RE: ESM LA-7 From VQ Warbirds
[quote]ORIGINAL: aminklein I just received my LA-7.  It's a beutiful ARF.  The quality of the work and the paint are great.  Even the hardware is adequate.  With a great plane like this, however, I might upgrade some of it to be on the safe side.  I'm really happy with the plane (and the price).  Only the shipping from Troybuiltmodels was a bit of a disappointment at $143.  Troybuiltmodels carries a DLE 35RA (rear exhaust).  After studying the specs and dimensions, I believe that this might fit into the cowl (with the exception of the spark plug).  I'll take my time in assembling because I want it to be perfect.  No one could be disappointed with the plane.  Art M [/quote] Be sure to use incidence meters on the wing, horizontal stab and thrust lines. I am flying my third EsM LA7 (I do like them) but all of them come out of the jig with a tendency to climb.....putting about 1 degree of positive incidence on the horizontal stab ( while keeping the wing at zero) levels this one out nicely

RE: Pica Spitfire 1/5 scale HELP!!
[quote]ORIGINAL: jetlag Sorry to revive this thread, but I am in the midst of repairing my 1/5 PICA Spitfire due to having tried to fly it tail-heavy. I have seen the cg listed here and elsewhere in this forum as between 3.5 and 5.5 inches from the center of the leading edge. My plan measurments show it to be about 4.5 inches, which has been seconded here. Is this the proper cg, guys? I guess I am looking for the proper consensus! Thanks in advance! Allen [/quote] I built and flew three Pica 1/5 Spits...first on CG.....I measured the distance between the leading edge and the trailing edge next to the cockpit. I calculated 18percent of the measurement and balanced it there...all three flew fine Second on landing gear placement...many want to cant them forward to prevent nose overs. You can do that but you end up with a funky, wrong look. I ended up relocating the main spar about 1/2 inch forward of its current location. This allowed the correct placement of the gear with the correct forward cant and the right look. If you do this, the plane will balance on the main axles. Yes, it will nose over if you are not careful but that is what the full size one did as well. Third on engine size, mine all came in around 20 lbs all up. I found a strong 1.8 moki or larger flew the plane with adequate authority Fourth is engine cooling....if it is enclosed, you need to use the 1:3 ratio.....otherwise dead stick landings due to lean runs The spit is a delight to fly and beautiful to boot....a bit tricky on the ground, though

RE: Vailly Aviation Hawker Hurricane Build Thread
[quote]ORIGINAL: DaddySam I compared the stab thickness from BT's plan (enlarged) to Roy's and it is virtually the same. I haven't heard any horror stories from folks who have been flying Brian's Hurricanes so I am thinking the bigger flaps on Roy's may be the culprit. When enlarged, the plans are very similar - the rib spacing on the wings is virtually identical. When it comes time for test flights I'll definitely start with flaps at about half available travel. Thanks for all your thoughts and ideas on this. Now I've got to cut about 70-80 flap ribs..... [/quote] Having flown my Vailly Hurricane with both full flaps and no flaps, I experienced identical "porpoising" on landing....I believe it has more to do with incidence than flaps...

RE: LA7 Info / Research / Build - Scale Wings
[quote]ORIGINAL: wxman2 One item I am trying to find is what material was the exhaust shield area made of; does anyone know? [/quote] The LA 7's contained much more duraluminum than the LA 5. They still had wood skinned wings and fuselage, however. The shields are duraluminum...not anything exotic like stainless steel. The Russian government calculated the combat life of these planes in weeks and built them in massive numbers so nothing exotic went into them. As for cooling the engines in our models, mimicking the way they did it in the full size plane is a good start....first off, the LA 7 did not have a fan despite some sources claiming they did. A close study of photos will depict cooling louvers used to control the amount of cold air entering the engine which was a considerable concern when dealing with -60 degree temps! We don't fly in -60 degree weather so we have to cool the engines....the best way is to start with a thin annular gap (distance between the edge of the spinner and the cowl lip) and create a sealed plenum chamber in front of the cylinders. This does two things: it slows the air down which causes the pressure to increase. Slow moving, high-pressure cool air is much more efficient at scrubbing heat from the cylinder fins than fast moving low pressure ram air. Next, make sure the exit area is three times the volume of the entry. Then, let the physics of fluid dynamics work its wonders! it works and can be seen in none other than the mighty air-cooled Reno Air Racers. Here is a cool link to how it works on the air racers although they do use ADI and spray bars as well but what do you expect when they are boosting the engines by twice their design! http://www.supercoolprops.com/articles/gwhite.php

RE: Vailly Aviation Hawker Hurricane Build Thread
[quote]ORIGINAL: DaddySam I've almost got the nerve up to cut the holes for the gear bearers but I'm doing some last minute checks. The problem is that there is no way I can bend the aluminum strut back 8.5 degrees to bring it back to the scale forward rake. The strut is about 3/4'' in diameter and I'm sure it would weaken it if I put it in a vise and hit it with a sledge hammer. So the decision I have to make is would I rather have a strut cover that is parallel to the tire when down or flush with the wing when up. The alternative is to increase the pintle angle which would put the strut forward when extended, perhaps by as much as an inch. That amount of rake forward would be noticeable, but I also suspect the strut cover would make it less noticeable. I suspect I will compromise and have some rake forward. As soon as I have decided on the cuts I'll post some pix. Sam [/quote] Daddy, Daryl at sierra makes rotating retracts for the vailly hurricane...they actually rotate back about 9 degrees as they retract solving the problem you are struggling with. I have them in my vailly hurricane (which is gathering dust in the rafters) and they work as advertised.

