I do have the zip 440 ,the problem lies in the start. she likes to die on take offs. I had a 3 blade before, she never bite very good . I wanted to go small on the prop. Then work my way up. I had a X 438 in the video. But I have the AB parabolic pipe on now, lets see what I come up with, just looking for a clean safe run. I better stay with the X 438 2 blade

She must not be broke in yet, or your low speed needle needs some attention.

No slow speed needle Amax . Just the one remote needle , Speedmaster race carb or the .21 ZOOM carb same remote needle .Yes she is still being broke in. My pit man is MIA for now. Looking for a Aeromarine box in the mail. I need a strut foe the cat. The radio box is sealed in .I cant assess the transom , looking for the same strut bolt pattern. I f not drill and fill holes with a wood dowel , then drill a brass tread insert. I am used to the needle on the carb, not inline

I am down to 5 parts left to put on. I have less than a week to finish , I don't like deadlines ,when I build. I use this metal reamer to remove wood where my water seal go. The inside lip of the rubber seal needs to seat nicely. All the holes are drilled & ready to put down my top skin. Paint & seal next. notice the empty holes on the servo mount, you need to use a mini servo. A 3003 servo is to high to put in. OK The top is down. clean the radio box top lid, no globs of epoxy. You need that clean pic #3

No running today high-winds & cool . I need to get to the marina & turn on the bilge pump. We got hit hard, heavy rain's I had plans to bring a rc boat today A real boat. 200 hp Now that's a retriever boat. The Ice came down from my roof over the winter & smashed the windshield. I haven't see her since the repair. My 2 sons have it out most of the time. I just pay, for repairs. LOL It's a 20 min ride to Oneida Lake. I had A big crowd wanting to see the RC boat fly , no running today. I am READY batteries are charged. I want to run in bigger waters to help me get a handle on the speed. My driving is skills are very rusty. The more I run the better I feel.

We are Down , a clean cut, She turns sharp & fast. My trim is down to 20% We also noticed fuel squirting out the head button / case. the head shims are floating in the .21
Miss Jada ,well she's in the closet. I don't want to look at her. the fuel has too far to travel. my fuel tank was a flop. 2 round fuel tanks lets see. We still had a ball troubles or not. I have great some advice in the other boaters. I don't feel like a newbe ,just a lot of good friends. The MM18 was just OK the box was sealed with liquid nail , bad choice. what a gooie mess . Clean with acetone seal with GOOP or 100% silicone. Do you see the screws inside the box. Ya screws , my linkage went on the rudder in one heat. Died in another heat. my servo throw did not open my carb fully Got ran over dead on turn 2 you can see the prop cuts on the topside, near the M With some more work I am on my way See ran semi good. can do better.

One last thing, the .21 Zippkit launch. My .21 HAD a problem with the launch. To run the larger props that you need ( the launch ) has to be right. Joe Petro gave everyone a lesson in proper Zippkkit .21 launch. I wish I took a video. You need to get your boots on & launch Hard & parallel to the water. HARD did I mention SWIFT I think swift is a better term. Wing it like a Frisbee. don't be shy. We also found fuel coming out the case /head-button, a file & wet & dry sandpaper on a flat surface . There is a small lip. I sent a pm to Glenn I am doing the right way. Keep all fillings away from the inside. Here is my reworked head.I had a ear plug in the center. I washed out all metal.with auto carb cleaner.

tnltyme , The engine & hull did not get tested. I was told she will never run very good. I have seen her run. Kinds close on the sponsons. if anything . The guy has 2 V fiberglass . NEVER BUILT A THING. Been sitting now the engine 11 1/2 " to fat of my pipe. I read 2 3/4 on the needle. I my just prove everyone wrong .Yet or just burn her like a Viking ship. NOT
I been kinda bitten with the easiness of the gas hulls. The .67 -80 nitro are a Dinosaur been taken over by gas. The cost to run them got too high, $ nitro $ glow plugs

My Nova Rossi .21 rigger was clocked at 53. If I had my OPS 3280 on I know 15-20mph more. I ran a Andy Brown Parabolic pipe length was 9 3/4 " I will be cutting a 3/4 " off and go back & test. I have a K pipe to shorten also . She ran better after I pulled the needle. To CK there it was FUZZ on the end of the needle. . the water was FLAT We had a 12'boat to retrieve , my fishing rod would never of made it today

Hey guys I've ben a tunnel guy and going to get a .21 zip kit but wondering what you all think of a old Os Max to start out on a zip kit. Now off the bat not looking for 100mph but would like to get the handeling charecteristics down. Will this little engine work out to start with? Will I have to do anything to it to make it work? Thanks guys for your help, Kevin.

kroggs , that's the great thing about this hobby, your OS is still a great fit. You'll have some fast laps. The little .12 Zippkit rigger are being fitted with .12 -.18 buggy engines. no water lines. minus all the fins. weight is key lite is always best. The 40 some page's of pics and easy to follow instructions. Both are very fast. I'm still testing new props. I ran a 1450 modified prop. reduced .it was getting betterafter every modification. The Start had gotten very easy now. No fuel out the head-button. NO heavy tosses. The engine itself is not fussy any more. Starts right up- idle is right on. pipe is getting right. I feel better now driving.

I have a quiet tone pipe for it but not sure it will work so might have to try something else. But then again this is a just for fun thing and will see were that gets me!!!!

kroggs , Joe has a new line of props that come,balanced and modified. At A VERY LOW PRICE. Just cut and cupped for the .21 . His header is very wide. to fit the hull. The new strut I am putting on the MM18 cat. Still to come .I have some video but can't down load my little cable to connect is miss placed.

Sorry kroggs, go to zippkits,com
That's Joes Site
He has more than the site shows so ask His new line of props are a great deal, price wise ,all the work is done, balanced & sharped. I am not sure about the .12 size props We never talked about the .12 rigger . You can have a Gas hull with a engine for around $600.00 all the hardware ,minus your radio

What would you think for speeds a guy could do with a old OS max be? What would the cheapest little engine be that a guy could throw in a outrigger and hit some good sppeds? Thanks Kevin.

The nice thing about building your own boat is you can do any thing you want, nothing is set in stone. Your OS motor should work fine with the right setup. If you want something with potential get a 5 port Nova Rossi from Glenn Quarles and a OPS 3280 pipe.
