Default Lanier F-4 Phantom

Does anyone here have experience with power and speed figures for this plane? It is really a nice ARF and I want to get maximum speed but also keep the engine weight at a minimum. Recommendations?

Well- I have one with a YS-45SE and Macs pipe and it is pretty quick... I never have any idea on actual speeds...

The airframe is a little bulky for all out speed- I love mine but it is nowhere near my Patriot when speed is on the menu-

Some folks on here fitted B&D Air retracts on the F-4 and it came out well, and cut down the drag a bit-

I tried a 9x9 APC for speed but the fuse is just too fat so I went back to 10x8 APC-

What engines do you have or are considering?

Jett-50
YS-45
Rossi-45/53 (heavy though--)
Webra 50GT (lightest I think--)
K&B Screamin' 48

Would be great-

Lemme know if you have any other questions about the F-4... I have put mine through its' paces and survived a flat-spin with her also !

James,

Thanks for getting back with me on this. I have a few K&B 40's from my Q500 days, but am open to suggestions. I have heard a lot of good things about the YS engines but have no real first hand info on them.

Regards, Bill

Are those K&B racing engines?

A standars 40 would barely fly this bird-

Keep an eye on the "Swapshop" for some good deals-

James,

I think that my old K&B may be too tired. I am going to go for the YS.

Thanks, Bill

The YS-45 is one of the finest engines I have ever had (and I have had a few-)... Just make sure the tank is OK when the YS pressurizes it (some split-)

Also, the YS loves a pipe (Macs 7.5CC) or quiet pipe- It will be strong on the stock muffler but would be wasted on the F-4 without a pipe-

Mine simply runs beautifully... You can put the tank anywhere you want, way back, high, low etc..

Keep me posted

James,

I will surely keep you posted on my progress. What is a fair street price to pay for the YS45?

Thanks, Bill

New they are about $180 and the pipe-header is about another $50--

I would look for one used right here on RCU- and if you can get the engine and a muffler (or pipe better yet-) I would go $120-$140 if it has the pipe!

Keep your options open though- I have seen many Rossi's, Webras, and MVVS-49's go cheap on here-

Good luck!

I have the F4 also but haven't flown it yet. You guys might think i'm nuts, but i put an OS 61FX on the nose with a macs tuned pipe. I used a different mount and had to drill holes for it in the firewall. I also had to move all of my servos and battery to the tail to balance it without adding weight. It came out pretty good.

If it isn't a speed demon it's going to get sold right after the first flight. I expect a fairly short take off and a quick approach.

Any thoughts on the speeds I'll see with this thing? I had a modeltech dragon lady 40 with the 61FX and tuned pipe on it and it would haul azz!! If it isn't as fast as that plane or faster I don't want it!

I actually have no idea...What prop. you gonna run on the 61FX? Maybe you can run a 10x10 or somethign for speed-

The F-4 is kinda fat actually- It lands hot with my YS-45 which is lighter than your 61 so keep up the speed on landing and leave room for a nice roll-out!

I have no idea about the speed- but it WILL be faster than any Dragon-Lady!

Keep us posted-

James,

I ordered the Magnum for now. The war department has put a limit on my engine budget. However, Christmas and possibly a YS is not far away. I have a question about tuned pipes, headers, etc. Are they readily available for the Magnum and what brand is most commonly used?

Thanks, Bill

Which Magnum? Is it the 52 (Blue head)? If so, those are actually pretty strong engines (from what I have seen at the field-) As long as there are no air leaks around the carb.

If you want a Pre-tuned system check either MACS or Tower Hobbies for a tuned pipe/header combo. I am pretty sure the pipe/header for the OS-46FX fits the Magnum series- (May wanna double check tho)

You can get either a quiet pipe or a regular tapered pipe- the regular pipe is VERY LOUD so if you have a DB limit get the quiet pipe-

Other options are Ultrathrust Muffler, similar price to the pipe combo less hassle bolt and go-

Or throw a Tower muffler ($13-) on there for a quick 600-800 RPM's 'til you get used to it and get a YS-

Just thoughts, your mileage may vary,
james

Aloha,

Anybody think it would be possible to scale the tailfeathers a bit better? Maybe rig full flying stabs to compensate for the smaller tail surface?
Just a thought...

I would definitley buy one if it looked a bit more scale, or wasn't too difficult to modify.
