Here is a shot of Clint Brooks holding his latest proof build
BOOMER MK-II. The picture was taken at the Dog Park in Costa Mesa
California a couple of weeks ago. The model has been set up with the Gizmo-Geezer front
end. Model as built per kit comes in at 37.7 grams without rubber. Stab and fin are tissue over mylar-the wing is tissue only.

via email from George Nunez:
A few words from this weekend's flying at
the Dixie Nats in Palm Bay FL (with my BOOMER) Windy, muggy
and hot weather but we decided to go anyway. Without rubber
but ready to fly plane 34g 4 strands of 3/16 10 g motor. A
little tight but after a few stretches it freewheels OK.
Test glide looks very good First flight 300 turns, goes
straight and a few deep stalls. Did not get to glide. I sand
in some down and right ( more right than down ) give it 400 turns
and it went like gang busters, it got some nice altitude
settled in a nice glide but then got some good air and it started
going up real fast. I estimate it got to more than double
the altitude when the motor run ended. I had a two minute DT
and I got it back. Almost lost it on its second
flight. People asked if it was a Sparrowhawk, heheh (not so,
it's a CB Model Designs BOOMER!).....You got a terrific performer.
Cheers,
George Nunez

My Boomer has finally had its maiden flight today, one year later. :-)
The building process was smooth and pleasant. The wing looked scarily complex but turned out to be straight and rigid -- all those little
gussets and reinforcements must have helped keeping the warps
away. During building, I kept referencing to both the rev-a and rev-b manuals, which I had downloaded from your web site. While rev-b is up to date, rev-a has some helpful pictures in it.
Covering the undercamber with tissues was frustrating. I had to constantly reassure myself that the plane would fly so high that nobody would see the wrinkles.
Indeed the Boomer flew high today. The final flight (with 1000 turns in the rubber motor) lasts about 2 minutes. Now it is a matter of trimming and trimming...
I had some previous experiences with the button timer from A2Z Corp (Peck-Polymers, Sting Aero, etc.), but could never get it work predictably, so this time, as shown in the attached picture, I use a ParkZone Vapor brick for DT. The radio seems to have a good range while the plane is in the air, but there was one time, after the plane had landed, the receiver lost signal, fail-safe kicked in, popped the DT. (Well, at least I got the assurance that fail-safe worked.) The 1-cell lipo battery lasted the whole morning
Thank you for having designed such a great flier. Wow.
