super vee motor failure

[watto]

Thanks for all your input guys. I'll give the bearings a go first and see how that goes, just got a grim 3 blade so want to try it out before upgrading motor. As long as I'm faster than the mates nitro tunnel hull I'll be happy! I have noticed looking at pictures on the net that alot of the fe's run a pro prop thats clear red plastic looking, what are these? and are they any good?

[chuckc]

No, No, NO, plastic is not the prop.!!!! Co/Ba, Balanced and de-tonged. Might want to back cut alittle at the hub. I ran in the Nat's this year with a B/J with a 455 balanced, sharpened and de-tonged and it was well ahead of any SV27 on the pond, with a 6.2lb hydro. Never had temps over 105 on anything. Just my $.02 The boat is my avatar...

just got back from running her after replacing bearings and she runs heaps better and quieter but she flipped and I had to go for a swim! lucky its nice and warm here. Thinking about self righting chamber but what happens to the batteries? where do they move to?

I didn't get to answer you in time on your motor issue. I'm glad it's running good for you. As long as you haven't had any damage to the magnets or rotor then bearings are all you usually need to "rebuild" a brushless motor. Sometimes if the bearings let go and things start touching in there, then the motor will usually ruin it. Most brushless motor will last a long time if they are not ran too hot and modestly taken care of.

Yeh the motor did have some fairly decent scratching inside, mainly on the magnets but I thought I'll give it a go anyway after seeing how simple they are and she works like it did when she was new so pretty happy about that. Used rubber sealed bearings this time, got a set of metal shield as well as they were only $5 each. mine runs pretty cool now that I spray WD40 through the cooling system after each run it was getting hot due to blockage before this but shes all good now as long as I spray. My temp gauge isn't working but she wouldn't even be getting anywhere near 100 degrees since spraying can easily hold motor after run and batteries seem to be cooler aswell.
