Here's a short "review" of the budget-priced EXI D227F digital, coreless HS servo. These can be purchased from hobbypartz.com for $14-$16. Depending on which of the 2 available servos you choose. (D227F or D226F) I went for the HS version. Took about 6 days to arrive in SE Tx from Ca. Not bad, especially for FREE shipping. One of the reviews stated that the O-ring EXI used for the output gear is the wrong size. Which can cause these servos to prematurely fail. Upon dis-assembly I noticed my servo didn't have said O-ring. Took a look at the gears and bearings. There is one plastic gear, so not completely MG. Better to have a weak point than burn up a servo. It comes pre-lubed, so no need to do anything. So back together it went. I am running this servo in my LCG/Pro-Trac 2WD Slash. I run a MM esc paired with a Tacon 3930Kv motor. Controlled by a Spektrum 3.0 Tx/Rx. I ran both a 2S 5K and a 3S 5K with this servo installed. Hobby Partz' spec chart claims that @ 6V this servo puts out 111oz./in. @ .09 sec. Not too shabby. A little less torque than the stock 2075, but more than makes up for that with its speed! Lighning quick steering response! Had to turn down my ST expo to get her under control. :P I have only had this servo for a couple of days. So can't really speak for its longevity or durability. It centers itself better than my other $40 servo. Didn't take any temps of it after my runs. The only running I have done so far is strictly bashing. Pavement, gravel, grass. No track time yet. Seems to have great holding power. As of today, (12/17/2010), I can confidently recommend this great priced servo for anyone looking to replace their demolished stocker. Or someone who would rather spend $15 on a new servo rather than on a new set of gears. (Me being the latter) Here are a few pics so y'all can see what it's made of.
There you go guys. Hope this helps newcomers and vets alike. Now get those batts peaked and go outside and BASH! Take it easy y'all.
