This data is I believe all quite accurate. Tim, when is HpH going to release to the public their performance figures from actual testing of the jet? It seems odd that the only figures available come from the Hollister web site.

By now, HpH should have a very good idea of fuel consumption, climb rate, speed, and range. Yet I sure don't see this information anywhere on their site. The 304S isn't just another new version of an existing glider design with a model aircraft Jet attached. the engine used for the 304S is totally unlike the tiny jets used on other gliders it is computerized also so extension, starting and running are all done by one switch, shut-down and retraction are essentially the same. The complete extension, start up takes only a few seconds....and doesn't require priming, diving ect like the current sustainer systems, shut down is the same. Reasons being obvious, glider pilots may fly a motorized sailplane without having an airplane rating and even few airplane rated pilots are Jet trained....jest are quite simple in design, but are not operated as simply as your lawn mower and handing a Jet over to the would-be F-18 sailplane pilot without such controls could create some problems of it's own...even many recip sustainers have little or no controls the pilot can actually change. http://www.wingsandwheels.com/Hph%20new.htm tim |

I can't say when they will do any web updates.....sorry..they are naturally
more concerned and involved with production than web publishing but I'm sure this data will be published soon....the data from Hollister was from data given to them by HpH. The only delivered gliders so far have been pure gliders but all are built to accept any of the available engine options I have the latest published data on my website when I get it.... tim -- Please visit the Wings & Wheels website at www.wingsandwheels.com "Greg Arnold" wrote in message ...
