Angel's Shadow V20 Bipe Update
In early 2022, I took delivery of the ASB bipe, just before the Ukraine/Russia war broke out. It was made ready to fly soon after delivery with the same equipment configuration used in my BJ mono planes I was flying. i.e., Futaba servos/receiver, Hacker C54, D3 controller, etc. The plane sat until its maiden early fall 2025. The initial flights went well. The C54 performed well, but I felt it was time to upgrade the power system by trying something different. I considered PAP's PCK 4 bld, but it would be challenging to fabricate a mount to accommodate the nose configuration. I emailed Vladimir in Russia, the designer of the ASB, about retrofitting the ASB with a Dualsky 3500 contra. Asking if he could make a nose ring to properly mount that motor. To my surprise, he replied yes.
The DS 3500 was purchased from Rombaut RC and installed. For peace of mind, the radio system was upgraded to a 2 receiver configuration on Futaba's Fasst Multi protocol using PowerBox's PBR-12x. I started using this in two other F3A models with great success to guard against frame loss and potential signal fades in congested ambient areas. The re-maiden of the ASB/Dualsky combo went very well. After 20 or so flights and several radio parameter flight control changes, the ASB feels locked. There is a learning curve in understanding throttle management with the Contra, along with biplane rudder input. Even though this is my first true Contra setup after a few flights this week, I see the benefits of both a bipe and contra power. The wait was worth it...Looking forward to logging more P-27 practice after the 4th holiday.

PCK Update - Precision Aero Products F3A Contra Killer
Originally, the PCK drive was installed in the BJ Craft Strato, which first flew in July of 2025. After 71 flights and numerous setup changes, I struggled to achieve flight characteristics to my liking. During the fall of 2025, I acquired a PAP F3A single-prop 2-bld low-KV drive from a buddy and decided to try it in the Strato. The motor swap made an instant improvement. I can only assume the PCK was not a good match for the Strato.
Fast forward to May 2026. I decided to try the PCK again in my contest-proven Hacker C54-powered Anthem. After minor surgery to the nose ring and rear supports, the F3A drive was installed. After only a few trim flights and tweaks to the throttle curve and rudder trim, I was able to fly the P-27 sequence very respectably. Because the PCK is very quiet compared to the Hacker, I was tending to overspeed, causing the Anthem to seem unsettled in horizontal and vertical uplines. The PCK 4-bld is even quieter than the 2-bld F3A drive. RC pilots rely on visual ground speed vs knowing actual airspeed. Adjusting to the lack of sound and focusing on a lower ground speed made the plane lock and return to the flight traits I was accustomed to with the Anthem. Overall, the PCK is a good power system match for the Anthem.
I’ve proven to myself that single-prop systems continue to be competitive in AMA Masters, to the ever-so-popular Contra power drives. I’ll continue to learn and improve utilization of the PAP F3A and PCK drive drives in the Strato and Anthem. Will post performance reviews on the PAP F3A and PCK drives soon.
Time to move on to the next projects involving Contra Drives mounted and ready to go in an Angel's Shadow V20 and Aurora biplanes.

Smallmouth Fishing Trip
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.
Day two…Monday’s fishing adventure with our guide Jay. The day started slowly due to cool water temps, but improved as the day progressed. Here are pics of the two nice size smallies I caught…with warmer water temps tomorrow, the fishing should pick up…
Day three…2nd day of fishing for smallies on the Janiata River. Fishing started slowly but improved as the air and water temperatures warmed. Had a first, hooking two smallies on the same lure at the same time. The scenery here is breathtaking. Had an amazing time fishing with my brother. Now it’s on to the third part of our journey to South Carolina to attend the Joe Nall RC event at the Triple Tree Aerodome.

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 Update
The Strato was originally equipped with the PAP (Precision Aero Products) PCK 4bld drive. After logging 71 flights with the PCK drive and making many configuration changes. I continued to be unsatisfied with the Strato's flight behavior. A few months back, I did some horse trading with a buddy for a PAP 2bld drive, so I decided to install the 2bld drive. Right away, the flight behavior was more to my liking. The Strato was more locked, especially when executing radii. Rudder was less sensitive. After tweaking the throttle curve, constant speed control was easier to manage.
Strato Equipment List:
- 32MZ
- 7108rx (2) using PBR-12x, Mode = FASST Multi
- HPS-704 aileron
- BLS173SV elevator

- S.BUS
