Very very nice indeed. I can see them being at home on a super class, but way way over kill on a 2.2 crawler. I personally run a HS-5955TG on my comp crawler with great sucess. I have to wonder how well the plastic rod ends would last with that much torque lol Although at $150.00CAN, it comes in very close to the price of a HS-7955TG.

i dont think it is the same one. if you look at the number on the servo it is different the last one is a "g" and the other is a "h"

i hope it is cheaper lol. i could use one too

It mentions 2 in the first post.

The HS-7950TG has been designed for the most demanding hobby applications including the largest aircraft and monster trucks. Featuring a titanic 403/486oz./in. of torque at 6.0/7.4 volts , while still maintaining a respectable 0.15 second transit time

So I am guessing the TG's are out but th TH's will be out in June.

Looking at the difference between the TG and the TH, the TG has a listed torque rating of 403@6v, but the TH has a listing at 6oz and 7.4v

Is the option to run at 7.4v really worth what = to be more then $50 price difference? I ask, because I am a guy who has been happy with a 645 servo.

Great Hobbies lists a lot of new products on their site (Losi Comp Crawler, AE SC10) you just have to watch their inventory status, the 7950TG is listed as new and not yet in stock.

If the servo will run fine at 7.4 volts, that means you can probably get by without an external bec so you will simplify your wiring - that is as long as you run 2S Lipo because your servo could get its power directly from the battery.
If you are running 3S, you would probably still want to run a bec or maybe a seperate battery just for the servo.

Well, you can't buy the one linked to at Great Hobbies for awhile yet, anyway. The purple circle means not in stock and new item not yet available or something.

Hitec's TG designation has always been saved for the 'Titanium Gear' models, so I think at the moment, there is just the one. TH might be a slightly different model or a spelling error...
