retract Q
 
I dont know much about retracts and im getting a cmp 120 spitfire here http://www.nitroplanes.com/spitfire120.html . It says can be fitted with 90 degree rotating retracts. Iv been shoping retracts and i dont know the diff between non rotating and rotating retracts. I thought i understood it as the wheels rotated as they come up but by the look of this spitfire they dont need to rotate, looks like they would just fold strate up. I dont understand why it calls for rotating retracts on the model or i dont understand rotating and non rotating. Thank you.... Tony

What you have here is group of people who know nothing about R/C importing and selling models. Looks to me like it needs standard 90 degree retracts.
Check here for the same model from someone who at least has a clue:

Thanks, AK models looks like a good site. So does this spitfire only need non rotating retracs? Was my idea of rotating and non rotating right? For ex. a corsair would need rotating because they fold strait back and the wheels would have to rotate 90 deg. to lay flat under the wing?

Rotatiing generally retract fore and aft, like the underside of a corsair. Regular 90 degree go lateral like a P-51. When the gear comes down on the rotating, it starts off sideways and rotates into a normal position. Regular 90degrees just come down and your fine.

One area I don't like much is many rotatings use a bellcrank. You really need to get a smooth setup with a bellcrank or there will be binding issues. Regular 90's are very basic and not many problems

Beats me, I'll take a look------yes, 90 degree rotating. its in the fine print between the large photos. It says it can be fitted, I don't know if the linkage is already in it or what. Why don't you try and ask in a separate thread titled Nitro Spit and see who has one. I set up a couple planes for friends with the rotating. The bellcranks are the area to get right. I even Installed an access door on them to make it easier to fix problems

Looks like you need 90 degree NON rotating retracts

Yeh he's right, the description says one thing but the photo of the underside shows another

Yup. Non-rotating.

One of our members has one of these.


Nice plane, albeit it really need larger wheels... something that is not hard to mod.


Have a look at getting a set of Robarts with possibly the struts for a more scale look.

The installation will also be FAR easier...

Too bad that AK doesn't tell you about this either.
