Hi,
if the frames would be the same, why we called it 550SX frame set?
.
There are minor differences between all frame sets (tail boom mounting, frame stiffener etc.) and of course the sets for LOGO 600 and 690 will follow shortly. But You have to start with one. So this is for the 550 only.
It will be available within the next days. The new frame allows a taller lipo battery, don't ask for the mm, I do not have any numbers in mind
, the weight difference is not worth mentioning. Including the frame stiffener it's only a few gramms, I will try to measure exactly.
If You take a look in You existing chassis there is lots of unused space at the bottom and also a few mm more to go. And even with the new battery tray there is much more space than before.
