Go LiPo or brushless?
Discussion
I ordered and built a 2016 Blackfoot a couple of months ago and fancy some more poke out of it. Main options seem to be to go with a brushless motor or LiPo (preferably both but don't fancy spending so much money in one go). I have previously upgraded models with Tamiya GT etc brushed motors so fancy something a bit different.
Seems like LiPo may be a good option as although it's similar price to going brushless (c.£50 for a 3S battery, quick charger and gubbins), it means that I could use the battery on my Bullhead and any other models I might buy with just the purchase of a few £s of connectors and a voltage alarm. Whereas if I go brushless, it's c.£50 a pop each time for a motor (c.£100 for 2 the Bullhead). Plus I'd be replacing perfectly functional, albeit cheap and basic, motors which I feel like I should just run until they die then replace with something fancy.
Thoughts?

I'd go for the lipo if it was me. Better charging times, more capacity for the same size etc.
Are you sure you shouldn't be buying 2 cells though? Which speed controllers are you using?
I have been warned about 3 cells as apparently the diff on Blackfoots (Blackfeet?!) can be a bit fragile. The 2 cell LiPo combo pack is actually £10 cheaper. Is 3 cell a complete non-starter?Are you sure you shouldn't be buying 2 cells though? Which speed controllers are you using?
I have a Tamiya TBLE-02S ESC on the Blackfoot, can't remember what's on the Bullhead off hand...

ETA and use a voltage alarm as you mentioned as the cut off on your ESC is below what's ok for a lipo

If the BlackFoot of today has the same differential as that of yore, it’s worth noting that anything more than a 27t Single Mabuichi 540 was likely to blow it to bits. It was basically a Frog with different body and wheels/tyres.
To get around this, MIP make a much stronger ball diff that replaces the standard weak one. I know this as I fitted one to my sons Monster Beetle this evening! £50 though.Don't go 3s you'll blow it to pieces.
2s will be fine but may also be a little to much. But get a decent esc and turn the power down a little.
Also no need to spend £50 on a motor ebya is your friend get them for about £10-20 and last for ages. Try Gool stuff
