Ok, so I went backed and looked at it and it is panted...on the inside. Hay joe is the one you saw panited on the inside?

RE: VectorFlight 300s, anygood?
 

The cowl on my Extra is painted on the INSIDE of the plastic. I noticed this while fitting my cowling over my engine. The (white) bellypan on my plane is a completley different materieal, which is white. I haven't taken a close look at the BP on the Edge, is it painted inside as well?

RE: VectorFlight 300s, anygood?
 

No problems with paint so far, using 10-15% nitro. VF did tell me they were considering changing belly pan material a while back, dont know if there was a paint issue. I know some plastics act like a non stick surface and dont like being painted. I would email them, no doubt they would replace a bad part without question.

RE: VectorFlight 300s, anygood?
 

Miloh, the paint was on the outside surface of the Edge belly pan. His painted cowl did not show any signs of a problem. I think the belly pan was seeing most of the fuel from his pitts muffler. Wasn't trying to alarm everyone, just a head's up. Miloh, great narrative and photos on your construction, man you work fast, how long do you take to put one together with a healthy neck? Fly it anymore since the maiden? Think you said that it came in @ 7# 15 oz. with a 28 oz. TS. 91engine. Great news if it's still @ that weight. Should fly like a bee and land like a butterfly. Am still considering using a ST. 75 on the Extra. Think it was you that was going to see if your ST.75 would fit under the cowl without cutting it. If you get a chance to confirm without taking everything apart I would appreciate knowing. Think it will be strong enough to haul it thru pattern type stuff? Not looking for unlimited vertical. Thanks, Joe

Hi Everybody,

Out of town on business and just now got caught up on everything. I see Dan weighed in on the subject and I agree with everything he said except the tracking at full power. I do not recall the nosing over at full throttle that he mentions. There is no...none....zero.....zip....nada...down thrust in this engine unless it came from the factory in the firewall construction. I really think (hope) that the elevator to throttle mix has corrected everything, but will take a serious look at the ailerons to see if there is something there. Calflyer, thanks for the info. If I may, you are saying to set the ailerons as a very slight spoiler in the neutral position as in up?

My bellypan came from the factory with webs in the paint because it was put in the plastic bag still wet, but an email later and a new one was on the way. Same situation as David Cutler, they were going as fast as they could. Miloh, on the edge, the cowl is painted red, but since it is polycarbonate, the paint is applied on the inside. I was thinking about hitting my bellypan with some clear spray from Topflite, but have not done it yet and it seems to be holding up well so far.

RE: VectorFlight 300s, anygood?
 

Thats correct, I think what that does is reduce the lift from the wing by adjusting up the ailerons together, just a hair at a time. Just unscrew both aileron clevises one turn or even half turn at a time. But this is only if the airplane tries to climb too much with neutral elevator. On the other hand for a plane which baloons when throttle is chopped, it would seem that the engine has too much down thrust relative to the wings and it is pulling the nose down under power but as soon as the power is cut, the nose is released and it goes up. If the engine does not have down thrust, it could still use some upthrust. Apparently some airplanes need it. But all in all, high performance airplanes require careful setup.

Well just thought you guys would like to know I called into work sick today and took the VF Sukhoi out for it's first flight today. The weather was perfect, 70 degrees and no wind and the Sukhoi handles perfect with no surprises. Just have to get used to it landing a little hotter than I'm used to because I've been flying mostly 3-D type of planes. All in all a good plane especially for the price.;)

RE: VectorFlight 300s, anygood?
 

Sarge, thanks for the update! I have my eyes on that Sukhoi for a while. What engine are you using? any pictures?
Thanks[8D]

RE: VectorFlight 300s, anygood?
 

Sorry no pictures. I'm using an O.S. 90 four stroke with a 14x6 prop. I used 2 degrees right thrust and 1 degree down. What is everybody using to fuel their planes? I'm using a
Dubro Kwik-Fill Fuel Valve and I'm not that crazy about it. I wanted to use a fuel dot system but not sure how to use it so you get fuel only to the tank.

RE: VectorFlight 300s, anygood?
 

Good to hear you had an uneventful maiden. I never got to fly Sunday, our club had an event and the skys were just to crowded, Several guys pushed on me to put it up but I restrained my self. One of the two of the guys pushing went back up with his bird and wham!!!!!!!! mid air collision. right over the runway at about 10 feet. There was this giant scale Stinger with a G62 on a tuned pipe. practicing full low speed passes and another guy hovering a spad over the runway and neither of those guys were involved in the crash........... So I just stood around and watched the action.
Next Saturday will be my first oportunity. Until then

Miloh.

RE: VectorFlight 300s, anygood?
 

