I am so friggin glad i didn't buy this P.O.S. system! After watching those video's , looks as though XJET was right all along. As far as i'm concerned i think mister JD is a fraud , and a liar. The ONLY thing i can say is i feel bad for those guys who bought into his deception. What a joke. I can't wait to see the tests on the JR , Spektrum and fasst systems. I think these three will all perform well , just like they are supposed to. I think i may be getting the new futaba fast moduel for my 9Z , but i think i'd feel safe with JR or spektrum as well........they've proven themselves. Can't wait for the tests though.

Ya know, I understand everyone getting PO'd about JD and the XPS stuff not being what was claimed. But c'mon Jeffro. . the name calling, albeit probably accurate. . is it really necessary?

Okay. . Isn't JR just using the Spektrum firmware, software, and design pieces to put into their own systems. . or is the JR setup totally proprietary from the Spektrum stuff?

I thought they were basically the same, with differences only concerning the radios they must work in.

Am I sorry I spent my money and possibly lost a plane to it (since I cannot 100% determine that).....actually no, I'm not sorry I tried it. It does suck the time and money I was out but I never put anything in the air I cannot afford to lose.



But that is just me. Everyone will have their own thoughts.
In this hobby money spent has already been lost. Might not can replace what ya bought, but the money was already "afforded".
It's the windshield or the kids use of his left eye that has not been not been afforded.
These things are potentionally lethal from I'd say .25 cc all the way up and any safety measure taken with one should be taken with all.

Ok......maybe the name calling was a bit harsh , but honestly , the guy lied about what his system does , and doesn't do. There for taking the money of many people whom believed in him.....which , isn't that called being a fraud? I know it may seem a bit harsh , but those two words "liar" and "fraud" seem to be the only two words i could come up with that fit the profile. He sold a system ( probably thousands of them) , made his money , and now , i'll bet you money , he'll run and hide and won't make it right. I know from reading other threads about JD in other hobbies ( like paintball for instance) he did the same thing. Made some new "change the friggin' world" paint ball gun , and when it became obvious that it didn't work worth a crap , he bailed out on all those people as well. he also had something to do with something he created in the computer industry that didn't work out , and guess what....he bailed after he got all his money.

see a pattern here......??

JD will be facing some law suits in the very near future.
Don't ask me how I know....

Well, it hurts have lost a nice new big plane, but I am so.... sooo glad I was alone and nobody got hurt. Man you guys when that plane when in at that speed, it was a scary ,scary thing to see. PLEASE tell others that are using XPS of the inherant dangers, you really could be saving someone from causing, huge damage,injury, or (God forbid) a death. I am out allot of money(plane,engine repairs +shipping from Canada and prop,spinner switches etc). At least nobody was hurt and no other property was involved. My XPS system is NOT FOR SALE and WILL NOT BE USED BY ME,unless there are safe and verified changes made to the system. Brad

i tryed to tell my flying bud to take a look at this thread which, by the way is or was using the xps on his 33% sd extra w/da85 it is now in the grave. most guys wont listen until it happens to them. he now has swore off gas planes and has gone back to the little stuff. which i guess is for the best. if you cant afford to loose it you cant afford to fly it. anyway iam glad i did not fall for it. i almost pulled the trigger on this system because of the price. shure glad i didnt. i wish the ama would make a call on the radio b/s and either say 2.4 or 72. one or the other and be done with it.

This may be a stupid question but if a Fasst system and an XPS are flying at the same time does the XPS loose signal breifly when the Fasst cycles through the frequency the XPS is on and if 4 Fasst's were flying would the XPS be jammed and loose signal more frequently.

So what does this mean with the XPS system? I have the directlink about 50% installed in my smaller plane but I havent flown it yet.

That's an interesting question. even if it did, Fasst is only on the freq for a fraction of a second which isn't enough time to go into failsafe...it should cause XPS to retransmit a packet. I would think this would be similar to one fade like on Spektrum.

Doesn't XPS/FASST/Spektrum use a unique code so they don't interfere with one another? The real problem XPS has been encountering is higher powerlevels than R/C transmitters. When Kiwi is finally able to test we should see exactly what power level will negatively hurt XPS and the other systems.

Yes they are one in the same. XPS stands for Xtremelink Power Systems
