Apologies for inserting a picture the website wasn’t liking copy/paste formatting   Looks like long range tanks are back

Nice. Which shop is this? Will have to add this to the wish list.

Maxwells - they own the STC now and as far as I know aren't yet making installation available to others - which is a bigger deal to our European and Australian friends. But that could change any time.

Don Maxwell has the Jose Monroy STC for long range tanks: https://www.donmaxwell.com/

 

Jose did the tanks on a Bravo I owned back in 1997. Back then it was around $7000 installed. Best upgrade on a Mooney in my opinion - gives you a lot of flexibility.

It's a bit difficult to use, but the FAA database says:

STC Number : SA1913SO
Description: Auxiliary fuel cells
STC Holder: KMAX Aero LLC

I have not heard of KMAX, but it sounds like a Maxwell derivative.

I have this mod on my Bravo, but do not find it particularly useful (came with the plane). With full fuel (118 gal), I would be at max GW with me as the only occupant of the plane with no allowance for luggage and pushing the forward CG limit. I know, I should lose some weight :). While full tanks would give me apmple fuel reserve, it would also exceed my bladder capacity (there are some things I just refuse to do in my Mooney unless absolutely necessary and using LittleJohn or equivalent is one of them).  

My typical mission is 2 adults with 30-50 lbs of baggage, leaving me with about 85 galons of fuel to stay within the W/B limits. So far, I have not had the opportunty to take advantage of the additional fuel capacity on this plane, but I have only had it for little of 1 year. However, folks with different mission profiles and larger bladders may find it worth the money.

It is like the turbo or ice protection--it offers options you would not otherwise have.

[IvanP]

Yes, I love the turbo. It was the main reason I got the Bravo.

Because you picked the wront Turbo Mooney.

My 252/Encore is 104 gallons.   I can carry 2 people with full fuel.  Or me and a lot of luggage.  

Flexibility

 

[IvanP]

You are probably right. But either way, I run out of bladder capacity before I run out of fuel even in the thirsty Bravo. The days when I was able and willing to do 5+ hour legs are history. Now it is 3-4 hours max. The joys of getting old.

You can pee in a bottle, but you can’t run a plane on  air.  They’ve tried.  

[BlueSky247]

Wish they could reseal the regular tanks while they are at it. And install speed brakes…

And after they are done with those, spray corrosion X for full service.

As the original poster I want to make clear that this STC does not come with Jose’s “relief tube”. 
 
Hope Jose is doing well and miss his posts. 

[IvanP]

I bet they can do it so long as you are willing to part with appropriate number of AMUs at the end. The magic power of money keeps our planes airborne and airworthy, unless you need some parts made of unobtainium, like the dreaded tubo V-band clamp for Bravos.

In the email they clarify the FAA allows an STC holder to install their own parts.  A kit that a 3rd party installs however requires PMA approval which they don’t have yet.

really wish it wasn't so damn expensive,  planning on installing these in the next 2 years.

In the grand scheme of things aviation seems pretty cheap to me.  I can’t wait to get them and spend 9hrs at FL250!

Until I can find a way to upgrade my 3.5 hour bladder, no need for a 9 hour aircraft bladder!

[Danb]

It was the first and best modification I did to my Bravo in 2006,:my Bravo had useful load around 1010 me not being a big guy along with wife we flew numerous 1000+ mile trips which I sorely miss in the Acclaim. The Acclaim has about 140* less useful load bummer, why ? 

[M20F-1968]

I have a highly modified M20F which is now essentially a J.  It has speed brakes and carries 90 gallons of fuel due to the Monroy tanks.  It range is over 1200 miles, with reserves, and longer LOP.  It allows longer range, and allows you to purchase more cheap fuel when available.  I burn 11 gallons per hour at 160-175 kys depending upon altitude due to a Rayay Turbonormalizer.  The combination of the long-range tanks and turbonormalizer turns the F model into an airplane that is more capable than the J and challenges the 231.

thought about it when I bought the Bravo, gives you an option, the Bravo topped off to the fuel cap O-rings has 102 gal usable, I keep the tanks full, so carrying more than one passenger I have to de-fuel, with long range tanks even more so, UL with TKS tank full and rear seats out is about 990lb, figured I was not going across the Atlantic so I passed on the long range tanks, very useful though for somebody who goes strictly by themselves in the Bravo

[Pinecone]

Solution for bladder range.  Better than a bottle as it gels the liquid, so no spills and it also deodorizes.
