RE: My first boat pics
ok ever needed to tune your motor well i found this article carb 101 & have to say it works great it was in a airplane forum i ran across so ill pass it along it helped me alot "Here's the way that *I* set mixture on non-airbleed carbed engines (90% of the engines out there fit this category, but the theory is similar for air-bleed carbs). First of all, understand that the high speed needle has its main effect from 3/4 to full throttle, and the low speed needle controls everything from idle up to 3/4 throttle. It thus makes sense to me to spend the biggest majority of my tuning time adjusting the needle that controls the largest portion of engine running, right? Also, remember that there is a proper air to fuel ratio (mixture) that allows the engine to run properly. Too much fuel is rich, and too little fuel is lean. We "richen" the mixture by adding more fuel (turning the needle out, or counter-clockwise), and we "lean the mixture out" by decreasing the fuel (turning the needle valve in, or clockwise). I start the engine give it full throttle, and lean it to it's highest rpm (peak), then richen it by maybe a quarter turn. Then with the glow plug igniter still attached, I slowly close the throttle to an idle rpm. At the lowest rpm that the engine will still reliably run, I then remove the glow igniter. If the engine dies immediately, I know it's too rich, and I then lean out the LOW SPEED NEEDLE by 1/8th of a turn (don't touch the high speed needle). Start the engine again, (and this is important) give FULL throttle briefly to clear out excess fuel, then slowly close the throttle again. Remove the glow igniter, and this time it may run a little longer before it dies, so lean the low speed another 1/8th turn. Re-fire the engine, give a burst of full throttle to clear it out, and slowly close the throttle again. remove the glow igniter and now notice that the rpm DROPPED a bit when you removed the glow igniter, but the engine kept running. We're getting there. It's still too rich, and you'll prove that by opening up the throttle and hearing the engine "blubber" then die. That's because excess fuel has collected in the crankcase during the rich idle, and when you opened up the throttle, the excess was pulled into the cylinder, making it WAY too rich. Supposed you were on a landing approach, and decided to go around, you throttle up but the engine "blubbers" and then dies (another thing we haven't seen, right?). Yep, the LOW SPEED needle was still too rich, allowing excess fuel to collect in the crankcase, just WAITING on you to try to go around so it could "LOAD UP", blubber, and die! Keep leaning the low speed needle down until it idles well, but now, when you open up the throttle, it HESITATES instead of BLUBBERS. When this happens, you've lean it down too far, so richen it up 1/16th of a turn and try again. You know you've got the LOW SPEED needle right when you can fire it up, remove the the glow igniter, and the rpm doesn't change AT ALL, and you can open the throttle up, and it doesn't blubber or hesitate, it just runs! The final thing you do is re-adjust the HIGH SPEED NEEDLE, leaning it to it's highest rpm (peak) and then richening it up maybe 1/8th turn to give it a slightly rich mixture. We also know that the fuel mixture will change in flight when you point the nose up (harder for fuel to travel uphill) and also as the fuel level in the tank changes. In both cases, a leaner mixture results, so we actually need to set the mixture a bit further on the rich side to account for this. While the engine is running at full throttle, CAREFULLY pick the model up and raise the nose to at least a 45 degree angle while listening to the engine. If the engine sags a bit, then you'll need to richen up the high speed needle 1/16th turn. Try it again, and when you can point the nose up and the engine doesn't sag, but maybe shows a slight GAIN in rpm, you know you've got it right. Now the engine will be happy, and chances are will reward you with reliable running. If you've got one of the few engines with an air bleed adjustment for low speed adjustment, the theory is the same, just refer to your manual to see how to richen and lean the low speed mixture.

Cograts on the Docs getting all of the cancer. My prayers are with you that it does not return. Thanks, I did not realize just how much I was missing the boats until I took the time to start each one of them a just sit back and listen the engines just beg for some water fun.

Finally Time for PLAY
Hey Guys, its been a super long time, but work has given me enough of a break to have time to crank all of my boats. Looking forward to this weekend, we are gonna take all the boats out for some long over due running. Its also looking like this year we will be able to have the Winds of the Swamp airboat race. We will try to have the race set up for mid to end of Oct. This is the best time of year for racing airboats, winds are normally calm and the temps are normally very comfortable. Race classes will be Oval track and drag racing. Missed all you guys, I'm hoping for enough time off to get things back on track.

