As I said in my reply, there is no manual available for download and all we can go by is the picture shown in the review as indicated by Bruce.

Perhaps it might be best to take it to the local hobby shop and ask someone there, if it's an RC aircraft shop that is, if they can possibly assist you with this. Or maybe someone at your club that is an experienced builder. Without actually seeing the model, nor being able to download a manual to look at, most of us may not be able to help. Someone that has built one may be able to give you an idea of what to do for this problem.

These are not very forgiving aircraft for a second plane after a trainer. The UltraStick behaves much differently than one with a wing shape as the Giles 202 does. If you fly this to slowly on approach, you may not be very happy with what happens next.

You may be wise to put this one aside until you get a little more understanding on how to assemble it and then how to fly it.
