Glad to hear others are putting the DLE 30 in this plane. I have the 30 in a BH Ryan 120 right now,but it is eventually headed for the SS. I'm happy to hear that the distance from the firewall to prop, can be extended for muffler clearance without hurting performance. Trying hard to resist the urge to pull the trigger on the GP Waco. So many kits, too little time.
