Showtime 4d *.90*

[JohnnyKatana]

looking to get some pics up within the next couple of days
Hacker a60
2x TP 5S3P 6000mah bateries
master 70 esc
should come out at about 11-12 lbs

power system alone cost 1400$
yikes!
glad i have a dad with as big of a love for the hobby as i
and an even bigger paycheck thankfully

i dont know how he has the patients to build all my planes
thank god hes a mechanic, bonus! haha

That's pretty heavy for that plane. Be careful not to stall the wing. I have an O.S. 1.60 in mine, and because of that it weighs 10 lbs. It is very snappy. It's not even fun to fly at that weight. I don't mean to knock the wind out of you sails. Just be careful when you fly it.

we have one with a saito 100 and it comes out at around 10.5 pounds just because of all the repairs
we fly w/o the sfg's and ive never had to much of a problem with it
the only thing is if you pull to much elevater in a turn it likes to snap out reeeal fast

EXACTLEY.

I had a saito 120 in mine and i wrecked it because i stalled it and it spun. I was low and hot doggin' a little more than usual. I loved it for precision and even with it being kinda heavy i did tail touches and rolling harriers right on the deck. its main problem is that you cant pop it up into a wall because it drops a wing and goes knife edge.

I have one here my setup:

Axi 5330/18
Jeti 90 amp
JR DS8411
JR 770S
JR 9303
Tanic 10s1p 2480 pack
Apc 18 X 12

I am pulling around 65 amps.

My showtime is a plane that I only use for demos. Its to demo that anything can be flown as a electric and it can peform at the same level as a gas plane could.

[JohnnyKatana]

is 2480 mah enough for a long flight
were going with the hacker recomendation
which is the tp 6000mah
we had the new exteem series or w/e it is
and they weighd something like 4lbs

what is the difference btween the extreem and original series
someone told me 30c discharge
but wouldnt 20c be enough?
doesnt seem worth the weight to me

does anyone by chance knoe\w what mark leseberg jr. was running in his at the AZ electric festival in mesa a year or two ago?

10S3P TP's is a big pack for that plane, 10S 3700's or 3300's might be more suitable.

10 Pound plane @ 200W/lb (good starter for 3D) = 2kW, which is within both of those packs limits.

To get 2kW from a 10S pack you only need about 60A, so that is 18C for the 3300's or 16C for the 3700's

I had a showtime with an OS 160. My club clocked it at 99 miles per hour. I eventually scraped it because of the bad flight tendacies. I beleive these tendancies are built into the plane. They tend to increase as the wing loading increases.

The rudder is too small far the P-factor, which comes into play at slow airspeeds, and high angles of attack. If the plane fall to the left in a torque role, it does not have enough right rudder to center. The fuselage does not have enough right trust built into it to conteract the left turning tendacy.

You will notice that you will need substantial right aileron trim to maintain straight and level. This aileron trim at high airspeeds will cause adverse yaw at slow airspeeds, because of the increase throw needed at slow airspeeds.

Torque rolls to the left will be nice, but to the right nearly impossible.

Your power setup should be interesting to see. Only I think that it would be better suited for another plane. However, If you are satisfied with the outcome, that is all that matters.

well ive had my other showtime for about a year
i have noticed it likes to fall out to the left in hover
but we took a chunk out of the inside of each elevator and lengthened the hinges on the rudder and i now have about 75 degrees of throw in the rudder
we had to switch to a digital servo because of this
we also used some balsa to correct the thrust problem so now its about spot on
and in reality, i love how it flies without the sfg's
i can feel so much more drag when theyre on
and have u ever tried landing in a crosswind with those things?
i have
it results in the landing gear going bye-bye and breaking a 16 dollar prop

I don't think there is anything wrong with the design of the plane, you just can't build it heavy. This is no different than any other plane. My Showtime torque rolls just fine. I don't need any aileron trim to make it fly right. The rudder is just fine on this plane. I'm not to sure what you guys are talking about. Mine fly's great, other than the high wing loading. My plane weighs 10lbs, and that is my fault, because I chose to install an O.S. 1.60 in the plane.

When you land in a cross wind, you need to straighten the plane out before the wheels make contact with the ground. SFG's or not, cross wind landings are done the same way.
