Hi Everyone -

Decided to give the Gemfan Flash 6042x3 a spin on another motor, I know the 2212/6 2200 kv motor is not necessarily a quad motor, but I think it is the standard by which all other motors are compared.  I ran this motor for hundreds of flights using the MA 6x4x3, so I gave it a try with the Flash 6042x3 and found some very good numbers.

Tested with the Turnigy Plush 40A ESC with timing set to low on 3S.

50% throttle - 14.7A/182.6W producing 560 gr/19.8 oz of thrust;

100% throttle - 33.5A/386.7W producing 1080 gr/38.1 oz of thrust.

This is almost 200 gr more thrust than what I tested with the MA 6x4x3, so I will field test this for sure and see how it works out.  Anytime I see over 1000 gr of thrust with this motor on 3S, I am pretty pleased.🙂  After some more thought, I think the Flash 6042x3 might be just a bit too much prop for the Racerstar BR2406 2600 kv motor.

Cheers,

Scott

Hi Everyone -

Managed to get out and do a bit of field testing today, first up the ever popular and reliable 2212/6 2200 kv motor with the GF Flash 6042x3 prop on 3S.  Bit of a close call at about 2:12 of the video😉


I am pleasantly surprised by this setup, the more I flew it, I was impressed by the speed and performance.  Acceleration as you would expect not quite what it is with the 2 blade version of this prop, but I think a bit quieter and these props are not terribly expensive.  The motor certainly seemed to have plenty of "oomph" to spin this beefier 3 blade prop.🙂

Next up, the Racerstar BR2406S 2600 kv motor with the Master Airscrew 6x4x3 prop.  This is not quite as fast a combo, but quite efficient.  I would say that you could run this motor/prop combo with a 30A ESC without much problem, saving a little bit of weight.  With the right throttle management if your plane wasn't too heavy, you could squeeze 6-8 minutes of flight time out of a 2200 3S battery based on the amount of "juice" I saw left in my batteries after each flight.

Hi Everyone -

Out doing a bit if experimenting with high timing on the reliable Turnigy Plush 40A ESC on 3S with the very amp hungry GepRC GR2306 2750 kv motor and Gemfan Flash 6042x2 prop combo.  Previously, I had only tested this motor with the Plush ESC on low timing and with props that drew much less amps but also produced much less thrust.  I don't have exact thrust numbers, but from what I saw today, I would say they would be very close to what I have seen with the HobbyWing Platinum PRO 40A ESC that I usually run with this motor/prop combo.  

I did a quick 5 second spin with the wattmeter prior to the flight, saw 48.5A/553.9W.  Here is the video, another very close pass at about 2:39...#propwashinyourface ðŸ˜‰

I'm not sure I would chance running this ESC with this motor on 4S, unless maybe you were running a 5" 3 blade quad prop where the amps might stay down around 55 or so, although it would only be about a 200 gr increase in thrust over this prop on 3S.  With the 6x3 EMP prop which would give about 400 gr more thrust than the 6042 prop on 3S, I would estimate you would be drawing around 60A on 4S which based on the heat build up I saw today might actually cook the ESC😳

Hi Everyone -

Based on some questions I have had on my You Tube channel recently about ESC timing, I put together this video summarizing my experiences experimenting with it on the bench and at the field.  Sometimes it helps to change, sometimes not🙂

Hi Everyone -

I have been using the GepRC GR2306 2750 kv motor in my park jets for over a year now, it is my absolute favorite motor that I run on both 3 and 4S and has proven to be incredibly reliable and durable through over a year of some pretty rough treatment on my part😎  I shot this video summarizing my long term review of this motor.


Cheers,

Scott

Hi Everyone -

This video isn't exactly all about quad motors/ESCs/props/batteries, but rather a summary of my current favorite "Park Jet things" based on the questions I get asked the most through You Tube, e-mail, etc, I figured this thread was as good a place as any to put it.  


Cheers,

Scott

Hi Everyone -

After highly praising the GepRC motor a couple of posts ago, I got showing off at the field a couple days ago and found out where the amp limit might be on this motor, or at least the one that was in my plane🙄  Hopefully you can see the rather black windings on the stator in this picture, not a good thing!  It is still an outstanding motor, but like everything has it's limitations.
2019-07-06 09.16.35.jpg 
I had been flying around with the HQ 5.1x5.1x3 prop on 3S and decided to drop a 4S battery in the plane to show off in front of some other club members, forgetting that on the bench it had tested at 67A on the GepRC motor (senior moment😳).  So it went well for about a half dozen high speed passes and then on a full throttle climb out things went quiet really quickly!  Fortunately, I had some altitude and the RC Gods were on my side, so I was able to land the plane without incident, but the motor (at least the stator) is now toast😧

Based on what I have read, this motor is rated at 45A and I have pushed it to that I am sure numerous times, it draws about 60A on 4S with the 6x3 EMP prop on 4S, so if the rule of thumb is that the motor pulls about 25% less than that in the air, this would equal 45A, although the motors have come down hot with this setup when I have flown it numerous times, they still kept running strong.  However, if it pulled 67A with this HQ 5.1x5.1x3 prop, it was theoretically pulling 50.2A in the air...just a little too much obviously.  

Oh well, allowing my ego to write checks my abilities can't cash (to quote the movie Top Gun) is obviously not a good thing, I got lucky that the plane survived. Ego bruised, lesson learned and I will use the bell of the motor as a spare should I "cook" another in the future when I have another "senior moment".😉

Cheers,

Scott

Hi Everyone -

A couple of videos I just shot updating the reviews of a couple batteries that are new to me, as well as some less expensive batteries I am still using that are a couple years old.

Review update of the Tattu 2300 3S 45C and GNB 2200 3S 110C batteries after 27 flights each.  Links to the batteries are in the video description if you watch on You Tube.


Long term review of the ZOP Power 2200 3S 45C battery, I have over 100 flights each on the five (out of the 12 I purchased over a series of purchases a couple years ago, I assume that they might have come from a few different production runs).


Cheers,

Scott

Hi Everyone -

A couple more battery review videos, first a long term review of the Zippy Flightmax 2200 3S 40C which was my "go to" battery for about 4 years.  I still have six left that are still going strong.


This video discusses my initial impressions of a China Hobby Line 1500 4S 100C battery I just received in the mail today.


More updates will be coming on the China Hobby Line battery as I start using it at the field.😎

Cheers,

Scott
