Microjet II
Has anyone built one of these or even seen the plans? I saw the plans advertised in Model Airplane News....i recall seeing an article at one time but not sure which issue. [link=http://www.rcstore.com/rs/general/detail.asp?catnum=fsp04951&catego=PL]Here the listing[/link].

RE: Microjet II
I'm south of Asheville by 30 miles. 3+ hours from you.
The only 1/2A that I have now is a Herr P-51 with a
Norvell .074. I'm going to order a couple of the Kamdax
DF Migs, for me & my flying partner.

RE: Microjet II
Well, it took a week to build and a Saturday to cover and finish...here it is. [8D] Guess it doesn't belong with the 1/2a stuff now as i've gone with a new Enya .09 I had instead of the .049 it was designed for. I beefed it up a bit and made a couple of changes but for the most part followed the plans. Final weight ready to fly is 1.5 lbs. The battery is in the back in front of the stab for balance. I went with a reversed blue angles theme to be visible and different.

RE: Microjet II
That looks too stinkin' saweeet!
That's all I need is another project!
Let us know how it fly's!
I have a spare .25. What do you
think about enlarging it a bit?

RE: Microjet II
Thanks guys for the comps! Yes, I think it would enlarge nicely...in fact, the wing and ribs would be easier to build if they were a little larger. The arrow shaft spar concept worked out well, and with a little larger plan you could proably add a second shorter arrow shaft spar in front of this one a couple inches. Also, all the information is on one plan sheet so that will save a little $$ in enlarging. The canopy is a 5" generic military offering from Sig that i painted on the inside. Sig make the same canopies in 2" increments starting at 5" long. The spinner is 1.5" dia so you'd need to enlarge that a tad and fair in accordingly. The only other thing that wasn't scratchbuilt are the tailpipes...those are some little 1/2" PVC couplings available at home depot, painted silver.

RE: Microjet II
Sean,
Can you tell me about the construction?
It looks like the fuse is slabs & the corners are
sanded radii. Right?
As for the wings.. Symmetrical ribs with balsa leading
& trailing edges?
I'm really thinking about building it in a .25'ish size.
Let us know how
it fly's!

RE: Microjet II
That Enya looks HUGE on there! I've had those plans for some years now, but never built one. I heard the original was super quick with the .049 TD, this one will affect the Earth's rotation, I'll bet.

RE: Microjet II
The .09 should be fun! especially with the luxury of having a throttle! As far as construction goes, it's quite straightforward...the fuse is a basic box with some thin ply doublers on the inside back to the trailing edge area. There is triangle stock along all 4 edges to allow for the fuse to be rounded off a little bit cosmetically. The tail surfaces are just solid sheet on mine (the plan shows them built up i believe, but still flat top and bottom). I knew I was going to have more weight up front with this engine so I went with solid sheet.
The wing is a little more interesting. In the article it shows building them in 2 panels, covering them, then sliding them on the spar and gluing them along the side of the fuse. I built them on the spar before coveing so I was able to get good secure glue joints at each rib where it met the spar. The ribs are a little tricky. Mine are 1/16th balsa with 1/64 ply laminate each side. Then cut out and 1/64 ply cap strips run top and bottom the full length of the rib. Then the spar hole was drilled (a composite extra stiff arrow shaft was used) in each rib. Adding the cap strips first are key as the hole for the spar is basically the full depth of the rib. Then the spar is slid through the fuse, once aligned and straight the ribs were add, balsa leading and trailing edges, then 1/32 balsa sheeting was added at the leading edge back an inch or so, and the same done at the trailing edge. lastly, 1/32 balsa cap stips were added over the initial ply cap strips in between the balsa sheeting to make everything level. Yes, long winded explanation, but it's very solid. The ailerons have 1/64 ply laminated onto each side as well.
The canopy is a generic 5" military offering from SIG, and the tail pipes are 1/2" pvc couplers from Home Depot. [8D]
Here's a couple construction pics early on....

RE: Microjet II
I designed several 1/2 airplanes which to-date are flying great. but this micro jet simply doesn't have enough wing area to suit me. I like 200 to 265 square inches and wing loadings less than 12 oz /sq ft.
I may be a great plane if you up the wing area and found somewhere to lighten it.
