Thanks for your report on the "Score". But what happened to the pictures? No workee...
I love my DS .60bb...the SE, like yours. All the screws are 3mm x .5mm, and the lengths are same (8mm & 12mm) as a Tower .40 or Magnum XL .25 >.53, so those screw sets work perfectly. Mine came with slot head DS made screws, and they were terribly loose fit in the threads. The new socket heads fit the threaded holes very well, so it's not the taps they use. Mine has a through-flowing muffler, but it works pretty well, and isn't too heavy. Runs great, lots of umph, and starts easy. Choke, bump, flip, inverted on the wheels.
It likes a 12.5 x 6 APC very well, but I'll try Graupners and some wood props...13-5 or 6 Pro Zinger should work. I need something that will take some grass trimming, and isn't too spendy.
