not good if you want it to be sub 250....
what aircraft under 250g would do better when there is a breeze?

the TT listing says it's 248g with battery, so I'm gonna guess it's the lil bits of glue and such that may tip it over.

what does it weigh with the prop?
you mean flip the motor to the rear? have you ever thought about modifying it with an EDF?

maybe for the 3 channel wing it hits that stock, I had to strip a whole bunch of paper/etc to get the 4 channel wing under 250g w/ battery.the TT listing says it's 248g with battery, so I'm gonna guess it's the lil bits of glue and such that may tip it over.
note -> the 4 channel wing has 2 5g servers that the 3 channel wing doesn't have and IIRC there is a bit more foam in the wing also.

EDFs are for "go fast, battery dead as fast as you can blink" planes, also not something I would recommend as a "learn to fly" plane as they generally have some flight characteristics that aren't as friendly as a prop plane (IE prop planes "blow" over the control surfaces, which can give you control at low speeds, EDFs normally don't have this, so if your speed gets to low, you have way less control).what does it weigh with the prop?

The FT Dart is a twin motor flying wing. The motors are mounted in front of the wing. The stock version has the motor pods below the wing. I have 3D printed pods that put them in line with the wing.
Single Tractor configuration would be to mount a single motor in the center/front.
Single pusher would be to mount a single motor in the center rear.
Dual motor setup uses 2x 1106 5000kv motors.
For single, I would probably use a 1406 4000kv motor.
Part of me wants to throw a flight controller in one and configure it as a tailsitter. With the motors blowing over the center of the wing, the elevons should have enough control authority. I was able to take off vertically with little or no toss with the motors, props, and battery combination that I had with my original FT kit version. Need to do finishing touches on this and weigh it. The black foamboard may be a little heavier.

how do you differentiate the 3 channel vs 4 channel wing Tiny Trainer model? also, I think I mixed up the Tiny Trainer with the Tiny Tutor...the TT says it's 198g w/o battery but the TT says it's 248g with battery. I bet taking the landing gear off would give more of a buffer too.

aaah...I was mixing up Delta with Dart. The Delta is single puller.

well...I was doing some reading and saw a requirement for you to have a Basic Pilots License to fly anything over 250g+ to 25kg at an approved MAAC airfield or that you must Advanced Pilots License if you want to fly anything 250g+ within an exclusion zone surrounding an airport, helipad, aerodrome, etc.. our airfield is within an exclusion zone and when digging a bit more found that even if we had the appropriate licenses, our airfield is approved only for sub-250g drones, nothing heavier can be flown...so BLAH! the next closest airfield is like a 4 hour drive from here.
Three channel wing has no ailerons. Controls are Motor, Elevator, Rudder. (upper wing in pic)
Four channel wing add ailerons. It is also a flat wing (lower wing in pic)
With a 800mah 3S battery and the 4ch wing, mine comes in just under 300g. Mind you, no effort was made to lighten this build, it has a TON of rebuild glue in it, and some reinforcements, and my buddy's daughter that built it FliteFest 2016 put a bunch of stickers on it. This thing has been through a LOT of abuse. Its roughly 275g with a 450mah 3S battery. Should not be hard to build one sub 250.
I have not flown it with the 4ch wing. It is ready to go next time out to the field.
You should be able to see the clear packing tape I use on the leading edge of the flat wing.

the 3 channel wing had polyhedral and no ailerons, the 4 channel wing has very slight dihedral and ailerons.

no, because if you scale the images, you also scale the folds/etc but your foam doesn't get thinner to account. if you understand how the construction works, you could likely get away with scaling it manually or adjusting the A/B fold areas to account for that.
