hi guys,

Im interested in either the CMP Zero 120 http://www.cmpairplane.com/warbird/Z...20%20Size.html
or the CMP F6F-Hellcat http://www.cmpairplane.com/warbird/F...20%20Size.html

Will the SAITO 20cc 4-stroke gas engine pull these planes, im really leaning towards the f6f. The engine manual i saw online says 0.60 - 0.90, but since im after scale flying and fuel economy would it be ok in a 0.90 - 1.20 size the weight is 4.6kg so around 4.9kg with this engine im guessing.

I also have access to a MVVS 26cc. What do you guys recommend, but i would prefer to use a saito.
