KR> C.G. location / flying qualities

[Ross Evans]

Hi 
My kr2s empty is right on the forward limit. I have a 48 litre header tank. I 
will go over weight before I go out of C of G however in the worst possible 
loading scenario. Wings tanks with fuel baggage and a low header. The kr 
becomes less stable in pitch it will diverge for instance it will climb but as 
the speed bleeds off it will start to decend and as speed builds it will level 
off and then start to climb.
The KR will fly a couple of knots faster loaded aft C of G I have noticed it on 
a few long trips with good conditions.
cheers

KR> need more building info

[Ross Evans]

HI Dan I have looked at this idea to get rid of the top cable from the sling 
seat in case some one steps on it! If you have the new aerofoil the rear 
spar sits higher in the boat and the tube can run underneath I have a friend 
who is doing that and I noticed it when I was looking at his plane!
I wanted to get rid of that top cable and put a rod through to the back of 
the seat and have a bellcrank from there but I don't want to bore a whole 
through a spar so I won't! May be you could plate the area but I would want 
an engineers oppinion! Sorry I can't give you an answer!

KR> my aeroplane web site

[Ross Evans]

   HI dan I have own the mold for it and I have a guy that will build
   them using it! I may have to put blisters on it for the fuel injection
   rails to fit with out rubbing not sure yet! There is one cowl that is
   real good that my mate here in brisbane has done when I next go up I
   will get a photo! The cowl was designed to fit the 0200 and was set up
   to run a ellison throttle body on the bottom has the long inlet on the
   bottom!

   I am in Australia or I could get you one for cost! The guy that built
   on said it cost 400 dollars aussie getting it built by a mate in
   materials!

KR> Fuselage Glassing

[Ross Evans]

HI phil I have not glassed my boat sides bottom except I used tissue around 
the bottom corner "glass won't go around the tight radius and the edge of 
the ply after it is painted gets chipped and when moisture gets there it 
runs so I glassed it some people are putting a radius but be careful that 
you don't go to far as the main longeron there is very structural I would 
just mix up some micro balloons and fill the depressions and sand it ready 
for paint it does add a fair bit of weight glassing the lot!

KR>

[Ross Evans]

hi phil I could have purchased a 0200 with the project for about 12000 
dollars the engine had 1700 hours until over haul I spoke with the engine 
overhaul guys and between 20 and 25000 to zero time. The particular engine 
had been sitting for 6 years and to strip down and check it over would be 
about 3000 and if anything else was wrong more the engine ended up having 2 
cracked cyclinders and was not as the log book appeared a cyclinder is about 
1500 to buy! if the engine is certified a 100 hourly will cost about 1000 
dollars and it will use about 26 litres an hour! I straight away made my 
mind up of the risk that the engine could be a dud! and end up costing me a 
fortune! I am going to have more power and a much cheaper overhaul

KR>elevator mass balancing!!

[Ross Evans]

HI phil
I have put the tubing with the lead at the tips I am going to glass around 
the tube and over the elevator to past the hinge point as I thought that a 
twisting problem could arise!! I would guess that after the elevator is 
properly balanced the extra weight would be less than 750 grams I have also 
used mil fibre as it has good compressive strength under the glass as I have 
removed some foam at the attachment area. Yes I was worried about it being a 
problem and looked at the possible problems and I feel that it should not be 
to much of a problem I would have liked to have a linkage inside the boat 
but the aircraft was finished there when I got it! I beleive the original 
builder was looking to do the same as I am doing. I also wonder about the 
aeileron balancing arms they look a little week to me to!!!
cheers

KR>how is your kr going barry?

[Ross Evans]

HI Barry how are u how is your kr coming along?
I have been real busy on mine I expect the engine in about 2 weeks time it 
is currently getting put into a car to have the fuel injection mapped and 
then all the reduction drive and aero gear will be put on it! I am going 
real well on the building and am expecting the plane to fly around mid year. 
The canopy took about 250 hours to build and I have spent probably 400 since 
u last saw me!!

