Propell / DL100 / Støy

[weddowickh]

Hei.

Kjører en Dl 100 motor med en tre propell på 27 X 10
Det blir en det støy fra propell.
Er det noen anbefalinger hva jeg kan bruke for å redusere støyen og beholde ytelse på motor ?

[anders e]

En mejzlik (27x10) vil alltid fungere bra.

Bruker det på min DA-100 i imac. Dyr men meget bra

Ok. takker .

Er det mindre støy i en karbon propell i forhold til en i tre ?

[william123]

Jepp, karbonpropeller lager mindre lyd. 3 blader hjelper også på lyden. En annen ting er å sette på canistere hvis du allerede ikke har det.

Var det jeg tengte meg ja .
Cannistere er montert.

Hvordan hadde det blitt å gå opp til 28x12 feks.

Blir det ikke mindre dra kraft med 3 blader da ?

[anders e]

Ja, en 3 blader drar tyngere.
Skal du prøve større ville jeg tatt 28x10, men den går også da litt tyngere.

Ville valgt en 27x10 mejzlik.

Hvis flyet ditt er greit motorisert i forhold til vekt, vil ikke en tre-blads propell være noe problem. Bruker selv en Engel 3-blader på et 20-kilos fly. Hovrer fint på ca halv gass.
Jeg er aldri i nærheten av å få noe tipp-støy fra propellen.

Siden vi er inne på emnet; Hvilken 3 blads til en Xtreme composite edge 540/DA100?

Lite sugen på å "prøve meg frem" for mye, ettersom karbonpropeller koster en del.

En kompis av meg bruker Mejzlik 25x12S på sin DA100. Det fungerer fint.
Jeg bruker en Engel Supersilence 26x12 på min 3W 106CS. Får ca 6100-6200 rpm med denne propellen. Ville aldri hatt en annen propell

Vi har testet min propell på en DA100. Den gikk litt stillere enn Mejzlik 25x12S. DA'n dro Engelen helt fint. Målte ikke turtall, men DA'n er ikke så sterk som 3W 106CS.

2-blads 27x10 er etter min mening for lite propell for en DA100 eller 3W 106! For mye støy!

[Sniper]

Takker for svar Da går det mot en 25X12S mejzlik.

[weddowickh]

Takker for alle bra svar ..

Hvor får jeg kjøpt Mejzlik og Engel propeller for en grei penge ??

Fant denne på et annet forum i utlandet ..

Vet ikke om den kan være noe til hjelp ....
