3D ! Extreme Torque !

Test Results

If you like power or burn up 3D motors and want something that will last - this is the motor for you. It has a very low KV of 950 - which means a 2850 KV motor would need a 3:1 gearbox to turn about the same speed as the 450XT, but the 450XT does not introduce the inefficiencies introduced with a gearbox, is very quiet and can still run large props. I recommend the 10x6 for park flyers, and lower pitch props for 3D.

I run this with a 10x4.7 to fly my 14oz IFO in wind. When I fly indoors I'll switch between the 10x4.7 and 10x6. I like to cruise around with no worries about sticking the nose up and jetting up. The 10x6 enables me to race the faster planes cruising around the huge armory that we fly in, but still have alot of low speed control.

Impressions of the 450XT

I unfortunately am not a 3D flyer. But I know a good motor when I use it. The 400T was very good on an 8x4, but you guys wanted a 9x5 and 10x4.7 prop for your 3D planes. Well this 450XT will 3D your heavy 3D planes, fly normal planes as a cruiser around your parks and WarBirds can use higher pitch for faster speeds. I don't feel this is a motor for a Wing or a Jet as it will not provide the speed you might enjoy. Try the 400DF or 450TH for the Wings and Jets.

Chris's Glider with 450XT

Saturday I flew with a gent who has an ArtHobby "Castor" 2 meter, which was powered by a Mega 16/15/4 with planetary gearbox ($$$). It's a slightly larger and heavier glider, but I could literally run circles around him. When he found out my power system only consumed 13.5 amps and the motor was only $51 (and no gearbox required), he just about fell over. :^)

Long story short: You can DEFINITELY recommend the 450XT and Aeronaut 10x8 folding prop combination for any glider in the 20-25 oz weight range. Heck, even at 30+ oz I suspect it would do fine, but at 23 oz it
will nearly go vertical. Great fun, and I couldn't be happier.

Video of modified 450XT with the High Speed Bell creates a 450XTF which runs ideal on a 8x6 prop. This video is a 7x7 prop. For high efficiency and good performance - this is the setup. For extreme speed at higher amp draw look at the 450T or 450TH.

 

The 450XTF is 1500 Kv - faster than the standard 950 Kv 450XT - but the 450XT will run larger props very efficiently.

High amps, oddly slower than 10x6.
I Recommend GWS 10x6 DD Prop over this expensive prop.

Craig Thompson's Blue Core 3D Plane with a JustGoFly 450XT.

This is a GREAT motor. I really like the power I get for 3D flying. With no more gear box noise. I am runnning a 11x3.8 apc prop with 1800mAh 3 cell and my plane is 20+oz. email: Craig

Model specs: Model: (.25 size covered balsa ARF) MFG: Shenzhou Nanlong Models (mainland China) Power: Motor Max 450xt, 15amp ELE ESC, Fuel: 2000mAh 3s1p RC-Dymond Lipo. Wingspan: 48" Weight: 29oz. (ready to fly)

The only mod needed was the motor mount. I used a GWS sp400 gear frame on a stick. Its a "true scale" flyer. This means its speed and climbing power are proportionate to the full scale aircraft. With the 450xt and a 10x7 prop we're getting about 70w per pound and 47mph pitch speed.
