Hi,
one of the chaps at the club had a problem with the cheap nosram, kept cutting out mid race. He could have had a dud of course....
if it were me i would get the 120A hobbywing, supposed to be good for modified and £75 delivered

you could probably get a second hand 13.5T motor for your excess £25
Or i could probably be persuaded by this combo, same speedo as above, just half the fets..... £98 delivered

Of course overseas ordering and running the import gauntlet may not be your thing......
