wing underside for barry

Thanks. That really looks good. Should be easy to see. I can't wait. Mine should be here on Friday.
Thanks,
Barry

Thats a BIG freakn aileron, I like it. I was told today that mine has shipped and should be here friday.

what would be a good 2-stroke alternative for extreme 3D?

OS108. That would work good.
thanks,
Barry

so far she is BREEZING together and i am seeing nothing but quality way better than F90. it is also pretty good size for what you might think a 68" plane would be . the elevators are amazing!! to say the least and an ultimate sized rudder compared to plane..

Gonna pick mine up friday afternoon, have it the air monday morning. Wife is working the weekend so nobody to stop me!!!!![:

yea wife called me off after 2 hours.. but that is the progress i made in that time.. the last 2 planes i did i would have rather gone back to kit building. but this one is going smooth so far. i did see some areas where i needed to CA in the fuse area. when you open the canopy your like WOW. there is some nice lazer cuting in there and it is OPEN . i was contemplating puting my tank over the cg but the only thing in the fuse that blocks anything is the wing tube and it is smack dab in the way. if you put it behind the tube you will run into the same problem as the F90. as it runs out of fuel it will gain nose weight . so im just going to but the back of the tank against the front of the tube. I am also going to wait and balance it to see weither im going pull pull or in the tail rudder servo. I bet mike has run his with a YS-110 on the prototype he can tell me before i get there,HE HE.. I see he is contributing to this thread

What about an ST2300 with a pitts muffler?

your approahing YS-110 cash there. unless you are getting it used..

DA 50 if you really want to over-power it right.

I don't know why wives won't leave us alone to build our new kits, when we are in the house they ask us why we don't go to the shop and get out of thier hair, and when we are in the shop all weekend they accuse us of not paying them any attention.-----oh well.

I only have a good running saito 1.00 to put on mine. it is more than ample with a 16 x4 using 30% omega on an 8 pound Harrier 3d. Hopefuly won't get too much heavier than that so the performance will be adequate. Had a 1.50 in an Funtana 90, that worked out well but parted company with the airframe and engine so the 1.00 gets the nod. Will know one way or the other in a few days.

Thats true for the OS that its comin close to YS110 price

I checked the specs and the:

OS 108 is ///// ST2300
26.5oz ///// 38.0oz. w/muffler 31oz. w/o muffler, not sure how heavy the pitts is
3.0bhp at 16,000rpms ///// 3.7bhp at 12,600rpms
$269.99 ///// $149.99

I have not tried the TS 110 in it, but I do plan to after the NATS if I get a chance. I'm sure it will be excellent in it.

at $269 IMO you could save the extra and get the $335 and get the 110 and IMO be alot happier with the power to weight performance. I know you are itching to get something going but i have been there before it is better to hold out and save to get what you want and not what you can get by with. you will be happier in the long run..

darn i was hoping you could tell me in advanceon the CG with rudder servo placement

I guess your right! I'm trying to go the cheap way since I don't have a job yet(i'm 15)so you know money doesn't really come easy. But i'm going to go and apply at a few more places and hope someone calls me.

I believe the YS110 weighs more than the Saito 100. With the Saito, I have the rudder servo in the tail, and a 2700mA NiMh rx battery pack under the fuel tank to get the cg I want (which is not tail heavy)

What about servos? I checked horizons recommended servos but they are WAY to expensive at $100 a pop.

ok so im thinking i will be at simmilar because i am running a Lipo for a battery that will make up for the weight difference in the motors.. but i will still check it due to differences in one plane to the other befor i cut the opening in the tail

the 645MG would be bare minumum wich is what im using,, at 6v i have also skimped on servos and have had some almost catastrophic falures.. if i had the cash i would go with the 5645 digitals

I would stay with metal geared servos. The control surfaces are very large and were running a lot of throw. I like the JR 9411 on elev and ail and the 8411SA on rudder. Lightweight choices with great strength and precision.
You certainly dont need those servos, but its not a model suitable for standard sport servos either.

Mike I saw on horizons site that those servos that you listed are, Torque: 82 oz/in and the hitec HS-625MG are, Torque 4.8/6.0v : 76 / 94 oz.

The only engine that I would consider with this plane is a YS110 swingin a 16x6" APC.
