Insight into 2350 Flux equipment?
 

Hey Patrick, im dying to know some more details into this new Q-base ESC and Alpha star motor for the Savage 2350 model. What can you tell us about them and some comparison differences compared to the Flux MMM other then 4s vs 6s so I can pass along the info to other people interested in it buying a 2350 vs a HP. Thanks!

Err a MM Pro with a different sticker and a smooth can motor that is between a 1515 and 1512... I'm guessing its a 1514 1Y

Or a 1415...:whistle:

The MMP can handle 6s though....

Or only 4s? Not sure?

MMP is 6S but with this 'hotter' motor and its in a MT they are saying 4s to provide headroom.

Incite should be spelled insight.

Incite means to stir up or put into action, such as "To incite a riot"

Any reason why they are doing this? Seems like a step backwards. I guess there are alot of people who are just fixated on 4s being the best thing since sliced bread...

Would have made more sense to stick a 1600kv motor in the flux and max a true 6s capable truck, geared for 45mph or so and pushed toward the serious bashing crowd. Like a "Savage XD" or something like that. Of course the savage platform is a bit weak in some areas so maybe not a great idea...

Maybe educate people that higher voltage and lower kv is better...

They did it so people can buy one for $500, instead of $640.

They could put a tamiya silver can and a mech speed control and rate it for 2s... Sell for about 300 bucks then... I guess people with no idea will buy them like hotcakes.

My guess is cost. the ESC looks identical to MMP, no doubt, but the motor... I am not sure Patrick makes it. HPI might has found a more inexpensive Chinese motor with okay performance.

It might be one of those top-secret motors he couldnt talk about around the same time 1518 / 1717 was being released- some info would be nice though on that motor for sure..

IMO it's not a Castle motor, look at the endbell fixations screws : lateral screw (very fragile system).
I would bet on a low cost chinese motor like feigo or hobbywing EZrun motor...
HPI marketing... Another big toy RTR, "Ready to Repair" :whistle:

The ESC is a Mamba Max Pro, HPI special version.

The motor is a low-cost version 1517. (a few changes from the standard version to make it much lower cost to produce.)

The endbell screws are exactly the same as on the 1515 motor -- never seen one broken -- ever. Just we used them on both the front and back of the motor to lower costs (the front-endbell screws moutns on the 1515 are really expensive to machine -- lots of time on the CNCs)

wait; so this motor is LONGER than the standard flux motor? why is the kv higher?

Cheaper magnets... :) Kv goes up with lower power magnets.

It is the same screws of the REAR endbell I meant, the front endbell on the NEU-CC 1515/1y has stronger screws longitudinally mounted. I thought you change the system on the 1:10 scale motors for this reason, sorry.
I broke a motor front endbell with this system (ORION 2300Kv 4 poles), but the motor was hold by the front endbell, if in the HPI chassis the motor is mounted with front and rear fixation they should be no problem...

Also, the front end-bell is glued in place, so there shouldn't be any issues. :whistle:

Awesome, thanks Patrick!

I am very happy with Castle Stuff, but I had a bad experience with one of this lateral screw on my 1520/1Y :

looks like you over tightened it and had the screw head pop off. Could have been a defect in the screw

It happened when I tried to unscrew it, there is blue loctite in here I think, pretty tough to unscrew it. I will be annoyed when I will have to change the rear bearing next 2 or 3 year :lol:

What is it that limits the 2350 to just 4S then - MMP is 6S rated??

Rated to 4 cells in the Savage -- the 4 cell rating is specific to that application.

From the picture it looks like the Q-base esc has solder tabs on the power input.?

good point -- that is a difference. HPI wanted solder posts on the battery inputs.

Cool, thanks for all the info Patrick, answers alot of questions guys were asking on a few forums that I've seen. :yes:

i have never broken one myself, they always strip before you can do that:lol:

Be aware -- those are TORX screws, not hex screws -- if you use a hex driver, you might strip them...

I really like that the Q-base has all solder post connections. I wish the MMP was available in this configuration. It's nice to have the motor solder posts on the MMP 1-cell, but then you give up the fan and internal BEC, and the battery wires are still soldered to the board.

Is there any way to buy the Q-base as a stand-alone item? Contact HPI? Or look at the RC "chop shops" on Ebay?

I believe HPI will be selling the Q-base as a stand-alone product.

Thanx!

So given a bone stock Flux HP and Flux 2350 with the exact same 4S lipo's installed in both and ran them side by side, what would we be looking at as far as performance comparison?

Really a question for HPI -- I don't know... I've never driven a Flux with the 2350 motor in it. :)

Well is a marginally faster motor - so on 4s it will be slightly quicker and you probably won't notice any torque difference as its still a fine motor I'm sure.

However you can't do 6S or 5S without invalidating your warranty which is where the MMM / 2200 will win.

Fwiw, look at the diff in motor kvs 2200 at 14.8v = 32560rpm, 2350kv => 34780rpm, using BG's gearing calc (after verifying it reproduces the 42mph on 4S for a 2200) this diff in RPM nets the 2350 Flux an additional 2.9mph mph, 44.9 vs 42.0mph for the Flux HP. I know my Flux will pull the gearing, my gps says it does. I asume 2350 will also.

If you bump HP to 5S, it runs away from a 2350 at 53mph per BG's calculator.

I have mixed feelings on HPI doing this and obviously of there are issues I would assume HPI has been warned and it's in there hands.

It's okay I guess for someone who wants a light basher for under 500 but I just see too many potential issues. Given all the newbs who burnt up their MMM's in the original flux this just gives me warning bells.

Maybe there is something I don't know here but I would opt to the MMM/2200 for sure. I would even go for something like a Holmes ESC (which castle makes) running a 775 on 6s over the MMP on 4s with the given motor.

In fact I have been thinking about a waterproof revo with that setup as well since JRH will sell the ESC waterproofed as well.

I have faith in castle, just not in newbs.

Actually, it's a pretty good setup. The MMP is really good at protecting itself -- better than the earlier MMM was. :)

And if you limit to 4 cells, no issues at all.

Well, I haven't pushed the MMP seeing as it's in my Losi Comp Crawler running a cough novak cough motor. Hey the sensored really helps in a crawler.

What do you think about running the Holmes Torquemaster on 6s with a 775?

I had a random thought, will the Castle link or field link work with this rebadged ESC? That would also be a big determining factor I think for peeps. Does the sensor port even work also?

I've never used these series sizes , only ever used kv and diameter and length to spec motors.

What do these terms 1517 , 1717, 1512, ect mean?
What dimensions is the 2350 HPI motor? or what size is 1517?

Thanks.
