    Krylon color maxx spray paints !

    Robert is right. I've been messing around with the rattle can and Createx water color paints covered up with an automotive clear coat. The Createx is great if you have an airbrush or gun but they seem to be brittle and pull up with tape even after clear coating. The Rustoleum rattle can paint...

    Rudder stand off length and taper?

    I have a straight rudder blade on it now. It has been cut down to around 4 1/2".

    Rudder stand off length and taper?

    These are the props that I have. Octura 470, V967/3 ABC 2716, 2719-19-38 Zip 6719/3, 7016/3 Prather 270, 275 So far with the 30cc plus Gizmo engine my boats really like the ABC 2716, 2719-19-38, and Prather 275, props. The others are a bit much for the engine and I'm thinking of doing a Barr...

    Rudder stand off length and taper?

    So I've been searching around and was wondering how you decide on the rudder standoff length or if you want a tapered or straight rudder. I'm guessing that a straight rudder with more of a standoff extension would be more positive steering but is there more to it than that? On my 60" MTI cat I...

    Futaba T-FHSS receiver differences ?

    Thanks guys. after a bunch of research and your knowledge I'm a lot more informed of what receivers I should be looking at. I didn't think about the gyro and fast servo response for that purpose. That makes sense for those applications but I'm pretty sure I don't need that. I'll stick with...

    Futaba T-FHSS receiver differences ?

    Futaba T-FHSS receiver differences ? I'm trying to make sure I understand the T-FHSS receiver differences before I buy a few of them. Can someone please tell me if I have this correct, or if not, can you elaborate? I am using these in gas and electric boats. I have a couple R324SBS and a couple...

    Walbro 257 Carb Fuel Inlet Position

    Or you could use something like a mighty vac for bleeding brakes. Mine does both vacuum and pressure.

    Walbro 257 Carb Fuel Inlet Position

    I just did all three of my engines. They all were pretty tight and I thought they would crack but I got them to twist about a quarter turn each without cracking. They all did leak afterwards however. I just put a small bead of JB Weld around them and all is good now.

    Need a retrieval boat

    Chris that is almost exactly what I'm making out of PVC right now too. I also thought about a pivoting motor mount to simplify things but was wondering about the prop clearances when at full lock. Do you find your set up works okay? Anything you would change with it? Would like to see what you...

    Need a retrieval boat

    I have a 10' fishing kayak that I use to retrieve my boats. My 60" gas cat is a handful to try and get into the kayak with me so I use a suction GPS mount and some small rope to tow it back to shore. Just slap the suction cup on the bow of the boat and tow it in. I'm working on a PVC and pool...

    Blazer Marine Slingshot Build!

    Thanks Mario, I'm collecting quite the number of props for the gas boats but I don't think I have that prop yet. I can't seem to find it anywhere. What is the dia, pitch, and rake? Where do you get them from? I''m building the Envy gas rigger right now and putting a Gizmo 30+ in it.

    Blazer Marine Slingshot Build!

    Looking great Mario! What is your pipe length? In the pictures it looks like its more than 13.5 inches from the face of the exhaust port to the widest part of the pipe. Just wondering if you have experimented with it at different lengths and what you came up with on your engine. I also...

    Electric power for 60" cat?

    I was wondering what a good option for going to electric would be for a single motor replacement of a 30cc gas engine in a 60" Cat hull? I've been looking at the Leopard and SSS 5690 to 56110 size motors in the 700 KV range for 12s. For esc's, Swordfish, Flier, Hobbywing, ZTW, in the 200 to 300a...
