Brilliant, and sounds completely realistic! Do you have a decibel meter?

Amazing....I want one. Seriously. It sounds pretty darn loud. Can't hear the blower at all when the head's going. You should build a bunch of these to sell. There's plenty of T-Bolt die-hards like me who would snatch them up fast LOL

I have an idea on how to control the chopper speed better. You can build a motor controller based around a PIC microcontroller and control the motor speed using pulse-width modulation.

A: It's very loud for its size! I was impressed when I saw it in person.
B: He is definitely not making more of these!

That sucks. I'd like to have one so bad that it's stupid :roll: Anyways, great job Eric! Can't wait to see it all done and painted up.

I don't have any problem with the chopper speed now.

I might eventually if I have some access to some machines where
I can actually work on the thing steadily instead of trying to work
in time on breaks and lunch at work.

kx250rider, there's another project of his I remember; a replica Thunderbolt he built for the Regan Library/Museum. I haven't been there myself yet but I know you live near it.
It's not a replica it's an empty Thunderbolt head with all the motors
and rotator drive removed.
Seems like all you'll need to do now is make a better blower cover, paint the blower cover and rotator box yellow, plus add a few decals.
The blower cover and finishing the rotator box is next. I finally got a new
battery for the thing and it runs like it should now.

It would be prohibitively expensive to do that. It would cost a
small fortune to build a small production run of the things. Then
to resell them I can't imagine how much they would cost a piece.

That's a great tip! I haven't been there yet either :oops: . But we keep talking about it and now I have a burning urge to go check it out... I have no excuse for not going sooner because I'm a BIG Reagan fan and as you pointed out, I can see it from here! I can see in the windows of the big building with Airforce One in it with my telescope :wink:

I'll report on it ASAP.

Yes, that's a real 500-lb Federal SD-10 I'm holding (braggart!)
