Like when I put my Radjet into too steep of a dive....
Believe it or not, I am having massive issues with the parsing of this statement. Something has got to be wrong here that I am missing or all my experiences never got this far. Death dives from couple hundred foot up, did that. Oopsie dives up about 50 ft ending in a bag of balsa, check, did that. Talking to someone ending in a balsa bag, did that.

Ah, My spar didn’t extend into the wingtips…

Maybe you were too close to the ground. There is nothing wrong with going straight down as long as you have room to pull out......
Unless that dive lets you go over the structural limits of your plane... I personally really like the big vertical maneuvers when I'm flying (loop, Cuban 8, split S, dive, etc.) but especially on some cheap foam planes I've had unexpected departures of flying surfaces from my planes when I did power dives and I had a foam board plane years ago where one of the control surfaces fluttered enough it broke the servo.

But agreed, generally dives aren't anything to be scared of

My Strix Nano Goblin #1 (may it rest in pieces) used to do full power dives really nicely up until the control horns on the elevons worked loose. LOL.....

Yeah, that's why I use 17g metal gear servos in my speed planes....Though once when I was doing a pull out of a dive one of the vertical stabs on my radjet ripped off!..Not sure how that happened... :unsure: I am guessing it wasn't perfectly in line with the plane so it was getting some flutter and it just worked loose..

Yup, it was a VERY high G pull out.

Where are you breaking the wing? Typically for me, it is either where the spar isn't, or the spar is joined, aka: weak spots. When I do cartwheels on landings, it will break where it wants to along with shedding tail feathers, crunching fuselage.......
