reefguy, my opinion...........

Stay away from TSK. They are out of business and parts will be an issue. Lots of good buys, but now you know why.

Your X-Cell, although old, will still fly fine. Although you may have to replace older parts with current version part, you will be able to repair the unit. X-Cell is the only model I know of that has maintained parts replacement/upgrade from their first to their current model.

Do you have the plans that came with your X-Cell?
What is the date on the plans (1987 or 1993)?
