I will start assembling my Swallow EX this weekend and I have to decide what engine to use. I was plannign to buy a new YS91FZ from Central Hobbies (don't want to pay the overpriced 110). The 120 is no longer available, and the price for 140 sport is really good (about $450). I read the review in RCM&E and the reviewer said the YS91 they used was "just adequate" and that it would benefit from a 120. Is the 140 Sport too much for this plane?
Better yet, anybody has a good condition 120NC or FZ for sale?
