Tamiya Nissan Sumo Power GT-R - bugman72 - 01-15-2014

After seeing lexury's take on this body and just buying a Sakura D3 chassis, I felt compelled to honor lexury's amazing work and make one of my own. Warning...this is going to be a long post. I'm excited to finally show this body off and I want to describe all of what I have done. If you get bored, you can just skip to the pics. Smile

The body is a Tamiya Sumo Power Nissan GT-R (lightweight) and has had quite a bit of work done to it. All of the vents and ducts have been opened and filled with screen mesh, where needed. I used the decal sheet that came with the body, placed some of them onto .030" lexan and then cut them out to give them some detail. The Nissan emblem on the rear decklid is actually two levels high. The Nissan script is on a separate piece that was glued onto the circular part of the emblem.

I created tow pulls using 12GA electrical ring terminals painted yellow. Rear exhaust tips were created from aluminum tubing. I used a detail set from R2Hobbies for the windshield wiper, intercooler and disc brake rotors. The rotors' vent holes were drilled out by hand with a 0.6mm drill bit (64 holes for each rotor) and then painted. The body was first painted with silver on the inside, then flat black on the outside. I can't find a supplier for Tamiya's PS55, so I had to go with standard flat black enamel. I use this same technique on my rock crawlers, so I know that the finish is actually pretty durable. I used straight pin heads for the rivets on the front end.

Lights...went a little bit overboard here. There are 21 LEDs in total on the body. There are 4 channels dedicated to the lighting on my modified Flysky GT-3B, one of which is for functional brake lights. Brake lights consist of 12 pieces of fiber optic cable for each tail light that collects at a pair of 5mm red LEDs. I have also added a central warning light in the center of the rear bumper. This circuit is mixed with the throttle channel and will come on as soon as you let off of the throttle or apply brakes. In addition, there are 4 LEDs for the taillights, two 1206 SMDs in each side marker light and a pair of amber parking lights in the headlight housing. These are on their own channel and can be turned on and off independently from any other channel. I then have two channels dedicated to the headlights. The low beam and high beam lights can be turned on independently from each other. One thing to note...I do intend on going back and changing the resistor values of the headlights. I think the value is too high and as a result, the lights aren't as bright as I would wish them to be.

Now, with having 21 LEDs over 4 channels, my concern was directed towards how to connect them to the receiver on the chassis and still be able to easily remove the body. I think that what I came up with works perfect and now I don't have to worry about wires getting into the belt system. I used a section of CAT5 ethernet cable on the body as well as part of an ethernet coupler on the chassis. Since there are four channels, I needed 8 wires (4 pair), which was perfect for an ethernet cable. I then used a hollowed out servo case to store the four sub-micro servo boards, which I use as light controllers, and then wired them up the the corresponding wires on the ethernet coupler. Now, taking the body off is as simple as four body clips and disconnecting the ethernet cable. Simple and elegant. Smile

So, enough with the chatter. Here are the pics. I wish I could have had some more professional shots taken, but I haven't had the chance to yet. You may also see a random Siberian Husky hair here and there. I tried to remove as much as possible, but that stuff seems to be attracted to the body.

Here's a link to the entire album, where you can see some in-progress shots as well.

RE: Tamiya Nissan Sumo Power GT-R - lougc8 - 01-15-2014

wow that wiring and led lights setup is amazing.

RE: Tamiya Nissan Sumo Power GT-R - bugman72 - 01-16-2014

Thanks everyone! Very happy with how it turned out. Can't wait to get some drift time with it.

Always appreciate a job well done. and you sir have done a darn good job!

RE: Tamiya Nissan Sumo Power GT-R - lexury - 01-16-2014

wow man flattered with what you did there, clean cuts and fine take on the sumo. may i suggest that you paint the wing flat aswell so it will match up with the whole theme, Pickled got his gtr-35 now and i believe his using it already. again man, well deserved applaud from all of us here at LH Ave Garage.

I've been debating whether to do something different with the wing. I've contemplated going flat black, but I've also thought about carbon fiber, which may end up being too "flashy" for the body. And thank you for the compliments. It was the body that you did for pickled that made me decide to get it. I had been tossing around the idea of a couple different bodies (Lexus LFA, Skyline R33). May still get the LFA, but have concerns of whether it will fit properly with the front-motor chassis.
