Hi T,
Check that the props are not pressed against the motor housings and spin freely.
Check that no hair is wrapped around the motor shafts. (requires the props be removed) From the Mini and Micro Multicopter section of the Quadrocopter and Tricopter Info Mega Link Index: --Micro prop removal made easy using wire cutting pliers 101

yup that's happened before but not this time.

I've caught this issue before too, I'll double check that when I pull the props.

J,

How would you describe your machine flew out of the box? What are you getting for charge/run times?

I'd love to see exactly where you are putting the glue. I'm not sure I'd get them straight. They all wiggle a bit in all directions.

I did about four or fove cycles on the new batts and still the same . They will charge to 4.15 but I'll get a minute of flight before the lights flash. Then I'll get about 30 sec more before it falls out of the air. Check the batt and usually have 3.95-4v at that time. Weird. Stock batt works fine and leds flash between 3.7 & 3.8v.

I purchased two cx75 replacement batteries from the LHS, just eyeing them they look to be different sizes and one has a much longer lead. One I'm lucky to get two minutes the other I can get about 3.5, stock lipo does about 2.5 minutes. Timed from takeoff to flashing lights.

Assume they are old stock or just poor quality.

I was going to suggest the same thing. Old stock and/or poor quality. Hopefully there will be replacements from Estes soon.

Ehhh.. I guess I'm out $10!

I'll just be patient and wait for "good" batteries to come out.

Just a thought, but in my case, the USB cable charger that came with mine would never get my original battery completely charged. I unplugged the battery and plugged it into the nice little charger that came with my Horizon/Eflite/Blade nano qx and got much better flight times. I also got 3 of the Ares CX75 bats and while 2 of the 3 had longer wires, they all work well on my proto. I am not using the canopy. It isn't that great looking and it doesn't fit well over the Ares 110mAh bats.

I wonder if recalibrating would help some of the folks who are finding the proto unstable. I do use the Hubsan X4 transmitter and have never put batteries into the included toy transmitter that was in the Estes Proto box.

I've been charging all proto batts on my tenergy and charging to 4.15-4.18 so they are all getting a full charge. I only use USB for charging while at work. I think I just got bunk batteries. I threw away packages and receipts so I'm out. Also what I thought was weird is the Ares packages were labeled 110mah butthe cells themselves said 100mah. Weird. They were a little larger than stock too.

Estes Proto X/Hubsan Nano Q4 accelerometer calibration and drift correction 101


Hi T,
Mine launched straight up and was stable out of the box. I will caveat that with the fact that I am used to flying the Hubsan X4. The Proto X is built by Hubsan. Hubsan recommends that the first thing you do before the first flight is to calibrate the accelerometers. You do this by:
1. Powering on the TX and then the Proto X to bind.
2. Making sure your trims are in the neutral position by hearing the loudest beep when you set them.
3. Then placing the Proto X on a flat surface, then pushing and holding the yaw stick down and to the right, and then doing a full side to side wiggle of the aileron stick until the Proto X's LEDs blink.

Note that with the tiny Proto X/ Hubsan Q4 Tx you have to find the corner with the yaw stick down and to the right where the motors do not run before you attempt to wiggle the aileron stick. This seems to be a bit tricky with the tiny Tx, but doable.

Put your trims in neutral and it should fly straight up with minimum stick movement to hover in place. If it significantly wants to go in one direction then re-do the accelerometer calibration, but this time put a few sheets of paper under the side it is drifting towards to counteract the drift. If the drift is still not cancelled, then add a few more sheets of paper to increase the offset angle and re-calibrate again. When you get this right you should never need more than a click of two of trim to get the model to a relatively drift-free hover. You will always need to be on the sticks to keep it in one position for more than a few seconds as only GPS fitted multicopters can do position hold, but it should not zoom off in one direction when well calibrated and with only a couple of clicks of trim. Note that you should never require more than 5 clicks of trim when using a multicopter flight controller. If you do then there is a bad prop, bad motor, motor/prop balance, motor tilt, or Center of Gravity(CoG) issue that requires attention.


The Proto X/Hubsan Q4 has no yaw trim on the tiny Tx so if you get some yaw drifting when you fly, then land with throttle full down for 3 seconds and the like the X4, the yaw trim will reset. Sometimes the yaw drifting can be caused by hair wrapped around the motor shafts, bent props (straighten bent tips and re-bend for correct blade tracking), or props pushed down to far that are rubbing on the top of the motor, so inspect for those issues too.

Flight times after about 10 flights
-Simple stable hover test:
-Charged using OEM USB charger about 25 minutes to 4.21v. (*lipos always allowed to cool down 15 minutes before a re-charge)
-Flight time to LED blinking is 3:15 seconds voltage reads 3.72
-Flight to no hover power 4:35 seconds voltage reads 3.57 initially and 3.65 after 1 minute rest.
Note: Flight to no hover power not is recommended for maximum lipo longevity. YMMV

--Gluing micro props on motor shafts 101
--Improving Hubsan X4 flight performance 101 (for other performance Tip ideas and the Hubsan X4 Tx Tips)

As others have noted using a larger OEM Hubsan Tx or one of the hobby grade Tx's that are hacked to use Deviation firmware or Midelic's Hubsan module will fly with even more precision.

Hope that helps.
Cheers,
Jim

Bad news guys. I just discovered a serious undocumented flaw with the 350QX. It is a little disgusting to be honest.

Apparently they are susceptible to mite infestation.

Hi Jim,

Mine flew straight up right out of the box as well, I've been flying quads for a few years as well starting with the Walkera UFO #8, Ladybird V1 & V2, Hoten-X and then the Blade 350 QX. I'm charging using my GoPro USB charger, takes about the same, 25 minutes. After at least 10 flights I'm getting a solid 5+ minutes of flight time even zipping around a bit. Sure seems to be some inconsistency in the original batteries...guess I got lucky.

Regards,
John

I have a Devo 10 with no hardware mods. Would I be able to control the Proto X with the latest Deviation version? Or would I need to mod it to add a Hubsan radio module or something like that?

Thanks
