Yes still have the tank. Aquacraft (Hobbico) already sent me a new tank. was thinking of sending it back to the to run some tests on it or something. Well put the new tank in, went to the lake today with the big boat and brought the two little boats too... SV-27 and Miss Vegas. With the new tank the Vegas was finally running good, and so far tank seems ok. Got it tuned in and ripping up the water. installed the grim racer 36*55 prop on and was having some real fun. we were set up in a nice quiet cove where the water was pretty smooth, but had to keep on my toes cause in the cove there are three sides to worry about. Had a bee start buzzing around my face and swatted at it probbably 3 times. next thing I know it lands on my face, and while trying to get it off my boat runs right up on shore and skipps over the rocks. Didn't hurt the fiberglass too bad supprizingly. Broke the rudder right off. Banged up the new prop pretty good and pulled the flex shaft out of the collet. prop and flex shaft was hanging half out of the boat. Funny the little boats are just like the big boat, I'm constantly working on them.

I could really use the piece that screws into the top where the fuel pick up line is. If you don't need it you would be helping me out huge. I have 2 tanks ordered but they are on backorder. My tank is fine except for that piece...the top of it broke off inside the line.

Wow. when i called hobbico about my problem last week, I had the new tank in 4 days. Ok, I know what you are talking about now, I thought that piece was plastic welded to the lid. I'de love to send it to you but I'm just starting to acuire spare parts for my boats, and the way I'm going, i think I will probably be needing it... Sorry.

I totally understand you are probably better off keeping it. Sorry to hear about your boat and hope you get her back and running again soon.

just ordered new breakaway rudder and extra sheer bolts. will see how long it takes to recieve order, but it looks like this rudder will be better than stock one. Also glad I didn't rip out the transom. Might have to order a new speed prop. have two more stock ones for now.

I haven't been on the site in a while do to a blown engine. I am getting the cvr-m any day now and was wondering what kind of fuel people are using with this engine. Also do you break it in the same way as the stock motor. 6 tanks of fuel i think it was. Also can you pull the head shim off like with the stock one. Any help with this would be greatly appreciated.

Yes, about 6 tanks does it. Start about three and a half turns out on the HSN. I run 40% in mine. I still have the shims in mine. I saw one guy that took the shims out of a CVRM and you could feel the piston catch toward the top of its travel...put shims back in and could not feel it. I think the piston was barely making contact with the button with the shims out. I am sure different engines are all a little different...but something to look for...

as far as breaking in a cvr-m, as I have done with both of mine, I hook up a flow of water through the head, disconnect the shaft and run it on the bench,so to say, and run about 1/4th a gallon through it running rich and at time's leaning it out to get it hot, then back to rich to cool it off, it take's about 1 hour, but she will run when done, also DO NOT remove the head shimm's, and I have had good luck with O'Donnel boat 50% fuel, have about 3+ gallon's in my one cvr-m engine, and she still has lot's of compression and life!!

Ran the MV last night,and hit something in the lake!

It took big chunks out of the rudder,and cracked the transom across the top seam. I've cut the leading edge of the rudder back,and repaired the transom. I also replaced the bottom bolt on the rudder with a nylon one,hoping this will shear off instead of wrecking the back of the boat. The boat is really flying (at last) and will blow over when the fuel tank is almost empty,I added a ounce of weight to the "ballast box" in the front of the hull. The square (wheel weights) are held in with velcro,so you can add,or remove them. The boat has cracked in many places,and is bondoed up,but I plan on tearing it down this winter,and sanding ,and filling the hull,then a new paint job for next spring. Our lake was a "clean lake" before the big flood waters covered everything,this year. Now I think we have a bunch of rough fish carp,gar,ect. in there,and they cruise around just below the surface in the evenings. What ever it was,it took a real hard shot when the rudder hit it.Are you guy's using fuel proof paint when repainting the hulls? Ron

ok guys.. i have been reading for a while and this is my first post in this thread, i have been flying heli's for quite some time now and decided to get a nitro boat, i picked the miss vegas, here are my mods, i ported the exhaust header, shortened the tuned pipe 1/2", removed the shim from the head of the .18, sharpened the leading edge of my rudder, removed the rear fin.. here is my question, i have a thunder tiger pro .21 sitting on my bench.. it fits in the vegas perfectly!! i just need to find a couper for the flexshaft!! the threads on the crank are larger than the stock .18.. anyone have a clue?? is this a good motor to put in the vegas?? i went to twisted liquids site and they are no longer selling parts for the vegas.. i also need to find a couple auto bailers.. i will have one in each corner of the boat.. i am running 30% nitro fuel with 18% oil. i also mounted the motor on rubber to stop bad vibrations, and re-did the fuel pickup in the tank.. anything i am missing?? i am thinking about trimming out the rear of the canopy (the turbine engine) but before i do i am wondering if it will be impossible to idle along in the water with it cut out like that?? i do stop from time to time to take a drink or do something.. me and a buddy go out on a private 60 acre lake in my little john boat and let them rip!!

Cut the rear out of the turbine (dummy) exhaust,also cut the two lower vents below the drivers window in the cockpit. Auto bailers (auto sinkers) will work,but a simple method is to drill two holes in the transom corners to let the water out. Add flotation to the rear section of the hull. Once you get a good prop on the boat,and setup right,you won't be able to idle around. The boat will be very hard to get up on plane (step) after slowing down. Also treat the wood frame work with resin,poly urthane,ect. as it see's allot of water inside the boat (most Hydro's do). When you get the boat setup for all-out speed,you will have to give it a fling,and get on the throttle,when you launch it. Then never get off plane until you are right at the waters edge,to land the boat. Ron

Got my Vegas a couple of weeks ago! I was impressed the minute I pulled it out of the box, put fuel in it, and it fired on the first pull! I have run 10 tanks of fuel through it and it gets a little quicker every tank. I have had only one problem with mine, I burnt the pipe coupler out on the tenth tank. I replaced it with a "Pro Boat" coupler that seems to be a little thicker. I will let you know if it gives me any trouble.

I haven't done any modifications to the boat and I enjoy running it every time I put it in the water! I don't race competitively, so I don't really have anything to compare it with except my nephew's boat. I can follow him through his wake and never lose ground to him, though. So the boats are pretty evenly matched!

This is my first boat and I am having a ball with it. I just wish there was more interest in my area where we could get a race together.
