I hope to finish building it this week and get it flying. I'm not big on "maiden flight" videos so I won't be making any of those but I'll be reporting on progress and show some all out videos in the near future

The final weight of the model is 11lbs 6 oz with no fuel, standard SAB blades, telemetry sensors and the Hatori muffler. I think that makes it the second lightest model that I've weighed.

10oz of fuel weighs about 7oz so all up ready to fly weight is less than 12 lbs. Thats using a li-ion battery, could probably save a little bit there. No special tricks or using lightweight servos.

the release date hasn't been announced yet. I'm not exactly sure how many of these are flying but I know Joey wants to make sure when its released it will have been tested pretty well

The model is very smooth even at 2100 RPM

What do you think about how it flies? I noticed is another thread you were thinking of changing out the motor with a different TRM motor.

having not flown a Goblin before I found it to have a slightly different feel than some of the other models I have

I've been flying it pretty regularly without any issues however I need to get it into some younger hands

As this is still a prototype, its purpose is to test various configs and combinations. I initially installed a TRM VX270TT and didn't encounter any issues so I progressed to the TRM VX290SE to see how it likes the larger motor. Only a few flights at this point but its still holding up okay

Did Jordan have any comments on the heli? I haven't seen a lot of gas helis fly. How does this compare to other gas helis? How much of a difference does the VX290SE make in the heli?

It flew pretty smooth, this is the only gas heli I have flown so I cant compare it to others.

its hard to objectively quantify but I would say it didn't fly much differently than it did with the 270 that I had originally installed.

Carey, has the design been finalized yet? I know this has been asked many times but do you have a release date?

Thank for the video.

There may be a change in drive ratio but I don't know that there's anything else that needs attention

release date - I don't know

With the extra weight of the engine and fuel (although it gets depleted in flight) compared to the standard electric setup, these reinforced skid supports may be a good upgrade over the stock supports.
