Wohoo, thanks to Steve in AZ, i have found the joy of pic hosting and i can finally post the pics of the 1st deck from my air prss and it has at last got my new Tracker race tracks on it. Its a Roarokit street kit deck, but i've given it my favorte template shape and finnished the bottom with an oak veneer, urnt in y logo and it was a jy to behold. Mabie i should have posted on homemades, but it was aways going to become a pumper and its your oppinions i'd like so,
What do ya'll think,
cheers,
Munchh.

timing system

Hey Al - for sprint runs a few of us are going in on the following setup.
1. Trakmate TIMER
http://www.infoserve.net/oss/slotcar/sports/index.htm
2. Tape SWITCHES (phone and custom order length)
http://www.tapeswitch.com/
3. About 800-1000 feet of phone CABLE for start-->finish.
Currently we're still using stopwatch and running 1. both directions, 2. multiple times (and days) and averaging, 3. throwing away lowest 'best' times since they're likely due to twitchy trigger finger. In the short term I'd recommend both you and your friend hold stopwatches, when racing try to self-time then compare against your buddy's watch.
I've also thought about setting video that shoots the whole course, then set cones that you intentionally plow through at both Start and Finish lines, to have a clear visual to double-check times later. A bit convoluted though...
The GPS will be for marathon rides. Gotta sell some stuff first!

crude but accurate timing methods?

James,
I'm just curious to know your current method of timing your races, presuming that you're not yet using the GPS systems that you talked about? My methods of calculating my times are really very crude, and I, like you, would like a more accurate method. As of now, I use a regular Casio type watch and start and stop as I'm crossing the lines. If I have a friend available, I have him walk to the finish line, while I throw down my arms while I cross the starting line. Then, of course, as I finish he stops the watch. However, with such short distances, and few seconds, I'm abit skeptical as to the accuracy of this second method. Anyway, just curious to see if we're using the same systems for timing...and if not, what you think is the most effective?

Some new unofficial TRAP times, GS boards seem to fit the pump equation! And some amateur vid:
http://home.comcast.net/~jampet99/images/trappin.wmv
Corey pumping - 15.78 mph (7.6 sec), AXE, Tracker mids, Manx 69mm.
Peters pumping- 16.21 mph (7.4 sec), PPS, splitfire, Indy offset, Avalons.
Stryker pushing - 17.39 mph (6.9 sec), mystery drop deck, Indys, Exkate wheels.

GPS on distance rides

For long rides and short sprints I'd like a GPS device, like a Garmin Foretrex, Forerunner or Magellan. there's a bunch in the $100 range, then jumps to $400 range. anyone with quick opinions would be great to hear. I see HughR uses them and mentions some issues when in canyon areas, but I suppose their accuracy is generally trusted? There must be limitations though on accuracy of really short distances. I'd like something that you can download all the ride data (altitude, distance and speed) into a PC and graph it out later...
cYa - WHEW, 12-15mph's a much better ballpark. I figured either that scooter guy was off, or else steroids were involved!! old age? no way, this stuff keeps us all young and strong!

mendicino's finest was to blame on that one
working up off of 15mph is more like it. just get one of those segways guy to ride next to you.
most of their speedometers are calibrated properly and then you can get a real good idea of actual speed.
woops! here comes old age? :D

push planks and pumpitude

Hey thanks Eric, the vids are just quickest way to share what we're up to, raw and amateur. Chaputs link is cool. Hey wait, he's just talkin, where's the riding? ;-)
77mm is a good in-between extremes size, which may apply to both push and pump times. A low, stable plank setup is the other important factor, keeping the push foot efficiently low to the ground. Didn't sense a discernable advantage yet in performance between the heavier LandyDH and lighter Rolls. Next, will be lowering the RollsRolls' CG by mounting the 77's.
I recall Chris Y's post talking about pushin' along the boardwalk at 21mph just a year ago! Hmmmmm. I'm guessing a bit of a downhill slope there??
Yep the Trap is heavily a "drill", a way to isolate specific speed elements. So at least when the subject is the Trap, its all about speed. And like I said, make it more fun...get a buddy and race it! That's the oldest game in the book -- "Hey, race you to that sign up ahead..."
For distance and just cruising, the full-on pump is what I dig. I'm not always focused on speed there, but when you've hit the same course 10 times (i.e. commute to work), you want to make that time as efficient as possible. My fastest work commute is 59mins "skumping" and 53mins pushing. For 6 mins difference I continue to work on speeding up the pump!