Miloh,

I used two fuel dots, one on top and one on the starboard (Right) side.

The one on the right side is the blow by/pressure line. I setup the pressure line by having the fuel tubing connected to the pressure line in the tank, which then goes through the fire wall, then into a three way tee, off the side or 90' off the tee, I have a small piece of tubing going to the Pitts muffler pressure nipple, then the other end of the tee another small piece of fuel tubing going out the side through the fuel dot plugged with the dot plug.

For the filler I have a third line going into the tank, which comes back out the fire wall and up to the fuel dot and filler on the top of the cowl...

see picture...

RE: VectorFlight 300s, anygood?
 

With a Pitts exaust on a side mounted engine, any overflow will simply exit the muffler and dump on the ground. The second fuel fuel dot is not essential. If I watch the pressure line (through the hole in the cowl that I made for the engine) I can usually turn the fuel pump off before any fuel hits the muffler.

Dave,

Do you know anything about setting a radio up for Exponential instead of using dual rates ???

Is one better then the other ???

Sam

RE: VectorFlight 300s, anygood?
 

What kind of radio do you have? Expo vs dual rates is really a matter of personal preference. Some radios you can do both. I have a Futaba 9C, and for my Extra, I have low rates set up with very little expo, and high rates set up with more expo. That way I can fly around smoothly at high rates and still have full surface deflection available for knife-edge, flat spins etc.

Some folks don't like expo, they say it makes the plane feel "mushy".

RE: VectorFlight 300s, anygood?
 

Sam
I set up expo on low rates and none on high rates, it makes alot easier for me to land since it isn't as touchy.

RE: VectorFlight 300s, anygood?
 

I have a Futaba 6EXA 6-Channel FM Radio System...

Sam

RE: VectorFlight 300s, anygood?
 

That radio supports dual rates and different expo curves for each rate, have a look through your manual, you should be able to figger it out!

RE: VectorFlight 300s, anygood?
 

Tracon:

I have that radio and it's my first computer radio. And I put it in an untested airframe. What I did was read the manual all the way through 4 or 5 times. Then I sat the plane in the floor and sat with the radio in one hand and the manual in the other and just played with it. It all came to be fairly simple to use and understand this way.
Good luck, I have found it to be a really nice radio.

Miloh.

RE: VectorFlight 300s, anygood?
 

Don't forget that the expo on a Futaba is a negative figure to get the 'soft' movement at the low deflections.

I use a lot of expo when I have my Hitec set up on high rates. That way I have the security of knowing its not very sensitive at low deflections, but high sensitivity at high deflections.

RE: VectorFlight 300s, anygood?
 

Thanks for all the input guys...I did like Mr Moen said "Sit down and read the ruddy thing"...

After a few hours off fiddling...

I think I got it figured out...

Sam

RE: VectorFlight 300s, anygood?
 

Is a .90 4-stroke (say the Saito) overkill for the 58" version of the Extra? I have a hard time telling from the messages in this thread because people don't identify the size of their Extra, although I assume most are 66".. Just curious if anyone is flying the 58" version with a 4-stroke and how it performs... especially hover capability.

Thanks.

RE: VectorFlight 300s, anygood?
 

Hi there!

I'm planning to put my Saito 100 in my 58 inch, and I reckon that'll be perfect! The thing about a Saito, is it's so light, and you need not use the extra power.

As somebody once said to me, there's no such thing as overpowered, just overweight!

-David C.

RE: VectorFlight 300s, anygood?
 

gnyberg,

I've been using the Saito 100 in my VF Extra 300S 66" for two months now with over 30 flights.

I wouldn't change a thing with anything. I only use 1/2 - 3/4 throttle. And that is only for vertical climbs (unlimited).

RE: VectorFlight 300s, anygood?
 

Well, I flew my Edge again today. The YS110 is getting run in now, and is giving awesome power.

The two flights were the best so far, with great, smooth landings, now that I have realized the ballooning is (I think) caused by the ailerons acting as flaps (I had a bit of flap mixed in my Eclipse which I have now removed).

However (!) on a particularly fast downline, I saw something fluttering away from the plane in the distance, so I landed. I thought it might have been some white covering coming off, or something, but I couldn't see anything wrong so I flew again.

The next time I went back to the pits, I looked under the model, and noticed the belly pan was missing!!

There was no chance I could have found it, so I had to stop flying.

I think I'll use some of the ply I've got kicking around, to replace it.

Other than that, a great day of flying!

-David C.

RE: VectorFlight 300s, anygood?
 

I have the 58" Extra with a Saito 91 and it was a perfect combo. Great performance from the engine!! You will like it
