Official Black Horse 2350mm Gilmore Red Lion

[Twowingtj]

Looking good! I too have ordered the Skylite 5" wheels. Should have gone with them to start with.

[DaleD]

My build has slowed compared to when I first started. Apologies for the delayed updates

Prior to ordering the Sullivan Skylite wheels I installed a pair of World Models inflatable wheels but they feel a bit on the heavy side which influenced my decision to pull the trigger on the Skylites. I managed to modify the CG rig by filling in the existing 1/4-20 hole at 118mm and making a new 4-40 hole at 112mm as recommended.

With the current set up:- UMS 575 for motor, two A123 packs, BoomaRC redundancy switch and the inflatable wheels, I’m able to balance with things as arranged in the picture.

I expect with the Slylite wheels installed, I may need to move the batteries forward a bit.

Hopefully, this weekend I will be a bit more productive.

Thanks guys.

I have used the Sullivan Skylite wheels on other birds with good results. They are firm but also have some yield when used on birds with some weight to them like the Gilmore. 99% sure that they will be my choice for replacement wheels.

Twowingtj So sorry to hear about your issues. I've had mine nose over on 2 separate occasions, but for a much different reason. (My fault really) On landings when I have tried to turn around but was still going a little to fast it bounced on those hard wheels as it tried to turn which caused it to slow down and nose over. I was lucky both times.

Do you have an idea of what tire you are going to switch to since the Du-Bro didn't work out? I had been thinking I wanted a softer tire, but now i'm not sure. Keep us posted on your choice.

VERY sorry to hear about your recent mishaps @Twowingtj. Hoping you will be able to fix the damage soon without much hassle.

The kit supplied tires are really hard/stiff, they offer very little if any absorption. I have just yesterday ordered a pair of Sullivan 5" Skylite wheels with the hope they will offer better landing and ground running performance.

Got the Gilmore out for some flights after changing out the tires and elevator servos that weren't centering.

The new elevator servos fixed to feeling of being tail heavy. I moved the CG back to 115mm and it felt good and had locked in.

The use of the Du-Bro 5" pneumatic wheels did not work out well. Take offs were fine. Landings were another story.

The wheels were inflated per the Du-Bro instructions. They spun freely on the axels and there seemed to be sufficient clearance around the tire at the wheel opening.

On the first landing, the tail came up and resulted in a nose over. The bird had never shown a tendency to nose over in the past. Both wheels were spinning freely with no drag on the axles. The evidence showed that the tire sidewalls had contacted the wheel openings on the wheel pants, acting as brakes. The only damage was on the bottom of the cowl.

More air was added to the tires, so that they compressed very little while sitting static.

The second landing was looking good until the right gear hit a bump on the runway shortly after touch down. It nosed over again. This time, damage was more significant. There was additional damage to the cowl, the cowl ring was broken and the right gear tore loose. The right wheel pant was also broken.

Looking at the right landing gear, it was obvious that when the gear hit the bump, the tire compressed causing the tire sidewalls to balloon out and make solid contact with the wheel pants.

It looks repairable but, will take a bit of work. I will be going back to a more rigid wheel and tire.

Glad somebody snagged the open box deal for a Gilmore. Should be easy to fix.

foam tac works good if you don't have canopy glue on hand.

[Twowingtj]

RC-56 Canopy Glue or even Foam- Tac works on the canopy.

[DaleD]

Regular wood glue for the canopy? I assume nobody used canopy screws, right? Or would a clear glue like Goop be better?

I plan on using 2 part epoxy, maybe 6 minutes, along with 4 black button head hex screws.

Got it, thanks!

I’ve read post here which suggest the low rates are a bit on the mushy side.

At least one person has used the suggested low rate as their low rate, the suggested high rate as their mid rate and an increase of 30% on the suggested high rate as their high rate.

I think that’s how I will set up my Gilmore.

DaleD

Yes this is what I did with my Gilmore. The extra (+30%) rudder and ailerons are nice. The book high rate elevator is perfect for flying, but having the extra (+30%) elevator helps for keeping the tail down on taxi and roll out for landing.

[DaleD]

Thanks for these helpful photos. Let us know how the balancing goes. Meanwhile, I'm looking at the suggested throws. Are they pretty much accurate? 10 mm on the elevator (12 mm high rates) doesn't seem like a lot of throw for a plane this size.

First time for me posting any pictures here...

I am about 90% complete with this build. I am running an EME 70cc Twin with the auto-start.
I had to move all the radio gear back to assist with the CG but I have not completed the final balance yet.

Bonding all of the blisters on the will be, ummm, a good time, so I have left this challenge till last.

Thanks for sharing your build.

Your engine/auto-start combo appears to be similar in weight to my UMS 5 75cc. I note, with the exception of the fuel tank, you’ve place most items in an aft position. I will most likely follow your install as a guide. Should be able to provide comparative notes in the coming week.

All the best with your build, please continue to share progress.

mechwizz Thanks for sharing photos of your setup! Nice powerplant, and a clean install, too. Very neat.

For anyone else who loves this big beautiful doll, we've got one on sale in the Open Box section. It shows as "Out of Stock" now, but we'll be adding it into stock at some point over the next several hours, along with many others. Huge discount for a small hole.

Thanks for the heads up. Will MRC supply the correct covering to patch the hole? Or, will the new owner need to improvise?

Thanks

It's a beautiful engine, no doubt, but I vote cowl on.

Meanwhile, I'd love a look under the hood to see battery/receiver/tank layout and know how you balanced the plane to offset the weight of that machine.

I’m inclined to agree, will be leaving the cowl on.

I will share pictures when I situate all the internal components and establish CG.
