On my first ever nitro rc car (HPI Bullet ST 3.0) and using Optifuel RTR 20% and it is smokey. I think once i've got through this bottle of fuel, i'll change to the 'Race' version instead.

I'm also interested in this. Usally only lasts for about 5 minutes on a full tank.

Hump pack charger was faulty, so it wasn't fully charging the battery. Replaced for free.

The issue is sorted now guys. Thanks for the input.

That's good to hear!

Well i guess that depends on each person and how they drive it. I've tested it again with new AA's in the battery holder and it runs fine. Had a volt meter on the new hump pack after 24 hours of charging and it reads 4.5v and the charger light doesn't light up any more, so i think it's faulty. Got a replacement on the way.

I'll stick the hump pack on charge for a bit longer and see if that sorts it

Tried Modelsport but they dont seem to want anything to do with it. Receiver pack was brand new a few days ago and charged for 16 hours.

15175 should be the right part number mate.

I can set it to idle without moving yes. Also noticed that when the throttle servo moves, the steering servo twitches. Which makes me think it's an electronic issue.

It's virtually brand new, bought it a few weeks ago. This is the 4th time I've come to use it.

I have new batteries in both the transmitter and the receiver though...

Just an update on this, put new batteries in the Tx and a brand new hump pack battery in the RX and still having a weird problem. Basically I tested that the power was working by holding full brake and the servo would go to brake then back to neutral then back to brake in a repeating fashion. It also plays up on full throttle and and steering. Anyone got a clue what is happening. Obviously batteries are ruled out, is it a dodgey receiver or transmitter. Would re binding the pair possibly work?

Yeah, seen that just. Thanks.

Yeah it's a 4 AA holder. A 3+2 hump pack should fit i think.
