Heli-Log 3:3:13b

Posted 03-03-2013 at 08:51 PM by rcnut

Today was a great day to go flying...considering it was 31 degrees with snow on the ground! The sun was out in full force...meaning not much cloud action. As long as Bob and I were standing in the sun light, and not the shade, it was rather nice...bearable.

First flight I decided to try out my Compass 3D+. It took a couple of minutes to get the motor to run in the cold, it is extremely cold blooded. However, I managed to get warmed up enough to obtain rpm on the rotor head. My 3D+ lifted off the ground as if it was summer time. Went into idle up 1 and let it rip up the sky, boy was that ever fun!

Its been a long time getting out to fly, my skills were a bit rusty, but after a few minutes, everything started coming back. Bob and I decided to take a break and warm up a bit before trying out the Whiplash. I filled the tank before Bob arrived, so everything was ready. I turned on the radio, then the heli, primed the bulb on the carb, and proceeded to start the motor with my electric starter I use for my nitro helis.

However, my starter wouldn't even turn the motor over...Hhmm. Ok, I'll use the pull start. I could feel the motor was somewhat hard to turn over due to no fuel in the motor...yet. As the fuel entered, I could feel the pull starter getting easier to pull. So I decided to use the electric starter, but it still wouldn't turn it over. Ok...no problem, I'll just start my heli with the pull start!

1...2...3...4 pulls, then it started! The motor idled nicely and was ready to go, unlike most nitro motors. Throttled up slowly and as the head speed started spooling up, the tail servo was reversed...oh! I thought I checked everything, missed that! No problem, throttled down and reversed the rudder servo in the radio. This time my Whiplash was ready for its maiden flight. I advanced the throttle and it lifted off the ground! Nice and smooth, no trim was needed.

The tail seemed to be a bit twitchy, so I lowered the gyro gain, but only to realize it was from the motor. During the break-in process, the instructions call for the motor to be rich. So that is causing the tail twitching. It will go away as it is breaking in, or in several more tanks of fuel.

I turned the heli to the right and pushed the cyclic stick forward and away it went. Nice and smooth, nothing too fast or too much collective. I flew my Whiplash several times around the field, then brought it in for a landing. Two minutes out flying around, and then one minute sitting on the ground idling. Did this routine a couple of times, then checked my fuel tank, just enough for a couple of minutes more.

Well I should of stayed on the ground, right at the 2 minute mark and right in the middle of a turn, the motor decided it was out of gas! The motor stop very suddenly, so I finished the turn quickly and started an auto. I was out a ways over the snow, and didn't want to land in it! So I "milked" the auto for about 70 feet at half the needed head speed...I would have to guess I'm around 1500 rpm's! Not quite enough, and I was right. I came in for a medium bounce and a roll over with a small slide to a stop!

Broke two servo horns, slightly bent one of the blade linkages, scratched my new muffler and canopy, and scratched some of the landing gear. All and all, it was a good flight. I can't wait to get back out and try it again! Bob said the weather for next weekend is forecasted for the 40's & 50's!!! Oh yea, I'll be ready!

More to come...
