Hint of the Week: I've had issues with an F-5 Tiger II recently. I know it'll be fast. Skyler's is a sight to see!
Maidened it about a month ago. Tail-heavy. Crashed. My fault for trusting an unreliable internet source.
New Fuselage. Everything as good or better than new. Second take-off proved very unstable in Nose Gear Steering. As soon as it picked up speed, the smallest correction made it swerve off the side of the Runway. I was already very mellow in rates. I had softened the Main Gear Springs as they were very strong. Thought maybe they were an issue. Wasn't on 1st flight! Had minor tip damage, so back to the shop and try the next day.
Tightened the springs back up. Re-adjusted Rates and Expo on NGS. Same exact dance on the roll. Never took off. Tip Missile Rail damage. Took it home for another fix. This time went the other way with expo (reduced).
Next day, again, the same thing! OK!? Of all things, it did not exhibit this behavior on the very 1st flight. STOP. I had a couple Assan Steering Gyros left over from other projects. Great little units. They totally tame this sort of thing. Installed. Tested out on the front road. Everything good. Locked in! Yay!!
So, today I went out. Plugged her in. Lights, but no movement. Re-bound her. Great... movement. Pulled the Bind plug. Everything off. Back on. Lights, no movement. Damn! I did have a thought of flying her after I bound her, but That quickly faded from my mind. Back home we went.
Different Rx... Lights. Movement! Assan Gyro working its magic, too! Range Check. All good.
So. I had plenty of chances to force her into the air. Even extra T.O. attempts, I did not do, because I knew there was an underlying issue. Finally, I got her running straight with the gyro. Then, I found one more issue... the receiver. I had a chance to fly her then, but I didn't. Why? Because, operating with a receiver that is now suspect is asking for trouble. Not to mention, dangerous.
And, the hint... Guys, don't risk your aircraft. You paid good money and spent gobs of time on it. More importantly, don't risk other folks' safety. That's the most important thing. Keep you, you friends, park patrons, safe, always. Don't let the inner urge of flight push you into failure. Nothing is that urgent. If there is an issue, no matter how many times you take a plane back home to fix... DO THAT!
I wish all of you many safe, many fun hours of flight every day.
