Build-blog:

Since i had several sheets of 6mm depron sitting in my basement, I decided to try to make a foam plane. I spent some time in the Scratchbuilt section of RCGroups (http://www.rcgroups.com/foamies-scratchbuilt-428/) and decided to try to build the Prime8.

I would like it to turn out something like this:

- Glued the spars

Decided to use 4mm flat CF, and slot the wing fully through. Used foam safe CA, not sure how clever that is.
In hindsight, I made the slots too "wide", the glue does not expand, and does not form a full seal on both sides of the CF everywhere.
For next attempt I should try a CF tube or rod, and "router" a slot for it using a Dremel

- Cut out some more parts

28.10.2011:

- Did a little more cutting and fitting

30.10.2011:

- Glued main fuselage sides and vertical stabilizers. The angled vert-stabs, make it so that Aileron full travel is not possible, need to modify ailerons.

15.11.2011:

Motor, ESC, Battery and Rx arrived today!
Fitted the motor, ESC and Rx. Need to buy JST connectors for the ESC

16.11.2011:

Added JST connector and fitted battery. Needed some trick to keep servo's in place, so "extended" the servo pods to hold them.

Ready for maiden!!
