Some questions about a few different projects I'm doing (1/6 MT, 1/6 Magnum & MP777)!

[1] I am going to build a brushless powered, twin-vertical-plate chassis, triangulated 4-link suspension, rock-crawler style truck out of the 1/6 Jesse James truck, using large 8"+ Imex Jumbo Kong tires, kind of like NickRummy did, but mine will have a few differences. I am going to build a totally custom chassis and 4-link suspension, and run a 2-speed 3906 E-Maxx transmission with all titanium gears (both input gears, both idler gears, both output gears, the shift-coupler, as well as all of the shafts). I am going to keep/make the truck as true scale as possible, but I do have a couple questions.

What brushless motor should I use? I am wanting a slow enough speed in 1st gear to do some basic crawling, nothing competition-level, but still some cool crawling. And I want 2nd gear to give the truck some pretty decent speed, not uncontrollably fast, but impressively fast for its size...maybe 30-35mph or so. I think I want to go with a sensored brushless setup so that the 1st gear low-speed is smooth and controllable, I just don't know what kV or brand I need. What do you guys think?


[2] The 1/6 Dodge Magnum I pretty much have figured out, with the exception of, again, which brushless motor to use. The entire suspension and drivetrain is going to be Maxx-based, with another 3906 E-Maxx transmission, this one only a single-speed and running Ultramaxxed/OTB hardened aluminum and brass gears. Since this car I want to go extremely fast, 60mph or so, I don't know what motor to run. I don't think it needs to be sensored, but I have a feeling it needs to be pretty big. What would you guys suggest?


[3] Finally, I have a Kyosho MP777, either an MP777 or MP777 SP1. My question is, besides the longer chassis and center driveshafts, what else do I need to turn it into the longer SP2 or WC Edition? The car is literally loaded with every Ultra Racing, Fioroni, & King Headz upgrade parts made for it, but I plan on replacing the shock towers, servo tray, steering plate, and center-diff plate with carbon-fiber pieces, as well as replace all four axles and both center driveshafts with titanium CVDs. I just need to know if there is anything that needs to be replaced, and what, to make it SP2 or WC specs...anyone know?


Thanks in advance for any help you guys can provide, I will really appreciate it!
