Pete's RotorWay/JetExec Helicopter Page!

| During a midlife crisis at the age of 43 I suddenly decided I needed to do something completely impractical, irrational and financially irresponsible in my life. I bought a build-it-yourself kit helicopter called the Exec 162F, shown above, from RotorWay International in Chandler, Arizona. The completed Exec 162F is a full-size, two seat, piston engine helicopter with a top speed of 115 mph and a flying range of 180 miles. It is 22' long nose-to-tail with a 25' rotor span, will take off and land at 7,000' elevation and has a 10,000' flight ceiling. It can carry 425 lbs pilot and passenger load for a total 1,500 lbs gross flying weight. The original factory engine is a 150hp 162 cu.in. 4 cylinder fuel injected oil cooled piston engine with Fully Automatic Dual Electronic Computer (FADEC) control. I am currently building it in my tool room/garage. I selected the RotorWay kit because 1) it was a relatively inexpensive way to get into helicopters; 2) I wanted to build and maintain the helicopter myself; 3) I thought it might be a good idea to be intimately familiar with the workings of every moving component strapped to my backside; and 4) at 6'6" tall, I wanted something I could customize to fit comfortably inside. I visited the factory, got a good look at the helicopter and took a test ride, decided it was doable and in July, 2000 I purchased the first two groups (first half) of the kit from RotorWay. I received the first half of the kit in September, which included the welded chrome-moly steel tubing frame, aluminum tail boom and stabilizer fins, all of the interior and exterior fiberglass, windscreen and doors, and the main rotor mast and controls. Hadn't even started assembly and I was flying high already.
Due to my height, I had to make several modifications (1.4Meg) to the steel frame and fiberglass interior of the helicopter to allow me to fit comfortably inside. By dropping the pilot seat and moving the directional control (foot) pedals forward I managed to gain 6" of additional head room and 6" more leg room. I also widened the pilot and passenger seat areas some to improve comfort there, and I widened and raised my instrument console too. |

While I was building my kit, several other RotorWay owners were beginning to replace their factory 162F piston engine with a military surplus jet turbine engine. A company called KISS Aviation in California began to produce a kit that would allow you to convert the Exec 162F to a JetExec. Their conversion kit and the jet turbine engine replaces all of the RotorWay engine, chain and belt drive systems with a very reliable turbine engine and solid direct-drive components.
In August 2003 I visited KISS Aviation and ordered the conversion kit, #38, with estimated delivery in 10 to 12 weeks! Update June 7, 2004... Last week I was able to visit KISS again and was fortunate enough to watch Dave start bolting my main drive components together. Soon after, he placed them in the crate and voila'; my first shipment of KISS Aviation parts arrived today! The workmanship is very nice. I am really looking forward to assembly. Update June 29, 2005... I finally received the last part from the kit, the #1 T/R drive shaft tube. Latest update Sept, 2006... I understand that KISS has done a fantastic job of catching up on orders. Kits are up in the 70's now and recent deliveries have been made in 7 weeks! Way to go, Dave! |

The T-62T-32 turbine engine was originally designed by Solar for use in an Army single seat helicopter. The project was scrapped after the engines were already in production, so the engines were installed instead in portable electric generator sets. These generator sets are still in use by the military today and routinely become available as surplus, usually for about $3,500. This is a very good price to pay for an $88,000 jet turbine engine! The engines can be inexpensively rebuilt to brand new condition and will run for thousands of hours with limited maintenance. In this picture, the tan rectangular case on the left is the reduction gear box. The air inlet section to the turbine is next to the gear box and the burner section and exhaust are on the right.
Here are a few more pictures of my turbine after it was rebuilt by Joe Bedo. |

| This is the day after I drug the helicopter out into our driveway and test ran the turbine for the very first time. All of the mechanical systems are complete except for the T/R drive shaft. The three oil coiling systems and the fuel system are complete (well, O.K., except for the plastic fuel collection bottle hanging beneath the turbine drain.) For those who are currently building, I did put together a few additional pages on the cooling oil systems and the fuel systems, with pictures, plumbing diagrams and a complete parts list.
