<P>What motor are you using? I am building one. I am planing to use 9411 on elevators (max ~20-25 degrees). 8411 on ailerons (max 15-20 degrees) and 8611 on rudder (max ~35-40) degrees. Using the Scorpion F3A motor. I think I should be fine with this se<FONT style="BACKGROUND-COLOR: #f5bfbf">t </FONT>up for IMAC. Any suggestions welcome. <BR><BR>Vicente "Vince" Bortone<BR><BR>----- Original Message -----<BR>From: "Dave" <DaveL322@comcast.net><BR>To: "General pattern discussion" <nsrca-discussion@lists.nsrca.org><BR>Sent: Monday, March 29, 2010 10:00:32 AM GMT -06:00 US/Canada Central<BR>Subject: Re: [NSRCA-discussion] MG Servos to use<BR><BR></P>

<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">I put a little bit of flight time on an EF 78” Extra electric 2 weekends ago (It has 8711 HVs running on unregulated 5 cell Nimh – so figure 400 oz/in and 0.15 sec – definitely overkill). My personal opinion is that 100 oz/in of digital torque is fine for elevator (2 servos), but more like 150 oz for ailerons (2 servos) and 200 oz for rudder, especially if you are going to have 3D throws.</SPAN></FONT></P>

The 8717s draw a lot of current, but have absolutely stunning performance – very stable roll trim, smooth response for pattern stuff, and very positive/crisp for snaps and 3D work (and yes, pricey at $140, but I think an example of getting more performance for more $$$).</SPAN></FONT></P>

<P class=MsoNormal><FONT face=Arial color=black size=2><SPAN style="FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: Arial">I need some MG Digital Servos to use on the 78" Xtra. These need to have at least 100 in-ozs of torque and I prefer at least 0.15 sec transits. I've looked at Airtronics and JR.....For cored servos prices are not too bad but for coreless, prices are too high. I prefer coreless. </SPAN></FONT></P></DIV>

I'd like reasonably priced (50-70$ as opposed to 120$), metal geared servos with torque and speed shown above. I started to look at Hitec but I understand these need some kind of programmer!? The need is 4 at about 100 in-ozs and 1 at about 170 in-ozs</SPAN></FONT></P></DIV>
