Looks like a minor defect in the mold. Doesn't appear to be anything to worry about.

I am new to Nitro modelling and obtained a 1/8th scale car from a friend.
I have had some issues with the old model and patched and fixed it up to a good working condition with a few replacement parts. Unfortunately the radio equipment was not the newest and have had to replace one of the servos simply due to the state of the wires causing interferance.
To cut a long story short, I had it out on the road today for a test run and had it running very nicely... that was until the crystal decided to jump out of the receiver and the car went careering towards a small embankment where it flipped on its side which threw the throttle into full and sent it into a wall. By the time I got to it the engine blew the piston into a 100 peices.
The engine is obviously a NovaRossi but the actual type and product code I don't know. It has NOVA up one side and 2000 up the other of the engine casing and also has 3.5, which I am presuming is the CC but other than that I have no idea.
I would post images but too new
but I hope you can help and if you can advise on the what engine this is and the best course of action to fix and whether this is salvagable and is it worthwhile fixing and finally, where to go for the parts.
Thanks all!

if your piston smashed into little pieces, you be looking at a rod, bearings, liner piston and possibly a head button.

If this all is true then do not bother, get a new engine, impossible to get it fixed or somewhere on Ebay you must find something.
If the sleeve is 19.5mm in diameter you probebly can fit a new P/S set but then you have a problem finding the rod. For under the 200 dollar you will find a N21-5T which is a good engine for fun.

If the battery fails the rubber bands will pull the throttle closed. If you loose the radio connection and the battery is not dead, the fail safe will shut the throttle closed whe set properly. The rubber bands need to be strong enough to overcome the servo (coreless servos have much less friction and usually smoother gear train). Brushless are the best put pricey.

Thanks folks, that was my thinking too that it was going to be a right-off as far as the engine is concerned.
The car itself has a few broken areas around the suspention and although it works it is taking time to check it and tighten it all up on each run.
Can you recommend a good 1/8th scale car to start with that is not too pricey and is in kit form for me to build myself as I like to know how it all goes together, get a better understanding of it to diagnose any problems.
I was stupid and hasty as I had every intention of getting a failsafe, just never got round to it. Lesson learned and an expensive one at that! I was told that the engine was a good one and retailed for about £400 which was why I was enquiring about fixing it.
@Roelof - The colling head is purple and an 8 port sleeve so I will not bother fixing it and as Pattojnr mentioned, it will be safer just to get a new one anyway.
Again thanks to all that replied and I will await replies as to a good starting kit.
