Based on a track record of over 15 years of the earlier Dynamic being used as a glider towplane, and it is around 300 are currently being used around the world for this service, the new Super Dynamic WT9.15 represents a quantum advance on what was already one of the most cost-effective towing aircraft around.
The first example in the UK has two tow hooks, a standard Tost retracting system and a back-up standard Tost hook together; there is a rear mounted camera with an easy to view cockpit display. The double hook system and camera is shown on the photograph below, .
The cost of maintenance is very low as Dynamic aircraft come under the auspices of the BMAA (British Microlight Aircraft Association) maintenance system and, with much owner maintenance being permitted, the operating costs are significantly lower than for the more traditional glider towing aircraft operating under Part 21 regulations.
But can a microlight aircraft really operate in challenging wind conditions? This can be a major feature of operations at the well-known “wave” sites? The answer is that the Dynamic has proven ability to do so and in New Zealand the Dynamics are often the last machines to be put away in the hangar when the wind really blows. With a crosswind limit of over 20 kts the Dynamic is clearly a versatile aeroplane.
The new Super Dynamic ushers in an era of affordable aerotowing even under the most challenging conditions.
With the Pawnee and Super Cubs nearing retirement, the hunt is on for the next tow plane. Not least with the associations in Norway and Sweden who have bought Eurofox with 141 hp Rotax. But the Dynamic WT-9 also comes with the same powerful engine. You’re the one? NORDIC GLIDING has tested it against the on paper more powerful 180 hp Super Cub from Ålleberg. The result is impressive.
- The article is about a test flight of the Dynamic WT9 15 GTI, a low-wing nosewheel aircraft with a 141 hp Rotax 915 turbo engine, designed for both glider towing and travel flying.
- The test was conducted by Nordic Gliding, a magazine for glider pilots in Scandinavia, in collaboration with Falbygdens FK, a glider club in Sweden, and Börje Ragnarsson, the owner of the Dynamic.
- The test compared the performance of the Dynamic with a Eurofox, another glider tow plane with the same engine, and a Super Cub, a classic high-wing tailwheel aircraft with a 180 hp engine.
- The test results showed that the Dynamic had superior acceleration, climb rate, and stability than the other two planes, especially in strong wind and turbulence. The Dynamic also had a modern and elegant design, with features such as a retractable tow hook, a rescue parachute, an autopilot, and a glass cockpit.
- The article concluded that the Dynamic was a fantastic machine, not only for glider towing, but also for travel flying, with a cruise speed of about 130 kt and a low fuel consumption. The only drawback was the high price, which might be a barrier for some glider clubs.
