John,

Why not get the new HSR-5995TG Ultra Torque for the same price. degrees
heres the link http://www.servocity.com/html/hsr-59...ra_torque.html Looks good to me.

Prime time
At 6 volts it has the exact power and speed as the 5955.

417 oz of Torque with .12 sec/60 is only at 7 volts. I doubt your running 7 volts. I believe this is the servo they were having some trouble with (locking up) when they tried to re-program it.

Yep, the 5995tg was the servo with the trouble. It's designed to rotate 180 degrees. The 5955TG is the one you want.

John,

Wow, Im glad i said something then. huh, you know thats the one people are going to look at. Espicially with the same price!
Did you look at the servo power gearbox, makes me wonder. I mean all that power with the 5645 and you can get a 2:1 ratio with 336oz. estimated save probly only a few bucks. I dont know, what ever your up for doing I guess. Why not use the Composite arms they give you?

yes you could save a few bucks, add some weight and cut your speed in half (just guessing on the speed) Get a 5955 and be done with it

Yea, The only plane I saw with the Evolution 58 on was the KMP Yak. If you already have the motor it will work, But the Da 50 is the best motor For the EF yak. The weight of the evo might be to much. I think the 45 evo might be better. The 58 might be over kill Im not sure. Thats what I heard. heres the link http://www.horizonhobby.com/Shop/ByC...rodID=EVOE45GX
It isnt

The 58 will be too heavy, the new 45 might be a better choice. For the money of the evo's I would just get the DA, it is the best for this plane. If you want to save money and have a great engine get the Brison 3.2. I have it and it is a great engine, not as powerful as the DA, but it still will hover the plane and pull out good.

Ricmussman, what prop are you running on your Brison 3.2? Saturday I tached mine at 7470 with a 3W 22/8. Engine has about 2 1/2 gal. through it. It is ballistic. After anoter gallon, I will go to a 23/8.

I am swinging a Mej 22X8. I will tach it tonight last time I checked it was 6900, I have ran a few more gallons and I will tweak it for some more power. I tried a Mej 23X8 it was too much for it. I would like to get a Mens 23X8 or the like, the CF was just too much, wood would be better in that size. Either way it still is the best flying 50cc plane ever!!!

Hi Ricmussman,

If you do that, you'll be going in the wrong direction. A Menz S is a much higher load prop than the Mejzlik. Mejzlik's are one of the lowest load props there are. If your engine won't pull a Mejzlik 23X8 in the 7000 RPM range, you have an issue. It should be turning the 22X8 in the 74-7600 range. I don't know what muffler you have, but that's the first place I'd look.

BTW, the MVVS/Evo 45 will also turn those props in the same range...with the MVVS can. It is definitely an excellent alternative to the DA.

Next silly question -- I have 4 slotted bases for the rudder control horns. Am I supposed to use all 4 or just 2? It's not very clear if I need them all or not...

Sounds like you have some extras. Use two for the rudder horn.

I recieved 4 as well...

I used two each side. Sliding one on from the back and the other from the front. I glued the one in place then placed a little epoxy on the bottom of the second one and slid it over and down onto the first. They interleave and "hold" from both sides.... but in reality one would be just fine too...

Just checked Central Hobbies, the largest TT spinner they have is 3 1/2 (P-51). Any other places to order from for 4 inch?

I ordered my 3 1/2" P-51 style direct from TT. Drilled for the DA-50 and cut for Mejzlik 22X10, 23X8 and a Menz 24X8 (I am going to use a tuned pipe so I might be able to use the Menz...)
