I am not a member of this group but with all the debate I have considered asking my club to accept them as an alternative to AMA.
I've looked into their insurance carrier (GULF INSURANCE GROUP) and the carrier is virtually identical to Westchester Surplus Lines
Insurance Company that is used by the AMA.
Regarding the two hottest topics mentioned in this thread here is what their safety code says:
8. I will follow all precautions by manufacturers when flying my models with turbine engines.
16. I will not fly my model if it weighs more than 100 pounds, unless I have signed a waiver with UMA headquarters prior to flying.
I know the SFA debacle soured many long time members against alternatives but this does not displace AMA if you charter your field as UMA instead. Both AMA and UMA members can fly at a UMA chartered field. See more information in this overview:
Here are a few advantages with UMA:
Buddy cord or other UMA approved training is okay with non-members.
Complete coverage for fly-ins.
No restrictions as to who flies at your approved field.
No deductible
Family memberships available
Very few restrictions (see Safety Code)
Primary Coverage
General coverage insurance is provided by the GULF INSURANCE GROUP. A $1 million/ $ 2 million aggregate umbrella coverage for UMA members and officers of UMA Charter clubs.
Medical coverage insurance is provided by the NATIONWIDE LIFE INSURANCE COMPANY. Policy coverage is for $10,000 primary & no deductible (accidents only). Accidents incurred when flying at fly-ins or flying day at specified fields (as noted on applications).
It doesn't have a lot of traction right now but if the AMA EC continues along the path prescirbed by Mr. Brown it could get some.
