100mph - NTM 35-36 1800kv on 4S
85mph - NTM 28-36 2200kv on 3S
I love my 800mm FT Spitfire so I figured why not make an 800mm FT Mustang?
I added an aluminum spar and am flying without a rudder or landing gear. Other than that it's just scaled down compared to the original.
I have added the plans here.
Works great for acrobatics and fighting the wind.
My 'hangar' at the moment
For an 800mm plane it performs well. It is quick, light in the air and doesn't stall very easily. It looks great and I would give it a B for high wind performance. I flew it today in 15 MPH wind and it got tossed around pretty good but overall held its own. Inverted was great, it liked being upside down.
Slow speed - Not great. I had a few close calls with slow speed stalls. Made landing a bit tricky.
Glides - I dropped speed really fast and had to give a lot of corrections to keep it straight.
Elevator - This bird suffers from the squirrely issue that some warbirds run into where giving it 'too much' elevator will cause a weird tippy, stall type behavior. I had to dial back my elevator quite a bit to get rid of the issue, to the point where I didn't feel like I had enough control over the plane at all times. I could still fly fine but I lost a lot of acrobatic capability.
All in all
I like it. The cons are workable and it's fun to fly. I like how it looks in the air and I got a lot of compliments from other pilots. The 800mm FT Spitfire performs better in pretty much every way so that will continue to be my main go to plane for now, but I won't be putting the 800mm FT Mustang away anytime soon.
I decided 100mph wasn't quite fast enough and I want to push it further, can I get to 110? 115? I don't have a better motor I can use so I'll be sticking with the 35-36 1800kv for now. So my only option is to streamline the build. Here is what I've come up with so far.
Elevator servo, RX, GPS, and battery telemetry will fit inside the cockpit.
I added the front cowl covering and included a scoop.
I removed all under camber and brought the trailing edge to a pointed finish. I also removed the open scoop on the belly.
Wing tips came out real nice and clean. And as always my signature blue canopy
The build went really smooth and I will be doing her maiden flight soon. I will have a video to share in the next day or so.
How do you guys think she will fly?
djacob7 from RCGroups saw my V1 build on rcgroups.com and was very interested in seeing how V2 progressed so he actually met me at the field and was nice enough to film the maiden. Thanks djacob7!
