In the UK I can only find 13x4 not 12x4 T-Motor props. Anyone know where I can get the 12in or has anyone tried out the 13in ones.

I have a NEX-7 and the SELP1650. I have looked at the possibility of using a servo and wheel to move the zoom button but the movement is so small I never got it to work. The other alternative may be to open the lens up and capture the contacts but have resisted, bearing in the mind the cost of...

I had looked at those props a while ago but i have 2 spare 11x47 CF sets and 2 APC sets in my spares box. However, if the flight time is improved I may give a set a try. They certainly look slick and being T-Motor suspect they are. Also with the extra inch of prop with the slightly lowered pitch...

Putting the GPS puck under the cover is possible: DJI do it with the phantom. However, it gets very crowded under there and it is best placed as far as possible from other electrics. The Xaercraft motors are T-Motor so are well balanced out of the box - I have not had to balance them. I do...

Rob is a nice guy and I suspect there are only two of them working there but are always helpful... although they won't give you a phone number.

Note that I started this thead moons ago. My spec is almost unchanged from my original post.http://www.multirotorforums.com/showthread.php?12285-XAircraft-X650-Pro-Owners However I would like more flight time and redundancy offered by an octi. Also with the weight of my NEX-7, I would like...

I don't think you will be disappointed with the pro. It had a proven design and mine has done a total of 71 hours flight time now. All standard Xaercraft motors esc frame and Wookom I use Arora 9 Tx AeroCraft gimbals and 8000MAH lipos. Djibouti OSD and 5.8 downlink. Lastly CF props. I changed...

Sorry to hear you lost your bird. As for upgrading a 4V I know there are kits out there. The plastic motor mounts may not be up to the power of larger motors. Certainly the ESCs won't be. Also the 4V can run on 3S lipos but the bigger motors, ESCs and props are all balanced for the craft. I...

Only make one change at a time. That way you know what makes a difference to the flight. Also don't fly in higher winds until you are happy with the machine.

I would like to point out that the x650 V4 is a world apart from the x650 Pro and although they look similar they are two different machines. Here it is lays out differences quite simply:- http://xaircraftamerica.com/blogs/news/8406539-difference-between-x650-v4-and-pro

4s is the minimum and recommended, but if you were to use a 5s or 6d you would need to consider smaller props or slower motors.

If that is a x650 Pro you should be running with 4s or higher. The X650 Pro run with 4x 30A ESCs and 4x 3110 800Kv T-Motor motors and swing 1147 and up props. The current draw is too much for a 3s. What you have to consider is that with the 800kv motor the props will be running at over 11000...

The motor bearings are relatively cheap and replaceable:- I don't know where you would buy the original bearings though.

I think that all y3 and y6 configurations are better suited for wind. They can certainly fly faster which makes them more suitable to flying in winds. Also the heavier machines will inherently be more stable in heavy winds due to greater inertia needed to knock them off course compared to...

I haven't got my BNUC-s yet and am working on my ops manual to get it. However, have flown IC helis since the mid 1980s so can confirm, to my own cost, that wind can be a killer for small machines. Although variable pitch machines are more adaptive and are not constantly speeding up and...

My quad can fly at around 35-40 mph in manual mode or about 30-35mph in GPS mode - that is air speed not ground speed. You would then expect winds of upto 25-30mph would be OK but the take-off means that the second you lift off the machine is going from 0 to 25-30mph in less than 1/4 second...

Having read up on the manuals for both the Tarrot and the GAUI the voltages are different. Like me you will have to run 2 UBECs:- 1. Tarrot will need a 7.2v or 9v unit http://www.hobbyking.com/hobbyking/store/__18786__9V_4_5A_UBEC_2_5S_Lipoly_6_23v_.html or...

If you want 7.2V Try something like this - http://www.hobbyking.com/hobbyking/store/__17160__7_2V_2_5A_UBEC_2_5S_Lipoly_6_23v_.html If you want 9v try something like this - http://www.hobbyking.com/hobbyking/store/__18786__9V_4_5A_UBEC_2_5S_Lipoly_6_23v_.html They are as cheap as chips and have...

That is exactly right it plugs into your balance lead and cycles through each cell and total voltage. You set the desired voltage per cell and when any cell drops to that voltage it goes off with a piercing squeal audible for at least 500 feet. I use this one...

The Martinez board can be set up to run on any voltage you want my altering the settings. However, the reason for the voltage guidance by Tarrot may be more to do with the brushless motors. The higher the voltage the faster they will move and compensate so by limiting the voltage to a range of...
