Exactly how are you trying to get the Monocote to stick?? Are you using an iron...are you using CA....????

Did you peel off the clear plastic backing before you applied the Monocote?

Please explain, and post a pic or 2 if you can....it will help!

Hi, what you need is get off all the grease form your wood. I've had use thinner (lacquer or polyurethane) and alcohol alternatelly to sock the wood. Use a cotton or a cloth to apply and rub it to clean the wood, like washing it. let it sock and absorb the solvent, this will dilute the grease.
Then, use some paper towels to dry the wood and put towels over the wood. after that, using your iron at the hottest setting put it over the towels. this will warm up your wood but the towels will absorb the grease. Change towels repeatedly until they don't absorb any more grease.
You can repeat the process if needed. after this you can use the balsarite. Let us know if it worked for you. In extreme cases the wood is no longer good and you have to change the piece... Hope its not the case. good luck!

i'll give it a try, the piece for my switch and charging port is new balsa, but had been handled alot. im guessing the grease and oils on my skin on my hands are screwing with it...i have probably cut 4 or 5 pieces of monocote to cover this spot just in the past hour or so before getting on here to ask for help lol

Try the next:
- clean your desk and put away everything you use to build: tools, glue, dust, etc.
- clean your plane with a cloth using windex. Personally I use a mix with windex and a grease cleaner. It will leave your plane with no grease or dust.
- use the cleaner for the desk too.
- wash several times your hands before and during the process.
- after all, wash your hands again and start cutting and applying the covering

Default RE: covering problem

thanks for the help guys, i did exactly that, every time i leave the field i clean the plane with windex so its not all over the car. minus this last time after i lawn darted it i just wanted to go home and be bummed, plus it was 9pm and the sun was pretty much down...i got it all back together about 15 minutes ago

in case anyone is wondering i had been hovering all day with no problem. till a buddy and girlfriend wanted pictures at the end of the day and the motor kept bogging down at full throttle, knowing i needed to adjust the carb i thought i could atleast get one more decent hover for a picture, sadly i guessed wrong lol. got in a hover at about 15 feet and it died, nose dropped and into the ground it went semi level messing up the landing gear and muffing up the blasa where the switch and what not was at....lesson learned in all this, peer pressure can me a nasty mother with the influence of the words " just give it one last try" lol. but in all it was fun and it will fly again

picture of the landing gear after the belly flop....they are now straight again





this is how the plane usually looks

OK.....here's a quick and fast solution to your problem. Take rag and some alcohol, wipe down ALL the surrounding covering.

Cut a piece of the new Monocote, at least one inch bigger that the entire patch area. Using your Monocote iron, set on about 2-2 1/2,
attach your patch to the newly cleaned area....DON'T BOTHER STICKING IT TO THE BARE WOOD....YOU HAVE TOO MUCH SUPER GLUE ON IT!

When you have the patch completely sealed on the existing monocote, take your heat gun, and shrink the wrinkles out of the Monocote...shrink it to the wood parts!!! IT'S JUST THAT EASY!!!!

Remember....it's a Profile...they can't see the patch from 10 feet away!!!

Your flame out problem was probably a too lean setting....open that needle up a quarter turn. NEVER MIND......I JUST LOOKED AT YOUR PICTURE AGAIN....

Your problem is those zippy ties on the fuel tank, and NO insulation underneath it!!!!! Remove the tank, and take those zippy ties and toss em in the trash.

Get a slice of EPP foam, and a wire cote hanger. Bend the hanger so that it goes through the zippy holes, and put a hook on each end. Place the EPP foam under the tank, and use rubber bands to hold it together. Remember, it DOES NOT have to be held on like super glue....just snug enough to stay there!!!

I guarantee the tank bubbles, and flame outs will magically disappear!!!

GOOD LUCK

thanks for the info. mine only tends to happen towards the end of the day, i can set it up when i get to the field around 2pm and by 8:30pm it will start acting up. think alot of it is from me just not wanting to mess with it lol. but i think im going to go ahead and do what you was saying jsut for the added insurance and piece of mind that the next time it happens is because of me lol

It really isn't all that hard. A glow engine will run all season long with nothing but minor adjustments. Once I get the needle set on my glow engines it's usualy set it and forget it for the day.
1. Start the engine.
2. Lean to max rpm at wide open throttle (wot)
3. Point the nose straight up at wot and OPEN needle to get rid of the lean out sag.
4. Then put the plane back down and OPEN the needle 1 or 2 more clicks ( not 1/4 turn thats way too much)
RCM119 Made a good piont on insulating the tank from vibration.

Gas engines have there "carb" issues too, as well as ignition noise interference concerns. There's no free lunch if it's a IC engine there will always be adjustments that have to be made.

I think RCManiac119 hit on the problem. It looks as though you have soaked the piece of wood with CA. You will have great difficulty sticking monocote to CA.

You should look into the Tetherite LG from OMP. It is much more durable than the alum gear.

Default RE: covering problem

The most common problem when preparing an area to cover is to touch it with your skin. Don't ever use your hand to wipe an area clean. The oils from your skin will prevent the covering from sticking properly.

I use a compressor and nozzle to blow all dust off from any area that is ready to cover. This is followed by a wipe with clean paper towel wet with acetone. Don't smoke or have any source of fire when using acetone or you will have an exciting event!

Even poor adhesive Moneycote will stick well if this is done.

I also wipe any areas where overlapping covering needs to be applied before the next piece goes on with some acetone. The covering will stick to the other layer so well that it is almost impossible to pull it back off.

The secret for good adhesion is to be dust free and no oils.

This is my experience.
