Weight problem (ft tiny trainer)

#1
Hello, I have a small question, how much does your tiny trainer weigh?, Mine weighs 375 without battery, will it be a lot? Sorry for the misspellings, I speak Spanish

Mine is around 340g all up with battery, it was built from a speedbuild kit.
I suspect you made yours from white EU foamboard, which is 40% heavier than FT board. This will make it a bit tail heavy as well. You might have to mess about with motor sizing and run a 3s 850mah battery to get the CG right.
If you find it’s a fast flyer then add some incidence to the wing, I put sticky Velcro under the leading edge of the wing, it lifts it up and this increases the angle of attack, which increases lift at low speeds.
