Having run the Phoenix 1600 fitted with the Floater Jet motor on large prop for a couple of flights, it was clear that things were not well. Although the motor would launch the glider OK, after a while I could hear the motor skipping. Checking the specs, its speed rating is 2150kv compared to 1050kv, more than twice as fast, which explains the difficulty it was experiencing trying to spin the big 10.5x6 prop.
I swapped it over to the 6x5 prop I had been using on the Floater Jet and found things to be a bit happier - still under-powered but at least the motor was running true. However the appearance was rather unlovely so, having noticed a tweeter housing I'd set aside thinking it might be useful for something, I set about crafting a cowling for the front-mounted motor.
Surprisingly, things went rather well, and I fitted the cowling on with tack adhesive for convenience. It now looks like a 60's power glider fitted with an old-fashioned nose-job. While looking less ugly, it also seems to make the glider fly more efficiently - not more thrust but the battery now holds up for longer.
I've ordered a replacement motor, having abandoned hope of Hobbyking quickly processing my warranty claim. That will arrive next week, giving the Phoenix the power it deserves...
I had floater jet and i believe a 6x4 sports prop would be a better match,,, I also believe if you installed a turnigy 650 watt 2836-3200kv you would have double the performance using a apc 6x4 sport prop using a 40c 2200 3s
