Pyr0D3vil79: Very Nice Boat! Best Regards from Germany !
steg140: thank yo so much for your answers! so if I could find a 28mm motor with a
maximum of 1400kv I may have my problem solved? I guess the stock one was
defective then or it should have not burned..am I right? I saw your first
run when the boat was stock and it seemed everything was allright...
DiehardRCaddicts: Sorry, don't know what you mean by 4mods
DiehardRCaddicts: @VitorHugoz as seen in the video the water did not ruin the motor. You just
have to be sure to check the bearings and keep them lubricated.
Frank Kjøllefjord: Hi Frank what did you do with the motor and parts inside? I own a Dragon
Tamoil F1 that look very similar to your boat, inside my boat it's
impossible to do anything as i think the parts was put inside before the
hull was placed around it. Also the sleeve that is suppose to connect the
motor and propeller shaft drive me nutz... the locking screws will simply
not lock the axels in place (i end up breaking the allan holes in them.
Thus i'm looking to outboard it now
DiehardRCaddicts: We haven't tested the Sprint F3 so can only give suggestions on that one. I
think it is smaller than the Hornet F2 so you may be more limited as to
what you can run. If you are going for 6s keep the motor kv rating around
stratosFZ1: HI Frank first of all thx for all the mods u upload to show how the hull
can be better!U really helped me!I tried to put also a 4 cell lipo in my F1
but when i test run the boat at full throttle the propeller (with the shaft
propeller went out of the outboard leg!!!:(:( So i d like to ask you the
upgrade that you bought from ebay is ready to install??What i mean is the
the outboard unit has already the flex shaft inside and a prop shaft or u
put these parts from the stock outboard lower unit?THX
redrumm101: Im thinking 4mods is a screen name for someone.
Anuar Razak: Frank - have you tested the new Sprint F3 ?The stock motor is a 3000kv on a
3s -.Any suggestion for an upgrade to a 6s
Dismal Dream: Don't spend more with hobbyking than your willing to lose.
traxxasinsane1: hey would a inrunner brushless motor work on one of these thanks!! Brian
startazz: Nice going Frank mate and i hope we get to see that bad boy going with the
6s batteries in there ;-) but it looks to be going fast enough with just 4s
and thanks for sharing man.
catamaranman333: I knew it was only a matter of time before the 6s batteries found their way
into a boat.....
DiehardRCaddicts: Angled down 1 or 2 degrees with the prop center line even with the bottom
ride surface of the boat.
S30Uploads: its a channel, maybe its just that sprinkler in the lake, they must be
kinda common. anyways, check out his channel I bet you'd make good friends
Simon Clements: Hi Frank, I've copied your mods, except I got the large aluminium leg. It
went ok on 3s and is very quick on 6s. However the 5mm shaft has broken on
at the coupling on only the second speed run. I was using a 40mm aluminium
propellor. The sales guy reckons 6s is way to much. What shaft are you
Rick Shane: I want an Asian girlfriend that will come out flying with me!
Frank Kjøllefjord: Ok thanks for replying :) I've been able to sort out my locking screws
problem... finally. What do you suggest to do to extend the drive time on
my boat, is it is now i run a 1.11V 3S 2200mAh which give me 8 - 10 min.
run time. The ESC is water-cooled 50A so i guess i can upgrade some, just
wondering if it will be worth it.
DiehardRCaddicts: Yes, and you just answered all your own questions.
steg140: thanks! I'll try describing you a few more things, maybe you can help. in
both the cases the boat ran with a 3 cell 5000mAh li-po battery and the
cooling was perfectly working (I did the adjustments you did in your first
videos so I could see the water coming out), in the first run with the
stock esc, in the second one with a 30A new one. when the boat runs the
propeller is near the surface, the second motor was a 4800kv. cheers
Natalia Saavedra: nice video and boat. what did the adjustable motor mount do for you? did it
make the boat turn better? My boat tends to hook and spin out. maybe im
turning it too hard in a tight circle.
steg140: haha nice vid, funny
DiehardRCaddicts: This boat comes stock with an outboard setup. There was no motor or drive
hardware mounted inside the hull when I got it. I just upgraded to a better
steg140: thank you very much, you have been very kind
S30Uploads: i recognize that pond, do you know 4mods?
