Dynam BF 109 Motor Replacement or upgrade options

Hi all I have been looking for a more reliable motor for my Dynam BF 109, and I could use some help in finding one. I searched the Dynam BF 109 users forum for alternate motors but I couldnt find anything on this. If someone else has a link to a Motor that would be a better/ more reliable upgrade or replacement please sent me a link.

This page has a little info on the NTM 42 750kv we have used.

Currently running sk3 42 740kv in my 109

Both require a little tweaking and a bigger esc.

Check out the Dynam hellcat thread as well for motor options.

I'm dusting my 109 off for the winter flying season

Yes. The NTM 4238 - 750KV is a great motor for this bird. It's a drop in fit using the Dynam motor mount. You do need to reverse the shaft to use the stock spinner. I did a video on how to do it. It's easy. I have this motor in my Dynam BF109.
