Hello, I hope this thread is still being monitored. I am getting a V2 70. I have a new 75 2 stroke eng. Does this have sufficient power for the plane? 2.2 HP
Tnx Vince |

Re: Katana v2 70 with YS Engine
You will be totally bumbed if you put a 75 2 stroke on this airframe. It's not about horse power it's about torque. A Saito 100 would be good spinning a 16-4 Xoar prop. A YS110 would be "lookoutkids" fun. That 75 will never spin enough prop to make that airframe come alive. Just my opinion don't ya know. Be sure and beef up the fuse on that thing, they break real easy. CF tube works good.

Re: Katana v2 70 with YS Engine
the .75 will fly the plane fine. Wont have ballistic vertical, but it will be enough I think. Mine with a ST90 hauled arse, so the .75 will be just fine.
PS. this is a .70 size airframe. This is what happened to mine when the ST flamed out in a low hover..  and

Re: Katana v2 70 with YS Engine
Come on John; you don't put a slab together for it to be just fine, you do a slab to be "off the hook". If it has to be a 2 stroke I wouldn't go any smaller then a 91FX, the 120 would be "lookoutkids". I'll tell ya one thing, that 75 would never be probro approved.......................................... ........................

Re: Katana v2 70 with YS Engine
The question wasnt whats the best engine for this plane, it was "I have a .75, will it be enough." To get a 'bro' flying, you better believe its enough. When you can afford it get a .90 2 stroke, or a 100 4 stroke.

Re: Katana v2 70 with YS Engine
I would probably put a Saito 180 or at the minumum a OS 160 on it. That should make it come to life.

Re: Katana v2 70 with YS Engine
Was flying my Kat 70 with a MVVS 90 2 stroke. Never managed more than a 5 minute flight before the engine would cut ! Did any of you have problems with engine vibration, causing bubbles in the tank, causing the engine to cut ?

Re: Katana v2 70 with YS Engine
I tried a YS110 on mine and I could never get my YS110 to run right on the airframe due to how thin the airframe is. I switched the YS to my Fusion and the YS ran perfect. I put a OS 91 2 stroke on mine and it did great!
