In our Customers' evaluations

1) The finish of our engine is very attractive in appearance, at first, when unpacked from on delivered. 2) Some of them has reported to us after observing closely for a week that it is so nice and it really is a shame to run the engine actually by mounting on the air frame, it had better keep displaying forever. 3) The other has come back with emotion, calling us all the way by the phone to report on "quiet purr of the engine", "extremely less vibration" and "the better response" etc.after actually mounting on the air frame and starting our "NITTO's Rotary Engine", which are the characteristic with the rotary engine. 4) Most of our customers have been telling us that the rotary engine is so suitable for practical use like this, or the understanding for the rotary engine had better be changed. 5) From our customers for years, "NITTO's Rotary Engine" has been running with extremely less vibration. He could not totally find out any trouble on the air frame caused by the engine vibration, despite fixing NITTO's Wankel Rotary Engine Glow Fuel specification 20 c.c. directly to the stunt air frame after flying 190 times. According to his experiences, he was forced to see cracks on the air frame caused by the engine vibration after flying 60 times of 4 cycles engine Glow Fuel specificationDisplacement 20 c.c. so far. Many people touched by hand with the main wing during our Wankel Rotary Engine running and were so surprised because of no real vibration. 6) When you mount our "NITTO's NR-20EP" on the airplane, the powerful flight can be enjoyed, as our Wankel Rotary Engine can revolve the propeller [16" x 10"], made by APC, maximum 8,600 rpm (when nitromethane 15% is fueled).At the same time, our customers can also enjoy the comfortable flights, because the exhaust sound from the engine is always very mild due to rotary engine characteristic. 7) Some of our customers have been enjoying the helicopter, total equipped weight 15 kg,on the condition of Rotor Blade 790 mm (rotor blade diameter 1,800 mm) Gear Ratio 8.0 (88:11) by mounting our "NITTO's NR-20EH" Wankel Rotary Engine.(by nitromethane 15% fuel). In case of using for spraying of agricultural chemicals and aerial photography,sometime the payload is about 8.5 kg after deducting the air frame weight.(In case of using "NRG-20H" engine, about 10 kg max. as the total weight is recommendable.)(Originally, our engine is developed on the assumption to fly without loading any cargo (total weight abt. 6.5 kg). Therefore Nitto do not recommend to fly with the cargo(total weight 15 kg). 8) The surprisingly quiet hovering can be enjoyed when the silencer made by HATTORI is used (Nitto are recommending as optional). Our customers have been enjoying to hear the wind roar (brattle) of rotor blade which used not to be heard by the engine sound.Our customers have enjoyed, together with the beautiful hovering without the engine vibration, just like the real helicopter is flying.Nitto Mfg. Works have developed the engine with the serious desire of "Let's experience the beauty and significance of Wankel Rotary Engine together with customers as many as possible" and "Let's popularize Wankel Rotary Engine throughout the world" have been strongly supported by many customers.Nitto Mfg.
