The TJ100 fan system was designed by Aeronautical Engineer Bob Parks. Bob utilized the Neu 1515/1518 series of brushless motors in the TJ100 EDF propulsion system for maximum efficiency. The result of this combination produces a high velocity up to 230 mph (370 km/h) at 12 lbs. (5450g) of static thrust. No other fan on the market can produce this kind of performance and efficiency combo under 4200W.

The batteries supplying the power also play very import role of the power system. Once again, the TJ100 propulsion system is designed to utilize standard 22-25C rated cells to produce maximum power. Most other fan units are running over 110A or using a high number of cells to produce comparable power. The downside to this approach is at a high amp discharge rate causes voltage drop (Voltage depression). In order to sustain comparable power it requires the use of heavier and more expensive 30C cells. Another approach to combat voltage depression is to use a higher cell count of 14S-16S rated cells. Increasing the cell count however; costs more weight and of course, money. By the shear factor of the weight of these cells require more power to fly on the same speed as the light weight set up.

The TJ100 has the advantage of high power at a light weight over all other fan systems on the market. Watt per watt the TJ100 propulsion system is 20% more efficient than the competition. This translates to less cost and less weight to get the performance you need.

Another advantage the TJ100 propulsion system is the diameter of the fan. Our fans are only 100mm. Because of the small size of our fan, our propulsion system fits perfectly within the confines of scale jets with smaller intakes.
