My new "77"

[Claudio Chacon]

Claudio, how do you remove the tank?

By removing the engine first, Milton.
To me, this is a very small price to pay in order to have a rock-solid nose.

That is not unusual. Noel Drindak,engineer and stunt flyer, long advocated the concept of "closing the box". You can see his work on his build of a Steve Buso stunter. I have video of the plane.

The 72 has a definite "pulse". You control it however you see fit.

Beautiful bird Claudio.. 
What about the flight reports ?

Looking over your setup, you listed lap times at 5.1~5.2,  I like to fly a little slower something like 5.3~5.4. 
With all the reserve power of that "Big Block" you have in the 77,  dont you think it would be easy to set it up to fly a little slower. 
If I ever build something for a 4-stroke I plan to use a Saito 62,  which I feel has plenty enough power for a plane in the low 60's.

Thanks, Allan.
I could only make two flights so far (the weather here has been just UGLY for the last one and a half weeks).
The first one, with no other purpose but to get rid of the MFPMS ("Maiden Flight Panic Mode Syndrome", which I think almost every stunt pilot suffers from ) and the second one just to check CG and any evident unwanted tendencies, so, no pattern...only a few round loops. Despite the CG was just a bit aft (got to remove some tail weight I added in the bench trimming process) the plane flys on rails (very good tracking with no hunting whatsoever).
It was a promising debut.

Yes, with the carb mod that Bob Reeves recommends, you can make any RPM's adjustments at will, but 5.1 to 5.2 are the lap times I feel comfortable with to fly in any wind condition, specially in a windy day.

Regards,
Claudio.

You dont get scared on a 1st flight..

Its like going on a first date with a beautiful woman....

You show all your friends how pretty she is..
You spend all day thinking about her..
You look forward to it..
You hope it goes well...
You would like it if she did stunts 1st
Do you risk taking it inverted??
Will my friends be there to see ?


You imagine and hope for all the good things - the last thing on your mind is..

What if she ... dies on the first date...

Agree, you don't get "scared"...it's just sheer panic

Good analogy PJ, never thought about it in that way
And now that you mentioned it...you know...the fear goes completely away after that first......"FLIGHT"

Gents,

     I don't know about you guys, but I would never take a beautiful woman inverted
on the first date!

     Best regards,

Great to hear the plane is going along good.   I remember reading an article by the one and only Windy on first flights on new planes.   His first comments were on getting the engine run right.   Also about how the plane was on the end of the lines.   Then it was on to loops and inverted, also checking  on the attitude of the plane on the end of the lines.  I beleive he stated on this particular plane there were about a dozen flights before the first full pattern was done.   

I have only had maybe one or two planes that I attempted a full pattern on third or more flights.   

[Bill Little]

The latest I wait to do a pattern is usually the second flight.  Most of the time it is the first flight.
