RE: Quickdraw MOTOR??
Looking at all the rust that motor has some serious hours on it. Or it has never seen some WD 40 sprayed onto it.

RE: OUTBOARD DRIVE home built
If you spray the foam with a sanding sealer and then PVA paint it stops the resin from eating it.

RE: Canard style Airboat
That sounds a bit narrow. If you consider a 3.5 outboard leg's fin tapers from 35 to 20mm over 40mm length and you have the prop thrust still pushin. When I make rudders for from nitro to gas the minimum is 25mm at the bottom tapering to 40mm at the top. Just my 2 cents. Have any pictures of a side profile view of the boat? Cobus

RE: Canard style Airboat
OK you are off the hook[:D]. The length of the rudder will only give you straight line stability. How wide is the rudder? Cobus

RE: Canard style Airboat
What rudder servo you using? It looked like at low speed she wants to turn but as soon as you put to much load on the servo she battles. What battery you using. Sometimes going to 6volt battery can help. Your canard and a tunnel boat has the same tendency. In our 3.5cc F1 tunnel boat we use a 13kg steering servo and sometimes still have to come off the throttle to turn sharp corners. Cobus And as a side note are you nuts riding your boat while you can hear the thunder in the air. You are standing with one of the best lightning rods in the world in your hand. I woudl be s)*tt(*g myself.

RE: GAS OUTBOARD guys this is our new home
At least about 40mm or 1& 1/2 inch. The 805 alone wont work. Their is enough space in the radio box. Why not mount 2 behind each other and link them? http://www.servocity.com/html/hs-7950tg_servo.html This is the strongest one I've seen. But at $119 it is too expensive and it is digital so a drop of water and you chuck it. Like the fact that it can run on 7.4V so you can use lipo battery without having to put in a regulator to make it 6V. http://www.servocity.com/html/spg645a_standard_rotation.html Better off buying one of these and it is cheaper than a the one above. Monster power and not that slow even if it is 4 to 1 ratio. http://www.horizonhobby.com/Products/Default.aspx?ProdID=HAN3619 The easiest option if you have another 805 servo and can fit it in. Cobus

RE: GAS OUTBOARD guys this is our new home
Special K is that 4x40 rod you glued inside the carbon rod? If so I would use some K&S tubing that slides tight-ish over the carbon to stop it from splitting open when you do possibly knock something. We mostly now glue the fitting over the carbon. Makes it last longer. Cobus And I hope the one 805 servo is going to be enough Motor Type: 3 Pole Bearing Type: Dual Ball Bearing Speed: 0.19 / 0.14 sec @ 60 deg. English Metric Torque: 274.96 / 343.01 oz.in (4.8v/6v) 19.8 / 24.7 kg.cm Size: 2.59" x 1.18" x 2.26" 66.00 x 30.00 x 57.60mm Weight: 5.36oz 152.00g As you can see at 6V at 1 cm from the center you pushing 24.7kg. The way you have your control arms it looks like you going in on the end of the servo horn which I could be wrong is about 2 cm from the center which would only give you 12.35kg of force. As well as making the movement very fast an you are going to have to bring the EPA down more than what is advisable.

RE: Back to work on the crackerbox
Having the 2 lines is all right, but you still have to have a vent line or the fuel tank will hold back the fuel as the carb pump pumps. Best is to run a line and coil it at least 4 to 6 times around your fingers. That way when the boat flips the water will take a wile to get into the tank. When you are back on land make sure you pump fuel through your carb supply line to push out any water in the vent line, otherwise the carb will suck that water in the vent line into the tank and fowl your fuel. That is why the IV bag is used because it can collapse as the carb sucks fuel. Cobus

Don't worry Dom it's not a link thats iomportant to you. Just something I showed Latiff. And Latiff, that was more like 90kph and a small 7016 prop. we had nothing bigger to use cause the rest of the running gear had left for Durban. Cobus

RE: fiber glass mix ratio ?
As Dicko said. Epoxy don't like cold. I warm my epoxy on a heater to make sure it is above 24 deg C. The room can be cold just make sure the epoxy is warm as it wont react. Warming the hull slightly is also acceptable. Had these issues when I started with epoxy and the techies just said make it warm. Good luck Cobus
