I got the new Formula RTR boat and have been reading most of the miss bud threads, but there are two things I am not sure about. The Bud guys say to fill the sponsons with something to make it float. But there is no access to the inside of them in the formula. I dont know if its a whole different hull, so will it be fine or should i drill some holes to fill it. Also they say to dill a hole in the engine bay to let water out, the formula comes with a drain plug and I plan to put a auto bailer in so will I drill the hole on that side.Heres a few pics as well.
Thanks for any help
By the way the pic of the engine bay is after a gave it a layer fiberglass and a coat coat of paint

That fiberglass layer might helpyou.[&:] You need to drill a hole in the left back corner right at the radio box meets the motor compartment.[8D] I had to do that but later on it was to late!![:@] I riped out out that wood and went back to the old motor mount like the first gen miss buds.Water water damage was bad to the wood Rusted the motor mounts inserts,cause the mounts insert the spin/stripped out.[:@]Also you should use neverseaze on those mounts inserts=helps the threads not to rust up on you. You cant put foam in that style of hull,that foam info was for the first gen miss bud=strait shaft version,But I can now since I rip that out. I have three of them two flex drive and one strait shaft version. But some might tell to drill a hole and use blow foam,But you will run into troubles!![X(] That blow foam will exspand alot and no way to excape= the foam will crack that hull=deep troubles for you.[X(]

There should not be any raw wood exposed anywhere in the hull, if there is mix , up a batch of 30 min epoxy and thin down with some alcohol and give it a good coat . The thinned epoxy will soak into the wood and make very waterproof.

misshydro

The proublem is the back side of that wood isnt water proof![X(]Water does at times go on that side =wood can still rot out and those motor mount inserts will rust up on you=motor mounts that will not unbolt=you will end up spripping out those inserts=wood replacement.[:@]That why I'd riped out those woodside walls out and went back to the old Miss Bud first gen mounts.[8D]Proboart are going to have proublems with that setup.[X(]

My fiberglass skills are really not that good, so I don't really want to have to pull the boat apart for a wile. But I was thinking, can you drill some small holes in the sides of the engine bay and inject some 30 min epoxy that is thinned to a oily viscosity and try swash it around and cover everything on the inside. I'm not even sure if you can thin it that much.

misshydro

Dont even try that!!![X(] I should know this even the the guys will tell you this.[]I'd got my first Miss Bud and the hull was alittle weak in some spots.[:@]So I'd poored some reson in the hull and swished it around and let the rest of reson poor out of that hull.Gess what??[&:] That stuff made my hull heaver= slow boat that couldnt get up on plane![:@]!Plus you dont want that boat be evern more heaver then it is.[X(]It's heaver then the first gen miss buds.[X(] Now I just came up with this idea tonight!!!! And it will work!!!! I'm going to make a temp of that wooden side motor mount and make it out of 1/16-1/8 alum and have the motor mount nuts welded on the other side of that alum plate.It shouldnt be any heaver then that cheap wood they put inside that boat. When I do this I'll post pics of that mod!!

just coat all the exposed wood with epoxy(thinned a little) or resin that you would use when glasing, and you will be fine, if you want to keep metal stuff from rusting put a little oil on it, like on a screw before you screw it in and then no more worries...after seeing a first gen buds engine mounts I would not want to run them...rails are moch more solid and spread the load out better, yeah they may be harder to seal and maintain but its really the way to go...

misshydro

just poped that wooden side out of my other Miss Bud as you can see thats cheap wooden inserts!![X(] Plus those motor mounts inserts nuts are steel=rust!![:'(] here's pic of the miss bud that I'd just poped that out of.[8D] Also pics of my.21 miss bud I took out the woodern side and went back to the old wooden mounts like first gen miss buds and MV also use that mount system too[8D].

suckerforamoneypit, I think what you are going to find is that there are not a lot of folks that have your hull. The hull was redone from the 2 older version of proboats. The new hull does not have the rear shoes (ride pads) and is lighter (thinner) than the old hulls. I do not own one, so can't give you any advise on what to do with it, but just a word of advice (caution?), a lot of folks are going to give you advice based on the older version of the hull. The advice might, or might not be relavent to the new formula hull...so you are going to need to digest the inputs and see if any of them apply to the new formula hull.

