I'll try to be brief - but need your feedback quickly.
We recently joined the ranks of those converted to useing LH or Pusher props. The performance difference was in our case nothing short of stupendous. THe only problem is the current SELECTION of pushers is slim. Most are 2:1 dia:pitch ratios, which are good for efficient THRUST but do not BRAKE as well as they could. We need lower pitch.
We have been in contact with APC and they are willing to introduce a new size for a 200 unit order. We are willing to commit to buy those 200, but will not use them all ourselves! YOU, dear SH friends are the likely customer base!
The size we are thinking about is a 13x4.5 Pusher:
* The diameter is somewhat larger than most folks use, but it is easy to trim down. Also there are a lot of people looking at bigger power systems.
* We have noted that a lot of the SH folks have been de-pitching their 6-pitch props to 4.5 to 5 range.
* We have recent experience with a Strega flying with a 13x4 (RH) that really works well at 11,000 RPM, but a little slower would be nice. We think the extra 1/2" pitch will let it fly around 10,300 or so...
* The expected price for the new prop is $7.50, lead time roughly 30 days from the commitment to buy.
* The props would be essentially the same as waht we have come to expect of APC-E props, just a different size.
SO THE QUESTIONS ARE:
* Are YOU interested in purchasing this size prop - and roughly (non binding) how many?
* If you have any concerns about this size, what ALTERNATIVE size would make it an easier for you to commit to buy?
