hi Ziggy12345,
It is me Philip, we met at aldershot last year 1/10th national......Welcome abroad to the world of 1/8th....From your driving skill i would suggust a megapicco, they are very good value for money and power ( i used one but never actually own it !!!!).....i have a jp R 01., it is very powerful, but the crankshaft snapped near the top end.....the RB are good engine if you can tune them, i am still running a Rody RB after a year with the same p/s and con rod ( only changed the bearings) ...it is excellent for flowing track,and even guys with jp have problem keeping up at the straight...with good driving skills and setup....POWER is wot u need in 1/8th !!!
