Half A Talk
For years, we have been making our 049 in our own way, which features ABC, 2 Ball Bearing,
Sand Case, head-off plug, which you can see from Various 049 Engines in Model Aviation Magazine.
Yes, it is a real screamer. Most engine will turn above 30,000rpm on Tornado 5x3 or APC 6x2 propeller,
and you can even run around 38,000rpm or more on our 4.5x2.5 single blade with our adjustable tune pipe.

Thanks to Mr. Glen Lee (CL speed on Model Aviation May, 1998) , Mr. Doug Galbreath (Rework on CS 049-061),
Mr.David Hull (Model Aviation April 1999) , and all our 049 friends, who gave us much advices and ideas.
We are also very grateful for our 049 runners, who have build up a sound name for us in the National Contest,
like: Bill Hughes, James Rhoades, David Hull and many.

At present, we are working our design on new Half A Pro version, and hopefully we will have it on market soon:
1) Investment mold. ( We recently quited idea about the die cast since it might be too weak for this performance.)
2) A slightly bigger capacity upto 0503. ( longer stroke )
3) Nielsen style plug
4) A CNC process tolerance control on production
5) A compatible mounting size as COX.
