I did a search on "build" and "tape" and didn't find any complaints.

Thanks,

Tape works, but for added insurance, I run a thin bead of Elmer's Glue on the foam before slipping it under the plastic guide. Just wipe any excess off with your finger and it drys clear. Very easy to break loose, just run a razor blade between the foam and plastic to "cut the glue". Takes about 8 seconds total to remove the horizontal tail.

Thanks for the tip.

Flew the ol' Jug today... was a notably calm day. Every time I fly it, it builds more confidence. Did a low pass inverted over the runway about chest high today. Was a first for me, felt great, no drama, able to just roll 'er back over and climb out at the end. What a great plane. Did a slow-and-dirty fly-by upright with gear down and full flaps a couple of times, and a couple of fast passes too, with the Extra 300 prop and G25 motor singing along... a couple of straight axial rolls up high, then some snap rolls, and finally a big air gobbling large loop. Ended it all up with the usual greased P47 landing. I nosed over during taxi due to tail wind, so once I get that one little part wrung out, it's all gravy from there!

Just as taxiing into the wind requires up elevator, taxiing with a tailwind requires down elevator.

I've heard that, and it makes perfect sense... just haven't made myself do it yet. When I mention it at our field people look at me like I'm crazy -- I think they just 'race' down the taxiway to keep the tail down with up elevator both directions!

Next time we have strong winds, I'm going to play around with down elevator on the downwind taxi.

I maidened my mostly stock Parkzone P-47 this morning. I got up bright and early so the winds would be lite an I would have the park all to myself. Took off from the dirt baseball diamond and she was airborne in less than 20 feet. Had a great 6 minute flight. She felt real good in the air. Needed just a little bit of left aileron trim to fly straight and level. I landed without flaps back on the diamond.

Put in a fresh battery and took off again. Never went beyond 3/4 throttle. After another great 6 minute flight I brought her in for another easy landing without flaps.

I can't wait to get back out again. I'm waiting for a set of retracts to arrive. The weather here is supposed to be crappy until the weekend so my next flight may have to wait until Sunday.

This is the way you do it in full scale. When the wind is at the back on a tail wheel plane you hold forward on the stick. You also should be using the ailerons to keep the upwind wing down in crosswind as well.

There is a catch at this scale though. The tail is so light and there is so much prop wash that you may nose over anyways. On pavement you'll probably be safe but on grass even doing everything correct with a moderate tail wind you WILL nose over.

Another good trick is.. If you trim your Throttle up to a idle, the plane will always have a hair of forward momentum, but it also has a slowing Affect.. I always run a idle on my electric planes, its softer on the equipment, and it mimics a gasser..

You can see me set the idle in this video, and how much it helps the landing! I don't even Use the flaps.

Idle is not a bad idea. It is easier on the ESC in my opinion too because when the motor windmills(diving throttle off) it is generating electricity that is going back into the ESC giving the FET board a ripple effect in reverse.

^^ if there was a way to harness that windmill effect to recharge the battery.....I took many electrical classes so I know and it bugs me...But remember! If you by chance hit LVC at idle, You can't shut down the motor to reset the Esc....

Many of wind generators are converting to AC. basically a reversed variable frequency drive...

Bingo. For 1:1 or even larger scale model aircraft where the speed can be well-regulated to remain below the prevailing windspeed, I'll bet it works a treat.

Today we were favored with winds gusting to 20mph, and after flying my other planes I thought -- "Hey, I have the P47, why not try the downwind taxi elevator technique?"

So I did a normal into-the-wind take off, and flew a normal flight, with the Jug handling the wind with not much problem at all. My landing was fortunate in that the gusts steadied up to about 12-15 just long enough for me to grease the landing. So I am ready to turn it around, and I got it just headed downwind, and held down elevator. I'd say the technique works... for about two or three feet. At that point, my ability to regulate ground speed, combined with the chunky nature of the grass field and the changable nature of the wind, made me nose over anyway.

So at the end of the day, with our very light park-sized models, flying off of our rough field, it seems the most workable solution is to do what most others with experience out there have advised me: just give up on trying to keep it to a scale speed for the downwind ground handling, and instead be sure to taxi fast enough so that up elevator works in all directions, for whatever wind you have that day.

Since you are taxiing downwind, you can go pretty fast in a strong tailwind, without generating appreciable main wing lift to worry about.

So I just got my new p-47 today and was wondering if anyone is using a four blade prop on just the stock 3 s set up. I see a lot on here four the 4 s setup. If so what kind of prop are you using and where can I get some? Thanks for any input.
