Good Sport F5D set up.....(Again Sport flying only !)

[MikeRC]

Hello everyone,
I’m looking for a solid, tried-and-tested light sport flying setup for the Jolt 2. I’m not entirely sure if this is the right place to ask—so if this topic isn’t appropriate for the forum, please feel free to remove it.

That said, I’m aiming for a reliable weekend flyer—something quick but manageable for casual sport flying. The setup I’m currently considering is based on a few YouTube videos that really caught my attention, especially in terms of performance. However, the gear featured is from 8–9 years ago, so I’m wondering if there might be more modern alternatives worth exploring.

Here’s the setup I'm considering:

• Motor: Neu 1115/1Y (2800KV)
• Prop: APC 4.75x5.5 – (Still unsure if this is ideal)
• ESC: Castle Edge Lite 130A
• Battery: 5S 2700mAh 70C
• Servos: KST X08 – Should I go for the KST X08H version (no tabs) for wing installation?

My Jolt doesn't have flaps, so I’m a bit concerned about landings and want to keep the setup as light as possible.
A few questions I’d appreciate input on:

• Will this setup easily reach 200+ mph?
• Is the prop too small for a reliable launch?
• Should I expect any torque roll on launch with this configuration?
• Are there any newer motors or components that could outperform this setup for sport use?

Looking forward to hearing your thoughts and suggestions!
Best regards,
Mike RC

@Jarron Should be able to run some numbers for you pretty soon.

That setup checks out on eCalc. You should make 60 oz of thrust static and about 120 oz of thrust once airborne and past 157 MPH, estimated top speed is 235 MPH, estimated watts is 1300 at 75A, meaning you don't really need that big 130A ESC. I don't really think there will be much torque/P factor, it's a small prop on a fairly large plane. You are go for launch.

Thank you for the confidence-inspiring response — much appreciated.
Just to confirm, you ran those numbers on a 5S setup, correct? I’ve noticed that many others using a similar configuration are opting for a 130A ESC, but based on the data, it seems that a 100A Castle Edge Lite would be sufficient. This would allow me to save approximately 0.8 oz and reduce cost, without compromising performance.

Would you agree with that approach?
