How would a Kavan 50 twin 4 cycle engine work on this 1/4 scale J3 Cub ? Can anyone give me the inside width of the cowl? Also the distance from fire wall to front of the cowl? Thanks, John

The Bush Wheels shocks are a bit pricey at $95.00 a pair. The O ring size I have been using is #216.
ID = 1.125
OD = 1.375
Section DIA is .125
95 bucks buys a lot of O rings.
Hope this helps.

I agree, They are pricey. I think I'll try the O-rings first and if they don't work out get the shocks. I think I will try springs also, has anyone went this route?

Order them on Amazon.com and get just 10 or so to try out. I have the PR set-up and it can take a really hard landing, but some times I wish I had a softer tire (I use Dubro 1/3 solid tires) . I have a Cub with Robarts and the Oring set up and I do like the "bungee action" when I do grease it in on a dirt strip. You do have to replace the orings periodically or you will have one of those episodes where your Cub is all splayed out with a broken prop and scuffed up cowl.

I´m using springs, they works fine to me. Two springs per leg. I have to disassemble to take measures.

I have a set of Hanger 9 1/4 scale floats I would like to install on my PA 18. Would someone please advise the distance they extend beyond the front of the cowl so I can determine if it will fit in my toy hauler. Thanks.

I measured the VVRC with the standard mufflers: 98 dB which is much too loud (20x8 XOAR @ 6400rpm)
I'm experimenting with some sort of noise damper plugs. Actually I'm down to 82 dB but the engine runs lean and becomes hot. Still on the way to optimize....
When I'm finished I'll post a sketch of the dampers.

Have you had any luck getting the engine to run cooler with the noise damper plugs? I also need to quiet down my VVRC 40 in the Cub. Looking forward to seeing what you came up with.

Yes, I got it! Had to shorten them a bit, now it works fine. Lost some rpms. Have to measure the values, then I'll send the details.
