HOPEFULLY +1. But IMO building your own kit is an option only if u have the nerve to fly the heck out of it after 3-4 months of benchwork. I personally dont.
I do though respect idividuals that take the plunge into going the kit way but as is he case with QQ and some other quality arfs a little bit of cyano and glasscloth is usually enough to keep trouble away.

bblue, i'v been flying r/c since 1974, u control and scale free flite before that. still crash now and again. just part of the whole r/c thing. never let it bother me for more than few mins. sure, i wish i had not put it in but i just pick myself up, dust myself off and go on to my next project. i build to fly no mater what happens. some of my planes last for years some don't. i love this hobby. i have QQ yak arf and i love the thing. good example of a well built arf, he demanded it so. :D

RE: Quique Somenzini YAK-54S 73
 
I agree with you. Though I joined the hobby more than 10 yrs after u did my primary Interest had been helicopters. It is only the past 5 yrs that I almost switched to fixed wing and I have built a coule of kits myshelf and I know what u mean. The one was an old Piper Cub from FLAIR (UK based company not longer in buisness as u propably know) and the ATTILA from GP...

Back to present.
Thinking of going the inverted installation with the OS 200 using the optional adapter but at first glance it looks like the stock muffler will not clear the cowl anyway a turn it.
Seems like a Keleo pitts muffler would do the trick.
Does anyone have experience with these products?

RE: Quique Somenzini YAK-54S 73
 
careful w/that inverted install. 4stks hydrolock easy in that position. also, as per clarence lee of k&b fame says not to invert 4stks. you can experience flame outs and idle probs. you can side mtn. or maybe at 45 degrees from inverted postion. i personally side mt. all my engs. never have flame outs or idle probs. easy to keep tank on center line, etc. just my 3$ worth

RE: Quique Somenzini YAK-54S 73
 
Seems like I will be going the 45 degrees from inverted postion installation and use the stock muffler.
Thank you all for the input.

ORIGINAL: BBBlue

Just checked the link u gave Steiny .
Dont know about the others but the 73'' Yak looks definately identical to the one I have. Everything from woodwork to hardware , wing mounting system etc. everything apart from the tailwheel assy & paintwork...
Checking with the European dealers even the price region is very similar to the one mine had when it was available. Hmmm there's something fishy up' here...
There's nothing fishy about this at all! The people at Hi-Fly built QQ's planes for him. When his partner retired and QQ went to work for Hanger 9, Hi-Fly picked up the line. The designs may look identical to the QQ planes but there have been some minor improvements in the design, thus giving a stronger, lighter plane. However, all the replacement parts, such as cowls, canopy, wings, etc will fit the original QQ planes, making Hi-Fly an excellent source for replacement parts.

We, at Southwest RC Engines located in Tyler, Texas, are presently the only authorized dealer in the US for Hi-Fly Models. We can deliver any Hi-Fly arf or part within 5 to 7 days to your address. Check us out at www.swrcengines.com

Clearly there is genuine interest for replacement parts for the QQ line of planes. However, in order to comply with RCU Forum Rules, please address any questions concerning pricing, availability, etc to me either by PM or directly through my website at www.swrcengines.com.

This is really exciting news as such is the case. Good to know an excellent product is still in production even improved. Keep up the good work and the word will pass on.

that's great news....I need a new canopy for the 73 incher yak. Dropped it and it cracked !

RE: Quique Somenzini YAK-54S 73
 
I just got this plane all built with servos but no motor my qustion is I have new saito 150 or I have a new OS fs-200s what motor would be best of the two

Thanks Tim

RE: Quique Somenzini YAK-54S 73
 
I have no experience wih the Saito setup so....
The OS setup (especially if it is the pumped version you own) with an apc 18X6W is 100% successfull.

rcpilot_971 02-07-2010 12:02 PM

RE: Quique Somenzini YAK-54S 73
 
its the non pump

RE: Quique Somenzini YAK-54S 73
 
Get yourself a Perry Pump (the oscillating type) and locate the tank in front of the wingtube close to the c.g.
No need o use a HP tank. Use the stock one.
You will be amazed. The plane tracks straight either way with very minor adjustment.
Mine is the pumped one but I have seen the setup above performing faultlessly on a Giant UcanDo.

RE: Quique Somenzini YAK-54S 73
 
did you use the stock muffler if do you have any pictures of the motor in the cowl I was thinking of going witha YS and not mess with the os 200 and the perry pump



Thanks Tim

RE: Quique Somenzini YAK-54S 73
 
Place the engine so that the cylinder head points at about 130deg (8:00hrs clockwise as seen on the firewal)l and u can use the stock OS muffler. This is a common practice recommendend by Great Planes at their manuals.
No problems with engine - it runs as reliable as ever.

YS is by all means a very good choice. Consider a soft mount if U go that route (weight). YS are powerful beasts that produce increased vibration at both tickover and throtling.
Still the best choice if UR familiar with these motors (I only had the 110S for some time). LIghtweight and powerful but tamperamental IMO.

P.S. Get yourshelf a good tank designed for high pressure systems to get a reliable running YS -possibly by TETTRA from Central Hobbies.
Good luck.

Ok I will take a look at that do you happen to have a picture of your os 200 mounted in the yak with the cowl on. also did you need to use a onboard glow driver or a remote glow driver. how did it ballance out with the os 200 on it

Thanks Tim

RE: Quique Somenzini YAK-54S 73
 
Sorry cant upload picts (hopeless)!
NO need for a glow driver. If u feel the need for a remote booster use it for your convenience - I dont (weight).
I balance mine at 178mm behind the leading edge measured at the root of the wing.
A bit tailheavy , I know (slight climb when inverted).

But.
Flies like a dream , effortless hover, perfectly level flat spins, less rudder at KE etc... No landing issues at all. It just flares by itshelf when at landing speed and touchdown. These come out of my own experience with the model. There is plenty of feedback on CG iside enen in this thread.
To balance at 178 I have built a small tray at the 2nd former behind the rudder servo out of scrap CF tube sliced and epoxied between the formers at the bottom on wich I cable tied my battery pack (Hyperion LiFe 2S - Flighteck 5A reg, to be safe). U have to cut the yellow covering undernetah to gain access- no big deal- the new patch is merely visible.
Put it on the GP balancer set at the desired length without the battery pack and u will find the sweet spot with the aid of the batterys weight.
Iknow 1picture is 1000 words but I gave my best effort to explain here.

I am still looking for a cowl for my 73 qq if any one has one.

I am not sure if balancers were ever mentioned,but after years of constructing CG devices and hang balancers I found the "one stop answer" to all the messing around with home made units. It is costly but if you plan to stay in this hobby ( for me it has been 54 years ) this is the answer.

I think I read that this plane needs nose weight I do have a saito 220 sitting hear 38oz W/out muff Im not sure if it would be to much for this plane I think it was turning 300RPM more than my saito 180 with a APC 18X6 wide

Email ''Lindinger Modellbau'' , very highly regarded firm in Europe based in Austria , you may be lucky. This is where I got mine 3 months ago for about 50,00€ delivered.

rcpilot_971
The plane balances perfectly as per manual. It is only my personal preference to shift the CG rearwards.
Remember wing loading if going the Saito 220 route. By all means keep it lightweight and u will be rewarded with an excellent perfrormer.

Flying Weight makes all the difference.
