I was told last night by Kim that the NAMBA Sanctioned Fall Straight-Line (SAW) event, originally scheduled for October 19/20, has been rescheduled to
November 8, 9, and 10th
.
 
The NAMBA and D19 websites are still showing the old dates, and I've requested that this get updated, but in the meantime, make sure you note this date change and spread the word.
 
Please contact Mark and Kim Grim if you have any questions:
[email protected]
 
Hope to see you all there!
 
I just got a notification from Robert Holland that the NAMBA and D19 websites have been updated to reflect the correct November dates.

See you there!
 
Guys, It's getting close to the event and Mark and Kim need a head count particularly for food. If you have not been to a Legg Lake SAW in recent years, Kim Grim rolls out the red carpet with a 5 star BBQ buffet. We want to make sure we have enough food to feed all those that attend. Please email Kim and Mark at [email protected] and/or post here and I can relay a head count.

Earlier repost:

The Fall time trial has been moved from October to November 8th, 9th and 10th. Come out and participate at the premier SAW venue held at Legg Lake in South El Monte, CA. The three day event will run from sun up to sun down and is topped off by a gut busting BBQ extravaganza by Kim Grim. We encourage all to come and participate whether you are a seasoned pro or a first time SAW racer. We welcome all international competitors and can assist with equipment and shipping to make travel a bit easier.

If you know or think you can make it, please send Mark Grim an email or phone call so we can get a headcount.

Remember NAMBA has just approved the new Cat classes so there are open records to chase. If you have any questions post here or contact Mark.

If you all would quit scheduling these on the same weekend as out 2 lap events I would come down.

I hope you guys have good weather (no wind) down there.
 
This is going to be a great event particularly if the weather holds. I expect we will have 6-8 boats consistently running over 100 mph and several should be near the high water mark set by Joerg.

I managed to get all my boats prepped over the weekend and a reasonable kit of spares amassed for the inevitable.

I will be out at the lake around 5AM Friday to start setting up signage and safety lines to keep spectators at a safe distance.

Just a reminder, every competitor should have a fire extinguisher and have safe charging practices in place. We don't want to see anyone overcharging, over cooking or generally taking unnecessary risks. Also make sure your boats are legal, this includes NAMBA numbers and applicable rules for certain classes. We will have a short drivers meeting Friday morning to review the procedures as I know several new faces will be at the lake. I am going to also ask every competitor to grab a spotter/caller before their run to have an extra set of eyes for safety. There will be plenty of us available to assist.

See you guys at the lake!

Here are the official results of the recent SAW event at Legg lake. Congrats to all those who posted new records and thanks to everyone for making this a safe and always fun event. If you were not there you really missed out on some great water and even better food. I'll follow up with some reflections in another post.

Fastest one way pass was a 135.679 in T Hydro over Brian Neal's 135.460 in T Cat.
Other notable speeds: Mark Grim went 109.4 with his G2 hydro, Steve O'Donnell ran 101 mph with his A hydro, Darin ran a little over 70 mph with a one cell M2 hydro.

Still working on recovering from 20-hours of driving home from this event, but already working on plans for the next opportunity to do this again!

First, I'd like to thank Mark and Kim Grim for all the time and effort and energy they put into these events. It wouldn't happen without them and their efforts are very much appreciated by those of us who LOVE to do this. Also, thank you to Mark and Kim for putting me up for the weekend! Brian and I had some last minute change of plans that made it necessary for me to stay with Mark and Kim, and it was a very comfortable stay! Thank you, Grims!!

Thanks to Tyler for putting so much time into the details of the event, especially the safety barriers and signage and also the improved teching and record keeping. Seems to be getting better all the time and it was NO small effort to do all of this, AND prep boats to go well into the 130's. Thank you, Tyler!

Thanks to Tony Heller and all of the gang down there that took their own time during the week to go prepare the sight. They cut back the shoreline reeds that seem to be taking over and totally prepped the site for this event. NO small task! Thank You, Gang!!

And we can't forget to single out Kim Grim for her AWESOME, as usual, Lunch cooking, which is an event all unto itself! That alone is worth the trip.

Probably more I should be thanking, but they are giving me the cue to cut it short... ;)

I had a great time, despite doing some pretty major damage to my Lynx during a P-Ltd OPC record attempt. After having blown it over on a few previous attempts, and having already made a couple of successful 65mph test passes, I was getting very close to the right setup. On Friday evening, I put the boat in the water and was making a first pass. The boat took a BEAUTIFUL set and looked to be heading for half of a quality record setting run. I was focusing on the hull, watching to see what it was going to do as it approached those magic numbers. Unfortunately, this means I wasn't watching it's line as carefully as I normally would, and I got a LOT too close to some overhanging bushes on the back side of the Legg Lake course... The damage was not too terrible, considering how hard it hit, but the impact did tear off my outdrive, sending it to live with the crawfish at the bottom of the pond... Gotta give Fred a call today and order a new one. I talked to Carl on the way home Monday and after seeing the pictures, he thinks I can repair it and it should run right again. Breaks my heart that this happens (this is my all time favorite RC boat!), but this happens from time to time. Will repair it and move on!

