let me start by saying that i spent alot of money buying and trying a lot of big name comercialy available motors and esc combos.Because i live in oc., CAand am close to NOVAK,TRINITY,Assosiated,ORIAN ect. i started out with aGTB witch i already had and an Orian 10.5 .im running an RCM crt .5 so im alittle heavier than your hyper mini, by around 1 lbs 6oz. so the 10.5 worked but wasnt fast enough to race so i got talked into a 4.5 LRP that halled but broke very quickly because it frankly has a weak asembly design.it ran long enough to work out the gearing at 9 or 10 tooth mod 1 and would come off at 160 deg so i cant change the spur '46th' and 4.5 was crazy so i got a Orian 6.5 ant it seemed perfect coming off at 140/150deg and very fast but wile bashing .it went 200deg in two min.all this was on2s 46 th spur 9/10 pinion so i gave up and put an HV 7.5 on 3s 14 to 16 th and itll run all day at 140deg bashing or raceing. for what its worth good luck and dont forget to have fun!
