Cobi Blocks Small Army Electronic Series Challenger I Infrared Tank Product Review
quite the product name... also sorry for the poor quality main pic, it was the best one i could find...
About this creation


i am writing this quite late in the evening, so bare with me here, thanks

*end disclaimer*

ok, as you may or may not have known, this is a RC type of vehicle...
which when made out of a "Lego Product" one would expect a high price, well, your wrong

its not Lego, but one of the very good knock off brands, Cobi, a very very good brand i might add, and as such i got this for 100$ USD, not bad...

the one i have is actually the second, the first was heavily damaged on its way to the proving grounds, and had to be sent back before the prototype could undertake trails.
in other words, it was broke while shipping... i could tell it was while shipping because its packaging, which i will get to, had a massive dent in its corner, the strongest portion of the packaging

being that it was a shipping error, you can still count on me to buy Cobi products, good toys are good, nothing else to it

now on to said product...


the outside, or packaging, is a very nice tin metal box, with quality printing on it, i can only assume to properly protect the product during shipping, except under extreme cases, such as mentioned above, the top is not connected to the bottom, except for sealing tape.

*INSIDE, the goods*

inside you get an assortment of 1 stray plate, used in the 1st step, and bags upon bags of pieces, you get a manual *breaking 4th wall, duh of course they would give you a manual, but ive seen many set reviews of even Legos kits, where people ask "is there a manual?"... *facepalm** as well as a box which further protects the IR pieces and wires.

*INSIDE THE INSIDE, the IR pieces*

in here you will find a bag of wires, with snap connectors, and the following

1- Brain/Distributor Brick, connects all the wires much like an NXT Mindstorms brain brick
1- ON/OFF brick, has the switch, as well as the light to indicate on/off
1- IR Receiver, receives the signal from the below mentioned remote
1- Battery Box, holds 4 AA batteries (not included)
1- Turret Traverse Motor, traverses the turret 360 left and right
1- IR Remote, sends commands to the tank via IR signals (2 AAA batteries not included)
2- Headlight Bricks, lights your path at night
2- Taillight Bricks, lights the rear of your tank, at night
2- IR RC Motors, propels the tank forwards and backwards, as well as conducts steering


the build is straight forward enough, even for me having not experience what so ever in "Lego RC", and then going straight to an RC tank... however, somethings of note

- i would highly recommend getting the wires placed right the first try, they do not look strong enough to be removed once placed, without special tools to keep them intact, indeed it is a tight fit...

- you first place the motors for hull movement, followed by IR Brain, IR receiver/ON/OFF switch (same step), then battery box. i would at this stage place batteries in both the Bat.Box, and Remote and test the motors for functionality, if you feel product may have been damaged in shipping

- i know when your building it, it looks as though the wires wont fit, indeed there are some quite tight connections, much tighter then id prefer, but the wires do, in the end fit quite nicely in the tank, it gets neater as you go

- the gun is not remotely elevated/depressed, but by hand, which i dont think is a bad thing, and its mount is solid to insure security during play


Length 34cm
Width 15cm
Hight (to top of turret) 12cm
Hight (full build) 19cm
Ground Clearance 0.6cm (not alot i know)

*FEATURES, the fun stuff...*

*IR Features*

- 360 rotating turret
- 3 speeds of foward/reverse movement
- 2 levels of brightness for head/tailights

*Dummy features*

- hand elevated/depressed gun, with stable mount
- 2 opening/closing turret hatches
- 1 rotating and elevating/depressing turret heavy machine gun
- 1 opening hull drivers hatch
- 2 opening engine hatches
- 2 opening toolboxs, for storing the included mini mega fig tools
- 1 per side of lifting sideskirts, to access the suspension
- opening lower front plate (imagine its for the transmission or something)


- 2 of their patented "Mini-Mega-Figs"
- 2 helmets for said figs
- 2 vests for above figs
- 2 handheld weapons, a pistol, and a machine gun for said figs
- 4 tools, a hammer, screwdriver, bolt cutters, and a wrench (may possibly vary)


well, here's what your here for, the specs, the info, the whatever, its the need to know bits of detail...

