The NXP Drone Team are hoping to make a low cost tailsitter VTOL to allow STEM and other experimentation using the RDDRONE-FMUK66 from NXP. We will be working with the team from Flitetest on this and will re-purpose some of their foamboard wing designs (see the images below).
We want to follow best practices, but do not have a lot of experience with VTOL. One of the goals is to also (hopefully) have it breakdown to “carry on luggage” size.
It was suggested it can be difficult to transition from Vertical to Horizontal flight using only ailerons? I don’t really think we can accommodate tilting rotors, but if it’s deemed necessary we will address this.
Q1) Would two stage ailerons work (I’m thinking of a mechanical linkage so the last 20% of deflection is amplified?)
Q2) Another option would be to put two sets of props on the leading wing (i.e like a quadcopter). this seems to have some advantages in terms of simplicity, and spreading the thrust requirements over more - smaller - motors and props. Apart from mechanics and damage if/when it tips over, Are there other known disadvantages?
Q3) I always seem to hear people talking about airspeed sensors in connection with VTOL - is this an advanced need, or are we going to need to think about including one from the beginning?
Q4) ANY other advice is welcome. This is new to us and we want to experiment. We hope this can be useful to the DroneCode community.
(Below is an example of the construction. This FliteTest material is surprisingly strong, and is easy to experiment with. We’ll use some of the same elements in our design. Of course power pods/props 2 (or maybe 4?) will be mounted in the front.)
