I agree with you Vampire, course I am one of those guys flying a Funtana .90 with a Saito 1.80 in it! If you stretch the envelope, you build accordingly. If you break your airplane 'cause you didn't follow the recommendations, or didn't build it to accommidate the equipment you wished to use, don't whine about parts falling off of it in flight. I dunno how many Funtana .90s have went in because the pilot/builder didn't equip/inspect the plane properly before it was flown. I haven't gotten to the linkages yet but when I do I will be looking at the hardware and replacing any that does not meet MY standards, which are quite high. By the way, did you install a pump on your 1.60? (forgive me if I asked this already, most of the people I know who fly this powerplant use a pump on it. Me, being new to the big two stroke idea, don't have a clue)
