Future Project: 1/8 Buggy *CAD Renderings* -
03-26-2007, 05:31 PM
Hello,
Last night I decided after seeing a few converted buggies I would give it a try. So first thing I did was look into electronics for it. Lipoly's: (2) TrueRC's 4000mAh 11.1V 3S1P packs Motor: Neu 1512/2D Brushless Motor. Controller: Undecided. My starting base vehicle is an Ofna 9.5. ALOT of these stock parts will be replace with others from other buggies or custom machined. I have already replaced the stock a-arms with those off of the Ofna CR. I have decided that I will CAD the whole vehicle to a very detailed point(that is why I have only gotten this much done in the rendering so far). I hope to get everything to their exact measurements so I know where exactly everything will work, and if needed where I can move around stuff to get it to work. My plans for the buggy is first for run time, and second for speed. I would still like to have a even amount of both. Is 65mph aiming too high? I put some numbers into the speed calculator here on the site and I was around 85MPH with all the gearing correct and everything. I just dont think when it comes down to it I will be near that. Still have alot of Rendering to do still. *Note* Resizing them took away a little detail in the renderings    My Favorite picture so far:

Thanks Guys, I hope by the time that I get this thing into the final proto phase, the new Kyosho Big Bores will be available for it. Tonight I hope to get some "pins" put onto the tires to give it a more detailed look.

Motorxer4life, please stop posting useless posts.
I was just looking around threw some scrap metal, and I realized that I have a large enough sheet of .100" thick titanium that will work for this design, so I am going to see if anyone around here can "Tiodize" the titanium chassis black.

looks like a good design, is the motor gonig to be dead centered like that?? if so sounds like that should be a good way to place it Losi 8ight with v-spec

I know someone who used the 1512 motor, and a 5s lipo setup. VERY fast. But not 65mph, and 85mph would require more. I'd imagine that 55mph is well within the reach.
First, those big wheels that buggies use they aren't aerodynamic at all. The exposed suspension arms, etc... Also, the AWD system with its 3 diffs creates parasitic loss. If top speed is your goal go for removing the front diff, and creating it as a RWD platform. A 2spd transmission from an OFNA Ultra GTP would go quite a ways towards your 65mph goal. Buggies are better off than truggies or monster trucks when it comes to drag, but that big wing to keep them stable causes lots of drag. Its possible to eek another 5mph or so out of a buggy by removing the wing as long as its drag limited and not gearing limited. My Jammin buggy clocked 53mph on a Sheriff's Stalker radar gun with a OS 30vg using 30% nitro and a 15t CB. This was in a small parking lot with about 150ft of running room. Not very much. Using a GPS we clocked my 528xr powered LSP at 39.6mph using a 15t clutchbell. However, the engine was only temping 170* and I broke a hub (stupid freakin hubs) before I could tune it leaner.

Yes, it is in the center of the chassis widthwise, but it is not lengthwise. I did this because mainly I want an even balance upon each side, and also to give more traction to the rear.
Speed isant my only goal, I was just crunching in the numbers that I am using for this project into the speed calculator, and these were the speeds coming out of it. I mainly am a basher so a little speed is always fun while bashing.
