Heli-Log 4:28:2013

Saturday (yesterday), 67 degrees, 0-5 mph winds, cloudy then cleared up.

Last weekend I met Mark, a new heli pilot in training. He came out with his two heli’s, and I brought two, my Whiplash and Rave…before a motor transplant. I watched Mark fly (hover) some to get an idea of where his skill set is.

Then I pulled out my heli’s and did a little “whaling” on them. That got Mark’s full attention very quickly! He couldn’t stop smiling, that made me feel good. So we spent...

Sunday…60 something degrees, winds 25+ mph gusting to 35+!

Bob and I went over to friend’s house for a little show and tell…my Whiplash Gasser! Jerry has several gas heli’s (2 MA 1005’s, an older Hirobo, and a Vario, from what I saw). Jerry was interested in seeing my Whiplash from everything Bob had told him earlier in the month. When we showed up, the first things out of Jerry…did you bring your Whiplash and are you going to fly it?

We spent an hour looking over the...

Sunday, 62 degrees, winds 5-10 mph North to Northwest…very Sunny!!

I spent 2 hours Friday night starting the repairs to my Whiplash, then 6 hours Saturday to finish. But Saturday was crappy weather, heavily overcast with constant threats of pour down rain…and windy –> 25 mph with 35-40 mph gusts. So it was a good day to wrench on heli’s.

The rebuild was straight forward. Damage was at a minimal this time, compared to other crashes I’ve had in the past, hidden damages....

My Whiplash motor...a closer inspection

I took a look at my TRM270TT (Zenoah) motor last night. I removed the muffler and spark plug. The piston, ring, and cylinder wall looks great! No scaring, scratches, burns, etc., it looks brand new inside, well the piston and cylinder wall. The top of the piston looks great for running rich. It has a slight brown/black tint to it. It looks as if it was run, but not long.

The rest of the motor (the case) is in great shape, no cracks...

A deeper look into the damage on my Whiplash…

Starting with the head… The rotor head is fairly tough; I bent one control arm on the blade grip. The spindle/feathering shaft, dampers, blade grips, and head is fine. Mainshaft bent bad, mainshaft bearings (3) notchy, main gear trashed.

I pulled the motor expecting to find a mess inside…and I wasn’t disappointed! The pinion was glued onto the bell from the baked grease. The sprag bearing was heavily tempered, it looked...
