Hi.

I have a question. I like the sound that produce my Zinger prop. I know that prop its so bad. I will change the prop.

I know many people here some times are worry about the sound because is an issue in somes club with sound restrictions.
Thanks to god in my club i have no problem and we dont need canisters.

Witch prop have a nice sound without sacrifice the power?

I have 2 airplanes. AW 35% with a DA-100 and a GP PW Extra 25% with a DL-50.

Try the Vess props I have had really good luck with them. My DA-50 w a KS1060 pipe is running the Vess 23B at 7200rpm. Personally that is the only prop I use.

Uhm your don't say what size prop your using ....an 8" x 6 pitch can be some what loud on a DA100 ....LOL J/k
Have you tacked your prop? you might be able to go higher in pitch / dia or you can try a 3 blades they're a lot easier on the ears if your maxed out on a two

Nelvick · 10-02-2008, 10:20 AM

Actually i have a 22B prop ready to use. The only reason for dont use the prop yet was the screws are to shorts using the Tru-turn spinner. i have get new screws for test that prop.

And what about Carbon props? for my DA-100? I have a PT Model 27 X 10 prop righ now and it does not make noise.

ultrasportpilot · 10-02-2008, 10:22 AM

I recieved your PM Nelvick but it won't let me send you one back to you.

Nelvick · 10-02-2008, 10:25 AM

Let me check my PM options.

ultrasportpilot · 10-02-2008, 10:25 AM

Cool.

Nelvick · 10-02-2008, 10:29 AM

Ok. solved.

Why people dont use 3 blades for 3D? i am a newbbie in Giant scale yet.

ultrasportpilot · 10-02-2008, 10:32 AM

I only use 3 blades for IMAC. The two blade prop allows the engine to spool up quicker and hold a higher rpm.

ultrasportpilot · 10-02-2008, 10:32 AM

On my DA 50 I flew a 20 x 12 3-blade for IMAC.

Blip · 10-02-2008, 10:41 AM

Yea 3's ok for IMAC but with 3D its nice to know you have that extra speed on pick up if you get into the smelly stuff

ultrasportpilot · 10-02-2008, 10:42 AM

True

Nelvick · 10-02-2008, 10:48 AM

Ok. Now i understand. Is for the torque.

Blip · 10-02-2008, 10:53 AM

Actually nope its not FOR the torque. a 3 blade produces more torque than a 2 blade but the engine can turn a 2 blade faster cuz it produces less torque.
Its about prop torque versus engine torque.

Nelvick · 10-02-2008, 10:58 AM

Low pitch = More RPM in less time. High Pitch = More torque but more time to get rpm?

3 blades = More pitch in comparation with 2 blades?

I know all depend the combination of engine and prop size too.
