Hooked up with my brother to fish smallmouth on the Juniata
River in Mifflintown PA. This is day one, travel day from Lake Ridge airpark in Raleigh, NC, to our
destination, Mifflintown’s airpark.
Then on to the VRBO on the river.

Angel's Shadow V20 Bipe - Update
Man, time passes fast. In early 2022, I took delivery of an ASB (Angel's Shadow v20 Bipe). This was just before the Ukraine-Russia war broke out, freezing international bank transfers and shipping logistics. I'm very grateful my transaction was not impacted by the war. It was made ready-to-fly shortly after taking delivery. At the time, I was very happy with the BJ designs I was flying, so the ASB sat on the shelf waiting for its time.
Three years later, in September 2025 the ASB's maiden flight took place. The maiden was flawless. After a couple of flights and a few tweaks to flight parameters, the ASB was feeling fairly comfortable. The C54 swinging a 22x13 performed well, although I felt it was time to try a Contra system. Sent an email to Valdamir in Russia, the designer, enquiring about a new carbon nose to accommodate a Dualsky CRS3500. He replied yes and shipped it to me.
To date, 10 flights have been logged with a Dualsky Contra. Transitioning from a single prop to a Contra has a learning curve, both in how to fly the plane overall and how to set a throttle curve and use the throttle in flight. Currently, the DulaSky is swinging 22x20s F&R. I sense the need for more thrust and braking. The next flying session, the DulaSky will be swinging 23x20s F&R.
It is easy to recognize the ASB's potential now outfitted with a Contra. I look forward to logging more time and fine-tuning this setup to my liking.

BJ Craft Strato Trimming Continues
Last flights were 11/19. Besides being under the weather the last couple of weeks, I've been busy with life tasks, providing professional building services on new F3A planes for friends, and performing some in-house fleet maintenance. Today, the weather was too good to pass up. Went out to Bomberfield and logged flights on the Strato. Following the last session on 11/19, I remeasured the CG with the 10s 6k and 10s 5k packs. To my surprise, this repositioned the CG about 1/2" back from where I had been flying. Although this improved the feel on some elements, I'm still not completely satisfied. Between flights, I continued to adjust throws and expo to obtain the desired feel. After the last flight, I added one turn of positive incidence, which I'll test tomorrow.

Strato and Angel's Shadow V20
SE Texas Autumn weather is perfect for getting a jump start on next year's pattern season. Conditions on 11/19 were ideal for testing and continuing the trimming process for two of the newest planes in the fleet.
BJ Craft Strato
I wrote in an earlier post that the BJ Craft Strato has been a challenge for me to trim to my preferences. Even though, to my surprise, I've already logged 60 flights on the Strato, I'm still testing and changing setups. Most recently, I've added wing fences to improve the spin entry. Before the fences were added, when slowing and increasing the angle of attack, an unexpected wing would drop in a direction that wasn't planned. Adding the fences, along with mixing flaperons in the spin conditions, has made spin entries more predictable. The fences also improved the overall tracking throughout the flight, especially when executing radii. The trimming process continues. Following the 11/19 flying session, I decided to recheck wing incidence and CG. Using the Sky RC Gauge, I reset the balance point to the midpoint of the suggested CG range (160mm-220mm), measured from the wing's trailing edge. I'm also considering changing out the PCK 4-bld drive for a PAP Precision Low KV 2-bld drive.Angel's Shadow Bipe V20
This was the 2nd outing for the V20. Flying a biplane is going to take some getting used to. First, the positives. It's very stable but responsive. Rolls and pitch feel are good. No real coupling is detectable with rudder. The size of the silhouette, combined with the color scheme, makes it very visible.
Adjustments and or change.
- Very draggy, with the reduction of power, there's a rapid loss of airspeed.
- Much slower snap-roll rate compared to mono designs.
- Excessive braking with the current power system. Will change from 22x13 to a 21.5x13 next outing, plus some throttle curve fine-tuning.
- Considering swapping out the Hacker C54 for a Contra system
