Thank's DJ, not only is it a colorful scheme, but the PC covering
really makes it look like a fiberglass model. It looks good on the
ground too!

Foo, if you are using those HK servos for your retracts, they should
really be OK as they are metal gear and provide torque from 50 - 60
oz. in.

Pav, if I remeber correctly, RCLanders already stated that the 3575kv 4s motor will not holdup to 5s use...instead use a higher c rating lipo...i compared a 4s 4000mah 25c to a 4s 4000mah 45c the difference in thrust is amazing...i would guess another 15mph or more in top speed...happy flyn... DJ
thanks for the heads up on the C rating buddy. I currently have 2 nano-tech 4000mah 25c/50c and a 3000mah 40c/50c both 4s
haven't start the built yet since HK lost my parcel with the metal gear servos that I want for retracts

personally I like the nano techs.. they give significan power increase to my projects but so far I had the 45c ones.

electric retract system and I set my ESC timing to High as suggested
by Lander. With this setup, I can ROG in just about 30 yards or so, with
no problems at all. Each of the Lander EDF units has a recommended
timing setting in order to get the most efficient power. Hope this helps.
what's the timing setting for the 3575kv papa? where can I find this? ofcourse I got the 3600kv fury fan but they are exactly the same.
btw what's the PC covering??? mine looks real nice but are we talking about a film here or the paint layer that the foam has.. on mine you can' tsee that there is any foam there either.

don't know about him but mine are the base ones and I'm seriously considering on getting the other ones.. I know that the metal will surely work better but if the base ones are stromng enough to hold it I will have no problem using them... this is my first rc lander plane and I know that the constructino quality is way better tHAN other brands...

the closest to this brand amongst the chinese brands is the lxmodels despite that they are made of EPS...

well, imo, the base models are useless, way more headache than they are worth. even on a eps version built light at 40oz auw we just locked them down, no servos , and ended up filling the plastic parts with epoxy. flew great with fixed gear, the new one in the box will have servoless retracts of some kind.

thats up to you! i just would not waist time or money on the base units. replace them or fix them down, yank the servos and fly light. a lot depends on what you are starting with. if its more the high end then it would call for good retracts. in my case i bought a $99 eps a/f and built a cheapy with the fixed retracts . my guess is the servoless retracts will come of age soon , becoming both cheap and strong.

well Im waiting for a replacement on my lost parcel by hk which included the metal gear servos that are meant to go on the retracts..
Will those retracts bent? or collapse??? is it the locking thing that's the problem or bending will cause problems on closing?

Pav,

First, the Lander PC covering is a Poly Carbonate surface applied to the
EPS foam airframe. It is exactly like the covering on any typical bicycle
safety helmit. It makes the Lander airframes much stronger and look
just like fiberglass.

With my PC Panther, I removed the mechanical retract system (servos
& linkage) and installed the Lander electric retract system with the new
metal struts, made for the Lander Panther & Cougar. I am now convinced
that electric retracts are the way to go.

Now, regarding the recommended set up for the lander EDF metal units,
here is the link for the complete list;
http://www.nitroplanes.com/lealalel76du.htm If you scroll down
to the bottom of the page, you will find the stats for your 3575kv unit.
Let me know if this helps.

thanks for the timing thing.. ofcourse my 60amp plush ESC was working fine with that EDF unit. I had it in my F-22 but it was too tail heavy so I replaced it with a much more powerfull HET6904 + The Beast by Hoffman magnetics.

back to the retracts.. I know that the electrical are the best choice but due to money issue and beacaue I already ordered the metal sercos and the rate reducer to make the m look more realistic will these http://www.sonicelectric.com/Merchan...ategory_Code=W work fine... actually this is the page the actuallink is this one here http://www.sonicelectric.com/Merchan...roduct_Count=1


And another thing.. where can I find those covers to make gear doors?

sorry for being a bit persistent but I Think that's the plane that i'm going to love more than my F-22 I want it to be as right as possible

Pav,

The Lander metal mechanical retracts that you plan to use will be
just fine for your Panther. BTW, they are the same metal struts
as on the electric retract system. Just make sure that you reinforce
the gear attachment mounting positions for your retracts. I used
an extra layer of epoxy on and around the little plywood strips that
come with the kit. Then I coated each plywood strip with thin CA
which made them very strong.

Shipping costs are getting to be very costly everwhere, especially
now that we all have such a GLOBAL economy.

The gear covers came with my PC Panther. The nose had a set of
doors so when the nose gear was retracted, the doors closed and
completely covered the opening. I just cut the plastic (styrene)
doors down to make the frame that you see in the photo. Most
hobby shops or craft shops, have thin styrene plastic sheets that
you could use to make your own retract doors or covers.

i think mg servos are a must for retracts on planes of this size.

as far as will they bend ect., yes ,yes and yes. they might work on a 1-1 1/2 pounder, but not on this one!!
