It's actually a Top-Flite Power Point:
http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXHY46&P=0

I do have a couple of Xoars as well, but I figured I'd start with the Top-Flites since I had them just in case of any landing mishaps. The thing flies so nice, I'm not sure that's gonna happen though. Even in a 20mph wind today I didn't experience any real surprises. I was a little apprehensious about landing in that kind of wind, but didn't really have any problems. It does tend to float a little, so I'd watch out for that.

Edit: Haven't weighed it yet.

chris8105, while I wouldn't call it slow, it's definately no speed demon. You have to remember that the bigger planes tend to do everything slower. I've been flying a Mini Ultra Stick (36" span) up till now and compared to the Sportster, it looks like a pylon racer. The Sportster is what I would call a docile aerobatic plane. It's not meant for 3D but could probably do just about any IMAA-type manuver in the right hands.

As far as the stab failure earlier, yes it's been a known problem on the Sportster, but as the posts about that earlier in the thread say, it can be avoided by sealing the hinge gap and adding a couple of support struts or flying wires. I haven't seen any such behavior, but I haven't been doing any high-speed down-line runs, either.

Status: offline 		G2300 would be a bit small I believe. I have the 3250 on mine with 18X8 or 18X10 prop and its great combo. It fits nice under the cowl. Slimline makes inverted pits for it also.

Looks like inner most hole on the servo and outer most hole on control horn gives me the high rate of 1 1/2 inches at 100%.


I was reading back through the thread and had a couple questions about servo setup. Doesn't putting the pushrod closer to the shaft on the server give LESS surface movement?

Mine is setup on the outer holes on both ends and I had to crank the transmitter to 140% to get the recommended high rate travel. Am I asking for trouble doing this? I haven't even flown it on high rates yet, but I'd like to make sure I don't get any surprises when I do.

Thanks.

Status: offline 		Interesting to say the least. My 3250 will pull the 18x10 but it really likes the 18X8 better. I would be inpressed to see a motor .5 ci smaller pull the same prop as the 3250 at a higher RPM. I would guess the smaller motor would be more suited to the 16X8 prop. But hey, Im just a casual bystander, set it up with the smaller motor, If it wont pull the numbers it claims, send it back. If it does, you get lighter weight and less cost!


Tower does not carry the inverted slimline , I ordered mine from slimline itsself.

The number one rule in buying any engine is NEVER believe the HP numbers. The 3250 will turn 7700 with a normal size prop (18x8?), so that 3.28 figure is believable, but there is no way a 2300 will turn 12600 on any prop you would ever want to use. My 2300 ran very strong, and it turned a 17x6 at about 9000. I don't have the formula here to figure it, but at 9000, the 2300 is probably making more like 2.6 BHP.

As every racer knows, there is no substitute for cubic inches.

Status: offline 		A G26 might fly this plane, but would be a little lite on power. The G38 would be very heavy. I would get a Brillelli 40GT for this plane if you want a gasser. It is only $40 more than a G26 and is a few oz's ligther than the G26 with the power of a 40cc engine. The suggest Fuji BT32 is 9 0z heavier than the Brilleli 40GT.

Just my 2 cents.

Seems to be to me. Had a couple of hard landings on the first day, one in a recently harvested cornfield cause it deadsticked and couldn't get it back against the wind. Nothing seems to be bent or broken.
