Michael Dilger : Please Cut up a lipo

Low Elevation RC : "I've always wondered, can you actually hotglue a watermelon to something?" Uhh... Yeah, I've "always wondered" that too

Karl-Emil Storm : I love your consistent uploads, hahahaha. This is so good! Greetings from Denmark!

Robert Kitchen : David I would like to see the rocket knife cutting through a DJI phantom 1, whilst hovering.

Ben Carter : That energy absorption at the end needs to be more progressive. It is always going to cut through a blanket if it is cable tied to the frame. I think it could do with 2 or more frames behind each other. The first one would catch the knife and then go with it, so attached to bungees or cables that are weighted. Then that would hit a second more rigid netted frame. Slow the deceleration down like they do at Circuses or those free fall rides which have double catch nets.

Airborne Images : Try slicing a water balloon. The high speed should be great.

Christopher Raff : Deer: I'm going to get the hell out of here; that guy has a knife with a rocket attached to it! No way this ends well for me.

Daniel Tomas Jr. : Put a mattress on a cord, lead. When the rocket hits, the mattress moves but is connected to the cord. It will slow it down. The easier the better. The physics are there.

HorrifiedPilot : Cut a rocket knife with a rocket knife.

Quinten Moonen : Rocket knife vs wild deer?

Detour FPV : This is why I buy from rcexplorer. David's madness needs funding.

AeroGeek16 : Cut carbon fiber with the rocket knife!

ABSnyder RC : These videos are awesome David! Keep up that crazy Swede stuff! Oooo shiney!! Real nice!

BLeeKiis Too : Every time I watch another episode of Rocket-Knife I think of yet more things I wanna see it take on! This time, I'd like to request a motorcycle helmet- WITH a ballistics gel head inside it... 3:) Thank you again :)

Jonesy Films : Nice David, adjoneses here, I think we all just found the solution to the North Korea threat

John Possum : How about cutting a 5# gummy bear in half?

LowLightVideos : RocketBike 🚀🚴

Hakalabakala : 100% sure it isn't copied from the backyard scientist

231ian1 : 2:30

Luisangel Corona : nice work!! I think it"ll cut 5-10 watermelons easy!! maybe a pineapple next?

ArthurDent0042 : It seems like your engine was burning longer on this run. In your first (successful) full-charge test (Rocket Knife - It's working! But how fast is it?), it seemed as if the fuel had burned out before reaching the end if the rail. On this video, it looked like it was still burning as it passed the watermelon. Have you changed your fuel in some way from your first full-charge test?
