New R/C Speed Record!

[Fluid]

The JAGs team from Germany set a new speed record for R/C boats today - a two-way average of 140.9 mph at the LA SAWs. It was with a 32-cell outrigger of novel design, similar to what the team has run in the past. What an accomplishment!

The power of the new IB4200 cells they ran is significantly greater than that of the old 3300 through 3700 cells. I changed out the twelve 3600s in my SAW cat for IB4200s and increased my speed by 10 mph - no other changes. :eek:

Where can you get IB cells?

[BoatDoc]

they are very good cells. i've been using them all year in my N-2 mono and it's a good scooter. i wish i would have run them in LSH because a little extra edge in that class goes a long way. i got my 4200's from offshoreelectrics.com. also check out cheapbatterypacks.com

They are what I was going to go with for the comming season. BUT..... I have been advised by more than one person to hold off because of a posible rule change....and introduction of lipolly cells.

I heard that there was another record set, a hydro, not a 'rigger, broke the 100 MPH barrier, the first electric non-outrigger to do it. It was one of Brian Blazer's Sport 20 kits with 28 cells aboard.

[BoatDoc]

8 cell riggers are up there too, can't remember what the new record is, but i heard that there were some 100mph passes made.

[Fluid]

Brian Buaas made a single pass at slightly over 100 mph, becoming the first R/C boater to make a pass over 100 mph in a non-rigger. His boat used 18 cells and a Neu motor; it crashed after the 100 mph pass and was damaged too badly to be repaired at the event. I did see his pass at 98 mph - the boat crashed then too, but wasn't damaged. Pretty good for a wooden boat!

Two 8-cell riggers ran over 100 mph, the new record is just under 101. A six cell rigger set a record at near 93 mph. It's hard to see those small boats at that speed!

I'm a little confused at what "IB" cells are. Are these the Intellect cells? or are they a certain type of Intellect cell? I have a 7-cell 3600 pack of Intellect cells but the letters "IB" don't appear anywhere on them.

[Fluid]

The IB4200s are from Intellect, but the hot ones are the 4200SHV and 4200WC.....or so they say. I'm not certain there is any difference between those two cells other than the wrapers. :confused:

according to the mfg, the WC cells are supposed to have a better voltage under load than the SHV's. then again, a lot of that stuff is marketed towards the car market, and they'll pay anything for "the latest and greatest" even if it offers no real advantage. for proof of that statment, go to your nearest LHS and have a look at the $10 cells they have. sorry, but i'm not paying $10 for any cell, ever again, it could be made with super-special-high voltage uranium from mars, and i'm not going to buy it!!!!!! if it's not matched or zapped or rolled on the thighs of young local women, it ain't worth it. you can get IB4200's from offshorelectrics.com for under $6 each, and they'll do the job. i ran them all year in my N2 mono, and they never failed me (they were unmatched, unzapped, and never rolled on anyone's thighs).

and never rolled on anyone's thighs LOL

[BoatDoc]

steve, i know you do a lot of testing. have you run your out-of-the box cells against the matched/zapped cells? i know that i've decided not to spend my money on matched cells anymore, the plain ones are giving me all the performance i need.

[GregS]

I've heard the IB4200's have quality issues but that doesn't seem to be your experience.

[Pagemaster]

Matched cells will have the performance edge. But in a boat on a oval course I don't believe there is enough of a advantage to pay the extra. But for a saw event where event last volt counts and the race is over in a second I would say buy the best you can afford.

that makes a lot of sense, steve. maybe with LiPo on the horizon, it'll be a thing of the past anyway. can't wait for my new 2s lipo mono :D the saw guys have to break out all of the tricks to set records these days. i'd like to make it to a SAW event one of these days....i've gotta see these 100+mph 8 cell boats :eek: not sure if i can make one next year yet, i'm still planning a trip to AZ for the winter warm ups, and that's going to take a huge bite out of my budget.

[Pagemaster]

it'll be a thing of the past anyway. can't wait for my new 2s lipo mono
Be careful what you wish for! The best lipo cells make those "pushed, rubbed, touched, zapped, matched Nimh cells" look cheap! :) And we all know the argument that the lipo packs will last for several seasons. But at the rate the lipo cells are advancing the latest and greatest lipo cell this season, will be old news and out dated for the next season. Its going to cost a bunch to stay on top.

[BoatDoc]

i hear ya! hopefully the cost of these things will come under control. only time will tell, i guess.

[SouthJersey-FE]

Well just let up hope that rules are created and implemented that keep costs under control. In my opinion if rules are changed and the new cells are made legal. A structured class system should be put in place just for them. This would allow people to choose if they want to make the investment. Personally to make it less confusing I would suggest not using them in M-2 or N-1(to keep costs down) and just leave the remainder alone with the exception of adding an L to the class for lipos. For example you would have N-2 and N-2-L. Now you have a choice. If they open it up with no restrictions you may as well toss the Nihm stuff in the trash(along with your budget). So can the vendors because prices will have to be dropped on them to make sales.

[BoatDoc]

we've been going through this talk most of the year. it's funny sometimes, but even though most guys want to make the switch, no one can agree with anyone else on how to do it. do we allow unlimited paralleling of cells? do we let them run with NiMh's? do we set up hull limits? do we run voltage classes (allowing any chemistry)? and it goes on and on from there. this next race season is going to be interesting as we get it all sorted out. i wouldn't be surprised to see a vote this time next year to tweak the rules a little bit. one thing most people agree on, is not running mixed chemistry classes. that's been done at a few races already (mostly in offshore) and the lipo boats have a clear advantage. i say bring it on, we'll fix it as we go.

[SouthJersey-FE]

I would agree with making them legal. For me its not a problem because I am just starting out. I have no investment in Nihm packs for racing. So im just going to buy all li-polly stuff on the outset. I just feel for the guys who have the big money nhim stuff allready. But I guess that why god invented ebay. A 50 to 65% return on them is better than the garbage can I guess. As soon as OffShore starts stocking them I'll be abuyin them. Yeehaaa

The sport hydro was a Blazer Marine Whiplash 20 running a Neu 1521 on 18 cells. It hasn't officially been over 100 mph. The complete pass was recorded at 98.1mph tumbling through the traps for the last 30 feet. The boat is repairable and will be back with a couple minor geometry changes.

Mike Bontoft has made a one way pass with a gas sport boat at 102mph I believe.

The new O hydro record is 98.77mph set by Arne Hold. Both runs were at 98.xx MPH. I had a one way pass at 100.9 mph (the only 100+ 8 cell run to date) but the ESC thermaled on the backup (sucks to be running off the shelf equipment).

As for LiPos, bring em on. I'm tired of NiMH. Anybody interested in some slightly used IB4200WC cells, they only have about 10 passes on them :D
