Best thing is, the price i got it for is a mere fraction of the price it would have cost me to build one
and i also know some very very good pilots (ex airforce fast jet instructors) who will be more than happy to come fly with me when i first get it and make sure i get used to it safley

Quick update (pun intended
i have now bought myself a Tri-Q
its been flying before over in the states, but is now in a stripped down and paint-less state for our LAA inspections
so the winter is going to consist of repainting, and fitting engine and avionics
however the good thing is i will now have an aircraft to play with and fly in while im building the other
-
I also have them, very good docs
-
that happened just next to my airfield, in fact i saw the crash site when i went out flying
silverstone is just on the edge of the turweston circuit
-
how did the forward hinge help ?
-
Id say it makes absolutly no difference
-
Oh, i dont have any particular need to change it to roncz, all i was intending to do was to plug the roncz and the LS1 canard airfoils into the CFD program and see if and what differences there might be
but yes your correct the UK can be quite restricting on mods
i guess i will need to have a little think about what im going to do
maybe my original ideas where there better ones
-
well id say not to think about planning to sell any quantity
im more thinking of just getting the q200 kit to get the AC built and flying as standard and possibly not bothering doing any extra effort with carbon ect
the berkut based thing can run along side (albeit more in the background) as the more deepthought and engineering project while still having something i can build and fly in the Q200
my main fancy for the Q, is the fact its relativly cheap, quick aircraft and fast build as a kit, is the Q really that bad as an aircraft to avoid it ?
im just curious if its more about biases and allegences to the long ez design or actually something seriously bad about the Q ?
-
Thanks for the comments
I may have found an unstarted Q200 kit that looks like a good deal im just looking at the shipping costs
do you think this is a good purchase?

Understood.
I looked at the design as a possibility a while back and came up with what I considered to be positives and negatives.
On the plus side it's fast and cheap to operate. I flew down to the fly-in last October and they had some very nice examples that had flown in from very distant locations.
On the negative side, they land very fast and with the gear out on the canard tips like that, they can be a real challenge to your reflex speed. Imagine trying to land in the rain in a crosswind and hit a puddle with the upwind wheel. Need I say more.
Might one assume there is a rational reason behind that choice?
well yes i understand why the ez type is so popular, but i suspect part of that is the huge amount of builder support they have in the form of the cozy and others
yeah i realize they do tend to land very hot, thats a slight concern but hopefully something ill be able to get used too and live with
the trade off is that it is a very quick and economical little ac so i believe it would suit me well
-
Id prefer one as an unstarted kit if possible
logisticly it wouldnt be easy to transport a built aircraft from the US to the UK either

You may want to look around as a Quickie airframe can be purchase for about $1,000 (without the wings). May save you some time and $$$.
Saw one a couple of months back goins for $1,200, was only missing the canard, engine and prop...
yup i know if anyone see's one for sale let me know
however ill still carry on with this
hopefully i can bring the design back to life
plans are already available via quickheads.com
so hopefully if a few molded and machined parts can be made available then there should be enough there to build an aircraft

Well iv been thinking a lot about what is most suitable for me as an aircraft
and after discussions with the LAA and several people, iv come to the conclusion that building a Berkut style aircraft is not really going to achieve a lot for me, we are limited in engine power in home builds here, also i have opted for a simpler and faster to build design
also one that suits and fits the shape and size of my available Autoclave and manufacturing facility's a bit more comfortably
also of note is that the long ez/berkut style aircraft has been done to death by lots of people and there is nothing new to be gained for the community, the quickie has not had any parts made for it for a long time and its a shame as its a really nice aircraft
so now i am opting to make my aircraft in the style of the old Quickie Q200
I will be looking to use the Wilsch Diesel engine still, and using prepreg carbon for the wings and fuselage
i will be using the original design of having the wheels on the end of the canard and not the Tri-Q design
also of note is that the Q200 used an LS1 canard, this was the design the Roncz was based from (the LS1 was made before the roncz canard existed)
so i will investigate the possibility of using the Roncz airfoil for the canard
i my next decision will be to work out the method to build the canard from, whether to use the tubular spar as used in the later LS1 canard, or possibly a rohacell wrapped spar section that is cured in place with the rest of the canard in a closed mold
anyway for those that dont know what im talking about here is a picture of the aircraft, the original quickie was a rutan design
Started Cad work for the wing
-
did my first solo flight this morning
terrifying but fun at the same time
think i need a lay down lol
-
Don't you think you should be talking to an engineer with regards to how these will affect flight characteristics, structeral requirements, etc?
The example that I spoke of is a prop driven aircraft. That builder did secure design input from an engineer prior to making his mods.
if i was do do this myself then of course i would sit down with a calculator and get input from others
however it was merely a general question of curiosity than and intention to bolt anything onto my own aircraft build
-
how does the rear fins effect balance of the aircraft?
do you think this sort of concept could also work on a prop driven ac ?
-
Y?ou BELIEVE what you posted? Gregs jet is NOT the jet that is being created in that workshop.
Everybody with warm blood knows about Gregs jet. This ISN'T it. Building 4 airframes from an untested airframe seems hardly prudent. YMWV.
where do you get that they are building 4 of them like the picture i posted?

4 jets, one glassair, one SQ2000, 2 vari, and various things on long eze's.
-
wow really interesting
what is the reason for the relocation of the winglets?
fancy letting us in on any details ?
-
the first ply is 30degrees from center line
the second ply is in opposite bias
the 3rd ply is span wise
this is for the moldless berkut wing
this is in uni carbon
-
Im not using glass
im using prepreg carbon, so i will be substituting materials
however the info on the hexcel material has helped me a great deal, thanks
-
thanks that clears that up then
-
To use what is called out in the plans.
Hexcel 7715 & 7725
and 7715 is plain
and 7725 is 2x2 twill
from reading the hexcel site
-
Are most of you using plain weave or 2x2 twill?
2x2 has less of a crimp between the weaves and would appear to be the superior choice
whats the general opinion on this?
-
i dont know anything about it other than seeing the pics on the ezjet page

Just a quick one, im still working on it, just been a bit busy with moving and buying a tri-q recently
been playing around with some fuselage mockups this is one that follows quite a tubular circular shape
just something iv been doing while away from my home computer with all the proper scaled and sized drawings being at home, so the fuse is just freehand at the moment
