Going to build a Rico 31

[rearwheelin]

Hello fellas ! Wanted to hear some input on the 31'' Rico that has caught my eye after recieving a few xmas bucks. Really think this hull will handle a castle 1515 better than a titan 29' on 4s' or my other choice was the Titan 33 wich could definatly handle the speed of a 1515 on 4s with no worries. I really am wanting to build a boat someware between 29 n 33'' that will run in the 5o mph range with good high speed stability in the turns. So far in my head I have a Rico 31, Turnigy 180 with water cooled caps , 2 Turnigy nano tech 5000mah 4s packs, x440 3 blade , mono 21 rudder, build my own carbon fiber servo and motor mount and possibly turn fins, Speedmaster extended mono strut.......
Just kicken this boat around in my head and planning for a boat that is not so serious but fun and somewhat on edge...

keep in mind that the rico is a heaver boat than the rest of them. also if you install rails you may have a hard time getting 2 x 5000 4s on the sides they may need to be mounted in the center. i also feel in order to get 50 mph you are going to have to pull a bigger prop than 440-3. i pulgged a 442 into the on-line fe calc and came up with 48 (90 efficiency, 2200kv, 4s). i think a 440 is just to small for this big and heavy of a boat. with a similar set-up mine is over 8 lbs. (almost 9 some guys run them right at 10). 1521 is 5oz heaver than 1515. 5000mah is 84 grams (2.84 oz) more than the 4000's i use, so the difference is minimal. the weight is what makes them drive so good.
i am not saying a 1515 isnt the right motor just saying you might want to start thinking 445 - 645 - 447/3
i will say that i do love the rico. i have run 1515 1y in everything from df26, df29, df sniper 32 and they all can handle it. personally i think the rico 29" would be my choice. i have a df29 right now with the leopard 40-74. i ran it yesterday for the first time and it seems to like that motor. it is proped way down (x442) because i am only trying to get 40 (was actually running 43) mph but it drove nice and i know they can handle 50 good.

Thank you for your input , really is great advice to get me on the right path ! My last mono was a titan 29 , it had the 1515 neu 2200kv with a inline rudder setup and it was standard thickness hull with carbon inlay from front to back and had the speedmaster extended strut . I had it built heavy duty from aeromarine. I ran it with 2 5000mah 40c turnigys with gps and it went allmost 53mph with x440 3blade ! I I really do believe it was only able to achieve those speeds and not blow over was because of the inline rudder wich i believe helped it to ride really level because of direct prop wash at rudder pushing back on the rudder, i think it also added drag possibly taking away speed.In the end that boat didn't turn good enouph for me and it had really bad left turning habits and occationally rocked possibly because the batts wern't in the middle it was way to fast for a titan 29..lol. With this Rico hull now I know it will handle 50+ mph speeds with ease and with an offset rudder will be able to rip around the pond in any direction ! I will try and build as light as possible just so i can run big batteries. I'm still kicking around the 29'' idea also. Leaning towards a bigger prop too if i go 31'' but i feel the amp draw could ruin my day if i go with a 2200kv 1515. 4s will be my batts and turnigy 180 for sure though.

Just orderd a Rico ! Greem with yellow splatter with no strakes or carbon inlay. I will post all my pics and a vid when this little pond terror is done !

I just thought of a trick motor mount ! I dont think one like this has been build before Hang tight ........its going to be a bit before i build.....Momma warned me not to get sucked back in.....................................................

New motor mount design idea !

This will be my motor mount design going into my Rico 31'' . Forgive my lack of artistic tallent. I think this style design will help take alot of stress off the hull and send it to the trasom were it is stronger. .....................

I will be making a inclossure for my esc and fill it with a non conductive heat transfering fluid for a supper heat sink. Idea is to turn a Turnigy 180 into a turnigy 240.............

Excited to see you building a Rico.. I bought Ripfences old Rico 31" he built not long ago... mine has a 1521 1y in her :) Aaron (Ripfence) said the hull easily handled it.... in fact he said the 1717's I had laying around would be fun in it too... I almost tend to agree because once you hold a Rico in your hands you will see what I mean... I own a Titan 29 as well and have had Df33's and Df29's... this rico is much stronger, sturdier and heavier as well... I think the 1515 will have its hands full..... a 1520 would be a nice fit as well.... or a 1518.... the 1515 will get er' done... just gonna be worked a little....

Oh and too bad you aren't close Randy... My Best Friend owns one of the largest Steel Yards in New England... "Captial Steel and Supply" his name is Jay Carr (AKA Dirty Carr, and we don't call him that cause he keeps his Car Dirty..LOL).... I wonder how reasonable it is to ship steel? probably not so... lol... when I need anything I just call him.... he delivers it to me, and I've never paid a dime for it... he writes it off as "lot theft" :) Let me know if he can be of assistance... he'd be glad to help ya out.... take care Randy I'll be watching this build...

Thanks J , will see what happens heer first, then I will try out the hot stuff...lol....................................... ......just got a call from the machine shop....$3500.00 for a min 19' length of 10mm tubing.....what a joke Looks like J needs to hook it up ...............I think I will need to call speacialty metals in WashSt..... ....Need to sell turn fins and motor mounts to yalll now.....so I can get what i want...

Randy, FWIW I run a 31" Rico with a 1515 1Y in it. The motor will take you where you want to go if you don't get stupid with props.
Three District Championships and the IMPBA 1/3rd mile oval record and there is more there. The boat weighs 10#s ready for the rough stuff.
Put a m445 back cut 1mm on it and let the horses run!!
Good luck,
Doug
PS Be careful trying to increase the ESCs capacity with a oil bath.

Let me know exactly the material u need word for word and I'll look into it too... My buddy has a 38ft fountain that owns the steelyard so he's a softy for anything to do with boats:)

I agree, I have a 440 3 blade and some 445 I wont get to crazy with the esc , I mainly am building a sport boat with 5 min run times. Really do appreciate your input ......thanks

Super tough hulls BTW. No reinforcement needed. It surely will not flex torsionally with a normal style motor mount. I have a green with black splatter Rico 31. Running a Neu/Castle 1520 and a cupped x447. It flies! Favorite mono by far.

[rearwheelin]

Nice Rumdog !...... I haven't heard anything bad on them. Only that they are as fast as a DF33 and will out corner them too. I ordered mine plain layup , no carbon or strakes............green with yellow splats.........

[Chuck E Cheese]

i wouldnt waste time and money with the fancy mount either. these hulls are bullet proof and dont flex. 1521 on 447-648
