Worst car to work on Worst car to work on. Every bolts are overtightened, and round off SUPER easily as if they are made from butter. I was trying to install few upgrades for the RS4 Sport 3 straight out of the box but eventually threw out the chassis before even I drove the car. So I gave another try with the same chassis, spending same amount of money but failed again. Diff case screws rounded off when I was trying to install spools, carbon shock towers did not even fit properly (you have to force it into place), and carbon underbody driveshaft cover is totally out of size. I was getting fed up with the screws rounding off. Out of the box, it looks promising, but if you are trying to upgrade the chassis, spend that money somewhere else. You will not even be able to install them.

Don't Buy HPI if you care about any support or warranty, I bought a HPI Sport 3 Drift, wrong parts inside, HPI telling me lies to avoid fixing problem OK, so i bought a HPI sport 3 drift (Brand New Sealed). I went to my friends house to adjust the gear mesh as a pre-caution not to damage vehicle internals. I noticed that my ESC was different to my friends (Bought the same rc i did). I messaged the seller on ebay who said the car had the correct parts and if i didn't want the car to call the distributor, which i did. The distributor was very helpful. He spoke to HPI who said the first batch of cars came with that ESC (SC-15WP which is from older model) and that it should have that in the manual i get with the car. I checked the manual and the ESC is suppose to be a SC-3SWP2 which is the same model that is listed on the HPI website. This will be the last HPI product i will ever buy as there is NO Support at all even when bought new.

Do not buy HPI, it should be their catchphrase! I purchased an HPI Trophy 4.6 over a year ago and I still cannot use it. It constantly fails to run or even pull away without stalling (I've run it in by the book), cheap quality parts and poor build quality from this company. I also have a 10 year old HPI nitro car and never had any issues from day one. Its no wonder they had so many owners with such poor products.

£359 bullet mt 3.0 nitro Brought a £359 bullet mt 3.0 nitro Plastic cheap quality parts, clutch issues, asked for support, basically tuff, it’s a hobby sort yourself. New I should of purchased a Hoboa as everyone told me HPI was cheap plastic models that spend more time in repair…….. Never again will I buy there inferior quality products.

Hpi quality isn’t what it use to be I’ve been racing nitro rc for more than 20 years now. I’m on my third savage 1/8 truck. The first two were absolutely rock solid but can’t say the same for my latest purchase. Steering servo was severely underpowered for the tire size and needed to be upgraded to a savox....Add another $80 straight out of the box. Got about 10 hours of run time then the roto start failed. Spoke with an authorized dealer and was told Hpi isn’t the same quality they use to be and they aren’t charging less for their products. Too bad management is going towards cheap parts for greater profits.
