Well, you're not getting any first hand information so I'll pass along
some of my observations.
The LeMans series is the most popular brand (Kyosho) with our club.
They are readily available, reasonably priced, and appear to perform
well.
In 1/12th, the 480S and 480T are heavily used. I've seen a couple of
the Tamiya Technituned motors and a few Trinity's. I use a Tamiya
Black motor. None of the above have a clear power advantage on tracks
where the straights run about 120'. More important is the motor's
"drivability", a smooth power curve, even at the sacrifice of peak
power. I have not heard any complaints from the owners of any of these,
nor have I seen any motor failures. I have seen a driver have a lot of
trouble using a LeMans 360 (I don't remember which one) because of the
"peaky" nature of the motor. On the first resistor band off of neutral
it would spin the tires, not very subtle.
In 1/10th, the 240x and 360x are the most popular (the modified heats run
4 minutes). The only LeMans failure I've seen was a 240S seized with a
melted endbell, so I would suggest buying one with an aluminum endbell.
I believe you can retrofit them. The fastest 1/10 modified (6 cell) I've
seen was a fiberglass panned RC10 fitted with the 360G. Considering the
cost of the Trinity's and Reedy's, the LeMans motors are a bargain.

Hello,
One thing to keep in mind, is that the Lemans 240 will only run
about 4 minutes (240 seconds=4 minutes), so if your races run longer
than that, or you like to drive in the yard, etc., your running
time will be limited. Your driving style will also have a lot to
do with running time, I have seen Lemans 360 buggies run batteries
dead during a 4 minute race, when driven hard. If your buggy is
4 wheel drive, Your time may be even shorter. I also know that
the Lemans 360 is not strictly legal in the stock class because
it has an adjustable end bell (timing). I don't know if your club
is strict about this, or if you are planning on running in the stock
class, but I think that the Lemans 240 may be of the same type
case. I am very impressed with the power of the Lemans motors,
especially the 360, but have seen many guys break gears, etc.
when using too much power during jumps. I guess you always
have tradeoffs.
Good Luck,
Lorrin

| I'm one of those who can't resist a bargain, so when I saw some surplus
motors advertised for $3.50, I decided to try them out. I figured I
could always rewind them if they were unusable as delivered. When they
arrived (I ordered three) I noted that they are externally identical to
the Thrustmaster 550 in my Electricub, including the iron ring.
Preliminary tests revealed that they draw about 22 amps static on
twelve cells with an 8x4 Tornado prop. As it happens, that current
drain is a close match to my geared Astro 15, so I just bolted the
motor into my Amptique and went flying. Power seems down some from
the 15 with its 12x8 prop, but more than adequate to haul the
Amptique around at 1/3 throttle. I don't own a tach yet, so I can't
give you a more meaningful evaluation of power output.
If you want a cheap power plant for sport flying, these might be just
the thing you're looking for. They are available from :
ALL ELECTRONICS CORP., 1-800-826-5432. The catalog text follows:
Mabucci#RS-550, Powerful little DC motor similar to those found in some
remote control cars and boats. Operates on 3.6 to 15 Vdc. No load
reating: 12,400 rpm @6 Vdc 0.7 amps. At max efficiency: 11,300 rpm,
3.87 oz/in torque. 1.46" dia. X 2.24" long. 1/8" diameter shaft with
brass gear. Threaded (4x40) mounting holes in front on 1" centers.
CAT# DCM-23 $3.50 each
