would this be a good conversion for a direct drive?

Wow, disc brakes on each wheel!

The gas version looks slow. I would consider a Neu 2215/2.5Y powered by a PowerJazz on 14S lipo.

The guy said the car weights 20 lbs... so when you take out that heavy engine, and all components not needed, your weight goes down significantly. WHen all said and done, the total weight could quite possibly be less than the gas version, RTR.

I've read it somewhere that 700 watts of electric power equals 1 horsepower? Is this correct?

If so, the HXT 80-100-A 180Kv Brushless Outrunner is a 10 horse motor!

I just bought a HXT 80-100-A 180Kv Brushless Outrunner. It is HUGE. I'm thinking about doing an Electric Bicycle with it. Running the ESC that you have pictured and power it with 36 volt Dewalt packs.

You'll never get the diffs to hold up to that motor. Which btw, before you decide on a vehicle to do a Direct Drive to Diff conversion on, take a close look at the diffs and the gear ratios of those diffs. What's the diff ratio on this car? Are they upgradeable or tough already?

The dual outrunner thing might be pretty interesting, but the rear diff ALWAYS see the majority of the load. The rear is where you would see the most amp draw and is where the most useable power would find it way to the ground.

I think it would add another element of uncontrollability. The front being powered the same as the rear but not connected to each other, would make the front wheels spin their ass off, while the rear was getting under the load and doing the work.

The front tries to lift when you accelerate hard. This reduces traction there alot by itself. With actual tire speed not being equal, It would get out of hand pretty quick.

That's a cool looking car though.

Hey sike, I threw up a thread of my newest proposed project. If the dual out runners were connected by a center driveshaft, would that work better? I am sure that they would have to be timed together, and maybe that would not work either, or have a clutch to connect them at a certain speed.

If they were connected and each had their own ESC, they wouldn't have to be timed any particuliar way. Each having their own ESC, each motor would have it's own EMF feedback to their respective ESC. Being independantly controlled like this, it would work without timing to each other.

It's when you try to control two motors with one ESC that timing is critical, and even then I hear of issues.

I think having them connected would probably work better. All theory at this point though.

Well, looks like I need to sell a few veehicles and buy up what I need. This may have to wait until I get my pair of LSP conversions done. One will have an 8xl on 5s thru a monster 125b. The other will have a kb45 9l on 5s thru and airmaster 125. With mech brakes and a solid center drive. The 1st will be an off road racer and the 2nd will be an on road drag truggy. Should be able to start them this weekend.
