Curtis,
thanks for an awesome motor, made me post one of the best laps ever, just .05s off the top driver. too bad rain stopped me from posting one of my own. oh well, there's always the next race.

FASTER IS BETTER.

In general, you use 4mm blanks on 10 turns and above.....while using the 5mm on 9 turns and below.....
There is exceptions like 10 turns for 1/12th scale are usually wound on the 5mm blank for additional efficiency (aka more runtime!).....and occasionally you see some 9 turns wound on a 4mm blank.
The 4mm blank is basically the RPM blank and the 5mm blank is basically the torque blank.....which is how trinity labels them...

Hi Ray,
Ok here we go:
Mainly for 12th scale I recommend to use the 5mm blank, as this is the most efficient of the 2 armature. The 5mm blank will suite any type of track and for any condition. HOWEVER, I do use the 4mm blank for 12th scale and quite often, but there are a special set of circumstances: 4mm blanks will run great when used on tracks where the layout is “Point and Shoot” (i.e. lots of 180’s with short shoots between each corner). For this type of track layout the 4mm blank will accelerate harder and have more top end than a 5mm blank, and runtime will not be an issue. But if used on a “Flowing” track layout where you’re using the throttle more to maintain corner speed the RPM arm will run inefficient and you will most defiantly DUMP….So you need to know when to use a 4mm blank and when not too…. Perfect example: Snowbirds the past 2 years, in 2004 we used 4mm blanks in 12th scale as the layout was what I consider to be a point and shoot type track. Tons of RIP and runtime to spare. BUT, in 2005 the layout was open and flowing, a 4mm blank would never work on a layout like that (I did try a 4mm arm in Jeff’s 12th scale and came up short on runtime every time)….
For Sedan pretty much the same is also true: You just need to know when you can use the 4mm blank…. This comes form years of experience….Hope this helps, let me know if you have anymore questions.
Curtis,
