Hey Gary... No I have not heard of them... I can ask around and see, I'll post
if I hear anything... That said... Our club was invited to a private airport(Eagle)
to fly along with other things going on about a year ago.. Anyway this person
from Havasu brought "His" 540.... It looked like your pic... Not saying it's the
same plane.... I asked him where he got it, and he replied that it was "their"
proto type and that he and a few others where going in to market if all things
fell in place.. That could be the outfit??? He did not put it through it's paces.. So
I can't say anything about it.. except it looked to be a well put together model.
Anyway, as far as I know Havasu just closed it's only RC... "Airplane" hobby
shop As was reported from our last club meeting.. I know, If your not in any
rush I can contact that person once I get back home (still in Vegas) and see
what he has to say.. He came to our last meeting to invite us to Eagle field
airport to fly(along with lunch) at his grand opening of his hobby shop... That
was/is Today.. But I'm in vegas...So I did not make it... Anyway I'll call when
I get back... If I remember correctly he said that the person that owned the
hobby shop that closed was going in with a group to market something??
Anyway I'll let you know what he said...

Gary... Just looked above... Tell me that is not the only reported "Do-46-100"
If it is.... Man Sorry!!!! But man I'll be the only "Speed Nut" now... Sorry Guy!!

CeeGee... I'll post when I get back Home.....
