Height to the center of the center diff from the chassis is 1.050".

I got the hw 2000kv 150a esc and upgraded to a tekin rx8 2050kv and what a waste of time the hobby wing was quicker.I want something with plenty of guts cause at our local races us electric boys run with the nitros.I been considering the mmm with the 2650kv neu motor on 4s should have plenty of grunt

Ya, that is what I was afraid of. The height of the RC8 rear input shaft is only 18mm (0.709"). That could be a problem Thanks for the info.

Default Castle 2650kv Cogg free sensorless system. vs less efficient sensored systems.

Shano,
the Neu/Castle 2650kv(sensorless) powered by the combo Mamba Monster(sensorless) is insane fast on three cell lipo, that's what I run on big tracks and I've never seen a nitro buggy keep up.

Also keep in mind, it's been explained to me that sensorless motors are more efficient, use less energy than sensored. Also keep in mind that the 2650kv castle with Mamba monster esc, this system is not your typical sensorless esc, it resonates at a much higher frequency(than other cogging sensorless esc's) allowing for smooth and cogg free operation. That's why so many people run the castle sensorless system. All this was explained to me by several professionals in the race industry, and varified by castle creations tech support. With a four cell, your car would unglue your tires. Fast enough? Hope this helps.

Cogging is a word That basically translates into a sensorless motor/esc sputtering, and having a rough take off, rather than smooth. Note this does not apply to Castles sensorless systems because of the extreemly high resonating frequency of the design. Tim Bump also explained this concept to me, at Nitro House. He's the head designer of the Hyper 9e, and in the know about castles smooth sensorless operation. As an example of Terible cogging, did you ever see or hear a losi 8ight take off from a stop, back when they first came out with the 1.0. Software upgrades have helped the losi Xcelorin system, but it's not near as smooth and reliable as the Mamba Monster. I've sent my Mamba Monster ESC in for repair three times in one year of hard racing. And zero fires. I use to run novak until it burned my buggy up. The castle esc will just stop when it's done. I understand it's failure rate to be much less than the new Tekin Motors and ESC's. Though Tekin I'm sure will work the bugs out soon enough, it's their first version in 1/8th scale. Castles Mamba Monster is on Version number three. That's allot of time to improve a product, and castle has. Also keep in mind that Castles motors are made by Steve Neu, many say he's the finest motor designer in the world, or at least among the finest. As a side note, the 2650kv motor design is made to last ten years, that includes the truggy 2200kv motor as well(this was explained to me by the Engineers that help design the motors)also keep in mind that castle sells a rebuild kit for these motors for only $25.oo dollars, comes with a new rotor, and two oversized bearings. All castles motors and esc's come with a one year warranty, after one year; it's a flat fee of $70.oo for another year warranty on your exchanged or repaired esc. Now go smoke some nitro's Shano. And tell us all about it here on the forum. Pictures and you tube video links are welcome.

For most mah for a 4S, I really liked using my PolyRC (basically a polyquest battery) 4S 6000mah battery pack. fits the battery tray like a glove, excellent runtimes, extremely good quality cells. Only issue (may be an issue for you), softcase.

For longer run times at lower prices, try using Hyperion 6500 batteries. Unfortunately, they are out of stock right now.
