I got a BT60 full size Omega some time ago and started building it today, I was so surprised with the problems I ran into.

The Sustainer fins root tabs are off set and only go in the sustainer one way. The Booster fin tabs are centered and the fin can be flipped in either direction.

In may case, both the booster tube (BT60) and the Sustainer tube fin slots are off by about 1/4". In other words, the fins align only about 1/4" over hang below the bottom of each tube.

The other problem, if I follow the instructions, the centering rings that engage the fins want work at the locations shown in the instructions, not even close. The centering rings with fin tabls go near the end of the motor tube tube, just over the end of the E engine hook is which is 3.75" long itself.

Using the booster for an example. It's body tube is 5" long. The fin slots are go up the tube from the aft end 2.75". The Engine hook by itself is 3.75", putting the aft Center ring with slots over 1" away from the fin tabs.

Same is true with the sustainer motor mount to.

Look at page 4 step 14 and notice that the forward centering ring with fin tab locks is about 3.50" back, with the engine hook flush with the bottom of the booster tube. The slot only goes to 2.75" max. The centering ring is over 1" to far up.


I can work all this out, just wondering if anyone else has built one of these and have run into these problems?
