Where they $180, or the higher price?
Tam was unhappy to see the $180 price on here, he let me know. The price is $280, which he says is less than his cost was.

That is a good price for sure. I just picked up an unbuilt kit NIB for $600+ shipping. I'm picky how i build stuff, so i prefer starting from scratch and building the way I like. I have Tams gear so i will be making new bulkheads and ducting. It is a big bird! I measure the scale at 1/7.75 which is the same as the Tam's/JL/Skymaster Superhornet. Landing gear from any of those jets will work nicely for the Byron.

I got my shipping notice on Tam's gear today. I doubt I will get to this plane soon, so it will be interesting to see how you do the gear mounts.

I'm considering whether to forego ducting in favor of wheel wells to keep the retracts out of the fan flow, combined with an intake lip

John, while you have some time to deal with this-- go back and check out post# 241-- http://www.rcgroups.com/forums/showp...&postcount=241

Here I put what RC Crafter's says the correct install angles for the mains. Roll , pitch and yaw~!

That is a great reference drawing for the gear. It gets all the angles in the ballpark on any non-rotating scaleish F-18 landing gear.

That is a great drawing. Also got the gear from Tam today. Nice stuff. Compared to my OV-10 struts from another mfr, they are surgical.

I only have the smaller Y/A F-18 single to build---yet?... But I don't see where kit size--matters it's all about getting all the install angles , correct..

Kind of like the front end of you car/truck- toe in /toe out, -- caster/camber?

I just got a chance to unpack and inventory my F-18. it was delivered originally in 1993 to Guam. It still has everything that was sold with it. If anyone has any interest in old Byron stuff like the retract system or the sure flow fuel system let me know. Had a big head OS 91 bolted to the fan as well. Never seen fuel. I'll be letting all that stuff go. Well, not the fan, but the motor for sure.

Back to work finally

Just got the new Robart 635 low profile retracts on Fed EX. I got the Tam struts back last week with re machined axles to fit the BVM wheels I have. The machinist cut the grooves for the wheels retaining snap clips a bit too far out on the axles so I made some 3/32 x 3/16 spacers from some wheels collars to obtain a good fit.
Now I can get back to fitting main gear mounts and install all the formers in the fuse

Good news! Getting all the formers glued is always a nice milestone. Very happy to see you back on the build.

I'm still deciding how to power mine. The Dynamax is the most practical. Twin 90 would certainly help get the total thrust up above 20lbs, but would be heavier and require some long intake ducts (2 D- shaped ducts making a 5 inch circle) all the way past the gear and split back out to 2 rear mounted fans. It would be interesting. I have a long way to go before I have to worry about power systems. Your testing will certainly help my decision.

Here we go

had the main gear in , and looking almost right. took measurements.
I cut out one more mockup main former and rear gear mount former.
I really believe this will be the setup. I will install it all tommorrow and check it all out and if it proves out then I can use these to make the final formers and make up templates for some of you guys who are using the Tam struts. The Robart 635 lowprofile retracts are giving me so much more clearance to play with and not alter my inlet.
Glad I waited till I could get them. These mock formers are just some cheesy 3/16 ply from an old crate but will be fine for fitting things up. Not structural at all. I will take some pics with the gear in and post soon.

time out for dumb thumb!!

I got really dumb and stuck my thumb into the saw blade of my dremel table saw cutting out the lang gear parts. Sliced a chunk right of the end of my right thumb. Thumb is flat on the end flush with finger nail, took about 1/16 right off. Not sure what hurts worse the thumb or my head for not being more careful????
Will finish cutting the landing gear mounts tommorrow.
Did get the Dynamax re assembled with the Het 685 sleeved motor from efflux rc. Also got an het heatsink for it and got it modified to fit the setup , will have to get some more arctic silver paste to put the heat sink on
Got a package from Castle with 6.5 bullets , capacitor pack
and 10ga wire for hooking things up.
Anway after a couple days off for the injury will get back at it tommorrow
