SeattleFlyer, I dunno how I could explain it any more clearly. Working with plastic/polyester film covering is an art, not a science. The best way to learn is to get some opinions (which is what you're doing) and then just work with the stuff. There are many ways to get the desired results. You just have to find what works for YOU...


Ah thanks! I must have missed that post some how. I picked up an iron so I'll give it a shot. :D

For anyone interested,
The Ernst charge port will install on the other side of the fusalage just fine. There are no clearance issues at all and it just took a few minutes using the Dremel very carefully. The factory cut opening needs to be slightly routed larger. Be patient here and keep trial fitting, if you pay attention with the fit drilled holes will line up perfectly. This sounds harder than it is the total installation time was 5 minutes.

Good to know, thanks - my ernst should be arriving today..

I finally got to see this thing "in the flesh" yesterday at the field. The owner is not a beginner, I guess he bought it because he likes it. It was in trainer configuration except for the absence of the gear mounted speed brakes, and he had the flaps contolled by a servo. I was impressed by the landing gear design - very sturdy, and that sucker is not going to nose over. The 3 blade prop looks almost stubby, its so short. The ground handling appeared to be flawless and the lift off very slow and scale like. I was surprised at how slow this plane flies, and that it appears to be very solid even at slow speed. The landing was very trainer like, slow, good sink rate, no bad behavior. I guess my overall impression is that this is a very well behaved model. This sure looks looks like a well conceived package; I think Horizon hit a Home Run here.

I can see this as a first and second plane. The primary trainer can progress to a next level by replacing that trainer prop with a suitable 2 blade for a lot more power. Removing the wing droops with the additional power makes it a different airplane. I do believe I will be seeing a lot more of these at my field. There is a big WOW! factor with this "trainer".

Jim,
Thanks for your observations. Mine should be done Friday if I do not hit any more snags. Tried to mount the main landing gear yesterday and had some clearance issues. I wound up having to carefully Dremel the left wing slot wider to allow the gear wire to fully seat. The basic construction and repairs are finished and would estimate 10-12 hours at this point. I also have removed the speed brakes and let me ask you this, was the flight you observed flaps up or down? I too will use the droops for the maiden and have not decided yet whether to go with a 11X6 or 11X7 two blade prop. All that is left to do is final balance, clean up and run a couple of tanks on the ground to adjust the engine. I'll try and post some pics either tonight or tomorrow morning.



Casedit -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/21/2005 4:00:26 PM)

hey olstoney - you were right, a little dremel and the Ernst charge jack slipped right in the precut holes, great. I'm glad I didn't attempt the MPI switch on the other side as it would've required a lot of modifying. I'm almost getting ready to maiden mine as well, the only other mods i've done were removing the muffler baffle and retuning the motor, i'm leaving the air brakes and everything else in 'trainer' position. but was wondering why you are changing the prop ? is there reasons you heard of that are against the stock?

thanks



MMcConville -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/21/2005 4:22:40 PM)

I'd leave the stock prop on the airplane. Its an important part of the speed control. I'm also not really understanding the idea of removing the baffel in the muffler. The engine has plenty of power to fly the model if its running correctly, with the possible exception of flying at very high altitudes. If the power seems too low to fly the model, there is probably something else wrong.
Pulling the baffle will increase the noise level which isnt a good idea with flying fields being so hard to come by...



Ken Bryant -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/21/2005 4:31:55 PM)

I got to fly one of these in the full blown trainer config. It handled very slowly. Gee like a trainer... :) I of course tried to loop it and sure enough it couldn't loop. The plane handles very different than what I am used to even in a Trainer. It was real mushy.

The purpose of me flying it was to test fly it for a new guy. It flew and I told him it should handle ok for him. I would really like to see what this plane can do in it's full hard flight configuration.

thanks for the prop suggestion, it's useful info. as for the baffle, it's my experience on any motor that removing the baffle, which is basically just a governor will immediately improve the performance and only requires minimum if any retuning, it was a little louder but still a lot quieter than most models i see flying, i thought anyway. But the reason i removed it was because it seems the consensus has been it being a little underpowered, now i bought this plane because it's a trainer and im not trying to make it something it's not, but with such an easy mod like taking the baffle out - why not? what's wrong with a little more power EASY and for FREE [:D]



olstoney -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/21/2005 5:03:58 PM)

Casedit,
Don't worry about the prop a two blade in the right diameter and pitch will take care of any power concerns. I'm going to try the 11X7 Master Airscrew first after the engine is tuned properly. After some tach readings I'll know which way to go with the prop. There is hardly ever a thing as too much power, but learning how to manage that power is the key.

The parts that I paid for arrived from Horizon on Saturday. The droops that were going to be replaced at N/C and ordered at the same time still are not here and the replacement cowl through my selling dealer has not yet arrived. I'm beginning to feel S&%@ out of luck here. As soon a they arrive if ever, I'll refasten them with the tape that I had to purchase.

