32" Mono Rec's.

Yo! I had a GREAT run with the boat!

My silcone job did the trick...Well for the most part. I killed off my whole pack of 18 cells, and there was just about a 1/5 of a dixie cup worth in the bottom of the hull. MUTCH improved.

Anyway, to the good stuff. EVERYTHING went great. I ran on 18 cells, using a worked P215 prop. Fan on the ESC, SV27 water cooler on the motor.

NOTHING was hot. Batteries, Motor, ESC all just barley warm. Maybe 100 degrees F. See, this is why I need my data logger to get here. For all I know I am only pulling 25 or 30 amps

The boat ran what looked to be consistent mid 30's. It was everybit as fast as my SV27 on 12 cells, and I think they would run together with the SV27 on 14 cells.....

So anyone think I should try a differant prop? I am happy with the speeds, but I almost think this quannum motor can push 40MPH. It does'nt even seem like it's breaking a sweat.

And thanks jeepers, i'm gonna check out that fuel tubing idea.

My props are as follows..

P215, P220, X447, X440/3,

Carbon 35mm -40mm -45mm -50mm -55mm

Bump! and more words cause it said I have to type 10 characters. :D

Jeepers do you have a picture of your strut and tubing. I am using a rubber grommet on the MM and there is not a drop of water getting n anymore. Stop the water coming in at the source, not after it is in the tube..... It works great.

[FE_Chris]

Watts, I like that. But I am not having to many problems with water so I am going to focus on other areas now.....

Just got my pistix. So now I can toss a p220 on and see what hapnnens. Still waiting on my 9xl....But I did get a x438 and a x440 from steven to try on the 9xl. So the pieces of my boat puzzle are slowly falling together...

I'll post back later and let you dudes know how it ran with the 220.

[FE_Chris]

Got a run in today.

Quannum 3670
18 cells
P220. Fresh off my balancer and sharpened right up!

First thing I wanna say. This boat ran good on the 215. No heat, good speed. But on this 220 and a x447 expecially, it creates heat.

I did'nt notice any speed increase going from the 215 to the 220. It only seemed to make the boat a bit looser out on the water, and got the motor hot. ESC was warm, and batts where warm.

Tomorrow I am tossing on a x440/3 I think. we'll see......

:D actually I stole the idea from you, but I didnt have a rubber grommet so i just used a piece of nitro fuel line instead, no water at all.:D

[hkusp45]

I think that 3 blade is gonna cause even more heat!!

Be carful!

[Jeepers]

Is this still the 1000 kv motor? in one of your posts you stated a quannum 3670. in another post you just stated that it ws a quannum 1000kv.
i am not familiar with these motors.

[ReddyWatts]

Jeepers, you did not steal the idea. That is why I post this stuff, hoping it will help someone or spark a new idea. Here it sparked the idea of using fuel line instead of a grommet. I am glad to hear that it worked for you. I have not been getting a drop of water in since I added this, except for the run this week that I stuffed it. ha

I have always had problems with some friction and water in the drive line. I found that the rubber grommet or your fuel line tubing on the prop shaft keeps the water from entering the tube. (I am not using any nylon tubing in the metal tube.) So without any water getting in the tube, I do not need all of the grease in the flex tube . I only spray some WD-40 on the flex and oil the prop shaft. I am seeing a lot less friction, resistance when turning the prop shaft after a boat run. This should give an increase in speed and lower your amps like a piano wire drive line. This is all experimental but has worked better so far.

You can only have one bend in your drive tube for this to work. It creates a bad vibration with two bends.

they are the same motor.....the motor has 1000KV and its dimensions are 36x70....

[FE_Chris]

Thanks wook. Yup same motor. It's the the 2 names it goes buy. Well...I'm gonna just have some fun with this motor and the p215 today, cause my 9xl and things are waiting at the PO for me to pickup tomorrow....And that means I need to start getting my props ready......

Thanks dudes....And i'll be back.

[FE_Chris]

Got my 9xl and all that in the mail yesterday. Got it all installed tonight. I wired everything with 4mm gold bullitts. And I got rid of a TON if wiring. I need to install a "good" water pickup still, and wire in the ESC fan. I should be rtr in the next day or so.

Whatcha think? I tried to make the wires as short as possible. Thats about as short as they get...

I am gonna shape up my x438 and x440 for the first test runs.

All I had gold bullitt's for was one set of battery packs. So I wired the 18 cells.

18 cells and a x438 is gonna be the first run!!!!

[seabassturd]

get ready for a barbq, 14 gauge wires 18 cells, i didnt catch what esc that is, but with a 9xl, it spells trouble. the fan and water cooling wont make a difference if you pull to many amps. ive torched 2 cc 80's with 12 and 14 cells, with a x440, and p210. which is 41mmx1.5 pitch. and the boat i'm mentioning was running very loose!! and with a well set-up drive train. i have a collection of 4 burned out brushless esc's and 6 brushed for a total of about $1700.00. so be carefull! it is a sweet looking set-up however!! nice work.

[FE_Chris]

You think maybe I should solder some 12 gauge wire on the ESC before I run it?

Screw it, it's a 50$ ESC, if it fries, i'll get a differant one.

[FE_Chris]

Ran it! on 18 cells and a x438. My 16 cells packs did not quite fit my wiring right, so I was like screw it. 18 it is!

I ran into one issue. It seems I have to make a better mark on the motor shaft for the setscrew thats on the collet to hold onto. It came a bit loose. I noticed when I got it in for temps. I'm gonna handle that here soon. I was not able to run it for more than a minute. And most of the time I was accelerating cause it was nuts and I could not keep the boat in the water!

This is what I did. I put it in the water trimmed just like I had it on the Quannum 3670 motor. Only change is prop and motor. One word. ROCKET! it was so fast I could not hold WOT at all. After less then 2 seconds it would purpose to much. I need to change the COG and trim tab setting's it looks like.

Motor was warm
ESC was luke warm
Battery's about room temp

So far so good, well... mostly!
