Hi my friend, This is my suguestion on repairing your plane. Ist. cut off the broaken motor rails even with the bulkhead (use a razor saw). 2nd. Buy a motor mount to fit your engine. 3rd. Locate your motor mount/mark and position on the firewall. drill bolt locations and install 4-40 blind nuts. 4th. Install motor mounts. (use hex cap screws and blue locktight) 5th. Install motor on mount making sure that you have prop clearence on the cowel. Note: If unable to install blind-nuts for some reason, use wood screws to attach your motor mount to the fire wall. Make sure that you remove the screws after installing the motor mount and use thin ca on the screw holes to harden them, then re-install your motor mount. Good Luck >>>-> Bill

hi    thanks for the clear nail polish idea-to hold down the covering-   i would just like to ad-always use alcohol or K2R cleaning spray to remove and clean any fuel soaked area- a coating of  sigs clear dope -is old school and will also seal fuel soaked balsa -and make it a hard surface again-  to prevent fuel soaking to begin with-be sure all surfaces are protected at the time the plane is completed-you can seal seams and decals on heat shrink coverings before the fuel soaking gets started   that way- you will not even see the clear dope on the seams once it dries

hi  for fuel soaked balsa-  clean with alcohol- always  -if real bad apply K2r  dry cleaning  spraypull the oil out -get at most super markets- use sig clear dope -it will fuel proof the balsa and make it hard again-best way to bring it backuse sig clear dope under any area-that you know will be exposed to fuel-like the ailerons behind the engine exhaust-before you apply you shrink covering-covering will stick to clear dopeuse clear dope on all covering seems and decals to keep them on -when it dries you will not see it on shrink coverings-covering will no longer lift at the seems

Saturate the area with K2R and let it set for a couple of days. Yes, it works very well. I have used it for years. Afterwards, brush or vacuum it off completely then seal with dope, epoxy, polyurethane, or whatever you like.

ORIGINAL: davebart

This may be a new post but fits here. I am new to RC. On a couple of my planes, the covering is peeling along the edges and where it wraps over the edge of the wing. I had ironed it but now the ironing does no good since glow fuel and other contaminants prevent it from sticking down again. Is there any easy fix for this. I know that it is a common problem, it just has to be....

Thanks, Dave
After 30 years of RC, I have finally gotten to the point when my airplanes last for years. I haven't stuffed a model in forever as a result of my brain to thumb connection...

In those 30 years, I have built some beautiful creations that flew so well, but were retired because of the oil creeping into every crevice it can. It's painful to junk a fantastic plane because it's fuel soaked!

In the recent year, it has been a deliberate move to abandon glow and use only electrics to escape the the threat to my models' integrity. I've spent a lot of cash switching to the new power systems. Some of the money has been wasted buying wrong stuff for applications, some has paid off brilliantly, and the future expenditures will be placed more wisely (learning... the hard way).

This winter is dedicated to surviving Nebraska blizzards in the shop building a fleet of models applying electrics to them. The advantages of electrics are huge. The airframes don't have to be built to withstand the vibrations, don't have to be coated in fuel proof goo and glue, and the noses can be made so much more streamlined.

My advice... convert to electric ASAP and never look back.

Hi!
Problem is...electric motors are so boringly easy to handle. They do not take any (very little) knowlage to handle and run. I take pride in knowing how to handle my glow/petrol engines and second: There is no real sound or smell.

Get some Sig clear Buytrate dope ,at the hobby shop ,and seal the seams and decals ,by brushing it on
You can use it under and above any film covering
You will not see it once it dries ,and that is very fast
Good to fuel proof a lot of stuff
Building a lot of RC airlplane kits ,for 30 years

Glad you found the aspect of the hobby you enjoy
For me my power plant will always be two cycle glo
I love the sound ,especially the smell of glo fuel and its the way i started in the late 1950 s
How often can you run an engine ,on Dragster fuel
The power output of these engines ,for there size ,is just amazing to me
The SOUND is a big part of my flying enjoyment

All due respect but i really dislike fussing with batteries , especially lipos
i refuse to put my home ,family and car , at the risk of burning to the ground , for a hobby
Do be carefull , you may be playing with fire
Two people at my flying field burnt down there homes and another his car
This stuff is just not for me
i am not fond of a fast projectile coming at me , without making much sound ,as that just seems like a dangerous thing to have happen to any person at the field
i am actually uneasy when electrics are in the air for the reason above
We agree ,to disagree , on our choice of power plants ,but the hobby does offer many options to enjoy

Wow is all I can , I flow glow , gas and electric and if you burn your home down in this day and age and your experienced at RC and can read virtually anything in the free world then shame on you.
Lipos as are dangerous as nitro fuel , a gas can and a eletrical board that can easily spark when incerting a plug.
You charge lipos under total supervision, you simply learn to multitask if you don't have the patience to sit and watch and charge and also charge at the field. If you crash a plane you need to examine the battery if it has puffed or has any signs of duress then you need to dispose of the battery, that is life with electric power.
Lipo fires are real and so is the danger of anything that is not taken seriously.
