I flew my Integral with the Himax 6330 four flights today. Updating the firmware to version 3.20 and setting the ESC with the recomended values seemed to solve all the problems. Lots of power now, runs smooth and quiet. I'm happy again!

how thick the firewall for the motor should be? Will 6/32" aircraft grade plywood + one layer of carbon fiber cloth (4 oz) on each side be good enough? Sorry this is my first f3a motor. Thanks again.

The important thing about a suitable firewall is whether it will allow too much flex after it is installed. Since there are many variables, it is not a simple yes or no to any thickness firewall or the material you plan on using. If you have a narrower fuselage, the chances are, carbon fiber sandwiched 6/32 ply should work, but this also depends on the amount and placement of the ventilation holes on the firewall. A simple test you can do to check the flex of an installed firewall is first installing the motor and the prop, grip on to both ends of the prop, and try to move it from front to back with moderate amount of force, the firewall should stays firm without noticeable amount of flex. If it does, you can always add some gussets to improve the firmness.

Hope this helps.

I use 1/4" lite ply with 5.7oz carbon both sides. Plenty stiff enough IMO.

Your 3/16" (6/32 is 3/16"), regular ply with carbon will be likely far stiffer than needed and probably fairly heavy.

and make sure not to remove to much material in one area when making lightning holes. It could cause the firewall to flex. I'm not a structural engineer by any stretch, but I try to leave a '+' and 'X' of material not removed. At least pulls/pushes/KE flight, the motor is 'supported'... I think. Here's how I did it on the Valiant.

Another happy customer......

Since I'm waiting for the new Plettenberg EVO II for my Xigris, I have moved my old EVO from my Genesis to the Xigris as a temorary solution. While waiting an new Pletty, I decided to give the Himax a try in my Genesis. I received the motor a week ago. The weight of my motor is 625g with the prop adapter, wires shorted about 50 mm, and with 4 mm bullet connectors. No mounting hardware indluded.

Last night I had three flights on it. I used a JETI Spin 99 controller with 24 degrees timing, and a APC 20 x 13 prop. Batteries was Flightmax 5000. First impression is that it is very quiet - more quiet than my EVO. I had to lean more on the throttle than with my EVO, but that can be caused by the prop - I think a 20,5 x 14 will be more suited to this motor.

I did not bring any measuring devices, but the readings from my controller where max amps around 60, and max (in flight) RPM of 6200. I know that the Spin amp readings is way off, so I will hook up my Eagle Tree logger at a later time. After 8 min flights (P11) I put back around 3300 mAh in my packs.

All in all I'm very pleased with this motor - I will post some log data later.

Best regards - Paul

I have about 30 flights on my Himax 6330-F3A right now, with the last 8 at the Richmond BARCS contest this past weekend. Motor still running very well, no issues. It was windy on Saturday and the motor/prop combination handled the wind easily. At a 200 kv wind, I had some initial concerns about top end rpm but it handled the windy conditions just fine. I am running a 20.5x14 APC and typically put back about 31-3200 mah for a P-11 flight. On Saturday in the wind, I was putting back about 3300 mah for a P-11 flight flying big and fast.

Paul, the 20x13 prop is probably a little 'light' for this motor and you aren't taking advantage of it's torque. I am pulling about 64A on a 20.5x14 APC on a static test on the ground, a little less in the air.

where did you order the engine from Pål???
I had a cheap china engine in my Integral but its som unbalance in it , I tried to order a new one ...but its not the same engine anymore ..they change the size off it and it is to long and almost 50 gr heavier... Chinees......
did you bought it here in Norway???

Chris has the motors in stock at F3aunlimited.com for $250 US.
We are having great success running them with the new castle HV80 Ice ESC's.

Hi
I see that the Axi F3a is just a few $ more than the Himax ...what is the smartest choise here?????

mups53

My Feedback: (41)

Rune the AXI is a great value but the New Himax can swing a bigger prop is more efficient and is about 60 grams give or take a few lighter than the AXI F3a.
I have both and I'm happy. Mike

Paul_K

I would go with the Himax (just three flights on it though......).
It seems to have at least as much power as my AXI, and it weight is at least 50g less. The power comsuption also seems to be lower for the Himax.

