Losi 8T & SMD Box (OFNA 10244)

On March of last year, Ash from BMM posted a howto on modifying the SMD box to work with the Losi 8IGHT-T

Since then, it’s been countless times that I have had to dig for it to help somebody on the various forums that ask how to do it, so I decided to just post it on my forum, this way I know how to find it in a Hurry .. this is Ash’s (Ashalak ) guide, not mine.

Firstly you need to remove your motors and starting assembly from underneath the starter box, this is easily done by removing the 3 screws as shown:
Once removed you will note that there is actually a second set of three holes on the underside of the starter motor assembly, you need to re-attach the starter motor assembly with the three alternative three mounting holes. This moves the motor assembly more into the centre line of the starter box which helps align the starter wheel much more accurately with the centrally mounted engine in the 8T.
Next we move on to adjusting the guides, first of all the front guide needs to be positioned all the way down toward the edge of the box, and then tighten up the two screws securing the bracket to the lid:
For the rear guide we need to completely remove it in order to remove some material from the underside, this is best achieved with either a very sharp hobby knife or my personal favourite method – The Dremel! The section which we need to remove is the small plastic lug on the underside of the guide, you need to remove this lug entirely ensuring that you make this area entirely flat in relation to the rest of the guide:

Don’t forget to put the nuts in on the underside of the guide for the mounting pegs as you will be required to remove the guide completely again to do so. With the rear guide secured with only one lug slide the guide all the way back and align the whole in the top guide, with the hole in the rear switch mechanism on the starter box. Rather than having an individual screw for securing the lid to the mounting switch, we need to use a slightly longer screw to mount through the rear hole in the guide and into the hole in the switch mechanism:


The final step is simply adjusting the front and rear mounting pegs on the guides in order to secure the chassis. You are also able to move the complete starter motor assembly forward or backwards in relation to the opening in the chassis, this is easily done be loosening off the three screws shown in the first step and positioning the wheel so that it is central with the flywheel opening. Here is what everything should look like when setup correctly:
Hope this helped!

it sure did 🙂
