The NitroPro servos are AGFrc servos actually.
the 550tq NP is a A80BHSW servo

You can buy the USB adapter

And configure the NitroPro and AGFrc servos for SSR and Futaba.

Product page doesn't list any conditions, just says lifetime warranty

Please see posts earlier in this thread, yes the outer case is the same, but NitroPro servos have upgraded pots, fets, board, improved the fasteners to prevent servo motor pinion from coming off nor the pot sliding out of place, they have essentially fixed 3 out of 4 common problems with AGFrc servos

I picked up a SRT BH6027 after my DS1015 broke (well, pot came loose, I fixed it now but impulse-ordered a new servo at the track) and I'm not really impressed. I have a PowerHD R12 in one of my and was really impressed by it, incredibly fast just like the specs state, so I believed SRT's specs (same OEM after all) and ordered this one even though I could barely find any info on it otherwise. Quite glad I didn't pay extra for the full alu case version.
According to the specs the BH6027 should be a tiny bit faster than the DS1015 @6V (I still have one DS1015 for throttle, so the system's running on an unregulated 2s LiFe for now) and well, it's not. It feels lazy in comparison, it's still likely more than fast enough for a 8th scale steering servo for me considering the DS1015 felt a bit twitchy but the specs simply don't line up. Either the DS1015 specs are understated, or SRT's are overstated. I might spend some time later to test which is the case, but as it stands right now, even the JX CLS6322HV is years ahead of the BH6027 in terms of speed and not that far behind in terms of strength (the latter at least according to specs). One point for the SRT though, it's quiet when it's centered/not moving and definitely has very low power draw, my voltage barely drops when I do the "death wiggle" with it, while almost (the PowerHD R12 doesn't) all the coreless servos I have really suck up the juice when doing that.

NitroPro fixed nothing,AGF improved their own product as I here the latest AGF brand has the same improvements to them

Aaah ...another FB fanboi ...ok

I just purchased one of these because it was pretty freaking cheap and has some decent performance numbers. Have any of you had any experience with it? I know it's solid core, but I'll still give it a try.

I had one of this SPT in Tamiya M05 and it was ok.
Then I installed it in 4wd 1/10 buggy and it broke in 1 session, 15 min.
No miracle, performance in line with price.

Time for another race report from me.

The AGF A80BHSW servos in my nitro buggy and the Blue Bird BLS-30A in my ebuggy performed well all day during qualifying and racing. I'm not the best driver, and it was a new track layout, so there were a lot of crashes but all of the servos are holding up.

Has anyone tried the AGF A62BLS in 1:8 buggy or truggy for throttle?

I ran the A62BLS in my 1/10 Mini Truggy - PR Racing 401R-T and it stripped gears about once every 3-4 race days, I upgraded to the A65 and haven't stripped a servo gear since.

I would not recommend the A62 for any class... I would still occassionally strip gears in my 1/10 4WD Buggy as well, more info here:

Thanks, I was looking for a quick fix for my son, as the LHS had one, but if thats the case, gonna order another regular sanwa.

Thanks for the heads up Billdelong

Yesterday I drove my new car with a HDKJ DS3020
HDKJ DS3020 20kg metal gear, large angle, large torque, digital, waterproof steering gear, All meta - ????????

Bought a while ago 2 of them for just 33 euro a piece. 0.06sec, 20kg and brushless seemed a good deal. There is some latency when I connect it on my servo tester compared with a Align DS615 (Savox 1257 like servo) but hardly noticeable. But was doing ome practise laps on my crowded track with my 1/8 onroad and I could place the car fast and everywhere I wanted it.

So far I am pleased!

Thanks Roelof, we may give those a try too. for the price it seems fair.
