This is my first delta wing jet that I ended up building without plans. I'm a newbie to this hobby and I've flown mainly top-wing like airplanes and some RCPOWERS jets...
This one is about 760mm span and about 840mm long, about 600grams with 2200mAh..when I first built it it didn't have a KF foil or fuselage walls doubled ( due to rough landings and it's made out of dollar tree foam.) Originally it was Power by turingly 2200kv Motor but I replaced it with 2700kv when I added the KF foil and fuselage walls. Added some weight and since the whole model is hot-glued I thought it wouldn't hurt to add more power.
My question is, what's the best way to slow the plane down to land? Do flaps work well on a airplane like this or a different type of air-brake?
I hope the pictures uploaded fine...

No Pic's I'm afraid.. However your Build sound's good!! the 2200kv was prob OK however you didn't list any real Details, IE: weight of Loaded Model, type of ESC, Battery type, servo usage, CoG details, kind of control surface's used, linkages etc. More over TAIL TYPE...
If you are using a V Tail set up, this is best for AIRBRAKES, flaps are at best JUST ok.. but the V-tail is best for that, cause it doesn't pitch the plane forward causing you to use more up elevator, like flap's will do to you...
Spoilerons and V-tail are the most beneficial as in this manner.
So using Spoilerons and V-tail Airbrakes pitches the nose up, slow's it down to a crawl and gently set's it down with ease, onto Terra firma.. IMO

Happy Contrails to all!!!

Heavy planes land heavy. I fly till I feel a loss of power from the battery. Then I cut the power, glide down, and land. If you do a stall with no power as it gets close to the ground, it slows down quickly; for a soft landing, timing is important. Add airbrakes, and it slows down even faster.

The all-in weight is about 600 grams. I use elevons and rudder, two metal gear servos and a 9 gram servo for the rudder. ESC is a 50 Amp birdie, nothing special but does the job. I uploaded a pic, hope this time it actually works.

Nice Plane, airbrakes would be tough with that one, any Ideas Luke??

Two ideas:
1) Fly where there is some deep grass around to land in.
2) If you still want an airbreak, spit the tail and add a servo.

Thank you guys, Luke I actually only flew it in area with tall grass. I think the dollar tree foam is just too weak to handle rougher landings, however I won't spend much time modifying this one since it's my first delta type. The idea was just to see if I can pull it off, building one without plans and getting used to airplane that is much faster than what I'm used to.
