Hi Guys,
I just got my plans for my classic machine and i have a problem! On the plans the nose unit is shown as a reverse
retracting Rhom-Air retract unit mounted vertically to the back of the engine firewall. With Rhom-air gone does
anybody know of any solutions available in 2011?
Distance between wheel axle and undercarriage pivot point is 4 9/16". Nose wheel dia 2". Distance between Firewall and
Fuselage/wing LE dowel locating former is 6.5"
I have never flown an old school pattern model before so do you guys use nose wheel steering or is it not required? (can i use a
wing retract for this position rather than a nose unit with trunnion block milled for a rotating leg)
I think if i use a beam mount retract unit the air cylinder and wheel will not clear each other.

spring air makes a firewall mounted retract.

Here is a couple of threads that could help you on how to install a Spring Air firewall mount retract unit http://www.rcuniverse.com/forum/m_2827386/tm.htm Tiporare and how you could notch the front of the wing http://www.rcuniverse.com/forum/m_2434444/tm.htm Kwik Fli III. You absolutely need nose gear steering. The Tiporare thread shows the Spring Air steering pretty well.

Thanks Guys,
It seems i was being overly Pessimistic....With 3 9/16" Leg length to play with (pivot to wheel outer radius)
Firewall Mounted Spring Air will fit......
I'll do a build thread when i get to the serious bits!
As no one else has done a British Design yet !