James the dual trap vid is awesome!
I like the pump vs. push contest, however pump vs. pump will be fun too.
I can see the genius in getting your fastest push time first. It will give you
a benchmark to beat. And you can keep fine tuning your pump technique and equipment untill you get your best time/mph. Just as you are doing for the push. It will be interesting to see what strategy, technique and equipment will produce the quickest pump times. The slalom racers are doing quite well pumping over the short 44 foot course. Presumably on slalom equipment, but their only equipment notes were; Grippins.
How did the Landyachtz DH, Exkate trucks, 77mm 81a Strikers set up feel compared to the rolls rolls with the big flywheels? Was it easier or harder to push? Faster or slower? Have you gotten a handle on what type of board/truck set up will be best for pushing 176'? What about wheel size?
Were the 77mm better than the 101mm's? Would even smaller or bigger be better yet? Or is 77mm optimum?
I realize you may not have all the answers yet. Like Erin, I'm still working on my pump. But I'm very interested in your work on pushing and I'm very
curious to see what will prevail for both pushing and pumping.
However, as Chris Y. said it's not all about speed. I really enjoy a good pump session or push cruise just for the fun of it. I see the trap as a way to find the most efficient way to pump or push.
I think in the spring I'll start timing a longer course as well as the trap.
I guess James and Al have the LDP pretty much all figured out. I'll need to work on my endurance and technique as well as equipment.
Keep up the great work everyone! This is exciting and is keeping me busy untill the weather gets better. Thank you!
-Eric

Hey Erin, I consider these pushing Trap times as a baseline for now, did it today again with an average hovering around 16.35mph, so after a few more experiments with low CG decks and wheel size, then its full-on PUMP!! And I do think the pump will take over in the longer course -- its just a matter of finding and locking in on a fast cadence pump ASAP
Today's was Landyachtz DH, Exkate trucks, 77mm 81a Strikers.
Welcome Tim! - and Happy New Year all.

James, thanks for posting that vid on your dual trap "comp". Interesting that the push is still faster than the pump! Humm, I am sort of surprised.
I am guessing that over a slightly longer distance the pump may start to gain over the push. What do you think?
I am still of the mind to use the Trap as a way of testing improvements in my pump speed and therefore will not likely mess around much with the push. Nevertheless the possibilty of either does make it more flexible in terms of have friendly competitions with other skaters who might not be very familiar/comfortable with pumping.

The DOUBLE TRAP

(24.18.nnn.nnn)
Here's a Trap vid, Munson and I hittin' it as a race this morning in a dry garage on a wet Northwest day. He pumped the distance and I pushed it. Push times were faster (7:40-7:60 range) but its just a first time trying this head to head, there's much to be explored in improving pump technique and more optimal setups.
Double Trap Race
home.comcast.net/~jampet99/images /trap.wmv
Push setup: Arbor pin, stiff trucks. 75mm 72a Avilas. (Next: harder duro and lower CG)
Pump setup: Roe/Insect 43", CarverCXs. 75mm 72a Avilas. (Next: harder duro and practice)
As a race, its a blast! Once the Trap times get narrower we'll need timing system/strips, because the manual stopwatch is hard to manage accurately at these speeds.
Munchh, hope you find a place, keep hunting! - early morning tends to be lowest bust factor. The trackers are nice, especially for the price. I like 85mm Midtracks in front.

Peters,
i've been looking, but alot of the carparks round here have that 'waffle' type concrete flooring not tarmac and i'm asuming its because we have the most 'hoodies' and we are right next to Gatwick airport, security is somewhat stepped up!
It seems to be drying up today, its been sleet for 2 days straight.
Got a bit of birthday money, went online to order those RTX/RTS Trackers ive been pining for and they are out of stock, arse, be glad to get back to work and some normality, ive put on 1/2 a stone sitting around all this time!
Happy new year all.

Al, so glad I stopped by the office for some garage cyber this morning...there was a little Xmas package waiting! Yeahhhh! I can't wait to get set up and hit some laps, that garage is saving my sanity. Munchh, can you find any indoor place to lay down some urethane?
With all the truck and deck improvements to experiment on, and workin' on both the goofy and standard pumps, I'd have to agree with what Yandall said below "...2006 could be the year of the skumper..." (Hey I'm a speed reader, I just get bits and pieces) ;-)

Those are very interesting times and observations James.
I can't wait to collect some times on various set ups. (The only reliable parking garage we have available is a midnight'er....secruity frowns on skaters ripping around in there during the day time or early evening. So needless to say this ol'gal hasn't been parkading it much lately. )
The DH I run with 180 R2's and 83 mm flywheels is actually not much heavier than your LBL pumping board, James, as this prototype speedboard has only 6 layers of maple and then a layer of carbon fibre on the bottom. A lowered board that is lightweight is just so easy to push but I still think gumballs would be faster than flys regardless of the deck. And I continue to think that pumping will be faster than pushing when all is said and done.
I can't wait to test out some of these theories..... I watch by the hour for dry pavement.....

A friend and I have been clocking the trap the last couple days, a lot more experimentation needed! After stopwatching 10+ runs manually, the range of numbers narrows down, but a timing system will be a must eventually. And yep Erin, the first thing to test will be smaller wheelsize on both pushing and pumping setups. Now I'm curious if the extra weight and momentum of the Landy DH will help or hinder... The RAIN is making this garage sprinting/timing a decent tradeoff - but can't wait to get out and just freeride some dry trails again!
JS pushing - 16.9 mph (7.1sec), lightweight drop deck, w/Exkate wheels.
JP pushing - 16.2 mph (7.4sec), rollsrolls w/Randal 150s and 101s.
JP pumping - 14.8 mph (8.1sec), LBL w/CarverCX's and 75mm Avilas.
