Soak them in warm water for a few minutes. The cardboard comes off very easily then. I know it sounds wrong, but everyone does it. Very easy.

I usually rip off as much cardboard as possible first and then give the cells the bath. That way, you end up with less mushy cardboard.

Hope that helps,

Helps a lot. I was soaking them in alcohol. I have never had cells that had voltage like this. My cells are showing 1.3 volts!!!!!
amazing!!!!!

It was taking me 10 minutes to scrape the first few cells clean, with hot warter and alchohol it's taking me about 20 seconds!!!! Great!!!

Finally, building this thing...

My mini Graphite came without instructions, and I have done my research so I am going to post my pictures and construction in this thread. First bit of construction on this plane is fixing the poor flap deflections. The common trick has been to drill into the wiper blade and insert the brass clevis into the wiper and reinforce it. Here is how I did it...

Drill the wiper with a 3/32 drill bit. And then with a little coaxing the brass clevis will screw right in...

Here is a shot of the "mix" being applied inside the wiper and surrounding the brass clevis. I did a mix of:

3 hour epoxy (with a bit extra hardner)
lots of microballons (for that light airy feel)
a bit of milled glass (for strength)

This is how I will leave it for tonight, I will take better pics tomorrow...

The instructions, I received, recommend a hard balsa block/strip must be glued in, with a tight fit, between the front of the wing servos and the main spar - I assume this is to prevent flexing of the top skin / flutter. Looking at your pics I see you have used the Volz alum. mounts - I used the plastic Volz servo mounts available from Hoellin - our mounts obviously spread the load over a bigger area and in addition I have an extra layer of glass on the inside of the upper skin (also in the instructions) - I was wondering if the hard balsa block is needed although, t is not a big job to add it!

Some of the guys on this site used the factory fitted holes for the flap horns. I will be sport flying - do I need the full 80 degree deflections to land on a fairly small field ?

MG flaps

rorywquin,

for reference check the video on this thread (address is posted by me on Sep 23, 2003).

There you can see my MG landing with about 40 degrees of flaps. It is quite ok, but I am still planning to modify it for 80 degrees in order to get better control while landing in small fields.

I guess we all have our ideas on flaps on the M-G (and other planes) but I find the M-G will land on a postage stamp without any flap mods. I've noticed a lot of folks who have extreme flap extentions seem to have servo problems a lot more often than the norm. To each his own.

I intend to try the original position for the flap horn - we land Lift OFFs (admittedly lightly loaded), Fuegos etc with no problems on our field and it is SMALL!

If it does not work I will change the horn position !1

rorywquin,

I had Fuego and have currently Lift Off. I feel that my MG even with "original flaps" is much easier to land to small field than Lift Off. My Lift Off and MG are both quite heavy 2,4 and 2,5 kg.

These servo problems are they do to the increased deflection or to the amount of force required to hold the flap in the extreme positions?

Well this is the case if you do have a field which don't have
high obstacles. However it is not possible to have a steep approach at reasonable airspeed with flaps 30 - 40 degrees.
When flaps are set to 80 degrees, its possible to start a steep approach after high obstacle is behind plane and still make the landing without hitting the end of landing area.
