My Delta force 26 SAW build for P,Q,S

[maddmatt]

002.jpgWell, I'm going to give it a try to build a boat for all 3 SAW classes since there isn't any min. size per class. My goal is to build a boat w/ a extreme power to weight ratio and low cost. In the photo are most of the parts I will use, give or take a couple extras. The hull is a DF 26 which will be powered by a Leo 4082 2200kv and a T180 (just for trials) I will add a neu 1521 2900kv or 1521 3100kv w/ FC ESC and just changes batts per class. All I have to do is make it go straight!!!

I got the DF 26 hull from OSE for $80. My first impression is WOW it is really small and cute. Could be the dingy for my gassers. The quality is very nice and very straight. The glass is a little thin but no big deal. I wish it had a larger ledge on the hull where the hatch sits. I like to use a seal and screw the lid down. I'll make it work. I'll install a couple pieces of wood epoxied in the frt. corners where I can mount the retainer nuts. The rear has a large step so it good to go. Here a couple of pics. 004.jpg006.jpg

The next thing I'll work on is the stinger. I bought the stinger from HK for $10. CHEAP!! There is a reason for this cheaper stinger. First is the cost , second is the mounting plate. It allows me to oblong the holes so it will work for a flood tube. I will need some vertical movement for fine tuning. Also I'm going to run a .150 cable w/ a 3/16" prop shaft so the stock stinger bushing will need to be changed. Thats easy to do. I drilled out the stock ones w/ 1/4" bit and pressed in 3- lead/tef. bushing to support the shaft. Some pics011.jpg

The next thing to do is placement of hardware. Here is a quick setup. I might change it. After premounting all the goodies w/ double sided tape, I found out the transom isn't straight. It angles in toward the top. I'll have to correct it by sanding the rudder base. I bought the rudder from HK for $20. Quality is good but the foot print is small so I'll have back it for support. Here some more pics. 013.jpg016.jpg022.jpg

Why not use a stronger .187 flex? Youll be putting alot of power out. IMO, a .150 wont last.

Making it go straight will be the easy part. Keeping a 26 inch hull mono on the water at 75+ is going to be the hard part.

Don't even think about running a .150 cable with a 1521 unless you don't like your prop.

Good luck!!

[maddmatt]

I agree .150 is small. I'll have to be easy on the trigger. Its for SAW only. It worked well w/ the 4082. Still got all the props. I'm concerned about spinning mass. Probably shouldn't be concerned about that w/ a 1521. LOL

Yeah no kidding..I have 50$ just in my x447/3 b/s prop..Put a .187 flex shaft in it definitely..
For instance..If your sawing and it comes out of the water for a split sec and then enters back in thats a major stress on the flexshaft..Just do it...

[maddmatt]

Regarding keeping the boat from flying away. I have a few tricks that I'll apply and maybe they will work. Will see. If it doesn't work after multi attempts and the boat is still intact. It will be detuned and given to my kid. Its all for fun. To test my speeds I'm going to set buoys(fishing bobbers) proper distance and pass by my custom floating radar gun. My gps won't fit in the boat So thats the best method for recording accurate speeds.

[maddmatt]

Ok I'll go w/ a .187 cable. I can use the .150 in other stuff. I have to place an order w/ OSE soon for a couple of other goodies.

[Chilli]

Good move!! We wouldnt steer you wrong. Well.. some might. LOL You'll be spinning over 40,000 rpm and that puts allot of force on the flex.

BTW- I'm doing a SAW P-Sport Hydro and P-Tunnel (Cat) myself.

[maddmatt]

I see your a main guy out east regardin IMPBA. Do you know of a event close to Wisconsin where SAW speeds can be recorded??

[Chilli]

I'm not a main guy by any standard. LOL

There are some Great Lakes guys here who will hopefully chime in.

All the IMPBA sanctioned trials events are posted on the IMPBA web site in the Roostertails Newletters's Master Race Schedule. The December Roostertail is current and there looks to be a record trials event in Flint MI in the first weekend in May. I also see some races scheduled in WI this year. Check it out.

[maddmatt]

Thanks!! I'll take a look. Flint MI is on the other side of Lake Michigan about 600 miles away unless I take a ferry across the big lake. Too far to play. I'll look into Wis. Events. Are you going to post your builds?? Anyway keep watching my build. It should almost done by tomorrow night. I love these little boats. Quick, easy builds and cheap to do. The cost of one gasser motor = 2 builds (not including batts or radio) Have a good night!!

People are ususally pretty secretive about thier SAW set ups on the net. But if you go to the trials events I find most share thier set ups pretty openly and everyone helps each other out. It's a great time and you learn allot.

Nothing special about my Sport Hydro. It's a Insane FE30. I've used it for P-Spec Sport Hyrdo and record ovals.

I'm working on the cat. I'll post some pics after I get it together.
