Model Forum / Radio Controlled / Helicopters / December 2006Need more room!
It's been windy here in South Florida, so I had to take the car, motorcycles and bicycles out of my 2 car garage. I can slide the CP around at 1 foot above the floor, and if it gets too close to something I just set it down. It reminds me of an air hockey puck, give it a little tap and away it goes! I hope this is ground affect 'cause it's pretty tricky to try to tame down. <whew> After one battery I was totally exhausted. Another day with no damage though! Question: My manual is written for experienced pilots and doesn't label the TX. What does the "TRAINER" switch do? ..and it says zero about maintenance, do you lubricate the main gear and tail rotor gear? ..with the size of my main gear, that little motor must hit some serious rpm! ....jerry >It's been windy here in South Florida, so I had to take the car, >motorcycles and bicycles out of my 2 car garage.

Remember to input the corrective stick movement and then JUST as the heli starts to correct, remove that corrective input or it'll just go the other way and you'll end up getting behind the helicopter. Also remember you're moving a lot of air in an enclosed space. Eventually it'll get squirrely because of the turbulence you're creating. Opening the garage door might help some of that turbulent air "spill" out - but then you may have wind stirring it up even more. >After one battery I was totally exhausted.

The trainer switch is used to take control of another transmitter via a cable interface between two of them. Say I was teaching you to fly and we're "buddy boxing" (That's what we call it when we've each got a Tx and we're tied together with the cable) You start to lose control so I'd flip the trainer switch and take control via my transmitter. Once it was stable, I'll release the trainer switch and you'd have control. >..and it says zero about maintenance, do you lubricate the main gear >and tail rotor gear? I use silicone spray lube or Tri-Flo oil and lube all the moving parts except the servos (they're internally lubed) and then wipe off any excess. >..with the size of my main gear, that little motor must hit some >serious rpm! My brushless goes 3600 RPM per volt and I use 11.1v LiPos. That's almot 40,000 RPM at 100% efficiency. It actual practice it's more like 34,000 RPM unloaded. I think the main gear is 140 teeth and I run an 8 tooth pinion which nets me a headspeed of about 2100 RPM. Take it up to 3 feet in my tiny garage, I just bought it Tuesday. As George Bush Sr. would say..... Thought about it! Maybe could have done it! Not gunna do it! ....LOL ..maybe next week, I'm still waxing and detailing it! <sigh> jerry > Take it up to 3 feet in my tiny garage, I just bought it Tuesday. > As George Bush Sr. would say.....

Give it a week or so though till you get used to keeping it from drifting side/side and get that tail to stick. On a side note. Somewhere or another I heard about a guys site, Radd school of something heli. I glanced at it and it looks like good info. You might want to track it down as it seems his step by step runs through all you'll ever need. Yep, Raad's School of Rotory Flight. I did all the lessons. jerry |
