Considering which one to buy. Does any body have experience with both and could you tell me the plusses/minusus of each? The HDX website says 90% of parts are compatible with T Rex. What parts are in the 10% that aren't compatible? Thanks.

The owner of my LHS put together an HDX and it flies great.One of the other guys that flies a Trex and whom I consider to be a very good pilot has flown both and he said he likes them both.As far as parts go I can't help you there because I am not sure what is and is not compatible.

Almost everybody I know who bought a lower cost T-Rex spent more in the long run upgrading it as opposed to just buying the SE upfront. I would just go for the SE, it's worth it.

I had the STK frame from HeliDirect which is the HDX450 frame. The one difference is the main gear collar and washer is slightly longer than the T-Rex. You can purchase these from HeliDirect.

It's a good heli and if you're strapped for cash, the HDX is a good heli. All metal bling and I believe it comes with ESC and motor. You can check out those Videos at HeliFre@k.com.

We haven't seen Colonel Angus around these parts for years!

As far as I know the feathering shaft and the tail rotor shaft are HDX specific.
Everything else is the same.
I have a HDX and it flies great, I had to do a bit of work on it, but minor stuff, for the $ saving its worth it.

For the love of the hobby

The STK "G10" frame material is very strong. Unfortunately, I've tested this extensively ! The frame is open and easy to work on. The aluminum head blocks position the cyclic servos precisely 120 degrees apart, so the swash movement is very true.

the flybar teeter is hdx specific as well. i accidentally bought one instead of an align one. it was too long and i had to machine some pieces to make it fit.

i would be wary of buying something from helidirect that only they sell. they are notorious for being out of stock on stuff right when you need it.

The HDX is very good. Have flown 90's for years and just getting into electrics this winter. The TREX was my choice not knowing anything about other E helis. I received a 450 s cf for X mas. It is now a all grey SE. After a friend of mine decided to order a HDX for his store we assembled it and I got it flying to see if this heli was good. Come to find out I now want one and may get rid of the TREX. This heli is awesome for 299. It is basicaly the same as a TREX sharing most of the same parts(look alikes). One of my biggest complaints is the plastic links, for $3 get the align links right off the bat and the canopy which is being tossed for a glass canopy. There is too much play in links and they are a bear to get on and off. My opinion is that the frame on this machine is better than the TREX. I like the lay out and it is easier to work on especialy the servos. Its like my Furys. The HDX with out battery weighed 600G and the TREX was 585G. I have a 149rec in the HDX and the fins are thicker and heavier. Both machine a awesome but for the price the HDX was the best part!
I flew another one today with the silver frame. We got it built on Friday night. I guess It comes with a newer version out runner which had more power the the other HDX. They are by no means power house motors. But it tossed it around the sky pretty well. Not like a 4050 or hacker. Good Luck! Jason
