I would echo Ed's advice as regards batteries. I generally only buy mine from Component Shop and Overlander Batteries.

Two More items for sale

Jump, AliExpress have many suitable Escs as well, I have bought some and and am very happy with them. They do have LiPos but I would get them from a trusted supplier close to home.

ED! Thanks so much! And yes, these are a great starting point!!!
And in the price is on point.
As my lipo experience is supremely limited proper ESC and electronics would be my next step. I have a line on a used boat that is in the Spartan vein (and cheap) that I may have a serious look at to pirate parts for. These links may be of huge assistance.
👍😊

Hey Jump
Take a look at AliExpress, these are 2 possibles

Honestly, I am trying to set aside the funds for a good used Traxxas Spartan so I can yank all the running gear and put it into the Bluebird K-7. The EDF experiment is dying on the vine with that one, but a high speed prop set-up will give me the rooster tail I need to almost reach scale speeds

You got a little excited there Jump!! Don’t blame you, if I had a little extra cash and could swing it, I’d take a little holiday and pick up that Fairmile D. She’s sweet!!

If only Nick!!!! Someday I will crash the party over there! 😉

Jumpugly, live dangerously! Jump on an aeroplane and come on over!

If I could swing I’d be all over that Tamar like a cheap shit, or stink on s&@t, or….
👍😉😂

Paid for Admiralty coaster. I can collect tomorrow...
