I did my conversion as stated above, but using a 20 amp Eflite ESC and Futuba 2.4 GZ. radio and receiver, but when I throttle up I get to the half way mark and the motor begins to cut out, I'm also using the standard batteries for the Super Cub. What could be causing this, prop and motor makes a heck of a noise before it cuts out. Any help would be appreicated.

To windy out so it might be a few days before the test flight. |

Hey dbuck, you may want to see my post here; supercubclub.proboards78.com/index.cgi?board=motors&action=display&thread=1191458436&page=2I did the same upgrade that you did and the motor fried after about 8 flights. There was some pretty useful info given about the gear ratios and prop sizes you might want to consider. I'm sorry but there is a lot of off topic windsurfing talk too so you'll need to wade through that. It was definitely fun while it lasted, there was more power than I ever wanted with that motor. |

Be aware that the Cub is geared 3:1, the Typhoon is 8:1. If you use Cub gearing that calls for a MUCH smaller prop or you risk frying your nice new inrunner or ESC. (see Zeta30 note above and read ALL that thread).
Do a 30 second WOT static test and check for a hot motor. If hot (warm is fine) prop down a little. 10x6 is sometimes recommended for a more efficient (but less powerful) option to stock motors. It still could be a bit big for your application. This kind of hopped it up myself application is what Wattmeters are made for. Right now you are just guessing what you are doing.

Thanks for the imput, haven't had a chance for my son and I to go out and test, too windy, I'm going to buy a wattmeter to test. The prop we put on was a GWS DD 10X6.
