Upgrade motor from stock genesis motor

[tlandauer]

The Leo 4074, 2200KV would give you nice speed, just as a heads up, like post#2 said, it is really a 4s motor. 2200kv on 5s has unloaded RPM @ 40,700, that is high. I know first hand that people have run the Neu 15151y (2200kv) on 5s, but that motor's RPM limit is set at 60,000 RPM. http://www.offshoreelectrics.com/neu-motor-chart.htm
I have that motor in my Mean Machine although I run only 4s, it is a great motor.
The motor suggested by post #6 is also rated at 60,000 RPM, do not confuse the motor's rated RPM versus the so-called "unloaded RMP" when we select the appropriate kv motor, the guideline on the latter subject mainly concerns with the amp draw, the higher the RPM you run the motor with said kv, ( more cell count) the higher the amp draw.
I don't mean to offend you by praising these two motors and leave your Leo out, their bearings are of better quality and the winding, magnet and how the rotor is made all contribute to a more efficient motor, and that means less heat is generated "in the heat of the moment"...
My MG has a Leo 4082, 2200KV, before I dialed her in, the cat was already GPS'ed at 54 mph. That is just a drop in with a s/b'ed x642 prop, without any of the blue printing sponson and fiddling with the height of the strut. So enjoy your motor with 4s! You will have such a blast!
Cheers!

thanks for all that info, if that leopard motor doesent hold up, i will look into the neu 1515 1y 2200kv. I only have one set of the 5s batteries, so i will be mainly running the 4s. Just have the one set of 5s for the occasional bust of speed. Thanks again

Hey I just got a genesis also... Which flex drive did you buy for the upgrade? Does it require a new stuffing tube also or could I just slip the 3/16" in without having an issue?

i bought this http://www.offshoreelectrics.com/pro...?prod=ose-1190 and http://www.offshoreelectrics.com/pro...=oct-oc187t-24 and this http://www.offshoreelectrics.com/pro...dh-ks-brass-tb i ahavent installed it yet because this http://www.offshoreelectrics.com/pro...prod=ose-80975 is out of stock

[Cinnabun]

Ah ha. So you're going to replace the stuffing tube? I was hoping to avoid that because I'm really not great at fiberglassing yet. Not sure how I would feel about cutting the hull open on the genesis

dont think you have to do that, just make the hole bigger if it needs and fill the gaps with and exopy or silicon, thats my plan

The standard stuffing tube is ok I still use it. I just used a .150 flex (still has a 3/16 shaft) that allows you to still keep the standard teflon liner as well.
I still use the standard strut. I removed the stock bushings as there 4mm id. Used a drill bit (6mm) to drill in to them. You ony drill in a little and they catch on the drill bit then pull out. I then replace them with a piece 1/4 brass tube that I locktite in place and then use a floating brass bush the same as the speed master struts.

Will the .150 handle 6s power? And since I'm still new, could you link me to what I would need Ozzie? It would be very helpful

Not 100% sure on 6s. You can run .187 flex in the standard stuffer tube with no liner lots of people don't run a teflon liner.
Of to work will try to post a few links later.

[Cinnabun]

A .187 is 3/16 flex the whole way right? All I would do is rip the Teflon liner out? Obviously I would need to grease more often but I grease my boats after every day of running.

[ozzie-crawl]

Yea just remove the teflon liner. If ose does not have the replacment strut you can remove bushes and drill the strut out and add a piece of 1/4" brass tube. I just locktited it in. Then use 1 of these bushings http://www.offshoreelectrics.com/pro...=ros-spdsd-187.
