Tower says mine shipped today with the combo engine and gear....I'll take my time and wait for all you guys to test fly it for me! No really, I'm concerned with gear doors catching on grass runway. I bought the Ziroli Staggerwing kit and he mentions to leave bottom hinged last section of door off if in tall grass. If you watch the TOPFLITE video real close they have the doors off during the roll portion anyway. It is short coupled and I do think it will be a handful on landing.
