Default First flight...

Wouldn't be one without interference right? Started with a quick, short dip down, then another. Instructor knew it was time to land after these repeated hits. but there just had to be one more. 2 feet off the ground as he was coming in, it punched the throttle and went straight down luckily my midwest didn't take it so bad, only body damage was sheared nylon bolts for the gear and on the wing, well you can see. It was one big wing, split finely in 2 and the left wing has some damage. there is a rectangular peg type thing that helped hold the wings together that I am drilling out and replacing its about 1/2" x 1/8" how deep do you think it needs to be? I now I have it 2 1/4" it each wing (the mength of my bit).



Only my second flight too. I hope to fly by next weekend.

I'd be more concerned about the radio interference. It's not very common when using a dual conversion receiver with proper antenna routing and a radio system that is in good running order.

If proper frequency control is used at your field to prevent simultaneous transmission, and you're sure you weren't being "hit" by another pilot, you probably ought to give your whole radio system a good, thorough once-over:

-cycle transmitter and receiver batteries to make certain they are delivering rated current capacity (Mah)
-range check transmitter and receiver thoroughly
-inspect receiver antenna for damage, make sure it's routed away from control rods and servo wiring
-inspect servos and control rods to assure there is no metal-to-metal contact points to cause RF noise

For as much hoopla as the new 2.4Ghz radio systems are getting, the truth of the matter is that 72Mhz radio systems today are really, really reliable as long as they're installed and maintained correctly and clubs follow simple frequency control measures to prevent channel conflicts.

If your plane was taking "radio hits" and nobody was on another transmitter with the same channel, something is wrong and needs to be sorted out before you fly again.

Don't forget to make sure the antenna is not looped back on itself, anywhere. Also, range check the radio with the engine running as well. Many interference issues only crop up when the engine is running at different speeds. Just make sure you have somebody holding the airplane just in case the engine goes WOT on you. Check the crystals on the transmitter and receiver for proper seating. A loose transmitter antenna is also a fairly widespread issue with new equipment.

Luckily the damage to your model is quite mild. At our club we had a midair collision which totaled two trainers last week. One of the instructors came out of a loop surprising the other and BOOM!! The engines were never found.

Sry for the loss. I guess it could have been worse. I was flying yesterday and 4 people crashed. One was easily repairable, one could be repaired or replaced, and two were destroyed.

When you say it was your second flight, do you mean for that plane, or like ever. If thats was your second flight ever, then dont be discouraged. There is a man at my field that has been on a buddy box for 4 years. He has destroyed at least 3 planes. And yes, one of the two that were destroyed yesterday was his. If front of our runways (a good distance in front) there is a hill that comes down and back up, then some flat land, then our runway. Well where the land comes back up, his slammed the plane into that slope while turning, trying to land.

Definetly check out your radio, before next flight.

Yeah, the guys at my field blame my cheap looking chinese micro reciever so they are giving me one form the old club trainer. I tell you what joining a club was the best decision I ever made, these guys are so nice and generous. They gave me everythingI needed to get up: a battery, starter, and sold me a plug n' play trainer for $75.
