DUFFY said:I would say the motor runs slightly hotter than some people will tolerate in their systems. In this system/gearing no fan yet, that adds up to be slightly hotter than a 1/8th scale castle system does in an e-revo on 4s. And I have no fan on the motor, yet. I am on 6s; if you want to have a cooler option and stick to 6s you could try TP power. They make the same motor, in size and kv. The tp power motor looks like it has vents so it should run cooler just because of that. It will how ever let some dirt and crap in the motor. So what one will last longer I don’t want to speculate. Posts on TP Power motors are all positive that I have found. I heard some people not liking leopard motors but mine is fine. I have ran it so many times its proven itself to me. I will put a fan on it and be ok with this gearing I think. I would like to test 6s2p Im not sure if the castle xl2 esc can take it though, im not going to mess with it. The heat is not much of a problem as it works fine within this run time. Going to 30 mins or more will heat things up for sure. If your racing a gas truck in a short race say 10 min what ever, you will beat them pretty good with this set up. If you race for a half hour your battery changes will off set the time gained in performance a lot. The longer the race the more gas gets a advantage. If you want to do one battery change during the race this set up would work. Maybe plan on two as it will give you a nice cool battery. IF you don’t want to do any battery changes I would buy a bigger ESC and spend some big bucks to run 8s 2p. Going 12s will add a lot of weight if you wanted a 30 minute run time.
It all depends on your goal or compromise on speed and run time/ heat/ being able to control your car. If you run 12s you will look crazy but you will also fly out of control more often than the next guy. Crash once in a race and all the speed really just slowed you down, for how ever long it takes to get the car off the ground and back moving. 12s will also be hard to get to 30 mins other than running four 6s batteries and would be very costly indeed if one of the 6s batts fried and then fried the other 3 next to it. IF heat is a major concern I would go lower than 1340kv its hella fast an the motor and works for me. The TP power motor might be a better bet for you in a lower kv.
So I got my second xb-e in the mail off ebay. Everything looked ok and the esc fired up and beeped loud as hell. I was like wow a used RC off ebay with a working esc NO way I can be this lucky. I laid the buggy out in the grass then gave it some gas. A very horrible sound came out of the center motor mount. The pinion was loose so I cranked it back down with out lock tight just to keep testing. The car moved but it was slow and something was just not right. Looking at the buggy closer I can see some damage from shipping must broke something/ or it was broke before it was shipped. The pin holding the rear hub is broke, letting the dog bone out. SO I was in front wheel drive only. It’s a pipe dream to get a 100% working used RC car off ebay- for me at least.
8s will be your sweet spot with the motor your running, won't get as hot, but run time will be down if only using 2 x 4s batts, that being said, I have found the 1000kv TP/turnigy motor on 6s perfect, you can gear to the moon and it bearly gets warm, long run times to and having 2 x 6s batts in there(positioned as far back as I could make it-extra batt holder holes drilled in the chassis) really balances it out when taking on big jumps, lands perfectly.
If they ever get back in stock...... I have one on back order. Every time I check, it still states "available in 30 days" LOLI have found the 1000kv TP/turnigy motor on 6s perfect, you can gear to the moon and it bearly gets warm, long run times to and having 2 x 6s batts in there(positioned as far back as I could make it-extra batt holder holes drilled in the chassis) really balances it out when taking on big jumps, lands perfectly.
Don't understand whats taking so long for these motors to come back into stock, I emaiedl Hk the other day about it, they couldn't shed any light on it either, their advise was to place a order and wait.............LOLRCDAD said:If they ever get back in stock......

They're just trying to keep people from buying from the compition. I don't mind waiting. I'm one of the -6 their inventory indicates. Lol. I'm lucky enough to have enough platforms to keep me busy while I wait.
