Richyp, thanks for the pics of the engine and its setup. I guess I am going to have to live with my spinner backplate being about an 1/8" away from the cowl. The carb neck on the Saito 120 just sticks out to far to get any closer to the firewall. If I could find a way to do a short right angle and reposition the carb, I could get closer to the firewall. I have looked for a solution, but most of the adapters I have seen are for exhaust and not intake...

well I am nearing completion of mine... I thought i would try the pull pull that came with it. WRONG the 2/56 thread rod is 1/56. nothing will fit it for a clevis not even the ones with the plane. so i put that with my wheels.

what they should do with this plane is take away all the hardware and offer the plane for $139. after paying for plane+shipping, paying to ship back and then for hardware i could have bought a dave patrick extra and had enough left over to buy the spinner, Man i sure hope this plane flys well.

well anyway when my new pull pull gets here all i have left is fuel tank , spinner, throttle cable hookup and im done.. [:

Hi all
Just ordered my Cap Maniac at the NW RC show. After reading all of the posts I've noticed no one has mentioned how it flies. Also, those that put the OS .91 vs the Saito 1.00 who thinks they have enough power? (and I don't need to hover at 1/4 throttle, 1/2 is fine) The Saito advertises at spinning at 9k vs the OS at 11k though the Saito is 3oz lighter than the OS. Talking to the BME guys at the show they recommended the OS .91. what about the 2 stroke OS, more horsepower for the same weight as the Saito?
As far as the hardware goes, they even said for serious 3D flying that the supplied hardware is not adequate, however for Sun afternoon flying it would be fine. (so just dump the hardware package all together I say...)

anyway, thoughts????

well richy is the only one of us so far that has flown his..

I am using the O.S. 91 on mine and think that it was designed around it.. for example my cowl fits at the recomended engine placement and no one elses did.. IMO the saito will make more power.. If the plane is kept around 7 lbs either motor will be fine. for 3D

Was that the two stoke or the four stroke? I'm at 2,500 and I do lose some power on the engines..


Thanks

4 stroke , at that elevation saito 100 would be my choice on 30% nitro

getting very close now . I got the Du-Bro pull pull and have it installed. Looks like my cg will be on richys 4 3/4 with everyting in the trays that were provided.. i dont have an AUW yet will get it soon.. MAN this thing looks beautiful when wing is on after completion. I sat back looking at it so i took a couple of pics.. one of the pull pull..

Lee,

Looks like your Garage belongs to to the RC airforce... dude, you are really addicted... there are drugs for that.

He He that is my basement.. There is a more on the other side Im packed in a corner to work on them.. I dont know which is more addicting.

Well I just could not get the Saito 120 to fit in the cowl so I went and picked up a magnum 91 4 stroke, Richyp what experience have you had with them? My other non purchase alternative engine was a Saito 72, it would have flown, but that's about it.

Chasman

btw drumbum if you're worried about stepping on one of your planes I can hang it in my basement.....

let me think about it UMM no .. magnum should do fine watch the nitro they like 10% they will actually "spark knock" with more than 15% and be down on power due to detonation in the cylender. Alot of guys at our club are running them. I have an ASP 91. Im told they come out of the same factory. My ASP has just as much power as my O.S. 91 pumped does.

Good to know about the Nitro. I have been running 30% in my Saitos'. I'll run the 15% in it and see how it runs. Thanks.

I see that Forest is just down hwy 29 from me. You ever fly at the F.A.R.M club in Bealton? That's the field I fly at mostly.



Chasman

No i havent i will have to come up sometime .. I fly in bedford just 10 min from here. about a 200 acre field. our club is VA aeromodlers,, there is also a note on TOWERS site that mentions the nitro last time i looked. I was going to buy a magum 80 but they discontinued them. for a flip 3D..

here are some areal views of our field taken from a foamy http://www.kites.org/power/aerial/aerial.html

Dupe post..

Nice field, I wish I had some of ours. We fly off a private field and working farm with a 3000 ft grass strip. The owner was a Nats full scale champion a while back. It's a blast to have the full scales go blowing down the strip at 200 knots and 10 feet off the deck!! Wow.. Come to think of it I may have a photo or two, not airborne though..

Btw we are across the hwy from the Flying Circus if you know where that is off hwy 17..

Another CAP Maniac takes to the air!

First, check out the tail feathers bracing... this was just too easy, and solid as a rock. A pull-pull rig thru the fuse and control horns on the h-stab... duh, why didn't we think of this before.

The guts all finished, and the vents cut in the cowl.

Then the flight. Only took it up once, a little windy, but she handles like a dream above 1/4 throttle (Saito 100 running RICH). Smooth rollout and steady climb at 1/3 T, then 3 clicks down and two right, she was straight and level. Dropping throttle below 1/4" she rises and floats, had to push down to get it to land. High idle (2800 r's) was all we could get it down to, so it took all the runway to land it, it just kept floating.

Didn't ring it out, but good pull verticle over 1/2" throttle. Rolls at low rate real snappy, on high rates it is a corkscrew from hell. Stalls into the loop at 1/3 throttle, but perfectly square in and out without any rollout. Slow flight is real stable and easy to manage. Not a hind of tip-stall, even at low speeds. This thing flies easier than the trianer at 1/3 throttle.

