< since most conventinal planforms use dihedral or roll axis CG located below centerline, this doesnt tend to show up often.>
I need to look at that roll axis CG relative the centerline...
<Ill still use two stabs just for the cool looks, but likely use shorter span and longer chord.>
On the stabs...or wing...?
<So, how many good flights did you get out of your Wasatch clone?>
I got probably around eight....with two crashes.
Flew very nice on a G with short delay...but one of the G flights saw the Klett hinges on one elevon pull out of the wing on the way up...with that went the single rubber band actuator stretched between the two elevons..w/o elevons actuated - it arced and nose dived all the way in but survived with just a small crimp in the BT.
<Also, what happened to your last H97 flight? Did the elevons NOT raise after pod ejection? I can see a broken band, but not TWO at once!>
Flights at Red Glare V included a very nice long slow glide off another G motor..then I got balsy and put the H - 97 in.
I didn't know how weak the hinge points had gotten over time...pink foam did not take epoxy and CA very well, and even with new monokote hinges as a back up - and the fact I also pinned the hinges into the foam with wooden pins...the force of the H-97 was significant...
The elevons were found near the launch pad and it proceeded to do an agressive slow arc out over the corn fields and impacted...splitting off a wing.
Repairable...but the conical exhaust end of the body tube had seen significant
delamination inside, making pop/pod ejection increasingly difficult.
I even had a small fire in the rear exhaust BTduring glide after pod ejection...providing an interesting crowd pleasing display late one winter afternoon...
<My BT-80 Concorde (which is basically the same size/type as yours but very lighter) still does well on F motors, even though its last flight nearly went bad due to a freakish rod whip slamming it off course. Its thin walled tubing is getting pretty cooked, so this may be getting replaced after a few more flights.>
I have yet to try the SST-lite you suggested on the old forum...I think I wouldlike to have one...rediboard,...any source online?
<Please post build threads of anything you do, and if I can get a camera, I will do likewise. >
Will DO.
