6S CRT.5 Neu motor question

[VintageMA]

Jeff - that was an awesome idea with the reconfiguration of the LMT - thank you very much!!

A little tricky reconfiguring the solder joints but I got it done and made sure the solder was nice an thick to avoid creating a fuse as per your old thread from last summer.

Went back up to a 17/46 (~39mph) gearing and with 4S pack measured peaks around 30 Amps just boogying around the house (whereas I would hit high 40s with the previously described config).

I probably won't get out for a real run until the weekend, but I am very excited with a setup that may work great and save me ~$500+ in the long run.

The big bummer is that my order for a Neu 3900mAh 3S pack just came in - don't know what I am going to do with it now, but maybe hang onto it for some ~30mph running around - probably get some long runs with it now.

Once I get a full run and can check the amp peaks and am sure this setup will work I then ned to find a nice 4S pack that will balance out well with the vehicle. The motor (230g), servo (60g) plus heat sink and fan come out to ~300grams. I had gotten the Neu 3.9Ah 3S pack cause it weighs in at 306grams and almost balances out the motor side of the vehicle perfectly. Maybe a NEU3200XP 4S (337.5g) or a TP3300 eXtreme V2 4S (351g) - both rated 25C.

I am currently running a novah hv 6.5, with a MM on 3s lipo. I had a maxamps 4200 pack, and it puffed first run. Kind of disappointing, as I had a 15t pinion in it, and it was not that fast.

Having changed almost every vehicle over to 5s, and recently making a few 8s trucks, I can say that going back to 3s sucks. I would almost say that if you can, go to 5s lipo and an 1800kv-2000kv motor. Gear it for 45mph, and the performance will be great!

I have a LS10, which is almost identical size/weight to the .5 with the ext chassis and truck tires. I ran a hacker c50 14l on 3000 5s lipo thru a quark 65 and it was ridiculous.

I am sure just stepping up to the 4s and lower kv will make a huge difference. 3s just seems to run at the edge of what most appropriately sized batts can provide. I plan to run a 5000 neuenergy 3s 25c pack in my .5, but need to move some stuff around. Then I will gear up to a 17t pinion, as the 15t is a bit slow, but that may be my 2100 3s maxamps packs (2 wired in parallel) dropping voltage under load.

Cool. Hope it all works out well. Let us know.
