Taming the intolerable Ares XL

[smirkracing2024]

Hi all,

I love the new Ares XL from Twisted Hobbys.

TH 39" EPP ARES XL JET

TH / RcFactory EPP ARES XL JET

However, I hate the sound (just can't stand it). I posted a hare-brained idea in the Ares XL thread on RCG (chop the nose and move the entire motor+prop to the front) and the rep from TH pointed me to this thread as something to explore before performing any major surgery:

Prop Slot Noise Reduction Design and Tests - RC Groups

Discussion Prop Slot Noise Reduction Design and Tests Foamies (Scratchbuilt)

www.rcgroups.com

After checking it out, I thought it might be of interest to some of you here, as the noise of pushers, and worse, of prop-in-slot planes, really limits their utility. I can't fly such noisy planes at any of my local parks or flying fields because it would annoy the daylights out of everyone.

If you have insights or tips or ways of taming a prop-in-slot plane's noise, I'd love to hear them. I'm keen to make the Ares XL tolerable... because apart from the noise it seems pretty amazing.

Thanks!

Don't have time to look too much into that thread on RC Groups but guessing noise is always going to be an issue with this style plane.

Curious any improvement or does it get worse if you add additional blades? Basically a ducted fan has to deal with the same sort of issues with structures very close to the blades.

Jarron recently made a test flight with a 1 bladed ducted fan just for the funny of it. It made a good bit of noise, but flew about the same. The ducted guys have shown more blades are better for sound. The same with drones, a 4 or 5 blade on a drone is very quiet.

I've been wanting one of these but the noise is the main problem for me as well. I will be curious if improvements can be made
