mtwister...

My Cap with the EVO weighs 13lbs 5ozs. That's with nothing special to make it light. It is a real fun plane to fly.

My guess the Moki is lighter than the EVO. It weighs about 60ozs with iginigion and muffler. Plus you have to have the extra ignition battery which adds another 4 ozs or so. So it's quite possible this plane could weigh 12.5lbs with your Moki. It would fly wonderfully at that weight and power.

Great price on them right now too...$270 with the discounts from Tower. And if you're a super club member you get free freight. Pretty inviting if you ask me.

Thanks
Barry

Barry,

Thanks for the info. The Moki is 41oz without mufler, so probably close to 50oz. with muffler. I am a club member of Tower, and just ordered the plane

Mike.

Great choice! I'm sure you'll be happy with it. I decided to go with a OS 160 in mine. (I saved the Da for my new Aeroworks Yak) With the Moki it should still be light on the wing and be a rocket to boot! Some great info on this thread.

Could someone help me out?
I'm running am OS 1.6 with 18x6w APC, is this too much prop, I also am running a fuel pump, 15% fuel.
The engine pulls good but a little doggish when going from low rpm to high, Just wondeing if I'm over propped?
thanks

Hard to tell if you're overpropped without knowing tach figures, and engine temps.

I would say yes it is

What do you mean by "doggish"? Is the engine cutting out, burbling, alot of smoke? Does it catch itself ,then the rpms increase? Low end might be rich.

An APC 18x6W is the perfect prop for that engine. If it's stumbling going from low to high your low end is a bit rich which is common when running a pump. The high needle may be a bit rich as well. If it tries to cut off then it's too lean. the pump will make both needles kinda touchy and if the pump is turned up then both needles will end up being closed more than usual. This is common with both types Perry pumps

Tach it for max rpm then back off 300 to 500 rpm for the high speed needle. Then start leaning the low speed until it transitions instantly from idle to full throttle after idling for a minute. During that minute the idle should not change. If it does and picks up rpoms then the low end is too lean, if it looses rpms then it's too rich

Good advice Bubba.....Is it true? Your not going to Toledo this year Bubba????[&o]

Yea,

I'm not going. I had a last minute change of plans that requires me to be here on Saturday. I may still come out on Saturday night for Sunday

Basically Sears was to deliver some new appliances on Friday but changed it to Saturday. My sister was going to be here to let them in but said OK to the change not remembering I was going away and she cannot be here on Sat so I'm going to have to be here. RATS

Thanks very much guys, to be honest I thought it may be rich on bottom but thought I should have a second opinion. I have checked rpm's, about 3 months ago, tops out in the 83-8500, turned it down to 7900.
Once again thanks guys.
I was nervouse to take it out again, on maiden flight everything went greatrun great( minus the bogging) then on landiing the the landing gear ripped out. On further inspection the firewall wasn't glued in[] Just one more reason to pin the firewall and just because its a ARF, check it over anyhow.
Any who, had it out yesturday and run 4 tanks of fuel though and zero problems, what a beatiful plane to fly!!!

That it is...

Man,great thread.
I just came home with this plane. I had been eyeing it for a while but I have yet to maiden mt W.M. Extra 1.60. I just stopped at my LHS for some minor stuff and they talked me into taking it home. At $325.00 OTD, well, "hi honey, guess what. I just spent about 2 hrs reading this thread from the start and I'm stoked to get started. The only undecided issue is whether this plane will be my induction to gas and if so which engine or a Moki 2.10(maybe my BGX-3500 if maiden does not go well with the Extra. Just saw tomorrows weather forcast...high winds, bummer. Oh well, I'm going to tighten up the covering, Take the wife to dinner(recommended on this day), read the manual once more, get up early and get with the build.
I'll post some pics of the set up and my engine decision soon
Fly 'em low and land 'em slow.

It will go together for you pretty easy Balsafire. Mines basically stock, only thing I changed is the tail whell set up to a Sullivan. I used some Dubro quick connects on the surfaces. Also, I pinned the firewall with some 1/8" dowels per Bubba's recomendation I went with a 160 FX on mine. Alot of great info on here. Enjoy!

