That would be fairly standard for any battery. They work on chemical reactions. Chemical reactions need heat. Not sure if I would go as far as a freezer, but maybe the refrigerator. Race them hot, store them cold. Gene

Ooops. That was me above. ...... we need a big banner that screams, "YOU ARE NOT LOGGED IN!!!" Gene

Ok,... so we've established that the weights of the electrics and nitros are about the same... and that the HP is pretty close too. ..... and that electric is actually running smaller props, not larger. .... and that diameter doesn't neccesarily mean speed. Now,... we know that no...

According to my receipt, it's: [email protected] I could've sworn it looked like his normal one(the one in his profile) before, but I may be remembering wrong. I'd go with the one above. He should be able to get it either way. Gene

Nice graphs. Definitely need the larger cells I guess. Those 17s and 19s drop a bit too quick. I'm running a fairly hot modified right now, so I'm probably pulling close to that. Thanks for the info. Gene

I'm still quite a fan of gear boxes too. For the average boater, they're probably not any good, but for someone who works their props a little, I think you have an advantage. The average props favor high rpm. Till handling problems develop, I think it's better to go down in rpm and up in...

I don't know if mine was the first twelve, but if it was, I really don't have anything to advertise. To open that spot(maybe others) for companies to sponsor, maybe we could give it to the highest bidder? Highest bid gets it, and that money goes to the kitty(to the treasurer). If we get too...

I don't have any mono's, but double tabs are better. That way you can adjust the inner tabs for straightaways, and the outer tabs for when the boat leans into a turn. That of course is assuming that your boat has enough of a V for the edges to come out of the water. If they're alwys in the water...

My guess to the question above is maybe 35amps? Was noticing the 2600 NiMH graphs on your site. Those hold up quite well at high amps for NiMH! Nice and light too. I'm running an 05 right now, so lightness counts more than super high amps. Maybe I will buy some cells soon. My cp1700s are quite...

I'd like to know just how hard the cp1700's can be pulled.......say to where you can get 1v for most of the run? Also 1950's. How many amps does it take to get them down to 1v? Gene

Just a couple more thoughts....... Someone either here or another forum mentioned that some speed records are set with stock engines. Also, I remember when I had a 3.5cc outboard, that the stock class had an oval record over 50mph(I think). So what's the difference between a stock engine and a...

Mike, 700 motors aren't really a comparison with brushless unless you're running enduro. For the sprint classes, the proper motors to be competitive would be Megas, Pletts, and Astros. The 700's wouldn't be competitive in a sprint class even if it was all brushed. I think Andrew was counting...

Sticker shipping: $$ ? Tom Moorehouse database programming @ $100/hr : Way more than what you have left over. Keep the change. That's your labor cost. If you don't want to charge us for that, then consider it a Christmas present. Gene

Yeah, I used to be the type to throw tons of cells in a boat, but now I find I like to tweak the little things to get to the same speeds. I have been very impressed with my four cell. Not quite as fast, but just as much fun as my 18-24cell boats were. Gene

Guess it was really meant as a beginner's class. If find it really fun though. Fairly high speeds, and you only have 4 cells to tweak. I have thought of getting a LM Neo can, or trying to make my own BL controller. I haven't researched that yet. Maybe since it's not popular in ovals, they could...

Maybe since Andy K is hinting about a 32cell BL controller, you can hit him up for a 4cell with BEC. The hard part is they usually run off microcontrollers. Those normally require 5v or so. That means you have to include a voltage doubler or something. Andy does it with his brushed controllers...

Hmmmm,,.... down here we don't have time to build boats in the winter. Our boating season is all year! ;D Just thought I'd rub that in a little. I have found me some semi-lighted sights to run at after work. On another note, I think I'll stop procrastinating about building an Oh Boy Oberto...

more rpms= higher water speed exiting the prop more pitch= higher water speed exiting the prop Since our rpms can go so high, we can use a smallish prop to occomplish the same thing. Since ya'll have lower rpms, you need to make up for it in pitch. Thus, you're back to trying to launch a high...

Ian,... yeah, I understand the hp curve. Just didn't seem to me that they had much problem at the low end for SAWs. That's the best thing about electrics..... we have all the low end, so we can pull as big a prop as we dare, and won't have a problem getting it on plane. But for the high end, we...
