Status: offline 		Vahn, I read your reply and I have a question. I fly both gas and electric and for backyard flying, this easystar is a gas. I'm not however getting much airtime out of the 1100 mAh 7 cell sub C I use, certainly not the 25 min at 1/2 throttle you mentioned. What are you using? Maybe I'll switch over.

My friend has one of the new Multiplex Easy Gliders. It is made of the same Elapor foam as the Easy Star and some other Mulitplex planes.

In any case, I was flying it and put it into a tree. I dinged the leading
edge of one wing. Nothing too serious. A depression about the depth of half a
nickel with a small crack in the foam, maybe 1/2 inch deep. Foam was starting to return to shape after sitting about 10 minutes but not all the way back yet.

To restore this foam to shape I heard you pour boiling water over the foam, or dip it in boiling water and the foam returns to its original shape. Is that so? Have you tried it? How much boiling water? How long does it take to happen?

I would presume after you do this you get it all aligned, drizzle in some CA
and it all glues together good as new.

Tell me this is so! Please!

Status: offline 		I am a new owner of an EasyStar.
I have got one pack of battery Ni-Mh KAN 1050 mAh: (brand new)

I am looking for constructor DATA of these battery, in order not to distroy them at the first charge and to format them properly.

Who knows which cycles of charge-discharge is recommended to format these kind of battery before the first use at nominal power ?

Many thanks for you help. (Sorry for my poor language)

Regards.

I do that twice, then go to normal charge cycle which would be to charge them at about 1.5C. About 1.5 - 1.6 amps for those packs.

Status: offline 		Many thanks aeajr,

So first charge at 100 mAh during 20 Hours.
Then discharge at 6 A , corresponding to a 1/2 throttle setting: right or not ?
For me, by using a Graupner Ultra Duo 30 for the discharge at 6 A

Second charge at 100 mAh, and discharge at 6A

And first quick charge at 1.5 C.

Do you confirm my understanding ?

Thanks again for your help.

Regards.

You could do the first quick charge at 1C if you like. Ease it in, so to speak, Then just fly normally.

The discharges could be less than 1/2 throttle. I just recommend no more than 1/2.

Many cyclers discharge at 1, 2 or 3 amps. That is fine. Just takes a little longer.

FMA’s Balance Pro 2s Charger is part of a revolutionary new LiPo battery and charge system for R/C aircraft. In essence, it is very similar to the 2s Scorpion system for R/C cars. With a variable charge rate of 0.5amps to 10amps, the charger brings Balance Pro 2s packs to 90% of capacity in as little as 20 minutes. FMA’s Safe Charge Connector is a key part of the system. It enables the charger to monitor individual cells and independently charge each cell to its optimum level. Charge protection dramatically improves pack performance, pack life and charging safety. All Balance Pro packs from FMA come standard with the Safe Charge Connector. The Balance Pro charger may be used to charge only FMA's new Balance Pro 2S (7.4V) LiPo packs in capacities ranging from 1250 mAh to 6400 mAh.

At 7.4 volts, a single FMA BalancePro pack may be used in any application that requires a 2s Lithium pack for R/C aircraft. Further, you can place multiple BalancePro packs in series to obtain higher output voltages. Since the BalancePro charger can safely recharge a BalancePro pack at 3C (or 20 minutes), you can still charge three packs in the normal 60 minutes time of most other Lithium packs. Alternatively, you can use seperate BalancePro chargers to keep the pack charge time down to only 20 minutes.

The Multiplex Easystar from Hobby Lobby was easy upgraded to double the flight time over the stock 7-cell, 1100mAh NiMH pack using the BalancePro 2-cell, 2AH Lithium pack. The BalancePro provided slightly greater power than the stock pack and fit perfectly into the Easystar nose. I held it in place with a foam wedge.

To better facilitate the longer flights, I mounted my ESC so that the top surface obtained direct air cooling. The BalancePro pack never gets warm due to the low 8amp maximum current draw and the motor cooling is already built into the Easystar fuselage. This system provides 10-15 minute flights while keeping all the components cool to increase longevity.

Status: offline 		Hi all! I'm new to this site and new to RC flying in general. After much researching, I bought the Multiplex Easy Star, RTF. I love it. After correcting the channel 2 servo issue in which pulling back on the radio stick made the plane go down instead of up, I was able to successfully launch the plane. My first landing was rough - a stall at about 6 feet made the plane nose over into the field. NO DAMAGE! Adjusted the CG and launched again. After getting it trimmed, it glided nicely. A couple more landing mishaps before I had a smooth landing. A few more flights and a "touch and go" and I was feeling comfortable. Does anyone else notice that the Easy Star seems to drift to the right? I have some left trim which keeps it flying straight at center stick. Also, it seems more responsive turning to the left than to the right. More control is required and it takes longer to complete a right hand turn than left. Maybe my imagination, but maybe you guys might have some ideas. I've checked that the plane is balanced left to right. To keep the CG at the manual spec and the plane flyhing level, I have the 6 cell NIMH pack pretty far forward (almost to the nose) and a little down trim too. Does that seem normal? Times like this I wish my Dad, an eperienced RC builder and flyer, was closer so he could fly it and offer some suggestions.

Well, it's still in one piece and ready to go again. I love it!

Status: offline 		If you are using a around a 1000mah 2/3 A battery, it can loop at level flight at 1/2 power. You get 10 min flight times out of this pack. (not counting any time just sailing around)

You can fly inverted and even get the plane to do turns around the field inverted. Also will do loops, outside loops, stall turns.

A lot of the problem with the RTF kits is they put in a cheap 6 cell battery so you will not get close to max performance out of the easystar with this pack.

This plane beats the slowstick in that it handles a lot more wind, it's more durable and a better trainer for higher speed flight.

How many cells? This could be 6, 7 or 8 cell pack.
