Servo Review - Turnigy 1256TG

Having 2 chassis', that of course means having two of everything. All except my radio which can accept multiple receivers. I upgraded my main CS chassis to alloy and carbon fibre and I also upgraded to a sensored brushless setup so all the old stuff was donated to my "work in progress" D3 RWD. Problem is, I didn't have a servo...

I didn't want to spend loads of money, I have never really spent loads on my chassis unless I feel like treating myself. That being said, the overall cost is still quite high. So after looking around and asking a few friends about what they run, I decided to some of my own research.

With drift, we want a quick servo. It should at least be digital too for smooth operation, there are many other better options but for the purpose, a quick digital servo is all I need.

I have often used HobbyKing for a lot of the electronics that I've bought but I do have to be careful when choosing parts as they have international warehouses and I seen others get "stung" by customs. HobbyKing have a Servo Finder option on their website which is very helpful; you punch in some information regarding speed, torque, dimensions etc, and they compile a list of compatible servos.

There were a few options but after selecting UK warehouse, my options were whittled down to 6 and of those 6, I decided that this one fit the criteria.

This is the Turnigy 1256TG digital servo. It weighs 57g, has a torque rating of 8.5kg and a speed of 0.08 seconds. It's a tall servo unlike my Savox 1251MG but as it's sat on it's side with the working end pointing inwards, it makes no difference to me.

Took only 3 days to arrive which is great and I was greeted with a box, popped it open and this is what I found:

There was a selection of servo horns all made from plastic but no servo-saver, not that I need/use one. There was also a selection of screws, bushes and mounts, again, no need for these. The servo did have a long length of wire for those who need it but I didn't and I don't like cutting and shutting so I coiled it up. You can find a tutorial for it here.

After fitting it into my chassis and selecting the appropriate horn, I powered it up and was pleasantly surprised. I've only tried it on a stand so far but this thing is quick!

The next step is to try it out on my local track and see how it goes. It's worth noting that this servo will be used on my RWD chassis with a gyro along with a FlySky GT3B radio. The gyro accepts digital servos and will be interesting to see how it gets on as I have heard about servos overheating or even being overloaded due to incorrect matching. If the servo is as good as it seems, I will most likely test it on my CS chassis and may even decide to switch the servos over.

So there you have it, a quick review of a decent, reasonably priced servo should you be in the market for one. Again, there are better, higher quality servos but this is good enough for me.


Thanks for reading and don't forget, RC drifting is for fun so enjoy it!
