Status: offline 		Okay fellas, I am in the market for a 1/7 F-15. How would you stack the F-15s by FEJ and FB in terms of quality? Also, how do you think the F-15 will fly with a P-160SX? Better than scale? Or is a P-180/200 necessary?

Thx,
DD

Status: online 		Hi DD, NO CONTEST! The FB F15 is head and shoulders above the dreadfully engineered and grossly overweight FEJ one. How do I know? I own them both.

The FB 15 will fly on a 160, won’t sparkle, will fly though, the model can come out at around 42-43 lbs. Both mine have twin 160’s.

Status: offline 		The FB is by far more scale and better looking including the landing gear which FB has very accurately reproduced in 1/7 scale and will fly on a 160sx but better if a P-180 is in there....

Also I can provide all the decals in this scale for the IAF F-15I "RAAM" ...Actually for all the "birds" that are in service with the IAF.

Regards
Peter

Why are you resisting a P-200? Don't be scared, stop listening to Arnaud on engine choices will you???

Raffy!!!! I'm going to stuff a P-200 in the 1/6 F-16. I guess I am going to stuff a P-200 in this F-15 too.

Status: offline 		I dont think a 200 is really required by any stretch of the imagination. Iam going with a Merlin M160 in my one which offers very similar thrust to the turbine installed in Lewis's FB F-15E, that said his model was a pre production prototype and somewhat more heavy again... So the lighter new production version with the same power 160 turbine will be even stronger again.

Status: offline 		Not sure about exact thrust of Lewis's turbine? but remember the production airframe is now much lighter also so performance with a strong 160 (Merlin 38~40 lb) should be at least on par logically

My F-15 has the LPSS Rhino.  Thrust is 40 pounds.  Flys the 15 really well.  Soon will have the new Jet Central Mammoth at 45 pounds.  That should make for some very good verticals with this airframe.  Dry weight of my F-15 is 42 pounds.

Ian is right about that. Just want you to know that we have the bulkheads and pipes set up for twin! The cost of 2 P120s is comparable to a P200.

Status: offline 		A single P-200 will give you more fuel for flight time than two P-120's....

a single engine is more fuel efficient than two that are at the same amount throttle thrust setting...Besides ...the single engine setting is lighter the a two engine installation.

Lavi_rider has good points on single turbine configuration.

However, this is an impressive F-15, especially with true twin configuration, and you get to bring it back when 1 engine goes out. Fuel economy, who cares? Al Gore?

Anyway, both options are good. Try to flip a coin.

Mike

Status: online 		The single setup would be lighter but with an F-15 weight is not really going to be an issue here. 2 P-120SX's are only a pound more than a P-200 and as far as fuel consumption goes a 120 sucks 12 oz. per minute at full throttle and a 200 sucks 24 oz. per minute so its a wash. It basically comes down to a couple of things for me.

It basically comes down to whether you want a single or twin setup, heck, even twin P-80SE's will fly this plane, but the 120's will give great vertical I am sure.

Mike, for the twin setup, whats the fuel capacity for each engine?

Status: online 		In my opinion bifurcated models always sound wrong, plus the F15 needs two 160s to perform as the full size, with two 120s you will not be able to take off and immediately pull vertical, the real one can and does. With the supplied fuel cells you can easily get 12 to 14 minute flights with the 160s…….go for it!

Doug, I hear ya bro. The two hunny will cross over well! See ya at the Willow!!!

It does lack the "scale" power, but it does fly fair. i think a P-200 would be better suited for this heavy model.

Why go a twin if you dont have too. More weight, drama ect. My single P200 powered Mig sounds louder and more realistic than my mates twin P160 powered Su27.

Status: offline 		Levi, this is a old thread. I was interested in the F-15 a couple of years ago, but lost interest because both manufacturers were having problems with their planes.

BTW - I responded to your PM about the MIG-29 pipe, but I got a message saying you can not accept PMs.

If I were to get a F-15, I would use a P-200SX.