- Turret does rotate round and round and round, at a decent pace
- The Lights are bright, you get a bright level, then a super bright level, good for outdoor night time play
- Speed you get the same 3 level of speed forwards, and reverse

Slow Crawl - really and i mean REALLY slow
Less Slow - a decent pace, this is the minimum speed that allows for turning while moving forwards/backwards
Fast - this speed, while also slow, is much faster compared to the others

- Neutral Steering, yes you can pivot in place

you can have the lights on full, travel at full speed, and traversing the turret, while also steering left/right, the IR Brain does not get overloaded


ah yes the thing that works with that other thing to do the stuff that you paid for

these remotes are multichannel, meaning you can run all 4 C.B.S.A.E.S (Cobi Blocks Small Army Electronic Series) kits at the same time, or run all 4 at different times, on 1 remote, to program it, 1st turn on the tank, then press and hold the power button on the remote until the little light on the top left no longer blinks, but stays solid yellow, then while continuing to press down the power button, move the joystick to the left, the lights on the tank should flash, indicating a successful reprogram/first program.

pressing up on the joystick will start the tank forward at the slowest speed, press it again to move to the next, and yet again to reach to highest speed, much like shifting gears, press down on the joystick in the same manner for reverse. OR you can hold it forward, and it will automatically move through the speeds to the last one, pressing down in the same manner will work the same in reverse

to slow down a speed, move the joystick in the opposite way the tank is moving, so if moving forward at the 3rd speed, press down the transition to the 2nd speed, same way in reverse as well OR you can press the "STOP" button to slow down, hold it to stop

to turn, press left or right at a stationary to start pivoting in the direction indicated,
press so while moving will slow one track in the direction you want to turn

to start the lights press the middle light bulb for the lowest setting, press the left light bulb for the highest, and to stop them, press the right light bulb, with the "X" through the light bulb

to traverse the turret left, or right press the left or right turret button, to stop the turret, press the center turret button with the word "STOP" on it


the tank will continue to move forward/backwards at its last speed indicated by the user, until said user fully stops the tank... caught me off guard and had to keep it from falling off the table...

the turret is the same way, it will spin and spin, until you command it to stop

the lights also work the same way

the only thing that does not work like the above said things is steering, it will steer only as long as you press the joystick in the direction you want

the motors are sealed, and it does not move at a blistering pace, so you can take it outside, quite fun to do in the dark...

the track is very tight when first built, so much so that the tracks will pop at first, i have tried many "Mods" to help ease the tension, but all failed to leave enough to allow the gear to grip the tracks, it functions the same way a Russian T-34 tanks drive gear works, but after a few hours of play it naturally eased up, and now it no longer pops its tracks

one mod i did make however was to the remote, as the joystick is very small, and could allow for unintentional commands, i added 1 1x1 round brick over it, and now its much more

you have an operational range of about 5x5 meters (about 10-12 feet) out side that and the tank can no longer receive commands, so catch up to it!


i use energizer rechargeable batteries, the kit takes the following

4x AA batteries for the tank
2x AAA batteries for the remote

i cant tell you how long they last because i dont know... i got about 2 hours out of them before I gave up and came inside to go to bed... still though 2 hours is a good run considering mine take 5 hours to charge...

thank you for your time, and add me as a fav to see when i post the next review...

Quoting Tommy Styrvoky Would it be possible to reconfigure the hull to different vehicles, or are you stuck with a prefabricated hull? also same with turret, is it only fixed in the center? Would it be possible to put some photos up of the vehicle, does it have a sprung suspension?
Sorry for the late reply, no suspension, the wheels rotate, that's it The Beige Top Hull Piece is a two piece design, forward section, and middle/rear section. This allows you to remove the turret, and hull top for easy access to the batteries. The turret is brick built on top of a large turntable piece with the motor and gear protruding through the top of the hull. this allows for infinite 360 rotation. In short, its nowhere near the complexity of your custom MOC's, and as $100 I wasn't expecting even as many functions as I got. They have re-released the kits for Bluetooth use, I'm not sure if they made any actual changes to the build of the kits themselves, or just RC/IR capabilities...

Quoting Deus "Big D." Otiosus Dude, just no. No. This is a cloner set. No.
while i cannot deny that it is a cloner set, Cobi is the second largest brick maker in europe, obviously behind Lego... show some respect and branch out, youll be surprised at the quality some cloner brands have...
