Pig Soooiiieee!!
Great models.
If you think the model is very sensitive on boost, you can either 1)add nose weight to make it a bit less tail heavy, 2) use dual rate and set up your boost throws to be a bit less movement, 3)use expo so that throw around center is less but you still have full travel when needed at the extremes.
Did ypu wind up laminating 6mm sheets to double the thickness?
Yes, I've got plenty of the 6 mm sheets and they are large enough that I do the whole wing, so there are 2 wings laminated together. I used 3 spars of hollow graphite 5/32" dia. rod from Central Hobbies in Montana. I was thinking that the c.g. should be similar to the Orion. Possibly, I could use an estimated c.g. estimated from the SST plans, but my wing and length are not exactly the same. The overall length is the same as the Orion. Any suggestions for the c.g. would be welcome.
I just checked the Dynasoar website & see that the Orion Starliner is no longer in production. I did find the assembly instructions for the smaller version but no drawings for making the wings/tail. I'd really love to build & fly the smaller version. So my questions are:
1. Are the dimensional drawings avilable somewhere?The OS is one of the most elegant birds I have ever seen.
2. Can the parts be bought somewhere?
If you can measure the wing I need sort of the root cord the half span and maybe a couple of measurements in between so I can approximate and I can give you a starting point probably
Here is yours, with 18% MAC for CG, note the cg location is 12" from the front of the wing where it hits the fuse,
Bon Chance!I got decals for the Concorde SST from Sticker Shock. As mentioned before the design uses the same basic technology as the Orion Star Liner. The Concorde c.g. looks pretty good. It is about 12" back from the front of the wing. The full-up weight with loaded G12 motor, battery, servo's, the receiver, etc., came out pretty good. It is about 23 oz.
Unfortunately, my Concorde SST, which was my own design, crashed beyond repair last Saturday (May 15, 2021). Surprisingly, my wife caught 2 still photo's of the glider after ignition. Shortly, after lift-off the rocket went straight up, but soon after about 100 feet or less the glider arced over upside down. I don't think I touched the stick at any time. The model flew overhead upside down and there was nothing I could do. My response time is just not quick enough. I looked at the G12 motor after the flight and I did not see anything wrong. The nozzle looked fine. I think the 2nd flight picture shows the glider just about starting to arc over. The battery clip on the micropeak broke. I think that Altus Metrum can repair it and they might be able to retrieve the data. I am not sure that they can. I tried to retrieve the data and I could not.
Yes, exactly, it did pitch back towards me. I thought about that today, if I had been collected and had some presence of mind, I could have used some down-nose. If I had given it some down trim early, I might have been able to recover the flight. I wasn't expecting this, so I wasn't prepared. This was my second glider flight of the day, so the prairie winds may have been kicking up. The Klingon Cruiser was way more forgiving. I still have the Orion Star-Liner and G12 reloads. I tend to think that the wind is better on the Salt Flats than our Frank Hunt Field (Pony Express Range).Bummer looks in the photo like it just pitched back at you, probably just needed some down trim, these really need full pilot control on all phases of flight to keep on top of them due to wind etc, it's really hard to let them do their thing and then react afterward, sorry about the crash.