julie bery: Hello I shall like the reference of the helix thank you I have to find the
boat on hobbyking the esc and the engine but I find not the helix Sorry I
am french thx
Boot2yourHead: Franky she move, now how the heck is that motor still good I thought they
were done if they got wet. guess i have to rethink brush less motors.
catamaranman333: Also, have you thought about using a check-valve in the drain holes so if
you do get any water in the hull it comes right out (as long as you're on a
DiehardRCaddicts: Well I see your problem clearly now. 4800kv is about 3.5 times more than
the stock motor which is 1400kv. The stock prop is way to big and that is
what killed the second motor. Your lucky if you didn't burn the esc too! If
you are going to run a 28mm diameter motor with the stock prop you will
need to stay around 1400kv. If you want to run a high kv motor, you can go
up to 2800kv but would need to go down to a 35mm prop.
Chris Wyatt: i want to to the upgrades but keep the look of an actual boat outrunner any
Mick Bet: hello where did you get the parts to make the outbaord
jdgurl143: where do i get a replacement flex shaft, and drive dog, and collet?
Anuar Razak: Thanks - But it is going to be a bit difficult to find a 1600kv with a
shaft size of 3.175mm - Don't think HK carry any of those
mozzy72: Back in the day of racing off or on road cars on brushed motors, we used to
break them in on a 9V battery with the motor sitting in a glass of water.
How else can Traxxas say that their cars are ok to be driven in water?
DiehardRCaddicts: @traxxasinsane1 yes it will work fine with an inrunner motor. Actually if
you buy the ready to run outboard from Fullers Fast Electric it comes with
an inrunner motor on it.
DiehardRCaddicts: @jdgurl143 links to all the parts used are in the video information bar
below the video.
RIPcombat: 6s up front hang on. I no you have to try it
dioncuda .: man, that thing has alot of bite:)
DiehardRCaddicts: Could be a lot of differnt things.Examples: New motor kv is too high for
stock prop size, not getting good water flow for cooling, prop shaft not
lubed well and is binding, running too many battery cells for the setup,
the prop is too deep and causing too much load, the drive angle is wrong
and causing the boat to plow which makes the motor have to work too hard.
Check all these things
steg140: excuse me, I burned two motors with this boat, the stock one and a new one
which had the same dimensions as the stock one. before the second run I
even changed the esc to be sure it could properly match with the engine,
but it fried after 1 minute...can you tell me what's wrong?
DiehardRCaddicts: Not sure which shaft you are talking about. If you mean the 5mm motor shaft
it is the stock one only cut shorter to fit in the lower leg. If you mean
the flex shaft or prop shaft at the bottom of the drive, I was using the
stock ones that come with the Fullers Fast Electric lower drive leg. You
can find them on Ray Fullers ebay site. You can find a link in the video
information bar below the video.
VitorHugoz: Hello , i d like to know if doesnt problem with the water in to the motor .
I have a Hornet and burnnet 1 motor . could you please , can you help
me???? best regards
Natalia Saavedra: ok thanks. How did you angle your boat with this new mount? Did you raise
the motor up or down?
Linoge279: thats a good speed for racing and whats the runtime with that motor?I
didn't expected the tunnel ran that fast, you should mod more of this
tunnel and sell it, should sell like hot cake!!
DiehardRCaddicts: @stratosFZ1 the Fullers lower leg unit comes with the flex shaft and prop
shaft and swivel mount already installed If you have any questions be sure
to ask Ray Fuller on ebay before ordering, he is always a great help.
catamaranman333: Oh, one last thing.....that pond is shrinking.
DiehardRCaddicts: I got the outboard drive from Fullers Fast Electric. Please check the links
in the video information bar below the video. The Fullers lower leg unit
comes with the flex shaft and prop shaft and swivel mount already installed
If you have any questions be sure to ask Ray Fuller on ebay before
ordering, he is always a great help.
DiehardRCaddicts: The motor mount allows adjustment of the motor angle and height to fine
tune the ride additude of the boat. My boat hooks like yours if I turn too
sharp too fast. You can stop this by putting an inward angled turn fin
under the hull against the right side sponson at about the cg. Or you could
just adjust dual rates in the steering on your radio so you don't turn so
