This decision proved to be a very big mistake. Just before the landing on the downwind leg something caused the big model to enter a nose down spin dive into the ground. The crash smasher all the plywood frames into many pieces leaving the fiberglass fuselage resembling a limp and gutted form.
There were several buckles and creases and numerous cases where the gel-coat was cracked or missing. I was of a mind to scrap this war-bird, but one of my internet buddies urged me to repair to flying condition, arguing that the zero was one of his favorite flying models.
After a reasonable cooling off period I had another look at the wreckage and began considering repair options.
The wing was still in one piece and except for a 3/4 inch gap at the trailing edge where the center-line joint partially separated.
Additionally there was some leading edge crushing at the fuselage intersection area.
The trailing edge separation issue was dealt with when epoxy glue was squeezed into the crack and a cargo strap, hooked into the aileron cutouts was used to pull the wing halves together. A cuff of fiberglass at the center-line joint added another level of safety over the stock ARF condition.
The leading edge crushing was fixed by filling the low areas with expanding foam, bringing the area back to profile by carving and sanding away the excess material. The areas were finished by over laying the surface with a single layer of epoxy filled fiberglass.
Since the paint and surface finish was already in bad condition from hard use before the crash now after it was so bad that it was clear that the whole model would need to be refinished.
With that decision we began the search for an alternative color scheme. The dark green color was always a problem with disability at low altitude when the model was back-grounded against the trees and other vegetation it was very hard to see. With that in mind we settled on a light grey Navy color scheme with as much bright trim as we could find.
Wing weight is 2.17 Kg.
The decision was made to experiment with using latex house paint to cover up the existing finish which had not been found to be hot glow fuel proof and was softened or missing in several areas that were exposed to engine exhaust.
The grey color was achieved by mixing white with black, ever mindful of the fact that there would be no going back; very small amounts of black were added and tested until we were happy with the result.
The yellow and red trim was added by apply strips of Mono-Coat covering material to the fiberglass structure
During the repair process we took the time to examine the rudder linkage which is rather unconventional with several locations of backlash and questionable geometry. The axis of movement if the torque rod did not coincide exactly with the rudder's hinge line. The results were a rather vague and weak rudder incapable of reacting the aerodynamic forces upon it at large pilot inputs. At this point we concluded that the model was flown in the past effectively as a elevator and aileron system with little or no rudder influence; meaning that there was no chance of recovering from a spin if one were to happen.
To correct the weak rudder problem control horns and pull-pull cables were installed to connect the rudder to the rudder servo.
First the torque rod was cut off with a dremel tool and removed then the fin was filled with expanding foam to anchor the new rudder hinges and stiffen the vertical fin
Right and left controls installed at the base of the rudder.
Pull-pull cables threaded through the fuselage connecting the rudder control horns to the rudder servo.
The cables are attached to inner Ny-Rod tubes at the forward ends, this is done to simplify the adjustment of length of the Pull-pull members.
Dry weight of the repaired plane is 7.00 Kg or 15.43 pounds.

We have a bad feeling that we may have just stumbled across the real cause of the mystery crash. While setting up the controls we accidentally plugged the left hand wing servo into the receiver's aileron channel and the right one into the auxiliary channel and low and behold we had spoilerons instead of the flaperons that we were expecting. Could I have made the same mistake on the day of the crash?
This video clip demonstrates that when the aileron servo leads are switched and the right hand aileron servo lead is plugged into the auxiliary receiver port and the left one is plugged into the flap port you get very different effects; spoilers instead of flaps and spoilers are something one doesn't want when setting up for a landing.
After working on this video I have a couple of more probable causes to add to the list:
Weather may have been a contribution factor as there were rail squalls in the area and the video shows her vanishing into a dark cloud at the moment of the tuck nose-down;
we may have sent her into the air with SPOIL-ERONS activated, we have learned that a simple mix-up with the servo wires causes this condition when employing the FLAP-ERONS configuration with the DX6 radio..

Upcoming Release of Canadian Aviation Regulations, Part IX (RPAS)
This document is intended to provide MAAC Members with some important information on the soon to be released regulations that will apply to UAS/RPAS/Model Aircraft.
1. The new regulations governing all Remotely Piloted Aircraft Systems (RPAS), which
include all aircraft operated without a pilot onboard, will be included is a new Part IX to the existing Canadian Aviation Regulations (CARs).
Note - Transport Canada will now use the term RPAS to identify all/any aircraft without a pilot onboard.
2. The new regulations will no longer differentiate between recreational use and non-
recreational use. This means that unless otherwise authorized, those operating model aircraft will have to follow the same regulations as the commercial operators.
3. Although the regulations are expected to be published before the end of this year, it
should be noted that the new regulations will not actually come into force (i.e. fully take effect) until approximately six (6) months after they are published in Canada Gazette II. Meaning that people are not required to follow the new regulations until they come into force date, which will likely be June, 2019.
4. Many of you may remember from the briefings Transport Canada provided last summer, that MAAC or similar organizations with established safety cultures were to be provided a "carve out" from the new Part IX regulations. Due to several factors, mainly timelines and Transport Canada resource issues, this "carve out" will now not be included in the initial release of UAS/RPAS regulations.
5. To address this issue, MAAC leadership has been working with Transport Canada to
secure an exemption to the new Part IX, RPAS regulations. This exemption will apply to all MAAC members, in good standing. With this exemption MAAC members will not be required to comply with the regulations in the new CARs, Part IX, provided they comply with MAAC’s published safety practices and guidelines and a few conditions in the exemption itself.
6. Once approved, this exemption will permit the vast majority of MAAC
activities/operations to be conducted as they are today. Details of the exemption will be provided to all members as part of an upcoming MAAC news letter.
7. The draft exemption is currently going through the final approval processes at Transport Canada and should be issued on the same day, or at minimum, very shortly after the new regulations are published in Canada Gazette II. This will be well before the coming into force date of the new regulations.
8. We hope you find the above information beneficial to assist with the transition to the new
regulations. More details will be provided soon.
9. Should you have any questions on the above information please contact your MAAC liaison to Transport Canada, Rodger Williams (rodgerwilliams9587@gmail.com )
