Sounds like a pretty good time to me [if you can keep the gates locked until either sundown or until all the fuel is gone] .

I remember looking at threads in the extreme speed forum where the discussion was about launchers for some overweight deltas that were on the market at the time and thinking to myself.........oooiiiiiinnnkkkk.......

now here is my oink-o-vator....lead sled slinger.....hoggapult.....

The next step is to rig it for a nice steady pull. I don't want the engines to die from too much acceleration, I think about 20 feet of latex tubing will do the trick. After confidence in the launches is gained, hopefully the height of this sled can be reduced. Still have to get beyond launch 1.

CP, Be on your guard if you spot even a small group of men without horses carring banners and coconut halves!

What, suction draw and carbs? No bladders? Whassup...?

Best of luck on the maiden CP, that is a seriously cool bird. I assume that once gflight tests are complete, a pair of piped CS's are going in their place. I'm leaving tomorrow (Thurs latest) for Denver on a road trip to pick up an airplane, I bet the succesful first flight report will be all over here by then. 1600 miles each way in a '77 GMC Gaucho shaggin' wagon. We thought of sticking flowers all over it, but those sorts of things tend to alert the border patrol that a cavity search might be in order. Somebody actually said "peace" to us a couple of days ago.. yikes. Maybe I can watch the flight video on YouTube in my cell, if Bubba lets me at the keyboard.

Status: online 		MJD, it's been too long since I used a high start, but if memory serves correct they used about 20 feet of latex tubing that got stretched out........I'm going to say 4 times original length? I was always impressed with those glider launches with the gradual pull. IIRC the tubing was about 3/8" diameter?
Have a nice trip to Colorado, that's my favorite place inland. Drive to the highest place you can find, then chug a couple of beers real fast.

Bin dere, done dat... at least as far as I can remember! I had a brief sebatical from Canada and lived in Co Springs for 3-4 years circa '89-'93. Cheyenne mountain was visible out the bedroom window, I was always waiting for the 1ms flash then - raster lines -. Once a young lady who was acquainted with my wife and I wanteed to take a trip, so she flew down to visit. Nice girl, but she was pushing 300 pounds. We still drove my wife's old Nissan Pulsar, and she wanted to go to Pike's Peak (14k). Well, we got to about 9k then vapor locked, I guess it was heating up too much under the load, it made it with the two of us fine before.. so we apologized, blamed it on the car, and turned back down.

Yeah, hi-starting is indeed a riot. The tubing varied in diameter depending on the weight range of the glider for which it was intended. Latex typically maxes out at about 7x AFAIK. There was more than 20', not sure how much, not a whole lot more, maybe twice that, I can't recall - mine rotted and got tossed, I use my buddy's whenever I need to, but mostly I tug (gliders that is). Sometimes it seemed like it was never stretched enough. It also seemed like it took a whole day to roll it up again when you were done for the day.

Should be a fun trip, two middle age ex-st disturbers in a hippie van for 60 hours round trip. We bought a nearly complete Pietenpol, got an engine waiting here for it. Putt putt putt.. good fun. You can get these things way cheaper than I ever imagined.

so at least he will get a lunch along with a tentpeg to the face

Status: online 		You guys forget that I'm an electrician...I have to drive into the ground a pair of 10 foot ground rods next to every service panel.. ..for this contraption there will have to be stakes driven all over the place to secure the framework, too. I've got a bunch of rebar and will make some 18 inch long stakes.
MJD, I lived in a barracks in the shadow of Cheyenne Mountain 1975-77. The most irritating thing to try to do there was sun bathe, one minute you would be roasting, the next you could have snow flakes, 5 minutes later back to roasting again. It snowed in Colorado Springs on the 4th of July in 1976 after being in the 70s most of the day.
Your aeroplane sounds like a lot of fun, but uhh...once a plane gets past about 100 years old shouldn't it be retired?
