Os 40 Fsr Subscribed 102 9.1k views 9 years ago here is the very first run of this classic os engine please check out my blog page more. Review of the os 40 fsr stunt by henry nelson.
Os 40 Fsr Here i use two of my personal nib (new in box) engines to demostrate the following: how to setup the engine for the first run, break in, and final tuning of the engine. Run it stock, ream the muffler outlet with a fox prop reamer as big as it goes without removing the stinger, try about a .275 venturi with an st needle. run a typical 40 45 sized tuned pipe propellor (12 4, 11.5 4 3 blade, etc), start at about 10,000 ground revs. Back in the fsr era there were only two types of engine you could get, ringed or cast iron. everyone knew that for either of them you just ran them slobbering rich at first and the only danger was a needle that wasn't open enough. The first rc engine i had was an os 40 fsr, this was fitted to my first rc aircraft which was a veron super robot. this would have been in the mid 1970's. getting sentimental in my old age i decided that i would like one of these engines again. in fact i have managed to get hold of two in qui.

Install a top quality propeller of the diameter and pitch specified for the engine and aircraft. locate the propeller on the shaft so that the curved face of the blades faces forward i.e. in the direction of flight. firmly tighten the propeller nut, using the correct size wrench. The rossi 40 45 is the best 40 45 that os ever made the 40 45 fsr was an icon in the day !. In this article, i describe how "run in" should be carried out, and how to tell if the fuel mixture needs adjustment. in order to run efficiently, model engines require a constant flow of fuel. if the flow is restricted or the fuel is contaminated in any way, not only could your engine loose power, it could cause irreparable damage.