Didn't try inverted, but looks like the engine is pitched down a bit, so when you chop throttle is pulls up and floats. More flying to be sure of that. Went verticle WOT once, running a bit too rich still, sluggish but kept going. Easy to handle on the ground, doesn't turn on throttle-up much at all.

She's a keeper, no doubt. With some time to really get the feel for it, I think it will be an awesome flier. What little I did try, it behaved. I think 3D will be good, but I'm no pro, so I'm not too sure. I held a hover up high once for a moment, and it seemed real solid.

looks like i will be flying mine next weekend if weather permits, it is compleated.. still no AUW yet but will post.

good to hear on the successfull flight ..

Looks great! Nice idea on the tail bracing. I have been breaking in the magnum 91 I put on mine and even with a DuBro iso mount the horz stabs shook alot. I am going for the bracing to ensure they don't vibrate off!

Btw what size were the horns you used on the tail brace? Looks like a better way than to stick a wood plug in the stab and then drill it out for a screw.

Flew mine today with a saito 100 in it, last week it was electric at a touch under 8 pounds and with the 100 in it 7 3/4 pounds. Flys great, harriers, hovering, great blenders into waterfalls and then land at a walking pace almost.

Yea Lee, two successful maidens in two consecutive weekends... yehaaa. The Funtana 90 last week, and the CAP this weekend. Sure is nerve racking to take a new bird up. Alas, they are both good ones, no suprises or bad habits. Now we gotta learn to fly these very capable birds like the big boys... the sim is going to get some healthy workout now.

Any thoughts about the float/rise on thottle down? Is it a good assumption about the engine being down-pitched?

Chasrb,

All the tail harware is standard Dubro 4-40 hardware with #6-32 attachment screws. The whole thing only took about two hours to fab and install. It's really tight, and adjustable too. We're really pleased with the clean and neat install. I don't have the packages, so I can't give you the part numbers.

We are 8 lbs 4 oz AUW. CG at 4-1/2. Zinger 14x6 wood. Low rates are pretty soft, with Ailerons and Elevator at about 1" defeltions. We upgraded the elevator servos to Hitec HS-6635's, still have plain HS-425BB everywhere else. Needed the digitals to better syncronize the elevators. Boy, you can really tell the difference in servo quality when you have cheap ones alongside good ones. Speed, smoothness and centering are SOOOO much better on the digitals. We'll upgrade the ailerons and rudder soon too, damn things are so expensive. Wish we had understood this early on, so we wouldn't have wasted money on the cheap ones.

Here is a snapshot on takeoff... totally easy to manage. I am very happy with how well behaved this ship is in the air. With healthy expo (40%) on low rates, anyone can fly it. Flies straight and solid, aileron turns are perfectly self-coordinated without rudder at low speeds. I love this plane. If you can get past all the poor quality hardware and fixing the bad fit on parts, it's a great plane in the air. If we can solve this floating and get the idle down to 2K r's, it will be perfect.

This Saito 100 has not been behaving well, just not broken in yet. We did a little trick a veteran showed us at the feild, where you pull the first coil out a bit on the plug, helped a ton. Before that, couldn't get it to idle smooth below 3200 rpm. It really labors at low idle speeds. We can turn it down to about 2300 now, but it is shaking the plane really bad. Trying to adjust the low-speed screw, but it's just not ready for that. Just impatient I guess, we only have a gallon or so thru it so far. It's running real smooth now at 2600-2800 r's, but it's too fast to sit still on the runway. Makes landing a challenge, it just won't slow down enough. We'll try an APC 14x4W next time out.

So IFlyit... give us more flight report details! That's three in the air now, but sounds like you're the only one thrashing it 3D so far. Anything to report? Why did you change over from electric?

If you have a gallon of fuel thru the 100 it is more than enough time to adjust the low end needle, I adjusted mine some after about 4 tanks and check the valves also. After 40 minutes it should be broken in like the manual states, figure 10 minutes a tank and a gallon is at least 4 tanks, many more actually.
If you kill the throttle and the plane balloons up you need to add some upthrust to the engine, I had to do that on the electric version as my mount had too much downthrust in it. Too much downthrust will also make it pull more to the wheels in knife edge.
If you have too much downthrust in it flying at full throttle will require some "up" elevator trim to fly level, when you kill the power the elevator trim makes it balloon up.

I flew mine electric and then put a Saito 100 in it as I am writing a double review for Rcgroups and I did the electric first and am now doing the glow one.

what are you using for hardware? and will that be in the review?


Tman, yes it does sound to me like a downthrust problem. how did it track verticle. also did you have to hold up in it inverted at full throttle and then down off throttle. if it is changing it most likley the poroblem. A 14x4W is too small for the saito 100

I used the stock horns on the elevator and rudder and dubro ones on the ailerons with 4-40 linkages.

How did you bolt the stock horn on the rudder? did you use the pull pull and stock clevisis. you could just pull my clevises right off the stock pull pull .. 2 of my horn backings stripped with very little effort too.. I think i ended up with about 3% of the stock hardware and tried to use it all..

I am still debating on using the stock wing bolts. to me it seems they will vibrate loose. im thinking of switching to nylon

I just put the horns on and put a bolt thru them with a 2-56 nut on the other end. The stock wingbolts have held up fine so far, I thought about switching to nylon too but didn't. They give you lock washers to use on them so be sure to use them also.
