ELECTRIC vs GLOW ENGINES POWER

Keep a look to this info :

One of the biggest confusions for most people selecting an electric motor is, “What is a watt?” The glow guys are used to horsepower and electric power systems are measured in watts.

(1 hp = 746 watts or about 750 watts)

Don't go by the max rating for HP that engine manufacturers publish. That is a MAX figure and very seldom is an engine for sport use operated at that figure. The h.p. drops off quite a bit when the RPM is not at the rated figure which is usually around 16,000 RPM’s or greater.

Glow Engines vs. Electric Motors

1. ♠ .20-size glow engine / 300w electric motor
2. ♠ (OS Max 0.20 engine develops 0.4 hp = 300w electric motor (AXI 2820) )
3. ♠ .35-size glow engine / 500w electric motor
4. ♠ (Fox 0.35 stunt engine develops 0.7 hp = 522w electric motor)(AXI 2826)
5. ♠ .40-size glow engine develops 1.0 hp = 750w electric motor (AXI 2826 or 4120)
6. ♠ .60-size glow engine develops 1.3 hp = 975w electric motor (AXI 4120 or 4130)
7. ♠ .90-size glow engine develops 1.6 hp = 1200w electric motor (AXI 5320 or 4130)
8. ♠ 1.20-size glow engine develops 3.0 hp = 2250w electric motor (AXI 5330)
9. ♠ DA-50 develops 5.0 hp = 3750w electric motor (AXI 5330)
10. ♠ DA-100 develops 9.8 hp = 7311w electric motor (Double AXI 5330)
