Those are some nice propeller/engines you got there... "smeagol thinks they look very nice" :)
What are those?
they're cobra motors. i mostly fly with NTM PropDrives now, but those little green cobras perform beautifully. props are GWS 8x4s. i've made quite a few changes since this post (which are up on my blog mikeestee.com/blog), and my friend joachim has gone even farther with the cardboard tech:
I was interested in using NTM but there are a few negative reviews on HK, not sure what they are worth (the reviews), but they look well built. Have you had any problems with them?
Anyway, fantastic work!
