500 Size AH-64A Apache build

[eawings]

Roban personnel returned back to work after their month CNY (Chinese New Year) celebration. We were expecting a container load of spare parts that we have placed an order 5-7 months back and still have not been delivered hopefully with helicopter Kits included. I still have to coordinate with our new PO rep what kits are being ordered and ETA. I'll keep you posted once I hear from her this week. So far, Roban will continue their production run for Motion RC. I am well aware about Roban's counterpart in Germany. One of the German dealers sent us an email wanting to offer us their remaining floor stocks but negotiations with our Product manager are ongoing.

F106DeltaDart,
You've come to the rescue again! I'll send you a pm to make arrangements!

eawings,
I'm that guy you helped for the AH-64 gear set. I mean no offense and was just puzzled that an invoice comes in from scaleflying but my ticket response from motionrc support. At any rate, I see it's legit and have paid accordingly. Thanks for your help.

Going thru the model further after my hard landing, I've also discovered a crack in one of the boom blocks of the 45 degree elevated tail assembly. The plastic blocks where the main tail boom and shorter boom plug into. It cracked/broke around one of the bolts that secure the block to the fiberglass plate. Outside of trying to find/order a new/complete elevated tail assembly, has anyone had any luck making repairs to the block? Would 3d printing a block work? Maybe cutting down a tail case to use as a new block?

Any ideas or suggestions appreciated!

I actually have a spare raised tail belt assembly if needed. I went with a torque tube conversion on mine, so I still have the stock one lying around.

I was going to get the Huey but they sold out before I could make up my mind, I then was looking at the Lee County actually, then decided I just love flying the Hughes 500D or E models and the only one they have left is the Sheriff version, it is the E model so I would have a D and E model, but I still can't decide on that or if I even want to build any more, was hoping Ed would answer my question first........

Kinda like to see DC knotted up with a Lee County EC-145.

Mr Ed, do you have any info on when the next load of scale helis or parts from Roban will be coming or is there nothing being restocked?? I sold three of my Roban helis but wanted to replace them with new projects, I just don't see anything thats in stock now that I want, I would like to know if there are more coming soon before I spend my money elsewhere...

you need a huey, Just saying.

So I got this guy a set of the AH64 Main gear and had RCA set aside one for him. He needs to send that PayPal payment through if he wants that mailed to him. And no Motion RC is not connected. You sent both these companies an email.

F106DeltaDart,
Thanks for the reference to Motion RC and your kind offer to sell your spare.
It seems Motion RC was able to do something... It was strange but my inquiry into Motion RC resulted in a reply saying that Motion RC didn't carry the gear but they were able to set aside a gear for me at scaleflying.com. I had previously called scaleflying and spoke with someone who was "going to check" for the gear but never heard back. Now I get a $23.99 paypal invoice from scaleflying and it seems facilitated by Motion RC. Are they connected?

The short answer is an in between. One of their heli service reps is a former scaleflying employee and lives in the area of their warehouse. Although they don’t carry Roban anymore, they still have a lot of old inventory around. Sometimes, he has been able to check their warehouse and hunt down weird parts that Motion doesn’t stock. So yes, the invoice is legit.

500 size AH-64
I was test flying the mechanics of an old rc aerodyne kit and lost power after a ground hover climb out (~15ft) to test tail gyro holding. 1600 rpm governed headspeed thru esc. This is belted model.

Headspeed dropped and the heli had a hard landing. Had control on the way down so it hit level on the skid. This is my auto gear. Teeth are all fine as is the main gear teeth. Seems like the plastic just gave way from age brittleness.
Does anyone know of a source for these special gear sets?
I’ve got inquiries into scaleflying US and Germany.
Anywhere else to try?

Well shoot, that’s quite the failure. I’ve gotten all of my spare gears through Ed Adriano (Motion RC Heli tech). They take a while to come in, but if you send Motion an email they should be able to special order some. Alternatively, I’ve got a number of spares, and I could sell one to you if Motion can’t get it,

Dammit... got a whole operation going on!! Looks good!! Where's the MRAP from?

Thanks, it’s the HG MRAP from Legend Hobby. Pricey, but worth it. I’ve never seen a ground vehicle with so many features and details.

Yes, looks great Delta, my 700 Apache does those pedal turns, the servo in it now has 111oz of torque, wonder if I stepped it up to more torque it would be better for the cascading tail??

It certainly can’t hurt. I think a combination of a few things helped solve my issue.

1. Eliminated the flexible Sullivan golden rod I was using for tail control. Built a rigid bellcrank type system instead.
2. Sped up the tail RPM. Went from a 26 to a 21T pinion for driving the tail.
3. Went to the nuclear option tail servo (~500 oz-in torque)

So I can’t say the tail servo alone solved it. But it certainly was the one that made the most immediate difference.

Looks awesome F106…great job!

[F106DeltaDart]

A few photos from flying this morning. First time out trying the new tail servo in some heavy winds. It performed perfectly! Tail held rock solid. I think that I have finally cracked the code to making this an everyday flyer!
