I wanted to bring back a classic from the 80's with a 21st century twist, so i decided to throw in a little curve on a really good old airplane from the good ole days and scratch build something that would be quite manageable in size and provide good fun for when the slopes are cooperating with wind. So, here i was trying to decide whether a Coyote or an SR7 would be occupying my working table for a couple of months and I finally came to the conclusion that for the first time in a long time, I was going to be working in a scratch-built coyote. After a few days considering which airfoils, overall size, proportions, wing loadings would be good for the plane, I decided it would be a great idea to produce a smaller version of the venerable Coyote... So, here i was starting to work on a plane that would bring back my old memories from my early days into slope soaring and came up with a 46 inch wingspan that brings the plane to a 64% scale from the original. It's got a v-tail also (this is the 21st century twist)

Anyways, It came up really nice. E205 airfoil, V-tail, 2 sq. feet wing area, 32 oz flying weight which brings the wing loading to a whooping 16 oz./sq ft.... Yeah... I know... it looks pretty heavy for the size of the plane but the E205 loves to fly loaded up... I could have used the SD3021 but my previous experience with the Eppler gave me an inclination towards using it on the Mini Coyote Vee. Love the performance on the little plane. Super stable, loves to fly...Continue Reading

Last December I decided it was time for my 30 year old Bird of Time to come down from the shelf and meet the air once again . Hmmm! what a surprise for me after having her stored for nearly 7 years in my shop.
Somehow, the fuse was plagued with what it seemed termite damage. Before peeling the fuse down I figured it had a weird noise of its own resembling one of those "Rain Sticks" (sold at those touristy novelty stores), in a lesser extent but apparent when I handled it to inspect after coming down from the shelf. My surprise after being in denial for a few moments, ...it felt like crackers, I pressed a little hard and the monokote gave way. The wings however, where in perfect shape and form. No damage whatsoever.

Anyhow, after mourning the loss of a great half plane I decided it was time for the BOT to have a new fuselage. Trying to decide whether to buy a part from Tower Hobbies and get it done with right away or scratch build the fuselage, the latter idea won and I started the project.

It was done in a two week time frame, not working everyday but I gave her a good deal of attention for what the plane had meant for me for so long.

The initial idea was to rebuild the fuse and get it flying as soon as plausible, but after seeing how the fuselage came out I couldn't stand the look of the wings. Good thing I decided to overhaul them too. I found a few cracked ribs and both trailing edges on the outer dihedral panels were very soft and brittle, so,...Continue Reading
