Anyone know the thread pitch for the wing bolts and the horizontal stab bolts?
My manual shows a 4mmx20mm for the horizontal and a 3mmx10mm for the wing. But does not show the pitch.
Anyone know where I can get some of these?

2015 elan
abs type pulse brakes,adjustable via xicoy data terminal ,can't wait to try . Jet cat 90 rx jr 8711 servo on all surfaces except nose steering . Smoke by Sullivan , Kevlar split tanks, for fuel and smoke oil , no Ferrari decals, although Larry would have supplied them ,, he's great but I choose to do some graphics , tons of room by not having the air tanks, but you do have to run Accra battery but small ,
the charger on board is AR. booma Rc sells them , dream works is a dealer ,, it chargers two a123 2300 mah under fuel tank, and also 1-lion 2800 mah for smoke pump and the prolink Gear brakes etc .

I don't know about the latest Elan, but my old one had open holes for the wing retaining bolts and inevitably I dropped one into the wing, annoying rattle for ever more, eventually I glued a couple of tubes into the wing to stop it happening again, just thought I would mention it.

Nice Jet Indy.. looking great.. love the paint!.. good luck with it.. love the jet.
I would recommend that you remove the festo fittings on the suction line into your fuel pump.. many guys have good success with them, but I did not.. My first élan quit because of a festo on the line into the fuel pump. it sucked a bubble..
Instead this is what I use
option 1: run a small piece of 4mm line off the pump about half inch, and then run the 6mm line over it and safety wire at the pump barb
option 2: run a barbed reducer from 6mm to 4mm.
Also I would remove the 6mm coupler on the main feed line. Instead put about 6 inches of 6mm line there and loop it around, with a hair dryer, and safety wire it to the trap.. I know you put that there so you can get the tank out, but if you leave a little longer line, you can lift it out and set it to the side.. spoken from experience brother!. Try to avoid festo fittings for suction.. some designs can't avoid it but in most cases it can be done..
Awesome jet

Cool
I had a bunch of jets too.. came back to the élan and kingcat.. they are still my favorite planes.. I kept my Ultra Flash as a backup.. got rid of everything else recently.. I just love the way it flies and how easy it is to fly.. I find myself flying a lot more with it.

Well i did the maiden today went real nice,, just few clicks of up elev. to be expected since i did not add the shims in the rear of the stab yet.. i actually had a 4.5 mm alum shim but took it out. i figured i rather just fly the way it is,,and see how much shim it would take to make cleaner flyer,, so i think its aprox 2-3 mm so i will sand the ones i have down and hysol them under the stab on the booms. other than that ,, flew like a élan always does,, one click of aileron cause was windy out of the ne site is east west . so . cross wind we had blowing 15 mph easily . the smoke pump worked nice with dense smoke,, i have twin tubes. on it. that was fun. Electric gear worked great but the electric brakes worked to good flat spotted a tire when i was using the pulse abs for braking,, guess i have to dial out some gain or less pulse or more pulse not sure yet . i have a classic flash love it just got it from a friend . i have 16 flights on that puppy its awesome!!

I am considering buying a Boomerang. My local field is grass, and well cared for even irrigation so, one big issue I have is grass scorching. My first jet was an R 54 and would leave "skunk" trails on the grass.
What has been your experience with this issue?
I noticed some builders may down thrust the turbine to avoid horz stab heat. Can this be overcome with shielding and how? I also noticed shimming the horz. Is this to overcome down thrust on the turbine?
And even if I need a new stab every X hours may be manageable.
I have enough parts on the shelf to build, JM90 gas, electric gear and brakes etc, except fuel tank.
Any input would be appreciated.

Boomerang Elan and grass burne
Rge Elan is not particularly hard on grass compared with some other plane. Nothing like the Jetcat, Bobcat or any similar planes. There will probably be some scorching, particularly if you do static run ups on the grass but I would certainly not alter the engine mounting to try and improve this. The result on performance would be substantial. Do other pilots fly turbines at your field? If so, the Elan won't be any worse on the grass. In any case, most scorching is gone in a few days. Good luck.

My Elan never scorched the grass with either the P80 or 120 set on the standard out of the box mountings, the tailplane was not shimmed and it flew straight and level at full power, I would not worry, on take off hold the Elan on the brakes and apply full power when it starts to move release the brakes it will take off in a very short distance without leaving any marks.

NC,
Thank you for your reply. I have a static run tube made of double wall furnace pipe with a 90 degree upturn exit. I built it for the R54 as needed to keep from burning the tail during static run. Glad I made it adjustable height.
It varies from about 2-4 jet guys in this area but I have only seen piped jets so no scorch issues for them. I have not been jet active in several years but kept most of my equipment. I sold my P60 a long time ago and thought about putting a K45 etc back on the R54 but the scorch issue deterred me.
The Boom is to get me back into jet flying. I spent a year rebuilding a large scale Aurora I bought but JM200 and 54Lb plane is a little intimidating to start back on especially $$$ to replace.
Going to order a Boomer. FYI Roger said he is still in business and expecting another container of planes soon. Currently has a few red and white military and sport on hand.
Cheers
Charles

Tank delivered, kit slated to deliver Monday.
I did try scrubbing the thread some but I still have some questons:
what power servo do you use, I saw one using DS821 on ailerons 4/6v 72/88 oz torque. I did not find a recommended servo in the manual.
Anyone who used kit servo attach hwd, any problems? I did see some suggest upgrade LG attach screws
Hwd in general
Thank you
Charles

I talked to Larry for the servo he recommends and he said all they use is the Hitec 5645mg, they never had a problem with them, so that's what I used, finished mine about 3 weeks ago
waiting for weather to break to put maiden on, servo's seem to work fine, high tork at 6.6 v. Ordered from a place in N.J. they where around 34.00 each no tax and free shipping.
Good Luck.

Tag, Thank you for the shout back.
The BOOMER has landed!!! Just like Christmas.
Down side freight company speared the box but "only" crushed the cockpit floor. Horz looks OK but first order of business is to open the servo bays and check rear hinge spar.
First hurtle, the spar tube does not pass into the center section. Should I just work the outer ends ID of the fuselage tube with sand paper on a dowel for close fit and no bell mouth? Fits the wing snug like it should.
AS da mun say "dant worry, be happy"

First new plane for me in a long time. May even add protective wrap to big areas to keep construction scuffing off finish. But its just a sport knock around flyer.

I could not get the wing tube thru the fuse at all, finally cut out all the tubing that was running thru the fuse, and it turns out the open from one side of the fuse to the other is about 1/6" or more off. Sanded out the fuse a little bit and got it thru, but it is never coming out.
