I am getting ready to test fly an BVM AFS T-33 this weekend and have a question on the flaps. What is the best landing setting and is there any elev trim to be added. Also is it a good idea to use the speed boards with flaps for landings.

Thanks,
V..

DOWN!!!! Haha.

Seriously, if it flies like a panther, use all the drag-producing crap you ca. Good luck

Vin, How much does it weigh? You want to use about 20 degrees for TO and 45 for landing. The speed brake doesnt really do that much. Make sure that it is set up with CROW. Since it is the AFS version it doesnt have the nasty tip stall/bounce problems that the earlier ones have (It is due to the undercambered cusp center section that they did away with in the afs). If it is heavy it will snap in a tight turn or if you get too slow at the top of a loop. Mind that. Is this Bob Freys? Scotty

Scotty,
Yes it is the one Bob Frey has had for sale. It was built by Mark Taylor and is beautifully done with all the BVM options. It weighs 18.5lbs and i am installing a P-60SE turned up to 170k. I was not planning on using crow as i don`t have the extra ch using the AR9000 9ch rx. I believe the crow setup was for the original or older type wing ??
V..

You are right. The crow was pre- AFS. The AFS versions had the under- cam removed. I had one of the AFS T-33s but sold it prior to getting it finished. Good luck on your maiden. Take some video if you can.

Hi Vin- At 18.5 you should be golden. Mine was a non AFS and was 23# dry. I had a old RAM 750-ran like an energizer bunny but only put out 16+ pounds and was thirsty as hell. I think I figured the loading at 70 oz on that small wing once!!!!!. You should be allright without the crow if you cant get it but if you could it would help. The wing is still prone to tip stall -pretty small tips and hardly any (none I think) washout. I saw that plane, very well done and a beauty. Good luck. Scotty

Scotty,
Thanks, i am looking forward to flying this jet. I have always wanted one but didn`t want to build it !!! ha the F-80 is a fav of mine too.

Just who are you trying to kid ! If it has wings its your favorite... may you always have fun & many gongless landings

You are so right Joe !!! I was even caught looking at Curtiss Jenny at the 1/8th !! ha

'Sounds like it is time for a 12X!

Fly it like you stole it........Because you did![:-][:-]

Vincent,
Been flying one for the last two years on a Wren 54 mk III. I agree, use all the flaps you can get to help slow it down on approach. Just plan a low approach starting low in downwind. I found 2% up elevator mix with flaps, another 2% with the speed boards helps me setup a slow glide speed for approach, but be careful in the turns with this much mix, really easy to pull too much elevator and stall her. The reason for the seperate elevator mix with the speed boards is a little faster glide can be had, such as on gusty days, by just leaving the speed boards up. Note all these settings kinda of get dialed in along with the CG, nose heavy more elevator mix, less as you move the CG back. The T-33 is a CG sensitive airplane when it comes to gliding in for landing and its effect on the final flare characteristic.
Hope you enjoy the T-33 as much as I do, sweet flying airplane once you dial it in to your flying style.
And flaps on takeoff, nice for scale, but to me it makes a smoother, slower rotation on takeoff with no flaps, preferance issue.

Jim,
Thanks for the details, i am assuming the jet is flying with very little aoa on long final approach and flair just before touchdown. I have been spoiled flying swept wing jets for a long time and have not had much time on a straight wing jet.
V..

Right Vin, very low to none AOA on final, let it drop then flair at about 2 feet or so. It was my first turbine and I was too stupid to know what a beast it could be at times to land. Scotty

Scotty,
Well said. I cut about a 1/2" off the nose gear on my T-33 many years ago when it was still a ducted fan model to open up the window for touchdown with a little extra speed. Additionally, I have a really soft spring in the nose gear, just enough to hold it extended with full fuel, no more strength then that. This reduces the instensity of the hop when I touchdown a little too fast, it happens.
