My headcanon believes that a "Cybertronian helicopter" is nonexistent. If you are of the opinion that Cybertron does not have an atmosphere, then that automatically rules out helicopters as a viable form of transport. If Cybertron does have an atmosphere, while a helicopter would be plausible, it would seem to be an altmode more suited for Earth, where attack copters are the most advanced hover-in-place gunships currently available to human technology, as opposed to a Cybertron, that's been the setting for an eons-long civil war of a highly advanced species; for such an advanced species, the delicate nature of a helicopter's flight controls make it less reliable as a war machine. So, because I wanted to integrate his Targetmaster partners into his altmode, and because he was released in Siege and not Earthrise, I modded Spinister to be a Cybertronian gunship. Apologies ahead of time if I mess up pic posting; this would be my first post trying to do this. Mr. Spinister: --Removed his rotors. Filled the holes in his tail from removing the tail rotor. His tail popped off easily, but the main was a little more difficult. After cutting away some of the rotor mount, I managed to grind down the pin's head to slide the rotors off (in case i ever want to repurpose them later), then had to cut the entire mount off the main body. --Plugged the 5mm ports in his legs (normally they don't bother me but due to the nature of his transformation I didn't like that it was only on one side in alt mode. --Removed the landing gear. Maybe I will add a gun instead if I can find something that will mount there easily. --Added a T-connector and a pair of guns from shapeways under his tail (the T-connector is glued on). --Cut down the plastic reinforcement between his gatlings. Cut down some brads of similar diameter to his gatling barrels and glued them on the underside to fill out the hollowness. --Filled in the underside of his other stock gun barrels with putty to fill it out. --And of course, additional paint details. . His buddies Singe and Hairsplitter: --Some additional silver and black detailing to Singe. Also a little bit of red for the (negative space) detailing surrounding the "coils" under his pecs. Added a leftover titan master decepticon logo reprolabel. --Didn't think I could palette-match Hairsplitter's purple when adding paint detailing so I just repainted his purple in its entirety. Also some silver, black, and white detailing. Painted his eye-visor red. Will add another titan master decepticon logo if I can find another one in my pile. Together: Gunship: --Bought two other big rifles from shapeways, and sawed off the stocks so they looked less rifle-y, and made use of the pair of 5mm ports that were unusable due to his main rotor. This is really my first legit mod and I kinda dig it. Thanks for looking!
