Has anybody out there experienced the 24-48ips CP motor made for the Eclair ACL?.

If you're trying to bring back from the dead an old outboard motor for the ACL , I would just recommend scrapping it and getting a motor from Tobin Cinema Systems, they're the best in older camera syncmotor systems

Thanks. They don't seem to have anything for ACLs, though.
I am just wondering if the 24-48ips CP motor is as powerfull as the original Eclair 12-75ips motor. I'm concerned about the 4OOft mags and battery drain.

Yes, you are right to be concerned. CP modified original ACL 1 and 1.5 motors to go under and over 24 fps, which is the speed they were designed to run at. CP modified motors are not "heavy duty" as the ACL 2 motor is, or as expensive and hard to find. This motor will run 400' loads with ease and will not flicker as the older and/ or modified motors did when strained by the larger loads. This generally would happen in longer takes, after a couple of minutes of the camera being run without stoping. On shorter takes (around a minute), done after the camera motor has cooled down, you may be able to get away with not getting flicker.
I own an ACL with a 8-48 fps CP modified motor. The previous owner claims it runs 400' loads flickerlessly with the supplied 400' mags. I have no reason not to believe him, but I sincerely doubt it can keep up. I have not put the modified motor to test myslef, however, as I also own 3- 200' mags and prefer using them. I shoot short ends or A-minima 200' loads with it, though. For 400' loads I use my Aaton LTR 7, which has no problem keeping up, of course.

I don't know about the battery drain, though. My battery is a huge custom made Powersonic block that, aside from being big and heavy, simply rocks on long and steady power supply chores.

Best,

Saulie

Thank you Saulie, that's very enlightening. I think I'll wait for an ACL2 motor to come along.

Clive Tobin discontinued his ACL motor years ago - I don't think it was cost-effective for him to make them given the number of ACL's in use. I obtained one new for much less than the cost of a used CP or ACL2 motor, but the Tobin motor is considerably bulkier than those and noisier to boot. Does the trick, though.
