Re: [RCSE] New experiences and questions
Does it sound like I am doing anything wrong or could do them better? Our club is mostly nitro, with a growing electric presence, so there was not much sailplane guidance available (but a lot of willing help with the line) It sounds like you are doing fine, just continue to have fun! I don't know where you are in Ohio, but there are some nice soaring clubs in the state there. You should try to hook up with some of those guys, you wont believe what you can learn when you fly with other soaring enthusiasts. Thanks, Jim. I live in Wadsworth and work in Beachwood. There used to be a soaring club in Wadsworth, and I even went to one of their meetings, but that was back when I did not have much spare cash for hobbies. The hobby budget has opened up a bit since then, but I cannot find anything on the Wadsworth club.

That reminds me - I started looking for a LoLo, and I only found lomcovak. Does anyone 'locally' deal in these? Johnny? Thanks, Brent RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] New experiences and questions
Hi Vince, A few years back, I became intrigued with high-start launching and began to look at how to optimize a launch. My ruminations have been included on the Charles River Radio Controllers web site: http://www.charlesriverrc.org/articles/design/dickwilliamson_histartphysics.htm To translate between the table in CRRC article and the tubing supplied by Mark Mech and NSP, I have created the following table which I hope survives transmission via email without screwing up the formatting. Tubing sizes are listed in order of increasing cross section. CrossInsideWall CRRC Mech NSP section dia. (sq. in.) (in.) (in.) 0.024 1/16 1/16hand launch- - 0.025 1/83/64 - - upstart 0.037 1/81/16 2 meter2 meter - 0.049 3/16 1/16 - - M 0.064 1/83/32 - comp 2 meter - 0.074 5/16 1/16- - standard 0.098 1/81/8 standard3 meter - 0.101 1/43/32 - - L 0.138 1/87/16heavy duty - - High starts work nicely, especially with some head wind. However, you need a strong arm to launch a heavy plane. Regards, Dick The end of the soaring season is close here in Ohio, and the sun was out this morning. I had previously test launched my newly acquired 150 Aquila XL off of a histart made for a 2 meter (wimpy), but I thought today would be a great chance to try the bigger hi-start. Loaded up the car and drove to the club field. Range check OK. Walk WAY down the runway to stake down the end of the histart. I have only done a dozen histart launches in my life, and only 2 in front of anyone other than my dad and brother, so I am a bit nervous. I put about 60% of the stretch to try it out, point the nose at the horizon and give it a heave. WOW! I mostly let it do it's own thing, with very minor rudder corrections and just a bit of down elevator, it climbed in a nice arc. Don't know if that was right, but it felt good. Since I had not given it a full stretch, it ran out of pull before it had more that about 200 feet of altitude (guess) I did a lot of lazy circles (sun hid behind the clouds, and no thermal activity to be found with my meager skills) Landing was great, and the next launch was with full extension of the histart. Very impressive launch. I think that it was nearly over the stake before the line pulled off the hook. I played around, going upwind hunting, but there was no sign of lift, so I was back down in short order. 4 times in my RC career I have specked out my birds (Zagi wings and Dads 2 meter electric) so I can't wait to try it with this majestic sailplane! (plus it is bigger, so specking it will mean even more altitude!) Sorry for the novel, but I am stoked. I know that this is an ancient design, but I was in heaven. Now for the questions. Our fish scale said I had 25 pounds of pull at full histart extension. Is this too much? Can I try for more? Without a zoom launch at the top, a 510 foot histart, and a mild headwind, am I really about 500 feet in the air? (I am trying to come up with real world estimates of altitude) Does it sound like I am doing anything wrong or could do them better? Our club is mostly nitro, with a growing electric presence, so there was not much sailplane guidance available (but a lot of willing help with the line) Thanks in advance, Vince __ Yahoo!

Re: [RCSE] New experiences and questions
Thanks to everyone who has given advice. I have been in contact with Jim Carlton as many suggesed. We will try to get together when the weather gets nice again. I was also contacted by former members of the Wadsworth club, and the club is still active! METRO RC FLYERS eluded me on the AMA site because the president lives in Clinton Ohio, and nothing on the club information piece mentions Wadsworth. So, I have a group of local flyers to help me and a local place to fly ( 40°59'22N, 81°41'38W for those who want to google earth it) Again, Thanks! Vince __ Do You Yahoo!? Tired of spam? Yahoo!

Great story man, brings back some memories of my own. Without a zoom launch at the top, a 510 foot histart, and a mild headwind, am I really about 500 feet in the air? (I am trying to come up with real world estimates of altitude) I like to use a LoLo or a Picolario for height measurement, but maybe you could find one of those cheap altimeter watches and place it in your model just to answer your questions.
