After building this plane, it doesnt really seem like the hovering type......and from what I read, it doesnt land as bad as the usual Cap ( IE, doesnt need alot of speed during landing )...but others on this forum who have flown it can answer that better.......

Hey all, Another flight report:

I couldn't take it anymore, I put the skies on her. Today me and a buddy went to a local pond. It's moderately windy today. 10mph with gusts to 15mph. This plane is excellent in the wind. Stays on course and dosn't get tossed around that bad. I made some sweet 2 point touchdowns with the ski's. I forgot how fun flying with skies is! I didn't do too much aerobatics today, few rolls and such. Mainly practicing touch and goes. I made the 2nd and 3rd flights today. These flights are the first since I re-adjusted my valves in my OS.70, man I forgot what power this engine makes. Takeoff with a pull to vertical followed by rocketing out-of-sight was great. I am sure the nice dense cold air helped though. It's only 34*F out. Makes it cold with the wind. She dosn't need anymore power than a .70 or .72.
Happy flying!

Good to hear.....I put the OS.70 in mine...all thats left is to put the battery and receiver in it, set the throws, and balance it, and it will be ready to go!

Hi all,

The directions reccomend 54 oz-in torque for the servos. I have a futaba radio and the standard 3004 servos don't have enough torque. What servos should I use?

Look there. It's all of futaba's servos with the specs. The 3004's have 57oz/in of torque @ 6V. A good 5 cell pack will let you use those servos.
I run a 6v 1100MAH pack in my CAP, I have 3004's all the way around. It flies fine with them. I am planning on upgrading them as I see fit.

I am wiht Sean on this one... I'm running 3004's in mine too with a 1800 6v pack.... I am still playing with the cg on this thing... I did notice some "Capish" tendencies this past weekend but I could almost pull off a knife edge loop with the Saito 100...but it is still breaking in and was running a little rich.

Man I am glad I caught this. I have 3004's in mine too, but I only have them hooked up to a 4 cell NiMH pack. I missed reading the 54 oz. spec in the instructions. Thanks guys.

Maybe it's a good thing the weather has kept me from flying it.

Futaba has two different high torque servos, 3010 and 3305 that are inexpensive if you want to upgrade....the later is metal geared. The 3010's have more than enough torque and sell for around $25.00 each! I use them in my UCD .46............

hmmm, thats a good call there... I have 3151 digitals all around which are not rated as high as what the specs call for... funny thing is I have about 50+ flights and have abused the hell out of this little airplane and have not had any issues... maybe it would be better safe than sorry and change them out.... thx...

As with any specs, I am sure they give you a good margin for error. 3004's on 4.8v would probably be just fine.

BR289

My Feedback: (106)

Usually the servos wear out quicker.On larger planes with larger control surfaces, the torque is more important because the weaker servos will just give out.
The surfaces on this plane are really not that big. I know people that have used standard servos on planes with large surfaces such as the U-Can-Do and they lasted for a while, but eventually wore out the gears, or during an abrupt manuver, gave up on them.

Well, I got my second CAP in the other day. Came with a free set of Klien pliers in the box. The first plane didn't.

.61FX mounted sideways with a Bisson pitts muffler swinging a 13x4 prop. I stripped some of my servos on the last go around so I might replace them with some Hitec digitals. Haven't decided yet.

Can't wait to get the next one in the air.

dajensen

I put all Hitec servos in my rig. the elevator and rudder servos are digitals, I don't remeber the exact number (5456 or some such I will check and post if anyone is intersted) they are high torque servos coming in at 87 in/oz and the cenerting is dead on. Given the control surface sizes the rudder and elevator were my only real concerns for servos other than the standard 425BB's. But just due to the spot on centering of the digitals I am going to put 4 of them in my show CAP580 ( yes I like the plane so much that I have 2 of them).

