Finally finished the big grunjet! Balanced perfectly with a 4s 3300 in the nose. Weighs about 2.75 pounds at the moment. Hoping it flies nice!

Okay, Just to prove I really have 2 of them. Actually a 3rd on on the way, started it tonight. I really need a conventional tail version don't I? Amazing how fast these go together and how well they fly. I've gone Grunjet crazy!

Love it!!!!

 

[OliverW]

Love it!!!!

I loved it for the 3 minutes it lasted 😆 it had a super low wing loading. I dropped it when tossing it and it just bounced off the ground, and then started climbing on a 45° upline! My plywood reinforcements weren't strong enough for the wrath of a split s though

Oh no! Looks like your EDF is fine. Only real damage is foam board. Take what you learned and try again.

Definitely gonna do so! Just gotta find time

Yep Squirrel, Time is always the problem isn't it. Another reason I like this airplane. I can set down and in just one evening get a lot done. 3 evenings just about builds a complete jet.

Hey guys,

I'm in the middle of building my first grunjet, (Just got my first EDF for Xmas!) and I can't decide between V-tail and normal. Anyone have a preference from what they've flown?

I like the v tail a bit better because it has rudder control and because I feel that it looks better
