I agree with Gravity. I've flown just about every weekend for the last five years and own balsa planes (300 Edge, P51 Mustangs, Telemasters, and just about anything with wings) & I also fly SPADS. SPADS are a little heavier than balsa but DO fly very nicely. I have two SPAD Spadets (they are about the same dimensions and configuration of the LT40) and they fly very well and are comparable to the LT40. One has a pair of water floats and the other is used during the year for aerial video shots and has been flown on snow with skiis two years in a row. I am the VP of the Des Moines Modelairs and our club has about 120 members. Some of them have spads but those that don't at least refrain from impolite remarks.

I put together a Ultra Spadstick in 7 nights time and flew it with a G38 Gas. The video below shows how well a SPAD can fly. The ailerons are set at low rates but on high, it really rolls.

I know this probably won't convince naysayers but it's really meant for those who want answers from people who fly both balsa and SPADS and can make an "informed" response:

I have tons of videos on my FTP site showing SPADS in flight so take a look. Seeing IS believing:
