Hacker A60-**S / F3A Compatibility

[toyplanez]

So far, unofficial testing shows outrunner motors like the Axi 5330/F3A can haul a draggy 11lb pattern plane vertical for as far as the eye can see, no problem. Most are running 10s TP 5300's (or smaller) and some flavor APC-e prop, 20-22" diameter, 10-13" of pitch. This results in WOT amperage pull of ~80A (w/ a 22x12 APCe) but after some practice and throttle management, a Masters sequence can be flown at less than 70A and 3500mAh (depending on winds, etc...).

The main specs for the Axi are:
RPM/V: 235
Weight: 652g (23oz) (1.44lb)

Now, the Hacker A60-20S (very similar):
RPM/V: 235
Weight: 595g (21oz) (1.31lb)

Key points: First, Hacker recommends a much smaller prop (19x10) with this motor as opposed to the 22x12 recommended by Axi. However, Hacker has lower KV motors such as their A60-22S (215 Kv) and A60-24S (200 Kv.) Second, Hackers are only rated to 50A "burst" where the Axi is rated at 72A "burst."

The question: Considering the similarities between the two motors, but realizing the Hacker A60-xxS series are rated to less Watts, can the A60-20S motor handle the power required to fly a “heavy” (11lb) pattern plane in Masters? How about FAI P07 or F07?

Thanks for reading...

EVERY hacker I have EVER had (and that is a bunch) are SERIOUSLY under rated. You can bet your bippie it wil stand toe to toe with a AXI. I would be shocked it it can't. All other Hackers will match or outperform AXI's and I own them too.

Call Hacker Brushless and talk to Sean. I can promise you Quique and or Jason Shulman has had one in a pattern ship for a while now and Hacker has feedback to give.

Dear Hacker Reps:

As Futurase suggests, are there any results or data coming from your A60-**S sponsored testers that you might share?

Thanks,

Send a PM to Jason Shulman as he does a lot of testing for Hacker and he is on RC Groups here (JAS) and is a very nice and down to earth guy.

If I wanted to know about Hacker and Pattern is the same sentence I would ask him.

The A60-S series motors should offer the competition pattern pilot a nice alternative to the Hacker C50 Competition (geared) system. As the pattern season has just begun, it will take a month or two for the final set-ups (kv, battery, prop) to be determined.

We believe the A60-20S using APCE 20-22" props and TP 5300mah batteries will provide excellent power for the 2M competition pattern pilot.

Thank you much for your reply, Kyna. I look forward to seeing data and these motors in action.

Thanks,

OK.. about 5 or 6 flights....

running TP 5300 Pro-Lites...

I put a quickie vid together with no music so you can hear the sound
of the prop/motor... Mostly prop... APC 22 x 10... NOT the HACKER
suggested prop.....

Hi again... wondering if any setups have been finalized yet?

I'm especially interested in an A60-22S setup and any associated data (prop, battery, amperage with wide open throttle on the ground, rpm, etc...)

Thanks!

Toy, there are two good places to ask where a lot of pattern pilots will read them.

1. RCuniverse's pattern and electric pattern forums
2. NSRCA.org's email discussion list
