Aveox F10 (36/15/1) and F10CS (36/24/1) vs. Hacker B50 6s on 10 cells

How does the Aveox F10 (36/15/1 w/ 3.7:1 GB) or the F10CS (36/24/1 w/ 3.7:1 GB) compare to the Hacker B50 6s (w/ 6.7:1 GB) on 10 cell in F5F competitions?

Regarding the Aveox motors without the integrated IMS 3.7:1 gearbox, what is required to install a 6.7:1 Maxon gearbox? Does it bolt straight to the motor or is a special adapter plate required. Also, as the drive shaft on the Aveox is 5mm, does Maxon have a pinion for this diameter shaft?

Thanks

You can't put 5mm shaft to any of Maxon boxes AFAIK. 3.2mm shaft maybe fits 5.2:1 maxon. Reason is that 6.7:1 has pinion milled directly to the shaft. When you compare two quality motors it's good to look weight and kv. if those match it's up to personal preference which one to choose.

I looked at this before Russ, the Aveox motors suffer from low KV, and the need for a lot of cells to get the most from them, and the lack taller gearing in their gear boxes. I decided that by the time I buy the motor and the hassle of doing the gearboxes its just better to get the hacker/plett setups. The other option is to go with the F series of aveox.

What aveox needs is a 27/39/.5 and a 5.2/6.7 to one gearbox....

Jay, how about the Aveox F10CS? This appears to be the 36/24/1 with an integrated 3.7:1 IMS gearbox. Again, attempting to use the B50 6s as the benchmark on 10 cells.

You would have to ask Efren about this. But if his Victor is any indication of how fast the f10 makes a plane go the NIKE 2 on the b50 6s was faster.

The F10 and F10C are not the same motor. I have all three the F10, F10C, and and Hacker B50 6S. I use both the F10C and the B50 6S with 10 cell and a 16*16, the F10C spins the 16*16 faster than the B50 6S. The F10C is a 36/24/1 with a 3.7 gb, the F10 on the other hand is a 36/15/1.5 with a 3.7 gb. In theory the 36/15/1 with a 6.7 gb also makes an interesting 10 cell combination at a really good price!, but I don't have one of those yet.

Tell me more!! So the F10CS out turns the Hacker B50 6s on 10 cells on the RFM 16x16. Any chance you can tach the difference or have a current draw? I like the Aveox 27/26/1.5 and would like to stick w/ Aveox on the larger sizes. It is just that there does not seem to be many out there.

Jay, Efren was using the Aveox F12S which is the 36/24/1.5 (Kv 2580, Io 4.30, Rm 0.010, 120 amp peak). Prop was the RFM 15x15.

The F10CS uses the hotter 36/24/1 (Kv 3724, Io 5.40, Rm 0.005, 140 amp peak)

Both are permantly mated to the same german 3.7:1 gearbox.

Ok, that explains the speed difference. I wish you guys could have seen that nike fly....

I used a tach to measure RPM, but I neither recorded the numbers nor measured current. All I have is an Astro meter not a clamp meter and at this power levels I don't want to risk it. IMHO, if your plane can handle the larger, then at $209 the 36/15/1, 3.7 or the 36/241, 6.7 is the way to go. The 27/26 series motor are fine for the smaller frames like the Smart or Banana. What plane do you have in mind?

The 3615/1 with a 5.2:1 GB was reviewed by Steve Neu in the March Quiet flyer magazine. The motor does not become alive until you get above 80 amps and looks like it can handle about 1000 watts.

Repeating second hand information (from Dave Sieger), this motor is being used very successfully in European F5F competitions with 6.7:1 GB and 16x16 prop which has had the tip trimmed slightly.

I've got one of these motors with a 6.7:1 GB coming in to try out. We'll see...

Hopefully when Dave gets a chance from his traveling and flying with the San Diego group this weekend, he can comment.

From the labels:
Prop. RPM ~ KV / gb ratio

36/24/1: 3724/3.7 = 1006 RPM
B50 6s: 6150/6.7 = 918 RPM
However, the best way to compare is to measure RPM and current...[IMG]http://[/IMG]

Aveox F10CS

Hello:
The F10CS will be installed in our new Zoom F5B, for some serious testing..
We have heard very good reports on this motor. We can also have the factory make up different gear combinations.

Happy Landings!
Bob

Sure it is possible--you need the right pinion gear--I have done it. A turned down shaft from 5mm to 3mm and the stock IMS pinion fits just fine. FYI--all the gear boxes you are calling Maxon are in fact made from IMS parts.

Steve, do the Maxon 6.7:1 gearboxes that come with the Hacker B50 have needle bearings for the planetary gears?

I believe the planetary gears on the IMS 3.7:1 gearboxes that are mated to the F10CS motors do not have bearings.

Is this correct? Any thoughts? Pro / con?
