Is it fair to say that this plane will be underpowered with an OS 120 III pumped 4-Stroke? The ad states, as meantioned, 120-184 FS. Knowing it is significant diff in power output btw the low vs high end engine size. Is there anyone here that has experience flying this plane with a 120 FS? Also the ad claims a flying weight of btw 9-11 lbs. Knowing this is a full kit, is there some fairly easy ways of making this plane lighter so it actualy comes in at 9 lbs? I had a GP Extra 300 .60 before and its weight was 8,37 lbs. Considering its performance I know I would not like an aerobat being hevier than 9,5 lbs using with my OS 120.
Hoping for som advice as I am searching desprate for an new Extra. I know abot CG and other makes as alternatives but are now researching this kit.

Regards,

C.
