RE: Nitro models pusher Bobcat?
I really dont know how fast it is going never have had a radar gun but my buddy who has had his plane clocked guesses around 90 to 100mph all i can tell ya is it really moves out plenty fast enough i do have big landing gear on back and a homemade canopy so its not very slick plenty of power with the 46fx if i build another i would have to do the tower75 that everyone is putting in nothing like going faster !!

A shorter noseleg will ensure that once you touch-down, even if your landing speed isn't *perfect*, it will stick - because once the nose drops there will be no lift (or maybe even a little negative force). |
RE: Nitro models pusher Bobcat?
ORIGINAL: Stick Jammer While this may be true, the fact is if you touch down in a nose high attitude the plane should stay on the ground whatever the length of the noesleg. Even with a short nose leg, if you bounce the nose wheel down before the mains, it's gonna ballon. If you have the noseleg so short that there is down force on the wing when all three wheels are on the ground it is very likely that the plane will need exessive elevator for takeoff. Too much negative AOA and it won't lift off at all. Zero or negative AOA can also cause the dreaded leap into the air at too steep of an angle. I've seen prop driven delta wing aircraft that could not get off the ground at all no matter how fast or long the takeoff roll was simply due to zero or negative angle of attack. Just my 2 cents. :) kc |
RE: Nitro models pusher Bobcat?
Just set the aircraft level and It will be fine ,no need to compensate for a bad set up by having the Nose leg too high .
Just reverse the mains and all will be good, even bend the legs further forward a bit after you do that Guess stickjammer has not flown his yet , he will find out when he tries to fly it . after seeing mine fly there are 4 more being built In our club. Might even turn up at Tok In the weekend G |

Employees do not need to be paid for: order processing, label printing and packaging for shipping, Right? With a blind eye all you can see $4.35 for postage. just my .02 worth [sm=bananahead.gif] AT least you can get parts! Wheelpants For My Quickie from Richmodels just dont exist. |
RE: Nitro models pusher Bobcat?
woohoo.....only had to pay $8.02 shipping for my new canopy:D

RE: Nitro models pusher Bobcat?
Lighten up no big deal allready bought it had 2 have it just thought it was a little 2 much on shipping i have had whole planes shipped for less!!!
Just my $10.30 worth Thx Jason[sm=punching.gif] |
RE: Nitro models pusher Bobcat?
Well thats just $5.15 per canopy. :D
Airborne Models wanted $6.95 to ship a $15.00 canopy. |
RE: Nitro models pusher Bobcat?
I finally finished my Tower 75 powered Nitro Planes Bobcat yesterday. I ran the first engine brake in tank of fuel using a tractor prop to keep the engine cool. The engine is quite tight yet but ran very well. I will run at least a couple of more tanks of fuel through it before trying the maiden flight. I ended up reinforcing the boom mounts and replacing the nylon bolts with steel bolts for mounting the booms. I also installed blind nuts and 1/4-20 bolts for mounting the wings. My wife just had surgery this week so it will probably be next week before I get the chance to take that maiden flight. The plane looks great and I think I will have a great deal of fun with it.
Best wishes and good safe flying. Heli-NuBee (Roger) |

the only way that holds true is if the main landing gear is considerably far behind the CG. if the landing gear is configured correctly any negative AOA attitude when on the gear will be corrected by wind force as speed is increased. |

RE: Nitro models pusher Bobcat?
I did reverse my gear, and yes they promptly broke the blocks. I flew it several times and it made a big difference on the rotation and the landing. I had one side break while taxiing. I went to turn and it hopped a little and snap the block. I didn't let that ruin the day though, I just turned that side back around and continued to fly. I repaired it that night with hardwood gear block. Actually, I moved the blocks even furthur forward. Take off rolls are very smooth.

RE: Nitro models pusher Bobcat?
I am flying in the stock position and do not have any issues. Many jets have the gear well behind the CG. I remember reading why years ago be don't recall the details.

There are no issues with the gear in the stock position. After flying about hundred flights in the stock gear, I installed retracts in the same positions. On one flight the nose gear got stuck so I landed on two wheels and held it till I gently let the nose slide down to the runway. If you have issues flying with the stock locations you probably have other issues going on. |
RE: Nitro models pusher Bobcat?
I should clarify that by saying stock locations not gear. I threw out the chrome stock struts after about the 2nd or 3rd flight. I made up several copies of the struts using better metal. I think I posted this a while back with a picture. Post #353 page 15..

RE: Nitro models pusher Bobcat?
Being as how I've only had mine up for 8 flight before I lost it in stall after a power failure........I'll tell you about it sometime, but even though I am a fly of tail draggers, I didn't have much of a problem with the gear in the stock position. One of them popped the block but a little 30 min epoxy and we were back in business. It didn't hop off the runway on takeoff, and on landing I had a little bounce, but it was controllable. I only wished the track was a little wider, so when I taxied in a strong crosswind it didn't have the tendancy to tip and scuff a wing tip.
