Those temps are really good for that speed and runtime! I would keep it right where it is. Makes me want to dump the MM motor for an XL basic, or maybe a 1920/7 (but may be a tad too small). I'd really like to go with a Basic XL 4200 or 3600. I guess I'm gonna have to call Mike and beg him to get one. :)

I'm running 50k in the center. It can wheelie but I have enough weight pushed forwards that it's not a real problem unless I really get on it.

Brian, those temps are with the 10L not the XL3100, sorry my post might have been hard to read:002: . I was just asking if you thought the XL3100 would be over geared with that pinion. I have yet to run the XL3100, but I'll hook it up tonight though.

Bye

lol, ok. Well, why not simply leave that motor in there and sell me the Basic XL? ;) Seriously, I think they are about the same size, but the 3100 is probably a bit more efficient.

I have to test the motor for you don't I:005:? Also, the basic XL is nearly the same size as the MM motor and about 1/2" shorter than the feigao L sized motor...

Bye:018:

Yup, you do need to test both. That way I know what I need to get. :)

Brian, I finally put the Basic XL3100 in the .5. I ran it for about 15min and temps were as follows: Motor 145f, ESC 137f, Lipo 110. I think that was pretty good considering that it was geared for about 50mph(20t pinion). Also, this motor geared with a 15-16 pinion should be right on the money on 3s. I put the 10L back in right now until I can get a smaller pinion.

BTW I put 10k CD oil in it and it still wheelies(but less than before). I'm going to get 5k and see if that helps. Also, the 10L has noticeably more torque than the XL3100. I think that an L sized motor or one of the new Lenher XXL motors(are they even out yet?) are really what you need for this truck.

Well, that's kinda good in a way as an L motor is cheaper than a XL Basic motor. :)

Yeah, I think I'll only run the Basic XL3100 to race my friend who has a crt.5 with a OS .18tz!

Bye:018:

Hmm. Mike only has the 9L in stock. I was hoping for a 7L since I'm running 2s. Hopefully he has more laying around that's not listed in the store.

Brian, I ran the crt.5 again with the 10L and maxamps 3s 4000 pack. I hooked up the eagle tree to it and found some interesting numbers. Apparently the 4000's are not really 20c, more like 10-12c. Disappointing to say the least. What do you think, here is the graph. 64 amps and the pack voltage drops down to 9.7! I thought these were supposed to do 80 amps continuous, 120 amps sustained, and 200 amps burst...

Wow, that IS a pretty good size dip of 3.23v/cell. Was that dip towards the end of the pack? If so, it makes sense...

It was just before the 10min mark. I've gotten about 30min out of this pack so 1/3 of its pack life.

Very interesting I'm running the Maxamps 3s 4000 pack in my CRT.5 also and with the Mamba Max 5700 geared for speed runs the pack was getting warm around 120deg and I noticed it melted the shrinkwrap on the end a little? I just got a Eagle tree and need to figure out how to use it? I swaped motors and put a Neu 1506 5000kv in and the highest temps I have seen in the 4000 pack has been 105deg when I get the Eagle tree figured out I want to drop the 5700 back in and see what kind of amps it pulls compared to the Neu? :)

I'm running 1000-1000-500 in mine. I used Jammin Jay's set up for a starting point. I really haven't strayed much other than now having truck tires on it and being brushless. :005:
