If the lead ever drops out-She'll come down like a sac o' spuds. Now the engine has to be perfectly tuned for him to get any usable power in the vert. "Its a bit slow in the uplines" would be a under-statement. The poor ol' Da is humping a serious lunker around with all the extra lead. Ive got nicads on rx and 3cell lipo on ignition with a MVVS 58 upfront with no need for extra lead to sort the CG. The power is great Beware of the lightweight must-haves? Might leave ya chasing yer tail

Had a good look at my mate inkys 88" at the weekend and managed to sort his overweight problems. It all started to go wrong for him when he made a 8th ply plate to mount the regulators and battries on, He positioned it 12" behind the cg and combined with the weight of the pilot n cockpit made it way behind the recomended rearward cg point. Tail heavy as tats he put 2 lbs of lead on the nose and made it sit on the rearward cg mark. The all up weight must of been 19.5 lbs maybe even 20lbs plus. At least it was a insight of what the wing loading on the 88" would be if one was to install a DA85. (Madness)-Wing-rock delux in the upright harrier Anyway i persuaded inky to ripp out that chunky ply plate n make a smaller one right up front. Moving the battries n regulators as far forward as poss'. All the lead is now off the nose and the cg is on the rearward point. Saving 2-lbs off the all up weight has made a big big difference. Just shows how a rushed installation will get ya into nothing but nighmares. Looking forward to seeing him enjoy the plane as it was ment to fly.

Top tip mate. I strengthened the rudder supports and flat spins are loads easier. Its amazing how a tiny bit of movement on the rudder mounting makes things trickyer. Thanks for the heads up buddie

Sorry about the long update. i havnt had a lot of time for pics. But anyway here some pics. the plane is almost RTF, I'm waiting on the batteries, switches, regulators, and all i have to do is mount the reciver. pretty much finished. this plane was definitly really easy to build! The hardware that is included is amazing!
i made an removable tray for the reciver, reciver battery, and regulator. All servos are mounted in. Hitec 5955's all around. DA 50 with the DA 50 muffler, Mej. 23X8 prop, and Petes 4" carbon fiber spinner. I got some graphics on the plane as well.

Looks great Tony!

I had started to do that with the checkers on the 74" I was building but decided not to do it. KICKING MYSELF IN THE TEETH NOW!!!

Tony maidened the Extreme flight 88" Yak today. I'm posting some of the pic's I took today. Tony will be posting some video later. All I can say about this Yak is "WOW". It presents well and is the best flying 30% Yak I've seen to date. It's a keeper. Now if I could just fly like Tony..... .

[TonyThomasian]

Hi everyone.
The maiden was great! The 88" Exreme-Flight Yak 54 is definitly the best 30%er ive flown. It has NO bad characteristics like all the other 30%ers ive flow. a lot of them tend to be "snappy." This Yak has none of that! It is very controllable and smooth. it fly's precision and 3D like crazy! The rolls are very axail, which makes the rolling harriers really easy to do! It hovers really stable and under control. Rolling harriers are super smooth and easy to do with this plane. It fly's SUPER light and weighs really light. i will get the exact weight soon. The CG was pretty much neutral, but just a tad tail heavy.
I have a video here that has flights from my 2nd and 3rd flight. And i also have some pics of the completled plane. i will upload them later tonight.

This plane is amazing. The ARF/hardware is awsome. The building is very easy and quick.

Skyman,

Welcome to FG!!!

I believe that Extreme Flight has the 88" in stock again. I seriously doubt that you will find one used. At least for a while.

As far as your Edge, why don't you start a new thread about it. I'm sure with all teh experience on this site, someone will be able to tell you exactly what to do.
