Generally, i guess. That's what Kratons, Kronos etc come with out of the box, but in case of the stock Kraton for example, it comes geared 12/50, with the optional high speed pinion being 15t. That can't be used offroad though. With that 1717 can (it's a 4885ish sized can) i can gear it 21/50, for around 70mph and that's offroad. It's just boatloads more power. That said, i've never liked the 2050 cans - they run absolutely on their limit in a Kraton. thanks for the reply What does '1717' mean? I get how a 4072 is 40mm wide, 72mm long, what does 1717 or 2050 mean? Quote Link to comment Share on other sites More sharing options...

The stock Kraton motor is 2050kv. 1717 is the "name" of castles 1650kv motor. https://www.castlecreations.com/castle-1717-1y-sensored-motor-1650kv-060-0081-00 The stock Kraton motor is 2050kv and 4274 sized - the 1717 is 1650kv and around 4885 in size.

Kpowell911 Posted November 22, 2020 Share Posted November 22, 2020 Ah, I thought that mabve 1717 was 1.7" (as its American). I've personally never rated Castle stuff (other than their VERY FIRST stuff) so never gave them much time. Fodo for thought however.... Only started looking at the EXB (As with my original choice..... Max 6 & 2200kv and a £50 Savox) came to less than a 4S Traxxas Maxx haha.... Then I carried on reading about the exploding diffs, so never mind! Quote Link to comment Share on other sites More sharing options...

Then I carried on reading about the exploding diffs, so never mind! No idea why they're named so stupid/confusing. That motor (together with the ESC it's supposed to go with) is probably the best available combo for 1/8th currently, if you can bare the price tag. By no means is this a "necessary" combo for the EXB, but i do want the data logging and smart sensored capabilities (it switches between sensored and sensorless on the fly), not to mention thermal protection for the motor since it's going to be somewhat of a wild build. In regards to the exploding diffs, that's fixed with the new batch. Though, it doesn't have an open rear anymore now, it runs an x1 LSD (centre and front are x3 LSD). The open rear was the problem, because tolerances in production were off so it wasn't shimmed correctly - which now with the LSD plates isn't necessary (or not more necessary than any other diff) anymore. I'm with you on that, that's the reason why i didn't buy a release EXB - but the second batch (12-16th of december) is fixed. edit: i'd run the max6 with a 4985 in a Kraton EXB tbh. Much better.

Kpowell911 Posted November 22, 2020 Share Posted November 22, 2020 Thanks! Would a Max 6 fit? Its a chunky fella..... Quote Link to comment Share on other sites More sharing options...

Absolutely does, though requires a small modification in the tray. There's a lip on the ESC tray that you have to cut/dremel down, 2 minute job. Holes don't line up, so it's either double sided tape or you message @Paul Busby and have him print an adaptor plate. Or hell, if you decide to go down that route, now that i'm not gonna use the Max6 in the EXB, i'll send you mine. 1 Quote Link to comment Share on other sites More sharing options...
.AJ. Posted November 22, 2020 Share Posted November 22, 2020 The Max6 fits fine with a little work, this is the Mojave EXB, but it’s the same layout as the Kraton 👍 Quote Link to comment Share on other sites More sharing options...

.AJ. Posted November 22, 2020 Share Posted November 22, 2020 Its a must for the Mojave and a Kraton with bigger motors, you are limited to a 23t pinion with the stock motor mount, I’m on a 22t already and the PPS mount will allow up to a 31t to be fitted 👍 Quote Link to comment Share on other sites More sharing options...

My EXB is going to be a basher, not a speed running vehicle - i don't need to gear it for 80mph+. Quote Link to comment Share on other sites More sharing options...
Paul Busby Posted December 9, 2020 Share Posted December 9, 2020 The Max6 fits fine with a little work, this is the Mojave EXB, but it’s the same layout as the Kraton [emoji106] Actually the Mojave has a different layout. It has a rotated servo and as the front -> centre drive shaft is longer, it has more space for an ESC. I've managed to fit a max 5 on the Mojave chassis.You can still fit a Max 6 in the Kraton fairly easily, just thought I would get my quota of pedantry in for the day. That PPS mount is pretty sxy i have to say, hm..I fitted one to my Kraton last night [emoji6]It is superbly engineered and machined, the highest quality aftermarket parts I've bought.I have been working on some prototypes for the fan mount btw [emoji106] Quote Link to comment Share on other sites More sharing options...

m4inbrain Posted December 9, 2020 Share Posted December 9, 2020 3 hours ago, monkeyboy_uk said: What's the score with the rear diff issues on these? Has it been sorted? Yes and no. The first batch of the EXB had an open rear diff, which led to the problems (it wasn't designed as an open diff - it was designed as a limited slip diff, but they took the slip plates out, while not shimming them back up correctly). The "new" EXB (or rather, the second batch) doesn't ship with an open rear diff anymore, but has instead also a limited slip in the rear. Which, fingers crossed, means that they're not blowing apart anymore. Put this way: the fix for the "first gen" EXB was to shim the diff internally to the diameter of the missing LSD plates. The "second gen" diff has those LSD plates. The front/centre diffs hold up well, so i'm pretty certain (of course not 100%, but certain enough to spend my money on it) that it'll be fine now. 1 1 Quote Link to comment Share on other sites More sharing options...
