If looks count for anything they do look really nice.

Hi, new guy here. To help out GBL who is an outstanding videographer of my Bronco, I'll post some specs of my OV-10 to answer some questions that were asked on this thread.

Motor - Rimfire 32 x 2
ESC - Talon 90 x 2
Props - APC 13 x 6.5E x 2 (one is reversed)
Spinners - DuBro 2.5 inch x 2
Batteries for motors - 4s 5000 x 2
Electronics battery - 2200 Life
Retracts - Eflite 90-120 90 degrees x 3
Servos - Hitec HS-225MG Mighty Mini x 8
Graphics - Callie Graphics 1/7 VMO-2

Flying weight, I don't really know because I have not weight it yet. I get six minutes of flight time and landing around 50%. Mixed throttle, to include high speed passes. Most of the flight are done at 1/2 to 3/4 throttle. Since the video was taken, I got brave and have been doing basic aerobatics that this aircraft would do IRL. More than enough power with this set up. She takes off from grass with no problems. Very stable flyer with the counter rotating props. Pilots and exhaust will be added as soon as they arrived to add more scale to this a/c. The only mod I really had to do was extending the standoff for the motors. The retracts were all dropped in with no issues and the supplied struts slipped on with no modifications.

Thank you for posting all of these details Robert!

[GBLynden]

Thanks GBL.. for the video. I actually took a snap at the end and used as my desktop!! How about some details on his setup if you can so we can start compiling what works and what doesnt. First question, i assume those are the Callie graphics for VMO-2? Same set im using as i grew up watching these in person. Camp Pendleton is where i started my RC hobby and on the same airfield that very plane was based.

Very cool! I have two more flights left to edit too

[MikeT]

Mine showed up also. No time today to mess with them.

So my Xwave retracts were delivered today. Other than being black, they are exact replicas of the E Flite 60-120 main gear retracts. The only way, at least that I can see, to keep the strut in the trunnion block is using the centering spring as a retainer. I'm not sure about that. On the plus side, they do install with no modifications to the mounting surface and fully retract the nose wheel into the wheel well.

Here's what I'm thinking for the nose strut..............the YAK-130 nose gear w/ 105 degree etract and setting it up like this 96 inch version and another view

[Boots Whirlygig]

Hey Alpha! Have your design engineers replicate this in 1/7th scale!

Good advice. Thanks. If the XWave retract doesn’t work out, that’s exactly what I’ll do.

Keep in mind that screws are a good “weak link” in the event of a bad landing! The nut and bolts would result in significant damage passed on to the structure and gear, not that there’s a bad landing in your future!

[MikeT]

My set will be here Saturday from tracking. It will be nice to check them out and see just what's going to work.

According to Motion the nose is the same retract as the mains.

Mike

Thanks, just ordered the third retract.

[Kangi1954]

Hey Kangi1954, with the mains above the mounts you could, in place of mounting screws, go with 4-40 bolts and blind nuts. It shouldn’t interfere with changing the retracts later.

I have a 60-90 Eflite Nose gear here so when the Xwave arrive I'll figure out which way to go.No way I'll do the Robart for a couple of reasons. 1 cost, this air-frame is sport scale 2-weight

Mike

I'm with you. I have the 6-120 E Flite 90 degree retract as well. I even had it installed. But I don't like the fact that it must be mounted above the wood mounting surface which means any and all stresses are working directly against the mounting screws. I'll try to figure out how to use the X Wave once it gets here. I wish someone from Motion RC would clarify the strut installation for us as that is my only question. How do we keep the strut in the trunnion? The spring? The upper set screw in the strut slot? I don't know.

[MikeT]

Well i use the Eflite Retracts all around the gears 105 for nose and 90 for mains and they feel sturdy, i assume that they will do the work for a long period as long as i landed as it meant to be. I have the Nose 105 Robart retract that i ordered before the eflites, and ordered the xwave for mains just in case i needed.

Since the mains from eflite are on back-order till September I went another direction. I like the eflites just want to get this thing assembled, I can always do a swap if I think it's necessary. Even the eflites are subject to failure on a bad landing. Even the best flyers screw up..

That's what I was told as well.

I assume a nose retract is not far behind?

and yes, I picked up two also.

I already have the Robart 105 nose retract that i will save with the xwaves just in case.
