hmg9194 Posted May 4, 2011 Report Share Posted May 4, 2011 That's good news. I had him replace the piston head with a Prommy POM one. I will have a shooting video on Friday. Hopefully the AWS Pulse functions will work, as I heard they didn't work right in the masada from somewhere. (IE the 3 round burst and such) Quote Link to post Share on other sites

Works great and really quieted the gun down. Â I have the AWS Sentry. The 3-round problems I originally saw were a function of the crappy soldering job and from what I heard from others, the micro switch bouncing. It's not necessarily the MOSFET. You have the Pulse though, so it's going to know exactly the single fire rotations you get with that little switch device in the gearbox. A team-mate is putting one on his KWA battle rifle.

ericfine50 Posted May 4, 2011 Report Share Posted May 4, 2011 (edited) I just put a Systema M120 spring in mine and the motor was having issues pulling it. Thinking up upgrading the motor. Anyone see the new G and P Satan or the SHS ones? Edited May 4, 2011 by ericfine50 Quote Link to post Share on other sites
hmg9194 Posted May 4, 2011 Report Share Posted May 4, 2011 Get an SHS Short Ultra Torque motor, no need for the satan (shs is better, plus the satan is long not short) Â And Nikon you're right, the mosfet should know exactly when to stop for the burst so it should be good. With all the parts I bought for it it should be PAST 30 rps going to be fun. Quote Link to post Share on other sites

With all the parts I bought for it it should be PAST 30 rps going to be fun. Â I'm getting about 15 rps with a 120 spring and a high torque motor. What type of spring and battery are you using?

ericfine50 Posted May 4, 2011 Report Share Posted May 4, 2011 Thanks guys. The local pro-shop here is getting in some SRC motors next week. Any experience with those? Quote Link to post Share on other sites

Seriously, the SHS/Element high speed motor is great and has plenty of torque for an M120 spring. Quote Link to post Share on other sites

Tacitus Posted May 5, 2011 Report Share Posted May 5, 2011 At these power levels, a high speed neo magnet motor like Element or SHS will give excellent trigger response. Quote Link to post Share on other sites

Nikon Posted May 5, 2011 Report Share Posted May 5, 2011 It really isn't needed to pull an M120. Â So what's the downside of a high torque motor with a 120 spring, especially if very high ROF might not be your primary goal? Quote Link to post Share on other sites
Tacitus Posted May 5, 2011 Report Share Posted May 5, 2011 So what's the downside of a high torque motor with a 120 spring, especially if very high ROF might not be your primary goal? Â The only reason for using one at that power level would be if you wanted to deliberately keep the ROF down, but that goal would be better achieved using a lower voltage battery or a computerized mosfet with ROF control. Modern neodymium magnet high speed motors can provide plenty of speed AND torque at the mild power levels being discussed. Quote Link to post Share on other sites

Tacitus Posted May 5, 2011 Report Share Posted May 5, 2011 ...but is there a downside, like wear on gears or battery? Â As with all high performance builds there is less margin for error when tuning. But if you're good at tuning and you use the right parts, you can happily run a gun at high speed for a very long time. Quote Link to post Share on other sites
hmg9194 Posted May 5, 2011 Report Share Posted May 5, 2011 A high torque motor in my build just keeps it all clean and snappy. Sure, a high sped would work but I don't want rps past 40 and with this it will never have power problems. To each his own but it's what I chose to do. Quote Link to post Share on other sites
aznriptide859 Posted May 5, 2011 Report Share Posted May 5, 2011 A torque motor for speed builds is a good idea if you have a good enough battery source - HS motors take a longer time to start up, draining more batter power. Torque motors take less, so if you give enough power you can output a decently good ROF. Quote Link to post Share on other sites

Torque motors take less, so if you give enough power you can output a decently good ROF. Â OK, so generally, a high speed motor will drain your battery faster but give you high rates of fire. It can also pull a 120 spring or less. A high torque motor is more efficient for batteries and can pull 120+ springs but gives a much lower ROF. It's a generalization, but is that correct? Â aznriptide859, when you say "good enough battery source", what are you thinking? Maybe a 7.4v 2200mah 30C Lipo or something bigger? I'm thinking a high "C" rated battery will be much more efficient for a high torque motor. Edited May 5, 2011 by Nikon Quote Link to post Share on other sites
The Jam Posted May 6, 2011 Report Share Posted May 6, 2011 No, modern neodymium motors have the same high speed as their ferrite magnet high speed counterparts. They are built better and have better trigger response. Â Ex: ACM High Torque vs g&p m120 Â Winner=HT Motor Quote Link to post Share on other sites
