Well, I watched the boat very carefully and thought maybe it was running a bit wet still, ajusted the stinger up a bit, got rid of the chine. I was really happy 'till i noticed she was kind of slow, decided to bring her in, about 3 ft. before me she stopped dead, I can see inside the hatch was filled with smoke. After carefully observing that it was not a slow fire , I opened the hatch, man, smells bad, but it was not the ESC!! rather the loose silicone cooling tube had bounced around and somehow got caught with the out-runner. Now my motor is damaged, do you know other than Venom who has these motors? They are out of stock and God knows when they will have them, these motor has a "collar" for the motor mount to clamp.

Hear are some motors that will fit the stock motor mount if you do not want to change it yet,
Better then venom and cheaper to.

Thanks for the links, I am waiting from Fightercat for some answer/advice, looks like he is out of the 2200Kv version, these motors look good, and is half the prize. meanwhile I soldered the plugs and put in the 120A ESC. I have those turn fins, not in red but in natural silver color. I have no intention to push the boat to exceed 50 mph and therefore I didn't observe any torque roll tendency. I like your idea of modding the battery position, I might consider doing that later .
As an aside, the fried motor still works, but you shoud see how it looks inside: as if been thru a nuclear attack. The windings are blobs!! lol...Too many boats, not enough time...Comment

Did you take the motor apart ?
If so,
May be with a heat gun and tweezers you could get the stuff off and still use it.
I think my temps were high because the x640 prop that came with the boat was not S & B,
I looked good at it today.lol
I will try two good S & B props tomorrow, A s215 and a m440.Comment

No, I didn't think about. That is at least a fun idea, had to work, may be later in the week. Sears, of all place, carries the motor, price a bit high.didn't have time to do more research.
Have fun tomorrow!Too many boats, not enough time...Comment

No dice, I took it apart after coming home. The blob on the windings is the burned lacquer on the copper wire. It only looks like a blob but will flake off when touched. Boy, the motor still turns, but I am not going to connect it again to electricity ever again, it is a very nice paper weight now on my desk! lol...
BTW, the quality inside the motor looks quite good, the magnets are still firmly epoxied to the casing of the rotor. All epoxy survived the heat, no discoloration. bearings are still good.Too many boats, not enough time...Comment

Hi Tom,
Do you know what your timing is set at on your old boat with bad motor ?
If not, May be you can hook the program card to the esc and see what it is set at.
The weather has bin to windy to run hear so I started modding some things again.
I added turn fins and modded the stock trim tabs / turn fin combo to just wider trim tabs,
It amazing what a hammer can do,
Next came making the stock rudder offset to the right,
And I will test higher timing setting on the esc and motor to see if they will run cooler or not,
Also made a seal for the hatch to lay on and one bolt and thumb nut to hold the hatch down.
I should try to reinforce the hatch to at some time, It just not to strong.
Now I just need to sink it and look for leak,
I will post some pictures of what I did so far.
I will test everything tomorrow.

HI Lenny,
I will check tomorrow, got to leave for work, Jamespl wrote on your other thread that Venom told him the timing is set at 11 deg. For your info, my motor was very warm, but my ESC was no where near your temp. I will see what the 60A ESC is set at. My 120A is set 15deg. But I have not run it yet.
Can't wait to see your mods!

Well I checked the 60A ESC that came with the boat, it is set at 15 deg. I wouldn't know if the previous owner has ajusted any of the settings. I decided the take the motor from my other NIB P1 and give it a run with the 120A ESC I put in a few days ago. The motor seemed to be more eager to rev up. Accel. from stop is stronger---there is no doubt about that.
Don't know if it is because of the ESC or the newer motor.
Temps were similar, with motor being on the warm side like 139-149 deg. Front of motor being the hottest at 160 deg., where the motor clamp is, pointing the temp gun into the windings the temp is lower:i.e. 139-149 deg. . ESC was never above 110 deg--not even at the cap side. Batt. were at 90deg. ( Gens Ace 5300mAh, 2s1p 30c from HobbyPartz)
x642prop
ESC set at 15 deg.Last edited by tlandauer; 02-22-2012, 07:03 PM.Too many boats, not enough time...Comment

Good to hear your back and running,
What speeds are you getting with 3s1p ?
When you ran your old motor before the tubing problem, Were you using the Gens ace cells than ?Comment

Thanks,
yes, I was using the same batteries. I am actually running on 4s. I didn't check the speed, last GPS reading was 41mph, 3s was 29mph. Today was similar. I thought it might have been a bit faster because there was a hint of chine walk again, I raised the stinger a little, now almost 0 deg. (neutral). It was by and large gone.
Post some pic when you have a chance, dying to see your mods.Too many boats, not enough time...Comment

Ok,
I was thinking the gens, kicked motor up.
My temps are down, I think it was the bad prop.
I try that again and see if they go back up.
Ran good today, And tried it on 3s1p 5 packs and best GPS 29.5 mph with a x442.
I forgot my new x642 prop, That will be next to try.
I put pack in center of boat all the way to back with the gps.
It drives great with the offset rudder, I move the turn fins up just about out of the water.
But that did not change how great it drives with the rudder offset.
