RE: Central NEW YORK boaters
ORIGINAL: engineman351 I stole most of this off an e-airplane site: The ''C'' rating tells you how much current it is safe to draw from your battery. It's expressed in terms of the capacity C. So a 1200mAh 10C battery is good for 12A (10 x 1200mA/1000) and the same size 12C battery would be good for 14.4A (12 x 1200mA/1000). An example: One battery is 900mAh and 10C so it is good for a 9A draw. A second battery is a bit smaller at 850mAh but higher rated at 12C so it's good for a 10.2A draw. You can plug in the numbers for whatever pack you are using to see how many amps you can potentially draw. The C rating doesn't mean your motor will go faster or run for longer. It just means that if you ever want to use more current, by using the battery with a different motor or a bigger prop, the 12C battery will allow more than the 10C version. Furthermore most RC’ers treat the ‘C’ rating as a ‘burst’ or max amp draw situation…but to know how close you are actually getting to the ‘burst’ level, you need some form of a ‘Watt Meter’ to really understand what is happening in your set-up. My rule of thumb is: The higher the ‘C’ rating the less chance there is of exceeding the battery’s capacity to give up current and not hurt your battery. Anyway...my 2 cents (again!!) Roger |

Roger I am good for 100 amps, 25 x 4.0 ah. The Dynatron starter is rated for 100 amps, so you are good to go. Roger, Good info!! Thanks! |

I meant Pete in Elmira.
Yes, I will call you when we go there. We will be running our 72 inch vee soon, and I need a large area... Joe |
RE: Central NEW YORK boaters
72 inch V ..........u kiddin me? is this another one of your mega machines or will this reach production someday?
tell me its a turbine please..........i gotta see this! |

RE: Central NEW YORK boaters
If all goes well, I'll be running my .12 Zippkit rigger for the first time this Sunday afternoon! :)
Let me know if anyone else wants to run on Sunday afternoon. |
RE: Central NEW YORK boaters
Rigger Sunday will be a good one.12:00 12:30 is fine for me. My .12 carb has the mods that Glenn mentions Low speed needle is flush with the carbs inside wall. And the brass carb pipe modified. Looking at a few of my older carbs the brass fuel pipe cuts are all facing down. My .12 NR isn't starting. Looks like no compression. The .18 Go has no waterlines as that water jacket is very heavy and big. I added the .12 NR air fin-ed head. Will it over heat !!!!! Bob .18 needs water. we found that one out. I'll need to do some tub cutting to get the 6 oz tank inside.

I'll need to do some tub cutting to get the 6 oz tank inside. Reading about carb mods, it sounds like cutting the spray bar at 90 degrees gives better fuel atomization. Yes, Bob's .18 needs full water. Kinda funny how some need water, some don't.... My air cooled head should work o.k. I didn't want to run water lines; .12 riggers are so small. I hope to bench run the .12 motor in Saturday night using a heat gun to warm the head before starting. There is allot of pinch, which seems to be the norm for these small engines. Do you have the flex 6oz. slant tank? Mine fit in fine, just need to squeeze the tank. Friction should keep this tank in, but it does stick up 1/4". No big deal since I'm not running a cowl. I like to go in the water early, so 6oz was needed. |

RE: Central NEW YORK boaters
We will have a .45 rigger for testing. I ordered a headbutton on the .45 CMB ,The glowplug thread is NOT right. I can swap out my spare for parts. Do they sell another kind of plug bigger thread???? It's a turbo head, from Stu I'll call him tomorrow. Got me scratching my head on this one. I went to tighten the coupler and added my piston-stop. No good. way off.

c.k.y. , Stu Barr is the CMB dealer over here. I ordered a .45 CMB headbutton and the darn thing has the wrong glow plug treads It was to be a turbo head ,looks like any normal button. Who's that with you ?
I've never been to a world championship event. Must be a big race ,guys coming from all over the world . Thanks for reply Neil |

RE: Central NEW YORK boaters
I always like seeing older hulls from Europe and Asia. The monos alway look like thay are designed to run in rough water...and look like they could 'roll over' and keep on going. Sort of like the current 'Eco' hulls raced in Europe currently. The motor mount in c.k.y.'s pic is similar to a the Solinger mounts we use on our small riggers. Simple and effective. Everything doesn't have to be anodized and cost $65 to work. Roger

RE: Central NEW YORK boaters
Your water tight linkage is a good price as well.Craig I kinda did the same on the .45 linkage. A piece of water line to seal .I'm adding the pipe mount and still need to add the water line. ALSO using that 3 rd channel. I better read up. Bill I have the same 3rd channel needle you have. Which line goes to the carb top or bottom? I think top but need to double CK

RE: Central NEW YORK boaters
Looks like another freeze last night. 34 right now but sunny. We will learn on the fly. Ill bring my flow meter. I may try to start the engine today. And get a reading on the flow meter. Craig my starter parts are here and the box is sealed. I did do some wiring That 2 nd black wire has got me stumped.
