Default Newbie RC User - Just Bought a HoBao Hyper 7 as a starter car

I have the one with the .21 engine rather than the mac.28 that I believe is now available, how much faster would that engine have been? I'm sure I'll be more than happy either way because as I understand it the basic .21 engine car is more than enough for a first time car.

I'm almost setup ready to start bedding in the engine but the glow plug I have (a fastrax platinum number 4 medium hot) seems to be the wrong gauge and won't screw in to the engine. Is it the wrong sort? Do need a turbo plug as the Hyper 21 is a turbo engine?

If anyone could also run me through how to setup suspension spacers (is it as simple as compressing the springs by hand and sliding them in?) then that would be really useful, as well as any other things I should know. I'm fairly comfortable with the bedding in procedure because I've read the manufacturers inuctions as well as watched a few videos and had a fairly detailed conversation with the people I bought the car from.

I can't wait to get going with this beast!

The Fastrax Platinum #4 is a turbo plug, so yes, you need a turbo plug. The size and thread is different between standard and turbo plugs. They are not interchangeable.

Buggies and truggies are not all that fast typically. If you can get 40mph from one, you’re doing pretty darn good. They are single speed affairs, so a hotter engine will garner more speed. However, buggies and truggies are not the usual suspects for speed running due to the limited gearing and single speed setup. A stock RTR .28 will get to speed quicker and may give a little better top speed due to increased engine torque, but overall speed won’t improve much.
