prelude 19: Yup, Pro2 hop-ups can be fitted on the Sport2. Too bad that HPI website is currently down, u can look at the hop-ups and tips they offer for all of their cars. Regarding spur and pinion combos, a simple rule to follow is use a 93teeth (48pitch) spur gear then add 12 to the number of turns of motor ur using. So w/ a 9T motor + 12 = 21 pinion, a 10T motor + 12 = 22 pinion, and so on and so forth. Remember that this is only if ur using a 93T spur gear. Use bearings to make ur car faster due to less friction and proper oil/spring combination for the suspension. Use the best tires, Sorex and Take-Offs. Hope this helps

prelude: yes, all the pro 2 parts can fit on the sport 2. i personally use 64 pitch gears. if you want a good site for set-ups and gearing, u could go to these sites

in the bennett-racing website, there this gear ratio computation chart. when you choose the car for wich youre going to compute the gears, just choose the pro 2 coz it has the same internal drive ratio as the sport 2

in the welcome.to/drdiff site, there are tons of set-ups and tire tips

as for tires, blue is right. Sorex and Take-Offs are the best. Pro-line is pretty good too but they are really expensive

just went to the bennet site. if you want insanely ridicilous top end at the cost of runtime (and maybe your motors endbell ), try using the 106 tooth 64 pitch spur gear and the highest pinion gear u can get. so if you get a 50 tooth pinion, ur Final drive ratio will be a whopping 4.45!!!!! that's pretty hairy for me so i'll leave the speed runs to you!

in sum, get the smallest 64 pitch spur u can get and pair it with the largest 64 pitch pinion u can get! word of warning, a car this fast is extremely hard to slow down!

not really sure with the runtime, but i guess you'll probably get less than 3 minutes max. as for the price, i'm not really sure about the prices coz i live here in the philippines. y dont yu check ehoobies or towerhobbies for the prices on the pinions and spurs. if u do, gop for the robinson racing suprs and pinions, they're pretty good.
