This option replaces the standard 'Y' center stick with dual control sticks.

I have the standard 'Y' in my 750 and I quite like it.  You get used to it very quickly and it makes getting in and out of the aircraft easier.

One benefit, I think, of the dual controls would be the opportunity to replace the 'push/pull' style of throttle control with a 'T-bar' style throttle quadrant.  The quadrant would sit in the position that is used by the Standard 'Y' and could be used from both seats.  I find the position of the 'push/pull' throttle handle less than ideal as when it is pulled out (idle and when shut down) it is easy to bump with your knee.

On the downside, dual controls add expense, complexity and weight.

The Zenith Dual Brakes Kit is a must-have if you plan to fly from the right seat, or if you plan on receiving instruction in your aircraft.  This light-weight addition includes all you need to upgrade any of the Zenith kit aircraft to permit differential and incremental braking from both seats.

James' note:  Again, this should not really be an option.  It's OK not to have a huge range if you are flying in NZ or the USA - Either you can't really fly that far or there's an airport every 20 miles.  If you are flying in Australia and you ever plan on selling your aircraft for a good price - then please do yourself a favour and include the Long Range Tank.

The extra 30 liters is pretty close to an extra 2 hours of flight time (depending on which engine you get and how hard you run the throttle, you should expect between 15 - 20 l.p.h).

These should be on every STOL aircraft.  They're cheap, easy to install and they work - please just get them or you are short-changing yourself on the best value performance improvement option out there.  VG's give a great improvement in control and low-end safety with no downside at all.

Vortex Generators (VG's) work by inducing mini-tornados (vortex's of swirling air) in their wake.  These vortexes help to keep the airflow effective over the elevator at much lower speeds.

They do this using magic and stuff.

Larger Aero-Classic “Tundra” tires replace the standard tires and fit the 6-inch wheels supplied in the Finishing Kit.  Sold as a SET (2)
The price is the additional cost for two (2) larger tires for the main gear.

The outside diameter of these Tundra tires is 53cm, versus the factory standard tire size of 43cm.

This is a pretty basic grey coloured fabric seats.  Honestly, I recommend you spend a little extra and check out the Lemke Upholstery package instead.  The newer upholstery kits from Zenith are very good, but this basic kit lacks any excitement.

These are very handy and work well.  They extend telescopically so they are compact enough to fly with if you ever want to do that.

The only problem with this option is that Zenith suggest you drill through your front strut (see photo) to insert the tow bar.

Check out the linked 'Skytek Towbar Attachment Bracket' for a cheap and easy to install option that does not need you to drill through the gear leg.  I have this on my 750 and it's brilliant.  It took me about 5 minutes to install as a retro-fit.

If you are installing larger tires, operating over long grass or looking for that extra-special steering bar attachment then this nosewheel spacer is for you.

Lift your propeller tips 50mm higher and further avoid wear from long grass and reduce the risk of a propeller strike on any unseen rocks or logs that may be waiting for you - especially if you have added large tires to the main gear.  Putting Tundra tires on the back will lower the nose geometry and reduce propeller clearance.

This tail skid kit is a great addition to your 750.  It doesn't matter if you fly a SD, STOL or a CRUZER - you will find this skid kit very handy.

Any time you like, you can simply push the tail down to the ground and leave your aircraft perched nose-high on the skid.  Very handy for cleaning or inspecting underneath.  It makes cleaning the top of your aircraft an absolute breeze - no more step ladders.

Did you know that with no tail protection the first thing to hit the ground is your RUDDER; not even the fuselage, but your actual rudder.  If you would prefer not to be worried about striking a control surface the next time you over cook a take off or move your aircraft then install this skid.  In colder climates this tail skid is used to protect aircraft from being dropped onto the rudder after a load of snow builds up on the horizontal stabilizer.  Even with the wings tied down this can happen.

It's a 5 minute installation with no special tools needed and all hardware supplied.  These are held in stock and ship immediately.
