It would be nice is they sold it without the Tx and AS3X Rx, as I'd prefer to use my own non Spektrum radio.
Looks like it might be a fun little park flyer, even with brushed motors.

Is very similar to my Stratos wish they had the option to get it bnf or I would get one. I am sure it will fly great for all that looking though.

A very nice looking plane. Note that there is no rudder.......yaw steering is by differential thrust. A pair of GWS floats would make this an eye-catching float plane. The differential steering works great on water.

I second the motion for a BNF or a PNP option.

read the parts listing

If you check out the parts listings, you can do one of these up like a striker and just get the foam, I am sure, two little park 250 brushless motors and two 5x4 apc pros would make this scoot real nice

Wow! What a great looking little ship.

I've always loved deltas and I've always loved twins..This one's hitting a home run on both for me!

Looks like the wing fences are optional, as they're there in some of the screenshots and not others. I wonder what effect they have on the flight characteristics..

I also like that the main gear has a very wide stance. I bet this would make some impressive high-alpha touchdowns.

I also like the looks of this Delta. I thought the Stratos was a very nice flying plane and performed well with its brushed motors. I sold the Stratos after a while and I need another trainer like a hole in my head but I am looking forward to seeing this one fly. I may have to buy the foam body and add my own little motors and controllers (which I already have) after everything comes into stock. I am looking forward to the video of it in action. Mike Heer

I want one !

A total newb I'm, an Apprentice S 15e eaten by a local tree (60'+) to vanish days later as proof. But this smaller SAFE delta could be just the ticket to fly by wife - she is not too favorable to my new found hobby : a monster truck early this year, two micro quads in a row (they are still flying) and the almost instantly vanishing AS15e ...

The Delta Ray SAFE is a bargain and should get me back in the air ...

I would consider buying this plane if it had brushless motors.
