Genisis...

[SirBudman32]

I have the Genesis hull as well, Running CC1515 2200 T-180 2 5s 5000's. temp's ok till I tried a 642, didn't like that. With a x440 3blade boat just don't seem to get up and go like it should.

[HYDROJERRY]

yeah i tryed the 642 and seemed like it had lost alot of power, i have a new GR 40x52 im going to try also,,, the boat has that pulling to the wright thing so im trying to cure that, yeah i hear the CC motors run pritty cool and leopards run worm..

Viper1, I think your choices are fine. That particular motor seems like a good upgrade over stock and don't let the personal feelings of some on this forum sour your taste for the Turnigy brand. Some guys just can't resist knocking something for what ever reason, offen for no real reason.

As you can tell from various youtube reports the Genesis is capable of some really high speeds. Is it the perfect boat? Probably NOT. No question it is one of the better looking boats. Reagarding your desire to break 63 mph. You can do it with this proposed setup. Yes the M series Octura prop is basically a detongued X series. 5S might be your better choice over all for that motor but 6S will heat up your electronics and perform well just let the revs do their work and don't over prop. One obvious short coming with the Genesis is it is very narrow and I find 45mm diameter props tend to show sensitivity to torque roll. I know at least a dozen guys on this forum that would like to take that Aparition boat in the video you linked and adjust the setup and out perform the video big time. By that I mean there are a ton of small things that a knowledgable boater can do to improve performance and moving the GPS and batteries just touches the surface. My best advice be sure to raise the strut above the flat surface of a table. I do not mean the center line of the shaft either. The bottom of the strut needs to be above the sponsons when sitting on a table.

Now take this remark in the spirit it is given. If you are set at running 63 mph on a normal basis start thinking now about what your next boat will be. The Genesis will not hold up at those speeds....without reinforcing the hull. But heck, that is what we do. Run them until they break and then rebuild, reinforce, redesign and replace.

Parting remark. I upgraded my Genesis several times now and I have settled in on a 2100 watt 4074 2000KV motor running 4S most of the time. I use the same Turnigy 180 ESC and I know I can break 60mph easily when I change out the motor to a 1640 KV Castle on
6S, but I am pretty happy running in the high 50's.

"Just" a Hobbyking motor, so that makes it per definition bad?

Hey Viper dont think that HK stuff is junk, yea its not a 250.00 castle, but a good motor just the same and a great motor for 40 or 50 bucks, half the boats on here have turnigy T 180 esc's, where to they come from, HK thats where. If your on a budget and not in a hurry I think alot of stuff they have is good, some stuff, such as mounts and flex shafts and props, I would get better stuff over here from OSE or KINTEC. I get my stuff from every where, Shawn.

[Spencer154]

I also own a genesis, im running a leapord 4092 1730kv with a swordfish 200 on 6s. Ive been right around the 70 mph mark.

Two 3s packs or two 6s packs? What kind of run time?

Thanks Dave,

After 30 years in the hobby you learn a lot, (as you would know...) One of the things is that there are hobbyists and "trend followers" as I call them.
I am quite open minded about any brand and would not have achieved as much as I did in this hobby/sport if I would be one of the last kind.....
Admitted that a while ago some HK stuff was a hit & miss sometimes, Things change.
If you take the Li-Po batteries for example they are 'up there' with the best, and if you take it a step further and include the price as a factor, they smash any brand 'X' or 'Y" and that's a fact. Years ago you had to buy a $200.00 pack from 'brand X' to be accepted by the electric community. I still have them laying around somewhere, for low demanding applications :-)
Just lifting out an example, I shop everywhere and have no preference for any brand or shop.

I know the 'Genie' (that's scary, I think I'm in love ) is not a perfect boat but I agree she's a looker. Regarding hull strength, I plan to reinforce it anyway at least in some strategic areas like shaft, transom, battery, motor & servo mount etc. with some CF cloth. Maybe even the whole inside but hard to tell when I don't have it here yet. We have to try to make it as close to perfect as possible right :-)

Regarding the strut, no..first I should ask: Can I keep it when I upgrade to 3/16" shaft? I am able to machine or modify some parts if necessary and I have a small lathe at home.
Regarding strut setup, I've seen side-view photo's where the strut is <just> sitting "off the table" is that what you mean? And raising the strut will keep the nose down correct? Could you elaborate more on how the strut settings affect the thrust force and attitude of the hull and why as I don't understand that part yet? Any links where these basics are explained?
Did you sharpen your strut on the top of the leading edge, in other words extent the V-section higher up? looks like it in the pictures you posted in post # 51?

Prop/Battery:
I start to lean towards a 5s and the M442 to start with. Reason I keep asking is that ideally I would get a bunch of plastic props in different sizes, experiment what works, and buy that prop in metal. Metal props are too expensive for my budget to buy many. But the catch is that the plastic props doesn't seem to hold up for long, not even a decent test run on this power level.

I also have a HD GoPro camera (used on previous page in this thread in the rear view footage by 'Paultbg' ) and am certainly planning to take that aboard as well in later stage. I found that vid and especially your analysis very helpful in the comments towards that video, and now notice same details in other posted video clips of the Genesis. For example the vertical spray (leakage between bracket and strut).

Highly value your opinion,
Thanks a lot

Thanks Shawn,

I agree, sort of covered that in my previous post, for what it worth. (And they are just opinions right?)
By the way the HK 180 is a re-branded Hobbywing Seaking ESC, see http://www.hobbywing.com/product_show.asp?id=219

OSE would be brilliant for a one-stop harware source but the shipping to Australia is just insane (over 20 bucks for a $10.00 collet?)

Found these CNC props which are -quote-: " OCTURA INSPIRED DESIGN"

http://stores.ebay.com.au/VXperformanceproducts/Fast-Electric-Props-/_i.html?_fsub=2590827017&_sid=456345287&_trksid=p4634.c0.m322

Whadaya guys think? they look well made, pro/contra's re material compared to berillium/copper ?

I like them myself, they dont need any further B and S wich I like and have some counter rotaiting choices for that twin your gona build down the road vipe.

Of course love....

Sorry, just practicing for when she discovers the box.....

[Maciek74]

i think i just fried my ESC (turnigy marine 180A) i hope engine survived, is there any way to check if this is ESC broken other than connecting new engine to it?

Maciek

[stadiumyamaha]

What's it doing. Normally a esc won't take out a motor but the other way around will happen.
Kv, prop, batteries?

[Maciek74]

it suddenly stopped, Leo 3674 1700kvwas warm as hell (ofc batteries in thermometer were unloaded :) ) and 3 cables from motor almost melted, i connected another motor, no reaction, prop was x445, batteries 2x6s 4900 25c, air temp 28deg.
water was really flat so i think i overheated it from speed...

i think i need bigger motor.

[paultbg]

solder again the bullet connectors in the motor and esc side (all 6). probably one of them is melted.
it is hard to kill this combination, leo+t180.
