TEST: REMO 1631, 1/16th 390 brushed car

null

INTRODUCTION

Here is the mini-review of a new Brushed Monster Truck brushed RCcar, in 1/16th scale, the REMO 1631. Offered main features are the full metal gear system, the waterproof capacity and generally a more robust car versus the other cheap competitor models (WLtoys A7x9 series for example). Let’s check this bundle

BOX CONTENT

null

+ 1 x REMO 1631 (with a 2S 1500mAh Li-Ion with T-Dean connector)
+ 1 x Transmitter (using 4xAA batteries not included)
+ 1 x Charger
+ 4 x C-clips
+ 1 x Spare main transmission wheel
+ 2 x Allen Keys
+ 1 x Crosstool
+ 3 x Instruction manual (English)

High quality printed diagram… a good thing for the maintenance

OVERVIEW

The general design is a classic Monster truck with relatively large Wheels to increase Off-capacity

-FRONT VIEW
null

For each front/rear side, shocks absorbers are not oïl filled…. and unfortunatly are too much flexible for real offroad rocky conditions with a bouncing effect.

null

At least some metallic dog bones are here

null

For both rear and fond side, a unique U metal bar is here to lock both the shock absorber as well as the suspension arm

null

It should increase the general solidity of the stucture in case of frontal or lateral shocks… That’s a good point

-SIDE VIEW
null

null

Plastic Hexagons are installed on the four wheels

null

and ballbearings are also everywhere

null

-REAR VIEW
null

As for the front part, the U metal bar is also here

null

-UPPER VIEW
null

-BOTTOM VIEW
null

null

IMHO, the weakest element is the jonction between the main plate chassis with the narrow one under the shock/arm parts. In case of high jump,
this section can break

null

-WEIGHT
A total weight close to 900g… a little bit heavy IMHO… there is will be some negative impacts on the top speed and acceleration main probably

null

LiPo

No Lipo but a 2S 1500mAh Li-Ion battery instead

null

No doube a real LiPo can be installed if you want an extra little boost in speed. 3S battery won’t be supported

Disassembling

null

The main shock system in plastic

null

one of the weakest element versus time.

The steering servo

null

No indication about its capacity and no ballhead screws installed too.
BE AWARE, ALL M2 HEXSCREWS CAN BE STRIPPED EASILY WITH THE GIVEN ALLEN KEY. CAN BE A PROBLEM FOR THE CAR MAINTENANCE.
null

The main 3-in-1 board including a mini Power distribution board, the car controller and the builtin Receiver.

null

For the Receiver it’s probably a FlySky model so expect a good radio range despite the fact the antenna is short

The tiny power switch can be easily controlled even if the canopy is installed

null

Motors

A large 390 brushed motor cooled via a heatskink.

null

On of the cooling hole is located bottom and can collect some piece of rock IMHO…..

Transmitter

null

A top buttons permits to set the throttle course in 70/30 or 50/50 configurations. It means for in 70/30 mode, the forward throttle course will represent 70% of the control deviation, 30% for the rear direction. The 50/50 is obviously more adapted for climbing.

null

The radio offers a lot of controls via pots: D/R and tim settings.

null

The Throttle D/R is usefull to reduce the top speed and be more adapted for climbing configuration. In the other by limiting the steering D/R, the car will be more suitable for high speed runs.

null

UNBOXING AND QUICK TESTING

As you see at the demo part, this car is fun and seems robust. With the 900g, as expected top speed are far from the 50km/h but in another hand, the traction is good enough to climb high steepy roads. In offroad conditions, it’s hard also to keep straight lines despite being a 4WD model. Situation is improved on macadam surfaces.

CONCLUSIONS

The Remo 1631 is a good first RTF model with a good radio rig, & metal gear system but as for many other cheap RCcars, the nylon lower plate still represents the weakest element. Anyway, the offroad capacity of the 1631 are here especially on ground surface. With 900g, the top speed don’t reach the promised 50km/h (but > 40 km/h) and the car bounces a lot. If you plan to drive it in rocky/sandy situation, I advise to seal with sillicon the gear top cover box at least.

PROS

+ Full meta gear system
+ Good radio range (> 150m)
+ D/R & Trim radio settings
+ Good offroad wheels
+ Waterproof 3-in-1 board
+ Heatsinks (3-in-1 board & motor)
+ 4WD system
+ Good instruction manual

CONS

– None Oiled shocks
– Shocks too flexible=>bouncing effect
– Poor quality M2 hexscrew (be aware for car maintenance)
– Not a 50km/h car
– Hard to keep straight lines
