Hi

Has anyone used one of these type of flight stands?

http://www.rcuniverse.com/market/item.cfm?itemId=248532

If so:
- Is the stand only for mounting the plane for repairs etc?
- Can I safely start my 40 size Sig rascal on these stands, run it in idle ?
- With weights (like toolboxes) in the trays below , and by strapping the plane with a rope to the bottom part of the stand , can I test the engine with full power for a long time? Will it topple the stand?

I have a plane with an inverted engine, which stops a lot of time, thus its painful to bend a 100 times a day in the field! A stand will help.
Is it safe to start and run engines while in the stand - has anyone done this type of thing??

Pls advise and share your experiences/thoughts . Thanks
