Vendata I used that plate on mine so I really don,t know what would happen if I didn,t. I,m going to CYA and say don,t omit it. Ok now let me tell my story of how my day went with my Pred 2 first flight. I started out flying my trusty old Sonic to worm myself up. Thats where it all started. Made 10 laps then disaster struck. The wing folded. She spiraled in to the mud. Dam that made me mad. Got all the parts and set down for a wile .Fueled up the new Pred 2 and said what tha hell. Off she went . Trimmed her out . so far so good. Engine still to new to tell if she has it or not. but every lap she seen to get faster. So I landed her and headed back to the pits. My good friend Ray Just had to have my Nelson muffler. So I loaned it to him. He said Dub Jett is trying to put together a race class that will allow both 424 and 428 Q-500 to race together. It will be interesting to see how that turns out. Well so far I like the Pred 2.
