I did this mod before even flying my ultimate for the first time. It can also be done without cutting any foam. Just remove the cowl and with a long screwdriver dislodge the weights from the fuse, then pull them out of the slots next to the battery tray, they fit through mine perfectly.

Hey I'm late to the party here but THANK YOU!! I've been looking for those damn weights and you made it easy brother! I sure appreciate it!

You made it seems easy

Just flew mine yesterday, finally got it trimmed right and cg way better than ever , flew good even in to much wind …..haven’t removed weight yet

My FMS Pitts also had TWO big weights in the nose. Found them after it crashed due to a ESC failure. They look the same.

Great video! Thanks to you, I did this mod a while back and I think it's a huge improvement, even for a less aggressive flyer like myself. Before the plane would sink when not under power and now it feels a lot "floatier". Any idea why HH felt they needed to add so much "permanent" nose weight instead of giving the user the option?

@TwoBrosRC

Жыл бұрын

We don't speak for HH, but one would reasonably conclude that the nose weight was added to ensure that newer pilots wouldn't accidentally fly a tail heavy airplane. Seems like a solid business decision, but we don't have any info aside from speculation. Either way, it's fortunate that you can easily mod the model to remove the weights.

Great video, I had some questions but they are nearly all answerd in the reactions. I like to thank the Two Brothers and al the people in this video and reactions. I know this is about 3d flying but I like also flying low and slow , is removing the weight for and aft beneficial for slow flight?, I just saved 88,4 gram = 3,12 oz , now I can fly one mile futher on a 4s batt. :-)))

Slow flight is definitely improved by reducing wing loading and getting the overall aircraft weight down.

Do you use the metal stabilizer spar or the carbon spar for the right CG?
