Re: New Taylorcraft BO-200

here are the damentions of a o200 and a 0320 b conical mounts 160 hp length 0200 31 11/32 o320 29.05 both with starters height 0200 28 3/4 0320 22.99 width 0200 31 1/2 0320 32.24 0200 with b&c starter and alternator bendix mags and air box and carburetor 210 lbs lycombing 0320 b 277 with heavy starter and alternator light starter and alternator 12.62 less equals 264.38 or the 0320 is 54.38 lbs more then o200 but 60 HP more as per my C85-12 with a starter on a short mount they will fit under a short cowl with starters

Re: New Taylorcraft BO-200

I wouldn't mess with any trim tab. I'd throw that away and put a jackscrew on the stabilizer instead.

I am just the opposite.
Taught to crank up & down for landing & take-offs, then minor adjusts for cruising.
You know what, forget all that, I don't bother to move it for landings or takeoff, why? TCs are not heavy to handle, I just leave it in the middle position with occasional minor adjusts for weight on cruise.
The original is simple, light, effective, why would you want something other than that...IMHO of course

Re: New Taylorcraft BO-200

Biggest problem with a Piper type stab trim system is it requires a redesign of the tail, new load paths and it is HEAVY compared to the tab. Worst the weight is WAY back in the tail requiring 6 or 7 pounds in the nose for every pound in the tail.
The neat thing about the electric servo tab is it is even lighter than the current system. The paperwork is way too much trouble for a certified plane, but for an experimental it is simple, reliable, effective, light and cheap. With a very simple circuit design and two more servos you could even have a basic three axis auto pilot! Not that I would want it on a Taylorcraft.

Re: New Taylorcraft BO-200

List of goals so far, as I see them. Any additions, corrections?

Overall
1. Maintain Taylorcraft look.
2. Minimize re-engineering.
3. Maximize cargo carrying ability (minimize empty weight).
4. Increase Comfort.
5. Improve Safety.
6. Design for 1500lb Gross, but keep it usable with a 1320lb Gross.
7.

Fuselage
1. Make from 4130
2. Widen Cockpit (4")
3. Raise lower instrument panel bar.
4. Remove Bungee mount.
5. Move seat back tube aft.
6. Adjustable Seat.
7. Slightly increase door size.
8. Change Strut / Gear mount.
9. Eliminate fuel tank.
10. Shoulder Harness Mounting.
11. Skylight.
12. Patrol Doors.
13.

Tail
1. Increase Vertical Stab ?
2. Increase Rudder ?
3. Early 3 hinge.
4.

Landing Gear
1. Eliminate Bungees.
2. Change to allow baggage pod.
3. Hydraulic Disk Brakes.
4.

Motor
1. O-200 with small starter & alternator.
2. Short mount.
3. Modern baffeling.
4. Secondary ignition electronic instead of mag.
5.

Wing
1. Full span.
2. With Flaps.
3. Possible wood ribs?
4. Struts redesigned to eliminate possibility for corrosion.
5. Fuel tanks in wings.
6.

Re: New Taylorcraft BO-200

I know very little about building/designing but 1,320 lbs???? With all of the above??? A Taylorcraft L-2B is 1,320 and an L-2M at 1,325 with built up wood ribs. Already has fuel in wings, except for 2 gallon header in fuse. I just see a lot of increases but not a lot of leaning. Who knows, good luck!

Re: New Taylorcraft BO-200

When I mentioned piper trim system I was not aluding to jack screw system. I should have been more clear and stated j3 style with double wrap pulleys. Factory system is fine, just needs help.

with that list just go buy Forrest's spare F22 fuselage and save yourself the headache.

Re: New Taylorcraft BO-200

Good point. Any suggestions for where it could loose weight?

Re: New Taylorcraft BO-200

Don't think of the list as additions to the basic design, they are CHANGES to the basic design. With some careful engineering many could actually reduce the final weight. The key is to think in GRAMS, not pounds. If the new design components (say seats) aren't lighter than what was there before, you have more work to do. There are several areas of the Taylorcraft that violate the "One Horse Shay" rule. What is needed is to design so that everything is just strong enough, and NO STRONGER. The primary goal of every aircraft designer since long before the Wrights.

Re: New Taylorcraft BO-200

Hey eric. Sounds like a great project. Having a 160 Hp experimental BC12D built by someone else I am . Wishing I had a set of D&E aluminum spar wings with flaps . With these wings and a set of 2000lb rated struts form airframes alaska you could bring the gross up to 2000 lbs. Also I mated my 0320 with a three blade composite Catto prop . Its 12lbs lighter than the old Mccauley 2 blade. Soo much quieter and smoother. The initial takeoff thrust is phenominal and it climbs like a homesick angel. Just a couple of ideas from a guy already flying and experimental hot rod Taylorcraft!! Good flying , Murray

Re: New Taylorcraft BO-200

If you wanted to keep it super lite, and since it's exp. anyway, why not a rotax 912? What's that, 50-75 lbs? You'll have to do some extra work because of cg.
