I am building one, modified heavily.
You will find it is a straghtforward standard build. You have the advantages of a high quality kit. The best,most accurate Akula kit out there. It helps to have that edge!
A standard 3.5 or even a 3 inch WTC will work.
Just get on the bench and be fearless!
Dont worry about mistakes too much. Anything can be fixed. You will find you try not to make mistakes so it goes faster, that's all.
My build thread is actually on the build thread. (see 4th gen akula). I will be posting my latest efforts hopefully in about a week.
Feel free to email me with any questions.