RE: help with build for outrigger
best to stay away from building a outrigger as a first build, unless you are willing to build test and toss in the burn can. With any outrigger hull water prop or air prop they are either right or wrong. But when they are right they are down right fast, but to get one right is a lot of building and rebuilding.

go with the 14 x 6 2-blade prop. I would move the engine forward about a 1-1/2" with a little more support on the engine stand.

RE: Am I screwed??
The crank is fine, that is only aluminum from the spinner, which can be removed. Best bet would be get a new spinner nut, clean the threads on the crank, some times the point of a pick or knife can free the aluminum. Be careful it may take some force. Best to use a die/tap. Are you useing the prop washer that came with the engine? if so you may still be in really good shape, its not looking like the threads are bad very deep. Use lock tight. Do not use the washer that came with the engine, the spinner nut is made to apply force on the prop where it is needed.

RE: FLORIDA RC AIRBOATERS
[quote]ORIGINAL: Selph-Inflicted I have access to a 5 acre pond on county property here in Okeechobee County that there is no need to purchase a membership to run at. Nor do we need insurance to run there. I honestly don't see many spending $50-75 to run a few times out of the year when there are ways to do it freely. Like I said, I have a manicured pond that we can run at free of cost. No weeds, the grass is mowed and maintained. My county is centrally located and could draw boaters from the north and south. [/quote] Chris are you willing to host a organized rc airboat race at this location? Or do you have more in mind of hanging out running airboats with a race here and there?

RE: FLORIDA RC AIRBOATERS
Hosting a race is a lot of work and takes more than one person to run a race. Many things have to fall into place even the small things for a race to be sucessful, takes weeks to get it all lined up. But let me tell you and I'm sure that every one that has been on the drivers stand will tell you the same thing, just as the clock starts so does the heart racing, knees knocking, squezzing of the radio so thight its about to bust in your hand, even your eye sight has to take a moment to focus, the rush is like having a 12 point buck walk under your stand, and then the race starts. Then the knees get really weak and the grip gets a little tighter. So all of the work that goes into hosting a race, is it worth it? I've been doing it for some years now and all I have to say is hell yes its worth it. Watch the vid and you will see the excitement even the camera person had a hard time videoing from getting cought up in the race.

There was never any question for you to change any decision that you have made or any that was given to you. Lester simply has the knowledge of knowing what it will take to have a event at the mass majority of different places. Also as Lester stated "I know this type of racing in not for ever one but for the ones that like racing we will have a good time" It is very simple, want to have events at different places get insurance.

RE: FLORIDA RC AIRBOATERS
I'm with you Lester, it is almost impossible to have a organized race event anywhere with out some type of insurance. I'm also a member of NAMBA and between paying for their membership and our local club I'm spending about $100.00 a year. $50.00-$75.00 is fair and as members grow I'm sure the price would be less. Even if I would only race 1 time a year this would be worth it. It is very easy for a handful of guys to go out and run just about anywhere, but the second you try to host a organized race event the tables turn. You are hard pressed to find water without some type of coverage. Every year for the winds of the swamp airboat race, I'm stressing over the fact that it is a good chance that we will loose the water we have and then its starts all over again looking for a place to race. As for the cost, do a little adding. Gas RC Airboat, you are looking at a cost of no less than $750.00+ and that is only if you find all of your own parts at discounted prices and build the boat yourself. Fuel to get to a race event, my last race was just over one state, fuel cost $210.00 round trip, hotel 2 nights $150.00 eating out 3 days $130.00 fuel, batteries and other odds and ends for boats $50.00. All adds up to $1290.00 so if you are going to get out and race whats is another 50 dollars?

RE: 21cc Cajun Gator Style Build Help NEEDED!!
with gas engines you must keep in mind the weight of the engine. 18x36 would be the smallest I would go. 2-bladed 13" prop will allow the engine to turn up better, but as in all builds you will need to try different props. Since airboats are under load at most all times the diameter of the prop is more important than the pitch. Again there is another but...too big of a diameter no mater how little pitch the engine will not spin the prop well. with all tht said you will only see a few hundred rpm difference between the 2 and 3 blade props. Too small of a prop will let the engine turn many rpm's but will not have the footing of airflow to give the push needed to move the boat well. Tip keep a eye out for a cy 23cc engine, many car guys buy a car with the 23cc then up grade, many sell the smaller engine at a good price.

RE: 21cc Cajun Gator Style Build Help NEEDED!!
the 13x8 will be ok but s stated a 2 blade 13" would free the engine better. If you have not built the boat yet change the 33" to 38"
