RSVP MX Tutorial
For the insert: Z-Circuit: http://modhouz.blogspot.sg/2012/03/fi...
Take note the dimensions are 8.6cm x 3.3cm (it should actually be 8.8cm x 3.3cm)
The HGG grip is not very easy to take out. You might want to buy a HGG tip and grip set from Penwish.
Otherwise, this tutorial should be quite OK if you have patience in making the RSVP MX. 😀
