The Losi 5ive-B from Mike Humphreys is still dirty after a great week in Austria during the Largescale European Championships 2015. We took of the hood to show you what Mike has done to get a Losi 5ive-T that fits within the EFRA regulations.
Why spend so many time to convert a 1/5 car into 1/6? We explain!
The Handbook says...
There is a strict handbook with regulations made by the EFRA to participate in official classes. The 5th scale off road isn't part of that handbook so all Losi 5ive-T drivers are excluded from participation unfortunately. These are the limitations:
Width: 480mm with full compressed suspension
Height: 360mm with full compressed suspension
Weight: 10kg min and 14kg max
Motor: max 26cc
The only possibility to compete within the European Championships is to convert a Losi 5ive-T into a smaller sized buggy. But this isn't simple at all because all dimension are to big, even when you remove the front and rear bumper.
Mike's Losi 5ive-B
Mike has done a lot of work to fit the Losi within the regulations. First challenge was the chassis plate. Mike's challenge was to have a car which has the dimensions of a 6th scale. Earlier we have written an article about our own buggy which is also able to compete during the Euros because we used the Losi Mini WRC suspension arms. But the car is the long and small so there is a risk for overturns. With Mike's conversion the cars geometry is much better because he modified the chassis plate. The modification is done with just a file, handsaw and drill bits so nothing fancy at all. And why not using an existing after market conversion? Just because he had all materials and with some work and time he was able to make it by himself.
One of Mike's requirements was to use a Lightscale Airbox to get a optimum airflow through the engine. When using this airbox the standard Losi fuel tank didn't fit anymore. Mike is having a big history with FG cars so he took a FG tank which fitted perfectly.
And then the exhaust. After he made all modification a 'standard' tuned pipe didn't fit also. Also here his experience with FG was very useful because the Samba pipe for FG models did the job.
The rest of the car isn't that special and is using tuning parts which we see a lot by other drivers. Double steering servo setup, some alu parts for extra stiffness and MCD buggy tires. The used body is from Grafil Bodies and still our favorite. The rest of the car is just a Losi!
We had a good chat with Mike after he performed at the Largescale European Championships 2015. Mike has a lot of experience with largescale driving on such a high level and was always using a pretty standard car, such as FG. But Mike wanted to drive a Losi 5ive-T and it was the perfect platform for this project. Our question if he will do all this hard work again on a car he said "No i won't".
The performance of the car was good but the weight is an issue, even after all those modifications. The car now weights 13,9kg and that was enough to get in this competition. But for a good competition the car is still 1kg to heavy. Other 6th scale cars (such as Elcon Imp4ct, Hormann HT-3, MCD RR5 and FG) are around the 12,5 and 13,5kg and that's why the Losi isn't capable to compete. But hey, Mike ended in the 1/16 final which isn't bad at all!
In short the car was good but not great. It was probably the strongest car at the event - I'd go as far as betting that it was the only car that didn't break during the whole event - a battery wire broke but that was it...by - Mike Humphreys -
One of the biggest benefits of the Losi was it's strength and reliability. The Losi was capable to drive an whole week long with no breakage. When you have seen the Euros on RC RacingTV you also have seen a lot of breakage by other cars because of the hard track conditions.
Our opinion about the Euros for Largescale
It isn't strange that Mike wants to compete in the Euros for Largescale. The fact that you're driving within such a competition is great. Spending a whole week long with lots of Largescale enthousiasts and the best European drivers. But is it attractive and do we get the most out of this class? Our answer to this question is definitely no.
Let's compare Largescale with for example 8th scale. Within 8th scale there are participating lots of commercial brands such as Hotbodies, Kyosho, Serpent, Mugen, TLR and so on. These brands reserve budgets for marketing and presentation by races. Those who have seen the Largescale finals last week must agree that it isn't attractive at all. The track, cars and drivers are great but the whole presentation and communication needs more attention. There is no public during these races and the only people who are watching all the action are mechanics and drivers. Also the most populair RC channels didn't write about these Euros, except RC RacingTV. But a platform such as the Euros can attract new drivers to let the class grow. To achieve this there is a need that commercial brands are stepping into the 6th scale class also. Do you think this is going to happen?
One other possibility to make the Euros circus attractive is to allow 5th scale. Wouldn't it be great when there is an official Shortcourse class during the Largescale European Championships? And what effect does this have on the popularity of Largescale? We think the effects are huge. Don't you?
