Nice shots of the Stang Dick

Do you have any video?

I would also like to ask you about the Saito running inverted, are you using a pump or any on board glow system for the engine.

Thanks.

Reincarnate,

I would not recommend trying to fly the plane with a 6-pitch prop turning less than 8500 RPM. Been there done that with the 77" version and 200Ti and it was a very scary flight. You will need to generate some speed for the plane to fly good and you will find that this is just as important as static thrust.

I recommend that you drop back in diameter so that you can turn at least an 8-pitch prop. After managing to save the plane with the 18x6 I tried a 17x8 next. Much, much better. Then I went to a 16x10 which was better yet. All of this was with the 200Ti turning well under 9000 RPM.

Walt

Walt, thanks for helping. The 18x6 I'm running is for break-in process, and the spare Zinger Pro was an epic mistake (ordered wrong size

) I however wasn't exactly sure what to fly with, so your help was greatly appreciated. Checked the specs on both your engine and mine, and aside your's being larger cc, and heavier, and way cooler looking, they scope out real similar, from prop to rpm. Do you have any idea on the hp rating of the 200Ti? Again thanks for you valuable input.

Ian...
Regarding the 6 Volt system the JR 791 will not function past approx 5.4 volts.

Sorry can't figure out how to quote a portion of a post. That being said, the above is your reply on the 791's. I've got them hooked up to my 6v system, (still. Haven't decided what to do) just checked my battery (hobbico voltmeter) with Rx load on and read 6.52 volt. The servo's work fine, and have probably cycled them approx 50 times testing, adjusting and just watching them work. I'm getting no buzz, hum, chatter or anything from the servo. I swear I'm not being argumentative, just trying to deal with this issue. If my questions are helping someone else, then it will worth the trouble. I just can't believe I'm the only person with 791's on a 6v system.

Hopefully you guys don't think I'm an idiot or a fool. The constantly learning process I go through just makes it seem that way. Bear with me please. And if you believe me, please inform my wife. She thinks I'm an idiot, a fool, and a few things the moderator would edit.

OK I give. Sank another $54 into mine for a 4.8v 4500mAh battery, and put the 6v into the "gotta be a use for this someday" box. Great diagram provided by Bo, just didn't want another battery's weight or cutting another hole in the side for charge jack. Bright side is that I just shaved off another few oz from the frame. My God I hate to give up, but it was a good fight.

What I wouldn't give to live south of the Mason Dixon with Pettit. It even looked warm in his pics! Glad to see one in the air.

Been thinking about this too. Is there some reason why a voltage regulator could not be used for the retract servos?

Answers to some questions.

Yes, I use a McDaniel onboard glow lighter connected to a separate channel so I can turn it on or off anytime.

Omega 15% 2 stroke fuel, hence the "vapor trail"

Sorry, didn't do any video this time.

Reincarnate,

I don't put much stock in horsepower numbers, but the 200Ti makes power somewhere between a 150 and 180 Saito. I liked a 17x8 APC or 16x10 MA Classic best with the Mustang. I since moved the Saito to a Dynaflite Decathalon and fly it with a 16x8 APC.

Look what finally got here! My Evolution 35GT with Evo wrap-around muffler. Man, this motor is one nice bit of machinery, from the looks of it. As soon as I'm finished with my current project (wings in background), I'll crack open the Mustang kit. Gettin' all goosey for this one!