I'm glad I'm not the only one with two CAP 580's...of course, one of them is crashed so I don't guess it counts

hello everybody, just got through reading alot of this thread, i think i found my new plane, i have a fx91 with a slimline pitts waiting for a home, i need to overpower everything cause i'm around 5000', i looked at the bme cap maniac, but that thread looks bad, alot of negativity on that subject, so i may be ordereing this one real soon, glad to see what i have read is all pretty much good

cadconversions

My Feedback: (21)

dave, please don't put a .91FX in this plane. It's really intended for a .46 2-stroke and a .91 would be insane. BTW, when you get it done, be sure to post video

diamondave

My Feedback: (29)

yeh i know its out of the range, but the elders here say about 30% over power is good for where we are at, i found by going off the recomended 4-stroke size in a 2-stroke works pretty well, ya know, it may say 50-70 2stroke and 60-90 4stroke, i'd go with a 90 2stroke, i know even by that logic this particular combo is even beyond that, but i had my 91 in a stinger that was 59" span and similar size and weight as this one appears to be, i had to add weight cause it was hard to get my battery as far back as i needed, but i've gotten better at finguring those type of things out while assembling, i thought the gms 73 would be good for this, but like i said, i have this 91 burning a hole in my shelf

i apolagize if i missed it, but how is the 3d performance? i know this size plane i shouldn't expect too much, but i do,[>:] i've seen some comments on stability and rolls, etc, but has anyone found that the plane(not your thumbs) just won't do a certain type of manuver do to lack of either control suface size and/or travel?? i don't mean hovering, you can do that with a trainer if you got the right power to weight.[X(]

Cad you must think I am crazy putting a Saito 100 on mine But after flying it it would be a pig if you put the low end engine on it.

John

My Feedback: (21)

John, actually, I think a 4 stroke 1.00 would be completely different then the .91 2-stroke. The .91FX (per the manual) is very finicky on prop selection. I would only use the recommended prop for the motor on the chipmunk I flew that had the .91 in it and it was insane. The 1.00 4-stroke gives you more options for a large prop with less pitch.

The key is really the right prop selection for the motor used. I'm more than happy with my .61FX swinging a 13x4 prop but know there's still some room for more power without being nuts.

BTW, the recommended motor sizes for this plane is weird. It recommends a .46 - .60 2 stroke but only a .70 4-stroke. Normally you would see this as .60 = .90. Anyone have anythoughts as why?

DiamondDave:

The other thing you need to worry about at high altitude is the wing loading. The CAP has a much higher wing loading than your Stinger. You may find that the CAP turns into a tip stalling fiend at your altitude with a heavy engine in it.

If you really want an aerobat, I'd look for the lightest one you can find.

CadConversion, What kind of RPM #'s do you come up with for the 61fx on the 13x4? Have you tried a 14x4?

Back to the servo question. If I remember correctly, the photos in the instruction booklet actually show two kinds of servos mounted in the fues. Can someone double check that.

cadconversions

My Feedback: (21)

Didn't have a tach at the time I was flying so I don't know. I'll check it when I get the motor remounted. I don't have a 14x4 prop but I would imagine it would bog the motor down but I would still guess it to be flyable. My .61Fx seems really stout.

diamondave

My Feedback: (29)

i thought about that too, the wing loading, that stinger was a floater even with all the weight, my old pacific aero edge(60) became kinda squirley when i put an os108 on it, but it sure was fun, i have a couple acrobatic planes already, f90, ef yak 54, i like em both, may sell the f90 though, but i want a good plane for my fx91, i looked at the ucando, and the mayhem, there not bad and a good combo for my motor, but i got to be the odd ball, i want a plane that looks good too, and the more i look at this one, the more i like, so i dont want to put my motor in something like a superstik either, i was thinking if it would be way too much wieght, i could just part with the fx and get a saito 100 or that gms 73 2 stroke for this cap, i don't know, that bme cap is similar size and they say up to a 91 4stroke, so that leads me back to my formula about matching the recomended 4stroke with a 2stroke, it has worked well for me in the past, and the fx isn't rediculously heavier than the saito100, the pitts muffler helps out, that stock os one is heavy, so if you guys needed to put the battery up by the fuel tank or further, then i should be able to balance it out without weight, right?, so if it turns out to be just ounces heavier and not pounds, then i'd have one kick ass set up going on baby

Hey Guys,

How good of a pilot should you be before attempting this plane. I have flown Eagle II, GP Cessna 182, CG Cub, and Sig Something Extra. Do you guys think I should be able to handle this plane.

Thanks,

Ryan