KR>elevator balancing marty roberts set up?

[Ross Evans]

HI netters I am currently building a kr2S I am looking to balance the 
elevator I have filled 2 10mm diameter lengths of chromolly tube with lead 
to the hinge point I am looking to attach it and have it looking like marty 
Roberts set up. The pictures of his are on last years gathering photo's I 
was looking to drill holes throught the timber of the elevator and put 2 
bolts with nylex nuts to attach it and then fill the tube with epoxy and 
mill fibre to give compressive strength and glass over the tube and onto the 
exsisting elevator is this what marty did! Most importantly is this the 
right way to do it! Any ideas would be great! on how to do it as I bought 
the project and other options of doing it would not be so fun and I want to 
fly soon!!
cheers

KR>elevator balancing!!

[Ross Evans]

hi guys thanks for the info I estimate the balancing weights with the arms 
glassed on to be around 1.4 kg and the computer for the fuel injection 
weighs 3 kg so I am working with that idea I have not yet got weight and 
balance figures yet but I feel from how the project is going I should get 
close with a far forward as possible weight and balance limit I have 
tricycle undercarrige also!! Time will tell drilling holes into the elevator 
to attact the arms is a concern and I only really want some bolts there to 
hold it while glassing I was going to use mill fibre around the area where 
the foam is removed and thought enough strength should be acheived! I was 
going to glass the whole length of the arm with about 2 inches of overlap 
onto the exsisting elevator!
cheers Ross

KR>aircraft performance how fast!

[Ross Evans]

HI Guys with regards to elevator balancing the guys that have bigger engines 
0200's what are the typical performance figures and fuel burn per hour. With 
out balancing the plans show no elevator balancing and vne is 200mph does 
flutter become apparent and with balancing does the vne increase as I 
suspect the vne has been set for this reason but I don't know for sure!

KR>aircraft performance how fast!

[Ross Evans]

hi Joe yeah that would be the case if the plane was past the forward limit
kr's that have been set towards the forward limit allow can be loaded better 
with out going out of balance but yes u are right! I have flown a kr2s in 
australia and the owner set his plane up and is can carry more fuel and 
weight and will remain in balance right up to MTOW which is the ideal 
situation I reckon the plane is still nimble and fun to fly right through 
the envelope! I beleive with tail dragger's they can fall on there nose with 
full fuel and no passengers on board. I am interested in what speeds 
aircraft are attaining with out mass balancing of the elevator as my 
elevator is built and what peoples oppions are as flutter can be destroy an 
aircraft inflight!
cheers

Ross

KR>elevator balance!

[Ross Evans]

HI guys thanks for the feed back! I have just asked the questions to get 
some oppions of other builders as I am no engineer and really want to fly 
and safely. I have been told by different fellows that elevator balancing is 
needed and have emphasised the need with more power but yes flutter can 
happen at any speed and I have seen some kr's that are flying with no 
balancing I am putting in a more powerful engine and have been told that 
flutter could be a problem at higher speeds that is why I have asked about 
the subject as I want to fly for a long time not a short stint. My plane had 
been built straight to the plans and was going to have an 0200 but they are 
quite a dear engine to get and overhaul so I looked around and got a little 
more power but I was told to by the previous builder balance that elevator 
before u fly it! I am going to balance it for piece of mind! I am going to 
use a piece of chromolly on each side of the elevator and attach it to the 
elevator. How have other's done it that are flying I am looking to have mine 
looking like marty roberts plane how did he do it. I don't have his email 
address and would love to talk to him about how he did his!
cheers

KR>how long!!!

