Status: offline 		parkflyers.com offers an aluminum spinner which they claim (?) makes the Cessna fly better.

The Cessna will fly better without the rubber spinner.

Status: offline 		Just bought one of these Cessnas as a first flyer. Reinforced the model with clear fabric tape as per suggestions by others in this forum.
Have not flown it as yet because I noticed that when the motor shuts down due to low battery the control surfaces ALL go mental for a few seconds.Nothing is being sent by me from the Tx to cause all surfaces to do the jiggaloo. This is just beeging for a crash. Anyone have any idea what is causing this behaviour. The antenna is isolated from the servos and motor but it appears the Rx is getting cross talk somehow and sending controls surfaces nuts all by themeselves just as the motor shuts off. No way this thing will glide in on a dead battery without a major bash up.

Thanks for any thoughts

Status: offline 		Hi cpt Kirk ,
The only thing I can sugest is how far from the plane is the tx sitting ? sometime when its too close you can get cross talk .Im not using the stock radio gear that came with the plane { only the servos } I prefer to use a branded system { futaba , JR etc } for the tx and rx , Im a big believer in spending all your money on the radio gear cos you get what you pay for .I've had my cessna for 8 months and it flys great I have made a for mods to it and can highly recommend the Li-po upgrade to 11.4v much longer flight times and the extra grunt is great ! if you scroll back to about page one on this thread you will find a picture of mine and a list of mods hgope this helps.

cheers

Status: offline 		This is my story of a art-tech Cessna 182. I use to fly gas many years ago.
This is a fun plane. Here’s my list of fix’s / improvements.
1. Move the rear to horns back 1/8 - 3/16. This improves servo & stick accurate
2. Unplug 4th channel and pin flaps . This plane as plenty of control for beginner.
3. Make sure wing is level with tail. Easy when gluing tail, but can be done by lowing wing on one side.
4. If servo’s moves when in use glue them . Again helps accurate & repeatability
5. Clear tape is great. Include the cowling and tail. Not the flaps.
6. Cut off ¼ of rudder. To reduce over controlling.
7. Make sure flaps move freely. Clean out were there isn’t a hinge. Saves battery .
I also found that low temp glue gun works great. Just a little will do.
CG is one 3rd of the wing width, back form the leading edge.
Fly’s slow and level without motor running and flaps almost level
It has gentle movement from the sticks but still plenty to get in trouble.
I fly without landing gear and have removed aileron servo to lighten .
Prefer to launch off a small hill. The only thing I miss is the power to get out of trouble
that gas gives. I believe you point a gas plane and fly a electric.
G3 software demo is free and a great help to beginners (no radio needed)
Airs-screw prop 7-4 works great and sounds smother.

Status: offline 		cptkirk,

Did you do a range check? That is, walk away from the plane with TX antenna collapsed to about 60 feet or so. If you can control everything thing well from that distance, then it will fly well with the TX antenna extended.

The RX on the Cessna is a single conversion receiver and susceptible to interference. We fly on sundays, and every single TX in the field interferes with the Cessna regardless of channel being used by the other TX's.

I finally solved the problem by installing a Parkflyers Typhoon receiver and I no longer get interference problems at the field. Also, the Typhoon TX has HI and LOW rates which helps a lot.

If you purchased the Cessna from Parkflyers.com, talk to Marc there and explain the problem to him. He may want you to ship the RX back to him and he will send you a replacement -- It will most likely be the one being used on the Edge 540T which is a better RX.

Hope the above helps out.

Jmir

Status: offline 		Thanks so much for all the feedback. Nice to meet a group of people who care enough to share their knowledge.

Verdict seems to be the Tx and Rx are cheep. Oh well good for a simulation stick setup.

I'll take the advice. When I ran up the model the Tx was close to the model. Perhaps this caused the cross talk.

I know that if this thing does the funky mombo as the motor shuts down while flying a guy could get twisted about it. Best go buy a good radio and reciever I guess.

Right now I'm a bit leery of flying it at all.

The range is great, go anywhere you like and still have control. BUT once the motor powers down every control surface does the boogaloo for a second or two until the motor has fully shut down. Before or after that point control is deluxe.


