Ron I have the 25c nanotechs, I know you are not big on them but they are working great, I'm testing them in this setup before I put them in my YA f-15 ARF with the DS-94 HST. They are holding at 3.43 per cell under serious load and late into an aggressive flight.
I'd love to see what numbers you get with these packs on your 1915 Dynamax! I was hesitant on the HET but I like that it is about 1/2 longer than the 1915 and it has sleeved magnets, I don't know enough about Steve' design on the 1915 but I have heard sleeving the magnets helps when you start hitting higher rpms like I'm doing with this setup.
Right on bud... that sounds pretty darn good. The price it just to hard to beat
I figure if I break them in, and treat them well the should do fine for me....
I wouldn't mine having a falcon to toy with.... but to many projects
thanks for the info... I feel a set coming in my future very soon
