Default NEW EF-1 MOTOR APPROVED

Guys,

Please use this post as notice to inform you that the NMPRA has approved the following motor for use in EF-1 contests:

Great Planes Rimfire EF1 Race 35-45-1250kV Outrunner BL

These motors will be listed on the Tower website starting later today (5/1/13). The rules will be updated later this year and currently do not reflect this change. Having said that, this notice shows that the NMPRA approved this motor and that it is legal for use in EF-1 contests.

Regards,

Dan Kane

Hi,

Can't find any specs on it yet at Great Planes or Tower.

Would you mind posting a few of the one you have like length from back to front of housing, diameter and weight?

Thanks,
Joe DeLateur.