I like the various bolt options. It was a drop in replacement for my Plettenberg.

I bought mine at an introductory price direct from Maxx Products.

Best regards - Paul

Rune/Paul.

I also got one from Maxx Products.
I initially purchased it for a little IMAC model, but I just "had" to test it in my Centro.
Worked very well with an APCE 21x14. Probably also fine with APCE 20.5x14, will try that later.

It changed the flying characteristic of the plane a bit though, revs went down from 6600 on the Cyclon (20x13) to about 6000 with the 21x14.
(But so did the current, and quite considerably.)
Plenty pull, but a bit lower top speed than I am used to. But I liked it, so I have ordered a second one. The Fed-Ex guy just phoned!

Rune

Ok.placed an order at Maxx Products, not wery expensive ...but 5 times price of the chinees engine!!! but it seems like that is no good ...heard some had luck with it but mine is not good , lots off power but unbalance...tried to balance it at work , but it was to smal for the machine

Flew mine last night with a APCE 21 x 14 prop I had lying around. Before I was a bit concerned of the amp draw, but the amps pulled seemed to increase only by 5 or so. The RPM dropped to 6000, which seems consistent with your readings, Magne.

I put back ca 3300 mAh in my packs after flying P11 + some extra maneuvers. The 21 x 14 worked very well for me. I could trottle back more than with the 20 x 13, which may explain that the total power consumption was more or less the same with the two props.

The 21 x 14 on my Genesis don't leave much ground clearence though......[8D]

Paul_K

Last night I had four flights with my Genesis & Himax, this time with the E-logger onboard.

Setup: Jeti Spin 99 ESC at 24 degrees timing, APCE 21 x 14 prop, Flightmax 5000 20c batteries.

Attached is the log for the last flight - the logs for the four flights where very consistent. Schedule flown is sort of P11 [8D] with some extra maneuvers.

Max amp draw is 71,6 A, Max RPM is 6330, Watts peak is 2594. Total used is 3674 mAh. I like this motor a lot

Paul,


Which Eagle Tree RPM sensor are you using and do you by chance have a picture of its setup?


Thanks a bunch,


Joe

Paul_K

The sensor I'm using is this: [link=http://www.eagletreesystems.com/accessories/7.htm]EagleTree RPM sensor[/link] - Brushless Motor RPM Sensor (RPM-KIT-BRS)

I don't have a picture of it's setup handy (at work).

[link=http://www.eagletreesystems.com/standalone/standalone.htm]Airspeed MicrosensorTM V3[/link] is interesting. In the logging mode, it can produce data helping pinpoint the maneuver(s) that are flown too fast or too slow.

The only problem would be to keep the pitot tube away from the propeller airstream.

Jason Arnold

Hi Paul,

I think many people have issues with getting correct numbers out of that sensor me included. This is why Joe is asking for details of how you have it set-up. Your results look plausable whereas results from my brushless RPM sensor are up in the 64,000 RPM region whis is way off. And yes, the SW has been set to the correct number of poles...

Cheers
Jason.

Hi Jason

I have connected my sensor using both wires. I stripped the wires about 1 cm and placed them inside the bullet connectors going to the motor.

When I setup the logger with the Data Recorder software from my computer, I have to tell it to reject RPM readings above 7000. This is done from the "Advanced -> Set Min Max Values" menu. If I don't do that, it produces readings in the 50-60 000 range when the ESC is braking the motor, and also when the ESC beeps at startup.

Also, make sure you have the latest firmware/software from EagleTree as they have been fixing some issues with the RPM readings lately.

Hope this helps.

Best regards - Paul

Jason Arnold

That does help Paul!

Thanks heaps mate!

I will give it another go on the wekend as I had previously given up on it...

Cheers
Jason.

This can be solved by placing the Pitot tube along LE in the middle section of the wing as described in the manual.
