EF Yaks are coming...who wants one?

[gyro]

As long as they are Yak 54's and not 55's (ugly ass airframe imho), I'm in for a 48". 91" is too big for me, a 70-74" would be nice.

48" will be on the next container I believe. We will definitely be getting one for a site review!

its interesting, for some reason extreme flight is staying mostly away from the 70" range planes, they seem to be gravitating around that size (48in, 60in, 90in). i wonder why

 

[gyro]

Yeah, but they are adding the 78" MXS soon

oh yeah, forgot about that. as far as gas goes its great, but for electrics its kinda an awkward size, i think its a little much to fly on a single pack (6s5000). I wish they would post videos/more pictures of planes that are soon to come out. i need plenty of pictures and videos and have time to make up my mind before it comes out!

The motrolfly 4330 might be a good motor for that plane... Maybe on a pair of 4s4000 or 5000 packs or something like that?

yeah i was just looking up light setups, and it seems that people (including donatas) have done a 6s5000 setup on the 78 extra and gotten it down to around 10.5 lbs (apparently donatas flew the 78 extra in a competition that required <11 lbs, and he got it there). Thats really promising, and something like a hacker a60-6xs with a 22x10 would be a KILLER setup on it, but it makes me nervous about balancing. I dont know how easy it would be to join the elevators, or to do a pull-pull elevator, just to get the CG right. may be more of a pain than it is worth

Pull-Pull isn't that hard when the plane is designed for it with a double control arm on the rudder, and the tray under the canopy... I've never tried building or adding it to a plane that didn't have those incorporated into the design.

yeah im talking pull pull elevator AND rudder. there is a sebart plane (the sukhoi 3D monster) that has it, and it looks crazy complicated. but the video i found of the ultra light 78 extra looks pretty great

Yup, I missed that... Definitely looks challenging!

All you need to know about pull systems is "if it centers leave it alone."
