I am kit building a CH 650. While waiting for the wing mods, I have decided to work on the main gear (easily set aside when I get the mods). The 650 plans call for the main gear legs to be installed with the "flat" side toward the front. However, the Zenith demo plane and the HomeBuiltHELP demo plane show the gear legs installed in reverse. Is there a reason for this? Is this an old design? Are others doing this for some reason, or should I just follow the plans?

After having
positioned, drilled, and clecoed the upgrades to the center wing spar assembly, we now rivet the parts back together and bolt the two halves of the center spar assembly back together to reinstall it into the fuselage.
Here we begin to rivet the center wing spar assemblies back together using the "conventional" bucked rivets:…

The procedure I use to remove the AD-6 rivets from the spar for the upgrade is to first drill through the head with a 5/32 drill, shear the head off with a chisel, and then drill about 1/4" into the rivet with a 1/8" drill. I then use a 1/8" punch with an air hammer and push the rivet out.
The last thing I do is inspect the rivet to make sure that the drilling operation didn't go beyond the circumference of the rivet resulting in an enlarged hole in the spar. I'm happy to report that…

Continuing where we left off yesterday, now we install the mass balance to the ailerons. Since this was mandated by the
UK LAA earlier this year for Zodiac XL owners there, we used their drawings (which was engineered and tested by the LAA), as specified in the
AMD Safety Alert.
The aileron mass balance consists of an 18-inch arm…

With the main wings done, we now focus on the aileron upgrades.
The aileron upgrades consist of three separate items: Aileron gussets (65W2-5 and 65W2-6) on the aileron ribs, L-angle stiffeners for the aileron trim servo, and finally, aileron mass balance. Above, the right aileron is shown. Below is the left aileron.
Our demonstrator Zodiac CH 601 XL airplane has the original "hingeless" aileron system - many customers have the hinged…

Today I uploaded some pictures of the drilling Jig that I have made. This tool should allow safe accurate removal of the AD5/6 solid rivets as required to incorporate the structural updates on the 601XL/650.

We debur and rivet the aileron bellcrank support channel and stiffeners, and the rear channel doubler...
And we bolt in the wing root doubler 6-ZU-1-2 and rivet the nose rib angles (6-ZU-1-3 and 6-ZU-1-5) in place...
...and we cleco and rivet the nose ribs in place. Note that in the photo we are…

Now that we've installed all the upgrades to the first wing, we still need to finish a couple of items to the wing. With the wing skins clecoed back in place, we measure and mark off the 20 mm. hole placement for additional rivets into the inboard main wing spar (top & bottom):
We drill a hole between the existing holes...
Basically, we're doubling the number of rivets from the front and rear…

I am in the process of registering my CH 701 as a advance ultralight here in Canada. I heard back from Transport Canada today regarding my gross weight. I am trying to increase my gross weight from 960lbs to 1100lbs. Transport Canada will not allow this. I am aware that this has been done in the past. I have a letter from Chris Heintz dated Oct. 3, 1995 that the STOL CH701 may be operated at an increased gross weight. On Transport Canada's list of eligible ultralights allowed the CH 701 with…
