I couldn't be happier after putting in 6 flights with the new Divergent. The biggest difference is the adjustment to the fuselage layup. Final weight is just under 4500 grams. The other changes that were made were changing the rudder shape and making it taller, lowering the stab 1" and adding the ventral fin. The only adjustments made today at the field was moving the batteries as far back on the tray as I could and attaching a small wrench to the tailwheel bracket to move the CG back. While that was a big step in the right direction, it was still on the nose heavy side. In spite of that I was able to fly the masters sequence fairly well. There is zero roll coupling in knife edge but has a slight pull to the canopy which will be greatly reduced if not almost eliminated with the correct CG. It does slightly pull to the right on an upline. Before the next trip to the field I will take out some right thrust and maybe move the battery tray back 2". I really liked the prototype Divergent and it proved to be a very competitive airplane but with the aerodynamic changes and lighter weight this new one brings the design up to the next level.

I've got close to 30 flights on the new Divergent now and it keeps getting better each time out. As we all know, trimming a pattern airplane takes some time. Each change needs to be flown a few times to decide if it was a good change or not. The first change was moving the battery tray back to get a CG shift. Although that made a big difference, I think the CG could go back a little more. The reasons for this is that in knife edge and down lines she pulls to the canopy slightly. At this point I have only set up a mix for a little down elevator with rudder application. The downline pull is so very slight that it is actually quite difficult to see. No rudder/aileron mix is needed. The next change made was a reduction in right thrust. I went from 3 degrees to around 2.5. She wanted to pull to the right on uplines and in horizontal flight. So far I have not seen the need for aileron differential. She rolls very axial especially on up and down lines. Again I think with a little more aft CG the horizontal rolls would get easier.

Where from here? The next step will be to swap to a heavier tail wheel and add a little temporary weight to the tail. I want to see if this eliminates the need for a downline mix. I doubt it would eliminate the need for the rudder/elevator mix but I would be happy if it reduced it. If the CG change is benificial then I will be leaning toward buying 4500mah batteries. So far each run through the masters consumes between 2800ma and 3200ma depending on the wind.

Good to hear your results. I don't recall the exact difference in weight of each version but can you determine if the weight loss made a significant change? Also, still happy with the HV69 on rudder?

Could you also provide more information about the Zepsus Magnetic Switch. Is it the 7A version? Thanks.

Ted, this new one is 1000g lighter. To be honest I had expected more of a difference between the two because of the weight but they both fly so similar I would be hard pressed to say if the weight reduction is any benifit other then being legal weight. The HV69 on rudder seems to be quite happy. On Sunday I was doing several knife edge loops and Cuban eights, no lack of rudder power.

Yes it is the 7 amp version. I also have a 20 amp version in a 1/3 scale bipe and have had no issues.

Gotta say, that's impressive. Only hope I can achieve similar results. The switch is interesting as well. I've been using the Jeti Mag switch but it's way more money so I'll pick up a couple of those. I didn't notice any air outlets on the second fuse but certainly did notice the lesser quantity of inlets, think it would tolerate Fla temps in that configuration?

We got into the mid 90's on Sunday, no issues. The prototype started out with a Hacker C50 13XL that ran really hot. The cutouts were in effort to cool it down. That being said, I'm pretty conservative on the power. A more aggressive left hand may need more airflow.

I haven't updated the thread for a while. The new Divergent flew in its first contest a few weeks ago. Due to the current Covid 19 situation turnout was low. Between the low turnout and a few masters class pilots moving to FAI silver there were only two of us flying masters, both Divergents. I took first and my buddy Russ took second.
