How strong is a Whisper?

Had a call from a Whisper owner today relaying a recent experience he had in his 16m Whisper motor glider..I am very relieved (so is he!) that we elected to design to the rather tough CS22 glider regulations rather than one of the new "lightweight" categories...

Apparently got mixed up in some thunder clouds and experienced VERY violent turbulence;
1) wingtips flexing by estimated 1.5m
2) battery wrenched out of mounting
3) virtually all oil thrown from engine
4) taken to 10500' with engine at idle
5) thrown inverted at times
6) cuts and bruises from shoulder straps caused by extreme turbulence

Naturally the aircraft is undergoing a major inspection after such an occurrence.

Extremely relieved that he is ok.

Very happy to hear this :D

Whispers are strong! I realised while building and going through the plans for the build that there is lots or redundancy as far as strength goes, but then you never know when you may need it ;)

Glad that all is OK and would love to hear how the a/c is holding up..?

Pieter, how is NZ?
Have you met up with any of the Whisper owners there yet?
Missing your build posts this side!

Hi Russell,

We are loving NZ, the only negative is that it is a very expensive country, seriously! Building anything here is really expensive I found as most things seems to be imported, or at least the prices seem to reflect this! Wood, washers, nuts, bolts absolutely everything is 10x that of SA. Mild angel iron, 30x30x5mm at R90 p/m excl shipping of R160 and a 6mm washer, the very plain hardware one is R3.40 for one!

That said, the country and the people are great! Not too many builders here, or at least in the Wellington region where I am. The best news is that I'm back building and really look forward to the December break to get a lot of work done. This weekend I aim to have my whisper on it's wheels ;)

Also started updating my build log on the forum again, so the progress should keep trickling in :D
