HSP Breaker (Redcat Sandstorm)

Post by Sixtys Guy » Thu Aug 13, 2015 5:37 am

I just had delivered today a HSP Breaker. This looks to be the same as the Redcat Sandstorm. I should know better than to buy a cheap RC car, especially after my GP experience..... but I bought one anyway! I have been looking at these on Ebay for ages. I love the scale look. I would love an Axial Yeti, but I'm hoping I can have some fun with this much cheaper buggy. I have a few plans for it (of course), but I will post up pics as I make the mods.

I ony got to run it on the concrete workshop floor at work - it's great at drifting! It is pretty slow. Apparently the motor is a 21T 550 Motor, which theoretically would be slightly faster than a stock silver can. I will replace the motor with a 15T Firebolt that I have spare.

And just because I can't contain myself from letting my plans out of the bag......

They are Crawler King wheels and tyres. I was planning on using Wraith wheels and tyres, but these just fit better.

Stock gear ratio is 8.3:1, too high for these tyres. The stock pinion is 23T, and to get to what I see as a decent low ratio of around 16:1, I will need a 12T pinion. I doubt if such small a pinion will fit, but I will pull it apart on the weekend to see.

I think you might be better off leaving the stock motor in place with those.

.... I also suspect.... that thing might live up to it's name.... :shock: :lol: :mrgreen:
Sorry, could not resist.... I do hope I am wrong, as that looks like a fun buggy.

Lol good call :wink:

To be honest I'm not expecting much from this. It was only $148aud (about $110usd). I'm wishing I bought the brushless version though. For an extra $85 I could have got a 3300kv brushless motor, hobby wing esc, steel spur gear and bearings. I didn't realise when I bought this that it only has brass bushings,

I don't think the gearing will work with these tyres so I may end up going with some smaller tyres.

I've been having a blast with the 'Breaker'! Happy to report no breakage either, aside from a burnt out motor, but that is probably to be expected from a chinese RC. The car has taken it's fair share of tumbles and I'm really impressed with how robust it has been. These HSP models have a fairly average reputation on the net, but I couldn't be happier. It has been exactly what I wanted it to be - a cheap version of an Axial Yeti.

Mods so far;
- SCT wheels/tyres off Ebay. They look a lot like 1:1 BFG KM2 tyres
- Thicker 12mm hexes to clear the new wheels from the tie rods
- Hobbyfans 3300kv brushless motor off ebay ($15Aud = $11Usd)
- Hobbyking 60 amp esc that I already had
- changed the pinion from 23T to 17T which changes the gear ratio from 8.1:1 to 11:1
- I don't run the front part of the body, this is to get more airflow to the electrics

The motor is a beast! I think I will order some more for one of my Clods. On the local MTB training track, they tyres don't grip so well. I'll have to see what SCT tyres work on dusty, dried clay.

Hot bodies (a division of HPI) makes a tire called "BEAMS", get them in the softest compound.
I race on hard clay..... :mrgreen:

Thanks Andy!

These ones? http://www3.towerhobbies.com/cgi-bin/wt ... LXABMA&P=7

I would have thought they would need bigger tread? Are all SCT wheels the same size.... inner and outer diameter different?

yes, those are the ones.
Yes, SC is a size all it's own, there are some variations in outer diameter and width, but wheel sizes are all 3" inner and 2.2 outer.

Be aware that they do NOT come with foams.

What I would do is take what you have now, and take scissors to the tread face so you can get the foams out intact.....
Then pop what left in the oven and get the rest of the rubber off.... then either use a dremel or acetone to clean up the wheel beads.

Traxxas foams fit pretty good with those tires. They do wear out after a while though (the foams).

If that's an issue, order the red AKA foams shown on that page, as well as some wheels.

Thanks Andy. I've done some research and I really like the look of the Proline Badlands. They look like they would dig in and give plenty of traction.....

Yes, it's the same vehicle. Good think is that parts are cheap as chips and easy to find on eBay.

Lol, haven't tried it on 3S! I did briefly install a 4400kv motor, but it was too much.

I saw a Yeti in person for the first time today at the LHS, it is huge compared to this. Looking at specs, this is more like the size of an Axial EXO or Vaterra Twin Hammers.

I definitely should have gone with brushless version, as I have now made the mods that come stock with that one. I think they larger tyres are also a must. If nothing else, they stop the chassis from hitting the ground at full compression.
