You will be fine with the 120.....If you were looking at buying a new one I would say get a 140.....but the 120 and the Typhoon will serve you well for a lot longer than you have the plane....I'm talking you can honestly compete and fly that setup for many many years and it will work...


Build the Typhoon light light light....


Buy the good 4-6lb balsa it makes a huge difference.....AND be careful not to use too heavy or too strong of components and structures.....The 120 will haul it but it will need to be light as you can do it.....a 10lb plane will like the 120 a ton better than a 11+lb plane and the typhoon can get heavy in a hurry....so beware.....take the lightest route when building and making decisions....

If you are 10lbs I bet you will be very happy with the 120 in it....not the absolute best setup for power a YS 140 Sport or 140L or the DZ is optimal but the 120 is more than adequate.

If its at 11lbs you will not be happy with the outcome...even on 140 sport you might not like it.....And the DZ is the king then.....


Good news is all the 120's and 140's are drop in replacements so you can upgrade later...the 140's are built from the 120's and the 140DZ is an upgraded 140...the DZ has a minor requirement of about an extra 1/4" behind the carb for a fuel fitting that sticks out there but all in all its all the same dimensions....


Good Luck
