Title: Double Star 40
Post by: Sam Laughery on March 24, 2008, 02:57:25 PM
I just bought a Double Star 40 from a good friend while visiting Pa this past weekend.  I was wondering what are some of the options for a muffler.  I'd prefer a tongue muffler.  I think the break in procedures are the same as for the B40 and I know I saw them posted somewhere but can't remember where.  Can someone help me out?

Hi Sam, You'll be happy to learn that any muffler which you may have for a Fox .35 will fit the DS .40! Which means that any FP .35/.40/LA Mufflers which you've got will also work! Amazing! I truly enjoyed my DS .40 which powered the late lamented Veco Smoothie which I used to fly in Classic! It did have an ST NVA installed and sang a great tune with an APC 9.5 X 4.5 prop! Fuel was 10 11-11 and on cooler days 7.5 11-11.

Tom Dixon in Marrietta Georgia is the main man for Double Star engines. He keeps parts and is super knowledgeable about these motors. He flys them on his own ships too. He has a website.

From Tom, himself:  Add a couple head shims since the engine is set up for FAI (no nitro) fuel out of the box.

I have found a new NVA (PA) and a new venturi, around .295, and a total of 3 shims really brings the DS 40 (plain bearing) to life on 10% nitro in the summer..
