What's up with the bomb bay in the specs? A10s don't have bomb bays bays right?

Correct and the A-10 (model or full-scale) doesn't have a bomb bay.

I'm interested to hear if the V2 gear solved the gear issues mine had.

I’m pretty sure that’s a leftover from copying and editing the B-25 manual to get an A-10 manual. It continues in the A-10 manual. The decal picture shows the B-25 Decals and states that you need 2x 6S – 500KV 4020 type motors.

PeterGRC Welcome to Hobby Squawk and thank you so much for sharing your knowledge and build with us! I look forward to both!

[PeterGRC]

All, I believe this is the same version as previously sold by RC Aerodyne. I built the B-25 previously and am Re-building it again (lost Rx power during end of maiden, ouch).

Now I also have this A-10 with the v2, reinforced, landing gear, so thought I would start the build and do a build thread here in stead of on RCGroups. James B has encouraged me to do so and to do it near stock so will start with posting a couple of pictures from the unboxing. Look forward to any suggestions and will do my best to capture a good part of the build.

Since it has some similarities to the B-25 from Roban, I hope to share some of the techniques I learned there.

ps...….. the battery requirement is understated by half in the product required section.
It is going to require 2 4000-6000mAh 6S in series(12S) for each EDF for a total of 4 6S packs ( 2 serial packs)

Good catch. Updated. Thanks.

[Aros]

Sorry fellas I don't have any answers to this version outside of the upgraded V2 landing gear. I downloaded the manual straight from Roban's website so unless they have updated their manual and forgot to add it to their site, that's the current manual.

Here's the manual:

So I believe this just answered my question from the prior post.
It is the same manual that I downloaded two years ago other than the front page now has motionrc.com listed on it.

Hi Aros, can you let us know if there are any new improvements or upgrades for this latest release?...Thanks

Same concern. Is it an updated release or just a re-release of the same design from 5 years ago??
It has been well documented that this had some structural issues when distributed by RC Aerodyne @ Scaleflying.com(They dropped it and took up HSD jets)
I was going to go for one after I lost my FW version to TIA 2+ years ago but put the binders on this when the deep dive on truths started showing up.
Engine pods were designed for ChangeSun 120 EDF's and were very difficult to mod for more reputable/reliable fans.
Wing structure issues were also concerns.

This would be an absolute if my concerns about prior issues can be alleviated

Any known abnormalities in its design causing unwanted pitch changes during throttle alterations?

[T-CAT]

Holy moly! This is awesome to see composite jets being offered now as well. I hope to see that continue to expand in the future.
