That is all the more reason to go with the Yak 55. Buy some foam and a couple tools and start cutting. Build it as you can afford little by little and you will have a great flying airframe.

I tried my Sukhoi with two 330 3S packs in parallel (normally fly the YAK with one 330 3s pack). 328+ grams. It's no floater at that weight but it flies surprisingly tight and pretty loops. I was shocked when I saw it. I think the combination of more propwash over the elevator and the increased weight of the plane makes it want to stay in place and rotate around the CoG.

Hey Rick,

That should make you feel better about your 230g "lead sled". I told you it was flying fine before you went all medieval on it trying to lighten it up. Just go fly!

Hey guys, on the 36" Yak . What size spar for the wing ?

It was 227g on the day of its maiden and the first time you flew it in Auburn it weighed 213g. Last week I was able to shave it down to 202g and im still hoping for more this week with some strategic milling if i have the time. I added some colored shrink tubing in case any of my parts fall off so it wont be like "Honey I shrunk the Aileron Linkage" again. I'll bet thats a mistake many pilots make on there first indoor plane regarding the weight. The last time I flew before the Yak was with the KOMBAT 40 stump puller back in the day, weighing in around five pounds and if you strapped on a pipe it seemed to break free of earths gravity!

I understand the definition of a planes "AUW" and what it means but does that weight people give for comparison without the battery include the RX and the ESC?

I'm setting the Sukhoi up for wind flying. I wouldn't mind if my YAK were lighter for still air flying.

Well, the 6mm kit I make runs about 40g lighter (141g) without doing anything special. There are options.

42" Byper? You should fly mine - flies very different than any of my other planes.

AUW is the total weight. Sometimes people will say AUW minus battery since the battery size can be changed. Often they will say auw including an xxx mAh 2s battery so you know how much weight the battery accounts for. You would normally include the esc, Rx, and all other components when quoting an auw.

Yeah, there is a red one in my future

Sure but I'm starting to have planes like Kirk has Tribbles.

Yeah, I have a prototype graveyard that is scary. I try not to let the family in the shop to see it. And I just can't crush them all up. Lots of times I will resurrect one to try something on

I seem to have the same issue. I used to know how many planes and kits I had... now I am afraid to count them all.

Yeah, it's sad. And then there is the issue of actually repairing and getting out to fly. By scheduling the 4 hour indoor session I actually HAVE to take the time to go fly which helps. And I go near the pile to scavenge something and all I hear is Johnny 5 saying "Do not disassemble"

My legacy to my kids will be selling off the NIB kits I seem to have accumulated over the 40+ years that never found building board space

My best guess is a 4mm carbon tube would be a good choice.
