| Skyediamonds1985 | Guillows Series 800 - Stearman PT-17 | Build | 03-Jul-15 19:45 |  | | Views : 527 | | Unique characteristics of the Continental R-670 are: intake and exhaust pipes are behind the cylinders with the main exhaust manifold hidden behind in the nose, the main electrical harness is wrapped around the main crank case behind the cylinders with the front spark plug wiring routed around the cylinders to go behind, the push rods are also behind the cylinders and each cylinder has additional cooling fins for the exhaust. Those were the details I wanted to highlight on the scratch radial. Finally, the engine had to be in 1/20th scale to the aircraft model itself. |
| Skyediamonds1985 | Guillows Series 800 - Stearman PT-17 | Build | 03-Jul-15 19:30 |  | | Views : 582 | | One of the more unique characteristics of this particular radial, is the main elect. harness is located behind the cylinders, with the front spark plug wiring being diverted around the cylinders to the back, the exhaust manifold is inside the nose, and each cylinder has extra cooling fins for their own respective exhaust outlets, and the push rods are behind the cylinders as well. |

| Skyediamonds1985 | Guillows Series 800 - Stearman PT-17 | Build | 03-Jul-15 19:19 |  | | Views : 527 | | First, need to carefully observe the Continental R-670s. If they used the Lycoming R-680s, then they're designated PT-13s. Go figure. |
| Skyediamonds1985 | Guillows Series 800 - Stearman PT-17 | Build | 03-Jul-15 19:01 |  | | Views : 611 | | Okay guys. This is my first model after almost 30 years of abstinence. With it, comes trials & tribulations with dashes of lessons learned (and errors to avoid). Keep in mind, all I have are: a pair of tweezers, needle nose pliers, scissors, an X-Acto knife and lots of imagination. Going to start off on how I (somehow) managed to scratch build the radial engine for the Guillow's PT-17. |
