Tomxl3's HK250GT / 250T-Rex Align complete tail upgrade!

[tomxl3]

hi tony and others here this is my souped up !HK250 GT maiden after the upgraded tail same problems that you had with yours tony so it cost me about another $100 bucks to get it working rite but fly's great now
The original belt broke on first spool up so that's when i decided to change the whole tail to align with the Chinese weight upgrade ! the tail itself on my kit was good because i used red locktite on it but after a few flites it got loose and i had to keep an eye on it so i opted the for the align one piece pitch slider arm mount and it fly's great now enjoy ![video]http://www.youtube.com/user/tomxl3?feature=mhum#p/u[/video]
p.s the real T-Rex 250 SE is in the basement in the works! could of saved a few bucks buying it in the first place LOL!!

Sorry about this being moderated, it shouldn't have, and I don't know why it was. Also, I added the embed code to your post. That way, those of us that have iphones can watch the video. For some reason, when you link to a channel, you can't watch any of the videos on there...

 

[tomxl3]

thanks man!!

 

[Tony]

Watching the video now on my phone. Man that is one of the most stable 250's I have ever seen. Can you give specs on the motor, servos, esc, gyro, and everything else? Maybe some good pics? I'm very interested in this now. Great flying.

And whoever was sitting in that chair did not look impressed with you flying in the house lmao

 

[tomxl3]

theHK 250 GT has a bad tail design the boom clamp is too small for the boom and also the belt sucks lasted one spool up and shredded to pieces the tail is not so bad if you use red locktite to hold it together they are known to fall apart!
mine almost did till i did a check and seen the screws were loose so i replaced with new align one with Chinese weights also a big warning the feathering shafts are very dangerous please use align ones because if you don't like knifes flying at you! change it!!! so you can call it 50% hk250 gt /50%trex250 Frankenstein LoL but Flys great! here are the specs

That sounds a lot like my setup. Same motor, same esc kinda, I'm getting to where I don't trust teh Rx's, but I will still put one on this little guy, I have two of the mems gyros on the way, one is for the 250, looked rock solid. But, I'm going to order some MG90S servos for it. Overkill? Yup lmao. But, they will never go bad lol. I will also be upgrading a lot like you did to get it to fly correctly. Great Heli.

 

[tomxl3]

here are a few pics for ya Tony anything you need to know? or see just ask

 

[tomxl3]

for the mems gyro you can only use digital servos is the MG90S digital?

 

[Tony]

Ah, didn't know that. Well then, I will be looking for a better servo lol

 

[Tony]

The pics look great. The only thing that I would do different on that heli, is move the balls in on the servo arms to get the links a little more straight. Other than that, man it looks great. I can't wait to get mine in the air now...
