They don't seem too bad, I have a habit of adding glue everywhere as is. Is PR bushwheels still around? I couldn't find any with a quick search.

PR Bushwheels' owner had passed away maybe a year ago now. His son may restart the business. I had got mine used in December, always wanted a set for a future bushplane, jumped on the opportunity, and six moths later this plane came out.
8" AirTops are the closest a guy can get here in the US through ESpirit. They are made in Europe.
PMT's would be another choice but the sizes are a little off. 7.75" and 10.25" and you'd have to make an overseas order. They are much lighter than the other choices out there and $160-180 USD a set with the 19% tax removed and not including shipping across the pond.
Yup adding glue everywhere is just a given, but what's bad is the fitment of these parts and there have been joints simply without glue. interlocking pieces that were not even pushed together, or pushed together with force allowing the ply to crack.... That's no good.

All the joints have been epoxied and looks good. So installed the ESC and the motor. Put all the air ducting in place and now it is ready to install the rest. Curious how the weight will be and the balance. Just put the two power batteries on the scale and the two weighed in at 52 oz. more than I expected.

Well put the plane together with everything in all the batteries ready to take off 20 lbs 10 oz. that is not to bad but still almost 2 pounds over the maximum advertised weight, and I have not add a thing the plane is stock.
Anyway have a question to the people that are flying the plane it came out a little tail heavy. The max CG in the book is 4 inches but mine balances perfectly at 5 inch. Is this flyable or do I need to get it back to 4 inches, your help is appreciated thanks.

5” is perfect, I moved my CG aft to get to 5”.

Thanks Nick that helps, saves me adding some weight.

Going to strip everything off the front and see if I can mount the two RX batteries on the motor box and that everything clears . Will have to come up with some way to charge and discharge the batteries with out removing the cowl. So that means making some new wiring harnesses from under the cowl into the plane.
Question to the electric fliers the spinner with the cooling slots to cool the motor does it work and is it worthwhile to get.

There isn’t that much room in the motor box. I’d just mount it aft. 5” CG is good, but a little further back would be better I think.
I’ve run the cooling spinners on 60” planes. Don’t think they are really worth it unless you live in a place that gets over 80F a lot. Every bit of cooling doesn’t hurt though.

Thanks Nick for the help. But I still have to add the extra leaf in the Tailwheel spring so that it is as it was supposed to be. Hopefully HH sends it soon and that extra leaf spring will not help the balance. Working on the RX battery decide to use only one. Just need to cycle it to see if it is up to par, then do the installation and wiring back to the receiver and into the plane.

I don’t think the extra leaf will actually add enough weight to see a difference. I have 6oz of lead on the tail....
