either.... But then it was stated by another person that he had a saito 125 and sold it for a 120AX and he loved it...

I had some damage to my plane and then repairs, so it is possible that it was these repairs that caused it to have more wieght and therefore it didn't have good excess power....

I think most would want a saito 180 in this plane, so that you could get out of troublle when you needed to ....

Just my thoughts

Justin
