Under 50 OZ !!!!! Thanks Randy!

[Paul Taylor]

I Just bolted on a tounge muffler from Randy Smith onto my pig of a Twister. I am now at 49.6 oz!!!!

What a difference 2.2 oz will make?
Have to wait for some better weather.

remember that lose of weight will affect your trim - so it may be a little more "touchy" than you are used to

Noted.
Thanks Wynn.

Since the Twistang is kinda porky, you should think about working with the control ratio to make it fly as well as it can. Heavy...more flap, less elevator. Light...less flap, more elevator. My "Twister" (aka Profile Centennial) is a bit heavy, tho I haven't actually weighed it. I've moved the pushrod to the longest hole on the elevator horn. It looks good...like it should work....but awaiting flight testing. I can change it back at the field.  Steve

   Probably negligible if it's trimmed perfectly at each weight.

If its trimmed correctly it will make a difference. After returning to stunt I got myself into this big airplane roundhouse. I can tell you this the next plane I am building will be quite different for the turds I have been flying. Lighter is better don't let anyone kid you. If both planes are in trim the lighter one will be easer to fly.

If I recall the Paul's original post correctly, the plane was really balancing way forward, so I am guessing that although it has trimmed down a bit in weight--not a bad idea for a plane like the Twister, moving the CG back where it ought to be is the bigger issue.

Good Job Paul. 

I remember weighing the "PIGSTANG" once at over 55ozs and was suprised it flew so well. 

Just remember...next time use a pine 2 x 4 on the nose instead of the heavy piece you used this time

Your good friend,

HA HA HA you should have told me I had a plank of wood on the nose. No place on the plans did it say sand it down to shape. Just rounded the edges and went flying. Next time tell me when I make a bone head mistake.
See you at the Pig Fest, and no we are not going to put the "PigStang" on the grill.

And yes this is all about getting the CG back onto the wing close to where it needs to be.

Hey Paul!

Glad to hear the Twistang's lost some weight. Now to get it and my Twister trimmed out.  I'm not surprised Zuriel didn't mention sanding the 2X4. You know he's got an onery streak a mile wide.

You are correct about the instructor getting out and the take off roll is shorter, BUT.
You also get a loooong glide half way down the runway on landing.

Paul,

I did not get a call with an engine running in the background. 
Did you get a chance to give it a try?

[Paul Taylor]

No I got called into work.
Bummer...

[Zuriel Armstrong]

You have to work...during the day...all day long!!!

Aah, the joys of being retired(or is it retarded)!  The kids ask me what I am going to do on different days and I reply, "What ever I feel like doing as long as the wife does not have something planned already".  DOC Holliday

Yaaaaa Doc sometimes wives are a drag but don't tell my wife I said so.

Not if you reduce your IAS accordingly.

I must report that the control ratio change on the "Profile Centennial" (Fancherized Twister) made a lot of difference. I just moved the pushrod to the longest hole on the elevator horn. Stall on hard corners is gone. It did make the porkish model respond differently. It became difficult to make a large loop...wanted to make a small one.
So, the huddled masses decided we should change the handle spacing (narrower by about 5/8"). It worked. Some other tweeks are in order, but it's much better. I didn't get the handle setting exactly perfect, but decent. The lines might be a foot too long. Might benefit from a turn on the elevator ball link, too. I got the leadouts too far forward and had to move them back...still needs some adjusting, but it needs a scale of some sort on the tip, so I can get an accurate move. I guess I'll put a bit of masking tape on the tip and make some marks with a Sharpie.

The Hayes 4 oz tank works fairly well, but needs a height tweek still, and I need to poke out the blank spigot to fill through, leaving the top one for vent & muffler pressure. That way, I can fill it sitting on the wheels, instead of standing on the spinner. It's not Uniflow, it's not fancy, but it works ok. Sure is ugly, with all the wire ties. The Magnum XLS .36 is a sweet engine, but it takes a whole lot of choking and muffler plugging to get it wet enough to get a bump or start. The TT Cyclone 11x4.5 has remained. I intend to try trimming one a little bit for this model, and I'm not opposed to trying some 11-4's, 10.5 x 4.5's, etc.  Steve

Rootbeard...I weighed the Profile Centennial, and it's 45.5 oz. The flaps move just a little bit more than the elevators by eye, and it's made a lot of difference. It's going to Clovis...  Steve
