Thank you, I have made up my mind and with good recommendations from you guys and at my local field, I will get the UCD with a .46 ax engine. Thanks!

P.S I was thinking of selling the Sig Something Extra, Its like new. Just the body without any servo's or receiver. Email me here on RCunverse if anyones' interested, including the OS. 46 FX engine. It only has 2 and a 1/2 gallons through it, Like new.
