Info for launching a Bob Martin Mystery Ship

Can anyone tell me if a Bob Martin Mystery Ship can handle a winch launch or does it have to go up on a High start? I have a new one just off the board and am wanting to put the maiden voyage on her! Thanks for any input!

Chris,
First, welcome to RC Groups!
Second, congratulations on completing your Mystery Ship!

You're probably more likely to get an informed response to your question if you ask it in the Sailplane - Thermal Forum.

My personal opinion? If you tap, tap, tap, the winch pedal, you can launch most anything. My Bird of Time was winch-launched many times. But you have to be gentle!
Tap, pause, tap, pause, rinse, repeat.

A winch offers one big advantage over a high start:
You are not fully commited; if things go awry on the launch, you let off the pedal, and push down stick, and slid off the ring.
Not so with a hi-start. Once you let go, you ARE commited until the rubber is contracted.
As Roccy mentioned above, just get help from other locals that have a winch, they will know to be gentle and tap the pedal for you.

What's going ON???
A brand new member posts a question in the wrong forum and instead of being ridiculed and brow beaten he is given sound, concise advice???

Welcome Chris. Would love to see a pic. Of your bird.
Good luck with the maiden.

How about this:

I'll report it nicely to a moderator, asking the thread to be moved to the "Thermal" or "Sailplane Talk" forum.

I'll do this so that it will get more attention to the details that our Newbie is seeking.

Request sent....

I did the review of this model when it came out. Yes it will handle a winch launch with a mild zoom at the top. If you didn't add carbon to the spars, the above applies. It also flies well on the slope. George Voss

I guess the Mods figured that it isn't worth moving this thread....

If you don't have a bit of experience with some other glider, this is probably not the one to start with.

I flew one a few times, but it was pretty heavy.

No problem on winch if you know how to tap and if it's well built. (The better built, the less carefully you have to tap, and vice versa.) Suggest turning off winch and practicing tapping while holding stuff in your hands and looking up, without a glider to break. You will look silly, but not as silly as if you were breaking a glider. Or practice someplace in a closet if you must not be seen doing something silly.

This glider is a lot stronger than a Gentle Lady, and I've launched one of those quite a few times off a winch.

Not to worry. I have flown mine off the winch many times ...no problems. I did put carbon fiber on the spar...but it is a well built model. A bit tail heavy..but it flies ok.

If it's reasonably well built, it will stand up to a high start or winch no problem.
As already mentioned, tapping is the key. I have launched mine on a winch many times, without mishap, and it is built as per plan, without any extras in the spar.
Also agree that a winch is the better way to go, like the other poster mentioned, with a high start, once you let go of the model, you are just along for the ride...

Finally, you can do away with all those doubts, and do as I am right now, and build an extra fuselage for it with e-power..
There is a build thread about it in the electric sailplanes forum: http://www.rcgroups.com/forums/showthread.php?t=1596015
