Here it is! 1/8 Electric Taken to the Next Level!
#16
We need more purpose built, ground up 1/8 Electrics. Sooner the better.
I was told by many people in the RC racing industry that 1/8 scale is the most popular class of all RCs combined. Even if that was for the nitro class of RC's, Electric 1/8 scales popularity has exploded over the past two years, and the 1/8th scale Electric buggies popularity continues to grow exponentially from month to month. I think every major RC manufacturer is working on a ground up Electric 1/8 scale buggy. Or they should be working on a ground up Electric. I know I'm very happy with my Hyper 9e, and it's the furthest from a nitro conversion Buggy I've seen. And I'm most satisfied with the center diff having been moved to the rear of the buggy, just in front of the rear diff. It's a low maintnance easy to work on layout. Though it would be nice to see many more purpose built electric 1/8 scales available. It seems it's only a matter of time. I'm just glad I don't have to wait anymore. I'm very happy with the Hyper 9e.
That's a nice looking chassis conversion. 6.6lbs. sounds almost impossible, what's still missing? I don't think it's revolutionary though. Keep in mind that the reason you haven't seen a ground-up electric 1/8th car is because 1/8th electric is still too small to constitute a business for a major manufatcurer. Remember what truggies looked like in the beginning (longer chassis plates and axle extenders)? Just because they aren't doing something doesn't mean they can't.

It may be the most popular form of racing but if you look at how frequently RC tracks come and go it puts things in perspective. Racing is a very small part of R/C cars as a business and electric is still a small fraction of 1/8th scale. It has a long way to go before it becomes popular enough for a company to bet on a ground up, dedicated electric 1/8th platform. The opportunity right now is for guys like the OP who can do better conversions than the big companies are willing to do right now.

You definitely need a rear chassis brace on that car. And velcro on the batts, I don't think that would hold very well. We all take some tumbles during a heat/race and I think those would come loose. They still need to be in a tray with straps.
Cool idea though, it does look pretty good!

Very impressive work on the chassis and so much effort put into it. I agree with the chassis brace or an upper deck.

Na, they really haven't become that popular with E-1/8ths. The small advantage of brake bias just doesn't seem to outweigh the disadvantages of more moving parts, brake fade and the weight that comes with them.
I like the chassis design! I was thinking of something similar myself until I ran into the rear gearbox problem (the offset input shaft). This car can be very skinny if you use the dirt guards from a Tekno car and find someone to make a nice body for it. You could take it a step farther and do the bottom loading batteries with quick releases. That would be a good project for an engineering student.
Great job so far, keep at it.

What type of CAD software did you use to create the parts? I am a ME student as well, I just finished up taking finite element analysis. we used solidworks for the metal and catia for the composites. Did you get a chance to run any kind of stress simulations on the chassis? I had a lot of fun trying to get things to fail after building them. What school do you go to? I am at Temple University in Philly. Looks like you might have you senior project already finished.

The Caster Fusion is close, front motor, 2 battery trays down the center, drive shafts are straight..the center diff is not as close as what yours is to the front diff, but the way Caster did theirs it puts the motor across from the servo..I guess you didn't look hard enough..your is still good but I think it might need some form of bracing to keep the drive shafts and gears safe from the "not so gentle drivers..but nice job..oh and Caster has had the Fusion out for 3 years..so the "ideas" have been out there..the big boys just believe that theirs not enough money in electric to warent a whole new design when the conversions are not really much slower..their opinion not mine..

Well, I will just write here instead of PMing you. I suggest you take a closer look at the Caster Racing Fusion. Everything we did is for a reason. I will say that you get an A for effort and I personally think it is great doing what you did, but in reality, all you did was turn a Losi into a Caster that has the motor flipped the other way with the diff placed up front which will create issues that I think you will notice after getting some run time at several different tracks.

What does that mean? In the middle of my comment I gave him an A for effort and applauded his effort. What more should I do?
I personally think there will be issues with that design, I am keeping my comments to myself, and life goes on.
