1515 2.5D (1700kv) is a good motor for 5s, can be geared up for high speeds and is petty good on 6s. I like 5s on the 2.5D for the track, low temps, low power draw, and you can play with gearing a fair bit. Haven't had any problems with my quark since using this motor (no mods on the quark).
I don't think you'll need a $375 MGM. The $275 16018 should be enough for the track and normal bashing and can still do 6s.
I don't know if you'd need mech brakes, unless you want them. I use motor brakes in mine. So one less servo to buy. I thought most of Mike's motor mounts don't work with mech brakes any way, but I haven't looked into that.

The XT8 mount is the first one that allows you to use mechanical brakes. I think the others will eventually be changed over as well.

t-maxxracer32 · 10.29.2007, 11:25 AM

well i have some 645mg servos that i could use for brakes and that will allow me to save some money!

also, i too was wondering why i needed that 375 dollar esc but i figured it was needed with such a big truck...

i have a question.

if i get the 1y and use 4s on it how will that compare to the 2.5d on 5s?

i will never go 6s but possibly 5s.

what would you think the runtimes would be with the 30c 4500 batteries?

You can see what the basic truck looks like on BPP's website. Its http://www.bomb-proofproducts.com/home

No limits.... This is the sexiest truck ever IMO. I would just have Mike build me one and ship it one part at a time untill I had it all bought.

Last week when I raced my truggy (5 or 6 5 minute races in the middle of warm day) my unmoded quark was working well with just the rcm heatsink and no fans, running the 1515 2.5D (1700kv) on 5s, so I would have thought that the 16018 would work well too since people say the MGM's run cooler, but tallyram's truggy that was linked to uses 22418 ($375 one), so maybe there's something I don't know.

I don't have both to compare, but on those voltages the 2.5d should only be ~1000rpm slower, so top speed with the same gearing should very close, but with the higher voltage the 2.5D should have a bit more torque and lower amp draw. Meaning a little bit less volt drop in theory, which could make up the rpm difference and there should be a bit more room to gear up. Basically I think they should be pretty close, but the 2.5 should run a little bit cooler, with a bit more torque and runtime.

BP-Revo · 10.30.2007, 12:40 AM

When possible using higher voltage is better, as it reduces current draw and generally makes stuff run cooler and more efficiently, taking stress off components.

t-maxxracer32 · 10.30.2007, 10:26 AM

alright so the 5s packs will be worht the extra 50 bucks?

at this point 50 dollars is not too much

what kind of runtimes can i hope for?

I don't mean to hijack this thread or anything, but why would a person go with the XT8? I agree it's a nice looking truck and I've heard the kit goes together extremely well, but how about it's racing and handling characteristics? I keep hearing the Losi 8ight-T is the best handling truggy out there. Anyone care to chime in on that? Thanks.
