History:
I built my first 6x6 1:10 scale R/C model when I was 14 years old and living in Hong Kong. Based on a TAMIYA 4x4 pick up truck and an all new hand made chassis, new rear motor housing body. It had a PTO, fitted with a STD 3 speed gear box, a rear axle control by the PTO gear; 2 sets of free wheel hubs fitted at the front and third axle. Powered by a powerful industrial 12volt motor. However a 6x6 is not like a 4x4, it causes a lot of problems, mainly because the 2nd and 3rd axle have no differential and the 3rd axle and 2nd axle are resisting the steering a little. I also made a 1:8 scale Yankee 3.5cc full time 6x6 model with a Pinzgauer Van body, this also had a lot of problems, because if the suspension is not good, 2 or 3 wheels are always off the ground. The purpose of the 6x6 is to go anywhere, however the 6x6 drive system makes the car difficult to turn well.
The 6x6 also use to much power when driving on a good road. I also have some modern UK made Range Rover 6x6, a 6x6 truck and a 6x6 amphibious, however non were satisfactory. But now I have discovered the JRA Perentie 110 six by six. However even this vehicle has one big problem, the 3 axles are without differential lock.
Australia Army try to test 2 tonnes pay load pinzgauer 6X6 & discover the rear is not big enough, they try to use 110 to build a 2.6 Tonnes pay load strong 6X6 Truck. The spacious Perentie Land Rovers was developed by Jaguar Rover Australia at end of 80's for Autralian Army & one popular model is long range patrol vehicle used by Australian SAS, Commando, Cargo carrier personnel carrier, Repier air defence, ambulance, mobile workshop, recovery vehicle, and a gun tractor (max toning weight for off road 1.5 tonnes, Total 2,6000kg chassis cab +3,000 kg payload +1,5000 kg Towing 7,100 kg!) a heavy duty hot-dip galvanized square section steel tubing as seen here.
Front use heavy duty coil suspension, rear use 2 pair of leaf spring, between 2nd and 3rd axle got a see saw for self aligning. Rear axles carry Salisbury differentials and have a wider track than that of normal Defenders. This steel space frame chassis that is more strong and good than UK moditied 6 wheeler with independent 6 coil chassis a lot. The UK made 6x6 rear 2 axle without a self balance see saw, so without heavy load, one axle will lift when road condition is not good. On the road it is a front and mid axle drive, with open middle diff, same as 110 permanent full time 4x4 system, when off road, The third axle is driven from the transfer case PTO (power take off), a long propeller shaft pass the 2nd axle top direct to the 3rd axle. When locked the middle differential. Not like UK made 6x6 , they use V8 3.9 EFI full time 4x4 running gear modify a rear axle to have another power out put put for 3rd axle, control by a cltuch, but this axle got very big size and the rear propeller shaft pic1and transfer casing very easy broken when the 3rd axle drive. (Because the 2 axle properller shaft need drive both 2nd and 3rd axle at same time). Also not good for off road, the 2nd axle Ground clearance is not height enough, the 3 axle propeller shaft direct to the 2nd axle bottom, this make the Ground clearance very low too. Over 700 perentie 110 6X6 ordered by Australia Army. 110 6X6 got a Thomas T9000M PTO winch, all Axle with Australia made heavy duty haft shaft, heavy duty 4 planetary gear Differential, rear salisoury Axle with 4.7:1 Gear & 4 inch wider than UK salisaury Axle, for Towing, only very few Perentie 110 6X6 on civil hand, the 6X6 cost 3 times more than a UK made 2.5 diesel turbo110 defender 4X4 wagon at time. Today you can see mpic1any Australian SAS (Special Air Serice) at Afghanistan, Iraq and middle east Country. This 1987 JRA 6x6 vehicle imported from Australia to HK at 1999. 2008 we put a new 3.9TD Engine and a new hi speed LT95 gear box ,2 pair rear disc brake for this car, also all new heavy duty half shaft and CV join ( same as Paris to Dakar use ) been fit in all axle.3 unit of ARB air lock and all axle guard, Between middle differentail and rear PTO control switch, we put another switch for control the 3rd axle drive, this make the car can use both 6x4 without middle diff lock and with middle lock for light cross country or 6x6 without middle lock for cross rough country, or even lock all 3 axle for Max off road like a track vehicle. All adjustable shocks been fitted on this car make it go real power to off road. 2009 we will put 3.54:1 gear ratio and 255/85R16 MT tire with heavy duty Military Wolf 16x6.5JJ steel wheel for this car to make the speed up to 120 km/h. For cross country is not a problem, because the LT 95 Heavy duty FC101 type Gearbox with 2 speed transfer case, lo gear ratio is 3.321:1.We may use this vehicle to build a mobile home body to expedition again or use as Rally assistance vehicle at next few year.
JRA 6x6 Land Rover 110 is not same as UK made Defender 6x6, here you can see more about this car. This Perentie 110 is the best Land Rover in the world.