I really do not like being negative, as this really is a nice package, It's just too bad that I had to do all the work involved to fix the numeous factory boo boo's. That beind said, I can't wait to fly this and see what it can do in both trainer mode and without. I did remove those speed brakes though[:D]. I'll post some pics tomorrow after wifey helps me balance the plane in the morning.



rocknrube -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/21/2005 6:40:03 PM)

Hi Mike, What should the tach meter read when the plane is full throttle, roughly ? I ran my engine today and it transitioned perfectly from idle to full throttle without skipping a beat...and back down to idle perfectly. The tach meter reading I got was 1120rpm - 1125rpm (11250rpm) at full throttle and at idle about 200 - 300rpm (2000rpm)

It this okay for this type of Evo engine ?

Ruben



Jim Dines -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/21/2005 7:31:43 PM)

olstoney,

The flight I observed, he had a servo on the flaps. Had them up for flight and down for landing. He said he did one take off with flaps and one without and could not see any difference on the take offs. As for 2 blade prop selection, this is such a good slow flying design, I'de recommend 11X5 or 11X6.



ifixairplanes -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/21/2005 11:11:41 PM)

A guy showed up to the field with one these h9 stangs last weekend. He had me do the maiden flight. First flight was with speed brakes on and leading edge extenders on. Engine fired right up after a second of cranking and needed about 2 clicks for the high end to be right.
Lemme just say this plane flew GREAT! A little slow because of the extra things hanging off of it, but it flew great. Roll rate was tame for my taste, but I usually fly a cap with the rates maxxed out. I came in for a landing it the approach and decent rate are nice and easy. Hold 3 clicks of throttletill the threshold, cut to idle and flare, touchdown and your good.

All in all, I would not hesitate to train a pilot on this plane, as a matter of fact, I am goign to be training the owner come next weekend....

Jim,
Thanks for the input, I have an 11 X 7 MA installed and after the tach readings are in will decide where to go. An 11 X 6 APC is waiting in the wings if need be I'll just have to clearance the spinner some more. Pics will be forthcoming in the morning[:)].



Ferocious Frankie -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/22/2005 5:17:36 AM)

Any vids other than the one on the hangar-9 website?



olstoney -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/22/2005 1:37:17 PM)

O.K.,
Here's the pics I promised. Everything is done with the exception of reinstalling the droops and final balancing. For a size comparison, the engine box is from my 28% Precision Aerobatics Edge that is under construction and the cowl is from my Wildhare 25% Edge. The inside shot shows the installation of my Hitec gear, very straightforward. By the way the overcast sky is from Hurricane Rita that is 275 miles west of us, obviously no flying as we are still getting 20mph winds here. For any of you guys near the the projected path get the hell out. Been there, done that and got our t-shirts along with 25K in damage last year from Charlie.



Jim Dines -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/22/2005 3:55:40 PM)

Nice pics. Definately, a big WOW! factor here.



MMcConville -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/23/2005 3:33:21 PM)

Sure. Look on the web-site for the model here: http://www.hangar-9.com/PTS/Default.aspx




olstoney -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/23/2005 4:26:30 PM)

Mike,
What's the CG range on this airplane? Thanks....



MMcConville -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/23/2005 8:15:38 PM)

I really never came up with a range. It was designed so the natural CG (dry) as it comes ou of the box is good to go. The variances in mfg are limited to kep it within a good CG range.
Just keep everything where it is when it comes out of the box (which pretty much means dont move battery) and it will be good.

i'm pretty sure the manual stated +/- 1/4"



tr21triton -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/24/2005 3:49:49 AM)

the book said 4in. +/-1/4. i had to move my battery behind the crashpit/cockpit. when we put it on the balancer the nose went straight down.placed 3 1/2 oz between the tail bolts,but didn't want to add that so moved the batt instead.now it sits level on the balancer without even a finger on it.......



olstoney -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/24/2005 7:14:12 AM)

tr21triton,
Double check your manual, I think it is 4 1/2" plus or minus the 1/4". Can't balance mine until the replacement droops get here and are reinstalled. I'm betting on being tail heavy though after removing that rather heavy "flywheel" prop drive. The two blade prop is also substantially lighter that the three blade.



MMcConville -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/24/2005 5:59:41 PM)

It will not be out of a comfortable CG range as it comes out of the box. With built up tail feathers, and lite-ply fuselage sides, the weight variance from model to model can not be enough to cause a CG problem.



onblur -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/24/2005 6:24:53 PM)

I read through this entire thread, and I think I still have at least one question. Has anyone added the flap servo yet? if so, do you use a standard size servo? Is it just a bolt in affair, or is there any cutting and gluing?

I'm thinking about picking up one of these as a first gas plane. Actually, I had a gentle lady with an .049 on a power pod about 15 years ago, but i don't think that counts, since it had no throttle control. I have a few of the parkzone/hobbyzone electric planes, but I haven't stepped up to gas, because I couldn't come up with a good place to fly. Last week I found out that there is a club about 20 minutes from the house, so I checked it out thursday night, and now I definetly need a gas plane. This is looking like the one because it's cheap, easy to put together, able to do basic aerobatics, and you can buy replacement parts. I'd buy a standard trainer, but I don't want something I'll get bored with.