[Ross Evans]

HI netters. I am 24 now I bought my plane at quite an advanced stage 
probably about 70-80% I have had it since july last year and have put in 
about 600 hours. Lucky I am single and young I will work on it or do 
something towards working on it everyday I have just spent about 220 hours 
on the canopy alone to get it where I like. I am hoping to fly at easter but 
will probably have to wait while I save for instruments I expect mid year so 
12 months was the plan at the start and I am trying to go quicker but there 
is always something else but I am really enjoying the building and can't 
wait to fly it. I have been building in a single car garage and I have to 
push the plane outside to work and set up a collapsable bench
Next time I will have a big shed and will do somethings differently in my 
approach. U can build anywhere I have parts of aeroplane in my bedroom, 
resin in the fridge wings at my parents house. I have also had to move as 
the apartment I was in was sold I reckon with all the moving of the plane in 
and out and not having room as cost me probably 70 hours. In some areas of 
building I should have used peel ply and had a jig for spinning the plane to 
make life easy but u live and learn!!
check out www.saaa.com.au go to chapters go to queensland and click on the 
map check out chapter 15 there is some photo's of the plane. The last one is 
a month ago and the plane is much smoother now

KR>RG2200 EFI

[Ross Evans]

HI Guys

In regards to an extra 25hp I have flown a kr2S with  65hp engine direct 
drive with 2 people and fuel it climbed out at 60kts with the best rate of 
climb about 400ft/per minute I found that the take off run was a bit to long 
and on a short strip (grass) I wanted more power as I would not like to get 
in trouble on a hot day here in queensland it will get to 42 degrees celsius 
and performance changes quite considerably the strips I have used in the 
past are in some cases only 800 metres long so it does not give u much room 
for error or misjudgement most have rather large gum trees at the end too!!! 
I look at a variety of engines the 0200 is a great engine but a very 
expensive one to work on
I priced to zero time an engine I was given fixed price's of over $25 000 
aus
I wanted 100hp plus for the strips I will use and some more performance I 
have seen an rg2200 efi run it was on the back of a trayback ute and the 
tray was bending it had from memory a 66X60 pitch it was 3 blade too it was 
only run up to 2900rpm as it was being run in but was not shown any sign of 
even loading up at this stage it has an enomous amout of torque and has fuel 
injection which also helps but I will get better fuel consumption and 
overall perfomance than the 0200 and will only cost me about 3000 dollars 
aus to zero time if I am out in the austrailian outback and for instance and 
I need some engine part the local auto shop will probably have the part the 
0200 I will have to wait!
At the end of the day I would love to have a lancair 4 but I am too a poor 
pilot who wants to fly so I have to look at what will be the best on my 
wallet but also the safety side ways heavily!!!

Here in australia the jabiru 80 hp is a very popular engine but it is a 
direct drive with a carbie it is light and reliable but for not a lot more I 
have got 110hp+ fuel injection and the reduction drive look at the rotax 
engines they have a reduction drive and go very well. I was also impressed 
with the workmanship on the engine!
I understand that u can get a engine for cheaper and that is good but I have 
spent a lot of time and money just to build the plane I would hate to run 
off the end of the strip or clip a gum tree on take off on a hot day so it 
does become a balance of what risk u are prepared to take!

KR>0200 ENGINE MOUNTS

[Ross Evans]

Hi Larry my kr2S has a 0200 mount it mounts at 290mm foorward of the 
firewall I am now using a type 4 vw from the vw engine centre it has a 
reduction drive and fuel injection all up weight is 97 kg with computer and 
all electrical gear starter and alternator. The balance of the engine is not 
at half the length of the engine it is at about 2/3rd's towards the front so 
that should help with c of g if the 0200 is nearly 240 pounds. I hope to 
have it installed with in 6 weeks and then do a weght and balance to see if 
it will work out before building a new mount! I have been asked about the 
distance on the kr2 as there is a guy wanting to put the same engine on a 
standard kr2

KR>canopy hinges

[Ross Evans]

HI guys I built my hinges and canopy in the last month the main problem is 
getting the canopy frame to lift away from the front deck to over come this 
we built a sweeping hinge so as the canopy opens it lifts away it is not to 
hard to do u just have to ensure the hinge lifts more than the length when 
the canopy it is in the closed position I have photo's of them but depending 
on how your front deck is constructed will depend on the sweep of the hinge 
u will need I have an alliminium headertank and a removeable front deck the 
canopy is mounted to the deck which has a beam across
