Twin fpv?

Looking for a thread on a twin 280 FPV aircraft made from balsa. Another characteristic was that it had a T-Tail. Also, it was a trike LG set-up.

Thanks for the help

I am working on a twin design (build it over the winter) but it will have 2-wheel landing gear to keep the drag down. Those nose wheels and the coil spring strut really adds a lot of drag.

Whatís the reason for wanting a T-tail? I was looking at that option but the extra structure will add weight. There are always design compromises with any design but Iím not sure what a T-tail will buy me?

I like the design of the T-tail. A navy pilot told me it cuts down on vibrations in the aft portion of the aircraft. Sometimes I fly in this King Air F90.

The aerodynamic answer is that it gets the horizontal stabilizer up out of the wing downwash but you have to have much more structure in the vertical stabilizer to support the load. But if you like the looks go for it!

He considering $700 US for an ARF (airframe only). Out of my budget.

Here's my twin speed 280 trike FPV airplane

Here's my twin 280 FPV airplane with steerable nose gear and spring loaded landing gears. Small enough for local park flying.

Advantages:
extremely quiet, efficient (20 minutes, 2S 4000mah), slow and scale like flying characteristics, flys in circles at approx. 5 meters while maintaining altitude, and with the high wingloading, it's a thrill to fly high and then shut off power to try to glide the airplane in for a landing.

This the result of one year of trials and testing and so far this where it has gotten me: an airplane that's easy to repair, durable, and perfect for my craving for scale like FPV. I like taking off and landing at different locations to simulate scale like
Airport take-off and landing.

"Airport FPV" with my customized RC airplane flying LOS-HD (13 min 30 sec)

I have a twin engine Slow Stick using the Radical RC engine mounts. It works great. My range is about 4 miles round trip with 3S 2600.
