WHICH ONE SHOULD HE GET...???????? exactly.. what i said,, the one with the highest kv..
not knowing what these specs were before.. i did know that the larger permax motors offered a lower kv rating with much more power.. now seeing these specs i would say to scratch this idea and find a different motor.. the kv is way too low.. motors have tons of power but you would never be able to gear it to get the speed needed..
you might be able to gear it at 24/41 but im not sure what kinds of speeds you will get.. if nothing else.. the car will run very cool.. and you will have a very long runtime.. and you might want a 3s lipo to make up for speeds lost.. do to motor kv..
you can use this to calculate axle speed..

B TW... not everyone runs on a 18th scale track,, and for those that dont.. not all them even run on a track,,
by now ppl know that i DO NOT RUN ON A 18TH SCALE CARPET TRACK.. from videos and reviews i have done.. those that have read would know.. i only run on large 10th and 8th scale tracks and all my reviews are done according to these tracks and surfaces..
never claimed to run on a 18th scale track,, nor do i try to push the 1105/1.5y on those that are... now the 1105/2y or 1105/2.5y would be great and more ideal.. and i have tried telling others to get those motors instead.. find a new argument please.. this one is getting old.. its the same one in every other forum you post in.
