Hey arracheur de patate that's pretty impressive

A very nice project, and for once someting different from those endless boring "me too"'s A-4's and F-16's

Where'r you'r going to put your batts? I guess you have plenty of space around the duct?

A bientot, hwh

Sorry for you Dog, we also missed our 16 1/2 Golden "Brie" But 18 this is a very good life !!
Not much room for the cells , I have choice around duct or the long chin behind cockpit . I will glass the hole fuselage with the wing and I will cut the hatches: Cells, fan, retract. The front wheel is the headache. Not much clearance there for the wheel.
Anyway... back to the basement

Since last post I struggle to build the !!!@#@@! rudder I was not happy with the result , finally I cut the hole thing and I cut a foam core Next will be the vacuum bag proceed with "gorilla" glue and 1/16 balsa. Foam is definitively easy to work with.
I "pained "the fuselage with dry wall filler. Next will be a messy and long sanding job.
A+

After struggling with other project I spent some time with the Mig today.
I finish the vertical stab ,cut foam and vacu-form balsa with gorilla glue . I carve some balsa for the top....
I add the exhaust cone in foam.…
AND started the stab , very light balsa build . Each stab will be control by a Hitec digital wing servo. Not much room for that but will be a solid and direct control on elevator . Unfortunately will be not scale all moving tail but " c'est la vie"

The wings are done , now I have to install ailerons , rudder and 2 servos for elevator.
Next is glassing the wing and fuse together, glue rudder in place and stab.
Sorry I don't go deeper in the building maybe later when I need more advice

I love it JC ... keep posting.

How do you make sure the wings will stay on ... I can't see what they had in mind.

I have seen the plan on ebay, maybe I'll get it too if I can see how yours progresses

Great work J-C,

The Mig is a challenging build because of the intake for a scratch. I watched my brother Greg really engineer some great ideas in his but the intake got him. I think you’re right on with your build. I meet you at E-jets banquet and enjoyed the good round table talks and discussing Greg’s intake dilemma. Here is the link to his build.
