This afternoon was gorgeous and sunny, slightly warm with a gentle breeze from the south west, perfect for letting the recently-refurbished Radjet loose with its boisterous battery pack, the 1800 4S 40C borrowed from the Stinger.
As mentioned previously, I'd had several concerns relating it being too heavy with the oversize battery or simply bursting into flames due to the ESC being overworked. Fortunately, neither happened, with the Radjet taking to the skies without incident and flying well.
I did a few circuits before bringing it down, needing to make a few adjustment to the elevator settings after the servo change, and also to dial in a little more expo with the new servos having a bit more travel than before. Having sorted out the details, I threw the Radjet up again to give it another run.
The battery, significantly larger than the recommended 1300 and substantially larger than the 850 I'd been using, is rather oversized for the power system and changes the characteristics of the Radjet into something of a grand tourer. I think a 1300 4S battery is probably the ticket, providing enough current and flight-time without carrying any excess.
So, while this exercise answered one nagging question, it also raised another; considering it can comfortably carry the 1800, what if you uprated the motor and the ESC...
