Hobbyking Phantom FPV

by reddog » Sun Mar 16, 2014 9:45 pm

I ordered this airframe - http://hobbyking.com/hobbyking/store/__ ... _PNF_.html

The reason I ordered the plug and fly is because it was in stock locally. There are other airframe choices but I chose this plane because it has a good amount of fuselage space and the wing area is good for the weight of equipment I need for flying.

The PNF comes with motor, ESC, servos whereas the kit doesn't.

1. The ESC is crap, its got a linear BEC and its under rated. I used an external BEC on my first flights to see if I could use it and it couldn't cope.
2. The servos are OK (50Hz Max and even then they behave like the update rate is a little high)
3. The motor is pretty good.
4. Propellers are crap.

If the Kit (without the above extras) was available locally I would get it because I have a bunch of the above stuff.

Things I changed:

1. I switched the ESC to a 60amp version and used the BEC for power. This worked very well but could probably go down to 50amp.
2. I used a 4s 5000mah battery. 20 minutes flight time, approx 2200mah used.
3. Switched prop to 10x5
4. Moved the camera to the nose because it faces down way too much in the stock spot. Left the old camera hole open to maximize cooling.
5. Installed MinimOSD.
6. Used 400mw 1.3Ghz video transmitter.
7. EzUHF for manual control (stuck to top of canopy)
8. Quanton for flight control.

Conclusion

Plane flies pretty well for a $100 plane. Because it is a flat bottom wing it is much more susceptible to turbulence.

Built it in two nights after work.

Great cheap airframe for testing or getting into flying wings. Its the best one I have found so far for the price.

I can do that, I don't usually keep them, I mostly use them for making sure things look good in the air and nothing funny is happening during flight.

What could be the maximum flighttime? 40min with this battery?

I will test this further and get back to you ASAP. Flight times are definitely influenced by the flight mode. Manual mode eats the most power, Rate is more frugal and Attitude is by far the most frugal.

What do you think about this http://www.hobbyking.com/hobbyking/stor ... _KIT_.html compared to the Phantom FPV?

I read some of the Reviews and they said it wasn't good for FPV as the wings were too short and the airframe was draggy, so it was quite inefficient.

I am pretty sure you could get 40 minutes at cruise if you had the airframe setup properly. Mine isn't setup properly and I get close to 40 minutes on a good battery.

There is a guy on fpvlab claiming 2 hours 50 minute flight time with this plane. Of course he's burning close to 20ah of battery.
