There is a flying video?

It was a short flight. Learned a lot from it though.
I'll let Richard decide about posting the video.

Bob,

Thanks for the update and the new information. We had not heard that you were flying level with an offset.

It looks like we will both be ready to fly around the same time. I will still plan to fly mine as is so let us know how your new CG location works out. I can always add some lead to the nose or remove my modifications. See posts #87 and #88 for my two locations using three 4s packs.

The location I originally had using just two 6s packs is close to where you are testing your new model. If that turns out to be the desired location, it would drop a pound from my flying weight.

Regards.

Greg,
Will keep you posted for sure!

To make sure that we are on the same page, I posted a couple images of the various CG settings. The first image shows the next flight attempt by Bob using the CG at the front rod. It is about 3" (or 76mm) aft of the original CG.

The second image shows my current CG of 26mm back from the original CG and 36mm when my three 4s packs are at the back of the cockpit area. I never measured the CG using my two 6s packs because, at the time, the resultant CG was considered too far aft.

I was on the center dot. Very nose heavy. I'm moving back to the front spar. I'm sending you a PM.

The Rebel taxi test was going well until the left wheel locked up. I'm not sure why yet but we didn't have the tools with us to repair it so I'll try again next weekend.

I'll post a video of what I took soon...

I had the same thing happen to me on my last flight for the VERTIGO B-26.
The nose wheel froze, so I had to remove it.
The same brass bushing was stuck to the shaft.
I removed and lubed it up.
Perfect after that.

Mine also did it during taxi test. White grease cured the problem.

Ok, thanks for the feedback. The left wheel completely locked up and would not turn. On the video, just after the left turn, the Rebel dragged the left wheel while I had full right on the rudder stick. One of the reasons I do a pre-test like this is to shake out any issues that might happen so I don't waste time at the field. I'll remove all three wheels and grease them.

On the next taxi test, we'll get some full power run ups and see what the Castle Data Logging reports.

Nice demonstration of the flying surfaces.
Interesting left wheel lockup.

The VERTIGO Rebel taxi test went very well today. I was happy with the steering control, struts, and power level. Although the Castle data Logging measured only 3200 watts, it was vibration-free and felt like plenty of power to fly the jet.

I feel the plane is ready so we plan to maiden the Rebel on Memorial Weekend.

Will Papa Jeff be videographer?

Good luck! Where is the CG?
Bob

Greg Covey

Thanks, guys. I'll be on the video and PJ will be the photographer. Now if it will ever stop raining!

Post #105 shows my current CG of 26mm back from the original CG.

Unfortunately, the field was too wet and mushy this weekend to test fly the Rebel. We'll try it again in two weeks.

Hopefully, June will be a drier month for us...

Greg Covey

Working overtime and Saturday along with a poor weather report for Sunday pushed off my Rebel maiden flight once again. We have another local event in two weeks so I will reschedule my testing.

Greg,

I think you should just ship the plane to AZ and let Bob Ruff and Mike Pope handle the maiden. Between the two of them it will work out good. Ya know there is lots of talent out here in the West, and the weather is very favorable to good maidens on paved runways. Especially since Airshow RC is based is AZ.

After all this time aren't you ready to travel to the West and experience the future of RC aviation. LOL


Greg, do you miss my razzing you? Well, I still quote your advice given way back in the beginning days of nito to electric conversions. Your engineering expertice is very well respected.

Chad, thanks for referring the L39 from Airshow RC, the guys just love that plane and it makes me look good flying it.

Yes Al, the L-39 is a great flyer! Definitely not a knee knocker!

Got my next big relaxing foamy almost ready! 63" Mustang from BH. Kit only with me installing name brand electronics... Hacker motor, Hitech & Emax servos, Castle Ice ESC..... should be a real floater with over 200 watts per lb!!

Greg Covey

Hi Al,

Yes, sometimes I miss the love/hate relationship.

We have both come a long way with the new technologies. One thing I've learned over the years is to be more patient. If the flight environment doesn't feel right, just pass. Our weather has been unusual this spring but we have been spared all the natural disasters that other states have seen.

Only 12 more years until retirement. Best wishes that we both make it!

Regards.

Thanks, I only have few years to go. Other than the Colonol guy I might be the oldest guy out there flying RC Jets. I didn't say flying good, I just said flying. Bob Ruff is the second oldest behind me. LOL

Anyhow, I have looked at that Vertigo several times. Ya know, looked, walked away, came back, looked again. Then, finally walked away with a question mark expression.

Glad you are doing a review and looking forward to the flight video. This plane might end up being a real good flyer.

take care

We tested the Rebel on grass last Friday and it did not have enough power to take off the wet rather sticky surface. I captured it on video so you can see that it was a close effort. The Rebel did taxi well but we decided that it needed drier grass or pavement.

The following day, I kept the Rebel on display at the R/C event. A couple guys asked me if I planned to fly it and I told them our story from Friday. They then revealed that they fly at a private airport only 20 minutes from where the event was held and the owner loves R/C planes! We were elated to finally find a large paved runway in our area in which we could fly our models. We plan to re-test the Rebel on pavement in a few weeks after the 4th holiday.

I see those little jet wheel were half buried in the grass.
