oh well, ive had my fair-share experience with nitrous RC cars.
my ex gf bought me a brand new thunder tiger ts4n 1:12.
only lasted me about a week and out of that i played with the car twice.
me n my mate took it to tesco car park on a sunday afternoon to test it, we were right on the far side of the car park.
as the car got near the half-way mark, it just started to accelerate more and more i tried to bring the car to a halt, it didnt work. tried steering the car it didnt work. in the end, the car just carried on accelerating and went right to the other side of the car park and whacked the kerb head on, resulting in all wheels falling off, a super bent chasis,all the suspension broken.
as i got to the scene few mins later, u cud still hear the engine roaring louder and louder, we thought it wer gonna blow up.
eventually engine stopped and the car park was full of smoke.
i took the remains to a local hobby shop, who made me an offer of £150 for the exact same car but i just never went back to get it.
if i cud afford it, i wudnt mind actually buying 1 but lasering and deejaying are 2 of the most expensive hobbies i have ever come across.
