Brushless CRT Questions

No problem.

Still, I think the 10XL on 4s (or 12 cells) would be the thing you are looking for. It's more efficient to run higher voltage on a higher turn motor since there is less current draw - and the MM will stay cooler too because of that. Gear it conservative and it should be a very stable (temp-wise) truck with more speed and power than the Titans with the hassle-free maintenance you want.

And even though you don't want to deal with locking the tranny, I think you'll find yourself leaving it in 2nd gear because 1st is honestly just useless. And removing those extra parts (shift servo, linkage, shift fork, extra gears) makes the tranny simpler, lighter, and increases reliability.

And as far as the BEC goes; even at 3s, the MM will generate heat because of the BEC. I always recommend a switching BEC at anything over 6 cells/2s. Say you're running 3s and servo(s) drawing 2A, the MM BEC will be forced to dissipate over 10 watts of power as heat. That's really a lot even though it doesn't sound like it. The switching BEC takes all that load off the MM and does it more efficiently too (and gets more efficient with higher voltage).

Just my $0.02. Good luck and let us know how your truck runs when you get it done.
