It would stand to reason that logic would carry forward with servo gears as well. Not saying that larger pitch servo gear would be less efficient, but having a smaller pitch gear could increase the opportunity to offer a wider range of efficiencies, perhaps that might be why AGF servos seem to offer the widest range of torque/speed selection than most other brands on the market right now. To me that's a win/win every which way I see it :)

Great point except the AGF gears are actually cut into a larger pitch than the others and that makes them less precise. Way to strategically twist around what I said for yours sales point

There are 2 schools of thought, one could argue that a larger cut would be more durable and less likely to strip, I am experiencing this issue with my mini truggy right now which uses 48P gears and I'm working on a conversion to use 32P gears... no matter which way you go there will always be a trade off.... regardless I would recommend trying the A80 BHM, it's super smooth and way more precise than some $150+ servos I have owned! I would be willing to bet that AGF is the OEM for rebrands out there who are charging 2-3x as much.

yes I totally agree that the bigger the pitch the greater the durability with the trade off being precision. I would try the AGF it it would have the same Sanwa fastest response mode compatibility like my current servos of choice. That is a big priority for myself and why I am ok with paying more for a more premium servo and having factory support easily at my disposal

You're in luck because they do have an optional programmer for SSR:

I'm telling you, these AGF servos are legit :)

SSR is good but SXR mode is where it’s at, The difference is amazing with the pro performance on SXR vs the Sanwa SXR servo it has to be felt to truly be appreciated and they are plug and play no programming necessary

But there are probably no servos out there which support that...besides the one from SANWA:weird:

yes Pro Performance Rc does and they are better than the Sanwa version by far, I had the Sanwa’s and tried these and these are the best servos I ever had. All of my Sanwa’s are now sold

I've been running AGF servos for a while now, 6+ months with the A80BHM in my SCT410.3 and about 3+ months with the A62BLS in my mini truggy (PR Racing 401R-T).

Just this past week I stripped the servo gears in my mini truggy, and I knew exactly the moment it happened was when I quickly turned the wheel on a botched landing from trying to get the truck to level out. That said, the servo was only rated for 167oz-in of torque @6V, I will be swapping it with the A65BHL which is rated for 348oz-in @6V. The A65BHL is in between a shorty and standard servo which makes it a very interesting servo to try.

Anyway here's a closeup of the stripped gears on the A62BLS which ironically use the same replacement gear set as the A65BHL, so check back in another 3+ months to see if the A65BHL holds up!:

You should be able to get spare gear sets.

I stock a range of the gear sets, but not the A62BLS im afraid.

I have been ordering my gear sets here, I think it took about 6 weeks to get my first order:

running one in my Tekno MT410. Been in there all year, still works like new. Zero complaints.

One of the best cheap digital servos. I have four of them and they all work great!

SPT 4412LV - $12 shipped

I stayed away from Futaba, Savox and Ko Propo. I'm just now using Power HD and SPT in my kits. They all perform well as expected in their claim, cheap and reliable.

They are an interesting offer...sadly I ordered some 3 times and it never got delivered :sneaky:

So my recent gear set order from AGF just arrived today, I placed the order on the 16th so that's a 2 week delivery which is pretty impressive. Only odd thing is this time they didn't include any product labels, just clear zip lock bags with the gear sets in each bag. I had to staple my own hand written label on them so I didn't lose track, I also have gear sets for the standard servos too and don't want them to get mixed up.

They also included this freebie in my order and I have no idea what this is, anyone else seen what this is used for? I checked their website and couldn't find any product pages with this anywhere:

If I didn't know any better I would guess that it's a key chain, but it kinda looks like there might be LED's on it maybe?
