Looking at other designs of late, the sequence looks right on with the EF Vanquish.. That has proven itself to be very reliable flyer.
One could say the Vanquish is tech. an OLD name, but they didn't need to RE-invent the wheel. They tweeked the heck out of it..
The Sequence is a good 350$ less than the EF. I don't know anything about electric setups, but I believe the 2M setups use 10-12S LIPO???

I hope both are great flyers..... Although it would have been nice to see a adjustable incidence. for the wings/elevator....
