I may pull the trigger on this one. Just a few questions though.... Can the preset Losi models be erased, or do you have to work around them? Also, does this unit have the same loose flap issue the DX6R has? I've read this unit is backwards compatible with DSM2 receivers; at what frame rates can these older receivers be bound at? And lastly, how does the screen size compare to the older, DX3R Pro?
Thanks
