Hi <br /><br />After reading about Rook's Pawn III, using hitec 5990. After a few email exchange with Matt, I have decided to order the hitec 5990.<br /><br />It arrived yesterday.<br />Here are the test.<br />I compare it with the standard kondo KHR2 servo 788<br /><br />RCB3J, 7.2V 1.5A, custom software.<br /><br />Unmodified Hitec 5990 5 minutes<br /><br />Speed: 0.1367ms @60degree (kondo 788 was 0.1523ms)<br />Temperature: very cool (kondo 788 was warm)<br />Pan: 24Kg above that the 5590 start to struggle (kondo 788 9kg)<br />tilt: 2.5kg above that the 5990 start to struggle ( kondo 788 1kg)<br />Accurate: to 1 degree +/- <br /><br />Overall: For the price of $110, I was very impress with the hitec 5990.<br />Speed and torque was very good. The temperature was cool compare with the kondo and other standard servo. The only problem I have is the high pitch sound. But after awhile I get use to it.<br /><br />Modified version <span style="font-weight: bold">360</span> degree Hitec5990<br /><br />I did the same test as above, but I let it runs for 10 minutes straight.<br />(speed is randomly selected from the software min. to max interval)<br /><br />Without load: the temperature was a bit warm. 38C degree<br /><br />With Load (5kg): The temperature was getting warmer. 46C degree.<br /><br />Keep in mind that I was testing indoor with the A/C on.<br /><br /><br />I did the same test 360 degree with JR servo and MG995.<br />They burn out after 5 minutes with 5kg load.<br /><br /><br /><br />Summary:<br />Probably one of the best servo I have seen in the Market for the price of $110+tax. However, I notice that Hitec only give you one servo horn. For that price I think they should give a few more.<br />On the Hitec website, 5990 has a torque of 30kg.cm<br />But when I tested on a tilt, it was weaker than the Hitec 805BB which only has (24kg.cm). Nevertheless, if you want a good servo and have a lot of money I suggest getting the 5990, but if you want to load onto a tilt, then I suggest you getting the 805BB.<br /><br />Thank for reading<p>Statistics: Posted by <a href="http://forum.robosavvy.com/memberlist.php?mode=viewprofile&amp;u=331">AI-Bot</a> — Fri Jul 06, 2007 3:44 pm</p><hr />
