Hi, having not found a feedback thread for MP-04 I thought I'd start one. First a bit of background on me as I'm new here; I’m an original G1 fan, there at the beginning, my first transformers were G1 Optimus Prime and Jetfire followed swiftly by Starscream and many many more. I didn't watch the cartoon much, although I had a couple of episodes on VHS. My main Transformers influence was the UK comic. My last Transformer before I moved on was Snaptrap from the Seacons. Until about three months ago, I didn't own a single transformer, and then I discovered Binaltechs! And then Masterpiece! I now have 4 Binaltechs, MP-03 Starscream, A Yamoto VF-1S with Stealth Super/Strike Packs acting as my Masterpiece Jetfire, and a Yamoto Koenig Monster. And Now MP-04! On to the Review. My first impressions were good, the box is large and in the same style as MP-03 and the previous MP series I understand, I only own MP-03. Opening the Box reveals two more plain boxes, containing the robot and the trailer respectively. The plain the boxes contain a cardboard inset which holds the plastic "tray" to which the Robot is very well secured, with very many twist-ties. The Trailer is held by two plastic "end" pieces. Overall very well packed, the twist-ties are perhaps a bit excessive, but I'd rather have that than a broken toy. Optimus Prime: I won't go into too much detail as he is apparently nigh on identical to MP-01. Good god he's heavy! I can understand why people who had MP-01 were disappointed with MP-03; however I can say that MP-04 has not dulled my enthusiasm for Screamer in any way. He is packed in robot mode, which unfortunately means that you don't get the slow reveal of the Robot from alt mode that I enjoyed so much with my other TFs. Pros Dicast, it just gives a toy weight and a quality feel, which you can't seem to get from plastic. Looks, He's Optimus Prime, he just is! Accessories, The Megatron Gun is just the coolest thing ever and despite being a bit big looks great in Screamers hands. The Energon axe is cool too. Details, all the hydraulic pistons on his arms and legs, the vents that open on his legs and the communicator flaps on his arms with Megs and Grimlock on them. Cons Dicast, I have a couple of paint chips on the chest window frames. Looks, My god his head is big, is it me or is his head really big? Plus his alt mode is quite poor compared to Binaltechs and MP-03. Hands, a little weak on mine his rifle flops about a bit when held. Weight, he's very heavy and that can make him a bit difficult to pose, plus if he fell off the shelf I think he might go through the floorboards! Overall Very impressed the Minor problems are more than made up for by the Pros. Trailer: The trailer is a good replica of the cartoon version, all the expected external details are there. It is lighter than the rig section, and there is no dicast that I have found. The Trailer has a fold down stand at the front that allows the trailer to stay level when not attached to the Rig section. A fun feature of this (at least on mine) is if you reverse the Rig section up to the trailer it will fold the stand away and actually attach itself to the rig. I don’t know if this was a designed feature or a happy coincidence, but it’s cool none the less. A bit further down the trailer are the fold out stabilisers that are similar to the original trailer, these version fold out 90deg and then have a section that slides down to make contact with the ground. At the back are the suspended double axles, with four rubber tyres. Unlike the Original trailer the rear doors fold out like a real box trailer, however they only open 90deg, well about 89 actually. This reveals the ramp inside that folds down to allow access to the inside of the trailer for your Binaltechs to hide in. Opening the trailer to reveal the inside, you find the robot repair/gun platform thingy (I don’t know what to call it) but no Roller which is a bit of a shame. The Repair robot articulates in all the same ways as the original, plus the “packs” on the side that contain the lasers and hold the two manipulators also rotate 360deg. This allows the robot arm to be a bit more flexible than I remember the original. Unlike some of the promotional photos the lasers and the canopy of the repair robot are translucent red, not solid. The inside of the trailer is quite plain in colour it’s all silver, unlike the original that had stickers depicting various screens and controls. It does have a lot of moulded in detail however that could be painted to bring a bit of life to the interior. It also has places to store all three accessories which is useful. Pros: It exists, let’s face it any G1 Prime needs a Trailer and this is it! Auto Hitch, if it’s a coincidence I don’t care it’s cool. Binaltechs/Alternators fit inside. Cons: Plastic, it’s a bit light compared to the rig, and the plastic used on the shell seems a bit flimsy and cheap. No Roller. Lack of colour detail on the inside makes it look a bit cheap. It’s Huge; I have nowhere to put this! I am now skint! Overall: A very good addition to an already excellent toy, not quite up to the standards set by the Rig section but very good none the less. I am very pleased with this toy, I had to really search for any cons at all. I highly recommend it to anyone who does not have MP-01. If you do have MP-01 then your choice is a bit more complex, I’m not sure I would pay £110 if I just wanted the trailer. I hope that’s been useful Simon.
