I have a question. Since I had my first experience at indoor flying and the walls seem to move in on only me some problem came about on my little e-flite umx p-51D BL . When I throttle up it runs squeals then stops. Then if I throttle off it’s hit and miss if it works again. Could it be esc or the motor. Thanks Don.
Don did you hit the wall or ground ,sometimes the bushing jams up or check the gears are not damaged and make sure the prop will turn smoothly the squealing sound is usually from a binding prop ,could put a drop of 3 in 1 oil in the bushing could help .if it didn't make the squeal new out of the box something mechanical changed i really doubt its the esc that being said you never know let us know if you figure it out
i went to the web site were this video was posted on rcgroups.com the guy said his spinner was off center so he reposition it and it helped another person on the same form said this ( A UMX brushless motor normally squeals then stops when it gets jammed and draws too much current. Maybe the nosecone is too close to the fuselage and is rubbing on it. Maybe the motor bearing is too tight.) ,which makes sense to me ,the guy with plane also called HORIZON HOBBY and they sent him a new plane .About 4 years ago i bought a bad plane from SKYCRAFT it was impossible to fly the receiver was screwed up i called HORIZON explained my problems ,they sent me a new plane too i only paid shipping it was the umx p51 ,I forget what the shipping was but not to much and they let me keep the other plane for parts .it really sounds like the motor call the place were you bought the plane or call HORIZON good luck let me know how you make out
Here’s what I did. I grabbed another plane my wildcat unplugged the motor from the p51 and plugged it into the wildcat and it works fine, Then I plugged the p51 esc into the wildcat and it does the same as the p51. So I figure it’s the esc. It just makes sense. The only problem is that the esc and servos are all one unit and is more than 3/4 the price of the plane. So I think I have a donor plane now. I flew this plane many times in my back yard and helped me get my wings back this summer so here’s to the mighty mustang. One thing to remember is to make sure you use a throttle cut switch so when you crash it can be shut down fast. Just to many little things going on in there.Thanks for your help on this one Rick. Maybe see you Friday with my Pitts that I was saving up until I got brave enough.
glad you found the problem I will remember that one too, so many people having problems i get ask for help a lot, and more then happy to help them but you cant know every thing .Hope to be there Friday I have the Pitts really like it looks nice in the air you just have to stay on top of it or it can getaway from you i put lots of up trim so i can fly at 1/2 throttle i found the plane too fast if i don't
Admin: I am looking for an eighty inch Cub, made by Sig. I saw one at the swap meet in London, but got distracted and it got away from me. I heard someone stole it for a paltry sum of $175.00.

agn: The most useful tools I make are sanding bars. I use white pine wood of many sizes, if you have an old saw blade, cut them after gluing sand paper of different grades to the wood.Long ones short ones thin ones etc.

agn: I also used paint mixing sticks and broken propellers for compound curve sanding.You can use any glue but some need to be weighted to keep the sandpaper to the surface while curing/ drying.

agn: Also If you have a tube light , 8' is nice you can parallel the light with your work , a wing leading edge, sand and rotate it to check how the shape is working out. Longer blocks work well for this starting with course grain to finer grain sand paper.
