I have just purchased a Great Planes Ultimate 160.. I am at a loss as to which engine to power it with? OS 160 ? Saito 220? Saito 180? DA 50 ? Fuji Imvac 43EI ? OR WHAT????? I have read and heard sooo much GOOD and BAD on each choice. If any of you have any of these Combos, please share your experience and suggestions as to what power plant is best. Your Help will be greatly appreciated!!! MANY THANKS, WOODIE
