Hey everyone, long time no type! I have P47s ranging from the Nine Eagles 400mm up to the big V.2 FMS, and as far as I'm concerned, they ALL fly good, but they also have their own unique little quirks. My favorite of mine is my old, well worn 750mm FMS. Currently running the V.2 4 blade prop on mine with the stock power section, added flaps last year, and that old bird is probably the best flier in the P47s we have, with the P.Z. a close second. My most recent P47 is my 980mm FMS Razorback, which, again, doesn't really have any bad tendencies worth mentioning...

Default Eflite P47d ?

Hey ya'll

I purchased one of these. It flies beautiful. I had 6 flights on it & the wing seemed loose. I snugged down the wing securing bolts (were slightly loose) the whole insert in wing slid down into wing ! They were glued so lightly , I couldn't believe it. I further checked other glue points, very sparsely glued ! I own A PARKZONE 300S 3D PLANE also it has the same motor 950 kv - 30 amp esc. This set up burnt out the esc in 2 flights on the extra 300. It was pulling 35 amps stock ! Horizon provided me with a 40 amp esc- now no problem - excluding the famous wing design flaw. The p47 draws 34-36 amps with 3300 mah 30c battery -2 blade prop. Has anyone burned an esc yet? How about the as3x fuction- is there a need to change anything in it from the factory ?
Any replies appreciated.

Bob

Old post, but I have the PZ P-47 and now two FMS P-47s Both are great fliers, each has its own charaterisitcs, but I really like both. THe FMS is much more scale like and I think a better value for the money.

I just picked up the older pz p47 , I know this is an old thread but didn't feel I needed to start a new one , I'm having a few issues with my cog , the plane came with no retract or flaps ,
flew it a few times with stock 30amp and 480kv like my Trojan has , even the same prop as Trojan, I was struggling to take off on my short runway but got it up .
then I added flaps ( 13g servos, all the parts were there already) the previous owner had 21g of weight on the rear of fuse which I removed .
next flight was even harder to lift off and was bobbing up and down with horrible cog , I figured removing the weight and adding servos caused the forward dipping issue , so I moved battery back 1.5" and cranked my elevator travel to 150% , didnt seem to help ,flew my trojan right after and it takes off within 10ft , I know it's a different plane but there's gotta be a solution .
I just added the 21g of weight again and 14g more ,
hoping this will get me up faster and in a shorter distance .
is there a specific way to measure or adjust cog ?or a tool ?
I didn't use the flaps on take off because I figured itd slow me down more,
I also just added a 1250kv motor since I couldn't fly today , and considering my pz 3 blade prop , but I want to try the weight / motor upgrade 1st before I risk wrecking my prop
any ideas or tips would be great ,

the plane is a bit worn out but flew ok besides the obvious cog problem

Should have a CG point on plans or instructions, but generally 25% of mean aerodynamic chord from leading edge. Full flaps would result in a drag penalty on take off, but just one notch (if possible) should result in increase of lift with min. drag. I make up a stand with 1/4 " dowels and plastic tips to balance at the proper point.
Hope this helps, that's a nice looking bird.

had a flawless fight this morning , everything felt right, 0km winds , every take off and landing was smooth , gained a lot of confidence in my flying skills , couldn't be happier.
learned my flight time range at different throttle levels and even got some long inverted practice . dead calm winds really makes a foamy fly scale.

I just built up my parts plane last night, all it needed was a motor mount and some servos , doesn't have landing gear so it's gna be a belly lander , I'm a little concerned about the cowl and ailerion servos , does anyone fly these all belly landers or am I going to break stuff every time I land it?
I do have the clear skid plastics installed , but with the servo arms exposed I can't see them taking too many hits plus longer grass might hook up on them ?

I was going to build some kind of protection but not sure it's worth it

HH still sells the belly tape kit made specifically for this bird. That's about all you would need for belly-flopping it.

The little UMX razorback P-47 flies great on 3S 200 mah. Lively and predictable, even does well in a little wind. Recommend modding to make the top fuselage section into a battery access hatch with a few small magnets. Worth the effort, IMHO. Stuffing a battery into the belly slot works, but seems a bit crude to me.
