NEW WREN Wren 160 and Wren 70! Now available are the new 34lb thrust Wren 160 and 15.5lb thrust Wren 70. The Wren 160 is a light weight and powerful engine that will most all of the large aircraft kits/ARFs currently on the market. The Wren 70 is a factory assembled only option for the MW-54 that comes from the factory producing over 15 lb thrust! |
The new Wren 160 is an engine that packs some serious thrust into a small light weight package! This engine is ideal for many of the large aircraft kits and ARFs currently available.

Perfect for JHI line of aircraft, the Wren MW-44 "Gold" engine is an upgraded version of the MW-44 7 lb. thrust turbine engine. Through optimization of the engine RPM and diffuser design, this engine now produces 10 lbs of thrust with a faster spool up! This is the smallest production turbine available in the world being basically the size of a soda can. The MW-44 "Gold" is the production version and is available only as a factory assembled item. FOD screen as shown below is available as an option. See engine pricing.
MW-44 "Gold" Specifications |
|
| Thrust: | 10 lbs (4.6 kg) |
| Full Throttle RPM: | 195,000 |
| Length (w/o onboard starter): | 5.31 in. (135 mm) |
| Diameter: | 2.95 in. (75 mm) |
| Weight: | 1 lb (468 g) |
Based on the MW-44 engine, the turbo-prop harnesses the power of the MW-44 turbine with a gear box, creating a powerful turbo-prop/heli engine in a light weight and compact package! These engines can be used for turbo-prop aircraft (straight gear box) or turbo-shaft helicopter (90 degree gear box) operations. The gearbox is driven pneumatically using the engine exhaust gases to drive a second "free turbine" as opposed to a direct planetary type gearbox.

| Power: | 4 HP (3kW) |
| Length: | --- |
| Diameter: | --- |
| Weight: | 3.5 lb (1600 g) |
Wren70/MW-54 Mk.IV Specifications |
|
Wren 70 Factory Assembled Engine |
15.5 lbs (7.14 kg) |
| MW-54 MkIV Kit Engine Thrust: |
14.5 lbs (6.6 kg) |
| Full Throttle RPM: | 160,000 |
| Length (with onboard starter): | 9.85 in. (250 mm) |
| Diameter: | 3.50 in. (89 mm) |
| Weight: | 2.18 lb (990 g) |
Recently entering into production is the much anticipated MW-54 SuperSport 18 lb thrust turbine. Packaged into the MW-54 size and weighing just over 2 lbs, this engine gives big performance at a fraction of the weight of other engines available in this thrust class. This has been achieved through optimizing engine efficiency and with a higher compression ratio. This sets new standards for performance and efficiency for such a small size turbine!
MW-54 Mk.III Specifications |
|
| Thrust: | 18 lbs (8.2 kg) |
| Full Throttle RPM: | 160,000 |
| Length (with onboard starter): | 9.85 in. (250 mm) |
| Diameter: | 3.50 in. (89 mm) |
| Weight: | 2.18 lb (990 g) |
Using the MW-54 engine with a gear box, this opens up a whole new line of possibilities! These engines can be used for turbo-prop aircraft (straight gear box) or turbo-shaft helicopter (90 degree gear box) operations. The gearbox is driven pneumatically using the engine exhaust gases as opposed to a planetary type gearbox. The turbo-prop utilizing a 28x10 propeller will generate over 50 lbs of thrust!
MW-54 Turbo-Prop/Shaft Specifications |
|
| Core Engine : | MW-54 |
| Power: | 8 HP (6 kW) |
| Length: | 14.5 in. (365 mm) |
| Diameter: | 14 in. (355 mm) |
| Weight: | 5 lb (2268 g) |
