I havea currently retired Sequel Nomex.I can check on the fit for the SAP 180 but the fuse / cowl up front is way smaller than the Focus II. The firewall if not already installed couldpossibly bemoved back. Mineflew with a YS 120 SC. Even flew it somewith the TT 1.20 RE. The balance on the sequal like other well designed modelsiscritical to how it reacts to control inputs. When balanced properly, I have no mixes period. Pretty neet to fly hugh flat circles with rudder only and not have totouch a thing unless you turn too hard. Knife edge corner to corner and never touch anything but rudder unless you want. The thing almost corrects for wind tracking automatically if you pick the right speed. Notice I said speed and not velocity.A scalar and vector, respectively.- MTK understands. Makes me want to resurrect it the plane. Just needs TLC on the engine and covering. YS for me = Pain. Lots of power when working and usually didn't have trouble but when its off its off. Noin between......Thats why I triedthe OS 1.60 and now moving to the SAP 1.80. Just need time to finish my Focus with SAP. Missed a whole season. Not really...Its Florida. Cooler weather is coming soon to a flying field near you. Maybe more importantly is lower relative humidity.

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
