Title: Brodak 40 : Best Props ?
Post by: Robin_Holden on April 20, 2010, 01:46:53 AM

Greetings fellas from a sunny [ at last ! ] S.W.France.

My Brodak 40 has been carefully run-in.

It's installed in a Sig Banshee and ready to rock n'roll.

My fuel is 5% nitro , 24% lube' [ 50/50 ]. Uniflow plastic tank .

What would be your recommended prop' please ?

Oh..... It's a great engine by the way .

Much obliged for any contributions ,

Robin [ ex-pat Brit in the Charente full of ex-pat Brits ]

I have found the Master Airscrew 11X4 works great on mine in a Nobler and Smoothie both at 42 oz.

So far I am sold on the Top Flite Power Point 11-4 wood blade.  Have tried the APC 11-4 and it is heavy.  Zinger 11-4 is too thick.  Master Airscrw 11-4 wood is the nxt best prop, just need to order some more of them.  By the I use Excalibar 10% with 22% oil(1/2 & 1/2).  Also run in a rich two stroke mode.

The two best B-40 props that I have found are the APC 10.5 x 4.5 and the Thundertiger 11X4.5.  8)

My B40/NoblerARF really likes the Zinger wood 11-5 cut down to 10.5.

I've watch Pete Peterson flying his Rondenelli Venus with a Brodak 40 and the Cyclone 11x4.5 prop for awhile. Great setup.

Top Flite 11-4 works brilliantly in mine.
