FE Calc shows roughly 112 amps with Octura x447 prop, and 75 amps with x442. 138 amps with a x450. Low to mid 40's with all. Thats on 4s, (14.8) 5000mah lipo's. Probably not as long a run times with nihm's and they will get hot the more prop you go.

Awsome, glad to have that settled, guess i'll go with the 4074 1800KV motor, sounds like the best of all worlds! If i run the x442 (i have a few of them) at 75 amps, the NIMH batteries shouldn't get much warmer than they do in the Spartan, sound right? Actually the Traxxas PowerCells get very hot in the Spartan, but my DTX5000's only get warm-meduim hot, and are faster (shorter run time tho). Looks like OSE has quite a few of the 1800's in stock, i'll be ordering one up real soon. Thanks for the help!Comment

If my memory serves me well, the original motors were 1600kv. No one really knew what the ESC rating was. With the new Castle products, the motors are 1800kv and no one still really knows what the new ESC is rated at!
. I know on my Spartan with the new stuff the batteries get hot but run times are about 7-10 minutes if I just goof off. Quite normal for Nihm packs. But the warmer they are the more power I get. At first launch, the boats gets up pretty good but wont jump. If I run her for 1-2 minutes, then bring it in for about another minute and then take it back out, it will launch hard and leap. With the lipo's she'll almost do a flip. I have a prather ss220 on her now and she smokes. No GPS yet as I'm giving her a clean paint job but in the next week or so I hope to on 6s, 5000mah 30c packs.

Same expirience here! After a couple minutes the Spartan runs it's best! I just got my Castle motor and ESC back from Traxxas last week after my origional system took a dump after getting wet. Thanks to crappy weather i have not been able to run the new Castle electronics, but over all no matter what i love my Spartan. It is great at the lake and takes chop really well!! I'm looking foward to trying lipo's in it as well next season!If my memory serves me well, the original motors were 1600kv. No one really knew what the ESC rating was.

You'll like the new stuff! It performs well! Traxxas support was cool enough to put my aluminum jacket on that I purchased from OSE. And they clipped off my EC5 connector off the old ESC and put it in a plastic bag and gave it back to me! Not that it was a big concern, but I was surprised. Paintwork is done except for the clear. 2 more days of dry time and then some scuffing with a 3m pad. Wash and dry and clear. I'm excited! It wont look like a Spartan in color, just profile!Comment

Yeah I was a little worried to send my motor to Traxxas with a $20 aluminum jacket on it but they assured me they would re-install it, and they did! You are right, their customer service is great, even tho I had to wait over a month to get my parts back, still can't beat free new electronics! Hopefully I'll get a chance to run the Spartan before the season is over.Comment
