The Difference between versions


Hi all

I really want to try and build one of the openrov’s

i just really wanna know the Difference between the 2.6 2.7 and 2.8
because for me the frame looks pretty simular? or is it just the board ?


Welcome to the forum and the community. If you want to build one I would definitely recommend going with the latest model (v2.8 right now) as we make significant changes to the design with every model.

If you want to build a 2.8 we sell all of the ROV components on our store.

Here are the release notes for the 2.7 and 2.8 which will tell you what the major changes were.
Version 2.7 Release Notes.

Version 2.8 Release Notes.

Short Summary 2.6 to 2.7

  • New motors and props that are more efficient and provide more thrust.
  • ESCs hard mounted and programmed on controller board rather than having to solder them and program them.
  • DB-25 pre-wired and color coded.
  • Light board added.

Short Summary 2.7 to 2.8

  • New battery tube endcaps that are twistlock to make changing batteries a breeze.
  • DB-25 built into endcap to make electronics installation easier.
  • Pre-wired more external wires for expansion.
  • Much faster build time.


Mikkel, Having completed a 2.6 build, modified it to a 2.7, and then subsequently completed a 2.8, I just want to underscore the wisdom of Brian’s recommendation. If at all possible, go with the latest version available (2.8). It will save you many hours and lots of angst!


thanks for your response, I have just brought the 2.8, from the webshop :wink:


@mikkelsg26c I hope you enjoy the build!
