41" falcon cat build

[mobychev]

another falcon

Just thought you might like to have a look at my 41 falcon
not as ambitious as yours, mine is a budget build, but goes quite well, still tweaking, it does 90kmh but is running a bit wet and will have to try some more props yet. motors KB45S , Etti controllers, 6S1P to each motor 5600MAH

Looked at your set up, your stated performance sounds pretty good as long as your stuff is running cool , i dont have any expieriance with kb45 motors what kv are they ? I would try moving your batteries forward looks like your cg could be off and maybee that is why it is running wet.
Mine is a budget build too, 4=$32.00 540xl 9 turn's from H.C. I might put some real dynomite in it later but for now my goal is 60 mph on 4s with cool temps .

rearwheelin, moving the batteries forward will cause the boat to run wetter..

Yeah I LOL'ed when I read that too.

Ive seen the Falcon first hand, its a real nice tidy build. Should be able to lay the smack down on some petrol boats once its all tuned Graham!

nice job man...any more pics of the motors mounted and stuffing tubes?

[mobychev]

Hi
The motors are 8 turn which are 1700KV
The batterys are on a sliding platform so as to move CofG easily, i think thats fine, it needs a bit more,angle on the stingers thats all, havent had a lot of time to play with this one .
Will try and get some video soon
thanks
Graham

[crabstick]

its only been wet 5 or so times hasn't it Graham?

Bit more tuning and it should be hitting 60mph no sweat

Let me know if you want to go for a run at BP tomorrow and I will bring my video camera and gas cat for a run..

OO heck .... I dont know what a wet boat is...lol...I thought wet boat was the point on a boat were the wieght is to high and causing unnecessary down force and drag and could be corected by redistributing the wait . Sorry fella's , My boats all need the wait up front or they will blow over.....

OK big update here this boat just got bought by my son in law and I get to help him build it which is great since I had to sell it now I get to help design and help with the build and watch it run,,,,but some big changes Have been made.....my son in law (Eric) is kind of nuts...no other way to put it...everything he does had to run on its limits so I just ordered another 4035 800kv outrunner and two swordfish 240 HV esc's...two speedmaster stingers and going to run twins in this boat....just ordered the 8 6s turnigy's so the boat will run on 12s for each motor


I need some help on what left and right prop to start with...andy brown from cmdi has a matched set of x450/3 I could start with...any suggestions here?...flex shafts are .187 with 3/16" prop shafts l&r naturally

this build will move much faster now
the goal is 100mph

This project is now awesome
Please post any progress with a few pics.
should be Ballistic with a capital B..

[rearwheelin]

Make sure you video the first time out , I think this boat is boing to fly !!!!
The x450's sound good but i would try 447 l n r 2 blades first.Also dont run your prop to deep, bottom of strut no deeper than bottom of sponsons, probably 1/8'' to 1/4'' obove sponson. Also ,do you run thrust washers, I used octura 3/16 3/8 o.d .size(all 4 in the bag), you will also need to counter sink the bushing into the strut ,( if you dont do this you will risk grinding you bushing off into you strut) I like my boats to thrust with the drive dog and strut and not the cable, speed master is the way to go !

That a great first run! Hows was the heat on the KBs? What props were you using?
Lots of potential with this setup especially on 6S
