By the way, I just talked with Mike Fisher about doing a fully-glassed Lightning Bolt with a 75mm motor mount sometime...

I have a 54mm version of that kit that I was thinking of giving a fiberglass wrap. On the other hand, there's something to be sad for keeping it lightweight. Gives me a lot wider range of motors to fly it on.

True! A glassed 75mm bird would probably have to stay in the K-L-M impulse range.

Altitude was reported as 4,568 by the Eggtimer

Pretty good altitude for a 4" kit on a mid J and dual deploy. I once flew one of our 4" kits to 8K' on a J570. IIRC, it was built with wood glue and I left off the bay kit to keep it light.

Depends on how much glass you use. A J350 or J570 would lift it if you didn't go crazy with the layer thickness. When I get time, I plan on building a 75mm all paper/wood glue build and put it up on a long burn M. Just lined with our new HD couplers should be plenty strong enough, with the 12 ply 1/4" fins it should hold together just fine.

Gotcha. Your project sounds WAY cool...

Flew on a K805G at about 10:00 on Saturday morning.

Very nice and informative build, I enjoyed following along,,, Nice flight as well.

Could you please give me some info on the pad base you launched from? Looks to be gray PVC which I can see ok but what I'm interested in is the top portion where the rail is attached. I'm building a similar one and would like to see how the one you used is attached, if you can of course.

Thanks
Ed

It's a quad pod. I don't know if they make them anymore. Used to be a real popular design. I've smashed a few.

Hi Ed, thank you! Yes, as Mike said, the pad head is called a Quad Pod and I think they were manufactured by Black Sky? Not sure if they are still made, either. Our club has probably about 9 of them and they are our standard for high power pads.

I've smashed a few.

I heard about that...

Thanks guys I think I can do it with the pictures I found.
The PVC part is no problem just need the parts on top to attached the rail to.

It is a cast piece with a turnbuckle adjustment for angle and a locking pin for tilt down loading.

Here are some pics of the pads in question. I cropped them down to focus on the pads.








Hope it helps.

I think I got an idea from what you guys posted so off to the hardware store.

Thanks

Good luck - and please let us know how it goes!

 

[race 58]

I will.
Thanks

One of our members donated an old Quad Pod to the club - a version with a particularly puny aluminum tripod-like base. We pitched the old base, and Grimracer designed a new, tubular steel base for that great Quad Pod head. A bit of expert machining, welding, and powder coat, and we've got a great HPR pad with a stable base and versatile head. I'd like to find more of the old Quad Pods and convert them, too!

Looks good! Our club has a more "robust" version of a Quad Pod as well that is primarily used at the away cell for "hard-hitting L's" as well as M's. It too is powder-coated and was designed (I think) by a club member many years ago.
