Zenith 750 Super Cruzer – Aircraft of the Month

New at Airventure 2026 Zenith debuted the Super Cruzer.

https://zenithair.net/zenith-ch-750-super-cruzer

Out of all the aircraft offerings out there, the 750 Super platform looks like one of the best way’s to go from what I can see, here are the factors in the equation:

  1. New aircraft with decent payload capacity, think PA-28’s C-172’s are now past 1/2 Million, the Cirrus and Diamon options are in the 1 million range = total fantasy and disconnected from the “common man”
  2. The “affordable” certified Cessna and Piper options are now 50 – 70 years old, many with a 6 figure price tag with lots of training fleet wear and tear and recent FAA mandated spar corrosion inspections that can total the air worthness of the wings in one test. part of the higher corrosion issue is the use of 2024 aluminum, the standard of the industry but the copper alloying element is very prone to corrosion, requires protective coatings from the start, maintenance of that coating and as is becoming more evident no air frame material is immortal, so the “just by certified” token advise has some holes in it.
  3. The next angle is the stability of the company behind the aircraft for parts & engineering support. Piper actually went bankrupt and shut down the factory in the mid 90’s, Cessna turned the ship to focus on corporate aviation at the same time.
  4. On the home built side the gold standard was Van’s RV, like a Dewalt tool nothing bad was allowed to be said about them. They make a great product, lots of confidence in the design BUT…………. taking the post Covid hit’s in 2023 they went into chapter 11 bankruptcy, fortunately they are still in business after the restructuring. Following not far behind them was Sonex, that also makes one good plane, skipping the chapter 11 option they where a few weeks away from a chapter 7 event and where saved at the last minute.
  5. When it comes to the kit plane market metal aircraft have traditionally been better at re-sale compared to composites or tube and fabric
  6. General materials vs the environment, wood and fabric rot quickly, composites can be more difficult to detect damage and must be protected against UV light.
  7. Getting a kit plane finished, plans aircraft turn into a long drawn out event, super complex aircraft are the enemy of schedule and budget.
  8. So far nock on wood Zenith has been “Cruzing” slow and steady past all of this, no one is immune but all totaled is a confidence indicator when spending tens of thousands on just the kit.

Based on the 750 Super Duty STOL champ with different wings and flight control surfaces. Its the same idea as the smaller lower power 750 to 750 cruiser that came out in 2013 The 70x platform has been out since 1986 giving a 40 year legacy. Modern Zenith kits feature 6061 aluminum construction with CAD & CNC matched hole construction.

Back at Airventure 2014 the EAA hosted a one week build of the smaller Cruiser = https://www.eaa.org/airventure/features-and-attractions/aircraft-areas/homebuilt-airplanes-area/eaa-airventure-oshkosh-one-week-wonder/oww-2014

the array of 70x options can seem a bit confusing but it comes down to engine size and useful load:

Original 701 designed for a 50 HP Rotax 503 & 960 lbs gross, the later SP option added fuel & a 1100 gross

STOL 750 came out at Airventure 2008, designed for the light sport rule with a 1320 gross and much more common 100 ish HP engines including the o-200, Corvair, Rotax 9xx, Jabiru and others

750 Cruzer came out at Sun n Fun 2013 and was the first de-STOL-ing of the platform with the removal of the fixed slats, a conventional vertical stab and symmetric horizontal stab.

750 Super Duty was up sized and modernized to allow for 180 ish HP engines focusing in on the O-360

750 Super Cruzer does the same de-STOL-ing treatment with the same engine and fuselage.

There was a larger 4 seat version called the 801 that is no longer in production.

No RC options I could find

Wings over the Rockies Aviation Museum

I recently got to visit the Museum on a trip to Colorado, very impressive and well worth the visit for anyone who likes to see historic military aircraft.

Of special interest my Grandfather worked at Lowry for a few decades working on various simulators, training aids and general handy man for the USAF. Going through old family photo albums here is a picture of him (centered) receiving an award from one of the AFB leaders

FrSKY X20 Case Upgrades

I wanted to upgrade my carrying case for my new X20HD from the soft wall case to something more heavy duty.

1st up the foam insert for the provided case is really good, way better than pick foam so I needed to work around that.

1), the case

I found the modern solution in the Harbor Freight Apache cases, and foam insert fits inside the 3800 model

https://www.harborfreight.com/3800-weatherproof-protective-case-large-black-63927.html

Sometimes they offer coupons so be on the lookout.

There are some alternate online options but the size may be different than what is covered here

As for the hinge to handle direction there was a 1/2″ gap so I used some high end packing foam in a nice dark grey from my Creality Ender 3D printer for that

Speaking of witch Creality is my go to for 3D printing equipment, its worth checking out

Creality on Amazon = https://amzn.to/4kkC20b

A recent review of the machine that did the 3D printed parts on YouTube:

.

.

