Default New Extreme Flight RC 48" Extra 300 EXP Build

Ok guys, I decided to start a new thread for the build to help guys just getting the planes now so they don't have to dig into other threads for info. Please jump in here and post any questions and info you have as well as pictures and videos. I can tell you Chris is very excited about this new release as it is the best flying electric in this size plane that he's released yet. Between the two of us at SEFF we each flew about 20 flights a day there all week. We hammered these planes and they took it with ease. We had no mixing at all in our radios, they flew perfect right out of the box. Here are the specs from the website, just set yours up as recommended and you're in for a big treat.


Introducing the Extreme Flight
Extra 300-EXP Arf
Extreme Flight RC is pleased to announce the release of the new 48 inch wingspan Extra 300EXP ARF.
Incorporating many forward thinking design elements, the EXP is the result of several months of R&D, flight testing and refinement.
Loosely based on the mid wing Extra 300, the EXP has been manipulated to offer the most aggressive flight envelope imaginable.
Following is a brief rundown of some of the unique design features that contribute to the amazing flight capabilities of the Extra 300EXP.

-Forward canopy placement places the tallest portion of the fuselage over the CG, which is optimum for best knife edge performance.

-Huge airfoiled control surfaces utilizing geodetic construction provide the ultimate in yaw, pitch and roll authority.

-Carbon fiber longerons and motor box supports add enormous strength and rigidity to the airframe, while G10/lite ply composite laminates make for a robust landing gear mount.

-One piece airfoiled molded carbon fiber landing gear and tailwheel bracket provide solid ground handling and contribute to the awesome appearance of the EXP.

-Long tail moment contributes to rock solid precision flight performance and tracking.

-Spring loaded hatch latch provides instant access to battery tray and interior of aircraft while providing a solid attachment point for the canopy.

-2 piece wing mounts on a carbon fiber wing tube and is easily removed for transport.

-G10 elevator horn bolts on to stock servo arm to allow for insane elevator travel.

-Rudder and elevator servo mount in the rear of the aircraft and utilize a short direct drive carbon fiber pushrod with ball link for slop free control surface actuation.

-Removable Side Force Generators add tremendously to the effective side area of the EXP increasing rudder authority and improving knife edge and high alpha stability.

-2 gorgeous genuine Ultracote color schemes available with expertly painted fiberglass cowl and wheel pants.

-Complete hardware package and decal sheet included.

-High level of pre-fabrication allows you to get the EXP in the air in as little as 3 hours!


Designed around the Torque 2818T/900 and 2814T/820 (spacers included to accommodate both motors) and Airboss Elite 45 Amp ESC utilizing a 4S 2100-2600 mah LiPo battery
(we highly recommend the new FlightPower EON Lite 2550 packs!!!), the EXP achieves ballistic performance from either motor.

We offer money saving combos with either motor/esc package.
We also highly recommend the Hitec HS-65MG or new HS-5065MG digital servo for control surface actuation.

The Extra 300EXP is by far the most advanced and best performing small electric aircraft that Extreme Flight has released to date. Give us a call or place your order in our on-line store and experience for yourself the incredible flight envelope of the Extra 300EXP.
