M3R DIG WHEEL MODIFICATION FIRST RUN
« on: June 22, 2015, 08:53:30 PM »
At Cotswold today.

Perfect lap.
Moto 3                  25.5 sec
Neal  KP14 Stock    25.6 sec
Moto 2                  26.0 sec

First impressions of the Moto 2 mod, you can brake later and accelerate earlier but the corner speed is lower.
There is more to come, with a light battery it stays down hard in a corner, with a heavy one it has to be held down.  The gearing could probably take a bigger pinion. Also the Fork damping needs sorting out.

The fastest time was set with the following settings.
Gearing 70/31. (5.93)
Motor SKYRC  17.5.
ESC Hobbywing EZRUN WP60 (sensorless)
Tyres GRP S1 front and rear no weights.
Battery 6500mAh Hard case.

That's interesting Fred and good to see the like for like times. Handling traits are as you might expect but theory is one thing and actual on track performance another.

How did the two compare in terms of stability and ease of driving - is there much of a difference? I'm thinking in particular as to whether the big back wheel is easier for a beginner?

It would also be interesting to compare the small back wheel with lots of weights (three each side) to the big back wheel?

When's the next test?

M3R used for comparison settings

ESC           Xerun Stock V3.1 (Blinky mode)
Motor      SKYRC 17.5
Gearing    Front 70/33 rear 36/16 (overall 4.77)
Wheels    Front GRP S1 1 weight each side, rear GRP S1 2 weights each side.

The M3R Is set exactly as I like to suit my driving style, the other bike (Shall we call it the M2R) I was having to hold it down so it was a little bit inconsistent but Neal said it looks a lot smoother.

These tests were done with extreme lean angles on a really grippy track.
With less lean angle and slower steering, my opinion it would be better than a M3R for a beginner, but better than anything else???? We need a beginner to try it.

PS Both bikes ran with the Headstock rear in the bottom holes.
