Hi,

I'm currently looking for my first 90 class nitro heli.

First, I was going to buy the Trex 700... but, 4 guys in my club and even one Trex 700 owner, advised me to have a look at the RJX XTreme 90.

About the same price, but better quality.

It really seems to be a killer machine, but unfortunately I can't find much information about it. The constructor website is poor. And I don't know if this is really a good machine...

What do you think ? Does it worth a Trex 700 ?
Are there better helis in the same range of price ?

Thank you

X90

the X90 rocks although there aren't a lot of them out yet as Rjx hobby had a short fall on the x90's TT they held it back until they got it working correctly. I have the g10 version with the belt drive tail and it is very fast in cyclics and with the RjX muffler on the YS91 it is on crack. For the price and what all you get with the metal head and all ,you will love it for sure.

Buy one you will like it!

I own two Extreme 90's both tt drive. They are both outfitted with
the YSSR engine's,one with the RJX pipe, one with the SB19,8717's on cyclic. This machine performs has good if not better than my synergy's i sold. At half the cost, because there are no upgrades. what you see is what you get. It took a minute to get new gears in the begining but all issues have been addressed.This heli is better quality than the 700n and i have friends that fly them and love them also. Both align and rjx have very low crash cost when compaired to other 90's on the market. You can buy the RJX kit in tt version or belt driven tail. Also CF black, CF silver or g10.IMO with these types of choices and the out standing customer service is hard to beat.

In the end both machines fly great both are cheap to repair. My pic would be RJX every time....
if you have anymore questions feel free to shoot me a PM

Thank you for the usefull answers.

I have some more questions :

- G10 is the best ? Is it the Belt-Drive kit (orange canopy) ?
- Is the Xtreme 90 flybarless ready ?
- If not, what do we have to change ?

I have heard that flybarless is really good
because the rotor head is simplier.
So it is also stronger I guess ?

Black cf is stronger and lighter than G10. if you have not switched to 2.4 yet i would say go with G10 because of radio interference.

flybarless: you will need a flybarless head and the Vbar system. i know there are some other systems out there besides V-bar. just make sure someone knows how to set the v-bar system up because they can be a bear i have heard.

the flybarless rotor head is simplier for sure i dont think its any stronger. Just less things to bend or break in a crash! It will make any heli quicker for sure

Hope this helps

XTreme 90 Belt drive

You said there were two different kits :

What's the difference ? What is best ?

Thanks for your help

TT (torque tube) is the shaft driven tail.
Get the belt driven tail, you will be happy with it

The most important thing is to have an experience nitro 90 flyer to check thru your heli and guide thru the run in.

Once everything is set right, i think you will be in for a very happy time!

Very nice electronics install.
What is that plastic tube on the LHS above the fuel tank?
It has fuel lines going into it.
Is that a home made header tank?

Very nice!!
Did you make that to do away with the anti rotation bracket?
I really like how you have used rubber grommets to protect your wiring.
Very slick

if your just starting out, RJX make some nice fiberglass blades in 690mm.
Perfect practice blade that wont break the bank, and is still very good quality.
690mm blades feel better on the X90, because its so light, if you run 710mm it feels to floaty in the air.
