Maybe. If you y-harness your ailerons together will that not leave 2 channels available for you to "marry" the flap servos with? You could still have a flaperon setting available to you if you wanted, or just a 1 or 2 position flap setting. Try the same mix you used on the ailerons but switch it to gear/flaps and see what happens.

Hope this helps.

Am I on track with my answer? Oops, didn't see your post. I'll give it a try

I knew it would not be as fast but being I put both of the together I did not expect there to be as much of a diffenence. On that note I took all of his training stuff off and noticed it flies "normal" now.

Phill, what model it your F-4? Very sharp looking jet/plane..lol

Its an older Lanier ARF. It is fast but that is about it. More of a point and shoot prop jet.

cool thanks, do they still make that model?

I think so. I bought mine at Hobbytown about 6 months ago. I know you can find them on ebay for about $125 or so.

Has anyone put an OS .55ax in their raptor. If so, can u tell me where u put the lead weights in order to balance it? Did you balance it with a full or empty tank of fuel? How much extra weight did u put on the nose or the tail?

thanks in advanced

509thBoomer

I had to put put a 3 stick on squares squares in the nose and move the battery forward to get mine to balance.

they do have an arf version for the p 51 and the f-22 without the radio and engine

yes they do, here are some links ( http://www.horizonhobby.com/Products...ProdID=HAN2845) (http://www.horizonhobby.com/Products...ProdID=HAN4375)

I just buddy boxed an beginner who brought his new Raptor out to learn to fly on.

I've got a couple of observations.

It was a warm day. Density altitude was about 1500' and that airplane as sold really wasn't up to the challenge. The prop-engine combination definitely wasn't good enough. First order of business was to set the flaps to zero. They would have killed the sucker dead on the first lift off. As it was, with the engine tuned to as high rpm as it'd give, the airplane barely got airborne in 200'. It was on the edge of a stall the first lap. It took a bit of forward elevator stick to stay level, so don't bet on it being stalled, it wasn't. The thing was simply underpowered. I had run the engine on the ground about a half tank alternating max setting and rich setting to give it some hope at a breakin. The advertising says what? None needed? The owner said he'd run two tanks. That engine, that prop.... lousy advertising.

What amazed me was the CG and the main gear location. Jeez, this deal is getting old. The airplane balanced where the book said it should. The main gear placed the wheels just about directly under that balance point. Gear design of tricycle gear is well understood and documented. This airplane would sit level, but push the tail down and it stayed down. How much purchase is that nose wheel going to have balanced like that? Almost none. Ignorance isn't an acceptable excuse for a manufacturer to blow this design point. They should have QA that fixes dumb things. It's past ignorance. It's stupid.

For the 2nd flight the prop got trashed and a 2blade retrofitted. The sucker still took a fair bit of runway, and didn't get on the step for half a lap. But did move along nicely once up to speed. It will fly slowly without much drama. I liked the way it handles. But a beginner's plane, it ain't. And quite frankly, I think the advertising ought to wind the mfg up in court.

I think the owner is going to take my advice and get his machinist buddy to bend him some new gear that's an inch taller, and has main struts that angle back about 15-20degrees. The CG is good for flying and I think I talked them out of moving it to get the pig to taxii better. Nobody should move the CG to get better taxiing behavior. And they're looking for an even better prop. I think the engine will come up on hp with a couple more runs behind a decent prop.

A--mazing...........

I guess I got lucky. Mine has been a real pleasure to fly. I have an OS 55AX and now a pipe on the nose with an 11X8 prop & 30% nitro. Mine is a rocket to say the least. I have noticed that the rates were to low at first for my tastes but now it is just right. I have gone through a few props with it but that is just the gear design. What I have learned is stick with this plane she will come around and IMO no this is NOT a trainer! I think the most fun is rolling all the way down the runway, pulling vertical and rolling left or right just like my F-22 brothers do it at Nellis. The plane almost looks scale in that mode. I am going to buy another and fab up a set of retracts for it... Stay tuned!

Not to bust your rocks but, you are a moderator and couldn't figure out this plane is not a beginers plane ? Evolution engines as far as my RC career goes, don't have a lot of praise about them, in other words I haven't heard much about them being good engines. I think the PTS system is for someone who hasn't flown a prop jet type plane, so the buddy box system sounds funny to me . I am pretty sure you know MFG recommendations on a plane is usaully an engine that is just enough to get it in the air and nothing else. Is the engine a .40 Evolution ? If yes this engine on a 6.5-7 lb plane is a no no, especially a delta / jet type plane. One to grow on I guess.

da Rock

Actually, your intent is to bust my rocks. Only problem with that is the entire post is trying to get across that advertising it as a beginners airplane is basically fraudulent. Plus the thing has a design flaw with the gear!

But thanks for restating the obvious. And if you'll reread it, you'll see the post shows "I figured it out." I'm hoping that it'll help others do that before buying it as a trainer as is.

509thBoomer

Agreed, if you look at earlier posts my buddy bought his as a 2nd plane the same day as I got mine. The first time he went out on his own he made a small pile of F-22 parts out of it. Granted everyone will crash but he said it got slow and fell on a wing and he could not recover in time.

Its still a fun sport plane though!

So just out of curiosity, I am at about 5500' of pressure altitude, probably higher density altitude (stupid Denver heat). It will be a real test, anyone got any tips on a prop to go with the stock engine to help this bird out? I am new to flying, I can fly in the sim with ease, which is why I upgraded to this plane right away. I have been building for a while, so I have some experience.

I suppose my runway is about 300 or 400 ft (not sure), so I should have enough room to abort if things look iffy. We usually tend to abort halfway down if it isn't gonna go, the city won't let us plow down the weeds around the field.

Thanks!

509thBoomer

Hmm, I am guessing you have a .40 on it? If so I would run about a 10x7 (someone chime in if I am wrong) and a 10x8 if you are running a .46. That seemed to work well on mine when it had a .46 in the nose but we are at 2500 not 5K

Thanks Boomer. I have an assortment of props that I can pick from, I will take those with me, and see what happens when I kick the tires and light the fires (sorry, had to get a top gun reference).

509thBoomer

Just remember to get help if you need it. This is a hobby where you can lose a lot of money for being "macho" and quit the sport. If someone will not help you, then kick them in the nuts and ask someone else!