As a guy kicking rocks down the road of life with this hobby. I'd have to say I'm not super impressed with the quality of this model. Good thing I used to build them as a kid and play with line flyers because without some prior knowledge I'd be................ well, smashing up with this model as a beginner RC dweeb.

Things like servos that move around and come unseated are just begging to cause a brutal malfunction. If it teaches me I'm willing to learn but next time something with a bit more quality

Thanks for your thoughts all

Like Grandpa used to say "Son, if we all liked the same things everyone would be trying to poke Grandma."

Status: offline 		Hi Cptkirk ,
Th problem your describing could be related to the ESC { electronic Speed Controller } it sounds like it { the ESC } doesnt like the low voltage and is struggling to supply the onboard BEC { Battery Eliminator Circuit } which powers all your electronics that would be my first port of call , I too have replaced the stock standard ESC with a robbe 819 Li-Po ESC and its great .Dont be put off by the shoddy parts when you get this in the air its worth it { if your into a scale look } I dont do aerobatics with it as I bought it to re-train on { after 15 yrs away from the hobby } .

For what its its worth start with replacing the ESC if the problem persists replace the RX .I generally only buy ARF models as I like to use my own radio gear cos I know where and what its been through ,you only have to look at the heli guys who fly gas they spend the money on the radio side of things as after all it is what keeps your pride and Joy in the air ,anyway enough woffling from me .

cheers

Status: offline 		cptkirk,

You are right. That boogaloo does not sound very good at all!
I would not fly it under those conditions either.
The plane flies great and looks very real in the air, but you have to have the proper electronics or you're are asking for trouble.

Status: offline 		I agree, it only takes a second and a relatively minor servo glitch to lawn-dart a plane into the ground at high speed. Mine had the same problem, got the twitches after the LVC kicked in so I stopped flying it to cutout and bought an 1800Mah 2S LiPo pack.

Shortly after that the ESC burnt out so I replaced it with a LiPo compatible $25.00 - 25 Amp ESC and that fixed up all my problems!! I can now safely fly the Cessna with 1800mah pack down to a 6.0 volt cutout.

Status: offline 		Hey everyone, happy new year! I'm wondering if anyone has replaced the tape on the ailerons with pinned hinges before? I got tired of the tape un-sticking, so I purchased a pack of medium nylon pinned hinges made by GreatPlanes. The instructions say to position the hinges in the center of the wing/ailron. I am concerned with getting the hinges to line up straight and I thought it may be easier to position them on the bottom where the tape is. Any thoughts or experience with this type of change?

Status: offline 		ive spotted another minor flaw which may be causing the crashes after hand launches, if you look at the servos they move. as such the elevator isnt getting enough movement. ive glued mine in and thats stopeed the problem... just something to consider checking tho

Status: offline 		This airplane is better described as an almost ready to crash. I decided to buy a new and upgraded ESC as the stock one has now decided not to run the motor at all. Bought it from Ebay and got a decent deal on the kit so I have learned a lesson.

After doing all the mods described here the thing should fly hopefully stable as it seems it has for others. No doubt about it though, locally I could have bought a nitro trainer 60 " high wing with servos engine and muffler installed with midrange Futuba radio for about 400.00 Canadain. (Hangar 9 Alpha Trainer) This Cessna foamy ends up being a little more than half that cost with extra batteries, balsa, ultracote, ( built a new balsa tail assembly, elevators and rudder) spare props and new MX9240 ESC.

Seems a lot of people here have had some fun with this model. If it's at all unstable after all the mods I've done it may make a good T ball target though.

In a few weeks, off to pickup a better airframe and schtuff. So it has served a purpose to whet an appetite for construction. Will post some pics of either a safe landing or a beer cooler with wings.

Status: offline 		right i got mine airbourne for the first time yesterday and ive made a few alterations.
1.glued the servos in - they were wobbling and causing a lack of elevator movement
2.changed the elevator connection to the most outward hole on the servo horn - gets more elevator movement

oh and the other thing that caught me out was the nose landing gear...it folded on an "iffy" landing and the wheel cover actually peirced the fuse....

other than that its a nice little plane when you get it going, quite stable and has excelent low speed handling. much better than the aerobird extreme which i spent £20 more on and had a lot of hassle with
