Default Thoughts on my servo choices?

SC-1256TG for throttle:

Dimensions(mm): 40.3x20.2x37.2
Weight(g):52.4
Speed(@4.8V sec/60): .18
Torque(@4.8V oz-in): 222.2
Speed(@6.0V sec/60): .15
Torque(@6.0V oz-in): 277.7
Gear: Titanium & Aluminum
Bearing: 2BB
Case: Aluminum
25 Tooth Spline
Frequency: 250-333hz
Pulse Width Frequency: 1520


And SB-2273sg for steering:
Dimensions(mm): 40.3x20.2x38.5
Weight(g): 69.0
Speed(@6.0V sec/60): .12
Torque(@6.0V oz-in): 319.4
Speed(@7.4V sec/60): .095
Torque(@7.4V oz-in): 388.8
Gear: Unique Steel
Bearing: 2BB
Case: Full Aluminum
25 Tooth Spline
Frequency: 250-333hz
Pulse Width Frequency: 1520

I plan on using a LiFE 6.6v pack to drive them, my question is, is the throttle servo fast enough?

Throttle might be a tad slow for you depending on you driving style. If you want more instantaneous throttle/brake control then you might want a faster servo for it, but personally i think those are great choices.

What's good for torque on the throttle/brake side? I'm looking to maybe go HV now - so I'd like to get an idea of what else to consider.

I'm not a fan of the Savox servos and especially the LiFe batteries if you have a receiver that is LiPo friendly. The Savox servos just arent that reliable compared to other options out there. If cost is a concern, check out the Hitec 7955s, they're priced very well and perform exceptionally well (specs will seem low but remember they're rated at 6v but work great on LiPo).

I get that some people aren't fans.

I haven't had any issues with them, and have had good experiences, so I've stuck with them.

Flip side - years ago a buddy had a Hitec fry on him on it's 2nd use, so I've stayed far away.

I ended up pulling the trigger on the SB-2274SG.

Here are the specs:

Dimensions(mm): 40.3x20.2x38.5
Weight(g): 69.0
Speed(@6.0V sec/60): .105
Torque(@6.0V oz-in): 277.7
Speed(@7.4V sec/60): .08
Torque(@7.4V oz-in): 347.2
Gear: Unique Steel
Bearing: 2BB
Case: Full Aluminum
25 Tooth Spline
Frequency: 250-333hz
Pulse Width Frequency: 1520


I'm actually agreeing with you on the move to the LiFe packs - I'm now thinking I need to order a lipo receiver pack.

Any recommendations on receiver packs? I don't have any opinions on them, as this is my first foray into nitro in 10 years.

Hope they work out for you.

As for the LiPos, just stick with a reputable manufacturer and you'll be fine. I've had good luck with Reedy packs over the years. Have a TrackPower in the Mugen right now and I'm not impressed.

Thanks! I respect your posts a lot, and follow a lot of what you say. If the Savox stuff doesn't work out, I'll definitely check out the Hitec's.

Can you link me to the Reedy that will fit in the MBX7R?

I would think the torque you would get from the servo you have specified should be plenty

You'll want something close to 85x30 x17 mm. Anything around 2000mah is plenty to keep you going for quite a while (Savox servos are a bit hungrier than most).

Protek
Reedy
LRP (might be a bit tight length wise)

LRP battery fits perfectly , have one in both buggy and truggy . They work great . I charge the night before a race day but dont have to charge during the event . We run 2 ,7 min quals and then 20-30 min mains plus practice.

I would suggest charging at some point during a race day even if it is just before the main.

I run Savox servos and have in ALL my cars for the past 3 years. I have had GREAT luck with my Servos and one just went out on me after 3 years in my TRUGGY. Most of us know that Truggies are the hardest on Servos.

I have a total 12 Savox servos installed on my cars right now and I have not had any issues.... I think 3 years on one servo is plenty. I feel that I have gotten my moneies worth out of ALL my Savox servos....