2), maxing out the foam insert space

The next part in the puzzle was the 4 in 1 module I got to work with most of the protocols out there,

For this I picked the iRX4 Lite from iRangeX = https://amzn.to/4k5ZMF6

I had to cut out some of the foam insert for this to fit. I’m surprised that FrSKY did not already have this area opened up as it would save them foam / cost and weight.

.

.

3), interacting with the X20 Screen

While the X20 series is amazing technology and the screen is something to behold its also alot of small menu selections for average fingers to interact with.

For this part I found a good stylus on Amazon that works well with the screen and makes it easier to use = https://amzn.to/4qcRAoe

.

.

4), protecting the screen

I wanted to cover the screen while in the case or just when sitting out side, also needed a way to hold onto the stylus in part 3), enter the cover

Designed in Rhino 3D one of my favorite Cad Programs this easy to print cover takes around 1 hour on a modern core xy machine

I had to put the FrSKY logo on it because why not, with that in mind I have it up on Thingiverse for Free = https://www.thingiverse.com/thing:7285780

.

.

5) filling the void

I still had several inches to take up in the Apache case so I decided to make a storage box for anything related to the X20,

The lids I went to town and made them have an ISO grid pattern as its stuck in my head after working on Aircraft Gas Turbines for a lot of my career. Also has a kind of NASA Equipment look to it. Silk / Metallic filament is a must for this!

May be an image of waffle iron

I have the .3dm & .stl files up on Cults3D for this one: https://cults3d.com/en/3d-model/gadget/frsky-x20-and-hft-apache-3800-storage-box

For all the 3D printed parts I used my go to brand Sunlu available with quick delivery from Amazon

Bell X-22 – Aircraft of the Month

https://upload.wikimedia.org/wikipedia/commons/0/0f/Bell_X-22_ducted_fan.jpg

The Bell X-22 was a ground breaking VTOL aircraft developed in the 1960’s and flew up to 1984. 2 of them where built and beyond the pivot mechanism featured some similarities to modern day quad copter “drones” While purely an X plane lessons learned from this program made it into modern production VTOL aircraft. https://en.wikipedia.org/wiki/Bell_X-22

Its one of the few X planes I remember as a kid getting into aviation. I’m sure James Cameron was inspired as well as the fictional SA-2 Samson in Avatar and the HK-VTOL in Terminator has a similar appearance.

One thing holding the design back is modern P.I.D. control logic hardware was just in its infancy back when this aircraft first became operational. P.I.D. is now the cornerstone method in electronic stability and control seen in modern unmanned drones. https://en.wikipedia.org/wiki/Proportional%E2%80%93integral%E2%80%93derivative_controller

Quite a few YouTube Videos on the X-22

No hits on Outerzone or Amazon.

With modern Drone components and 3D printers I’m sure creating a functional scale model would be quite possible for a crusader willing to take on the challenge.

Seawind – Aircraft of the Month

The Seawind is a unique Sea Plane that first flew in 1982 and was offered as a kit plane up to 2002. Direction shifted to a certified version but the 2008 recession ultimately took it out with actual efforts ending a few years later

The original Seawind 2000 had a 200 hp IO-360 followed up with the 3000 that had a 300 HP engine. Over 80 kits where shipped and they do show up on the used market.

Despite it’s high mounted engine power vs pitch dynamics seemed to be manageable.

Wiki has quite a good overview of the history: https://en.wikipedia.org/wiki/Seawind_International_Seawind

A quick google search found the super sea wind web page for N71RJ a Seawind that is powered by a PT6

https://superseawind.com/

https://generalaviationnews.com/2016/04/26/building-a-super-seawind-from-arms-to-wings/

Living in Florida and being around the LoPresti operations at KVRB I found out LeRoy designed a seaplane called the Spectra that had its first flight in 1969 that appears to be the genesis of this kind of vertical stab mounted engine sea plane. I’m sure the Seawind designer(s) where aware of the Spectra and where influenced by it.

undefined

https://en.wikipedia.org/wiki/Island_X-199_Spectra

Quite a few videos on YouTube;

Lots of RC options as well:

For RC options:

Tower Hobbies offers a 1.4M Seawind

https://www.towerhobbies.com/product/seawind-1.4m-pnp/TOWA1575.html

Flyzone also offered a an option:

https://www.modelaviation.com/flyzone-seawind

two other RC sea plane designs have a similar vertical stab mounted engine setup:

1 The Spectra mentioned Earlier:

    2. The Northstar designed by Laddie Mikulasko in the March 1986 issue of RCM as plans:

    https://outerzone.co.uk/plan_details.asp?ID=10325

    Balsa USA has continuously offered a kit for the Northstar that’s still available.

    I built one back in the 1990’s and it flew fairly well: https://balsausa.com/products/northstar?srsltid=AfmBOopjFQAEr7TWaSCdZgN37gC06TKxePNcTOZGayMkhsPRindB8W9U

    There has been quite a few all foam / ARF based versions inspired by the Northstar that have come out in the years after the electric aircraft revolution of the mid 2000’s
