Are there any visible differences between the new and old one? Just wondering how to identify the new version when buying (I'm in the UK; import duty will make buying from the US impractical unfortunately).

nobody able to reply us???

So this will do exactly what the motorlyzer will do at a fraction of the cost?

Thanks for all the help.

I don't have the old one but mine did come with a sheet of paper in japanese and English stating 70 deg.

No there isnt anything on the outside of the box that shows this. Email me at [email protected] and I'll see if I can help you.

No there is no way to save any information to a laptop. They said this would drive the cost up to high.

The GForce will not give you individual pole amp draw or give you a rotor measurement like the motorlyser does. Other than that...yes it gives the other info.

Just used one of the new versions today and found out that it does give you the timing reading for,each pole as well as average timing.

Also it will run a 17.5, 21.5 and 25.5 off of a 2s battery and check timing just fine. No need to use a power supply like I thought.

G-Froce is a great little unit. I've come across the individual timing phases and wondering how big of an impact it has on the motors performanc... I've come across motors with +-1 degree and also +-20 degrees。

my buddy has the motorlyzer. we will have to tinker around with them both.I am interested to see how they compare number wise, back to back, same motors.

I just picked up one of these units. It's the one the reads to 50*. I have decided that I will make readings at 40 and 45 as well as 50, and if I have to, I can estimate 55 and 60. Sure it would be nice to actually see it, but I will manage.

Everything I race is 1s, so the voltage tested at is double. It won't run on 4.2v. Again, I will manage. EA: do you think the KV and Amps are linear to the voltage input? Or do KV and amps follow a different curve in relation to voltage? Its all relative, just curious.

The most useful thing I am seeing so far is being able to set all the motors at 50* and see there KV ratings. Fool around with rotor shimming and its effects.

So timing of each hall sensor to the rotor is a new feature? That could be useful as pointed out. I guess you could see the consistency of the sensor board. If you had all 3 sensors firing off at different places, guess it wouldn't be as awesome.

The DB level feature, I first thought: sales pitch. But you know what, it did help me find a bearing that was little stuffed in wrong. I pulled the bearing, cleaned up the seat, installed a new bearing and guess what? The numbers did improve slightly.

I think that I will enjoy the fact I can actually see the timing and not just a random hash mark or some numbers that do not correspond to anything other then a reference.

As some would say: the Bodine-o-meter just got pegged. Time to write some new formulas.

This will be a good tool. Now if I could just couple it with a load.....

I tested out all of my 21.5's motors with timing set at 45*.

Here are my results.

How are you testing peak rpm and kv timewise? I'm pressing the button in s steady rate until I hit full throttle, is that how you're doing? EA responded in his thread about getting a steady reading then he stops it. Just trying to get feedback from other users. Im sure you know you can let it run unloaded and the reading will keep going.

Well, I crank the knob to full and then let it run full for 3-4 seconds. The motor checker gradually increase the motors speed even when you crank the knob. I think either technique will suffice, as long as you let the motor "settle in". Then take your readings from that.