You get to kind of be a guinea pig for others to learn from

That hull is no different then the flex drive Miss Buds!!![8D] I should know!![8D] I have three of them!![8D] One old Miss bud strait shaft and two new Miss Buds flex drive hulls=second gen buds!! The Flex drive Miss Bud hull is more heaver,thicker hull![8D] The only thing is different is they cut off the rear tripples on the formula!!

misshydro, I have seen the first gen in person, and I think although easier to keep, those engine mounts provide less strength then having the side rails...more so in starting, like the force from a pullstart or a starting belt being pulled tight, so Id stick with the siderails, they are in the newer boats for a reason, just like the flaxshaft is in there for a reason...when you rebuilt the old style engine mounts you probablly built them stronger then they where when stock...so anyway, Id kinda like to see a formula run next to a vegas since they have the .18 now...my choice still lies in a vegas as far as a hydro, but proboat is starting to get there stuff together...

misshydro

The wooden rails I'd poped that out of my little brothers Miss Bud flex drive.I'll use alum one in that boat.If that idea works I'll put that into my miss bud flex drive.21. I put the old style wooden motor mounts in it two weeks ago![8D] I'd came up with this idea of using alum plate side peice in place of the wooden one tonight. Plus with it out I can now put foam into my boat and put the mounts back in it after the foam job!!At least if my boat takes on water ??it wont sink like the other Buds,Llumars Elums,Formula boats will do.[8D] heres the plate I'll use.It's alittle thinner then the wood but stronger and should be about the same weight as the wood.I got to get a new piece of alum,dont have enought to make the new side mounts.

Its not going to be very much fun laminating the aluminum to the glass hull with any hope of it holding up for very long.

misshydro

I'll notch the edges out and epoxy it in or use the orginal JB weld on it.it will hold it in but good.

suckerforamoneypit

Well thanks for the help guys. I done just about everything you guys said to my boat and I got to say it seems like a whole different boat in the water. But the best improvement that i could really see was with a new prop and a sanded the bottom. Once I did this it ran a little faster(i think it did, I dont have a gps so i can give real speeds) and it gets up and plane much faster.

suckerforamoneypit

ok now i got to ask, will the adjustable strut setup from the vegas really make that much of a diff. I am new to rc boats so i would think you would need a lot of knowledge in boating to really be able to take advantage of the adjustable strut.

terry kelly

you can get a adjustable strut online made for your boat i have them on all 4 of my proboats and they do make a huge difference in the handling and speed. you can get them from one person only but i am not allowed to tell you who it is , if you want to pm me i can help you out. but i do recomend installing one.

well adjusting my strut on my mono got the prop out of the water more getting it on the pipe, and it went from 24mph to 38mph, just cause it was running out finally, so in tuning being able to move the stut can help alot...I adjusted it up even more and got some more speed but flipped before I could get a reading its at least 40mph on 20% nitro so with 60% it should really scream

misshydro

I'd made my own adjustable strut setup by using miss vegas strut and rudder and flex cable and also made my own strut bracket.[8D] I didnt want to buy one for that place that terry was taking about because,I might not get my parts on time or not at all,to many compaints about them.[] heres my setup only cost me 16 dollars to do it.It's fixed now the pics can enlarged now.

Ok so this is what I am going to get, so if anyone knows if this will be all i need please let me know and if it effective is as you guys said not a bad upgrade for $70

here's another thing you could do?[&:] I'm going to do it.There's two MV threads,I'm going to asked any guys who'd upgraded there vegas to.21 or have any spare parts there not using,would they want to sell them??That's the route I'm taking first before buying part.I going to do the samething on my baby brothers Miss Bud flex drive. Also you need to change the flex drive tube to!! it's not long enough to go it the strut.But for the one that arent skilfull,I have an idea!! You could add on what you needed and solder a slip cupling over the two tubes!

suckerforamoneypit

Well I don't really want to spend the money on a after market strut till next summer. So I used a few washers to lower the the prob 3mm. I also removed the spoiler, I did see a difference in the boat geting up on plane and mabey speed but i have no way to check it. The only thing I am not sure about is how much the prop should be lowered from the stock setting to make a real difference.

misshydro

For some reason if the prop is set more upwards you get faster speeds then lowering your prop downwards. If you read the vegas threads,you can reads and see by adusting your strut upwards you gane faster speeds.[8D]

My Feedback: (20)

raising the prop allows the engine to unload more and get to its peak in the powerband... lowered it will get more bite and on plane faster but it will hurt top end noticably...at least this is the way it is on the several monos I have had or helped work on...

f16man

One thing jumps out at me is those garbage plastic props you gota loose them first thing, your boat will trim out much better with an octura or grim prop and get the power to the water .
