A good guess would be about 30-35 mph though.

Mid-30s with a stout pack at lower elevations sounds about right to me. With the 2300Kv/5043 combo & a healthy Hyp 240 2s pack, my Beast 3D is visibly faster than, say, the UM Sukhoi XP or UMX CC, but visibly slower than the Sbach. Elevations where I typically fly range from 910' to 1070' AMSL.

130 ft above sea level in Florida ???? Are you flying from the top of a three story house?

I thought maybe you were standing on your toes on the roof of City Hall, but I guess I was mistaken:

Lol that's your maiden? Normally I'm slow and steady till I get her trimmed and have checked the flight envelope and characteristics. I guess full throttle works too Nice vid.

After 41 years of RC flying, I find that they either fly or they don't. In the case of the UMX Habu 180 DF it has AS3X, and it is amazing how solid this makes a tiny airplane feel.

That being said, you almost immediately get stick-confidence above and beyond the time you have been flying this airplane. You also can quickly feel you have been flying this aircraft for quite a while.

I would add that I had some side-bar fun in that I had an original HABU and my old HABU-2 in attendance. The ARF EDF's fly great for me and the Micro EDF Habu was just as good if not a bit more nimble.

A pet peeve of mine is that manufacturers produce videos of their stuff being flown by real experts. So I go out and see if it can be done by us mortals. A classic was the UM T-28 doing all sorts of inverted stuff. Turned out that the T-28 could do all that the video claimed.

Based upon what I experienced, the UMX Habu can really do it all as well.

I agree, if it's a mfg'ed plane then it'll fly , or it won't. Scratchbuilds are kind of a different story......

Also, your claim about experts flying is why I watch ChuckTSeeker's videos. He does a fantastic job of what the everyday Joe can expect from a plane.

Yup.
Chuck's videos are a better insight into what us mere mortals can expect from a plane!

As far as your situation.... I'd be hesitant to jump straight from the UM T-28 to the Habu. The speed range of the habu is probably 10mph-50mph. The UM T-28 can fly quite comfortably at 3-4mph, and tops out about 15-18mph. Basically a HUGE difference. Combine that with the lack of propwash and the low static thrust of EDFs and it is a recipe for getting behind the plane and on an EDF that is bad news.

The important thing to remember is you are no longer using the throttle for power/speed. You have to learn to use the planes energy. Trading altitude for speed or speed for altitude. Obviously the throttle is important but learning to manage energy is extremely important. Tight turns also drain energy, so make the turns smooth.

It can be done however I'd make sure you take it to a really large open area and keep that speed up. Don't try to slow fly like the T-28, keep it flying on the wing. Also fly it on low rates. Even on low rates it is extremely responsive, MUCH more-so than the T-28. The benefit is that on low rates you shouldn't have to worry about highspeed stalls from to much elevator.

-Brian
I agree. I know for me what helped was that for one thing we fly combat wings which are high speed yank and back planes so going from a 80 MPH wing to and edf was a smooth transition. I also know that I have spent extensive time on the simulator getting used to the take off, flight , and landing characteristics of an edf versus a prop plane so that helps too.
I love flying the baby Habu but it did get some getting used to a jet.
