Hi guys,

First post and new to this RC hobby and new to this forum
too so please be gentle lol....

A friend and I (were both newbies with nitro RC)we just bought a new RC truggy
mine is a Swift PRO 1/8 RTR and he got a HSP Atomic Warhead 1/10. RTR too

We did a break in last night and everything was fine with the Swift PRO
fire up the engine...let it runs idle for 5 min ...
then run it on the backyard..tuned the HSN first then the LSN....leaning both gradually
runs smooth.and I'm very pleased how this truggy performs so far..

So the problem is with the HSP Atomic Problem eerrr Warhead truggy
Its hard to start at first ...but finally got it started....after a few yanks

the problem is it never idles and continue reving itself without any inputs from
the radio controller....its not just revving up but extremely revving till its like
trying to reach full throttle..[:@] what the heck !!! so we try to stop the engine by
closing the muffler with thumb..but engine never came to a halt...

What needs to be fixed? HSN? LSN? had no idea..need help big time!

Thanks in advance guys,
monnette
