My Original Review of the JRX Giftset reads: "Despite 33 quid in customs charges I'm rather pleased with the new kit I got today...
Starscream and BB is a rather nice recolour of the existing G2 ATB which I suspect most of you have - nice toy, the yellow live edge works well....
JRX giftset: Surprisingly these don't come packaged in robot or train mode, but in the configurations to build JRX. Robot was a little unstable at first but some fiddling helped. He's got the benefit of the wheels for the leg robot (which is which ?) as a balance. All the individual trains are nice and the robots are rather good with my only complaint being that the legs are slightly too long for all 3 robots. Nice heads - one of which looks like JRX's and one that resembles Airazor. "
If I recall correctly JRX stands for Japanese Robot eXpress.
In theory JRX has a vehicle mode as all three trains can be jointed to each other end to front by the peg and hole system they use.
Assuming you don't own the giftset and just plug em together out the box here's how to TF the trains into combined robot mode.
J-5: Open the front of the train out, raise up JRX's head and close the front of the train. Remove the rear hook, gun barrel and stock/battery box. Pull back on the train extending the individual robot legs. Split the legs and waist in half and fold to the sides so they're flat along the side of the train. Fold the outer part of train side back on the last hinge before the shoulder rotating joint for the combined robot.. Fold forward the panels either side of where the legs are bent out. Flip the robot feet up. Pull the combined robot hands out of the bottom of the individual robot legs - now obviously JRX's arms. Fold the thumbs up. Swing the arms down at the shoulders so they hang down beside where's the robot's body would be.
J-7: Fold the nose down from behind the two small blue windows but in front of the large one. Turn the rest of the nose round and pull down on it relative to the train's body. Remove the back panel and connecting hook. Extend the legs and fold to the sides. Fold out the back wheels and extend the feet. Fold the back wheels back in, and fold the feet out. Fold out the arm panels and fold down. Fold the waist into the gap. Straighten the arms and fold so they point up behind the back of the legs. Fold the legs down as a thruster pack.
Lock J-5 onto the top of J-7 - the groove under the back of J-5 slides over the black bar on the top of J-7 and the clips lock together.
J-4: Remove the loading hook and the connected tube from the back of the train. Flip up the panels on the top of the train and remove the missile launcher from under the back panel. Rotate the entirety of the front and the back relative to the middle of the train so that all of it but especially the grey bits connecting them to the middle are the other way up. Fold the front & back of the train down under the middle to form the legs. Turn the train's nose round so it faces out of the blue side of the leg. Pull the nose out then fold it upwards to form a foot, then fold the wheels back to form a heel spur. Fold the wheels up on the other leg and pull down on them to extend the back of the train. Turn so the wheels are at the back. Fold the back of the train out to form the other foot.
Clip J-7 into the top of J-4 and push the peg on the inside of J-7's nose into J-4's bottom.
Take the light up cannon J-5 uses, bend the stock/battery box up and have the hook hanging down underneath. Fold the peg out of the back of J-4's missile launcher and place into the barrel of J-5's weapon with the LED nestling in the slot in the back of J-4's weapon. Fold the hook on J-5's weapon down. Lock the gun barrel of J-4's weapon into place and fold the hook on it down so it locks with the hook on J-5's weapon. Place in JRX's hand and lock round the weapon. Insert the missile into the shield on J-7's weapon and hold in the other hand
The combined robot form works due to the similarity in colours and style between J-4 & J-5. J-7 is pretty anonymous from the front just being a small amount of lower body space, but providing the thruster pack at the rear. He feels more useful than the poor robots that end up on the bottom of the Micromaster Six combiners but not much ! The thruster "legs" can also be swung up over his shoulders and used as cannons or rotated the other way up as wings so there are some options there for you. The impression J-7 is a bit of a spare part remains though.
He's got all of J-4's leg articulation: he bends & turns at the knees and his hips move forward & back and to the sides. The head is mounted on a ball joint which is in turn mounted on an arm that bends. The shoulder pads move forward & back at the shoulders. There's a ball joint mounted on the shoulder pads that connects to the alarm that allows the arms to swing up. The arms bend at the elbow in the correct manner, fold to the side just bellow it and have a rotating joint just bellow that. The thumb can either be raised or opposed to the other fingers and the fingers can be partially open or bent in to complete a fist.
I mentioned in J-7's review that I'd popped all four heads off while reviewing these toys. JRX was by far the worst to fix as I just couldn't push the ball joint back into the socket ok. I ended up having to dismantle JRX's head to complete the repair.
Overall: Solid combiner with decent articulation. However one part is essentially reduced to backpack kibble in combined mode which makes you think that the finished result could have been achieved with one less Transformer and a more streamlined combined robot.
I intimated earlier that at £15 each the Bullet Team don't provide that good value for money. Well Rail Racer isn't £45 of robot. Perhaps an alternative giftset solution may have been more appropriate for these toys ?
