Mine is now with CG at 280mm, is flying better and easier to get the nose up during landing.
With the P300 i can land with 12 minutes and still have 1.5L in the tank. (to big in my opinion)

I will try to do new videos...

SERVO OPTIONS : Manual shows the JR 8911HV which is a great servo, but I already have lots of the JR 8611A servos, which have the same case dimensions, albeit slightly less torque at 6V, which is what I run.
Can anyone think of a good reason not to use what I already have instead of dropping a pile of cash on the 8911HVs ?
Thanks-Mike O

Craig

I will be in Sunfun.. you will be there?

About servos.. i am using 8911 in the wing and the new JR HV (i dont remember the model) in the tail and rudder.
I think you can use 8611 in the wing.. but in the elevator.. i am not sure...but in my opinion for the price of this jet.. you should use 8911 or better servos...

Well for AMA Large model certification you are supposed to use the same torque or better than the manual reccomends...

+1, agree

Yes, this is true. I just posted the same thoughts on the other thread for this bird, expanding on the point that LTMA-1 (self-inspection) process begins at 55 lbs, the weight MUST include being full of fuel.

This is straight from the "Large Model Aircraft" section of AMA Doc 520-A

  1. LTMA-1 are turbine-powered model airplanes weighing 55 pounds (25 kilogram) to 77.2pounds (35 kilograms), with fuel, ready to fly.

I assume it never does close? One thing I noticed is if your front strut is low on air (causing the wheel to be closer to strut), the wheel will not rotate all the way in the wheel well resulting in the gear door hinge getting caught up on the wheel. Worth a shot to look at it.

I went with 2 Large Robart Tanks (volume is key) on the gear set. The only issue I have had so far is the forward Nose Gear Door hinge breaking away from the glue.

Hi, all

after long time repeated test,we found this issue to be addressed,

pls glue hardwood right under the current mount wood of slat servo.And we suggest to replace screws with longer big screws(about 6mm more longer) for going deeper through wood,and increase strength.,

we will update the manual as soon, and before delivery to customers that we will update it.,

Thank you for your attention!

I will try to check the door better.. in my opinion the cilinder cant hold it open.. i will try to do a slow pass to check..
in other forum someone said to use a small magnet to hold it closed.

I tried with 110 lbs. but didn't solve... i will check with the problem is the cilinder or the gear that dont close 100%

I had to do a bit of "fitting" on the nose door as far as grinding two specific places where the door liner was hitting the hydraulic steering pin and the pivot arm. Also, I cleaned out the hysol that was at the base of the door cylinder, where the cylinder nipple housing was hitting a clump of Hysol. The door operates much better after these adjustments.

Has anyone been able to use the smoke tank with the bypass or if you use the bypass you automatically forfeit the use of the top smoke tank?

I plumbed just the side tanks, used the bottom center tank as my smoke tank. Stacking the two tanks creates a problem with the intake extension by partially crushing it and you would have to remove quite a bit of material at the front of the turbine hatch to make everything fit properly. Plus the two side tanks hold a ton of fuel, figuring with a P200 rxi, would have over 11 min. Of fuel on board if I flew full throttle the whole time. The two center tanks hold 82oz. Each. So, you are reducing your takeoff weight by over 4 lbs.

this bird already weighs 52-55 lbs. dry.

The p300 uses 1 liter/min at full power, on past experience 260oz provides about 8 mins of flying. 208 oz will put the time closer to 6.5 mins, this is not counting taxing, landing and pitting which about about 3 mins so roughly 10 mins of "turbine on" time.

If any of you guys need wing/stab bags for the 1/5 SM F-16, I ended with (2) sets by mistake. They are the blue ones from SM with the stab pockets on the front. PM me or call my cell anytime-843-833-0059

Anyone have a cockpit they want to sell? The kit I'm putting together was missing this a long with various other items, need to either put some weight in the nose and just leave with no cockpit or hope if someone has a spare they want to let go of.

Skymaster light kit is really hoeky pokey, really should not have even bothered with it, no lights on the wings, and now while starting on the fuse I see this:

Why even bother cutting the lens like this?

Ordered Details4scale kit just too much disappointment so far.

Chief AIrcraft rep says the smoke tank doesn't fit so we don't include it in the kit now even though it is part of the invoice, same for many other things such as the servo arms.

Hi there, yes the other tank goes below the intake just in front of the landing gear former. Make sure to put the curved side toward the bottom. Ill try to find a pic and post for you.