It hit at about an 80 degree angle and was probably doing 350mph. Nothing remotely resembling an aircraft remains. God's grace on those killed and the families that they left behind.

RE: LA7 Info / Research / Build - Scale Wings

Here is what I am going with so far: Scale Wings LA7 1:3.5 with all the accessories Moki 7 cylinder 250ccm when it comes out Have not picked a paint scheme yet; struggling with this since the paint schemes I really like are not scale. Now for a few questions, I have attached a few photos a LA7 aircraft and they look to have a fan like the FW190. 1. Does anyone know for sure this is a fan? 2. If it is, could a person use a fan made for a simular scale FW190; do you think it would look okay? The paint scheme I really like is Mick Burrells LA7: http://www.youtube.com/watch?v=xvRDltmAERA [/quote] Actually, it is not a fan. They are engine louvers and were designed to help keep the engine warm during the extremely cold Russian winters. The louvers would be slowly retracted as the engine warmed up allowing more cooling air into the plenum cowl. Overheating engines was not one of the primary problems encountered with the LA series...overheated pilots was a major problem, however. The firewalls threw off so much heat that the pilots often flew with the canopies open to keep cool. They also leaked a tremendous amount of carbon monoxide into the cockpits...another reason pilots flew with the canopies open

I am on my second LA7 and both required downthrust shimming...not surprising since they all come out of the same mold...on a different note, I am changing out my batteries from A123 to lipo's....the experiment proved that as cool as the A123 battery technology is...the capacity simply isn't enough for this airplane.

RE: Vailly Aviation Hawker Hurricane Build Thread
[quote]ORIGINAL: NA-73X DaddySam, I've been lurking around here watching this thread since it started. My Hurri was farther along than yours then and i've since finished it. I have 20 flights on it now and haven't broken so much as a prop. In my opinion, a lot of what is written about this bird is unnecessarily scary.  You just have to keep some power on through the landing approach. If it gets too slow the nose will drop abruptly. Elevator won't bring it back up, but power will. Use the flaps to keep the speed down, fly it on, then cut power. Mine shows no tendency to bounce, but I have only flown off grass. The plane is a pleasure to fly and viceless in every other flight regime. It is 27.0 lbs. with a G62 including 8 oz. in the nose. Sierra retracts. [/quote] Well, I think the best you can say about this plane is it has mixed results![8|] As I said, I have seen one fly and land on You Tube just fine and I have seen two (mine and my buddies) fail to flair. A third poster has described the same problem of failure to flair. NA-73X is having success...I'm not sure where that leaves anybody except "pay your money and take your chances" The Vailly Hurricane flies great in the air and mine tracks and takes off beautifully (much better than Spitfires) but the landing characteristic is a "deal-breaker" for me. Believe me, if I could figure out how to land this bird, I would be out flying it constantly.

RE: Vailly Aviation Hawker Hurricane Build Thread

I have a bundle of sticks in a box called a Valley Hurricane and it will be my next build. Sam encouraged me to buy it so I am studying his build. Any info would help all of us who admire this plane. Cheers Moggy [/quote] HI Daddy and Moggy reliving the past is always dangerous but I am willing to share all I can with you (and any others interested in this bird). First, Mine is already about 12 years old and has less than 10 flights since every flight resulted in a broken wing. Both my friend and I built one of these...he sold his after he tried unsuccessfully to land it and the buyer also sold it after similar results. Here is my take; my plane simply won't flare. No matter what speed I make the approach with, wheel or 3-point, the result is the same. The plane leaps back into the air between 6 and 10 feet necessitating a "go-round". I have checked the elevator travel and although certainly not a "3-D'er", it has enough throw to force the tail down during a typical flare. I have tried with and without flaps...same result. I have moved the CG forward and back within 1 inch of the original...same result...If I slow the approach way down, there is not enough energy to flare and the plane simply smashes into the ground tearing out the gear. I replaced the original gear with Sierra Giant vailly Hurricane gear...same result...I have given up and it hangs in the rafters...I don't intend to try to fly it again as I really am done repairing the wing. I strongly suspect an incidence issue...tail or wing but either way, it is too big to fix. I do recall building about 2 degrees of washout since I do that with all my warbirds and it is not a "snap-stall" but a refusal to flare I have seen a Vailly Hurricane on you tube land successfully so it can be done but my experience and my buddy's was not good with this bird Best of luck to all with this plane as it is a nice flier in the air

A123s are great but Lipo is still king when it comes to power and weight. I rebuilt all my A123s to RX packs and they are working great on my warbirds. [/quote] with throttle management, I can squeeze about 6 minutes tops... but you can bet the plane is circling the field when I am that far out on the timer. I understand about the Lipo's. I didn't want to worry about the over-charge, discharge, volatility and generally slow recharge times. Plus, I would have to design an easy-to-access hatch for removal of Lipo packs and I would have to haul around several packs to get several flights in at the field without burning up the entire day. The A123's allow me to re-charge the packs in the plane over the course of about 35 minutes so I can get a couple of flights every hour. I usually don't fly more than a couple of hours anyway so four flights works just fine for me.
