Before i buy this new i always look for cheap second hand Bronto but most saler sale Rm500 to Rm600 due to up grade parts. After buying, go back and study the weeknest on this car. I found out few
1. The shock tower is soft and also all the lower arm.
2. The dog bone too many free play. Thare is no rubber o ring to reduse the knocking sound.
3. The wheel hub using plastic if tighten the wheel hard the wheel will not turn.
4. The front lower arm lhs and rhs too many freeplay.
5. The main chassis look like soft plastic , when tighten the screw hard the will a deap press mark on the plastic.
6. No ball bearing use in wheels. Only front and rear gear box.
7. The body hole not aline for back hole.
8. There is no hand grip to carry the truck, must carry the truck on the front or rear bumper.
9. The main gear is plastic, i heard from most player it eazy worn off.
10. The instruction manual not very detail.
11. The center shaft also didn't add a rubber at each end so knocking sound.

Below is after looking into some problem i star to remodified, ractified and change some option parts. The gear box i remove and add more grease, their grease become harden.This model are RTR, the instruction did't show parts assembly only over view . I slowly dismental some parts and study it. Not all parts i will change to aluminium, if every parts is alum when involve in jumping or over turn the parts can break eazy. Some parts need maintain plastick like suspention arm so it can absorbe the impack by twisting the plastick parts. For my truck i use blue and black part .
 |
| The ori shock tower is too soft. But the best parts is front and rear same. |
 |
| The drive gear plastick to hard metal. Many say it worn off eazy. I thing because they change to more power Battery, Motor and ESC. |
 |
| Alum steering arm. With spring that can handle the impack will not damage the steering servo |
 |
| The is the wheel spacer for 1/10. Ofter fix can become wider like truggy 29mm long. |
 |
| The short alum wheel hex, stand by if i make it short wheels |
 |
| All the option parts i first change. |
 |
| New alum shock |
 |
| Remove front and rear complete axle. Same as hsp buggy, add grease into the gearbox. At same time i study the inside parts. |
 |
| Change the metal gear and i add some greese and cover. Some they didn't use cover to protect sand going in. |
 |
| The alum steering and change coper bushing to ball bearing. |
 |
| Add the long wheel spacer. |
 |
| It 3.9 mm long |
 |
| more wider look like truggy |
 |
| closer view |
 |
| Change all the wheel bearing. |
 |
| I modified a cover at front bumper. Some time when i put in the body cover i miss fix, back and rear because the front and rear bumper and tower is same, need to look at the steering location. So to solve this problem i add a cover from HPI 1/8 buggy. |
 |
| Front look |
 |
| Bottom with one screw need to change nut and bowl. |
 |
| Change to brush 23T motor. My self never use brushlesh motor before. |
 |
| Add a 6 V low battery checker if i use lipo battery |
 |
| The ESC conector change to D plug |
 |
| Add a cooling fan at ESC |
 |
| Modified a handle bar so can carry the truck eazy. Using bar from Thunder Tiger TS4 |
 |
| Hold by stoper bracket both side |
 |
| The clip secure with 1 line |
 |
| Add a alum wing at back |
 |
| Side view |
 |
| Back view |
 |
| On the body roof, i add a steering bar so that it like bar to carry the car around. But when look it like a roof rag bar. |
Make a decision want to change all parts to aluminium that recomended from HSP. Not to drive fast just to show what the difference. I have another 2 secondhand units brontosaurus that not fully aluminium can use for run/jump. Colour all blue.

| Front |
 |
| Rear |
After install new parts last do wheel alaiment, only camber can be adjust front and rear. Toe only front, but the rules too short, so just adjust on the turn buckle both measure to same length and the wheel should toe in 1 or 2 degree.
 |
| Front adjustment only camber toe the rules too short. |
Change the servo from 3.4kg Hsp E6001 to 9kg MG996R.
 |
| Original from HSP 6kg. |

Make decision to change the front and rear axle mounting from plastic to aluminium. The side mounting for holding the pin easily break. If break i need to open every component especially rear gear box, so if change to aluminium only the plastic suspension arm break easily to remove. Parts reach on 7/6/2020 from china buy for Rm23.
