Yes, there are one of the best nitro helis on the market today
They compete nicely with the Synergy N7, but they are a little heavier
They are way better than the Trex 700XN
I bought a Goblin 650 Black Nitro and after about 10 flights, decided to buy the stretch kit to 700.
The 700 size with the 690 VTX blades and a YS 96SR-X is the bomb.
No problems with the belts - they are not exposed to the nitro residue anyway.
I just bought a donor-copter Goblin 570 with plans to use the JC Designs Goblin 570 Conversion to Nitro.
I'll move the YS 96SR-X out of the 700 and replace it with a YS 120SR-X, then use the YS 96SR-X in the Goblin 570 N.
The headspeed will be 2600 - that will pop for sure.
Believe 1/2 of what you see and none of what you hear.
Fake News will be the downfall of our Republic!
