hi guys , I am having some major issues with my hyper st ,

the first problem is that when i am turning into corners there isnt to much turning the front end just slides , Is this something to do with my shocks / springs ? Its not my tyres and im not going 40 mph into corners exspecting it to grip. I am using a futuba 3050 servo .

The second is that the arms actually keep undoing , I have used loktite and they still kept undoing so know i have put longer bolts in them and they seem to have held around the track .... has any one else hade theis problem ?

And the final problem is to do with my engine ..... Its a go 21 5port and in the race i was running it rich as it was only on its 8th tank .... But all of a sudden it leaned it self of and by the time i got to the pitlanes it was reading 378 degrees and the colour of the head and pipe had changed ..... Why did it all of a sudden lean it self off ? any ideas?
