I've seen and heard too many horror stories about the instability of the cells, but with proper care and caution I'm hoping to avoid any issues. It puffed up on the third charge while at the track and I had to recycle it after neutralizing it. Originally Posted by LeMieux. Id go lipo first, then brushless.

I agree on the punch and acceleration. I only recently got into RC again after 25 years. I bought a Sand Scorcher for old times sake and caught the bug again and bought an Exo a couple of months later. The Sand Scorcher has to have a hump to get a 7.
It's heavy at about 4. When I got my Exo a laid out the steering servo and ESC so they were both on one side and I could just squeeze my exo mah 2S lipo in the sand scorchers closed radio box. With the Lips in there it has about the same power as the first couple of minutes the Nimh had but never stops for a good 30 - 40 minutes. It's consistent with no drop off till just before the lipo cutoff kicks in.
I don't think the original poster will regret either upgrading the motor or lipo. I don't see why he shouldn't do it in stages rather than all at once. I was a little concerned about lipos but it seems they are a lot more stable than they used to be so long as you treat them with care.
It's hard to say which will be the best initial bang for the buck, my first brushless motor is a 4 pole so no conparison to the brushed motor which is roughly equivalent to a I agree with Antmax, on the switch to Lipo not having to be expensive.
Heck, I spent less on my last lipo pack than I did on the last nimh pack I bought before switching over. The only other question is, what charger do you have, does it have the capability to charge lipo batteries. If not, you don't have to break the bank on a new charger either.
How is it not comparable? I ran a 3s Trinity pack due to the fact that the motor was a low kV. The setup ran really well the few times I got to use the battery, but I am concerned that I may have the same issues with the new battery that I had with the Trinity.
I just want to make sure that the amp draw will not overtax the NiMH packs to the point of ruining them. As long as its safe, I am okay with running them until I am ready to spend the coin to buy a LiPO safe charger, charge sack, fireproof storage box, batteries, and low voltage cutoffs.
The motor and esc that I am looking at costs about the same as a decent 2s lipo so that was going to be the first step. Also, like I said before, the reduced maintenance is also a major benefit.
I wanted to get an 8. Slap an cell nimh in your SC10, and come back and we'll talk. Yet another post that Wtfchuck has destroy by being a know it all lol.

Nimh doesn't have the punch a lipo has. A lipo can discharge faster with less of a voltage dropoff so when you go from a standstill to full throttle you'll notice it. One thing you might want to watch out for is your nimh heating up. Afaik they don't make an 11 cell nimh for an rc. Lipo fires are very rare. I've never seen one go up in flames in person. I've seen 1 smoke and puff but it was a result of a speed control failure.
Something else to consider, Lipo's are generally lighter than Nihms. I recently made the move from nihms to Lipos myself in January, and so far, Im very impressed with the better performance. I put my batteries inside two lipo sacks just in case. BB code is On. Can you provide us with the motor model? Yes Ebram , of course. Hey Mahr , A LiPo cell has a nominal voltage of 3. For the 7. This is sometimes why you will hear people talk about a 2S battery pack - it means that there are 2 cells in Series.
So in this case the motor can operates with 7. Also you can check the specifications in this link Hopefully this answered your questions, feel free to ask again if you have more questions. Ah so would that mean about 8 NiMH cells 1. Alright Ebram , thanks so much for all the info. Helped a crap load, wish you the best!
