Roban 500 size ah 1 cobra fuselage

[John cheong]

Can I get some advice from u guys . I own a roban 500 size AH 1 cobra but I’m not sure what trex mechanics fits in only the trex 500 esp and the hk 500 tt but both are out of stock and discontinued product . Can a trex 500 pro dfc fit in ? Or have to find a trex 500E . Also which fbl rotor head suits well . Trex efl is hard to find what else can I use . Thanks for all advice in advance

The best option is to find a used Trex 500 ESP. They pop up in the RC groups classifieds and facebook marketplace pretty often. There are other clones of the 500 ESP available as well, the chaos 500 being the best quality: https://www.scaleflying.com/500-Mech...D-_p_5170.html

The HK 500 is also still available (same as the Gartt 500) on aliexpress: https://www.aliexpress.us/item/32568...d=MXSGlOAtFgHJ

However, if you go with the Gartt, I would strongly recommend replacing a few of the rotating components with Align parts including: Main gear, Main shaft, torque tube, and torque tube gears.

The chaos 500 does not come with 500 rotor head ? Is the 600 rotor fits the chaos 500?

Heads are fairly easy to find. You can get any number of different clone rotor heads off of ebay: https://www.ebay.com/itm/22447577061...4aAnxyEALw_wcB.

I kinda like this
SG$ 62.03 | GARTT 500 Flybarless Helicopter Main Rotor Head for Align Trex 500 Kit

https://a.aliexpress.com/_mMBqugM

and also the tarot
SG$ 60.54 10％ Off | Tarot 500 Flybarless Main Rotor Head for Trex 500 Helicopter Black and orange color

https://a.aliexpress.com/_msH59uo

but I think it should look better in the gartt cause of the full black colour suits the whole camo and black appearance. Any comments on these 2 before I place an order

I've flown both the Gartt and and the Tarot heads. Both are decent quality.

I think I’m leaning towards the gartt 500 due to it’s costing is cheaper and I can get 2 frames 1 for spares . Do you mind sending me the link for which parts to be changed on the gartt to the aligns ones ? I would order 1 time
