Robinson Helicopter Model Compatibility
All R22’s built after 1995 have the 3/4” tow ball under the nose. All R44’s and R66’s have the tow ball. These are all compatible with the Robbie Tug RXXTC tow cart with some exceptions. The height of the top of the battery boxes is 13” and these extend under the nose. The drive wheels are also 13” in diameter but are mounted far enough to the sides as to not hit anything. Any accessories such as nose-mounted camera balls, FLIR, spot lights, etc., as well as antenna near the nose may interfere with the tow cart. Please assure yourself you have clearance under the helicopter for the tow cart.
Batteries
The RxxTC uses two Group 24 lead acid batteries. These are readily available from many retailers. Do not use Lithium batteries. The charger supplied with the system is not compatible with lithium batteries. In addition, the heavier lead acid batteries provide for better traction. It is recommended sealed maintenance-free AGM batteries be used but any Group 24 size 12V battery that meets the form factor will work.
The batteries should provide 5/16” threaded terminals which are typically found on batteries labelled as deep discharge or deep cycle, marine or RV, or marine starting. Terminal locations for positive and neg should be as shown in the image.
