I recently returned to Ukie after a 40 year hiatus. Continuing as an R/C Pattern flyer ,but I thought I'd dip my toe in once more to see how it goes. So I bought a Nobler ARF(coulda and shoulda choose something better) and thought I'd economize by using one of my Fox 35s from the early 70s. The one I chose was new and I decided not to lap it in like the days of ole'. I did bench run it for an extensive amount though.It's gone through a fair amount of 5% nitro/ 28% Castor S&W and some with 10%. Swapped out the NVA with one from R.S. It runs like any, stock moderately broken-in- Fox 35s and it will probably get a bit stronger and friendlier with another 5 gallons of fuel and perhaps a hemi head kit. However,the plane seems down on power( weighs just 40 ounces ready-to fly without fuel), even though I clearly remember that my Fox 35s pulled my Detroit Stunter, Smoothie, and J.D. Falcon II -no sweat back in the 60s.
I've narrowed it down to a BRODAK 40 or one of the new Enya 40s(SS 40S or the 40 XZS) . The Aero Tiger 36 is intriguing, but it deserves a better mount than a Nobler ARF. I'm interested in which is the most thrifty with fuel as I can only squeeze about a 3.5 ounce Uniflow in the tank area as the plane is completed. Long story short, the stock plastic tank is unsuitable for U/C as it is an R/C tank- Had I known before mounting the wing, I could have put in a 5 ounce Uniflow with easy before -the -wing -is-attached mods.
I would appreciate feedback on these engines and first hand knowledge of which would require the least amount of mounting modifications. I've already purchased a new cowl.
I really hope to not debate Fox 35 engines- I love and continue to own some really perkin' Fox 36XBBs that were modded by Larry Scarinzi and I think the 4-2-4 sound is pure music.
