Dissimilar formation is tough enough from inside the plane and prop to jet even tougher. Well done.

[@KB_RC]

Definitely a challenge. Thanks Mike!

[@rlbutterfield]

Nice effort, guys. Formation is tough! 👍🏻🙂 Matched planes would make it easier.

Thanks Randy! Just a couple videos away from that 😉

Be very careful with cosair on 8s. I did the same to mine. Blew the hub and that's an understatement. It BLEW UP. I re did the whole prop assembly and it took a minute but the whole prop assembly i re did in aluminum. What is didnt change were the props and that was my downfall. The props literally ripped out of hub. I should have gone for a kevlar/carbon fiber composite. Other than that it was amazing i flew it that way for about 4 months with about 3 dozen flights.

If i could load pics i would show you the hub. But like i said it literally blew up and the front quarter of the plane went another 200ft down the runway. I was doing a high speed pass and it blew pretty much in front of me about 20ft away. The front quarter took with it both batteries and the receiver while i watched the rest of the fuse just quite literally flutter like a leaf down to the ground....😅...yea i was laughing when it happened. But man i really loved that plane and they discontinued it 😢. Anyway like you're guys vids and its nice to see young people in the hobby.

[@KB_RC]

Holy crap! Thank you! Actually not the first time I’ve heard about that happening. I’ll take a look and upgrade the prop before spring. Thank you very much!

@KB_RC All I did was put a Hobbyking 120amp esc and programmed it to high. I ran the numbers and rolled the dice because I thought the stock props were thick enough (WRONG). The problem is that at higher rpm, the props start to oscillate (wave). So you need a stiffer prop and just a little less aggressive pitch. 18x10 or 18x9. Good luck and safe flying.
