This week the Raptor 140 completed a 30km (18.6mi) fully autonomous flight! It only used 58% of it’s 8.8Ah batteries, giving it a potential ability to cover 51.2km (31.8mi) on a single charge, the whole time flying at 75kph (47mph) for 40+ minutes! Impressive…
Some additional metrics to consider: is average amp draw was 12.8amps, or 21% of the 60amp esc, also it had a 5.8km/Ah (3.6mi/Ah) efficiency, meaning that if I added an additional amp hour of battery life, it could cover an additional 5.8km or 3.6mi. The original Raptor did an average of 5.5km/Ah.
Next week I’ll start pushing the speed limit, seeing how fast and far the 140 can go. My end goal is to be able to cruise at 100kph (62mph) and still have a reasonable efficiency.
Also, I’ve been asked by dozens of people if I’d make a 140 for them, so I will! Starting in November I’ll start selling Raptor 140 kits on my website: MyGeekShow.com. I plan on shipping worldwide and will have kits available starting at $89.99.
