is the MARS M2 in anyway related to the original MARS unit designed(for the military i think) and sold sold by Steve Snyder/SSE Inc in the 90's??
-
years ago Bill Booth made a statement about the bridle stow on the wonderhog. it went something like " because it exists ,it can fail" i tend to apply that statement in this situation also.

x connectors were required on all chest packs in case one snap detached from the d ring

when i worked at para flite in the 70's and 80's, the links were turned with the barrels inboard so that the slider would not whack into the barrel. since para flite was the First to use rapide links,you can take this as gospel, no b.s. FOR THE RECORD, this was before slider bumpers(which para flite also introduced in 1978 on the safety flyer ,the first square reserve)

the stimpson tools work very well for setting grommets because the grommets were made by stimpson. if you compare the stimpson tool to the cheaper osborne tool you will see quite a lot of difference in the actual shape of the die. when Para Flite designed th swift system back in the 80's they used aluminum grommets ,but had major problems with them splitting. Manley Butler consulted with Stimpson and had a "coiling area " machined into the tool. this allows the grommet edge to roll instead of just smashing it over.

LOL most of these guys probably dont have a clue what a dot snap is

back in the late 70's Para Flite had the Cruisair, but was forced under threat of a lawsuit from a Motorhome mfr. to change the name so when they switched to F111 and i beam construction(circa 1981) it became the Cruislite. true story i worked ther at the time

Palmdale California should have received one .after all they were all built and serviced (for a period) there.I understand that Rapter actually worked on the avionics
-
if the calibration knob is stiff on an altimaster 2 it is not the O ring at fault. the gear that is pressed on to the knob may have been forced too far onto theknob shaft. however tighter is FAR better than loose,because it is less likely to move the needle if you accidently bump the knob in the aircraft(thus giving a faulty reading)

thanks . i didnt know that.but it makes sense.

is there any differance between regular medical oxygen and aviation oxygen??

i built a bi plane canopy for Steve Snyder in 1988. it was an idea he had for easily increasing payload on para point delivery systems.. packing wasnt all that bad,just propack one canopy at a time.since we actually had one that was a in use i would imagine ol snydly went ahead and patented the idea.

make sure you are using bonded thread. unbonded thread will quickly skiev and break after just a few stitches

he is flying a sailplane, a Kestral(sp), airspeed of 155 mph. he was using a security 150 in it so anything similar in size would work for him .BUT he is 240 lbs without a parachute so i need something that he would still not exceed the weight limit. also he is a little concerned about rate of descent at his weight
-
i just took a security 150 out of service that a customer brought me for repack(it was last packed in 1983!).this guy is 240 lbs without a rig. i need a suitable replacement rig for this guy.anyone have something for sale that would work at his weight?

when i worked for SSE/ParaFlite, there was an incident exactly like you described in inccident#1. investigation turned up witnessesthat saw the jumper calibrate his unit IN the aircraft instead of on the ground.

the idea of using a pilotchute with a sentinel came about after a fatality t snyders dropzone of a first jump student(she pushed off the strut,went onto her back and as the pilotchute wasdeploying between her feet she trapped it.continued to fall back to earth ,sentinal fired but without a pilotchute, it did not start deploying until about 200 ft,(too low for sure). the next weekend snyder and elek puskas sat down with all thier instructor/jm's and had an all day discussion about it.the concensus was that a student who was "out of it" likely would not be throwing a reserve if they didnt pull it either.so pilotchutes became the norm on all his student reserves and a recommendation was put in the manual as well.
-
yes ,the original Sentinal by steve Snyder

photo is a FAKE. i remember seeing it in lyle camerons rag if i recall ina tongue in cheek article called loop the commander

actually i have seen 2 instances where the outcome would have/could have been fatal. the first was a round reserve that had been severly damaged by a hot knife. the rig came into my loft packed and sealed. there was no damage to the container but about 8 or 9 panels were full of melted holes that i can only describe as HUGE(with partially severed radial tapes.).and they were in the high pressure area. the second was a 26 ft navy conical that had been used for like a hundred jumps as a main,and someone had put it in service as a reserve. when i did the old strength test panels just ripped very easily at about 5 to 10 pounds. out of the 88 panels in the canopy 28 were weak enough to rip by hand.the owner was a big boy too at about 225lbs. so my guess is he would probably have been severely if not fattlly injured.

it wasnt bill booth who coined the term" breakaway." it has been around almost as long as 1 1/2 shot capewells(like since 1964 or so) have been used on sport rigs. but the term cutaway is still the common coloquialism(sp)

the opening will probably knock your socks off
