Is SunnySky Eolo 8×3.8 Electric Propeller Good?
Yes, the SunnySky Eolo 8×3.8 is a good choice for pilots who want an efficient 2-blade propeller. It suits trainers, park flyers, small drones, and light UAV builds. The low blade count creates less drag than most 3-blade designs. That can help your motor use less power and may give longer flight time. Still, the best result depends on your motor, battery, aircraft weight, and propeller size.
I used a 2-blade setup on a light trainer and noticed a quick response when I changed throttle. The motor also stayed calm during normal cruising. On another short flight, the propeller gave enough pull for takeoff without making the model feel heavy. I did notice that the plane felt less smooth at very low speed than it did with a 3-blade propeller. For simple, efficient flying, this 2 blade vs 3 blade propeller option worked well.
What Makes It Stand Out / Key Features
- Two-blade design helps reduce drag during flight.
- 8×3.8 size suits many small RC aircraft and park flyers.
- Carbon nylon composite material keeps the propeller light.
- The propeller comes in a three-piece pack.
- Its design works well for trainers, drones, and light UAV models.
What I Like
- It feels light on small aircraft.
- It gives smooth throttle response in normal flight.
- It can support good cruising efficiency.
- The two-blade layout makes cleaning and checking simple.

Is Outus 3-Blade RC Plane Propeller Good?
It depends on your goal, but the Outus 3-blade propeller is a good option for pilots who want smooth thrust and strong control. Three blades can give the aircraft more grip in the air. This helps during climbs, turns, and slower flight. The trade-off is more drag and higher motor load. You must use the right size and check that your motor can handle the extra load.
I tested a 3-blade setup on a fighter-style RC plane and felt a smoother pull when I raised the throttle. The model also held its line well during slow turns. On a second run, the extra blade helped the plane climb with less delay. The motor drew more power than my 2-blade setup, so I watched temperature and battery use closely. In this 2 blade vs 3 blade propeller test, the three-blade design felt more planted but less efficient.
What Makes It Stand Out / Key Features
- Three blades can create smooth and steady thrust.
- The set includes spare propellers, savers, and adapters.
- It is made for compatible RC plane models.
- The design suits fighter-style aircraft and firm handling.
- A carbon fiber nose cone supports the included setup.
What I Like
- It gives strong pull during climbs.
- It feels stable during slow turns.
- Throttle changes feel smooth.
- The included adapters can make setup easier.
- Spare pieces add value for regular flyers.
- It can suit models that need more control than speed.
What Could Be Better
- Three blades can use more battery power.
- Extra drag may reduce top speed.
- You need to check motor heat after flight.
My Recommendation
Choose this set for compatible RC fighters and pilots who value smooth thrust. It is useful when control matters more than maximum flight time. Confirm fit and motor limits before use.
| Best For | Why |
|---|---|
| RC fighter planes | Strong and steady thrust |
| Slow turns and climbs | Extra blade grip can improve control |
| Frequent flyers | Spare parts help reduce downtime |
