Hello All, just purchased a TF Gold. Probably will not get to building it anytime soon but really want to scale it out with a Mid-Engine 
. Lets see how that goes, already started reading the mid engine setup and not looking too promising but I have time . Will scan through through this thread for all the help I can get.
Anyone with retracts no longer needed?

Hi Rowdog! I bought my P-39 GE kit little over a month ago as part of a package deal with two other kits. A couple of weeks back I was able to locate the Robart nose gear for about half the cost of a new one. The main gear should be easier to find but I haven't look yet. I recommend a "WANTED" ad on RCG to find the nose gear it worked for me. Fiberglass Specialties still has the half cowl for $28, I prefer fiberglass over plastic when available. I found a guy selling reproduction TF cockpits here: https://planesgoneby.com/products/TF...Kit-p456601938 I haven't ordered mine yet shot the wad at FS.

I found the main gear a bit confusing with the manual calling for one model Robart mains and the Robart Gear Finder listing three different model numbers. I think the main thing is to use a 85 degree main matched to the finished all up weight. I plan on going whole hog and using Robo Struts on the mains like on the nose gear, they look so much better than piano wire. Have you seen the new Robart quick disconnects with the check valve built in? The model number is 190-CV.

Yep, looks like it would mount about 3-4 inches behind the CG point. Probably could move the servo battery and maybe air tank(smaller) forward of the engine. Also possibly mount the battery in the nose. These are just thoughts because I have read not so much on a mid-engine mount nor have I seen one . I heard one existed but have not been able to find any details 
. I might end up going with the norm . The RCV90 is about 29 oz and swings a 15x13 3 blade prop which should be good. If this builds like any other warbird then it will be really tail heavy . Hopefully I can find at least one other person that had tried something similar .

I`ve got a 2,5m P39 with fiberglass fuselage and foam wings. Long therm project but I am thinking of a MVVS Water cooled center mounted enigne.
Anyone here ever seen or tried a MVVS Watercooled engine?

I was thinking about your mid-engine idea, are you going to have room for the air tank or will you with electric retracts? I just made a deal with a guy for an extra set of # 605 Robart gear they are 90 degree but with a little work should work fine.
I asked Robart why I find more than one gear listed for different TF kits and they explained it to me. The less expensive gear with the wire legs are entry level and designed for builders on a budget or want the more forgiving spring wire when you make a less than perfect landing. The 5/32" wire can handle harder landings without damage than an oleo strut. The more expensive sets are more scale. Robart is trying to give us a choice. I think I will stick with the wire on the mains until I prefect my landings and then change over to oleo struts.

The hard part is the correct specially made nose gear. I paid considerably less than the new price but it was still more than the main gear. I didn't think a generic wire nose gear was going to sit and look right so I bit the bullet. I don't have to tell you building is about compromise but its part of the fun.
