That's an HPI RS4 3 evo+, and I strongly advise you get a reasonable .12ci engine (yes, these are generally faster than the larger .18ci 'outlaw' engines, but less torquey, call it a peculiarity of the hobby, due to the fact that race rules stipulate .12 only, so they are the most evolved size) with a sealed backplate and a cheap starter box. The main problem with pullstarts apart from their inherent weakness, is that they rely on one way bearings, which get full of fuel and slip, not to mention compromise the seal on the back of the engine. These problems are also common to rotostarts. By far the best way to start a model nitro engine is using a starter box. The initial investment puts many people off, but especially if you get a universal type one, it can also be used for any other nitro model you buy down the line, so should be considered a long term investment.
