There seems to be a lot of people mentioning that they are running this that and the other set up with regards to brushless/motor/lipo/nimh. With nimh a little harder to get a hold of good quality 'matched packs' these days, i feel the obvious route is lipo with regards to how we power the cars.
Now clearly there is a difference in voltage between the two and there is also a difference in performance.
I raced today for the first time in around a year, i started the day off with mardave brushless esc and motor with an intellect 5000mah 1s lipo. I was running 48 dp with a 75t spur and 28t pinion, a little taller than i would normally run at the track i use to/made a return race at, (wirral mcc, Neston) i did this to try and compensate for the lower voltage. The car was certainly not that far off the pace (small track granted), but it got me thinking. Rather than everyone, or at least a large amount of people going out and buying the e z run set up or whatever it is, would it not be more wise to simply try and find a slightly larger (not 540 13.5t etc) motor to try and compensate for the lower the voltage, not sure of the specs of the currently supplied motor with the mtroniks/mardave brushless set up, but i think that spending say (as a gauge) £25 max for a new motor so we can run the 1s lipo wouldnt be too bad. as i say, i havent raced for a while so maybe im way wide of the mark here. (Ps. I'm not wonderful at getting my thoughts down but i'm sure you get my drift)
Your thoughts please......:confused:

we are going through the same thought at the moment at our club we run the g2 motors or the hpi 20 i myself are going through the same rigmarole of trying to find some matched cells there doesn't seem to be any around and when you do find some they are silly money lipo's are much cheaper but when you maybe the only one that is running lipo then you wont be able to keep up with nimh cells. it will be only a matter of time before nimh's are gone or will it?

i just toying with the notion of coming back from racing after a 18 month lay off.now after doing 10th offroad with brushless and lipo and now going back to mardave and gee's what a pain charging cells are pls oh pls everyone go lipo then its the same for everyone!

basically brushed and brushless will be the same speed ,ie nimh and a brushed motor or lipo and 13.5t brushless ,the confusion comes when u mention the mardave brushless system, this looks like it will run in a different class.Hinkleys rules seem to be the best for this the nimh brushless will have weight added to slow them down and lipos none for an intrim period while everybody goes over to lipos ,these seem fair and bring the classes back to 2 again,the only issue i have is £70 for a motor when there are so many manufactures, 1/12th are developing motors to take advantage of the amp side of the lipos so sooner or later there will be a faster motor out,another £70 then theres short stack 3 and 4 pole different magnets,if someone could convince mardave to make a 13.5t for a fixed price then theres no issues about whos got the best motor ,hes doin them for £40 at the moment and mines lasted 2 years ,i not gettin into a rat race of buying motors time and time again its not the mardave way ,and how do u say to a kid its £70 for a motor if u want to win plus the cost of the car speedo and bits,mardave wont be a starter class and numbers will decline,i hpoe the proposed comittee doesnt just caiter for itself,hinkley seems to be the only ones with the ideas ,maybe they should start there own committee to run for the brca

Well this is an old Video of me running a 1s LiPo and 13.5 at MERCC club just to give you an idea of a Small track . .

I will Get another one done on Tuesday at Ardent a big track for those of you that dont know it
