As we put the final touches on our latest 1100mm PNF warbird (codenamed: Aleutian Stripe), our test pilots spent weeks in the hangar dialing in the power system. This airframe features a relatively short nose moment. While this gives it that aggressive, muscular scale look, it means battery weight and physical dimensions are critical to achieving the perfect balance without adding dead lead weight.

We tested our Turnigy 2200mAh batteries - and the 3300mAh shorty "cheater" - to see how each affects performance, handling, and that infamous propeller howl.

Here is the breakdown.

The Contenders: Physical Dimensions & Weight

Before we talk about flight performance, let’s talk about fitment. The battery bay on this 1100mm airframe is deep but relatively short to maintain structural integrity around the firewall. You will have to push the battery all the way to front to maintain the Centre of Gravity.

Flight Performance & CoG Data

We mounted each battery in the plane and pushed fully forward against the firewall. Our experience are as follows:

Our Recommended Starting Points

For your maiden flight, we recommend use 4S battery and setting your timer to 4 minutes. Starting with

Important Caveat: The Graphene 100C is the heaviest pack in our test. If you use this, you must adjust your elevator rates higher to compensate for the forward CoG during landing flair.

The "Sound" Factor

We also used a decibel meter (just for fun) to measure the prop noise. The 4S battery produced louder pitch scream. If you're chasing for "Howling" sound, any 4S packs are your clear winners.

Final Word from the Test Team

This airframe is somehow forgiving if you match the battery to your flying style. We designed the battery tray with a velcro strap that accommodates thicknesses from 24mm (Shorty) up to 32mm (Standard 4S).

We are currently finalizing the production run. The official name and exact release date of this 1100mm warbird will be announced shortly—but now you have a 1-week head start on selecting your ideal power plant.
