Newbie to pattern here. Picked up a softcover by Dave Patrick and got interested in pattern. Picked up a Sequel and it is now my baby. Anyway, is the SAP too much for this plane? I also have an OS 1.6. Looks like either of these will be a snug fit. What do ya all think?<div>Thanks, Bob</div>
Ideally, you want about a 4 1/2" wide firewall minimum (5" preferred) to fit the soft mount. You might shoe-horn it in but it will be tough for a seasoned veteran of pattern builds. A nooby might find it impossible.
Powerwise, the 180 can always be throttled back, or don't bother with the pipe. The muffler will work fine, but then again, you still have the fit problem
I suggest you stay with something like an OS120 and the smaller soft mount
