Project 41" Sprintcat!

[bustitup]

Of course. They will fit...Eric has two in the 41 falcon cat and its the same exact bottom hull

holy shi***!!!!! Uh yeah, thats gonna fly! Hope they fit! They are HUGE!!

OHH, I thought he had Scorps, Bustit. Randy Naylor has had luck with the Monster 200 running the Lil'screamers.

OK, so I said WTF and ordered TWIN Little Screamers, TWIN Monster 200's and 6 - 6-cell lipo packs (12s/3p).

This mutha is gunna haul. No more power worries.

Like your thinking

always enjoy your threads...

That combination was recommended to me more than once... So I figured... Why the hell not. If I'm going to build this beast, why not make it a real beast. 6- 6s packs should power the pair nicely.

Jeff's 078 wire drives should put the power to the props nicely too.

I'll have to do some figuring on the prop size though... This hull size and motor combo are all new to me. 650Kv and 12s = 28k RPM, so perhaps a 55mm prop is a good starting point.

Any way you look at it, beefing up the electronics should make this a fun project for sure!!!

Thanks. I know, I'm a little nutz.

Oops your right rummy...I misread his thread

Fightercat Roger what I posted.....thought. u were getting scorps
I have no experience with littlescreamers but they r bigger than the 4035 scorps

What does that mean?

Are you saying you don't know if they will fit? I don't know either. I'm about to break out the hull and find out myself. Kinda bought them on a whim.

Got a little power hungry and tossed some money at it. I would have picked up the Swordfish HV's, but wasn't a back order option or ETA available. Hell, they might come in before HK the way they have been shipping orders lately. In which case, I will order them anyway.

BTW- I don't know anything about the scorpion motors.

I need two motor mounts though! Any suggestions?

have you not read this thread?

when I read what you are using in your build I misread and thought you where using the scorpion 4035 800kv motorsbut I now see you are using the littlescreamers 650kv motors........

read our build of the 41" falcon cat and realize that the bottom of the falcon cat is a "splash" or copy of your 41" hull

as far as where to get scorpion motors check with steve first ..if he cant get them for you I will show you were we got ours....there are alot more people using scorpions than little screamers

Wish the Falcon had a different lid

This hull was part of a trade deal of a whole bunch of stuff and I'm kinda not liking the size of it. I didn't expect it to be as big as it is. I'm sure it will be great when it's done, but doesn't fit in the trunk of the car (convertable) and takes up quite a bit of bench space, so isn't as practical as I would like.

I just measured and there's just over 60mm of space to get into the sponsons in the hull. It will be tight for sure, but doable. Might flex the hull a bit to squeeze them in.

I still don't know what I'm going to do for a color scheme. Blue and white for sure. Maybe two tone, but not sure how and where the colors are going to go.

I did read the Falcon cat thread, but didn't know it was the same hull till you mentioned it. I already ordered the screamers from Steve, so probably not the time to talk about which motor, more like how to get the most out of these.

I annoy Steve enough with combining and changing my orders after they are placed. =)

Unless there's a big problem with running a pair of little screamers on 12s, then that's what the build is going to be.

Looks like I'll be making my own motor mounts. I do have some nice pieces of 4" aluminum structural angle.

X455 would be a good place to start on props. You MAY want some 1/4" cables though. As Jeff if he thinks his wires will handle your setup though. If the fit, It WILL work. I'm sure you can make them fit though.

Sounds perfect. I haven't finalized the drives, just the rudder, so may upgrade from what I was planning on using with the CC/Neu setup. The little screamers are just a bit more powerful I presume.

So I guess we'll see what Jeff has to recommend as this is the biggest setup I've done yet.

I've got Randy at BBY working on motor mounts. =)

Dear x...

I do appreciate your responses, however one might consider reading the complete thread as to compose more informed and up to date statements.

As a quick refresher; The parts in hand are: Twin T180a ESC's, 2200Kv CC/Neu's, 4mm drive struts, 16cm rudder, 190 oz/in steering servo (for push/pull) and a 41" sprintcat hull.

The only concern is the size of the hull and Rum's Sprintcat is a .40 which is about 7 inches shorter, but much smaller over all. I didn't check on hull sizing when I went to follow his awesome setup. There was a twin prop 55" Arrow Shark vid floating around that is re-assuring as it has the same motor CC/Neu setup and looked good.

The Turnigy 180a ESC's I have get hot in the smaller setups, so pulled out a "Plan B" for additional ESC cooling if needed. The speed goal for this project is quite conservative at 45mph and should do that well on 4s.

Right now, I'm just curious about the color scheme. White base, Blue on Blue accents with silver or black pinstriping. Possibly some yellow highlights.

Maybe I'll break out the hull later and get some more photos to bring into photo shop.

So you WERE considering other motors, HMM.
