Hi,
I'm building the same L-39 from FB. Thank you for the inspiration for attaching the tank :-) I will also rework everything into electricity. Have you flown with the L-39 yet? What is the weight of your L-39? Is the KingTech K-160 sufficient? I am from Europe from the Czech Republic. This is where the Albatros L-39 was born and manufactured :-)
