Thanks Xviper! Just listed this project for sale here if anyone is interested: https://www.rcgroups.com/forums/show...design-Project

You made a tremendous effort at a time when it was so needed. You should be applauded for it. I almost went your route myself, but then, it involved Banana Hobby, so it never happened.

Sometimes a project sits on the shelf too long… Looks like Freewing beat me to the finish line. Just preordered their B-2. If anyone is interested in the guts of this project, let me know.

That's no excuse. Chop! Chop!

Any updates? This was an awesome project.

It’s still happening, but it’s on the back burner now. I bought a house, moved, and had a lot of travel for work. My time for projects has been pretty limited these last few months.

[Aros]

I concur!

I remember my LX F-117 years ago...Bone stock...Was a slug in the air but I recall it flew decent. Tons of drag.

That’s awesome I’ve always thought that would actually fly really good. I would guess it feels like a race wing with really bad drag.

This project is absolutely amazing to me. Maybe you should tackle the LX SR-71 in the future or the F117😱 always wanted a flying cheese wedge

I actually tackled the F-117 already, and it’s a surprisingly good flyer when setup correctly! It’s on the bench right now due to a dead aileron servo, but it is very well behaved in the air. Flies similarly to a pop wing with a giant speed brake on it :). I switched out the power system for an FMS 12 blade 4S fan, added spars, electric retracts, shock struts, and sequenced gear doors.

Aros, I can only hope it turns out as well as the B-25 did! This one definitely has a few extra layers of complication though!

Trust I have in you.

F106DeltaDart, 90% IPA will dissolve most acrylic paint. I used that to remove all the paint from my F-4 canopy and re-masked the for a more accurate canopy frame and window shapes. Could you do that for this? Best, LB

Thanks for tip Elbee, I’ll give that a try!

Michael, this is going to be a fantastic update on the old LX model. Watching closely.

Thanks Tom!

One of the next things I need to tackle is reinforcement for the center section. With the battery bay, bomb bay, gear bays, and ducting, space to run a spar is near non-existant. What I will most likely end up doing is getting some 1.5-2mm carbon sheets water jet cut to reach around these. Ideally, these frame could also tie into the main gear mounts.

If it turns out anything like his LX B-25 we will be amply rewarded.

Not much progress today, but I’ve been messing with tape to see what it will take to get the windshield looking a bit more scale. There is definitely an improvement by altering the shape of the windows, but the angle of side braces really bothers me. It gives the side windows quite a different look than the real thing. I’m also not a fan of the thick raised canopy frames. The real frames are perfectly flush to avoid radar returns. For now, I’ll probably just modify the stock one a bit, but if I can get it flying well, I might end up making a new windshield from the start.

Quick update for today. Sanded down the filler and shot a quick coat of primer over it. Very happy with how the modified intakes are looking so far. Will still need a few rounds of filler, primer, and sanding before it is smooth.

This is a great project, and it is looking spectacular. It is already SO much better than LX designed it.
