Gals and Guys,

================================================== ===========

After perhaps three months after purchasing the newer (used) Strut / Spring / wheel hub assemblies from Bavarian Auto Recycling in Cordova, California

I finally got my 1987 BMW 325i Convertible over to my family friend's house and thinking it was going to be a several day affair and instead (just like the rear shocks), it was a piece of cake and just under 4 hours and taking it easy and with a lunch in-between.

I just don't understand why people bad mouth BMW's and the cost of parts but, even the new shocks, bearings, and most especially brake components (new) are less expensive than my Toyota Camry! Of course I am talking about a 28+ year old car and realize that the new ones have lots of sensors and computerized items but, so does the other brands (Toyota, Nissan, Mazda, etc....) and ALL of them are pretty expensive to repair.

My experienced with this 28+ year old BMW Project has resulted in an appreciation of GERMAN automotive Engineering. The front struts were very easy to take out and replace as one complete assembly since I purchased the pair of Strut Assemblies that came with a 6 month warranty certification from Bavarian Auto Recycling and true to their word, my BMW sits higher (Factory Specifications) and with...Continue Reading

Big success!

Since Elevator control horn was at its maximum deflection position, had to take off the wing and adjust the push rod at the servo arm to the outer most hole.

Also, I drilled additional holes but, the Rudder Control horn was the only to benefit.

Just an amazing spin action!

So much so, that it will give you two additional spins after bringing the control sticks back to zero.

SPIN ACTION SUMMARY:

This took Trial and error.

The main success key was to change the Elevator Servo Arm - Rod to its outer most hole and this allowed the model to SPIN with gusto. I did not programmed any D/R or Expo on the Elevator and I was able to have Full Control.

The Rudder Control Horn Clevis did use one of the newly Drilled Holes on the Control Horn for maximum Rudder deflection.

THEREFORE:: The Vortex Generators has nothing to do with this Sport Cub not being able to perform a SPIN ACTION. Additionally, my conclusion that similar Airframes are just that......

A CUB "IS" A CUB no matter what and it will SPIN!!! There is no ROCKET Science in this......just enough Elevator Deflection & accompanied with enough Rudder Deflection is ALL THAT is needed.

Some information for those that would be interested in how it works!

As far as getting flatter SPIN would be with the smaller 1300 batteries since using the 2200's in the far AFT position still results in a slightly nose heavy Center-Of-Gravity.