So, having brought two other boats, I turned my attention to running my N2 Catamaran. Made a few quality passes as I was getting the ride attitude and setup working. Went for it on Saturday and made a pair of 65.xx mph passes, which simply established a new N2 Cat record. Since the class didn't exist prior to this event, I was the "record" holder by default. Boyd made a couple of passes with is N2 Cat, but it wasn't really setup so nothing spectacular there, and he was focused on much bigger stuff, so at this point, that record stands. I did put in a different setup later in the day, which should have put me into the 70's, but a failure of the speed control on the way out to make the attempt burned the inside of the boat up pretty badly. The ESC failure cause was figured out on Monday on the way home, (we had two of these fail this way this weeekend), and it was NOT something that WE did. More on that another time, but I would attempt with that setup again in a heartbeat once the ESC issue is resolved. This record is VERY soft, and should be closer to 80mph, so it's a record, but a pretty soft one. I will likely be going for this one again at future events.

SO, that left me with ONE boat to run... My M2 Hydro (M2 = 1 cell, ANY motor)... In previous SAWs, I've tried this and the best I've been able to achieve was 68mph on one pass. That happened rarely, with 65-66 being the norm. The record is 71.xxx, set by Bill Oxidean, who has only achieved those speeds once himself.

Well, after having about the same luck with my M2 Hydro on Saturday, I decided to make some major changes. Changed ESCs, and started playing with it on Sunday. The new ESC was showing a LOT of promise, so I started playing with props. Changed props and went out in a tad questionable conditions, which for this tiny little rigger means pretty much anything other than pefect glass. Ripped off a 70, 72, and 71mph pass! This was the norm for the passes I made the rest of the day!! I missed the record run by just a few tenths, but I was now consistently in the 70's! On ONE CELL!! Pretty cool stuff (for me, anyhow). As Sunday wained on, I starting the prep work for that ONE final set of passes that would net me the record.

Unfortunately, after an entire weekend of REALLY good water ALL DAY, about 2pm on Sunday afternoon, the conditions INSTANTLY changed! Wind picked up. Mark Grim said that the humidity went from 20% to over 40% in a matter of minutes, and basically, the day was over. Blew right up until sunset.

I did get ONE final set of passes, almost completely void of light! I couldn't even see the boat for the return pass, other than a slight ripple in the water as I tried to line it up for the return pass. Got a 71 backed up with a 69, and it was over. Will have to wait until the next time, but I'm FIRED UP to build a new M2 Hydro boat. What blast to do that on 1-cell! Definitely not an easy feat.

Well... that's part of my story from this event. Much more to tell.

Thanks again to all of those that helped make this event happen! I look very much forward to the next time we get to do this!

Here are a couple of pics of the damage to my stuff.... Hopefully Tyler or Tony or ?? will post some more fun pics of stuff actually running and looking good! B)
 
Man...20 hours! Wow, and I thought I drove along was after my 13 hour drive to North Carolina. Darin I hate you didn't get to finish that run. That single cell run you made was unreal!!! Great job!

I wasn't at the event but want to thank Tyler and the Grim's for taking safety seriously. Good job to all at the event.

I was hoping that this was the year both for Joerg's 140 mph electric hydro and Mike Bontoft's 109 mph gas rigger record to fall. It looks like it's tough to get two passes back to back at these speeds.

Darren, you should write up the event for the Propwash.

It was tough trying to keep propeller blades attached to the hub or we would have broken the record. I broke/lost 10-12 props, went through 8 drivelines as a result of the props breaking and totaled a boat on the maiden pass when the rudder broke. The 135 pass was made with the smallest prop we prepped, but any larger diameter and the blades just flew off.

I 'm working on it today.

Hi,

with high power electric DrivesHi you need much stronger propellerblade design as i attached in the pic .

This Prop withstand highest torque during accleration on a Scorpion 5030 turning up to 30000 rpm . And the best it took less power belong to the lower pitch ABC Propeller same dia and result on higher topspeed.

How about cast chrome cobalt?

124,000 psi tensile

80,000 psi yield

29 x 10^6 modulus of elasticity

Or machined A2 tool steel

over 200,000 psi tensile

29 x 10 ^6 modulus of elasticity

Compared to cast berylium copper

maybe 140,000 psi tensile if hardened

18 x 10^6 modulus of elasticity

The both chrome cobalt and steel are a lot stiffer. Cast chrome cobalt has already been used for very high quality props (I just ran one) and can be easily investment cast by many local labs using very high quality equipment that will maintain the properties. Tool steel props would need to be machined and heat treated. Steels have the potential to make the thinnest props. We used hardened steel for rudder blades. The thickness change was good for around 6 mph at 100 mph.

Lohring Miller
 
Lohring,

The A2 tool steel would of course be the best or a 17-4 H900 SS. The cast CrCo will be the next step in till I can model the props in SW and then have some CNC'ed and heat treated. I sent you an email about the prop you have in CAD.
