So Dick Hanson, will we be seeing a review of the Showtime in 3D Flyer Magazine in a couple of months???

very likely---

Quick question,

Just about to install my engine but it really needs to be side mounted. Moki's don't like to be inverted.
Is it just a case of mounting the T beams horizontally using the original holes instead of vertically?

I think it is but thought i'd check first

Thanks
Simon

You have to drill new holes a quarter inch up to make it line up.

Thanks,
I presume you mean to line up with the cowl?

Simon

Yes

yea the YS-110 is plenty of power for it.. i guess it all depends on your altitude. im at 960 FT according to GPS at my field

Tianci, if you want to swap the extra for the showtime, talk to wee, he may go for it.

I agree about the gaps in the wood joints, which is why mine gets the full treatment with wood/white glue and polyurethane glue where i can reach. But I also like the fact that most of the major glue joints ariound the firewall area look to be epoxy instead of that hot melt rubbish.

Same question again, anyone had problems with the screws that go through the control surfaces coming loose, or the wood cracking?? am thinking of either putting in polyurethane glue or epoxy then tightening the screw up.

WOW!!! thats what i thought after flying this plane. I have a ?, how big of a difference do the sfg's make? I flew with them but if they dont make a big difference i wont use them. i dont think they will last that long.
BUY THIS PLANE

Question regarding SHowtime set up.
1. Do Hitec 5625/5645 servos come with arms long enough to get the Showtime's required throws? I know the come with alumimum arms, but how long are they??
Thanks!!!

It doesnt come with any arms. I am not sure what size we used but i know there not stock.

Seems like there should be an aluminum arm????

Per the Chief Aircraft descripton for 5625's: The powerful HS-5625MG is perfect for those high demand applications requiring a standard sized servo. With a custom designed programmable digital circuit and Hitec's unique Alumite/MP gear train technology, the powerful and fast HS-5625MG is perfect for those applications that demand a high speed servo.

Also includes an anodized aluminum servo arm And then they show the picture as below.
Specifications:
Part # HS-5625MG

the aluminum one is not long enough .. use the black one that comes with them. it will get recommended and some if desired.

I thought you ment that the plane came with arms. My bad

Question for you guys experienced with the uniflow setup.

If I set up my plumbing with the uniflow like shown in FlyRC, will I be able to keep the tank closer to the CG (just in front of the wing tube).

Thanks

I flew mine today and it was way tail heavy, a real Snapasaurus. I couldnt do squat with it. It has the worst wing rock and is not stable at all. It did a great blender and nice flat spin but I almost crashed pulling out as it wanted to snap out, even KE was a chore. The thing that gets me is I set it up (I thought) a little nose heavy. I thought it was suposed to fly like a Foamy, it did not.

I moved the battery under the wing tube and will fly it again tomorrow. What really hurts, is I left my little YAK at home thinking this plane was going to rock, well it did, side to side like a drunken sailor in the Philipines. I could not slow it down in a harrier or it would snap over. I wish I had a good report but I dont. I set the CG at 7 6/16" and all the throw I could get. I was using 60% expo on the elevator and it was just a bear to try anything but straight and level flight at moderate speed. I tried a wall and almost snapped it into the ground. I can say one thing for the plane it is responsive. The YS 1.20 has plenty of power it pulled out of a hover, not like a rocket more like the space shuttle. 8.5 lbs would have been much better.

I fly my other planes from take off to landing on high rates, I never change. I harrier land my foamy and my Mayhem. Are any of you guys flying the ST the same way or is it too unstable or was mine just way too tail heavy? My H-9 Edge is the same way and it just sucked, too tail heavy and a snapping dog on H-9's recommended CG. I dont want to bag on this plane too much more since I know it was tail heavy, but come on I set the CG as instructed, a lesser pilot would have plowed it in. It was a good thing I was on the dry lake as I could land in any direction and I just let it settle on its own and land. It did pop up pretty good when I applied a little elevator to flare before touchdown-made for a fun landing.

First impression:

Does not fly like a foamy, is not as stable as the Mayhem, the recommended CG is not working on my ST, no fun to fly in this condition.

I got 2 test flights in on mine today, at the reccomended CG I don't think I have flown a better flying plane.
The saito 100 is new and still rich but it had enough power to hover but not pull out.

Were you on high rates and 3-D'ing or flying big cirles, do you fly on high rates all the time or switch? I'm glad it is working for you, were you going to answere any of my questions or just tell me that its the best plane you have ever flown?

I am watching Kyles video as I type and I must have screwed the pooch when I set the CG, I dont know what I did wrong but my plane is not stable at slow speed or with too much elevator. I dont measure throw any more I get all I can get on my planes. Oh well I'll just have to play with it untill I get it set up right, they cant all be perfect out the gate like my little YAK. Oh...... that sweet little electric YAK One more thing, Adam your video rocks too, the plane looks solid and stable in your video-good job.

Big Barry, My CG is right on the money and the thing flys & lands like a baby. Nobody else on this thread has had any real CG complaints. From your description, it does sound tail heavy. I would suggest that you recheck your measurements...You know...measure twice, cut once....
Are you checking it at the fuse? Something sounds fishy.

Here's what I do if I can't use a balancer. At the root, from the leading edge, measure (twice) and mark the CG on the root rib. Draw a line square to the rib, and then transfer the mark to the wing surfaces. About 1/4" to 3/8" from the root, apply a very small drop of epoxy. After it fully cures, install the wing and "feel" for the "dots" and lift.

I put the dots on the bottom only, and did not balance this plane upside down...

Good Luck, I hope you find the cause.

And More....

Because you are on high rates all the time, at slow speeds the plane/surfaces are probably stalling...as opposed to snapping.?. Maybe up your expo or go to low rates and see what happens.

I was thinking the same, but I fly my other planes like that and they are stable at all speeds. I am going to recheck the CG and all flight surfaces again to make sure something else isnt happening as well. It flys exactly like the H-9 Edge did so I think it is the CG. We shall see- time tells all.

I find the same also with my Extra 260. I can take off with my Mayhem with full rates, but the Extra was too twitchy, and just for your information, I toned down the elevator and ailerons to 45-50% while high rate was at 140%. That's how much I really need to bring it down. Moreover, I had to increase my expo even at low rate to 40% to get the feel I want. At high rates, my Extra would stall bad everytime I pull on the elevator too hard without enough airspeed. And if I have even a hint of aileron input, it'll snap. I used to keep my stick tension low so that I can hover better, but now, I find that keeping my stick tension pretty hard keeps me flying smooth.

HTH

Josh

btw, do you guys keep your tank at the stock location or move it near the CG?

My tank is in the stock location, and I needed 6.2 oz in the nose.

what motor?
