Is the Reedy Sonic M3 10.5 Motor better than the Team Orion VST2 Lightweight 10.5 Motor?

Thank You

chuck_thehammer

not trying to be 'smart'

better at 'doing' what.. and 'in' what.. driving 'on' what..
what battery.. ?

much more information is NEEDED..

GuyIsDamGood

I should've been more specific with the question-topic.

The better On-Road - Asphalt Motor (on a medium size track)?
-run'n Ni-MH-3600 or Li-Po-2s-4000-20c Batteries

I was look'n for Nick Adams to test the VST2. But; I believe he haven't tested it yet.

Which of the two motors do you guys think is better for On-Road - Asphalt?

Thank You

are you looking.for good customer support too...if so, the Reedy!

Im.sure someone has dyno'd both by now. Id ask Rotor Ron.

I ran the Team Orion VST2 10.5 Motor (in my Tamiya TB Evolution 5).
-the Team Orion VST2 is a smoother running motor
-I ran a faster lap-time with the Team Orion VST2 by 1/2 of a second

(it was a cool Sunday morning (44°F; the VST2 didn't get hot after each 5-minute run)
(I want to see if it will get really hot after a 5-minute run in 75°)

In all honesty, I'd have recommended looking at newer/better batteries before a new motor...

GuyIsDamGood

Thanks for the advice-info MarkA.
You have a point. But new/better batteries or new/better motor will basically even-out the better performance.

I chose the new/better motor.

(new/better batteries and motor will definitely increase performance.
- Cost.

So how many different gearing combos and timing settings did you try on these two motors?

How close to the fastest lap times at your track are your fastest laps? If you are noticeably slower, the gain in lap time is probably from you getting lucky. How many of the faster laps have you done since switching motors?

Agreed MarkA
Should be personal preference because both are good motors.
A battery is definitely more important. No nimh will be competitive.

I tried four Pinion settings(34, 35, 36 and 37). - same 96-Spur Gear. I always set the motor timing to 0°.
-the Orion was fastest with the smallest pinion installed

I'm the fastest (so far) of the 9 racers. I'm a consistent .13 - .20 faster with the Orion 10.5 VST2 over the Reedy 10.5 Sonic M3.
Since the switch; I ran 13 faster laps with the Orion.

GuyIsDamGood

I agree. The car runs faster with the Li-Po battery installed. (I used my son's Li-Po battery. I don't own a Li-Po battery. I'm scared of Li-Po batteries. . . . . . . . . .fires)

That's not a fair comparison. Different motors have different optimal timing settings and gearing settings, and often have different built in timing values when the can reads zero.

GuyIsDamGood

Hey gigaplex; thanks for the info. You have a point.
-the Reedy Sonic M3 10.5 came stock with 20° timing
-the Team Orion VST2 10.5 came stock with 0° timing

I'm go'n to set the Orion VST2 with 20° timing and attempt a fastest-lap.
(will it be worth it to reinstall the Reedy Sonic 10.5, run it with 20° timing(stock timing); then try to get the fastest-lap?)

Timing and gearing change the load the motor creates. Turning up the timing or gearing up (larger pinion or smaller spur) make the motor ask more of the batteries. If you are using NiMH batteries, they can't give any more. If you turn either motor up, they will probably get slower because the NiMH batteries can't handle either motor turned up.

There is also the possibility that even if you could get more power, that your lap times won't go down because you are not a good enough driver to use the added power. Or you are already at the maximum power that is useable for the track where you run.

Is this a prepped track with a timing system, or a course you and some other people have set up and a stop watch for lap times? Because, if you are trying to make decisions based off of lap times, you need an accurate timing system where the lap times start and end at the exact same time, and a track with very consistent traction levels.You also need the ability to drive very close to the fastest lap you can all the time. Getting a fast lap once, and not being close to that lap means you got lucky. Being able to turn laps close to your fastest means you are close to the limit. If you can drive close to the limit consistently, you can make adjustments, and see if the limit changed.

This is all stuff I have learned over my 28+ years of rc racing.

And when I say close to your fastest lap I mean 0.1-0.2 seconds off. Which, if you don't have a very accurate timing system, there is no way to get lap times accurate enough to use lap times as a measurement of performance.