Hey Sewer dude.
Yeah, I plan on using a 1/4 scale Klett tail wheel on this one. I used one on my Extra and it worked out really cool. My wife decided my penance would be to bbq steaks at home(some punishment). I tightened up the covering, lots and lots of wrinkles, attached the aeilerons and joined the wing. One mishap, the wing bolt plate was warped and when I tried to glue it on and use the wing bolts to straighten it out it cracked in half. No biggie, I just went ahead and tightened the bolts and after it dried I ironed a peice of covering over the crack. Can't even tell. This plane is so well put together. It's the same series as their 80" yak. I had one about a year ago. It had all the servo's(5645 mg) and everything installed except the engine and was stolen along with EVERYTHING else I had related to rc.

I am also going to pin the fire wall per Bubba Gates instruction. I will use the stock horns but will probably upgrade to some type of ball joint rods. I'm going to check out some of the cool stuff from Rocket City and see if it is cost effective. Also, I plan to use only 1 servo, probably a 8711 set up pull-pull for the rudder with 5645's on all the other surfaces. Still undecided on the engine but I have time and right now I'm leaning towards a Moki 2.10. I'll probably change my mind several times. Only time will tell.

Trim wise I am going to experiment with 1/8" gold pinstriping on the red and blue. Also, in the May, 2007 Issue of Fly RC I read a review on the BVM 2.6 Edge 540. The scheme is such that it looks like the front covering is torn away to reveal a checker board scheme underneath. I want to do something like this between the canopy and the cowl on the top of the fuse. Something to the effect of a hole torn in the top to reveal an eagle flying straight at you wraped with a U.S. flag or a flag background. Lofty goals but what the heck. I will practice some different methods on seperate peices of Mono-cote and IF i get somthing I like I can apply it using trim solvent. Man, I'm rambling. I'm really excited about this bird. Anyone's advice on how to do the scheme I described would be appreciated and if I'm crazy, let me know this as well.

I'll post some pics when i get the basic airframe done. Oh, by the way Sewer Dude given your handle are you a plumber. Been one myself for twenty years. Just curious.

Back later,
Rod

Balsafire,
Glad the Cap is going together well for you. Heck, you got the wing together, thats the hardest part of the whole kit I used only one servo on the rudder as well, a 5985 and 645 for the rest.I think I'm going to go to 6 volts to speed things up abit. The wrinkles seem to be the norm with this palne, I had a ton on mine as well, they come out, just takes some time. The trim scheme you mentioned really sounds like it would look great. I always liked the tear away look. As for the handle, no I'm not a plumber. I'm a supervisor at a WasteWater Treatment Plant. Its a crappy job Keep us posted on your progress.

You'd probably have to put the servos in the tail with a 1300 gram engine. I ran the pull-pull with the OS 160 and pitts style muffler but put the servos in the tail when I switched over to the SPE 40cc.

Take a look at what's leaning against the wall in the background I'm pretty excited to get the Cap done. I have high hopes for the Moki 1.8. I am going to buy a smoke system and install it once I have flown her and make sure all is good. I am hoping this plane will allow me to compete in my 1st IMAC comps this summer.

Mike.

Al, or I mean Lou55. Where did you end up placing your battery and receiver on the Cap. Getting ready to balance and wanted a head start. Thanks

Anybody flying this plane with high torque nylon geared servos?

Swerdude,

Just finished balancing mine. On my Cap I am running an Evolution 45GT for power, two (2) ea. 2600 LiIo for radio and servo power regulated with a Smart-Fly Super-Reg feeding a Hitec Fusion receiver and a ElectroDynamics Research EDR-11 Pow'r Bus Pro. My ignition battery (2600 mAh LiIo regulated by a Smart-Fly ignition regulator) is mounted in the engine box, the receiver batteries are mounted behind the fourth former. The receiver and the EDR-111 are mounted in the port tray, and the choke and throttle are located in the starboard tray. Additionally I have a TME smoker pump unit with a 2000 mAh NiMh battery and one 11 oz. fluid tank at the C.G.. I am using only one Hitec HS-5645 MG servo for the rudder, and it's mounted in the rear.

With the addition of .75 oz. to the rudder servo case the plane C.G. balanced perfectly at 5.75 in. from the leading edge at the root.

Nice radio job Air tech...Really clean[8D].
What is your auw dry?

I'm betting 15lbs give or take a couple of ounces. But smok on this plane should be sooooo coooollll

All up weight is of 15 Lb. 14 oz.. I am waiting for a 2600mAh LiIo to power the smoke pump. That will save me 5 oz. from the dry AUW.

Since the smoke system is modular I can remove it at any time and that will save me around one pound.

Just got my cap ready to fly. Having a litte issue with the CG. Anyone flyin with 5 7/8 cg?? Manual says 5 3/4 is this plane that sensitive to the CG?? thanks for any help.
