標題: 7.5同st一問~
呢兩部車 都係1:8 不過7.5就21級 st 就28級 其實 2部車既車速差得遠唔遠呢?????
會唔會 7.5比st快呢??? 佢地齒比係咪差唔多呢???反應邊部會好d呢?????
如果7.5 落 hn 果部1:8 turggy 果隻大令呔 得唔得呢???會唔會傷偈 冇咁好力????

The 7.5 and Inferno ST are very different interms of what you asked.  The 7.5 is a buggy and the ST is a truggy.  Gear ratio are very different due to the size of the wheels.  The ST has a longer chassis with longer arms.  

Interms of speed, they should be very similar (The buggy should be “alittle” faster).  The .28 engine has more torque for sure, but due to the weight and size of the car, it’s slower.  An example would be a good .21 engine can be way faster then a .28 engine.  The bigger displacement is usually torque related and not speed related (RAW power!!)

HN wheels on the 7. WILL fit with the proper adapters, but you’ll probably kill the engine in no time as the gear ratio won’t be able to handle the load.  By the way, the HN truggy wheels has a 28mm offset, so you should use ZERO offset wheels if you convert the buggy to truggy.

If you want buggy speed with truggy size, you can upgrade the engine on the ST to a more powerful engine (RB, STS, Picco…etc etc).  

Here are the info for both the 7.5 and ST.
