    Thumbs up Sidewinder SCT connected to stock 380 VXL

    So, I have the stock 380 connected to my SCT and it's great. The SCT barely gets warm and the motor is pretty warm (so need a fan). Anyway, for those of you interested you do the following:

    1. Start with stock motor
    2. Press new Castle bullets onto the end (so the stock male connector goes into the back of the Castle connector where the wires usually go).
    3. Solder the pins together
    4. Cover with shrink wrap

    And your done. This was incredibly easy and didn't require cutting off the old connectors. I don't intend to go back to a stock ESC so the connectors are on there for good.

    One issue I found is that the connectors are extremely tight fitting together. The connectors on the SCT are 4mm and that's what I got, but they were so tight putting them together that I don't know if I'll be able to pull them apart without pliers. Is this pretty common for brand new Castle bullets? I did check and there was no solder in between the cuts on the male end (I've been soldering for years).

    Am I understanding this right, you soldered the 4mm connector onto the stock 3.5mm connector? I think it would be better to remove the 3.5mm connector and solder the wire directly into the new 4mm connector.

    @dadx2mj - I was being lazy and the stock 3.5mm connectors fit perfect in the back of the Castle 4mm connectors. It's like they were made for that. I know the correct way to do it is to cut the other connectors off and put the new ones on but that was fast and easy.

    @double G - if it quits then I'll get a new Castle or have it fixed

    Anyway, are the new Castle 4mm supposed to be super tight when sliding together though?

    mine on a new sv2 5600kv combo are extremely tight. Am going to replace them with some other 4mm connectors that work more like the traxxas ones.

    This is just like using an adapter, it might appear to work just fine but it is adding resistance to the system and not the best idea for performance.

    Congrats, you're lazy! =P
    And I used a pair of pliers to pinch the "male" end of my 4mm bullets to fit a little better. Don't pinch them too much though or you'll have yourself the classic hotdog/hallway situation.

    Thanks for the notes guys. The MERV runs with the ESC set to deliver only 50% max power (so like training mode) total and it's geared with a 55t spur and 19t or 16t pinion (can't remember which one I put in there) so I don't think there's any maxing out of the system (it's for my 3 year old so he doesn't need it to go full speed).
