I disagree there. You can slap a piece of flat steel with no airfoil (think a lawn edger blade) and that will offer very little in the way of air load, but with all that weight, it will have a very slow spool up time. (and then REV to the moon on the top end, due to the light load) It's all a compromise. I typically run large diameter, wide blade, low pitch props, I don't have any airplanes that fly fast, and I tend to do mostly 3D stuff anyway, but weight is also a factor for me. In a waterfall for example, when going from idle to WOT, instantly and trying to get it "timed" correctly, if you have to "factor in" the lag of the throttle response, that maneuver is that much harder to get right. The only advantage I can see in a heavy prop, is to get a nice slow idle, and the only engine I "wanted" a heavy prop on is my Honda GX25 conversion, since it doesn't have a terrific transition anyway.

EXTREME FLIGHT

Neo, why are you sweating 15.25 lbs? That is insanely light for a plane this size! Only a few years ago planes of this size were easily over 20 lbs. You are second guessing yourself too much and spending far too much time behind the keyboeard-GO FLY THE THING!!!!!!

Run what combo works for you -of course .
Flywheel effect is another thing and basically the further out the weight is centered, the more flywheel effect will occur.
So -a light prop of larger diameter can have more flywheel effect than a heavier shorter prop -
I have found that for me the stiffer the blade -the better the performance.
On our electrics this really shows up in that the wide blades (the slow fly type) can limit performance simply due to blade wavering

LOL You're right Chris, these weights ARE insane! I'm certainly not sweating over 15.25 pounds... I'm at 15.75 pounds right now with my Pitts muffler, which still is very light, but I just wanted to figure out where some guys were saving that extra quarter pound at. I just ran in my DA with the Pitts and that thing has got to go. While I'm getting 7150 out of the DA on my Vision (stock muffler), this DA with a Bisson Pitts is only giving me 6630. That means I'm losing 500 rpms and adding about 7 ounces of weight to do it!

So, I'm ordering a stock muffler tonight and the Pitts is coming off. That will then put me down to 15.25 pounds, and I "should" be back up to 7100-7200 rpms.

As for too much time behind the keyboard... believe me I'd rather be flying. Not much you can do about it when we've had 30-40 degree weather with rain, snow and 20-40mph winds for the last 3 weeks! EVERY FREAKIN DAY!!! [:@]

This weekend is supposed to get back up in the 70's and sunshine... but, I've got a family reunion on Sunday [sm=spinnyeyes.gif]

I lived in Cincinnati in the 70's and enjoyed the friggen weather there ----
Now - we have rain here -wall to wall and still have up to 40 feet of snowpack.
So I am going flying Saturday, barring another l rain.
Back in 83 -our field went under 3 ft of water for the next 2 years -

I hear ya Dick. About 3 weeks ago it warmed up to 80 degrees for a couple days. I was in my shorts, flying my Vision, having a ball. Then, come Monday, the temp dropped 20 degrees a day until it hit the upper 20's. It has bounced between 20-40 with rain and/or snow ever since. This is only the second weekend of good weather I think we've had in 2005. It really sucks for me cause by the time I get home from work, it's usually too late to fly during the week. Weekends are about all I have... so bad weather really can rob the only days I can get to fly

I know... wah! Well, I don't think I want to fly the Yak now anyway... at least not until I get me a stock muffler!

Hello to all.

I have already the DA 50 and I expect to finish the YAK 54 in a week more. The motor delayed me almost two months, but at last is here.

On the other hand, this weekend I fly for the first time the they CARDEN CUDA and as they will be able to be imagined I am somewhat nervous, []give me good luck.

I report the fly of the CUDA[sm=tongue.gif]

The wires are coated. There is no need to do anything to them at the point where they cross.

Well guys,

After 7.5 LOOOOOOOOOONG weeks of the hardest thing I've ever had to do, I amgoing home today...it will be several months before I am back to full capacity but God's been good.

I almost died twice, lost 44 lbs (190 now) and haven't had more than a few "good days" since the first two weeks. thanks to all those who well wished and kept contact.... sorry if I missed responding, but your messages were greatly appreciated.

I'm feeling pretty well and have permission to fly as long as I wear a mask to protect from fungal infections..

My Yak (now on REAL topic) is waiting for a couple minor finishes and I'll be able to fly it for the first time...

Haven't been ab'e to wtch this thread, but I hear it's been all over the spectrum. Hope the most of you are enjoying your EF Yak as much as I know I will.

Anywho... take care and see you all more often.

Hey Maudib, I have followed this thread and it needed you back to keep it on track. Glad to hear things went well for you and best wishes on a full and quick as possible recovery. This hobby and the friends I have made in it over the years are priceless. Hope you can get back in the air soon. Craig

Maudib, good to hear you are back home. Hope you get to fly your Yak soon. I have not been able to fly for the past few weeks due to the weather. I have 10 flights on mine so far...this is my favorite plane right now. Hope to fly today.

Maudib, I am sure you got my PM...you're gonna want to do something about the header for your hyde pipe or you'll be dissapointed. I went back to the stock muffler and will keep it on until break-in is complete.

Welcome back Maudib!

On a lighter note, as Neo has told you, the weather has sucked for the past 3 weeks.

I hope to finish my Yak tonight and Maiden tomorrow afternoon if all goes well.

What Chip meant to say is that Neo had a blast flying your Yak Dave and now since you are back he really needs to get back to work on his own so he can continue having fun. One more thing, Neo did all the risky flying on yours and soon he will even try some on his!

HI all, I've been following this thread and still wounder what makes this plane so popular, is it the lightness or the accessories that come with the kit, or is it just that you have to have one to be one of the boys.
I personally set a goal for myself after buying a DA 50 that was to have the next plane I owne to be 15 lbs, I"m tired of flying a brick, then I see this thread of a 3D plane, guess what, 15 lbs, I"m almost sold on getting one.
