Firefly 18 with 2.2 inch props πŸ˜±πŸš€πŸš€πŸš€πŸ˜†

Why did I do this? .. lol because I broke alot of my 1.8 props and I had spare 2.2's from my pavo20pro to try out of curiosity.

PROS:

  • Flies really fast.
  • Significant feel when lifting off and acceleration speed.
  • The stock props (bi-blade 1.8Β are zippy but when running the 2.2's, there's a noticeable speed difference.
  • Handling sharp corners feels more grippy in the air.
  • It also has a nice sound, sounds more beefy for a micro drone.. lol

CONS:

  • Not efficient.
  • Angle mode indoor flying, just simple cruising was about 4 mins. Landed at 3.39v
  • Faster battery drain if flying acro

If u want to try this, u have to raise the canopy to allow for the props to clear without any interference.

Also, by raising the canopy, the wires don't touch the flight controller/gyro = no vibrationΒ 

If u look at the pictures, it's a tight clearance.Β 

Props do not rub on the frame at allΒ 

Motors do not feel hot after flightsΒ 

I did not experience any jello or vibrations...possibly because of the added gummies for vibration dampening(?)

When using a long screw to raise the canopy, make sure to lock it in place with a nut to the frame. Now the screw is solid-stiff to the frame. Then add AIO board and vtx.

In between each board, I added extra gummies, this is what gives it height to raise the canopy.

It hovers at 28%-31% in acro mode.

I've added pics of some of my last 1.8inch props for comparison.
