I recently got the motor off of ebay for $150 the motor uses a standard plug fires on the first try, but due to the weather I'm stuck just eyeing the breast. I have the motor in a Serpent excel MK2, that I 'm testing the jump from 1/10 scale " The Kyosho V one RR Evo to an 1/8 scale is an interesting one. The motor seem to be a breast, but only true testing will tell..... Oh Ya the web site is all in Japanese, but there is a English version being worked on. The thing want's to look like a Fantom Motor, but the head is in silver not red.......
