doesn't really matter. doesn't affect it. i've done it for years and not 1 problem. people always told me to use plastic over metal for prying and scraping but nah metal always better. there are precautions but yes metal same thing
JQRacing one of RCGP's works teams has recently made a video about engine tuning. Check it out ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zLqwj41Q2YQ.html
yes per cubic inch or micro liter, for the application of small liteweight vehicles yes it is. but not if you mounted 100 of them into a f1 car. then torque and fuel would be a problem. but i like your front page to promote rc racing. 2 strokes are still today the most power to weight ratio, but the usa government screwed us all because they want the wildlife to breathe better so most 2strokes are banned from being produced. just look at power ratios in the year 99 or 2000 liquid cooled cr kx yz rm 125cc motorcross, and they weighed half as much as 2019. the rc car industry is lucky they havent banned there engines and fuel.
@jon gone gone Max Power engines go up to 2.95hp in their OnRoad configuration (40,200rpm). OS engines top at 2.65hp OnRoad and 2.55hp OffRoad. All 3,5cc. Novarossi Mephisto and Toro Nero also 2.7hp. If you convert those specs to real sized engines you get around 750/800hp per litre, very close to 1050hp/L of Top Fuel dragsters. In comparison modern F1 has 500hp/L for the I.C.E.. Back in the 80's, a qualifying engine had a power output of up to 1500hp (BMW M12/13 engine, also know as "Megatron") from a 1.5L inline4, so 1000hp/L, but it lasted only 4 or 5 laps before literally melting the head gasket or blowing up the turbo/engine head. So yeah, those tiny RC engines are pretty impressive and incredibly reliable considering they can last up to 50-70L of burnt fuel before needing main parts replacement like piston head, crankshaft and cilinder port gasket.
@@jamarcus_OG My first RC engine was a OS Max 20 in 1973. It was a cross-flow design with a baffle on one side of the piston and had one ring. It ran fine on my Graupner "Taxi" trainer. I now am studying all things two stroke and I came upon an engine test of this old engine. It's power output with muffler was 0.27 hp at 13000 rpm. Now, there are 3.5 cc engines with ten times the power! Amazing. How much more will we be able to get out of these simple engines?
@@christopherknee5756 As Mario stated in the video, they're already at their full potential. There's nothing you can do to get them more powerful besides finding a way to get more air into them which isn't possible given their scale.
