Ghost Posted January 11, 2012 Share Posted January 11, 2012 The only problem with cheap RC's is that there can be more problems that meet the eye, Good luck though! Quote Link to comment Share on other sites More sharing options...

HATZY Posted January 12, 2012 Share Posted January 12, 2012 a mate i bash with has an mt2 g3.0 and over all its pretty fun, fairly strong and easy to work on. it ate a front dog cup so was rear wheel drive for a while and even after all the abuse its had, its only just broken. snapped front wishbone.

don shaleone Posted January 12, 2012 Author Share Posted January 12, 2012 Im going to have a look whats wrong with it soon, whats the best way to check compression without a proper tester? Quote Link to comment Share on other sites More sharing options...
Rusty1103 Posted January 12, 2012 Share Posted January 12, 2012 take out the engine and hold the flywheel. if it can hold itself upright for a good while then compression should be good if it falls like a brick then it doesnt have good compression Quote Link to comment Share on other sites More sharing options...
don shaleone Posted January 12, 2012 Author Share Posted January 12, 2012 Well I've had it started now, but apparently before the previous owner new it was broke he said he use to use it for 10 mins once its warmed up it would cut out but then start after cooled is that down to compression or just over heating? Btw got the 2.4 system today Quote Link to comment Share on other sites More sharing options...
Rusty1103 Posted January 12, 2012 Share Posted January 12, 2012 that will probably be due to compression. sounds like it is on the way out. as the engine gets hotter the metal expands in turn this will allow air/fuel to go down the side of the piston. have you took an engine that you know doesnt work or arent scarred of damaging to bits? manuals/diagrams are good to get to know the parts of the engine but taking it to bits yourself so you know how it all feels and looks is the best way to find out how it all works. imagine the engine as a syringe where the medicine/drug is the fuel. the plunger is the piston and inside the body of the syringe is the piston liner. if you use the syringe hundreds or thousands of times the plunger and the inside of the body of the syringe will begin to wear away allowing the drug/medicine to come out of where you press down with your thumb.

HATZY Posted January 12, 2012 Share Posted January 12, 2012 my mates was doin that for a while. then he broke the coolin head so i put a force 25 head on it and it stopped Quote Link to comment Share on other sites More sharing options...
don shaleone Posted January 12, 2012 Author Share Posted January 12, 2012 I know 4 stroke engine alot better as Im doing mechanics at college, I understand it might be worn out. I had it idling for a short while earlier and it was smokey as hell just on idle, would that be due to a worn sleeve/piston? Quote Link to comment Share on other sites More sharing options...
Rusty1103 Posted January 13, 2012 Share Posted January 13, 2012 Could be down to a rich Lsn Quote Link to comment Share on other sites More sharing options...
