Airtronics BEC question
 

Quick tech question:
The only Airtronics SSR compatible servo I can find is a 94915 SSR SRG (a high-voltage servo).
If using a RX 472 and a Super Vortex Zero ESC on SSL, am I only getting 6v to the servo, instead of 7.4 because of the BEC in the ESC if I don't use a RX battery pack?

The specs of the 94915 servo are so much better @ 7.4v, then they are @ 6v.

If I can't get the higher voltage to the servo, what is the point of paying such a high price for an SSR servo?

I welcome all input on this question

Yes it will only get 6 volts.

The response of SSR is much better than standard servos. Thats what you are paying for. That response time is good at either 6v or 7.2v. The speed and power of the servo will of course be lower at 6v but you are still getting the benefits of SSR. (as long as you've enabled FH3/FH4T and SSR modes on the radio which should be either the M11X, M12 or Exzes X or Z)

You could also consider an ESC that puts out 7.2v such as the Tekin RSX for example. Alternatively an external BEC or rx pack. In my opinion the servo is probably plenty good enough at 6v anyway.

Thank you for your thoughts. I guess that begs the obvious question, is SSR really any better then SHR? Can the average driver even notice?

Probably not. I know some above average drivers that question why they spent all the money on it also. But its airtronics and will last. LoL

What's interesting is Airtronics speed specs for this servo are for 40º, not the normal 60. So it begs the question, what's it speed? If we assume that 60 is 50% more than 40 and at 40 it's speed is .06 seconds. Does this mean it's .09 seconds? Which is not a very fast servo.

People talk all the time about latency and while latency is important, when you think about the difference between a 5ms radio and a 10ms radio. We're talking .005 seconds difference. That servo is 10-20 times slower.

I've seen a couple of the better drivers in our club upgraded to a better radio with lower latency. They say they "feel more connected to the car". But you'd think combining good driving skills with a "better" radio would show some measurable improvements, but they really haven't. They aren't consistently beating the good drivers with old radios.

But getting back to your original question. If you want to run the servo with high voltage, you should be able to find a wiring harness than uses the balance wires on your lipo to power the servo.

Or you could run your receiver and servo right off the main leads. Just disconnect the positive wire from the ESC to the servo.

Airtronics pricey
 

I have this servo.on the way. I admit I liked its desgin, as it is more beautiful than most servos and makes the futaba and hitec look like hideous industrial devices.

The ssr was mandatory since I can detect the slightest latency from years of obsessive video gaming. Ssr is more than just low latency and high bus speeds.. It's got other secret sauce.

Steel gears are heavier but for durability they are unmatched. I love titanium alloy's lighter weight but its only a 8-10 gram penalty in this case. So Sanwa spent time making the steel gears light.

0.06 transit time over 40 degrees is marketing, they are 0.09. Sec. Still it's a tradeoff I'm willing to make to try out ssr. I also have a hitec d940tw titanium coming and I'll text these back to back.

Anyone else have experience with this rare bird?

OP, how did yours turn out?
