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.
-
I've got a hump pack fitted as well now makes a world of difference when turning at speed. More power to the servos
That's good to hear!
-
It could be ur servo the stock ones are no good I killed both stock servo's within half ahour after useing a hump pack, I would get high torque servo as the stock ones are no good and not powerful anuff especially for the steering
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.
-
OK.
I'll get a rechargeable pack, any you recommend that will fit in the weather sealed unit of the Bullet ST?
-
I'd say less than 10mins per tank, more like 5.
-
Yeah the 4 AA's
It's only been ran for about 10 tanks of fuel, wouldn't have thought the batteries would be dieing yet.
I'll get a rechargeable pack though.
I'm going to check the fail safe too and set it again if need be.
-
Using the batteries that came with the RTR kit.
The manual says the fail safe is setup to full brake from factory.
-
All batteries are brand new.
Fail safe was working when i first used it as i tested it by pulling full throttle on the radio and then switching the radio off and the servo went back to neutral.
Brakes are working perfectly.
Only thing i can think of is interference, but surely that should be pretty rare...
-
Bought a HPI Bullet ST 3.0 last weekend from Modelsport.
Been running it in the past few days.
Took it to a big unused car park today and something weird has happened...
It took off full throttle into a kerb and smashed the front up.
It did this all on it's own with absolutely zero input from me.
I applied the brake and it did nothing, i then switched the radio off thinking the fail safe would kill the throttle and that didn't do anything either.
What has happened??
-
replaced the fuel tubing and moded the drive shafts today then took her for a proper run. she is awesome!!! never going back to electric xD
only thing Is, I tried to tune her but didn't really know what I was doing haha.
the engine kept cutting out every time a used the brakes? what do I do to stop that??
I don't think il need a wheelie bar either as it rarely wheelied as it doesn't have the acceleration of an electric, but definitely has loads of top end!
will it need another tune when a different number glow plug is used?
If it died when brakes were applied, then you need to turn the idle screw clockwise 1/8th of a turn until it no longer cuts out when braking.

Not literally @super sharp shooter

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.
