The 6th Annual CAFE Electric Aircraft Symposium, coming up April 27 and 28 in Santa Rosa, Calif., will feature speakers from NASA, Boeing, Aerovironment, leaders in battery technology, and more, the organizers announced recently. Tine Tomazic of Pipistrel will be there to talk about the Taurus G4, which won last year's $1.35 million Green Flight Challenge. Mark Moore of NASA will discuss advanced concepts in electric propulsion, and Tom Gunnarson of FAA's Small Airplane Directorate will explain the agency's plans for certifying electric aircraft. The weekend is billed as a "graduate-level program" in new flight technologies, featuring experts in lithium battery research, design software, UAVs, quiet propellers, and high-lift aerodynamics.

It has been very interesting watching these companies evolve over the past few years. China based hobby companies began by offering poor performing, clunky model airplanes at a very low price, but have steadily improved on each generation of warbirds and jets, resulting in great looking models with amazing scale features. I have flown the Airfield 57 inch P-51, and Bf-109 from Nitroplanes. They are very scale, come with all electronics installed, and are under $300. While they look great, they perform “marginally” in the air. The all foam wing without a main spar results in a “flexi” feel in the air. The power systems are more than adequate, but the scale multibladed propellers reduce the speed considerably, and make for wild takeoffs from the added torque, especially the 4 bladed prop on the Mustang. On the plus side, the stock spinner is set up to accept a 2 bladed prop as well. With that being said, the larger jets perform much better, with their shorter, stiffer wings and efficient EDF units. Jerry Leister’s F-22 is a nice flying jet. The latest F4U Corsair from Banana Hobby has raised the bar again. The larger size results in a stiffer airframe, and they keep refining the foam composition to get increased rigidity and a smooth finish after paint is applied by the factory. The electronic folding wing is amazing, and the retracts are aluminum electronic units, with sequenced gear doors! It also has a sliding canopy, navigation lights and scale bombs and rockets! It looks like the performance in the air will be better as well. Jerry Leister has purchased one for his “Jair Force” and we’ll have it up at the field soon. Banana Hobby also has a 79 inch P-40 coming out soon, and it is incredible!

These companies are certainly becoming a player in the industry and are worth taking a look at.

I definitely agree with Jake! Racing classes that have strict requirements in regards to airframe, motor, and prop will have the most participation and closest racing. Pilot skill determines the winner. Racing a plane that I haven't spent tons of time on allows me to fly a bit harder, and reduced build times keep racers coming back after a crash. This can be seen in the T-28/Corsair class currently. Tech inspections would also keep the racing close and honest, and clear up any confusion on what is allowed before the racing starts. I'd like to see a Dogfighter class with only one motor and prop option, the fastest of course! That would make for an affordable, low time investment, exciting, and fast racing class!
