Info on the MMM from the I-Hobby show

I also am very interested in the tekin, I already have the little tekin rage system for the mini t and it works great I have never had more fun programing an esc. You can do it with no radio!

[jnev]

So has anyone heard any more info on the MMM system?

[Arct1k]

Nothing - i think they are keep silent until it arrives...

However the sidewinder was annouced a while back and still isn't in the shops :(

Not sure what I'm doing wrong but I've had 2 MM burn up now - one on my MBX5T and one on the e-revo with 4s... They felt pretty cool and FIRE!!!! They burn up better than lipos!

[johnrobholmes]

Yep, nothing. Maybe a few more design changes since ROAR is passing rules to make any castle brushless products illegal for race use. Pity that roar is owned by novak and reedy.

[lincpimp]

I do find the humor of ROAR trying to ban castle products, but the amount of power you can use in a tc is limited by the vehicles and track size. I have had some brushless 10th scale vehicles that were way too powerful to race. I have a feeling that the MMM will be popular in the upcomming 1/8 electric class. I have a feeling that the rules will not be as tight for that class, leading to some extremely overpowered vehicles, and fun racing to watch!

[johnrobholmes]

They are banning products not designed around sensored motor systems (basically the style that the owner companies make). Also, there can be no variable timing. That throws sensorless out the window since by design it has to have variable timing to keep in synch. Sure the mamba max is too much power for most race tracks, but smaller sensorless motors could be used.

We should get together and make our own organisation. Allow real power houses to compete and kick the weak sensored crap out. Don't forget about Trinity. Yes I own a few brushless motors from them, but I haven't forgot the adds they had in the magazines. Now they have lipo and gues what, I'm sure lipos will be ROAR legal too. People should stop attending ROAR events just because they don't want new technology going there.

The castles are not being targeted per say, Its the motors that were not on the bandwagon when Novak and LRP proposed the rules. What i mean is there have been rules set to allow any manufacturer to try for acceptance. Here is some of the rules;

8.7.1 Modified motors must conform to technical specifications in Rule 8.4 above
8.7.2 The base motor may be modified by re-winding, epoxying, balancing, adding cooling
holes, ball bearings, and custom brush systems. The original armature, commutator,
magnets, motor can, and endbell must be used, but may be modified. No mixing of parts
from different base motors is allowed.
8.7.3 Approved modified motors must be commercially available through hobby distributors and
hobby dealers nationwide for a maximum retail price of $110.
8.7.4 Rule deleted 2005 (10 turn limitations):
8.7.5.0 Brushless Motors are approved for modified racing only.
8.7.5.1 Sensored or sensorless motors are allowed.
8.7.5.2 The motor has to be rebuildable. Ball bearings are allowed.
8.7.5.3 If the motor is sensored:
It must use a six position JST ZH connector model number ZHR-6 or equivalent
connector with 6 JST part number SZH-002T-PO.5 26-28 awg contacts or equivalent.
Wire sequence must be as follows:
Pin #1- Black wire-ground potential
Pin #2- Orange wire-phase C
Pin #3- White wire-phase B
Pin #4- Green wire-phase A
Pin #5- Blue wire-temp control, 10 k Thermistor referenced to ground potential
Pin #6- Red wire-+ 5.0 volts =/- 10%
For clarification pin #1 is on the left hand side of the above connector with the wires
exiting the top of the connector and the plastic tangs that hold the contacts in the
housing are facing forward. See drawing below.
Compatible speed control must use the six position JST header part number X-6B-ZRSMX-
TK (where the X denotes the style of the header), or equivalent.
The power connector has to be clearly marked A, B, C. on both speed control and motor.
A for phase A
B for phase B
C for phase C

8.4.2.1 Only industry standard “05” size motors may be used.
8.4.2.2 All motors must have the original manufacturer's logo or name molded or etched into the
end bell.
8.4.2.3 Can must have the original manufacturer’s logo, name or mark.
8.4.2.4 Overall maximum diameter: 36.02mm measured at whatever point yields the maximum
dimension.
8.4.2.5 Maximum length: 53mm measured from the mounting face of the motor to the furthest
most point of the end bell, not including solder tabs or lead wires.

From what i can see of the rules i posted, the fact that the castle motors are not truly rebuildable by owner and there are no stampings in either the endbell and can are what makes them illegal. I also think that ROAR prefer the wye winding over the delta wind, but i couldn't find that in the rules. Honestly, I don't see it as ROAR factoring out castle, I see castle going with the basher crowd and letting the tracks decide on what runs. I run three setups (4600 in a T4, 5700 in a B4 and a 7700 in an academy SBV2pro), The only way i'd trade for a Novak or LRP, is that someone shows me they are faster and better than what i got

With those motor specs, you can count NEU motors (especially the 1515's) out of any ROAR races...

It seems Mega motors would comply though

[squeeforever]

ROAR rules are nothing but BS.

Does ROAR even have rules for electric MT's, 1/8ths or any other car that would use a 1515? Just about any motor commonly used for 1/8th's or MT won't fit their rules.

According to a thread on RC Tech, Roar is building a committee, to look into a rebuild of the electric classes, to bring them up to the levels of the Nitro ranks. This will include an eighth scale electric (buggy and truggy class) and possibly MT as well. The only reason i am watching so intently, is because my track is ready to get into an organization and they are looking at a few to join (top of the list is ROAR, RC Pro and the eastcoast Nitro series), but if they go with ROAR my lipo's Might be outlawed till legalized, and my mamba maxxes might be illegal to run, with current rules.

Personally, I have always been in favor of "run what you brung and let the skill be the difference", Too bad that others don't like them rules (ROAR and the like)

[Patrick]

Woops.
