It has built in failsafe, both for Rx low-voltage and radio interference. No need to get a seperate unit to plonk on your car.
It's menus are logical and has everything you'll ever need for car racing.
True but somebody here will swear that the Helios is better than 3PK !
I have to admit that the Helios looks good and feels more balanced when the antenna is extended. Feels more comfortable than the 3PK but the only thing I'm still rooting for 3PK is due to the large screen (eyes getting old) and fail safe function. Sadly, the 3PK is not as computer savy as the Helios. With the Helios, you're able to interface with the computer and save / upload your settings etc.
