Finally got my motor replaced!

So in the last week I did a few mods: Installed a CC BEC, installed retracts, installed 5 HS5085MG's, picked up the optional 4000mah battery pack, put packing tape on the rudders, separated both rudder servos and the steering servo into different ports on the receiver, programmed speed brakes, (I'm using an AR9020 with a Dx18) programmed the steering servo to not move when retracted, limited the steering travel a bit as for it to not bind, (rudders still have maximum travel) and added an axle into the bottom of the tail fin with two wheels on either side. This gives me about 7 millimeters of extra prop clearance and provides a much smoother taxi, takeoff, landing, etc. I also did not lose much of the maximum angle of attack.

After programming all of the mixes, I was kinda surprised to see that I used 9 of them But now I don't have to worry about any harnesses coming loose in the servo lead causing a failure.

Any feedback would be cool

How did you manage to fit the 5085MGs did you trim the servo tabs, or mounting plate?

Post pic if you can of the 5085 mounted

Thanks,

FCA

Ok for those of you who plan on installing HS5085MG servos in the wing

You will have to trim the ridge on the servo tab, and modify the servo tray, by removing material from the inner walls of the tray, no way is the HS5085 gonna fit without doing this

I actually removed both servo trays, and am modifying them right now

I'll post pics later

I also ended up cutting a little bit off of the front of the plate, so the servo arms I am using would have proper clearance

Maiden of my stock set up went as well as one could expect. I flew mine at my club field with about 20 guys all stopping to see it go. With all the years of big heli and 6 cell EDF flying you would think the knee knock would be low. Nope

I took off into 8-10 mph winds on the short grass. No problem with clearance for the prop of issues with bumps causing prop strikes. Our field a close town dump cap so its not perfect. Fears of tearing up the plane before leaving the ground were not realized.

Once airborne with a normal 50 feet of roll I had my hands full. The elevator needed up trim. I had my 4000 nano pack fully forward and I think the cg at the forward setting may be at work here causing the nose heavy feel. Once trimmed I was able to raise the retracts. This had the plane fly straight and true.

It wasn't super fast but it is fast. First flight I never turned on the VT. Landing was uneventful. I gave her a lot of room on the final based on feedback here. It does need to bleed off speed but it does slow way down and I had a gentle landing with no bounce. I think the headwind helped slow things down.

Next flight was more fun with the VT turned on and I got the plane into the boomerang. Another easy landing. Pretty great design and not just another plane that does the same thing as the rest of the fleet.

Nice pics FCA, I did the same

Before I try out the speed brakes, have any of you? lol, I don't know how it's going to work out, and if they will be suitable for landing. Also have to experiment with elevator comp. Next few days should be fun!!

i like the idea of the wheel on the middle fin, i will be looking into this. i have given up the the TV servo, mine is removed and will stay so after 3 crashes due to servo jamming. keep a close eye on that 26g MG eflite servo, it starts making noises then it ll start sticking

Hey jbug, I'll post the part numbers I used to accomplish the "fin wheel" when I get home. Note: a dremel will be required!

good luck with that... i found i had to put the 3300 battery all the way forward and still a tad nose heavy. be sure to slow it way down when you land, im talkin bleed off ALL your airspeed before you touchdown or it will bounce right back up into the air and come down hard

After three successful smooth landings on my Scimitar I had the dreaded bounce on landing. The retracts bent backwards as I stalled post bounce and landed hard. At least they didn't pull out. I was coming in hotter than previous landings but it looked smooth. I was surprised as the bounce and how high it went and how quickly it stalled back onto the mains. It wasn't pretty.

I also have had issues with taking off the ground and suddenly pitching up too much and then over-correcting almost putting it into the ground. I may adjust the downloaded settings on my DX8 for the model. I don't know if its more expo or less. Sometimes too much expo puts the steep curve right where I have want the stick. I never use expo on my heli's and only use it on my larger built up 3D planes that have silly travel on the controls.

Thanks for the advice...I was planning to use the technique detailed a while ago in a post...to get it to about 5 to 10 feet...cut throttle, and then use elevator to slow and land on mains. Your thoughts?

Thanks,

Wes

I think you will be still flying to fast for landing. Better start bleeding off speed around 20 feet or so. This is what I am doing.

agreed, i give it like 1/3 throttle on my base leg... compensating as neccesary to maintain altitude in my turn. but as soon as i hit final im almost power off, just working the throttle enough to keep my rate of descent.
