ive seen a ofna 9.5 that some guy converted to run on bateries. he just used the same system that the emaxx uses and made some custom mounts. there was a video and it was pretty damn quick.

yea i saw it in rc driver. it was pretty cool. it had the e-maxx dual motor setup with the titan motors. but still its electric and doesnt make a loud noise so its worthless

Right now I'm all in the nitro thing because i love to race and the electric class(es) I used to race have died off. That and I'm having a hoot racing MT. But when it happens you can say you saw it here first. What i'm refering to is when MT and 8th buggy come to be dominated by electric. The motor technology already exists to build electric cars that are both quicker off the turns and faster on the top and it's just a matter of time before energy storage, (that would be batteries) reaches a point where big electrics can go 45 minutes to an hour. It's gonna be a sad day for nitro when that time comes. Of course when it does, the nitro diehards will demand a seperate class so they can keep on struggling with their stinky, messy race cars while the simple, clean, and noiseless electrics put down the best lap times.
I'm not a nitro hater by any means folks, I'm just telling you what's coming.

I agree with you a bit on the impending dominance of electric RCs.
I've been a avid r/c heli enthusiast for some time now and around 4 years ago, the idea of an electric heli outperforming a nitro one was a pipe dream. Now, we have e-helis that can do everything (and them some) nitro helis can do. They all have amazing performance. All that's limiting them is the high price of batteries (try 32 cells) as well as brushless motor setups.
But I'm sure economics will bring the price down when the market accepts it.
By then we'll probably have "simulated" nitro engine noise for those who can't run RC without the roar of IC engines.

I have not decided on what motor I will use yet. But I will be using an MTroniks ESC -
I am converting my Hyper 7 to be an all electric brushless setup. This month I start a machining class and should also be starting a CAD class as well for the winter semester at Harrogate College. My class project will be converting my Hyper 7 to be all electric. If my 9.5 does not sell, I will convert it as well.
A lot of the work and figuring out, you are on your own. But here is a video of an all electric 1/8 converted buggy. I will only leave it up for a week or two and then take it off line because it takes up to much room on my server. So download it soon - I might not post it up again later. When ever this kind of stuff is on my site, it uses all my monthly bandwidth people downloading them over and over again.

The cheap basic series lehner motors have loads of torque and can be used in 1/8 scale application with no worries. A lot of people on RCU will tell you that they will not hold up. The video here is this link is using a basic series Lehner motor

Remember this was not my buggy. Nor was I there. I got it from a friend who has done many of these conversions himself. I decided I will convert mine to electric and race it in the 1/8 scale nitro class. [X(][>:]
Gotta love it.
The cool part is it rains here all the time. I have an MTroniks ESC which they will be making them water proof soon. Well I also have an MTroniks water proof receiver. So once I get my water proof version of the ESC. I can play ALL DAY LONG in the rain or sun. Winter time it rains here constantly.
You can do the same setup with brushed motors. I just choose to never go back to brushed motors. They are to much work.
Hope that was helpful.

holy crap i want to convert my hyper to brushless now![:@]
what would that setup cost that was used in the brushless 7.5 vid? what about expected runtime? if i could afford enough batteries/have them last long enough to get a total 30min of runtime i think i'd be happy.

Depends on setup and gearing. Like any electric. The taller the gearing, the shorter the run time. I am thinking of using a 15t pinion.
See I have an advantage. I already have the brushless motors and ESC's and batteries. All I need are the correct pinions and make a motor mount on my CNC Mill. I will most likely make my own chassis. I do now want all the extra holes left over from the nitro chassis and want to save the original chassis incase later I want to go back to nitro.
On average expect anywhere from 10 - 20 minute run times. Even though they are very dangerous because cars draw more amps from batteries than planes. LiPos will give you longer run times.

For the ESC - you want an ESC that can handle minimum of 90 - 100 amps. The size and amount of amps it takes to make a buggy move like that is insane.

where can i buy this stuff though? if i could get going for under $600 or 700 i think it would be doable by next summer. i'd actually prefer lower gearing because its the low end torque that makes me grin ear to ear

yea right now nitro racing is almost cheaper then racing mod electric, but eventually electric will just be the norm with all the motor and battery research going on its only a matter of time.

It is all about preference though. If you want all the nitro and the work and so forth. Then stick with it. It is not for everyone.
