THE STAINLESS STEEL ENGINE MOUNT


  

The new engine mount (nick named Madonna). After months of struggling Eppo’s team still

 

did not manage to weld the stainless steel mount in such a manner that the bolt holes for the

 

engine would not twist out off place. In the end four oversized pieces of massive steel were

 

welded into the frame (see left photo) and milled level. After that, drilling the bolt holes in

 

the precise spot was as easy as pie. Eventually this solution came from Eppo himself and

 

was and was implemented ( free of charge) all through the night by Jan Dekker of Forto.

 

       

Trevor Barker, a former KLM employee re-welded the entire mount. What a first-class job!


_________________________________________________________________________




In Ben Meelhuizen's hangar at Hilversum airfield the 80-hp 4 cylinder Limbach strung

 

up for a trial fitting in the new engine mount. The horizontal bars became the new

 

strengthened Seat Frame.

____________________________________________________





At last, the engine snugly fitted in its support frame. Yet to accomplish were the cooling

 

ducts and shrouds. The Limbach engine was not supposed to run above 195 Celsius.

__________________________________________________________________________


  

The cooling ducts and shrouds were manufactured by Stephan Haak. Unfortunately the first

 

set (left) did not live up to its expectations during trial flights in the US. The second set (right)

 

functioned to perfection. The bottom ducts, because of their outward tapering shape create

 

a vacuum sucking the air through the cooling ribs. Once again a solution by Eppo.

 

___________________________________________________________________________








DEVELOPING ADAPTATIONS TO THE EXISTING TRIKE FRAME:




Stephan Haak connects the hoof iron-shaped Reynolds-503 Seat Frame. It was a novelty

                      

that is was attached underneath the Base Tube, in a bracket developed by Stephan at KLM.

The Seat Frame adhered to the fuselage with epoxy raisin and strips of Kevlar

___________________________________________________________________________


  

To prevent cold air getting into the fuselage, the existing nose fork too had to be replaced by

 

the one on the right.

___________________________________________________________________________







DEVELOPING THE FUSELAGE AND TRIKE ADAPTATIONS:




Eppo draws the 1/1 basic design for the fuselage in his living room.

The 1/1 final sketch of the fuselage and trike frame adaptations.

__________________________________________________________________________





Franja Mora, a Yugoslav sculptor made the foam plug for the fuselage. Three months of

 

endless brainstorming, cutting and sanding resulted in a daily mountain of dust in Eppo’s

 

living room. But, in the end, it became an object of eye-catching beauty!

_________________________________________________________________________

The Final Kevlar fuselage weighing 7 kilos. Next to it the 21 kilo fibreglass mock-up to  

                                                       

decide where to cut the holes in the original so as not to prematurely spoil it.

__________________________________________________________________________





The fuselage attached to the trike frame. Yet to construct was the fuel tank, sculptured by

    

Gerard Engels out of a block of foam. Enveloped by fibreglass and epoxy raisin, once

 

hardened the foam was diluted with a strong solvent. Dolf Backer, also the manufacturer

 

of the fuselage could finish the job. (see photos below)

__________________________________________________________________________

____________________________________________________





Glue the lid to the fuel tank, clamp it tight with some foam and planks,

 

wait for it to harden, and oopsy Daisy ready to go! Or so we thought!

 

First time filling her up? Leaking life a kitchen sieve. Dolf sped to a

 

scene of utter despair. Did he fix it? The fuel cap even got a lock.

MECHANISM TO MOUNT THE FLEXWING ONTO THE TRIKE:




When all was ready to put the wing for the first time onto the trike, quess what, the

 

nose of the trike was too long for the control bar of the A-frame to pass. Eppo came

 

up with this odd solution at the end of the afternoon. The very next morning it was

 

functional. Don’t ask how! It always took three people to put the wing onto the trike.

 

(see photos below)


____________________________________________________________________




First place the wing at one side of the trike – then place the Pylon Tube with the hinging ball joint in the engine mount – now just lift the

 

wing and gently let the Pylon Tube slide into the engine mount – then turn the wing into the direction of flight.




Don’t try this at home, especially not with the assistance of two over-enthusiastic tipsy fellows at 4 o’clock in the morning by the head-

 

lights of a car. This is what happened to Eppo flying from Dayton to Oshkosh just south of Chicago in 1987. All is well that ends well.

THE FRENCH REGISTRATION – THIS IS HOW IT WAS MAILED





What an absolute feast to receive ones registration mailed in this manner. Eppo: “All

 

these years I have treasured it like a valuable collectable!” Concerning and considering

 

the enormous hassle it took to get a registration at all, please read below.

______________________________________________________________________







During the first meeting with the Dutch CAA (FAA) about the adaptations for his Atlantic ultralight it was agreed, quote: “if the English manufacturer would agree to these changes, then, as far as they were concerned they saw no problems in supplying Eppo’s craft with a Dutch registration.


The English manufacturer Roy Venton Walters and former BOEING aircraft engineer Nout van Rooy got to work. Roy even, on Eppo’s request and cost travelled all the way to Holland. Extensive reports were made and typed out all through the weekend and all throughout the night as well, thanks to Patricia Rens.


Unfortunately, at the time the Dutch Civil Aviation Authorities did not have the capacity to handle his two-volume rapport. Considering the ample time left, it forced Eppo to seek sanctuary at a local flying club in Maintenon France. Thanks to their efforts, Eppo got his necessary registration.





“Yves Berger, Bernard et Janinne Hariscain, my sincerest gratitude”

 

However it did force him to take all his practical and theoretical exams all over again. In French at that!
