    I don't think that's a good idea because the Optima buggy wasn't designed with that in mind. Moderate brushless and lipo power is okay, but more than that you'll probably grenade the transmission. Especially trying to get Revo power. You would have better luck getting the rerelease which is more durable and can handle more power.

    I agree with Antho. Just restored my own orginal 1988 Turbo Optima to running condition, using some modern electronics. I like the idea that it still does what it was made to do, but i have no intention to compete with modern buggies, even though the re-release should make it easier to get spare parts.
    Considering what else you need to get everything going, I wonder if hopping up an old Optima would really be that much cheaper than a modern RTR buggy. I don't know enough about modern buggies to make any recommedations, but I'm sure you're in good company here to find some good ideas.

    I think you should start with a 2s lipo. I'm not sure what brushless combo would be good for the optima, I'm guessing something similar to what people are putting in the rerelease.

    If the motor is 540 sized then that combo should be good. I would use a 2s lipo.

    Just as a warning I grenaded a high performance ball bearing diff on a Tamiya buggy by going 2S lipo and a 3300kv motor. Just so you know, the torque is higher than brushed and you don't know what won't accept the power you're about to put through it.

    But you won't know till you try :D

    I upgraded my gold pan RC10 that I built when i was 14 to brushless and lipo. I have a Castle 3300kv running on 2s. It's no revo, but its fun. I can still pull wheelies for about 50' on the right surface. (I also have a brushless revo I run on 4s.. That one will pull wheelies all the way down the street, I've even flipped it a couple times despite having wheelie bars) But honestly, I'm glad I didnt go bonkers with power in it.

    Some tips to keep in mind:
    be sure to upgrade from bushings to bearings.
    Raid the parts bin for newer models of your buggy. I have control arms and driveshafts from a B4 on my first gen, as well as 2.2 wheels. I also swapped from the stupid E-clips to the traxxas style screws.
    I still have a TON of slop in my steering, makes handling at speed difficult. I still have no idea how to correct that, but redistributing weight helped out some.
