Thank you!The description was excellent and the pictures were very clear.
If you do, post pictures!awesome! I might try this with my spare f pack motors, but I'm sure I won't use drooperons yet

The beta plans have been released. They represent the initial plans plus corrections from the experience of building the first test vehicle, and come without a build guide. If you'd like to have a go with these, I'll help you along the way - although you could wait a month for the final plans and build video.
Nice! Got any pictures?I down loaded the plans and built your plane. Went together really well. Have to wait till winter is over before I give it a go but looks like it should be a good flyer.
Little more fine tuning she be done,I just used one rudder in the centre. Thanks for the use of your plansNice! Got any pictures?
Looks fantastic! The three-blade props with the round nose prop nuts are cool as frig.Little more fine tuning she be done,I just used one rudder in the centre. Thanks for the use of your plans
Gave the Coremorant the maiden flight yesterday ,flew like a dream. Not one bit of trim was needed. Well designed airplane. Thanks again. A lot of interested club members would like to build oneLooks fantastic! The three-blade props with the round nose prop nuts are cool as frig.
@Pieliker96 I have four questions:
Can I run this on something like a 3200 3s or 4000 3s and still work well?
Does the plane have a cargo door or a way to carry cargo
I’m worried about strength and durability, should I just go with regular flaps?
Are you going to scale it up to something like a guinea?
Really? I didn’t know this plane was so big compared to it and still ran on quad motorsThere's no reason why it couldn't carry a larger battery, though you'll likely have to move the battery tray further back in the fuselage to get it to balance proper and/or create a custom battery tray to accommodate. Of course, flight speed and performance will be reduced a little due to the increase in all-up weight.
There isn't a cargo door, though there is plenty of space in the fuselage under the wing. The extended battery tray may reduce some of that capacity, however.
Regular split flaps would work fine. For what it's worth I've found the fowlers to be surprisingly durable and easy to repair, though they take a good bit of effort over split flaps to build and get working.
I have had ideas to scale it up to a twin C-pack setup, though the main problem I've run into is prop clearance. With 6" props, the stock airframe can theoretically strike a wingtip without hitting a prop. So scaling up to a 9" prop gives a wingspan of 6.5 feet, which is rather unwieldy - the original small airframe's span is just 6" shy of the full size Guinea Pig's! Ifin I do a scaled up version it'll likely forego that prop clearance. Don't count on it though, that's one of the lowest things on my list to do currently.
The clipped servo extensions aren't strictly necessary but give you the peace of mind that they have a lesser chance of detaching themselves in flight. If you're not planning on entirely detaching the wing for transport but just moving it a tad for changing the battery, there's enough slack in the lines that you can get away without ever disconnecting them.oh and 3 more questions
are the extensions with clip necessary or can I just use normal extensions?
how are the dual rudders attached?
did you run it on 4s yet? I imagine it would be like a rocket
@Pieliker96
I think I can use the 4s, because I’m using the big ft ESCs (35a?) And using little bullet adapters from rc planetThe clipped servo extensions aren't strictly necessary but give you the peace of mind that they have a lesser chance of detaching themselves in flight. If you're not planning on entirely detaching the wing for transport but just moving it a tad for changing the battery, there's enough slack in the lines that you can get away without ever disconnecting them.
The dual rudders attach to the tips of the horizontal stabilizer. Servo arms are embedded in their foam which is linked by two long pushrods secured with zip-ties to the single rudder servo. It's a bit jank but it works well enough. You can forego the rudders and yaw entirely with differential thrust if you'd like.
I haven't put mine on 4 cells due to concerns over blowing up the FT 20A ESCs, which I'm already pushing pretty hard with the 6x4.5 bullnose props. Even on 3 cells, it is quite a rocket, by my standards at least: Easy vertical and more level flight speed than I'll ever be able to use in a small park.
I presume this means "Wing reinforcement"do think it would be necessary to have a win reinforcement?
@Pieliker96
@Pieliker96 sorry to bother you so much, but on the outer wing skin, the middle cut appears to be a cut through with a little park on the inboard side as a score. Is this correct? Also, what is the dimensions of the battery box? I want to fit a 4000 mah Lipo in.
