The recommendation is 160 2-stroke. (180-200 4-Stroke).
 
I flew mine with a 1.20 four-stroke and it was fine but if it's speed you're seeking then a 1.50 four-stroke or larger is the way to go.

HI Lee, 
 
Yes i know it will be lower compared to the four stoke. the 120 is 2.1 compared to 1.7...
The reason i asked is because i saw a video with someone flying it on the G20 and i trust those who are wiser than me to guide me to the best option and i am still learning so its better to ask than be sorry.. cheers

Hi Lee, 
 
I emailed Horizon hobby, and this was their reply "This plane can take up to a 26cc gas engine the G20 will work for the plane"
 
Cheers

yeah i am sure it will "work" on the plane but would the power be a bit marginal and result in you flying the entire flight at near full throttle, its not a nice feeling that!  if you have the extra dosh go for 26cc

The plane came with CA hinges... What do you guys think of CA hinges on a model this size? Thanks Cheers

I think that the z20 will be more than big enough for this model. Regardless of the numbers, I would say that it way outperforms a 120 fourstoke and its clean, clean, CLEAN!!!!  No more dreadfull gunge all over the model after every flight.
 
The z 20 is a quite wide engine, the carb sticks out of one side and the silencer is on the opposite side. This is more likely to be a deciding factor .

use a good 120  or tt130 and you will out perform a z20 on std exhaust i know i have both as for clean sort of agree but he tt130 has very little output keeping in mind this is a racer i would still go for either a 150-180 four stroke or a 26 to 30 cc petrol (they are easier to start and cheaper to run) but at the end of the day its up to gazz and all engines will fly it fine, its just up to him what he wants it to do !
