Sahil,
I have used Cox .049 Black widow since 1991 . Used to fly it on control lines and loved the engine.
Even now i have one of them, though not installed on any airplane. Yes they do make a lot of noise, but, as Anwar said, thats the charm of it ! .
RPM is very high, power OK ( they do like a little nitro in the fuel ) .
Run it rich, and it will outlive most of your other engines.

yes that's one of the reason i got the engine but i was not expecting such high sound !

now i'm using 5% nitro fuel and wanted to know at how many turn will i be or should be getting peak RPM  ???

The "yelling" and accompanied terror will reduce dramatically when the engine is run outdoors !

YES , these COX surestarts are so small that one is tempted to run them indoors.
I remember. when i got my first one, my son told me that I had been"had', because an engine so small would certainly not run.
So i zip-tied it to a yardstick- (thing to make Coro wings) and sure enough the thing roared.
Mine ran with zero nitro, but it is significantly more powerful with 20% nitro.
I fly a little C/L on twenty feet lines and a 8 ml tank lasted 6.5 min. Each turn takes about 4 seconds, and after one sortie, i couldn't fly R/C that day , I was so dizzy.
Lovely, cheap engine.
One of the hobby shops here should buy a stock and retail them., it works great on small coro planes.
I am thinking of fitting one on a R/C plane . Fly it with  7-10 mins of fuel and then land on a dead stick.
These engines require 20% CASTOR OIL as lube. Don't use synthetic.
After the original glow head burnt, i drilled out the head, and JB Welded a OS8 plug. (i am trying to get a 1/4-32 tap from Tower). Still works great.

Hey have you tried Sharma Model's disel Engines. No glow plug and no mufflar too. They have same sound and I must say no one can beat those engines in durability. Very reliable and very long life engines, only draback is that they throw lot of exhaust (as no mufflar) go directly on the model.

Hey, can you tell me more about sharma diesel engines. I have been to website, but there are few details. Seems you have used them. Whats your opinion, since i m confused with ASP .52  and  2.3 cc sharma diesel for my first model. please help..
I can take off and fly well. Its landing which sucks :banghead::banghead:

asinghatiya

Sharma Engines are synonym to Quality and durability. I used their engine in my first model. Their engines are very low maintenance and high performance but these engines have no muffler (silencer).  You can talk to Vivek Shrma directly on this. He is very cooperative and humble guy. Number PMd.

A Sharma diesel comes in 1.5, 2.5 and 3.2 cc.
The ASP mentioned is a 0.52 cubic inch or 8cc engine.
these engines are not interchangable.
if you have a 40 or 46 size model go for the ASP .
if it is a small model think of the sharma.
but remember a diesel engine- even a sharma reqiures more expertise to run. since it is your first model go for the glow.
