Welcome to the final episode in our foam kit bashing series! It was quite the journey getting here and I actually didn’t intend on it taking as long as it has to document the whole series, but life has been crazy with no signs of slowing down it seems (plus, I just started a new position at work!). If you’ve just found this series, we have gone through and completely transformed a Freewing Mirage 2000 into an Isreali Kfir. As a part of that, we covered the transformation process talking through the building methods in converting the airplane using balsa wood and foam, we’ve talked about painting and finishing and we’ve also covered how to make panel lines and add realistic weathering. I hope that you guys have enjoyed the series and are geared up with some new techniques to try on your models! To finish this series up, I thought it would be best done providing a little discussion on how the airplane flies in it’s new form as well as some of the things that were done in wrapping the airplane up and getting it tuned in the air. Also, I had a little incident with the airplane at the Warbirds & Classics event which tore out the right main landing gear mount. So, I thought it would be a good opportunity, now that we have this nice new airplane, to show how to make cosmetic repairs when they are needed as well.
In doing all of the final setup for the airplane, I didn’t want to change too many things all at once since the airplane flew well in the Mirage 2000 configuration. I knew however that I did want to change out the radio. Airtronics has been my go-to radio for quite literally, decades (even had a sponsorship with them). Though a good radio, it’s a system that’s just not supported in the US anymore and frankly, SANWA/Airtronics gave up on the airplane market years ago anyway.
Well, it’s been a little while since my tease at kit bashing a Freewing Mirage into an IAI Kfir (“Kfir” is Hebrew for “Lion Cub”). We started with an assembly & flight review for the Freewing Mirage 2000 which out of the box flies awesome. However, the Kfir is such an awesome looking airplane and with canards and a little extra wing area we’ll add in the bashing process, I can only imagine that the airplane will fly even better! So, in this article, we’re covering the transformation process of turning this airplane into a Kfir and we’re using 3D printed parts as a part of that as well as employing some traditional building methods. Through this whole process we will be employing the foam refinishing method I covered in our How to Refinish a Foam Warbird series. I don’t plan to get into much detail about the foam prep work itself in this series as I want to focus on the kit bashing aspect to compliment the refinishing we did previously and use the next couple articles to go into more detail on painting, simple panel lines and weathering.
Now, one of the reasons that it’s been a little while is, in addition to of course a few distractions, is that I’ve been working out the 3D printed parts with a friend of mine. CAD modeling takes time and there were a number of parts that we ended up making. These include printing a new nose, the exhaust shroud and turkey feathers, the dorsal inlet, external wing tanks, lower ventral tank, and the afterburner cooling scoops and inlets on the fuselage. As a whole, we printed a total of 23 individual pieces for the conversion (many of the parts required multiple pieces to be printed).
As promised in my How to Repair Fiberglass and Fibgerglassed Parts article, here’s a little tutorial on some of the detail parts I had to re-scratch build while repairing my Mirage IIIRS earlier this year. These include some of the very distinctive pitot tubes and antennas that are exhibited on the nose section of the full-sized aircraft. In all the searching we did of the crash site when the airplane went in, the original parts were just nowhere to be found…a sacrifice to the three angry bushes that swallowed my airplane I suppose! Also, if you missed it, be sure to check out my coverage from the US Scale Masters Championships as I competed with my fully repaired Mirage and somehow in the process came out of the competition finishing 1st in Expert being named the Grand National Champion! What an amazing weekend! It was such a great event with a wonderful and very talented group of scale modelers, I can’t wait to go back!
CHOOSING THE RIGHT MATERIALS
When we talk about detail parts, we need to talk about materials selection. Obviously, any materials can be used, but when dealing with parts that are protruding from an airplane, we need parts with stiffness and resilience to repeated abuse. Let’s face it, these parts areContinue reading →
