Back when i built mine i recieved a NIB saito 180 in a trade deal. I had considered it for the US Lite but sold it here on RCU as i knew it was quite the thirsty engine, the funds i recieved for the engine and a little more out of pocket set me up with the Brison 2.4. 1.50- $2.00 a gallon for gas and not having to de-slime after the day was worth the expence! It has ridiculous power, however a have read reviews of this plane with the big saito up front and they said it is quite the performer..... Just think of all the weight savings! It should be a blast, will be looking forward to hearing how it flys. Good luck!
