Genesis upgrade HELP

[Bagoboy]

very helpful thank you but i thought there would be sanding after the first layer is done?

what did you use to mount your motor and servo and if i am to replace mine what is the measurement so that i can put the mount in the exact position to line up with the shaft and is the linkage from the servo to control the rudder supplied by the boat manufacturer or did you purchase yours.I am going to use a Turnigy xk 3674-1900kv motor.

Need to change my stock motor ,it quit ,run 6s ,445 prop ,I have a 4072 2150 KV ,and a 4092 1600 KV ,want it a Little faster than it was ,which motor do I install 1st ? Don't want to get to the lake and have a slow boat ,isn't stock motor 2100 KV?

[MG1234]

So I got a 4092-1750kv,with a 445 prop ,not an M,it needs a little more prop ,ordered a M447, hope it's not to much

[Bagoboy]

how did you mount The ESC and servo

[MG1234]

Servo is zip tied into the slots made for it ,use a water proof ,esc is mounted in front of the motor,I used velcro from the hardware and zip ties ,the velcro helps keep it in place

Hi guys, I am a Genesis owner to. My flex drive diameter is 4mm and likewise with my drive shaft. Is there a way i could put bearings on my flex shaft and drive shaft to minimize drag?

[SD Eracer]

I wouldn't do that, I would instead buy a single piece .187 flexshaft/stub shaft. It makes maintenance & lubing a lot easier, and much stronger if you decide to add more power.

It will also allow you to use the most common props without the need of a shaft spacer.

You will need to remove the stock teflon liner, and purchase....

- .187 flexshaft $25
- 5mm to .187 collet $10
- Genesis .187 strut $15

This upgrade should be the first thing you do to your boat if you want to run it beyond the stock setup in the future.

i could not go to 3/16 cause i have got propellers already from 38 to 45mm with me and wished i could still use them instead of buying a new set of props.
So are you saying that bearings for the shafts are useless upgrades?

I don't know anyone who runs them on a flexshaft. Your strut is designed with a lead teflon bushing, I don't how you would install a bearing?

If you are running the stock setup on 4S, I really don't see any value in this type of mod. Even on my 73 mph Genesis, its just a single piece flexshaft which I grease every 4th run. I'm still using the same flexshaft for over 2 years in salt water and still looks new.

If you can find a 4mm single piece shaft, I would recommend that. It will allow you to grease your shaft easily without having to pull your strut off and/or remove your motor to completely grease your shaft and stub. Facilitating easy maintenance is probably better than a bearing mod.

Alright then I will forget the bearings. I was just comparing the boat with rc cars wherein every single moving part if possible there should be a bearing. You explained it very well and thank you so much. RC boats therefore is entirely different.

Travis (kfxguy) builds some fast boats and he drill's the strut out for bearings and machine's a groove in the strut for a snap ring to hold the bearings in. For most applications its probably not really worth it!

Another quick modification you can make to the genesis so it launches easier and handles better is to blank off the pocket under the rear overhang that drag in the water. I used thin clear plastic, cut to fit overlapping the pocket then super glued in in place. I also used silicone caulking to seal it tight so water won't get in. makes a huge difference and runs around 50 MPH depending on the wind and chop on the water.....
I am running the stock motor with the 3/16" flex shaft upgrade on stock 4s setup with a modified M445 prop. No more sharp right turns when getting up to speed...

Not to contradict you but I run bearings in 99% of my builds. The only boats I own right now without sealed roller bearings are my 26" shockwave (strut is too small to fit them) and my zelos twin (because the drives would be too hard to chuck in my lathe to machine for bearings to fit). Probably just useless information really but I personally like using bearings. Is it worth it? I'm not sure but the driveline is much smoother, quieter and has less slack at the prop. I'm not sure exactly how much faster it is either as I never really did a back to back test but I do feel that it's worth a little bit.

Also, I want to tell you guys something. I set a couple of these hulls up. One went almost 90 with a single and the other went 103 with a single. It likes the strut about 1/4" off the table with a 45mm prop (when the hull is flat on a flat surface). Abc 17* rake props like a touch of negative with this hull.
