PR Bushwheels - CARBON Z CUB landing gear upgrade

Hello everyone, 

Here we are with the PR Bushwheels - CZC landing gear upgrade kit offered by us.  You will need to supply the Eflite 25E Landing Gear set from Horizon Hobby (EFL460016).  With the landing gear you purchase, you will need to drill out the receiver tubes to 3/16" to accept our axles.  Also provided in the kit are 2 grub screws that are 8-32.  You will have to tap out the existing holes which are a smaller metric threads.  

When assembling the extension tube to your X-brace Cabane, in the video I talk about using SILICONE to assemble them.  Instead USE JB-WELD to attach the tubes.

Please enjoy the video and don't hesitate to reach out to us if you have any questions.

Hello again everyone.  Well PRB has been keeping busy with our mission of making quality products for you flying enjoyment!

Recently we worked with Andrew Griffin from RC Flyer Magazine who has put a couple of planes together with his friend Kevin with our bush wheels, struts, and tail wheel.  Great looking planes.  These are the Hangar 9 1/4 Scale PA-18 and the Valliant. 

Have a look!


Un-boxing the PR Bushwheels in Australia - Chuck T. Seeker

Hello folks,

Please have a look at Chuck's newest video.  He has done a video in one of his reviews of  a set of 1/4 scale PR bush wheels, tail wheel, and shock struts.  We invite you to have a look and even subscribe to Chucks site.  Thanks Chuck for your support and the great videos.  I can't wait to see your cub in the air!

Happy flying everyone,


Bush wheels and rough landings: via Larry AK Cub

Hi folks,

Steve here again.  For those of you that have questions about terrain, landings, and how our shocks work out on the airframe, I would like to direct you to the link below to Larry AK Cub out at our Big Lake Alaska flying field, AKA Bush Pilot Estates, and see Larry flying with a new set of improved and balanced 1/4 scale PR Bushwheels!

The shock struts articulate very well, and even if you don't have our bush wheels yet, make a very nice added piece to your airframe.  No more bungees to break or week springs to replace.

Enjoy the video and watch as Larry finishes of with a little one wheel hop!!


Look what's coming! It may be looking like a 1/3 scale tail wheel assy!

Hello again,

Well I wasn't sure if I wanted to post this picture just yet, but what the heck.  In our GALLERY is the 1/3 scale tail wheel assembly that Robert and I have been working on.  You don't get to see the actual tail wheel just yet as it is still in the mold, but soon!

Once we get it all dialed in, we will be selling this as well as the 1/4 scale complete tail wheel assemblies on an build to order basis.  These will be only built once the order is placed.  We don't have a price figured out just yet as these are a bit labor intensive to build.  We are using actual spring steel for our assemblies to give them a much more realistic look.

You will notice that there is not a turn spring attachment just yet, so as we get closer to completing it I will update the blog....

Safe flying out there and thanks again for all the support and feedback on your experiences with PR Bushwheel products.


Dave Sullivan and his World Models clipped wing cub

Hello all,

I would like to share a link with you from Dave Sullivan and the posting of his YouTube video flying his red and white World Models clipped wing 1/3 scale cub.  He is sporting a set of PR Bushwheels 1/3 scale (11.6") tires and they look great.  We get a great shot of the tires, and even a one wheeled touch and go down the runway, but I have to say that even more impressive is the flying by Dave!  Thanks again for sharing Dave and we continue to look forward to working with you...  The tail wheel is coming soon for that plane!!


Starting out with your new PR Bushwheels

Hi folks,

This section is to give you some pertinent information when you take your tires out of the box for the first time.  Keep in mind that these are in fact "air filled tires" just like those on your car.  Thus temperature variations do cause pressure changes.  In fact, when you first get your tires, then have more than likely traveled to you via an air cargo service which means they have been up to altitudes above 14,000 feet.  This will cause the tires to swell as the atmospheric pressure decreases.  Unfortunately we don't get to control this aspect of the shipping, so please check you tires out thoroughly when you get them to make sure they don't leak.

When you first get your tires, you may have to increase or decrease air pressure to ensure the proper inflation for you airframe.  (We hope to be doing a video soon).  Make sure you DO NOT push in your valve stem.  Simply unscrew the 6-32 valve screw and if you have an air compressor, hold the nozzle slightly away from the vale stem hole and apply just slightly more air pressure than you think you will need.   Quickly put your finger over the hold and then re-insert the 6-32 valve screw with the O-ring.  Do not over tighten the valve screw.  It simply needs to be tight enough to slightly squish the O-ring.  Don't squish the O-ring out past the screw head.

Another method to be able to inflate your PR Bush Wheels out in the field, is to purchase a small sports air pump for inflating footballs, soccer balls etc.  Cut off the hose attached and find a small piece of 1/4" I.D. flexible tubing (rubber or acrylic commonly found at Home Deport or Lowes) and slide it over the end of the pump where you cut off the original pump's hose.  This 1/4" I.D. tubing will fit over the valve stem and allow you to put pressure on the side of the tire while you are inflating by hand and not on the valve stem itself greatly reducing the risk of pushing the valve stem into the inside of the tire.

If you are outside flying on a hot day, keep in mind that your tire's pressure "WILL" fluctuate.  you will have to be aware of your tire's pressure for proper performance of the bush wheel.

Lastly, I would like to wrap this posting up to inform everyone that Robert has tested the tires in an oven up to 200 degrees F, for two hours.  Though the tire was extremely hot to handle, there were no deformities and the rubber remained strong.  We are very happy with the results of the test for those who will be flying in the warmer climates!  Keeping in mind that here in Alaska, well lets just say that if it's reaching 70 degrees, a lot of us are whining about the heat!

Take care everyone and happy flying.... Please send in your comments, good or bad, we want to know what you think.  If there is an improvement we need to address, or a deficiency we have not considered, we are truly open minded people and welcome your thoughts.


Check out our great supporter and RC enthusiast Larry AK Cub!

Hi folks,

Steve here again.  I want to share a few links with you to our great friend and huge supporter, Larry Weeks.  Larry has been flying our 1/4 scale tires since the very beginning.  I would like to point out that in many if not all of the videos he has posted on YouTube, his tires are not balanced.  So as you can expect, the tires that you will be receiving will perform even better! So please, come have a look at Larry's page and even subscribe... I have!

Oh, by the way, I should point out that Larry is a member of our local club and we get to fly together often.  These shots are all from Alaska, and yes, we do fly in the winter!

A look at Craig "Nooch" Harding and his 1/3 Scale World Models J-3

Alright, here we go!  So Nooch is a friend of PR BushWheels as is his brother Bruce.  We are very happy to know them both personally as Bruce lives in Alaska and Nooch comes to visit us!  Unfortunately when the weather here turns a little cold, they head for a little warmer climate!  LOL!  Can't say that I blame them sometimes when the temp drops to -30 degrees F and we don't get to go fly!

So here is a link to Nooch flying his 1/3 scale World Models J-3 with a set of 1/3 scale (11.6") PR BushWheels.  I hope you enjoy.


Hello Everyone

Yes we are back in production with some great tires. There is expected to be a very high demand on our re-release of PR Bushwheels, so please be patient as we get our orders out to all of our customers. Robert and I hope to be adding additional postings that will show video links giving you more details on caring for your PR Bushwheels, landing techniques, as well as how shocks and tire combinations work to improve your flying experience.

Hope to hear from you soon as our product get out into the field.
