what size gas or nitro engine do you use for your Katana? I used a 26 cc RCGF and my plane was under powered.

Just had my CMPro Katana 140s maiden flight yesterday. Good flight but a very windy day. Just flew it one time. Needs more engine down thrust. My CMPro Magpie 50 did not fare so well in the wind. Engine died upwind of the runway. Had to land it with a strong tailwind so it came in hard. The body took a beating. Repairable, but not a one or two day job.

nice flying, but it looks a little underpowered. I may get one and put a Moki 180 in mine

you have this exact Katana with a 140? I’m thinking of putting my OS 160 in one. This video plane seems to lack power and moves a little bit like a weak electric.

Yes I do have the exact same one, and I do have the OS 160 in mine. The title of this video says 120 but I think is should say 140 as that’s on the box I have.

Moki 180 in this video is a Gas engine and for what I know about Gas engines they are no where near as powerful as the nito engines. You will love the power of the OS 160 which will easily hang this plane on the prop.

The plane to me was very tail heavy. Right now I temporarily have 14oz of weight under the tank and may add more.

Thanks for the info. What is the total weight of the plane with children? I’d like to stay under 12 pounds.

With the all the gear in it and the 7oz of nose weight it came out to about 12lb 6oz. So without the nose weight it would be 11lbs 15oz. Since I weighed it I did add another 7oz. So in s nut shell its current flying weight is 13lbs 1oz..
As I recall I did find others that said it was tail heavy out of the box so do a more research on that, RCUniverse is a great place for info.

Over the winter (NJ) I will probably make a 14oz block weight and mount it up under the engine block.

Super model. Rozbiłem taką przy pierwszym starcie z silnikiem DL 50.
