Title: Engine "reconditioning" tips?


Mike - April 25, 2005 02:51 PM (GMT)
I'm wondering if anyone on this board will even remember me. I'm guessing Alvin will. After all, I have crashed one of his planes for him. B)

I started flying with ACMA about 11 years ago, worked at HobbyTown for about 3 years, and I stopped flying about 7 years ago when I left Mobile for Auburn. I've been back in town 3 years now and am getting the bug to get my gear together and come back out to fly.

My question is, what kinds of things need to be done for an engine(s) that haven't run in 7 years? I've got a couple of Webras (.32 and .50) and a YS .45 that would quickly find their ways back into a few planes and I just hope the engines don't have a shelf life when they aren't run for this long.

I guess the same question goes for my electronics. Do these Futaba receivers and batteries have a shelf life that I should know of? (wrong forum, I know)

In any case I hope to see you guys soon.

Hi Mike,
You still tooling around in that Mustang convertable?

Great to hear from you and that you might get back to flying. And yeah, you did crash my airplane and I made you fix it, huh. :P

Engines:
Unless they have rusted up some on the inside, should be ready to run again.
Clean them up if needed, put some oil down the carb intake and flip the prop over a few times. If nothing is grinding and you feel some compression, should run again.

Radios:
Batteries might need replacement or might not.
Charge them up and see if they come up to proper voltage.
Run them down and charge up again.
Check voltage under load and play with the system on the bench to get an idea of how long they will work.
Or, if you have a battery checker/cycler device, use that on them.

We will be looking forward to seeing you at field all ready to show us some neat moves. :newstuff:

Hi Mike, Hmmmmm Batteries setting around for seven years.I don't think that I would take a chance with them :thumbdown: It ain't worth crashing a plane over :plane_crash: On the engines, What Alviv said :thumbup:

Hi Mike

Whats up dud!!!
Guess where I'm working now! HobbyTown USA. Need a Job? :dance:

Take that engine and remove the high end needle and run some new fuel in it to flush it out. Put some oil in it and flip the prop over a few times like Alvin said.

Trash the batterys..... :P :P

Ah, I knew a few folks would remember me.

No more Mustang Alvin, I had a temporary lapse where I thought I needed to have a more "practical" car and bought an SUV. Then a month or so later I got bored and added another convertible to the garage anyway. At least the SUV will tote the planes around nicely.

Andy, how long have you been working with Rob? I need to get up there and see what's new around here. Plus I think I left 2 planes hanging for sale about 5 or 6 years ago. :lol:

What kind of oil is best to run through these guys? That oughtta show you how long I've been out of the game, huh? I'll swing up by the shop one of these days and pick up a fresh gallon of fuel and see if I can't get these things to fire up. What's a gallon of Cool Power 15% running these days, about 40 bucks? :D

Hi, Mike,

You may have to replace the diaphragm, o-rings and gaskets in that YS .45. All parts come in a replacement kit. Check with HobbyTown, they can order it.

Careful with those batteries. Make sure they are in good shape before using!

Welcome back!

A gallon of 15% coolpower costs $14.99 or $16.11 with tax.

And the Hobby Town fuel is a buck cheaper.
