Status: offline 		Hi all,

final report on the P-40 as well. Just a stupid nervous move, was turning to initiate landing, reduced throttle too much, wasn't able to raise the plane and crashed in a tree.

Fortunately the engine and electronic parts were OK. I really like this model and had spend many hours to make it perfect.

Maybe that I was too attached to it?

Now flying a Funtana 90 with great pleasure and got an H9 AT-6 Texan built. But I know that I will get the P-40 again...one day...

Status: offline 		Ditto with other people's comments. Very enjoyable to fly, nice behaviour. Although I probably need to admit that my flying skills were a little bit under the mark and I may have been too nervous at the time.

My R/C experience is fairly recent; I started back in January and began with Parkflyers (PZ J3-Cub, GWS Slow stick, Potensky Eagle) then assembled a wonderful Training ARF kit from Germany (Multiplex Magister) and became comfortable with basic routines. Then joined my local WIMAC club.

I then decided to move on to glow fuel because I wanted more flying time. The P-40 was my first .90 plane and my first glow powered airplane (other than the line-controlled Cox P-40 that I once had when I was a kid).

That Friday, on July 22nd, I was flying the P-40 around when one of the club instructors recommended that I land from the East side of the runway. I was less comfortable doing this because we have many trees close to the end of the runway.

I blame myself for responding to this inquiry. Landing on the other side (with back wind) would have saved the plane I'm sure. Probably would have taxied too much and stalled in the grass...

But this is hard earned experience. A week later, when I came back with my brand new Funtana 90, I was determined to focus on flying and not let other people's comments or conversation distract me... my runs were excellent since then and I never had problems to take off and land, mind you this is a totally different aircraft.




Once I gain experience with the Funtana and the AT-6, I will probably be ready for this War bird.

Unless you have an experienced, trusted flight buddy whose opinion is usually sound, shut them off. And remember don't stop flying the plane until the plane stops flying!

Status: offline 		Got the JR791 retract servo installed, dropped right in. What a nice servo. Nice and slow and gobs of power. Did some flying off pavement this time and had a few minor issues with it rolling straight. Figured that out at home later on. There is some play in the struts that allow it to move up and down about 1/32" or so which also affects wheel alignment slightly. When the gear is down and sitting on the ground, there is interferance between the locked down adjusting screw and the top of the strut. You would normally not see the problem becasue as soon as you take off and the struts slide down, just enough to clear the adjusting screw. But if you have the plane upside down in a craddle it jams when you retract the gear and the strut hangs out a few inches. I fixed it by placing a plastic washer between the collar and the retract to keep the strut down. You could also do the same thing by adjusting the 2nd wheel collar down a bit but you would have problems when landing. The wheel collar would eventually move and you might get the jamming again. I had the jam happen once while flying. Now my retracts are adjusted nice and tight with no wobble. Still have to land soft but the toe in is right and it rolls straight now.
Getting comfortable with the flying. I'm noticing a little tail waggle on high speed passes like a corsair. Anybody else seeing this?

Status: offline 		Not trying to be a jerk here,

But it sounds as if it might be a good idea to practice approaches from BOTH directions.

You should be equally comfortable making turns to the left or right on both sides.

I have seen too many RC pilots that get locked into a bad approach only because they never
PRACTICED turning the "other" direction.

I am guessing that this is what the Instructor was trying to get you to do.

Practice flying a figure 8 pattern with a left turn away from you on the right side
and a right turn away from you on the left side. This will help to gain some confidence.

When you are comfortable with this then make the figure 8 so that you are lining up approaches
on the runway from both ends. Do this only when you dont have a bunch of planes in the pattern
so as to avoid a conflict with planes coming in on the standard pattern at that time.

Once you have gained proficiency with this you should be able to make the
right decision at the right time for getting your plane back to the runway from almost any situation.



Good Luck

For sure the instructor didn't mean no harm, I put the responsability on my shoulders as I should have said that I wanted to land in the West direction to avoid any additional stress.

I practiced landing and taking off in both directions with my Magistor Trainer plane and it worked well; however the Warhawk has very nice camouflage tones for war purposes...in the context or RC airplanes, it is difficult to see the airplane in cloudy conditions and this was the case when I crashed. The cloudy conditions and the fact that I felt less comfortable coming from the East side of the runway, where a lot of big trees get into way, were the main ingredients along with the nervosity.

Point well taken!

Received my replacement struts from GP - had to do some minor mods but nothing hard. Did not like the shinny struts so cut two 6 mm plastic drinking straws to size - coat of grey paint and slipped them over the struts - looks great and works great.

Status: offline 		I cleaned it with alcohol, then sprayed it with a polyurethane spray from a can. The 20/20 fuel I use eats it up on the exhaust under the cowl but you can't see it on the bottom. Sure makes it look alot different flatted out.
BTW this plane will not slow down for me, she comes in and will not stop gliding. Perhaps it's just a little nose heavy. Don't think you could stall her very easily.

Status: offline 		Can someone please tell which Hitec retract servo can be used on the P-40 warhawk--HS 77 Low Profile BB or 75 BB retract servo?

Thanks!

Status: offline 		I believe the hs75 is the retract servo. The hs77 is a low profile aileron servo. The hs75 didnt work in my H9 P-40. The gears stripped. Was basically worthless. I did what others here have done and used the JR791 heavy duty retract servo. Night and day difference. It works without straining and is slower which makes it look nicer when retracting up in the air. Well, as nice as an arf with spindly struts can look. I costs more but I dont have any worries now. The hs75 was 92oz and the 791 is 260oz and metal geared.
