Questions: IVOPROP Medium IFA

[Eric Page]

Thanks for the replies, gents. If you don't mind, how many hours do each of you have on your IFA pitch motors since they were repaired?

I've got the medium inflight prop. I've had multiple problems with my motor like mentioned above. Now not wanting to loose my prop because I love it, I stayed with it. What I came up with is that the rotosport uk ltd has a maintenance manual that goes through some things. not sure if it's in this or not, they might have a bulletin also. but simply put the white grease that IVO puts in these things is crap, simply said. What I did is I took the gears all apart and cleaned them with brake cleaner and put in new grease, there is another mentioned by the rotosport guys but I couldn't find it and put in Super Lube. that stuff is super slick. I also took the worm gear at the prop end and soaked it in light oil, you can't take it apart. than I lubed the screw end with super lube. I will tell you I found a profound difference in the working of the prop. much faster and goes all the way flat now. I think what is going on is the other, old lube is not good and causes things to bind so to speak and takes out the armature, it will also cause the brush connections to loose connection and even loosen up. very happy with my prop now, hope this helps. I also learned not to let the motor stop and blow the circuit breaker, I quit right when the prop stop changing on the rpm's. make sure your little gears have a nice tight fit on the center holes also.
